T-Mobile evidently passed on the Nokia Lumia 710 7.8 OS update

When it comes to the Windows Phone 7.8 OS update, the one that brings you those fancy new Live Tiles, there are those who are officially getting it and those who have to DIY.

Unfortunately for Nokia Lumia 710 owners on T-Mobile, you may have just been kicked to the second category.

A reader of the site passed on an email from Nokia themselves and it doesn’t come off as customer-service fluff, especially with the news it contains. The email states quite succinctly that the US T-Mobile Lumia 710 will not be getting the 7.8 update because the carrier chose to pass on it:

"In response to your concern, we understand that you want to confirm if the Windows Phone 7.8 will be available for Nokia Lumia 710 from T-Mobile. We are sorry to inform you that there are a small number of operators that have chosen not to offer the update to their users.It is important to recognize that this decision was made solely by the operator and these include the T-Mobile network in the United States."

That’s certainly a bit of a kick from T-Mobile, though we suppose with the carrier cost of testing the update and the perceived benefit, they decided against it. And although we don’t have a similar confirmation for the HTC Radar, we have a feeling that device will suffer the same fate.

All is not lost though for those with either device as they can opt to manually install the update via CAB files. Though a tad tricky, the update will successfully bump the OS up through Tango to Windows Phone 7.8, giving some solace to those in this position.

T-Mobile, for the record, has been silent on the matter remaining non-committal in their support forums (opens in new tab).

Thanks, John L., for the tip!

  • The 8X?
  • Meant Radar. Fixed.
  • I got confused for a sec, too many devices! Lol
  •   Love my job, since I've been bringing in $5600… I sit at home, music playing while I work in front of my new iMac that I got now that I'm making it online(Click on menu Home)
  • Can someone please DELETE all SPAM comments below all articles on Wpcentral site of this MORON? Thanks :)
  • Daniel any word on update coming and if u don't know could u use your contacts and find out please WP buddy :)
  • When's the update out for HTC radar c110e
  • For those who want to manually update their TMobile Radar 4g, I have created a zip with all files needed and a very simple to use walkthrough. I, and multiple users in a previous post have all used it with success so I figure I'd repost it for those who want it:
    If you have a Tmobile HTC Radar 4G, currently on mango (8107) with 5 language files (Deutsch, English, Espanol, Francais, and Italiano) under Settings->region+language->Display language. The following file will completely walk you through updating to WP7.8, everything included. I have done this on my own phone.
    If you get a COM error when launching WP7 Update Cab Sender,
    X86 install this -
    X64 install this -
  • Just an FYI, technically these files and walkthrough will work for any phone currently on 8107 that have the 5 (and only the 5!) languages that I listed. Doesn't have to be Tmobile or a Radar. But you do have to be on 8107 and have only those 5 languages.
  • I just wanted to say thank you for posting this. I can confirm it works and am so happy I got my radar updated..Thanks again!
  • Is Verizon going to update Trophy?
  • Probably not, if they want to sell the Windows Phone 8 line... =/
  • You would think that but they still haven't pulled the Trophy from the line up. Who would buy it I have no clue as its 179.99 on contract.
  • So to be clear, if you have any Windows Phone 7.x on T-mobile in the US, you will not get the 7.8 upgrade? So us with DVPs on TMobile are out of luck as well?
  • The 710 reportedly sold very well on T-Mobile whereas the DVP was not ever an "official" device, so that would be my guess. Sorry :-/
  • True. Just want to clarify as it read as though no windows phones would be getting the update on Tmobile. I guess I know why the cable trick didn't work now. I also apparently know what I'll be doing this weekend #WPHacker app.
  • I was wondering why the cable trick wasn't working for me, too.  I tried about 20 times last night.  *sigh*  Thanks a whole lot, T-Mobile.  :(
    Looks like 1 year later with the Lumia 710 on T-Mobile, we're all put out to join our many, many Android brethren.  What a disgrace.
  • Unlocking the phone may work. But I can't confirm whether that takes TMo out of the picture, and Microsoft picks up from there. I was going to try with my HD7.
  • Had TMobile unlock my HD7 a while ago, tried the cable trick with no success.
  • I have the dvp too!
