I have an unlocked and rooted stock Nexus 7 with the stock rom. I Just performed an OTA update to Android 4.2 and now the Nexus is stuck on the Google splash screen with the unlocked padlock symbol. I have tried booting to recovery with the Wugs Rootkit and it shows a an android with a red warning triangle above it. Please can anyone help me to fix this.
I have a PC with Wugs Toolkit 1.5.5 and I have the Google Nexus 7 Root Toolkit 3.2.0.
Please anyone know how to the fix this as I have no idea.

I have the exact same problem. For the record I had the very latest version of SuperSU Pro that got updated today (0.98, I think) with survival mode activated. Don't know if that's the cause of the problem or just the fact that it's rooted.
Dang. Same thing here. And I also just installed the new SuperSU before applying the OTA.

Well, since you replied, this thread is now at the top of the stack, so there's nothing above it. I'm getting old and blind, but I don't see a thread and can't find one with search called anything like "Stuck on Google Screen". Except this one, of course.
Edit...Eh, nevermind. I just flashed the full 4.2 from Google instead of mess with this any more. Restoring apps now.

I did exacty the same thing the app had already updated before I could do the Android 4.2 update. I fix the isue. I had to do restore to stock Rom 4.1.1 then update to 4.1.2 and then to 4.2 then recovered some of the stuff I lost with an old Titanium Backup I did a few weeks ago.
Recovered mine
Hi all,
(I'm the second poster)
I managed to get my Nexus 7 back, although losing all the data, which I think cannot be avoided.
Here is what I did, for dummies:
- Reboot into fastbood mode. For this, hold the power, volume up and volume down button.
- Use the Nexus 7 Toolkit (I donated to get the latest version) or the Nexus Root Toolkit (which I guess works as well) and flash the google factory stock rom.
- If using the Nexus 7 toolkit, at the beginning I selected that I had Android 4.2 installed.
- After flashing, my tablet was as if just taken out from the box (but still unlocked). All my old apps got downloaded automatically, although the settings / game progress were not saved. Fortunately I have some Titanium Backup backups from a little while ago.
- After all apps got downloaded, I put the tablet in fastboot mode again, and I rooted it with the Nexus 7 toolkit via option 4 and then sub-option 2.
Sorry if I said some obvious stuff, but I am not an expert, and wanted to help other non-experts
Good luck to everyone.

Before doing all that, plug your Nexus in and make sure USB Debugging is enabled, and also its set to camera mode, not MTP.
Goto command prompt, and use:
adb reboot recovery
You will then see the Android with a red triangle, at the same time quickly tap power and volume up, you'll then be taken to a blue screen.
Choose wipe cache.
Also you could factory reset?
Then reboot
Hope this helps.

Sure First I thought about using Wug's Toolkit, but I saw it was not updated yet to handle Android 4.2 stuff, whereas the Nexus 7 Toolkit was.
You can download it from http://forum.xda-developers.com/showthread.php?t=1809195, but only version 3.2.0 which does not have Android 4.2 stuff. To get the latest version (3.8.2, updated yesterday 14 november), you have to donate and wait until the developer sends you a key. I donated 5 pounds but the developer says any amount is OK. I got my key 1-2h after donating.

Well, I can only tell you the situation that I had before installing the 4.2 OTA:
- Unlocked
- Stock Android 4.1.2
- Rooted with SuperSu 0.98 and survival mode activated
Maybe the problem was to be rooted; or to have SuperSU; or to have specifically SuperSU 0.98; or to have survival mode active... I don't know.
If you want to be fairly sure to not have any problems, I would uninstall SuperSU. There is an option to do a full unroot inside SuperSU itself. Maybe before that to be even safer, you could even uninstall all the root-requiring applications?
Then, reboot, apply the OTA, and cross your fingers
Then you can root again with Nexus 7 toolkit, it was done very fast, and you will have supersu again.
Rooting or unrooting should not wipe your data.
From now on I think I will not have the survival mode activated before an OTA, just in case, as I now know how to unroot / root quite fast.
Good luck

I didn't bother with reverting to stock. I just booted into fastboot mode, which I was still able to do, and installed the factory 4.2 image from https://developers.google.com/android/nexus/images. I develop apps, so I already had a full development environment and the needed tools installed.

Has anyone figured this out yet? I'm also stuck on the Google boot screen after installing the 4.2 OTA on my stock, rooted Nexus 7, and I've tried the following:
- Wiped cache.
- Re-flashed the 4.2 OTA (build JOP40C) from stock recovery via adb.
- Flashed TWRP (via Wug's Root Toolkit) and renamed Superuser.apk, assuming that was the issue.
- Re-flashed the 4.2 OTA (build JOP40C) from custom recovery via WugFresh's Nexus Root Toolkit v1.5.5.
Nothing worked -- it's still locked up on the Google screen at boot. How do I fix this (ideally without wiping my user data)?

