Windows 10 for phones preview pulled for Lumia 520, 525 and 526

If you own a Lumia 520, 525 or 526 smartphone and have yet to download the new 10051 build of the Windows 10 for phones technical preview, you will find that it is no longer available. Microsoft has pulled it from circulation for those devices due to problems with rolling back to Windows Phone 8.1.

A number of users who own those three Lumia models have reported those smartphones were bricked when they rolled back to Windows Phone 8.1. They were using the Windows Phone Recovery Tool after installing the Windows 10 for phones preview. A Microsoft rep has confirmed those reports on the company's support forums and added:

"We are pausing build availability for these devices temporarily while we investigate the issue and work with customers who have reported problems."

Microsoft released the 10051 build of the Windows 10 for phones preview last week, along with a list of known issues with the build.

  • Thats a good save!
  • Mine too +520
  • You could try Nokia software recovery tool. Worked for me when Microsoft failed
  • @Kirsutin was ur phone also dead completely or it hanged at the reset screen (gears spinning ) ?  
  • but it is saying "package is not available for this product"  
  • Well.. I rolled back. It got stuck after downloading and installing 8.1, i hard reset it and working more than fine now. Its smoother than how it used to be
  • Hey buddy my phone(lumia 520 )  has gone dead too, what do i do now? no display nothing !! 
    how do i reset ??
  • Hey bro, here is the link to reset...
    http://www.hard-reset.com/nokia-lumia-520-hard-reset.html
  • Even this is not helping bro !! My phone seems to be dead to all things!
    except it gives the connection sound when i connect to PC :P
  • Dude wait for it to lose all it battery energy!
  • Then charge it even if no sign of chargement is taking place! Then after 1 hour , make the hard reset ! As the link stated!
  • T​hat's not going to work, when a Lumia 520 gets bricked by this, hard reset will not work either. Neither will your phone charge.
  • Hey don't worry that happened same to my 520 , I did this: First download and install Lumia recovery tool for your lap or desktop and connect your phone to PC via USB after this launch recovery tool this will shows somethin and in that select my phone not detected then that tool automatically starts detecting your phone model and starts downloading the OS and then follow the instructions as tool suggests don't remove phone from PC until it get completed it may take half an hour and more depends on data speed and it's about 1.5 gb. And its worth to wait.
  • NO dude after getting bricked, recovery tool is not even recognising the phone !!
    though if someone gets out by this way tell me too :P
  • same here 720 bricked and no recovery tool working.. checking for a good repair shop having JTAG to recover my phone
  • Exactly same issue with my 520.... Just gives sound when connected to USB and nothing else.
  • See the my comment below on @studio384 and follow the procedure
  • Lumia 620 from wp8.1 to a laggy w10 and no recovery possible with windows phone and lumai recovery, nokia care suite or lumia suite, nothing works. Had red screen od death and then went black. Dead phone doesnt response to any buttons only sing of life is sound when I connect and disconnect it
  • Exactly the same problem but no one is getting it, plz understand that not even "power"+ "vol - "  is not working!! and someone plzz come up with adequate solutions!
  • My Lumia 620 downgraded to wp8.1 from win10 perfectly through windows phone recovery tool.
  • which one did you use @Jena? thanx
  • Happened to me too a month ago. I gave my phone to Nokia care, they said it would cost me INR. 3500 ($56), but after 15 days, they told me that they were unable to fix the phone, its completely dead now.
  • They replaced my phone :)
  • Thx for the motivation .... :-)
  • charge ur phone with charger for batteries...then put the battery in the phone and connect it to PC...then try again 
  • someone said nokia care replaced the motherboard for INR and got the phone back working all in 15 minutes.....sounds unbelievable to happen in India... but I'm gonna go to Nokia Care to replace motherboard.
  • If u are going today plz do update what do they say!!