  • When trying to run the seveneighter.exe I get the error message that this is not a valid Win32 application and it won't run. Any ideas?
  • You are probably running the wrong file. If you are using x64 windows run the executable in the x64 folder. for 32bit Windows use the one in the x86 folder. If this does not help then I don't know.
  • My DVP upgraded to 7.8. I did not have my SIM card in the handset when I connect to computer. I don't know if made the difference. 
  • The tool only runs on Windows 7, not XP or Windows 8. Just updated and it went flawlessly. My DVP is like a new phone. Much zippier and the tile resizing is great. If you look hard enough there are little changes sprinkled throughout. Now time watch some football.
    There is an excellent walkthrough of the process for any noob attempting to use the update tool at of all places a site called the droidguy. Enjoy.
  • I update my wife's Lumia 710 yesterday with the WPHacker app. Also my LG Optimus 7 (E900h) with the same app. #justsaying
  • Is it tmobile branded NL710?
  • It worked for my Nokia Lumia 710 locked to T-Mobile US, so yes. The update works. Just be aware of the risks of bricking your phone, since seveneighter does use the same method as the CAB method. Since Zune uses this process as well, that means that no personal data is erased. 
    However, I've already received the same notification from version 7.5 (Tango or Mango) saying that I need to update my phone on the Nokia Bluetooth Sahre and Ringtone Maker App. The tile animation when you click on one is slower, so be sure to get acquainted with it. There's no lockscreen music control and as far as I can tell, no option to set either Google or Bing as default search provider. Plus, seveneighter ONLY installs the 7.8 OS, with no hint of new Nokia firmware, so the two mentioned Nokia apps will not work.
  • Just did it to my T-Mobile locked Nokia Lumia 710, it worked flawlessly!! Thank you!!
  • So wait, do all Nokia apps not work? E.g, Nokia Drive, Maps, etc.
  • What wphack app more detail please
  • The "wphack app" you mention is actually called seveneighter, the program you use to force update your phone if the Zune cable trick doesn't work and if you're too afraid of bricking your phone with the manual .CAB method.
    Just be aware that seveneighter doesn't upgrade the firmware, just the OS, so don't be surprised if the features you receive are only on the cosmetic side.
  • Expected I don't know why Microsoft gave carriers the option. Wasn't this supposed to be a mandatory update?
  • Not a mandatory upddate because no critical flaws were addressed. Just the look.
  • Well I don't know, me personally I just feel that Microsoft shouldn't have mentioned this update unless all carriers had agreed to commit to it.
  • well that's horseshit too because the disappearing keyboard WAS a critical flaw and ATT passed on that.
    Microsoft has ceded ALL of the control of updates to the carriers, and that is one thing that will cause this platform to fail. 
  • Aside from apple, no company can wield such power. If they want to sell phones, they have to give this sort of power to the carriers. Carriers (especially in the US, not entirely sure on the specifics of other countries) can make or break a device and MS is at their mercy.
  • It would be nice if, rather than making empty promises about updates, Microsoft focused on things they can control.  How about offering at least one carrier unlocked phone through the Microsoft Store as a flagship that would be guaranteed to receive updates?  Heck, maybe this could be a niche for a MS Surface phone that wouldn't step too much on their partners' toes.  It's not like this is a radical idea.  Google has their Nexus phone (of which the latest model appears to be selling well) and Apple sells unlocked iPhones through their store.
  • ^ This NEEDS to happen.
  • It's really easy to blame MS as the company at fault when tmobile is clearly the culprit. MS never promised/guaranteed anyone specific  an update, they merely said the update would be available for all wp7 devices. They still have to go through the carriers who test it on their networks before release. Apple sells unlocked phones at their store at least a few months after release (the 5 didnt start till december), and I can get the lumia 900 fully unlocked easily. This is the first gen of WP8 so we have to wait at least for the second gen before we can get a flagship first gen fully unlocked phone (the US is strange on these things). You can always order the Rogers Lumia 920 from Canada and it will work on both Tmobile and ATT. Also, the nexus came out many years after android did, and it was after they were pretty established. Our platform is a baby and still needs to take some ground before doing anything like this. I really hope thats what the surface phone will be, but only time will tell.
