Should you get the Preview for Windows Phone 8.1 Update? We tell you.

Earlier this week, Microsoft unveiled the feature set for Windows Phone 8.1 Update. As it turns out, there are quite a few new additions to the OS refresh that make it worth getting, including those Live Folders, rapid charging, improvements to Internet Explorer rendering and more.

However, there are many questions about the Preview for Developers program and what it means for those enrolled, but who do not yet have their Lumia Cyan update. We are going to walk through a few scenarios of what to expect depending on your setup.

The current 'hold' on Lumia Cyan updates

The Preview for Developers program is little to no risk for users, even though technically it "may" void your warranty. Having said that, we are not aware of any instances of people breaking their phones or denied service.

There is one issue though that is affecting many people, and it has to do with BitLocker, an encryption system for those on corporate accounts. People who are on the Preview for Developers for 8.1 and who are eligible for the Lumia Cyan update, cannot get it right now. Microsoft put a 'hold' on the update for everyone due to those with BitLocker being at risk during the update. As a precaution, all are blocked. The only people who can get Lumia Cyan are those on Windows Phone 8.0.

Now, three things:

  1. Microsoft is going to fix this, but there is no ETA. It may even come in next week's update, but we do not yet know
  2. IF (and only if) Lumia Cyan is now available for your Lumia, you can alternatively backup your phone, downgrade the OS to 8.0, take the proper updates and Lumia Cyan, hard-reset, and restore your backup. It is easy but time consuming to restore.
  3. Even without Lumia Cyan, you can still move from 8.1 to 8.1 Update without doing anything; you will get Cyan eventually, as you cannot miss updates. Just have patience.

For most of you, what is above is all you need to know. For others who want more, let us break down these scenarios.

Scenario 1: You already have Lumia Cyan and Windows Phone 8.1 (Lumias only)

Turn on your phone, go to Settings, and scroll down until you see Extras + Info. Open that up and if it says 'Software release: Lumia Cyan' you are on the latest update. The Lumia 630, Lumia 635, and Lumia 930 all come with Lumia Cyan automatically.

If you are on Lumia Cyan right now and obviously Windows Phone 8.1, then you can enroll in the Preview for Developers program by downloading the app, accepting the terms, and enabling it. When Update 1 is available, you will be notified that there is an update, and you are good to go.

Bottom Line:

There are no issues with this scenario.

Scenario 2: You are on Windows Phone 8.0 or 8.1 but do not have Lumia Cyan (Lumias only)

Turn on your phone, go to Settings, and scroll down until you see Extras + Info. Open that up and if it says 'Software release: Lumia Black' you are on the older update.

You can still enroll and use the Preview for Developers program. The update process below is what happens to you next week, depending on where you are starting:

  • Windows Phone 8.0 > Windows Phone 8.1 (1400) > Windows Phone 8.1 Update (141x)
  • Windows Phone 8.1 (1400) > Windows Phone 8.1 Update (141x)

If you are on Windows Phone 8.0, your phone gets a few updates to get to Update 1. If you already enrolled in Preview for Developers and you have 8.1 (but not Lumia Cyan), you simply move to 8.1 Update.

Whenever Microsoft lifts the 'hold' on the Lumia Cyan software for those in the Preview Program, Lumia Cyan is downloaded an applied to your phone.

Bottom Line:

If Lumia Cyan is not yet available and you are on 8.1 Preview, just take Update 1 and wait until a fix comes along, you will be fine in the end.

Scenario 3: Non-Lumia phones and 8.1 Update

As of now, Samsung, HTC, Huawei, and other have not started their 8.1 rollout. As such, it is unknown if they too have the BitLocker problem. Regardless, now that Microsoft is aware of it you can bet the switch will not be thrown unless they know it is safe, so do not worry about it.

Since there is no ETA on those updates from Samsung, HTC and others, if you want Windows Phone 8.1 Update 1 next week, just enroll on the Preview for Developers program, take the update and be happy.