  • my 720 is dead and noika care (in Delhi India)is asking for 15k (~250$) to replace motherboard  :(  sad service..  
  • really?! that's unacceptable. that phone is not even worth 10k in the present market condition..
  • See the my comment below on @studio384 and follow the procedure you'll get your phone back.
  • I had a similar problem - check my blog post to see how I fixed my Lumia 520. https://zudomc.wordpress.com/2015/04/17/dont-install-the-wp-10-tech-prev...
  • your things look satisfying but my fone is dead, its not showing those spinning cogs, i can't even check how much it is charged
  • Man, it fixed my dead phone! I was going to throw it but you saved it man! Thanks a lot!
  • my lumia 520 suffered from same epidemic disease. I went to Nokia care point and those people replaced the motherboard of my lumia for 3000 INR (50 $). now, its healthy again and working like a new set.
    now OS is windows phone 8.1 obviously. my phone was OUT OF WARRANTY
  • Thank god I didn't installed it.....
  • hey bro help me plz i got failer during roll back lumia 525 and now become stoped working and it showing only black nokia screen so plz help me out to solve this problem...
  • I was bout to install it
  • I had it on my 1520. it was a bad idea. Drained 2GBs of data in 4 days for some reason. AT&T charged me $10 for overages lol. Plus it was just too glitchy to have on my main phone. I should have further heeded the warnings. So today I was going to install it on my 520 instead (it's my jogging mp3 player basically; figured I could give it a second function). Good thing it was pulled. I wouldn't want it bricked.
  • My 620 almost had this problem too, Lumia & Windows Phone Recovery Tools always fail to flash my phone, and it stuck at Nokia logo at start up. Luckily old software, NSU can solve this problem. I think they should pulled W10 for 620 too.
  • Still won't install on my 620 :(
  • Patience is a virtue! I recommend to all to wait for the official release of w10.
  • Nope. Its working well on L620. Apps are slow , crashes sometimes. but not too bad. I am using it.
  • When I tried to roll back on my 620 with Windows recovery tool it messed up. However I was able to recover with Lumia software recovery tool.
    In short what my thoughts, Microsoft has completely failed after acquisition of Nokia devices division as for as quality Is concerned.
  • lmao
  • This! Highly recommend using NSU if else fails
  • My 920 went straight from cyan to win10.
  • I successfully rollback to windows phone 8.1 from windows 10 yesterday only. Once upon a time I thought that my phone was bricked but hoosh after 3-4 attempts I am able to rollback.
    Those whose phone got dead while rollback don't worry try 4-5 more times it will work.
  • Mine is so slow it is unusable. I was going to use the recovery tool maybe I should wait Posted via the Windows Central App for Android on my Oneplus One
  • No prob with 830, no?
  • Nope.
  • Works nice for me. Just the keyboard is too tiny hehe :)
  • That what she said
  • nope. I rolled back yesterday with no problems.
  • Ok,thanks
  • iTroll. Lol, nice nick ^_^
  • Lol yeah.
  • (^_^)
  • A recovery tool turns out to be the killer, never would've guessed. Next your going to tell me it was with a candlestick in the foyer.
  • Would have*
  • Would've
  • Should've
  • Could've
  • I know the article is referencing th 530 series, but the recovery tool did a perfect job restoring my 1520. They should also pull it for the 1520 as well due to the fact that is made the mercedes benz of WP run like a fiat!
  • I'm loving it on my 1520. Wouldn't go back now. Plus it's not nearly as buggy and laggy as I'd thought it would be.
  • More like a "Yugo". 
  • A Ford Pinto, or Chevrolet Chevette
  • And I think it's the Windows Phone Recovery Tool. I tried to bring it back with Lumia Software Updater, but it won't recognize the model. Phone's showing up like "Nokia Emergency Device".