  • I completely agree that in this particular case, the blame lies squarely with T-Mobile. And in any case where a Windows Phone update is held back either due to a carrier or handset maker, those parties should be held responsible. That's reality.
    However, Microsoft is ultimately responsible for the strategy they choose in dealing with the reality they face, and part of that is how they address the update situation and how they communicate that to their end users.  Microsoft sold WP 7 as being a sort.of best of both worlds when it was launched.  Unlike Apple, it would be a platform available from multiple handset makers and would allow for more diverse hardware.  However, unlike Android, the platform would be more tightly controlled and carriers would have limited ability to hold back updates, so fragmentation wouldn't be a concern.  This was Microsoft's message - or at least it was the message they allowed to be reported. That set the expectations.
    When WP8 was launched, MS again discussed the update situation, including how they would put a program in place to allow end users to get updates (at their own risk) even if the carriers wouldn't push them.  I don't think anyone has heard anything more about that, though, which is strange to me. If the details were set, why isn't that program already live? And if the details aren't set, why not keep it quiet until it's ready? Is there some sort of deep miscommunication going on internally, or some sort of bizarre self-delusion among WP management?
    If seems that getting timely updates out is important enough to MS that they feel compelled to talk about their planned approaches at the platform launches.  Given that they appear to have limited clout with the carriers, their plan B was apparently the enthusiast program for WP8, which so far isn't live.  Has that run into a roadblock? If so, what's their plan C? What are their options for limiting interference from the carriers (and also failings of handset makers, like the 7.8 update situation with LG).
  • The only reality is that in the US, this is the only way to do it if you want carriers to sell your phones (unless of course you are apple). Obviously we already have way more hardware diversity than apple, and I firmly believe we are miles ahead of android. MS has released the update for all phones, as have most OEMs. This is exclusivly the fault of carriers. On android, oems dont even release updates. Also, throughout most of the world, updates arent a problem. Again, MS didnt promise any of this, this is what they set out to do and are mostly successful. We always have cab files to update our phones, but wp8 has only launched in november. I too heard about the program but all things take time. If they didnt, we would have a notification center already and google wouldnt need to extend eas support. But if they don't say anything, people again get impatient and say exactly what you said and how MS doesn't want to support their customers. I think this was the best of 2 crappy situations that they are stuck in being a newcomer with almost no mindshare. The DPV and LG phones have to use the cab method, which seems suspiciously easy to utilize. We dont know everything, but I'd say we're doing way better than android.
  • Yes, I have agreed with you that any specific case of a Windows phone not getting updated is the fault of the carrier or handset maker.  But Microsoft is still the one that has been responsible for raising the expectations of people with so far unwarranted happy talk about upgrade potential. (As far as I can tell, Google generally hasn't tried to spin the upgrade situation with Android much.  As a result, people who care about updates on the Android side don't seem to bear any particular ill will towards Google when their phones aren't updated, but rather focus on the carriers and handset makers.)
    So the reality is that essentially any Windows Phones on US carriers - old or current - may have their SUPPORTED upgrade paths terminated at any time by the 'middlemen' between MS and the end user. This is a problem for the platform. Android is absolutely in the same boat.  And yes, having rooted and installed custom ROMs on Android phones, hacking an update to a Windows Phone is easier.  But it's still an unsupported (void the warranty, potentially brick the phone) hack that won't include things like firmware updates that may be necessary to fix some issues or take full advantage of new features. 
    But as much as I dislike Android in many respects, I think Google has come up with a pretty good response to the reality of the situation through their Nexus phones.  Enthusiasts who want to be reasonably assured of getting updates without carrier interference or hacking can pick up one of those, while the carriers can keep control of the mass market handsets.  And those that want to root and hack their phones can keep doing that.  If Microsoft can get the WP8 enthusiast program going, and if it works like it should, then I can see that as a superior approach.  But I'm not encouraged by their track record.
  • You say you agree but you keep going back to MS's track record. Again, the US isn't the only market in the world; it is an extremely strange one though. What MS said is true most places in the world. Most people outside the US are getting the updates. The market here gives an extreme amount of power to the carriers and thats a truth MS has to deal with. I guess what I'm trying to imply is that MS has no say in the matter, lest they lose the support of the carriers. I'm not exactly sure what you mean by raising the expectations of people or where you are getting info about what they are doing. They said the update would be made available for each phone to the OEMs and it is. They never mentioned that they could get around the middle man because that is unrealistic. While it is true that talk and rumors build up expectations based on one or two sentences from a company, but that again is no fault of MS.