Bottom Line:

If you are on 8.0 or 8.1 Preview, grab Update 1 if you want it next week. Your manufacturer or carrier can still push out the necessary firmware when they are ready. You cannot miss an update.

Should you get the Preview for Windows Phone 8.1 Update? We tell you.



Seriously, I'm sticking with preview for developers permanently, what's life without risks right :-)!

Living on the edge I see - love that LOL! But @Theo_andravida is right, we also need Cyan for sure. But the article is very reassuring because it tell us we will get Cyan eventually when the bitlocker problem is resolved. So come on, bring out the Dev Prev Update next week! LOL!

me too, but mostly because I also have a Lumia 822 in addition to my Lumia 928.  So, if something goes wrong with my 928 when i update it, it still have my 822 to fall back on (at least until i reset my 928).

Me too. I reset my phone last week because it was ruining slow and I lost loads of games progress including some in app purchases so I will never reset again

You should just easily be able to restore apps and IAPs, so long as you use the same Microsoft account you had before the reset.

Many apps with IAPs already have a "restore purchases" button, and even if not: Just try making the same IAP again, it will be flagged as already purchased, and let you download it again for free.

If you wait without doing the hard reset to get cyan and then the preview for 8.1 you will be happy to see that the backup system is a way better it restore everything with all your previous settings for all apps.... The backup on DP take like 12megs on Cyan iv got 96megs !!!

I backed up and got everything back but I lost all my game progress on a lot of games one which I have spent money on. I tried clicking on the same in app purchase but it didn't work

Cyan is not available for my phone yet but I have 8.1 on DP. App and settings backed up fine I just lost all my progress. Was gutted coz I never lose it when my phone updates. I lost progress for 2020 my country, harmony isle, demon defense, tiny death star, airport city and adventure town (yes I like the boring city building ones lol) I had bought credits in my country but now I have lost the progress

Awh ok, i was talking after Cyan and official WP 8.1 installed if you have to reset your phone for some reason you will get back nearly everything, setting apps, password, saved games...etc On DP you get only the apps you have installed and your background pictures

I said that because the official 8.1 update is installed with Cyan update, i know that the backup thing has nothing to do with Cyan, everyone know this !!!

Developer Preview gives you the exact same build of 8.1 as Cyan does... Developer Preview /is/ the official version of WP8.1.

OS wise: There is zero difference between someone running 8.1 from the Developer Preview and someone who got it from Cyan.

Actually there is a difference because the DP version update 2 OS number is 8.10.1293.890 and the official OS number is 8.10.12397.895 !!

Latest DP build is 8.10.124000.899, so /technically/ it's slightly newer than the build being shipped with Cyan. But it's just very tiny, very much under-the-hood optimizations and improvements. No real difference in terms of user experience, at least that are noticeable.

Chill out peeps. I didn't mean to start an argument. I had everything set to backup but I think that it is the app developers decision whether they program it so that the progress

We weren't arguing to my knowledge. I was just trying to figure out what you were getting at, because data being backed up should incur literally no change between DP and Cyan.

So indeed it was likely just more app developers flipping the switch to "on" for app data backup.

The wording says "may" not that it will. It's more of a protection clause, not that they are necessarily worried. Having said that, I am not aware of anyone bricking their phones and not getting help.

Oh ok. I may take wp 8.1 in this week or next. Should i right then download DP and get update 1, is it recommended and safe? Or should i wait for it officially tocome out?

I mean, at this point just wait until it is announced and see what happens. Or you could do it now, it doesn't really matter, in the end we all end up in the same spot. Some just get their sooner than others ;)

Don't forget that there is also the nokia software recovery tool that you can use if things should go wrong. it will nicely figure out the latest official software for your phone and recover it to that. A pretty painless process I underwent with a 928 that I wanted to pass onto someone without developer preview.