  • That's some serious problem...good they let people know before more ones got bricked
  • Serious problem and i am sure that everyone was annoyed by the popups and warning before installing and signing up for insider programs. If you use the 520 as your main phone why would you put Win10 on .. if you dont. than fuck it.. they are cheap phones anyways
  • Reading comprehension eludes many for the TECHNICAL PREVIEW it seems. There will be problems they said, it could brick your phone they said and yet many don't get that expect the builds to be flawless.
  • Not sure why anyone would be rolling back if they listened to numerous warnings of who this technical preview was intended for. Purchase used hardware for testing and this won't be an issue.
  • If I use a 520 as my back-up/developer phone and it gets bricked, I still have to replace it.  Just beacuse they are cheap phones doesn't mean it is no big deal to brick it.  Most people don't have money to buy new phones all the time, $50 is still a lot of money for me.
  • Ebay 2 for $10 with free shipping.. even for spare parts like screens & batteries, it made it all worth while.
  • There was a 526?
  • Chinese variant of 525
  • L620 :)
  • +620
  • My 620 had problem too when flashing with Lumia & WP Recovery Tool, always fail and make it stuck at nokia logo at start up. Luckily NSU can save it.
  • So glad they did this before it got out of control. I hope fellow 520 users are happy now; if they hadn't released it at all, the whining here would've been through the roof. I hope people take this issue more seriously, and lower their expectations, because it's extremely early and unstable software, on almost 3-year-old hardware. That's never a good combination.
  • I installed it on my 520 several times. Never any problems rolling it back, but the home and back buttons were not functioning whilst W10 was installed.
  • I installed it on.my 520. Everything worked as it should, but W10 is a little sparse at the moment to say the least.
  • hi,  I am facing same problem. I am using lumia 620. have you found solution yet?
  • I have W10 TP on Lumia 521 that's not even on list of devices to get that!
  • I have a 521 as well, for all intents and purposes Microsoft treats the 521 like the 520. If the 520 is listed it means the 521 is suported as well.
  • Is there Lumia 526 ???
  • Ativ S can download the preview!!
  • wait can it? just like any lumia?
  • Yep
  • Be cautious though. Ativ, although a great phone, has had problems even with Dev Preview builds. You might want to tread safe.
  • Well the Nokia tool works just fine. I have tried
  • The tech preview is a good reminder of how insanely complex it is to build an operating system. 
  • Yup, pity 95% of the general populous do not understand that.
  • They do understand. Complexity or bugs are not the real complaint. Its the overall wp direction. 95% of the WP general populace are smarter then you think. I'm sure the 5% probably of the populace don't understand that.
  • They somehow manage to do it with big windows which needs to support millions of hardware configurations compared to just a few on phone side.
  • @techfreak1: I think your comment are correct less. People who decided to install WP 10 TP already knew what bugs they will experience in. But on my experience the bugs are in the crucial phone function like the notification that won't automatically turn back up, I have to press the lock button to make it return to homepage, it's ridiculously annoying. My Lumia is 535. I don't know if it happens to another Lumia model.
  • Off topic: Bing not giving cricket fixtures or predictions or anything...
    Anyone else?
  • Yes, same here. It stopped me giving predictions. I thought I was alone.
  • We WP fans are alone...
  • I waiting. Lumia 920
  • The 920 already has it. Its install on my 920
  • I've stopped the upgrade process after GDR2 on my 920.
  • Did anyone have installed Windows 10 tp on high devices like 1520 or 1020? Is there any problem appear?
  • Check the forums.
  • I put it on an old 920. Quite rough around the edges, but nothing stood out as broken. But, no way would I install on my daily driver. Not even close to ready for prime time yet.
  • Office is broken.
  • nothing much on my 1020. just some bugs on some apps. :) cellular data toggle works too .
     
  • Yeah, L1020. Lots of bugs, crashes and resets - but that's to be expected. The feedback tool has been my companion! The only way wp10 is going to get any better is through lots of feedback, so I'm keeping it installed.