  • Amen to the disappearing keyboard. Sprint never gave out the update either. Luckily my HTC Arrive has a physical keyboard and I can slide it out whenever it gets too annoying.
  • Except that on my Arrive even the physical keyboard suffers the issue. Thats part of the reason I just did the manual update all the way through WP7.8. It really wasn't hard at all.
  • All this yada yada about Microsoft phone updates being nothing like android was all a lot of crap huh?
  • I don't think anyone ever said that. What IS clear is that Microsoft is positioned, as always, between two the two extremes of Apple and Android. Sure, our OS updates are not as consistent and universal as Apple but they are far, far better than what is available on Android.  It's nothing to celebrate but nothing to mourn either, imo.
  • I don't know never did get an update notification on Gen 1 focus since Mango
  • No one did. 
  • Just update it via the cab method, i did it for my dad's phone and he is loving the new look
  • actually with ICS and Jellybean, Android is making Windows Phone look more inconsistent.
  • No u r wrong.... Actualy google is an open platform
    so they even dont know which phone will get ics or jb fm gingerb.... But ms is well organized... So they can deliver an update to all of their phone successfully.... Just like apple... But they cannot interfere in carriers policies. Ie they cannot force...
  • Nexus*
  • I'm guessing the asterisk is to indicate the unlocked GSM version?  I recall lots of people feeling cheated that their Verizon GNex didn't get the Jelly Bean update at the same time as the unlocked gsm GNex. 
  • Why can't Microsoft just post the OS update in the marketplace? Bypass these idiot carriers and let us download it.
  • Because technically the carrier sold you the phone and in a lot of cases, subsidized it. Carriers want to know what is running on their network--it is theirs, after all. So they tend to have strict policies about software updates. Not saying it's fair or right but that's why.
  • Thanks Danny.
  • All this testing for eash network is a toss I have used my unlocked phone in Australia,Most of Asia an Europe and have never had a problem in any country with getting a sim card to work.
    Microsoft should give everyone an easy way to update manually if we want. ( at our own risk of corse).
  • They say that is coming
  • I agree. Carriers have too much control, especially in the US. If I get HPI on a car, the financing company doesn't dictate what I listen to on the radio. If I get a mortgage, my bank doesn't dictate how I decorate my home. There's absolutely no reason why the carrier should control the user experience of the device. They provide the network, only.
  • Really doesn't make sense in this case as most of the upgrade is purely cosmetic, at least according to WPcentral. This may be the reason I need to finally leave T-mobile.
  • +1
  • MS is in no position to make demands of the carriers. I'd imagine they are trying to negotiate a better method, but there's only so much they can do while demand for WP is so low.
  • You people are asleep at the wheel. Did you not see Microsoft and Nokia's end of quarter earnings a few days ago. They are raking in billions off you. And TMO aka Deutsche Telekom, 130 million customers worldwide. You trying to spend all your money; they are trying rake in all your money. Stepping on your toes along the way.
  • Off topic.. the photo shows Telcel carrier, that is for México. Are you (Daniel) on México? I am. Or maybe an internet picture..
  • Nah, had flashed the 710 with a Telcel ROM, that's all.
  • I am on Telcel, Daniel and getting the update might indeed be wishfull thinking ....they were not stellar with Mango update and had to force load it.
  • I wish they would at least give their customers payment options...I would be just fine sending them more money to post updates to my device. Aren't they phasing out device subsidies? =[
  • i spoke to a T-mobile rep the other day and she states that T-mobile had no idea there was even an update to begin with and there was no information to be given out to consumers at that time. Such a big let down, since it was a Lumia device. As soon as i saw this article, i tried the manual installation of the CAB files with the Windows phone hacker tool, and so far it works great. No problems to report at this time. 
  • Tmobile reps lie and/or are a bunch of idiots. I had 3 different reps all tell me they had no idea what mango was. 1 even told me that windows phone 8 was coming at the end of the year, which was back in 2011, which obviously didn't happen.