GDR1 is the internal name. 'Windows Phone 8.1 Update' is the public name.

Note: Microsoft does not call it 'Update 1' as we do because it necessarily implies there is an 'Update 2' ;) That is a borderline announcement, so they just say 'Update' with no further promises.

I have not bricked my phone, but I will say that Nokia refused to service my phone with battery issues (which I had before 8.1) just because I was running the Dev Preview.

If you had issues with your battery then it was VERY dumb to not get that fixed before joining something that tells you that it might void your warranty.

I'm just stating my experience. I did it as I assumed the Battery Saver feature might actually help. Its not really that dumb, if I cared enough I would just use the recovery tool and get it fixed.

Sure, it would have been a nice plan to rty that out and if it didn't help then flash it back and ask for help. But you couldn't possibly expect them to fix the phone in less than an hour. So why even try to ask for help without even flashing it back? You story does not hold my friend.

Now that we have software from Nokia to help with bricked phones, I don't feel scared living on the edge. You should link to that program as well.

No, upgrading to WP 8.1 DP it doesn't void your warranty, cuz that is considered an official update from Microsoft. So, you are safe with that.

But Daniel I have a request. We, the normal mortal users, we write so many emails asking Samsung will they support their WP8 devices like ATIV S, ATIV SE, etc... but we haven't get an answer yet, or some people get the answer but in form like "We are not aware of that ... blah blah blah". Could you guys as a respective and well know web site, ask Samsung directly will they roll out their firmware for the WP8.1 so we who are still on WP8 GDR3 to know will we get the upgrade or not? Maybe they will answer you cuz your site is well known in those circles.

Thank you :)

Samsung, they only care about money, no appreciation in customers and on their support to help them, that is why microsoft is the future

Yeah, definitely, especially when they admitted to a faulty batch of S4 batteries and provided new, free batteries to anyone afflicted over the counter, no need to send your phone away. Such money whores they are.

My Lumia 720 (BRAZIL) got broke and I sent it to Nokia Care, they told that warranty fix was under Nokia approval (because screen was completely cracked) and I tought that they would deny it because it was running 8.1 DP, but they approved and they are now fixing it (they're even putting a new glass screen for free!) \o/

You know what is stupid about the hold. As WPCentral reported and as logic would dictate, the people who would actually have bit locker and be affected are a minority. So, the majority are being held back, because of the few. This would be ok and understandable if Nokia didn't have their recovery tool. Microsoft actually suggests to use this tool. So, why not let everyone who didn't have bit locker (which is the vast majority) get the update and let IT departments deal with this issue by turning off updates as a group policy or something like that? Either everyone on Preview needs to use the recovery tool to get on Update 1, or a handful who have bit locker do to fix a bricked phone.

Technically no one has to use the recovery tool, as people could just wait.

It is unfortunate about the minority blocking the majority thing, but AFAIK there is no way to selectively block based on BitLocker enrollment alone. All the Preview program does is tell the phone's OS "Look here at this URL, not the regular one for an update".

But since the phones are set to work on company policies once paired with a corporate account, IT departments could just disable updates, could they not?

I think this is a reaction to their target audience. Microsoft caters to corporate environments and wants to keep those businesses that use WP happy. They need that market badly to succeed in the US.

And I know we don't have to use it, but it's just seems knee-jerk that, since there is a solution for any phone that does get bricked to be un-bricked, it was stopped in the first place. Or at least resumed by now, even with the issue persisting (which could be patched later).
I know it's not a huge deal, but it is a tad frustrating when there are fixes and a brick doesn't mean the end of the world.

Seems like the installer itself could detect BitLocker and refuse to continue. But there must be a technical reason why it doesn't, like the need to roll out a third update that everyone would have to download.

Daniel, I need your help. I have a different problem! When I got Amber OTA I updated to gdr3 with DP then to 8.1 with DP too! Now when I go to "extras + info" it says "Amber". The black update is now available for my phone but when I check for updates it say is already up to date with Amber! Now, my volume buttons stopped working and I think it's cause this whole mess! Please what should I do! Help me! Thank you anyway!!!