    Luckily I just picked up my free EE power at today, so the ridiculous amount of battery I'm going through each day is less of a problem!
  • i did as soon came out on my Lumia 1020 and hardly regret and that's why 2 days after i rolled back to 8.1.Reasons why on day one data conection was switching on and off by it's self and i don't have any data plans with my operator so i spent like $10 for nothing.Day two the the phone didn't recognized my sim card it says no sim and right after the screen goes down i can't turn it on i have to use soft reset buttons to bring back the screen in live.So i wouldn't recommend to install TP better wait till the official release.Luckily for i used Windows phone recovery tool to roll back to 8.1 and now everything is fine
  • Thanks a lot friend for the information. Well actually imma bout to install wp10 tp on my 1020, but in deep heart keep thinking if any problems or bugs would appear. And yeah! The light shows me the path. Ya, better wait for the official one released soon ;)
  • Installed it on my 1020. It worked fine initially, but after a reboot it stopped recognizing my SIM. Bought a new SIM, wouldn't recognise it either. After resetting the phone from the about screen it started recognizing the SIM again. But it took about 2 hours to complete the reset, the settings didn't fully restore so I had to spend another 4 hours changing settings back to normal. The settings app constantly crashing didn't help. After this I didn't have any major issues in the last 2 days. But I wouldn't recommend to install it if you don't have time to invest in fighting/fixing the broken stuff.  
  • When will it release on L535
  • Already available...
  • I rolled back my 520, had to run the recovery tool twice to get it to work though.
  • I installed WP10 on my 520 and now want to roll back. I accept the challenge.
  • Hm, but i successfully rolled back my lumia 525 from win 10 to 8.1 with help of lumia recovery tool. It is some different tool, or i just lucky?)))
  • How did you find the Win 10 preview? I really want to put it on my daily driver 525. Don't have the cash for a new WP xD
  • Phones had a problem rolling back via the windows phone recovery tool which was coincidentally stated as a safe tool to rollback by ms. You just got lucky :D
  • Please I need your help? Do you still have the package on your computer? None of the tools can find the package for my lumia 525. Could you please upload it on internet and give me a link to download it? If you could help a poor guy like me. I beg you ^^
  • It did work for a few people
  • I think it is pulled back for Lumia 620 as well. I first installed Windows 10 and then rolled back because of data connection issue. After rolling back when I tried to reinstall Windows 10, I did not get the update.  I am anyway waiting for the next build with some issue fixes, especially the one related to data connection.   Thanks,
  • Wasnt a good experience on L620?
  • Yeah.. Worst experience actually
  • No. I use internet over WiFi only and not on mobile data. So even when the data connection was OFF, I was being charged for data usage. Secondly, everything was crashing a lot, may because of low RAM and my phone was loaded too. I will wait for the next build.
  • May b coz of less RAM & earlier build...
  • 525 has one GB ram
  • Part of those TP caveats was increased data usage. Has to be a leak somewhere.
  • Yes seems to be. I will try the next build. Will stay on 8.1 for now.
  • I rolled my Lumia 925 back. It is back on cyan but can no longer receive any updates at all. It is something to do with the time on the phone not being same as server and I have to update the time manually. It won't sync automatically. Dunno what to do.
  • Just go to care. They may have the latest updates
  • Why not force updates through Dev Preview?
  • Should I update my Lumia 520 to wp 10 is?
  • http://windowscentral.com/commenting-guidelines
  • U do they release if they know the issues... Pathetic
  • No issue for me in rolling back to 8.1 it was smooth no hiccups just hoping the new build solve the data connection bug
  • I have an 1520. After using it for a week, I decided to go back to 8.1. The phone restarts itself after clicking on a picture in a text message. The touch becomes unresponsive 4 times in a single day. I had to soft reset it to make a phone call. Not able to answer phone call is frustrating. Even for a technical preview, there has to be some basic standard. It is very badly managed.