  • I spoke with a dummy similar to that and then asked to be transfered to tech support, where the guy told me that the update is in the pipe, but there's no firm date of release. I wonder, if he just said it so I would leave him alone
  • That's probably it. "in the pipe" in not a good enough timeframe, but luckily I already used the tool to get it.
  • ROM is available so it's not a big deal IMO. Truth is most average users don't know about 7.8 and don't care as long as their 7.5 is working great, which seems to be the case.
  • I just updated a lumia 710 today using the winphone hacker app. Also updated my HD7 yesterday. both are solid.
  • My HD7 is like a new phone.
  • Need to use that this weekend. Any tricks or info on using it?
  • It's easy. Follow the link in yesterday's article to download the app and run it. You probably need Zune and Windows Phone Support Tool. The app will ask you to install them if you don't have it. For my Focus with 7720 build, it took at least 6 or 7 updates to arrive at the final version 8858. Some updates cause phone to take long time to reboot. Be patient. And make sure to check off the launguages you need include when you run the app. It took good 30 minutes or more to complete for me.
  • When trying to run the seveneighter.exe I get the message that it s not a valid Win32 application. Any ideas?
  • Looks like it will only run under Windows 7 not XP or Win8.
  • Mine worked and I'm using Windows 8.  Did you install the Windows Phone support tool specifically for your processor type? (i.e. x64 or x86).
  • Updates are a carriers arch enemy, they want people to buy new devices, not update the ones they already have, Orange UK are a nightmare for updates, i dare say that if my 920 wasnt so new then i probably wouldnt have got portico, manage to force the update on my sons 710 but my daughters omina 7 is still on 7740 and just refuses to be forced, look like i might have to do a manual update (or debrand/unlock it)
  • Curiously T-Mobile Deutschland had not released the 7.8 on any devices either. I asked today (regarding a Lumia800) and they said this:
    "das Update ist für das Windows Phone 7 noch nicht verfügbar. In Kürze wird dieses aber auch hierfür zur Verfügung stehen. Sie werden damit alle Win8 Funktionen nutzen können." 
    Quick translation: the update for WP7 isn't available yet. Soon it will also be available. You'll then be able to use all functions of Win8 (which I think they meant WP8. While obviously by "WP8 functions" they mean resizable tiles, I wonder if T-Mobile added anything extra do their 7.8 update. Anyway, I tried the cable trick and the most curious thing happened: an update shows, from Nokia. It bumps the Firmware to 8858, the OS version remains the 8779 and  the software still shows "7.5" and keeps everything as it was. The update that shows has this log:
    - fixes an issue with app purchases in some regions
    - Changes default sync times for email 
  • The wphacker tool doesn't delete everything on the phone correct?
  • It deletes nothing. Its like doing the update through Zune. Except you may have to run it 3-5 times.
  • Thanks! Trying to convince my roommate to let me flash her 710
  • Total BS
  • Better off doing what I did and use the windows phone hacker tool. Running 7.8 since yesterday on my hd7 that tmo/htc/ms has decided to shaft us still using this device.
  • When you flashed it, did it erase everything on your phone?
  • no it doesnt. Not one thing was removed. Even my opened ie web pages were still opened after i update it. :D
  • Same here, can't count on T-mobile or HTC, so I used wphacker to update my wife HD7 phone last night.  Everything went fine, and her phone is up to 7.8 now.
  • The most pecuiliar thing happened to my Lumia 710. When I plugged it in to Zune, it showed another update, but when it finished, it reverted back to WP 7.5 Tango. I was mad when it happened. 
    Anyway, running the tool now. I'll update when it finishes.
    Went through 4 updates before hitting Windows Phone 7.8. 
    Somehow, the bluetooth share app doesn't work anymore. There's no aforementioned option to set Google or Bing as default search provider.  Turns out that you NEED the new Nokia Firmware released for Windows Phone 7.8 to use Bluetooth Share and Ringtone Maker, as well as have the option to change search providers (Bing or Google)
  • I updated my T-mobile  Nokia 710 using the simplified tool. I'm unable to download the Bluetooth Share but the Ringtone Maker works just fine.  I installed it today so you may try to see if you can get the Ringtone Maker.  I can't see any reason why the Ringtone Maker would require updated OS.
