Flash the factory image with fastboot. Backup first.

If you followed the instructions at https://developers.google.com/android/nexus/images what was the error or problem?
I guess you'll never get an OTA because LRX21K was never a general release. The other alternative is the "Nexus Root Toolkit" that has a stock restore/upgrade http://www.wugfresh.com/ . You could have issues with LRX21K not being a supported rom so I think at "NRT" start up you should manually set the rom as LRX22C . You can let the package download the new rom or if you have it downloaded you can point the package to the rom when you restore/upgrade.

Jelly Bean 4.2.1 OTA

So I just received a 1MB OTA which took my version up to 4.2.1. At the very least, it fixes the missing December issue in the People app. Given the size, I doubt there's too much more in there.
Any performance improvement? Can you run an AnTuTu 3 test?
Keep root? Any problem with unlocked bootloader (but stock cmw and rom, only bootloader unlocked)?

It's not visibly faster, although I didn't have any performance issues before either. Disabling Currents pretty much fixed it for me. I can't find antutu 3 on the Play Store, is it just called "antutu"?

Sorry, I haven't rooted mine so I don't know.
Does anybody know how to get this update on a Rooted device with custom recovery?

Sideload possibly; but in any case, someone needs to provide an update URL.
Does the update keep root?

Just download AnTuTu, and you'll get the latest version, I think.

Were you experiencing any freezing or reboots prior to the update? I wonder if this addresses that issue. If not, this thing is going back.
Sent from my Nexus 10 using Tapatalk HD
I dunno, maybe I'll just unroot, relock and grab the OTA...then try to re-root and unlock again.
Any chance you can still catch the filename of the downloaded file?
I have not yet received the ota update. I'm currently using unrooted 4.2nexus10. Buy I'm currently in the Philippines...
Can any expert tell me if i can still get the update or should i just manually download... If so how to manually apply update... Hope anyone out there could help

You should get the update eventually automatically. Otherwise (once someone provides an update URL) you can just take the package, and adb sideload it from Recovery (boot device to recovery; do update from adb or whatever it's called; on the PC, do adb sideload UPDATE-NAME.zip)

adb is for Android Debug Bridge
All you have to know is here : http://developer.android.com/tools/help/adb.html

Then please tell us the exact filename of that zip file. It should look like this:
Code:
123abc456def.signed-manta-JOP40D-from-JOP40C.123abc45.zip
The numbers in front and at the end are especially important.
You can maybe clear data from the Google Services Framework and then try polling for the update.
I just want to know if I am unlocked and rooted will I keep those? I am still on stock recovery and rom, but I did add AOSP browser to system/apps manually so that may need to be removed I believe.

I don't think a 1mb OTA fixes performance issues. More like adding December back into the contacts calander

OTA failed due to beats audio

Hello everyone.
This is my first post and unfortunately, I need help!!
My wife has a droid razr that got the early xmas jellybean update. Phone has been rooted as well. My wife decided to download all sorts of root apps and installed the beats audio app without backing her stuff up. Well now the official jellybean OTA is being pushed to her phone, and she cannot update. I have tried via OTA, and sideloading the file that I pulled.
This is the error she gets:
assert failed: apply_patch_check("/system/lib/libwebrtc_audio_preprocessing.so", install aborted
Is there a way and can download the original files that were supposed to be there before beats changed it??
Thanks for your help!
You can flash back with rsd lite the complete firmware, that should restore it..

I'm not gonna sit here and pretend like I know how to do that, sooo....whaaa? lol
Where do I need to download the firmware? Do I have to download one for the xmas jelly bean release?
Also, I tried downloading just the audio_.......... files off 4shared and replaced the one in my file system. That did not seem to do the trick. Do I have to have a specific copy of it??

Look at the stickies in your phone thread and there should be a thread about reverting to stock. Just follow the guide there and you should be fine.
If it doesn't revert to the latest version then you will receive an ota notification. If you want to make sure you are on the latest firmware just go to setting-software update.

