updating nexus 7

Hello guys
I recently unrooted my nexus 7 device because I really want to upgrade to 4.2.1. I tried every possible way. My deice is unrooted, so I tried to update my it from settings, but it goes into custom recovery and saya...
"ClockworkMod Recovery v5.8.4.3
Finding update package...
Opening update package...
Verifying update package...
E: failed to verify whole-file signiture
E: signiture verification failed
Installation aborted"
So I said ok, it doesn't work, so I found the most recent update for the nexus 7 and downloaded it, went to custom recovery, found teh file and tried to update it manually.... This is what is said..
"-- Installing: /sdcard/Download/659e6288b87d.signed-n
akasi-JOP4OD-from-JO40C. 659e6288.zip
Finding update package...

Verifying update package...
E: failed to verify whole-file signiture

I guess my question is.. what can I do from here? I really want to update it soon

Just download the firmware direct from Google and flash it using fastboot. Easiest and most reliable method, though you do need an unlocked bootloader.

Can you please explain in detail?
From Google meaning their website? or from settings on the Nexus 7? and what do you meant by a bootloader? which bootloader should I use?

I'm not sure but i think if you want to take ota it might need stock recovery to install and to update manually from custom recovery I think you need the BIG update from 4.1.2 JO??? to 4.2 JO40C as the update from JO40C to 4.2.1 JOP40D is incremental if I'm not mistaken....also you may need to update clockwork mod

Download the update to your device(it's hosted on these boards) reboot your machine into recovery, and install from zip. It's the way many of us update our devices. There was no need to unroot your device. Your OTA failed to install because of the custom recovery you're using.

I'm using 4.2.1
How do u get the screen to not turn off

I've got the same issue.
CWMRecovery says the same thing when I want to update by OTA.
I tried to install manually the ZIP file (/cache) by copying it in my /sdcard with CWMR but I had the same script.
I'm rooted, in 4.2 (logic) with CWMR 6.0.1.9 no touch.
Do I have to restore stock recovery or a sideload flash (or fastboot) would work ?

I am using clockwork recovery. How can I change the recovery?

Follow the above link. It walks you through downloading a factory image from google and using fastboot to install it, regardless of what you may have done to your device. Also, if you are doing this, you can go ahead and use the latest image if you want, which puts you at 4.2.
enjoy. :good:

[Q] Nexus 4 won't upgrade to 4.2.2 in any way

[Q] OTA failed and displayed dead Android saying Error! Tried to sideload the zip file using Toolkit 1.6.8 and it didn't go through. Tried to load it using TWRP and this is what I get:
Code:

I'm running rooted stock ROM, never tried anything else so I don't know how I could have messed up something.
Thanks for any ideas!

Flash a stock rom and install the OTA through adb sideload with adb and not by a toolkit, worked for me. After that reroot. Also read this thread well http://forum.xda-developers.com/showthread.php?t=2145848.

Did you try a different kernel in the past? ie Franco's kernel?

No, never. I just wiped the phone and installed stock 4.2.2 using the Toolkit and now it won't boot.
EDIT: I guess that's because the Toolkit doesn't support 4.2.2. Oh well just flashed it using ADB. Hope I can get all my app data back...

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.

[Q] help with (Status 7) error when flashing 4.4 update

so I was so elated to finally have KitKat. I downloaded the update from one of the sites linked in the General Forum for the Nexus 7, and attempted to adb sideload it. This is what I got:
Verifying current system…
“/system/etc/audio_effects.conf” has unexpected contents.
E:Error in /tmp/update.zip
(Status 7)

What do I do?
Thank you for your help

Should I try to download again? It seems as though I have some sort of audio that messed it up.

i had the same problem
i downloaded the lastest 4.3 image from google (https://developers.google.com/android/nexus/images#nakasijwr66y)
you must have a clean and fresh install of it.
trying to flash this via CWM or TWRP recovery failed.
so i extractet the image and used the "flash-all.bat/flash-all.sh"
all user data were gone (i dont care about at my tablet ) but so a could flash the rom.
after that i could flash the update to 4.4
oder esyer now. flash the stock 4.4 image

I've attached the original file I extracted from the 4.3 stock image (nakasi-jwr66y-factory-1e503532.tgz).
You can try copying it to /system/etc/ (ensuring permissions are correct) and then retry the installation.
I suspect that if you've been playing around with audio tweaks then it's going to fail on other files too.
If it does, then you can use fastboot to _just_ flash the system.img and you won't lose any of your data.

Same thing happened to me. But it's worse, it's stuck on bootloader and Windows won't recognize the device (unkown device on device manager) so I can't even use adb to flash factory image. I'm really desperate here, anyone here with a tip?

Use Wug toolkit to install drivers (it has a couple of possibilities) until it works, then install factory image.
I got it to work on windows 8.1, so it's possible.

I'm having a similar problem. I tried to adb sideload 4.4 that I downloaded from the google website and got an error. Now my nexus 7 is bootlooping at the google logo and returning to twrp shortly after. I can't seem to use fastboot and I've wiped everything. I'm also on a Mac. Any help would be greatly appreciated. I can't seem to figure out a solution.

There's your problem. You have no /system/build.prop file.
Did you delete it? Have you a backup? You need to get it back on the device.
Edit: I've attached the build.prop from the N7 2012 (nakasi/grouper) JWR66Y ROM.

Just use something like Root Explorer to copy it from your SD card to /system/ (and check permissions are 644 or rw-r--r--).

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.
