Well i'm trying to update my Nexus 7 2012 to Android 5.0.2, after receiving the OTA update but keep getting an error.
I rooted my Nexus 7, and been thinking that's the problem, since it restarts to install the OTA update but goes to Recovery mode, and when i try to manually install the file get the following error :

Any tips or solution for the problem?
Thanks in advance

Thought you would say that! .
You can always:
- download the image for your device from the google nexus website I gave you
- unzip the tgz file
- Find the resulting tar file and unzip it
- you will now have a folder
- inside the folder will be a bootloader-grouper-4.23.img file, image-nakasi-lrx22g.zip file, flash-all.bat file and two .sh files
- unzip the zip file to the same directory as the bootloader-grouper-4.23.img file
- reboot your nexus into bootloader mode
- plug the nexus into your PC
- open a command prompt in the same directory as the image, sh and bat files (on windows 7 hold the shift key and right click on an empty space within the folder and choose open command window here)
- in the command window type fastboot devices, make sure device is recognized
- if not, set up your pc for adb and fastboot, if so, continue
- type in the command prompt:
fastboot erase boot <hit enter>
fastboot erase cache <hit enter>
fastboot erase recovery <hit enter>
fastboot erase system <hit enter>
fastboot flash bootloader bootloader-grouper-4.23.img <hit enter>
fastboot reboot-bootloader <hit enter>
fastboot flash boot boot.img <hit enter>
fastboot flash recovery recovery.img <hit enter>
fastboot flash system system.img <hit enter>
fastboot reboot <hit enter>
This will preserve your app and data settings.
If you had custom recovery installed just reboot into fastboot and flash the recovery of your choice. example: fastboot flash recovery ,recovery image name>
If you want to reroot, download a superuser zip file to your device, reboot back into your custom recovery and then install the SuperUser zip of your choice (i.e. chainfire's SuperSu)
Hopefully this is straightforward and self explanatory
Thanks for the tip and explanation Skeetch79, will try to do like you wrote.

This method works great! I was in the same boat. I analyzed the updater script and then analyzed the ro.build.fingerprint from my system, and it doesn't contain the weird one that it errors out on. I debated just removing the build prop check and repackaging it as an update, but decided against it.
@lmcmil - per chance, did you flash a different kernel and/or switch to F2FS before this happened? If so, that might correlate to mine, since I did do that....
Either way, I'm gonna run stock again for a while and see how it feels.
EDIT:
I think these lines:
Code:
mount("ext4", "EMMC", "/dev/block/platform/sdhci-tegra.3/by-name/APP", "/system", "max_batch_time=0,commit=1,data=ordered,barrier=1,errors=panic,nodelalloc");
getprop("ro.build.fingerprint") == "google/nakasi/grouper:5.0/LRX21P/1570855:user/release-keys" ||
getprop("ro.build.fingerprint") == "google/nakasi/grouper:5.0.2/LRX22G/1649326:user/release-keys" ||
abort("Package expects build fingerprint of google/nakasi/grouper:5.0/LRX21P/1570855:user/release-keys or google/nakasi/grouper:5.0.2/LRX22G/1649326:user/release-keys; this device has " + getprop("ro.build.fingerprint") + ".");
are what causes it to explode. First, it tries to mount ext4 instead of F2FS, which makes sense, but would cause the system partition to be unreadable if you converted it to F2FS. That COULD explain the odd "deestroy" build prop it thinks it got when it pulled ro.build.fingerprint, since when my system was fully booted mine matched the stock LRX21P using getprop from adb.
toastido i tryied to load the OTA using the Nexus Root Toolkit and the error i got was regarding missing calculator, wich i removed after installing "Calculator ++" app
Still haven't had time to try this method, i'm working this weekend so only next week i can give it a try and post the result.

Good Man !!!
Thanks Very Much for that one,
I got stuck on the boot after performing the advised but a quick Cache Wipe sorted that out.
Once again Much Obliged !!!
Yeah forgot to mention the above. if you are stuck in a boot loop: shut down. reboot to recovery. wipe cache and dalvic. Reboot. Profit.