Maybe it will work when you update to Cyan?

Otherwise you might have to use the Nokia software to roll back to 8.0 which should give you black (hopefully).

I had the same issue, tried to return it to 8.0, didn't work. I sent it to my carrier so they could solve it, they returned it to me running Lumia Black. It was, however, back on 8.0, but after an hour I had it on 8.1. They had no trouble with the phone running Preview for Developers or being Developer Unlocked and did it all for free, even if they said they'd charge me about 3.500 Chilean pesos (like 7 dollars). Good luck!

I think the bitlocker issue is a bigger one. Everything was perfect on my htc 8x until I had to activate it because of my corporate email policy and then suddenly wp8.1 update build 12400 bricked my phone. It was very strange though the update went without issues but after the first restart I got a blue screen error. I could not find a solution so far and it seems I have to go to the service center.

Just want sure with all the news lately if I had just managed to overlook it. Hahah. Anyway, thanks for all you guys do! Locked out of cyan anyway with dp, so its the waiting game for me! :)

I was on the phone a few days ago with an AT&T support rep who said 920 is slated to get the update this month (August).

I have read everything on this and still can't figure out what the hell is going on.  So I'm just going to sit back and enjoy my DP and wait for the big official rollout of Update (aka Update 1, not Update 2).

Some users with BitLocker on their Lumias got their phones bricked by the 8.1+Cyan update. Because of this, Microsoft decided that until they solve the issue, people whose phones can get the Cyan update but are enrolled on the Preview for Developers program won't get Cyan. So, they have recommended people who want Cyan right now and whose carriers have already released this firmware update to downgrade to 8.0 before they get Cyan. But you can still wait for the issue to be solved and keep in 8.1 Dev. Preview until Microsoft lifts the "ban" for Cyan.

Thank you for writing this article. I repair computers for a living, and have found it hard to explain to my clients what's going on in a way that explains, without diving into incomprehensible technical language. I am amazed at what constitutes "incomprehensible technical language". It doesn't take much...still learning after 2.5 years...

I downgraded to 8.0 based on the other articles regarding DP, Bitlocker and such, but now am confident that everything will work in the end. So, I'm upgrading this evening back to 8.1 DP. I've got a Lumia 928, so it'll be a while for Big Red (Verizon) to get official 8.1/Cyan out; I can wait.

Suggestion: in light of the massive user confusion between OS (8.1) and firmware (Cyan), it might be a good idea to say "Cyan firmware", so some might see the difference. Just a thought.

Daniel - How can Cyan be pushed to Dev Preview 8.1 Update 1 , as there is higher OS version now , i know they work independently firmware vs OS ( usually nokia firmware includes OS ) .

Scenario - User updates Dev Preview 8.1 Update 1 ( using live folders / sms / new features ).

Update notification comes few days later ( Cyan ) , it gets rid of  live folders/ new features etc.

May be i am confused. !

Don't think about it too hard. Just accept it on faith ;)

But if you want to know: The firmware gets applied to devices with a certain OS build or higher. It is not targeted to one specific build number. Cyan is on devices with OS builds 12359, 12397 and 12400.

So if OS is build 12359 or >, move on to Cyan. (Assuming Microsoft is not blocking you)

I'm confused too, it seemed to be a kinda downgrade from Update 1" to cyan.
But lets see if Microsoft will fiX the bit locker thingy before pushing out Update 1.

Cyan is firmware, not a WP version. It's an upgrade from Black, not WP 8.0,  8.1, or 8.1 update 1. To draw a flawed but adequate analogy for the Cyan/ 8.1 update situation, the firmware is like your basement and the OS is like your house. 8.1 update 1 is adding another story to your house, while Cyan is installing a gym in your basement. They have nothing to do with each other and are just two different upgrades. In general there's more of a relationship between firmware and OS, but for this case it's that simple.

