[Q] sideload upgrade to 4.2 - Nexus 7 Q&A, Help & Troubleshooting

So I am trying to adb sideload 4.2 and its failing at the update, specifically "verifying current system....assert failed: apply_patch_check("/system/app/MusicFX.apk") and a bunch of numbers then Installation aborted. Im running stock rom 4.1.2 and the update originally failed after the OTA so I decided to try manually and same thing. Anyone have any ideas?

Download the full 4.2 factory image from Google's Nexus factory images page and fasboot flash that

Thanks, yeah I can do that but it would wipe my nexus I was hoping to just update

I am updated, running the 4.2 update. I shouldn't have any problems flashing ROMS correct?

Just flash the system image only, via "fastboot flash system system.img" (extract the ZIP in the download), no wipe then.

4.2 update assert failed with a fresh install.

Hey, I've already flashed the factory image for 4.1.2 but when I try to apply the OTA patch for 4.2 I get the assert failed: apple_patch_check error.
I have tried to reflash the factory image but got the same error but for a different app. I also extracted the boot.img from the factory image and flashed that, however I am still suffering from the same problem. Can someone please help me out?
I had the same problem :/ but i Use the nexus 7 toolkit to flash back to stock once in stock I rooted and then flashed recovery and flashed the update with no problem

Download the stock image file and extract the boot.img from there and place it in kerne_backup folder.

Nexus not boot up. its stock on boot loader
If you are trying to perform an upgrade to 4.2.2, then you would need the boot image from the version of the ROM you are upgrading from.
If you already have 4.2.2 (see your sig), why would you be trying to install an update package?
If you already have 4.2.2, but a custom kernel, you can flash the boot.img file from the Google distro a bunch of different ways, here's 3:
1) fastboot (unlocked bootloader):
- fastboot flash boot boot.img
2) ADB (with custom recovery running)
- adb push boot.img /sdcard/boot.img
- adb shell dd if=/sdcard/boot.img of=/dev/block/platform/sdhci-tegra.3/by-name/LNX
3) restore only the boot image from a prior Nandroid backup (twrp)
If you want decent help, you really ought to state:
- is your bootloader unlocked?
- do you have a custom recovery installed?
- if Yes (to the above question), did you make any Nandroid backups prior to the custom kernel install?

You are going to run into a huge amount of trouble if you don't understand the difference between bootloader and boot partition.
Perhaps it's just a language thing, but understanding the difference means the difference between a tablet which survives and one that becomes a brick.
good luck
Finally I using nexus toolkit and install fresh android 4.2.2 using image from Google dev web site and re unlock and root my tablet. After this everything working like before
I know this is stupid solution but work.

Custom Reovery failed to install OTA update

Hi All,
Want to OTA update my N7 3G (2012) to 4.4.2, but failure to update in TWRP.
Since OTA update not allowed in custom revovery, it any way to update it ?? Or I must wipe and fresh install 4.4.2 ??
Otherwise, is OTA update alloed in rooted device ?? (keeping stock recovery)
Thanks
OTA updates are possible with both, standard and custom recovery, but if you have done modifications to kernel / system most likely the OTA will fail. Or, if it doesn't fail after the update you will loose the custom recovery.
The easiest way to update is flashing boot.img and system.img (extracted from the appropriate Google factory image) by fastboot.

You can find a description how to do it on my blog, even if it explains haow to install Android 4.2, the steps are the same.
OTA's are crap. If you're rooted w/custom recovery there is never (IMHO) any good reason to take an OTA.

[Q] Nexus 4 kitkat 4.4.3 Update error

Hi,
I have been trying to update my N4 for quite sometime now and have had a particular issue every time. First I tried with the OTA file and adb sideload. Didn't work. Then this morning I received the OTA on the phone itself, tried doing it but still got the same error message. It says "Installation aborted. Error (Status 7)" I have no clue whatsoever what it is. Please help.
I am using stock rom, rooted.
P.S. if this has already been posted by someone else, kindly direct me to that thread.
Thanks
Error status 7 means modification to the /system directory. You must fastboot flash the stock 4.4.2 /system image only from the factory image package and then you will be able to sideload the update, all with no loss of data. This is what I did since my /system was heavily modified. After flashing the ota, re apply all your /system tweaks, if any.

Long story short I grabbed the stock ROM and flashed only the system. img to phone

Recovery versión?
Sent from my Nexus 4
Thanks a lot!
Hey, thanks for the info. One more question though, will fastboot flashing 4.4.2 system image remove all data? I guess the problem here might be because of Xposed Module, which might have made some changes in the system directory. The other issue that I am having is that I am unable to access any content on my laptop with my phone connected over USB, so i am unable to take backup of my data. I tried backup using recovery as well but it didn't work as well.

Flashing the entire factory image will delete all your data and return your device to pure stock, but we are not asking you to do that. All you need to do is flash the system.img which is located in the factory image which will return your /system partition to pure stock, and this will not delete any data because it does not touch your /data partition.
Xposed does modify /system and was most likely the cause for your ota error. You can try disabling xposed and flashing again, but if you get more problems, it makes the most sense to flash system.img and then flash the ota and re apply xposed.

yep, tried that. didn't work. I'll try the fastboot system.img solution and hope it works.

Nexus 7 grouper, manual update fails

I have a Nexus 7 (2012, grouper) which so far I have kept on 4.1.2 (JZO54K) using FOTAkill, but now I want to update to 4.2.2. I also have the latest CWM recovery (6.0.4.3).
I plan on applying successively:
094f6629314a.signed-nakasi-JOP40C-from-JZO54K.094f6629.zip
then
659e6288b87d.signed-nakasi-JOP40D-from-JOP40C.659e6288.zip
then
6ece895ecb23.signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip
Using ADB I tried to apply the first update, but it fails. I also tried applying it from /sdcard, but the same thing happens. The error message happens after "verifying current system..." and it consists of:
assert failed: apply_patch_check("/system/app/Browser/ProviderProxy.odex", "21a896ab...
E: Error in /data/media/094f6629314a.signed-nakasi-JOP40C-from-JZO54K.094f6629.zip
(status 7)
I tried downloading the zip update again, but it still fails. I downloaded it from http://android.clients.google.com/p...signed-nakasi-JOP40C-from-JZO54K.094f6629.zip
Does the fact that by bootloader is locked have anything to do with this error?
...and the answer is no. Even with bootloader unlocked, the update still fails with the same error.
FWIW I haven"t solved this. Can anyone help me, please?

I don't want android 4.3, 4.4 or 5 on it, I want 4.2.2. I cannot find any factory images for 4.2.2.
(edit) I was looking in the wrong place, I did find a nakasi image for 4.2.2. I will try that.