[ROM] Lenovo a760 clean android rom wanted

I'm looking for a clean android multilanguage system without china applications and letters for lenovo a760. Have anyone tested customs ROMs for this phone? Android system which is installed on the phone is not userfriendly and I have a problem with many applications and Aero.
http://forum.xda-developers.com/showthread.php?t=2434453 Try to root with this method. Remove ONLY HAVIEST CHINESE SYSTEM APPS, we still don't have a rom to flash if we delete important stuff by accident. . Use more locale 2 until maybe a ROM is developped. As an alternative market use www.1mobile.com
When I get my phone I will try to build a rom for it. I kind of know how to do it...never built one before though Any help would be appreciated
Any update on this? I've been searching for days to find any sort of modification for the a760 but to no avail.
I like the current stock rom, however some apps are in Chinese and i would like for these to be translated so i can use them.
I'd also like the latest firmware, i downloaded it several times via the OTA updater but it just sticks on 100% and if I try to access the file through the file explorer it says it's corrupt.
Thanks.
Sent from my Lenovo A760 using xda app-developers app
Once I receive it i'll start experimenting I should get it in about 1 week I guess...
I've managed to download the latest firmware for my a760 I downloaded it from my pc as when I did it on my phone it hung at 100 %
However I don't know how to install it. It's currently in the googleota folder (where the phones OTA updater downloads it too) but nothing happens in system update menu in settings.
I've tried to flash from stock recovery using sdupdate but it says no file found.
Do I need to rename the zip? Or move it elsewhere? I've had it on the root of the sd too.
I'll be more than happy to share the file with you so you can tinker with it, just let me know if you want it. However I'm guessing the majority of it will be Chinese like our current rom.
Thanks
Sent from my Lenovo A760 using xda app-developers app
Right considering this is the only thread on xda in regards to the a760 I will list my problem here.
I download the ota update, I couldn't install it via the phone so I flashed it through Cwm recovery, it worked and put me on the latest version, however I think I may have pressed a few wrong buttons in Cwm as it was in Chinese and i installed it blind using previous knowledge of Cwm from other devices,
Anyway the phone is operational but the new version won't allow me to use anything Google, not sure if this is fault of my own or the Chinese rom makers want us to only use their app stores.
Each time I open play store it just closes instantly, not FC it just won't load. Also when I open some apps they do FC, such as titanium backup, play services, superuser (English one) ect.
My final issue is that I cannot mount system as RW, i am rooted but still can't mount RW.
I don't know if my problem lies with the recovery image, the one i flashed before all this was a Chinese Cwm image for A706 (many reports of it working for the 706 and it did for me)
My logic is that if I can flash the stock recovery image all will be back to normal.... After the update Cwm has gone, I have android stock recovery 3e now. Any opinions on this?
Also if anyone has or knows where to get the older firmware that'd be great as I preferred it over this new one. I have asked the seller to source it for me but no reply as yet.
Thanks, and sorry for the massively long post!

i was also trying to flash the recovery but no luck.How did you manage ? I was trying to push it with adb...We have exaclty the same issues..Have you try to flash the gapps threw the recovery ?
This is wthat am trying to do..Flash the recovery in order to flash the gapps
I flashed the recovery using an automated bat file, I think basically it was just fastboot flash recovery recovery.img or adb flash recovery
I do not have Cwm any more, since I updated I lost it and ended up with stock android recovery.
I've had a 15 hour shift at work and have only just got home so haven't been able to get on the PC and try n fix it. But I will have a quick go now before I go to bed.
Can you link me to or upload the gapps? Are they the correct ones for a760? This may fix my Google issues

That's the reason I found this topic. I tried to update via OTA and it was installed other system completely chinese and without google play, for this reason, i'm afraid to try to update again...
This update: A760_1_S_2_001_0133_130828 (418MB), but I don't know if it'll install the chinese firmware without google play or not...
I also installed it and it gave me too many problems. It's more Chinese than the current rom and would not support anything Google. Gmail / play store / play services all blocked.
My advice will be to stick with the firmware u have at the moment and wait for someone to modify it. Or have a try yourself. The link a few posts back will restore ur device if anything goes wrong

I had one also. Didnt care about losing root since it is easy to re-do. I took the OTA however it failed to install with "error". It put me back to my previous build and that was it. Update doesnt show as being available anymore. Oh well...
In order for the ota to work you need to be on the stock recovery, kernel and system files. Make sure you're on those and the ota works fine

Sent from my Nexus 9 using XDA Free mobile app
I've read of WiFi issues, lags and general hiccups with the new OTA. To be fair, most of the issues I read about were with older Nexus device (5, 7 and 10). I'll go ahead and upgrade with my fingers crossed...
Reverting to stock
I also rooted but have gained zero benefit this early on. Are the factory images out and is that the best way to be able to take the update?
Thanks for any help!

I had the same error.
Using the stock recovery diddent fix it for me.
I just downloaded the latest factory image from google.
And manualy flashed it to my nexus 9.

Look up the vid were he updates to the q update.
Just replace the files he uses with the latest factory image files from google.
What's interesting is that even with the error my system says it is on R now. I then rooted again and my tablet seems to be running fine. I debated just wiping it out and flashing the stock image, I'll do that if I ruin into any strange problems...

New Firmware G900TUVS1FOL1

I got an OTA notification this morning to install G900TUVS1FOL1. Went ahead an applied the OTA update and everything seems to be running much better than before. A lot of the lag that I was seeing before is now gone. No word on battery life as I only had the update installed for about 12 hours. Figured I would let people know that there is a new update available. Haven't seen much information posted about it.
I am unrooted BTW, so I can't really answer any questions about that.

hello have a galaxy s5 T-Mobile sm-g900t like that if it were possible postasse how he rootear your most detailed device if the model is the same as mine, have android 5.1.1 g900TUVS1FOL1 from already thank excuse my English'm from Brazil.
Hey gang!
I have the metropcs variant (G900t1) of the Galaxy s5. I downloaded the .tar file. I wiped my phone first (twice for good measure) and rebooted to download mode via TWRP. I *did* uncheck the auto reboot box because I hears odin acts funny around OTA's. After the reboot was done, my phone got stuck on he splash screen for a while. I popped out my battery.
for the record, not a noob but leery about regaining root using cf autoroot.
XDA, check me on this. I want to do this right. =)
I updated via Kies earlier this afternoon. So far it's very snappy.