I do hope they fix the bitlocker thing soon, but it doesn't matter if it's before or after update 1.

You are confused. As you say, yes Cyan is independent of the OS (just distributed at the same time officially). So if you move to PfD 8.1 Update, you will get Cyan when it's released for your phone later on (once the BitLocker update bug is fixed).

In the scenario you describe, you will not lose the Update features.

It will not because when your phone notifies you about the update, it will show you TWO different packages: The Windows Phone, or Microsoft Update (xxxxx), which is the OS update, and then the Nokia update xxxxx, which is the firmware update.
The ROLLOUT process (usually) includes both. The packages come together, but independently. Do you get it now?

Scenario 4:
You own a Lumia 810 still running the Amber update and are keeping your phone up to date through the Dev Preview.

Bottom line:
I hate T-Mobile.

My condolences. At least you got Amber before they stopped updating; that added more interesting stuff than Black or Cyan, such as Glance.

And in articles to come about updates to remaining phone people will always ask whether downgrade or no and when will update come for my phone?
just wait,relax,chill,like this article said be patient or downgrade and do it ,ezpz

Pretty straightforward. I think we needed an article like this to appease the panic and bring some clarity. Thank you so much. Still, I would love it if Microsoft would share the progress of the fix or give at least a ballpark ETA. ;)

My NFC stopped working after the last update which Microsoft pulled. Hope it's a software and will get fixed, bit could also be just the hardware broke.

HTC confirmed it a couple of times ... they are probably holding it until the new phone comes out ... all OEMs do that.

I still want to know why some HTC phones won't find the update at all...my other 8XT will not update to 8.1 DP...been that way for 6 weeks! and yes...I'm signed up, app installed, enabled, etc...it will not find the update...and I'm not alone.

On my Lumia 925... Downgraded got cyan upgraded for 8.1 installed developer preview now waiting on 8.1 update 1 .. Good to go. Took a while. I'd like to sign into my phone and everything just reinstall without me having to go through it. Even Skype I had to sign in. But its my phone and I signed in with my Microsoft credentials already...

Simple, clear and well written. There is a lot of confusion and disinformation about the Cyan/Preview for Developers theme, that this kind of articles are very welcome and helpful. Gracias.

Good article explains the situation very well.

Now just wait.

In a couple of hours we're going to get a whole lot of nonsense posted in the comments because certain people need to display their self absorbed incompetance.

Let's further assume I have a Lumia for which Cyan is not available yet (e.g. L920) and I have DP8.1 installed for which I'd be able to update to Update 1 next week.

If I stay on DP I would have to wait for the fix until I can get Cyan

If Cyan is released first for the L920 and there is still no ETA for the fix I could downgrade to 8.0, upgrade to 8.1, get Cyan, and install DP and get 8.1 Update 1 on DP - and I don't have to wait. The likelihood this happens is a wild guess of course.

Yes, exactly. I'm on an ATT 920 (only vendor in the US) and on devpreview too. ATT hasn't released cyan yet, so in my case, there's zero point in restoring, downgrading, updating, since cyan won't be available. People who have cyan available can do the whole process and then get all updates... or just wait a bit longer for the bitlocker bug to be fixed and then get everything a bit later.

Personally, I'll wait. I'll get wp8.1 update 1 next week and whenever cyan is available it'll be pushed OTA to my phone. None of these updates are huge (well, those IE changes in update 1 are kind of a big deal to me) so waiting a bit longer isn't hard.

Yeah IE is all I care about in Update 1. I don't care about the folders since I haven't changed my Start screen since 8.0. Heck, I haven't taken advantage of the wallpapers in 8.1 and I don't plan to either.