    The Bluetooth Share shows only 7.5 is required but somehow it would not allow me to download.  As to the search provider, it doesn't really matter that much to me at least  since I have Google Search installed.
  • Guys, what is WPHacker app ? Is it safe to use ?
  • Check this post:
    Good luck. 
  • Updated my US T-Mobile Lumia 710. Thank you.
  • What languages did you use for the US?  I saw I have 3 in display language, but a lot more inregion format that are way more than the language selection in the update solution.
  • You just need what's in display language list.
  • what lanugages did you select?  I only have 3 in language format, but a lot more in language region than are available in the selection of the update solution.
  • And this is where not having a contract pays off. T-Mobile just lost me as a customer. That's just a scumbag move.
    It is so entrirely easy to gain followers for life. Just treat people fairly. So incredibly simple.
  • Did T-Mobile deliver the Tango update for the 710? If not, how are they allowed to skip this one if carriers can only skip one?
  • T-Mo USA did deliver Tango to the Lumia 710.
  • Why yes, they did roll out the Tango update. The only thing was that a few users didn't get it until 3 months later.
    Anyway, T-Mobile is foolish to use their "skip one update" opportunity, due to the fact that many people have already left the 4th biggest US carrier and are moving to Verizon, AT&T, and even Sprint, the three offering LTE but only one offering unlimited data plans but spotty reception.  If they continue down this path, they will eventually lose many users to the point where big magenta has to call it quits.
  • In actually tmobile is launching LTE this year with so far two cities that has lte
  • No surprise here by mobile blocking the 710 update to 7.8. I had a C7 astound when they blocked Nokia belle update...glad I switched over to att and upgraded to the 920! Love this phone!
  • Have Microsoft even announced this update? There is nothing about it on their official Windows Phone blog. It's all being handled very strangely. I remember they even said at one point that this update would bypass the carriers.
  • Yes, at least, I received an email informing me about it though I already forced my phone to update via Zune.
  • I'm an HTC Trophy owner, I feel your pain. I'm lurking over here because my step daughter has a 710.
    Got a Tweet from T-Mobile after berating them a little bit...maybe all is not lost. This is the tweet that I received:
    "We're always working on updates :) keep an eye out at  for when it is! ^LG "
  • "though we suppose with the carrier cost of testing the update and the perceived benefit, they decided against it"
    This is the biggest sham ever perpetrated on consumers.  There isn't JACK SHIT that they need to "test" except "does this cause us to lose money on shit we shouldn't be charging for" and for that I could care less.
    Microsoft should never stand up on stage and make promises that all phones will get it if indeed they won't. 
    Oh and Microsoft, where is that enthusiast early upgrade program you ALSO promised?
  • Lets make sure I got this right 710 is not getting it right And if not is there another way I can do it
  • Have you read any of these comments are looked at the last 2 days of articles god damn
  • It was a fucking question mind ur own fucking busy ass hole
  • Its a stupid fucking question in a fucking public forum so its my business the fucking question had been discussed at length on here stop reading articles then going to the fucking end of the comments and asking a question that's why there are hundreds of post to read through on every fucking article people just going and asking the same questions over and over just read first
  • Unless you use sevenieighter or the manual .cab method, then you're not getting the Nokia Lumia 710 WP7.8 update.
  • This is why carriers should have no say in phone updates, smdh
  • One question why tmobile?
  • Why not, when my monthly bill for 3 people is over $50 less per month than the equivalent service from AT&T and Verizon. If Microsoft/Nokia sold unlocked/unbranded frequency-compatible phones, I could buy a new phone every year and my yearly total would still be less than being on AT&T/Verizon.
  • ...with the added fact that T-Mobile is the only carrier offering unlimited data plans for cheap besides Sprint (Unless my facts are outdated of course). The magenta clad carrier is also in progress in offering LTE coverage to customers.
  • Microsoft: All* WP7 devices will get 7.8
    HTC: Not the HD7
    LG: Not the Optimus Quantum
    TMo: Not the 710 That asterisk is getting bigger and bigger...
  • I though everyone was panicking prematurely until I saw the friendly disclaimer on Microsoft's Windows Phone 7 update history page under Update 7.10.8858.136
    "This update is not available in all markets or for all phone
