Then remove it and restore the files you changed in system/app. (BrowserProviderProxy.apk/odex)
[Nexus 7 General] WooHooGuy:
Same here on my Grouper Nexus 7.

I upgraded to 4.3 JWR66V by making sure SuperSU was up to date, flashed stock recovery using Wug's NRT, then triggering the upgrade from the system update menu.

Everything went fine, still had root and didnt need any nandroid backups I made.

Since then the security update has been released so I flashed stock recovery again, then applied update via system update menu.

I got a error picture on the stock recovery screen, but on reboot the system "optimized" all the apps and everything seems fine, system update check states everything is up to date.

Is the update supposed to change the build number?

---------- Post added at 07:53 PM ---------- Previous post was at 07:28 PM ----------

While toolkits make things easier, there still needs to be proper user input and setup of them to ensure they work properly.

Did you make sure the default device settings in Wug's NRT was properly set to your device? Was the current build number correct for the actual device and not the build number you were flashing to?

There are two different Nexus 7 tablets -

Grouper - Wug's " Nexus 7" menu selection

Tilapia - Wug's "Nexus 7 v2" menu selection

When properly set Wug's NRT makes sure you have the proper files files needed for flashing and makes all the difference in the world.

Simple rules to follow-

Always make sure the toolkit is up to date before use.

Make sure you are using a good quality and tight fitting USB cable.

Always make a nandroid backup before OTA upgrading or flashing.

Make sure you flash stock recovery before applying updates.

Make sure you flash stock kernel if you installed a mod or ROM that modified it, or possibly modified it.

Have you tried the Steps outlined in Wug's NRT to recover a soft bricked device? There are instructions on youtube on how to remove the back cover of the Nexus 7 and pull the battery terminal for a hard reboot if needed. If you get it to bootloader mode flash the last known build that your device was working on or a Nandroid backup if you have one.

So I got notice of system update to 4.3, I was already on 4.3. Rooted with TWRP recovery. Went ahead and did update and booted to TWRP and installed update. When it was done I got notice from TWRP that install was OK but seemed to lose supersu rights. Had choice to leave it or fix supersu, I choose fix supersu. So then rebooted, all works OK and supersu still works. Don't see and change in about tablet and still have TWRP recovery??????
[Nexus 7 General] slybunda:
where can i get those files from? i dont see any backup files in there.
[Nexus 7 General] choybel:
Using Gitah's suggestion, my device detected an update available, so I went ahead and install it. My device rebooted to twrp, installed it and there was no error. I restarted my device excitedly and happily but when I checked my device is still in JWR66V...

So I re-installed SU and went to adb shell and typed $ su, then it said not found...what am I doing wrong?:confused::(
[Nexus 7 General] Gitah.:
You should always make a backup if you edit some system files. You can try mine but I don't know if they'll work since they're from 4.2.2.
[Nexus 7 General] moses6533:
Yes everything was set correctly on the first go around, and was running stock 4.3 JWR66V rooted. The only thing that i did before that which may have effected it was i first flashed back to stock recovery to attempt to get the update via the OS under system update....it got about half way then the android died (fell on his back with a red exclamation mark). So obviously it was time to move onto to wugs toolkit. So i updated everything even ran the driver test, and everything was going smoothly, so i hit flash stock + unroot, and the command prompt said "wait 5-10 minutes for your to device to reboot"

Needless to say i waited and waited and nothing happened, so when i hit START i got the BOOT FAILED. and so then i tried and tried again with the toolkit to no avail, i was always stuck at the fastboot, and could only power off or restart fastboot, could not go to recovery or start. Temp boot to TWRP said no OS found, so i just used the FASTBOOT COMMAND PROMPT in the WUGS directory to load the images from the official update. That worked, and the only snafu was that it wiped EVERYTHING, i didn't think that it would even wipe backups, because i didn't flash the userdata image. On side note, my same wallpaper was still there. :p
[Nexus 7 General] tcat007:
Seem to be getting a lot of different results here going from 66V to 66Y. I just disabled the upgrade notification and sticking with 66V until a reliable method is posted. Rooted with NRT, M-Kernel, Chainfire SU, why fix it if it ain't broke.
[Nexus 7 General] Fotogravin:
I bet you did fastboot update -w ***.zip ;) -w tells fastboot to erase all userdata...
[Nexus 7 General] walpow:
Yeah, it does seem to be a crapshoot. I'm rooted, TWRP recovery, stock ROM, and the OTA looked like it was going to work until suddenly Mr. Android Man was on his back next to a big ERROR. I ended up flashing the 66Y system partition (my first flash - yay, me!) with the WUG toolkit and rerooting.