I was bored last night, so I rolled back my Lumia 925 (ATT) to 8 and received the updates.  Now on 8.1 with Cyan.  I guess Cyan means different things to different models.   It is time consuming as Daniel said, and it took a lot longer than I wanted to mess with (do not start this process at 11 pm!).  925 is running in tip top shape!  Now I will re install the Dev Preview app to see what else come! 

Was hoping to see the brightness slider,  but it did not come to the 925; still have low, medium and high for brightness. 

Daniel, just out of curiosity, do you know if this is a bug present in current official Windows Phone 8.1 phones (with BitLocker) as well, so that it would cause problems if they get the Update (either through PfD program or later through official channels)? Or is it ONLY an issue with the Cyan update and not caused at all by the actual official Windows Phone 8.1 OS install?

If it's an issue with WP8.1, and not just the PfD or Cyan update process, I would assume Microsoft will be even more diligent about getting a fix out, which would be good for everyone and hopefully mean the fix is included in WP 8.1 Update itself (so we won't have to rollback to 8.0, and also not have to wait too much longer).

The problem seems to be how Cyan handles the devpreview 8.1 updating process. For all we know, Microsoft could have fixed the bug in update 1 and so once devpreview users update to it all we'll have to do is wait for our carriers to make Cyan available.

Some people are amazing ,after every article they ask when will it come for my phone or why can't Microsoft fix issues and let DP users get it,have people forgotten that developer preview is really a beta,despite how good it works,it's all really beta and you surely didn't read anything before you installed about it saying that.i have 1020 unlocked Singapore variant running DP8.1 ,can easily do backup,downgrade & get cyan,or just wait it out, there has even been an app developed an you can pin on start screen to see when update is available,why always come and rant and question? It's under testing and will be rolled out,everyone just seems to want everything NOW .it doesn't happen that way

Jesus Christ I've lost count of how many times I've said this: dev preview is NOT A BETA. We got RTM software. Any 8.1 builds after that are post-RTM.


TL;DR: rollinadice is basically right but used the wrong word.

There's this big debate about whether the DP is beta and it's mostly because some people use the term beta loosely.

It is a simple fact that the 8.1 DP was never a "beta". It was RTM, which is a label given by MS to a certain stable build. Before that we can assume they internally had builds labeled as beta and RC. But no build released under the DP was beta or even RC. This is not disputable as those are just names MS gives them. It doesn't mean the build would never get an update. If that's your definition of beta, then 7.8 is the only version of WP out of beta.

However, it was a prerelease build because there were more updates before GA, and more importantly, it wasn't released the normal way, packaged with the firmware. This theoretically shouldn't have mattered, but for bitlocker users it did. The nonstandard upgrade path wasn't sufficiently tested, and so the use-at-your-own -risk nature of the dev preview did come into effect in this case.

I have Amber + PFD of Black (GDR2) + PFD 8.1 so at this point my phone is full of Previews and one more it wont be a problem for me xD I'm not that patient for wait official releases of my carrier :P

Thank you Daniel. I am on DP 8.1 L920 and was unsure what to do as far as 8.1 update and no cyan yet. This makes it crystal clear.

Nobody likes a phone dialler without cursor.

Speaking of 3310, it also has cursor in phone dialer, but WP doesn't http://windowsphone.uservoice.com/forums/101801-feature-suggestions/suggestions/2294827-cursor-in-phone-dialler-to-allow-editing

iOS made this blunder for the first time in the history of phones. Android has it, even Window Mobile had it.

This is what happened on this account:

- iOS dropped it for the first time in the name of their uniqueness craze: only fanboys know how to defend it by telling you why you don't need it

- Android copied everything from iOS except for this, which they copied from Windows Mobile: their users are happy with sanity

- Windows Phone copied iOS: fanboys copied their fanboys' argument


They just bit the wrong part of Apple there, instead of trusting their own sanity and paying attention to detail that what the heck they are about to do..

Which is fine too. The take away though is this: Whatever you do, at some point, we will all be on the same OS build and firmware. It's just how you get there. There really is zero risk here.

