[Q] JWR66Y breaks root and recovery??? - Nexus 7 Q&A, Help & Troubleshooting

I was running 4.3 stock rooted and yesterday was prompted to update to JWR66Y, thinking this would be no big deal i decided to update. later on that day i decided i was bored with stock android and went to flash cm10.2, but the update has seemed to wipe TWRP off my nexus 7 and has also broken root..
does anybody know how to fix this??? the internet has provided no answer and i would very much like to enjoy the freedom of having a rooted nexus..
thanks to anyody that can help! :fingers-crossed:

If you had searched well you knew that booting a stock ROM after sn update almost always replaces the custom recovery by stock recovery. The easiest way to reflash your custom recovery is using fastboot, I.e.
fastboot flash recovery <recovery.img>
while you are in fastboot mode.

This did not work for me unfortunately. I tried to fastboot flash both latest TWRP and CWM. Neither one sticks and it's pissing me off.

You should be able to use fastboot to flash a recovery img or use a toolkit.

This is a problem many Nexus 7 owners are experiencing since the 4.1.2 update, whether by OTA or flashed from sd card. There apparently is an issue with the bootloader (version 3.43). One solution that I have seen on t his forum and on another is to flash the last version of bootloader (3.31 I think). I have tried every conceivable method to get into either stock recovery or custom recovery to no avail...flash, 2 different toolkits, ROM Manager, TWRP...you name it, I've tried it to no avail. I have not tried to flash back to the old bootloader though...just doesn't sound like a good idea...although I have not heard of problems being encountered by those who have flashed the old bootloader...yet. There are a couple thread in this sub forum on the subject if you want to read the 100 different ways users have tried to get a recovery.

I found this and I didn't tried it because it may not work see for your self
I just wondering when the android 4.2 will be released to solve all those problems
Sent from my Nexus 7 using xda app-developers app
I think my bootloader is 3.41 and I have no issues but I flashed the factory image from Google because my touchscreen didn't respond after the 4.1.2 OTA.
Try flash the bootloader and see if it works and if not then flash the factory image.
Just note that if you use the script/batch file to flash it all automagically it will wipe your SD so flash each image separately and don't flash userdata.img
flashing factory fixes any software problem, its the best thing about owning a nexus.

weird soft brick... help please

I flashed the clockworkmod touch zip from my recovery.
It didn't give me the touch recovery, I thought "whatever" and booted back into my rom.
It wouldn't boot.
I went back into recovery and flashed PA rom and gapps.
They weren't booting, I decided to give them a few minutes.
It finally booted.
It no longer connects to wifi or tmobile.
I can't transfer files over usb.
Wugfresh's toolkit couldnt return it to stock.
I thought the recovery might have gotten messed up when I tried to flash CWM touch, so I flashed TWRP from Wugfresh's toolkit.
I used adb sideload to flash a stock rooted rom.
It still took forever to boot, and is still not connecting to wifi/network.
TL;DR I can boot into fastboot and recovery and even the rom but I have no network connection... help guys :'(
It says BASEBAND VERSION - N/A... could that be the problem? If so, how do I fix it?
This is why we don't use toolkits. Return to stock using ADB and do it again...

When I try to fastboot flash the stock image it says "does not contain recovery.sig" "does not contain boot.sig" and only updates the bootloader.

4.3 Factory image with custom recovery?

I apologize for the noob question but I've never found myself in this particular situation...
I've decided to stick with the 4.3 JWR66V factory image while I wait for a working rooted version to be released or even an updated SuperSU or Superuser zip (that doesn't drain the battery or lose root with certain apps).
I used the factory image found HERE and followed the detailed instructions found HERE. I followed the instructions under section "D" vigorously which meant that I installed the stock recovery image as well. Everything is running as it should. However, I was curious if it was safe to flash TWRP 2.6.0.0 recovery through fastboot with my current setup. I'd like to use that recovery to wipe cache/dalvik and possibly fix permissions. However, I'm not sure if this will break something so I am hesitant to try it.
I have made sure the bootloader is unlocked. But I am curious if it's safe to flash and use TWRP while I am not rooted.
You can install recovery with no problem, root has nothing to do with it. however i think upon a reboot your recovery will be replaced with factory.
Interesting. I wonder why/how the system would flash back to stock recovery if I've pushed the TWRP recovery image over the factory image?
I flashed twrp from fastboot and it's still there. Just waiting on root