Does this also work if I want to go back to Kitkat? I am asking, because I've tried the following:
Code:
@echo off
echo. listing devices:
fastboot devices
echo. To continue press Enter
pause
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
REM adopt the following line according to the bootloader image filename
fastboot flash bootloader bootloader-flo-flo-04.02.img
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And no matter, if I do a wipe cache afterwards or not, I end up in a boot-loop.
Do you know a way to keep apps and settings while going back to Kitkat?

TWRP is incompatible with 5.x OTA: it uses its own moronic default.prop instead of importing the device build.prop (or something like that) . It needs to be fixed.
You have to bother flashing the full image (minus the wiping eventually) and reinstall root & TWRP with every update, just like the rest of us
Got an Failed error at fastboot flash bootloader bootloader-grouper-4.23.img <hit enter>.
So now i don't have a valid bootloader and also can't enter recovery because it was erased at fastboot erase recovery <hit enter> step
And also typing fastboot devices my Nexus 7 isn't detected, what can i do now?

Well decided to use the Nexus Root Kit and flash the full image LRX22G, doing it now.
Will post how it went.

I had the 2012 Nexus 7 WiFi before I picked up the 2013 model. I had the same issue with that bootloader. Seems to be a common issue. Here are articles discussing the issue and fixes.

https://code.google.com/p/android/issues/detail?id=62198&
http://forum.xda-developers.com/showthread.php?t=2573015
I remember flashing a modified bootloader to resolve the issue, since as you can see the bootloader packaged with the images is borked.
EDIT: try flashing the appropriate bootloader from this thread: http://forum.xda-developers.com/showthread.php?t=2417097

Thanks for the great tutorial! Used it yesterday on my rooted Nexus 7 to upgrade to 5.0.2, worked like a breeze! :good:
Afterwards I used WugFresh's Nexus Root Toolkit to regain root.

I followed this tutorial yesterday and everything went great I now have 5.0.2 working on my Nexus 7 2013, with no problems I can detect at the moment. Thank you, because I was just frustrated I saw the OTA notification without being able to do anything.
Cheers.
I try it too 5.0.2 ota update and nothing still on 4.4.4 I guess on Lollypops for me
I need the flashable stock rom for 2.21.40.30. Can someone give me the link
All the ROM downloads can be found here: https://www.asus.com/support/Download/39/1/0/2/96nqlxHp1VKV4Rdz/32/
Firmware you want:
WW SKU (recommended)
TW SKU
CN SKU
CHT SKU
It's always recommended to after downloading the ZIP (on any stock version), reboot to droidboot then:
Guide for Zenfone 5 (T00J - A501CG, T00F - A500CG) only!
From inside the ZIP, extract the files fastboot.img (note that sometimes fastboot.img comes as droidboot.img), recovery.img and ifwi.zip
From ifwi.zip extract the files dnx_fwr_ctp_a500cg.bin and ifwi_ctp_a500cg.bin
Now, flash the files in the following order (via droidboot):
NOTE: The first line below, the fastboot.img I mention is of 2.21.40.30, use this fastboot image to flash a dnx and a ifwi. Other ones may not work! As you using this version, I'm not sending you it separately
Code:
fastboot flash fastboot fastboot.img
fastboot reboot-bootloader
fastboot flash dnx dnx_fwr_ctp_a500cg.bin
fastboot flash ifwi ifwi_ctp_a500cg.bin
fastboot flash fastboot fastboot.img
fastboot flash recovery recovery.img
fastboot reboot-bootloader
It's also ULTRA recommended that you erase your data and cache:
Code:
fastboot erase data
fastboot erase userdata
fastboot erase cache
Now flash the ROM via adb sideload on recovery
I recommend doing this before flashing any stock ROM when coming from a custom ROM.
Thanks
No I meant flashable from TWRP recovery. I learned that method by heart
In cmd typing "adb devices" shows empty list.
all drivers are already installed.
my phone is not shown in 'adb usb" also.
help me