  • Try doing a reset of the phone
  • Good that they did it. I hope they fix it and release it soon. I am glad that I didn't installed it in my phone
  • Too late for my 520. It doesn't even turn on after using WPRT. Yet, it's somehow stuck in flash mode. Just got the 635 to replace it.
  • My L520 is already dead! Tried everything except jtag :( 
  • I also did the rollback to 8.1 and I too felt that my phone has been bricked as the spinning gears went on and on for 12 hrs but then I removed the sd card after removing the battery directly and voila !! the spinning gears went on for some minutes and it rolled back successfully  
  • I've 525 and I just opened insider app and it said build is available for your phone select the ring. Everything worked fine but I stopped installation I.e. Did not let phone reboot
  • I am one of them whose 520 is no more !! :(
  • Me too bro
  • Given to local for repairing... :(:(
  • Try Nokia Care Suite , worked for me.
  • Mail me the complete procedure at sujitintel@live.com .. :(
  • I followed this thread to download and configure Nokia Care Suite: http://forum.xda-developers.com/showthread.php?t=2515453  
  • I gave them too a month ago when i had similar problem.They were charging me Rs.3500 but returned it after 15 days saying, it can't be fix now.. its completly dead.
  • I couldn't get it work on my 1520...
  • I has roll back
  • Thanks all who are participating to make this OS more refined.
    I cant put it on my primary/secondary/dailydriver/only one 620.This is too scary.
  • Thankfully I was able to roll back to 8.1 without bricking my 520, though it did fail a number of times initially.
  • I have a bricked L520 because of rolling back from win 10 to win phone 8.1. It is my primary one. Time being m using my brother's L730. Hope MS fixes the issue and gets my phone back. MS please do something.
  • Same here bro... Got a L730 after 520 bricked !!!
  • It also bricked my 635!...No love for me.  Having to stop by the ATT Service Center today to see if they can reimage my phone.  
  • I am definitely not going back!
  • I used Lumia recovery tool to jump back to 8.0. It was easy.
  • 535 please
  • So you want a broken 535?
  • My L925 bricked when tried to rollback to 8.1. It was my primary phone so I had to get a new L635 to use until an official W10 phone is released.
  • Please tell what to do if my phone has been bricked in this way? No display no response not even charging notification !! :(
  • quick question but what happened to office, becuase it is nowhere to be found on my 928 WP 10 preview ??
  • It was pulled of from the current TP..
  •  o ok is there any alternitives to get it back? or use a thrid party app ?
  • Only waiting. They said it will be available for download
  • They should have used Lumia Recovery Tool...
  • I installed it then did a hard reset and rolled back
  • I had trouble rolling back on my 1020. I think my mistake was loading the backup that was taken while running W10. It screwed up my mail. I no icon in all apps for mail, just a setup mail on home. When I tried to add my outlook.com account, it said it already existed, but there was no way to open it. I eneded up having to do a reset and load an older backup, but then I realized that backup was from the latest 8.1 and the recovery tool restored base 8.1, so I lost my home screen configuration and all that.
  • My start button is super unresponsive on my Lumia 520 w/ Windows 10. Anyone got a similar issue?
  • Yep, known issue.
  • All keys were bit unresponsive on mine..
  • So if I have the preview installed on a 520, what do I do?
  • You do realise that this article is not about the 1520?
  • My mistake, typo!!
  • Haha, and I just sent in my phone for repairs, we'll see what they say about warranty stuff for the L520. Oh well - a minor setback.
  • Use lumia software recovery tool to fall back to windows phone 8.1 from windows 10. I have used it on my lumia 520 for upto 3-4 times and my phn is still working perfectly doesn't know what will happen if you use windows phone recovery tool......
  • After update 2 L625 downloading wp10 hang with 53% please fix it
  • Please use the forums.
  • Bricked my 520.
    MS would be giving any solution or need to go to NCC?
  • I was able to r