By the way, this silly little update was a lot more trouble than the original 4.3, for which the OTA ran perfectly (though I did have to reroot).
[Nexus 7 General] rtiangha:
Hi everyone.

I've had multiple hardware issues with my Nexus 7 wifi lately, but received a new battery and all is fine now. I'd like to OTA update to 4.3 from 4.2.2 without losing data and I'm rooted and have TWRP installed. The problem is that my USB port is busted (I've been charging using the Nexus dock), so I can't connect this thing to a computer via USB.

My understanding is that I'll lose root and recovery after upgrading to 4.3 without taking any precautions, correct? I really don't want to lose root since I'll have no way to re-root after the fact, but I was wondering if this would work:

- Boot into TWRP

- Install OTA zip from 4.2.2 to 4.3 in TWRP

- Re-flash SuperSU

- Reboot machine

- Re-install TWRP through goo.im

Would that work, or is there a better method? For example, should I attempt to edit out any offending lines in the update script of the OTA? Is that a better option? Or am I simply hooped? And dumb question, but is there a way to re-flash TWRP from within TWRP before I reboot?
[Nexus 7 General] osm0sis:
You won't lose twrp as long as you reflash the latest SuperSU before rebooting. :good:
[Nexus 7 General] WooHooGuy:
+1 on making sure SuperSU is updated before you attempt the upgrade, Be sure to launch SSU and do the proper binary install at the prompt.

You may want to use the option that exports the "update.zip" file first so you can fall back to it if by chance anything goes wrong, then go back and trigger the install again writing to the system partition the second time.
[Nexus 7 General] goldenval:
Hello society. My turn to ask for help. My story in pictures:

1. My version of Nexus7:

2. So from 1st page of thread I downloaded JWR66Y from JDQ39 version

3. When loaded rom onto internal memory switched into TWRP:

4. Started installation from location where I stored rom:

5. And got error: (sorry last picture is bad, almost readable)

So, where am I wrong? I read all 60+ pages of the thread, but no answer for me found. Thanks!
[Nexus 7 General] Fotogravin:
Read the error: signature verification failure. Toggle the check verification (don't know exactly where you can find it in TWRP, probably in Settings) so it doesn't verify signature and try again
[Nexus 7 General] goldenval:
Thanks for advise. Yes, there's one tick in general settings, which I unticked:

and another one in the page where I'm applying actual rom, which is also unticked:

but unfortunately it still gives error, this time different: radio can't mount. I went into settings where I can select what to mount but radio isn't selectable there to tick. So, is this problem with TWRP, I wonder?

BTW, am I taking too much space here with my pictures? Can somebody show me how to hide pics. Thanks.
[Nexus 7 General] FReaKRaNT:
Also out dated tarp version.

Cheers, FReaKRaNT
[Nexus 7 General] goldenval:
Thanks, I also noticed this. Updated my TWRP to latest version (whatever came in OTA) & tryed it again. So, now it's giving brand new eror, please have a look:
[Nexus 7 General] FReaKRaNT:
I would re d/l the file.

Cheers, FReaKRaNT
[Nexus 7 General] fozzie:
You've edited the build.prop file so it's not the same as stock & so the check is failing. You either need to remove the changes or get a copy of the stock one and replace it.
[Nexus 7 General] goldenval:
Do you mean download from XDA to my Windows7? It'll take me about an hour with my slow internet. I re-downloaded loaded ZIP from PC to Nexus7, this time into root location of memory - got exactly same error as last time... However re-downloading full zip from XDA again. Will reply not soon.
[Nexus 7 General] fozzie:
You don't need to re-download the update. That was wrong advice. Read my last post.
[Nexus 7 General] goldenval:
that's right, remebber this. I wanted to change icon's size - so changed my build.prop. However .bak file is kept. And I accidentally deleted modified build.prop file. So, now I can only enter into recovery & original build.prop.bak file is there. Should I better reflash 4.2.2 via windows7 PC? And then come back to 4.3?

few hours later update:

Thank you all. Got updated to 4.3.
[Nexus 7 General] choybel:
Since I still can't get it to work, I'm now seriously considering reflashing everything back to stock, but it occurred to me that maybe I should try uninstalling some apps first, mainly those that required rooting to be installed, but that's also going to be a tedious process for me since I would have to re-install them, and again I feel that it would really be beating the purpose. So, just a quick question, do I need to uninstall busybox before doing the update?
[Nexus 7 General] fozzie:
Nope (& the 'most' you should have to do is dirty flash just the system partition of 4.2.2).
[Nexus 7 General] choybel:
I'm already on stock 4.3...i just want to install the latest update via twrp, but I can't get it to finish successfully. It just says, something about set perm error, some changes failed or something(sorry,forgot the exact line :-\ )...
[Nexus 7 General] fozzie:
Typo/tired, sorry. Meant 4.3. I know what the problem is. You just need to chattr -i one of the startup scripts that SuperSU modifies then you'll be fine. Lemme just find it....

---------- Post added at 11:08 PM ---------- Previous post was at 11:05 PM ----------

chattr -i /system/etc/install-recovery.sh

Run the update and then flash latest SuperSU before restarting.
[Nexus 7 General] choybel:
I'm new to all this stuff so please guide me step-by-step. I'm really sorry but I promise I'll get better. I'm actually learning things here and I really appreciate every and any help I get.

So, let me try to enumerate the steps:

Uninstall SuperSu via full unroot in the settings

Reboot to twrp

Open adb shell??

Type the command u gave

Run the update

Re-install supersu
[Nexus 7 General] fozzie:
Don't uninstall SuperSU.

Run the command in Terminal Emulator on the phone.

Boot to recovery.

Flash the OTA update then SuperSU.

(All on the device. No need for ADB.)
[Nexus 7 General] yuvi_r:
does not work for me

I'v tried to replace my debuggers file with the one that you used and then use the grouper.zip, but still getting the assert failed: apply_patch_check("system/bin/debuggers" error
[Nexus 7 General] choybel:
It says permission denied...what's next pls?
[Nexus 7 General] fozzie:
What does? Did you type 'su' in terminal before running the command.

(I think we've gone off topic enough now. There's plenty of threads about applying this update. I'm also concerned from what you're asking that don't really know what you're doing and so you need to do more research and reading before you break your phone.)
[Nexus 7 General] choybel:
Ok,didn't know I had to type su first.tried it,and then entered the next command, rebooted to twrp to install update and still got the same error.Anyway, I will search for other similar threads as you said. Thanks!
[Nexus 7 General] eliboy:
How can i disable OTA?
[Nexus 7 General] rhyang:
Make sure it really got replaced by looking at the debuggerd checksum -- the OTA update script is complaining that the expected checksum of the file does not match the actual checksum. You can see the expected checksum by looking in the grouper.zip at the update script, search for debuggerd.

Hey guys I've got a nexus 7 (2012) wifi how do I tell which one I need to download? I'm on cleanrom 4.0.0 atm and do I just flash the file in TWRP?
[Nexus 7 General] fozzie:
None off them; they're for updating stock ROMs.
[Nexus 7 General] robgee789:
Ahh ok cleanrom is stock based if that's what you mean but if not how do I get back stock mate?
[Nexus 7 General] fozzie:
It needs to be 100% stock as an update checks all the files in the ROM.

I'm not sure what you're trying to achieve as your ROM developer should release an updated ROM based on the latest Android version.
[Nexus 7 General] robgee789:
I think he has moved on to a different device mate so there won't be any more updates so I was thinking of going back to stock to see how it runs
[Nexus 7 General] TheGoD:
Thanks, I actually know that but realise now that I totally messed up that sentence. I actually wanted to update to the latest stock before installing Paranoid Android. Anyway I eventually managed that so thanks anyway.

are we getting the new build of 4.3 that the 2013 N7 is getting?
[Nexus 7 General] oldblue910:
Nope. The N7 2013 is on a totally different branch. That JSS15R OTA contains nothing but device-specific stuff for the 2013 N7. I'd imagine when KitKat launches, that will be where they merge the 2013 N7 with the rest of the device trees.

[Nexus 7 General] aznxk3vi17:
For those of you who flashed back to stock and have no custom recovery...

adb reboot recovery

When you get to the Android with a red exclamation point, press Volume Up and Power at the same time, briefly, a recovery menu should appear

Volume down to "apply update from ADB"

adb sideload "file"
[Nexus 7 General] holysmokesbatty:
I'm also seeing reports that it is flashing without trouble on the latest CWM.
[Nexus 7 General] aznxk3vi17:
It's a signed zip so it should flash fine on any recovery, but I figured many people in the Toolkit day and age aren't intimately familiar with adb sideload.