Without root would there be any functionality within TWRP that I shouldn't touch? Or does recovery functionality have no dependency on root?
What is there you wanna do? I just replaced stock with twrp so I can just flash the su zip when its out because I don't always have access to a PC. Also, Franco released his initial 4.3 kernel which I'm thinking about flashing.
When rebooting from twrp it'll ask if you wanna flash the su.apk because you don't have root I chose no because it wouldn't do anything for us right now without the binaries
Sent from my Nexus 4 using xda app-developers app
Good point. As of right now I guess I don't have a huge need for it. I'll just leave everything as is until a proper SuperSU is released. At which point I'll install the latest TWRP and root.
Just a question, wasn't nexus root toolkit supposed to be able to revert to stock?
I did it in previous android versions.
now I am running slim rom with CWM and "reverting to stock 4.3" using NRT doesn't work, the process finishes but nothing is done.

No idea. I use a Mac and flash back to stock via Fastboot. You should just learn to do that anyway so you have a better sense of exactly what is going on and if something fails you'll know exactly which step is failing in order to correct it. Relying on a toolkit is like never taking the training wheels off your bike.

Or CWM
If you want it that bad. Just download the factory image from Google devs and flash it.
Then you also have stock ROM running.

Is there any way to revert back to stock recovery in order to get the update?
Further more, is there an option to do so without re-flashing stock all together?

You can extract the stock recovery from the factory image and flash through fastboot.
Hit thanks if I helped.

You can get the stock 4.2.2 recovery from the 4.2.2 factory image. I did have it but as I only keep the current factory image I only have the 4.3 recovery to hand

OK, did some further investigations and here are my findings
1. If you have it, you can use Wugfresh's toolkit (V1.6.4 for now) and it has a utility that can simply restore stock recovery and if you want it, stock kernel as well.
2. The Toolkit will download all necessary files and prompted you before each step.
3. It will revert back permissions for the stock recovery as well
I'll give it a try later on at home.
Thanks guys

I am a bit confused. According to the “Nexus OTA Help-Desk” thread, the way to do this is as follows:
Scenario #2
You are stock, with root. Custom Recovery without any modifications or deletions.
Continue to Section B
Section B: Flashing in a custom recovery
1) Download the OTA.zip and copy to your phone.
2) Boot into recovery
3) Flash the OTA
4) Flash Su.zip: (SU is being updated often so check Chainfire's G+ for the latest) https://plus.google.com/+Chainfire/posts
NOTE: Root on 4.3 is not stable. Your mileage may vary.
5) Reboot
So, what is different about using this method to install the OTA and just running the OTA from the notification, and is this the incorrect method?
Is returning to the stock recovery the preferred and more or less foolproof method?
I'm not sure why there's people saying otherwise, but from my experience you don't need stock recovery to take on an OTA...
I've updated my N7 several times now from when I first bought it to 4.3 currently, all the time with a custom recovery. Unless you've changed some other files which causes an error during the OTA update, I don't believe there is a need to re-flash stock recovery at all.
@mlj11, lots of people have the OTA failing on them, even if they are on rooted factory image 4.2.2.
Why the OTA fails on rooted 4.2.2 is still unclear.
My N4 with rooted factory image 4.2.2 also updated like it should without error.
Maybe the unlocked bootloader is the issue letting the 4.3 OTA fail.

@DecypherT
I'm not saying that rooted users will have no problems updating. My post was in response to people on this thread saying that a custom recovery will stop the OTA. This is false.
It can't be the unlocked bootloader (and it has never been) causing the problem otherwise you or I wouldn't have been able to take the OTA, for example. More likely it's something else.
If any of a user's system files have been altered, there's a good chance the OTA will fail. In the past that happened to me because the Stickmount app changed one of the system files. Once I replaced it though, I could update without any problems.
Ok, good points you're proving here.
Still, it looks like the (OTA) android 4.3 is very unstable.
I'm on rooted 4.3 and experience no big bugs or flaws though.
I do see a very large decrease of battery life when using the phone (screen on) and a big increase when in deep sleep. When the phone is off I almost use no battery.

No you need stock recovery. You can easily flash stock recovery using wug fresh toolkit then you should be fine
Sent from my Nexus 10 using xda app-developers app
You can flash the 4.3 images manually in bootloader and keep your current recovery.
That's pretty much what I did. I updated twrp with goo, then flashed the stock rooted 4.3.