I had developer view installed, then the cyan update came available for my att 1520. I did downgrade and do the necessary steps to install and honestly I'm glad I did. The firmware has made my phone run even better. Before the cyan update there were screen flickering issues and slider volume errors. Along with minor other tweaky issues. After the cyan update my phone head never run smoother..... Yeah it takes a little time to reinstall apps from the SD card because I save everything to my SD card and you can't use the apps on the SD card until you redownload them all. But all said and done my phone is absolutely amazing right now. and after all this, I need not to worry about the hold on cyan or other updates.

Yup, and I agree. This is something to consider if we tell you Cyan is available right now for your phone. But I do not recommend people do it if it is not yet available. No point just yet.

Daniel - you should make a brief post stating that dev preview is NOT a beta. People keep thinking it is and not undesrtanding that we received the RTM version and anything after that has been post-rtm.

It would be a good idea to make a post about it if only to simply educate all our forum users and posters.

Thank  you for clarifying this topic.  I don't understand the confusion that is evident after reading this post.  Nice work.

So yes I should. It's a good thing that the Preview for Developers program exists, but the lack of optimized firmware in these releases drains the battery a lot faster than with finalized software, says my 620.

Would like to see a feature that would let you pin website shortcuts into a folder. I have several websites pinned to the start screen and placing them all in one folder would clean things up a bit. I uses UC Browser now but...

Here is my concern - after installing 8.1 there have been a few issues with my icon like the camera taking awhile to load and the screen taking time to turn on. Additionally picture quality seems worse. I assume that the cyan update will fix this but I'm concerned I will get cyan, it will optimize my icon for the 8.1 update, but then ill get 8.1 update 1 and I will no longer be optimized

The Cyan update has definitely fixed picture quality, but the launch speed is still an issue. I can't say it was ever that fast for me, though, using Nokia Camera on my 1520. If I switch my default to the Microsoft Camera, it launches almost instantly, which tells me the problem is with the app itself. Turning Living Images off helps, but there is still a delay. I can't help but share your concern about losing the Lumia Cyan optimizations if I upgrade to Update 1. I tried to ask Joe Belfiore about this, but he never responds to my questions on Twitter.

That eased my mind on what will in the unity case the fix came before the update. As long as I am in the preview program, I will receive the update. The only people affected immediately are those using bit locker. My question in the article is the use of the word "many." As a % how many were affected by this bug?

I do not endorse using preview for developers. Upgrading my Lumia 822 to 8.1 before Cyan came out resulted in my camera not working at all, GPS inaccuracy/infrequent updates, and song info not showing when playing in my car. I've had to go without a phone camera for over a month now. Does anyone know if there will be a Lumia firmware update alongside 8.1 GDR1 or if Cyan takes care of it as well? I will be dropping out of Preview for Developers if a firmware update is needed for every OS update.

The Lumia 822 seems to have more problems than those devices. I have had so many problems with my 822 and all my friends with the 920 haven't had any problems. The only problem I saw on a 920 wasn't a software issue. It was his screen that cracked.

Several users on XDA recommends on avoiding the 8.1 Update for ALL CDMA devices, whether you are on Verizon, Sprint, U.S. Cellular, or any TD-SCDMA carrier in China. There are miscellaneous problems resetting your phone making it an extremely sub-optimal experience. I guess there still is even though its now back to the RTM build. I know it seems to work okay on the Icon and the 928, but I'm still avoiding it for the ATIV SE as that's my main driver until I can figure out how I can provide the firstInteropUnlock on it.... The Odyssey that I used seems to be taking it better since I reset it more recently (my last reset was during a preview built and not the RTM build we now have). I'd make the jump if there were ROMs available for the ATIV SE, just incase something goes wrong.

Very clear...thank you for this! Looks like I don't have to wait after all and will just update to Update 1. If none else, I can do the lengthy process and be okay with the Software Restore Tool