Same here, didn't try all you did.
I'll try to descibe what I did to see similarities,
I had my N7, Rooted 4.1.2, unlocking via face-lock, , I has just installed last update from super su, had root protection enabled,
I'm willing to pay 2.7 Bitcoins, (~31$) to someone helping me fix it without reinstalling everything.
Just an update on my situation: Since adb still worked from the Google boot screen, I managed to batch pull my TitaniumBackup folder down onto my PC. I went ahead and flashed back to stock (good guide here, for anyone who needs it: http://forum.xda-developers.com/showthread.php?t=1781250), updated, re-flashed SuperSU and Busybox, and restored all my backups without any issues.
First time I've actually had to do that, but I'm happy to see that my daily TiBu backup schedule paid off, and I'll probably feel much more confident repeating the process in the future.
Anyway, I'm assuming the issue had something to do with the SuperSU apk, as others here have guessed. I, too, had SuperSU's survival mode enabled (which I've disabled) -- and I also had OTA RootKeeper installed (which I've now ditched), In the future, I'll probably just err on the side of caution and fully unroot before applying an OTA; it's easy enough to just re-root, rather than rolling the dice with any sort of survival mode.
And if SuperSU ISN'T the issue, I'd sure like to know what is!
Hi guys, my girlfriend updated to 4.2 yesterday, and it was fine up until her battery died. so she charged it and then tried to turn it on, and it was in an endless boot loop first starting with the google logo coming up, then itll go kinda staticy and go to the X (and sorry for my future description) but then the screen will look like its in the matrix? If that makes sense. I can provide a picture if needed, but then itll just reboot and do the same thing over and over again. We went to Virgin and called samsung and they both said the same thing that the system would have to be recovered. Virgin, however directed me over to use Odin. I've never really used Odin before and am not sure what to do, so would someone mind helping me out with this issue? i've tried going into recovery menu as well, but it doesn't work. I really appreciate the answer in advance!!!!! Her phone is the galaxy nexus.

AdmiralAqbar, if you need to return your Nexus 7 to stock, follow this guide: http://forum.xda-developers.com/showthread.php?t=1781250
You could also boot into recovery (hold Volume Up and Down keys while you power on, then select Recovery from the list), and then try to return to stock from there (in Recovery, press Power and Volume Up at the same time, and there should be an option in the resulting list).

I didn't even realize this was a nexus 7 thread i'm sorry! I just noticed the same problem so i clicked into this thread haha, she has the Galaxy Nexus i9250.

I just got the OTA update to Android 4.4, and being eager to get it installed, hit the install button right away. I told a few people I was going to be a few minutes while installing the update... and tapped the button.
That was three hours ago, roughly.
I'm on a rooted nexus 4 with CWM Touch edition installed as a recovery. I don't know exactly what version right now but it was the latest when I installed it a few months ago.
The install launched CWM, and I waited as the loading bar filled. Right at the end it gave an error message - in a panic I didn't take note of what it was, hit the onscreen buttons and went through a window telling me I might have lost SU permissions - which I told it to fix. The startup animation (with four dots, the new 4.4 animation I guess?) started... and continued for more than five minutes.
I was still panicking and instantly launched back into CWM, downloaded a (I think correct, checked it multiple times, as on does...) update zip from the web, and flashed it via adb sideload. This gave me an "Error 7" and a failed install. I tried again, same result. Then gave up and hit the restart button in the hope that one of the attempts had indeed worked...
I now have a Nexus 4 sitting on my desk playing a nice dotty animation, and it's been doing that for fifteen minutes as of now. I'm intending to leave it as such hoping that it will actually turn on and it's just having a very long boot.
So, the question. Anyone have any ideas how to save my Nexus?
I'd rather like to end up with the data on the device intact (stupidly did not back up before installing and can't get any files off it until an install works) and possibly with Android KitKat running on it, as was the original aim of tonight, but if neither are possible, I'd at least like to end up with a functioning phone... just with any stock rom.
Thanks in advance.
P.S. I'm not new to flashing ROMs manually - my last phone was a ZTE Blade which never ran any ROM well, so I must have flashed on that phone at least ten times, including via ADB.
Ignore the above - I fixed the problem by using fast boot to flash the stock rom from developers.google.com/android/nexus/images ....
I feel really stupid now. But it worked perfectly. All I did was open the flash-all.sh and copy the commands out line by line, but removing the -w from the final command to dodge wiping the device. Anyone confident in Terminal or similar should be fine
Sorry for the thread being created but I really thought I couldn't fix this xD

Your post saved me from a complete wipe and reinstall, so thank you for sharing your fix. I had a very similar issue but my Status 7 appeared to be because of my previous root and the new install not being able change the permissions on some /system files.
Now I just need to re-enable root via the NRT.
at least you've learnt something. Ota updates will always fail if you have any cwm recovery installed. Not like it hasn't been discussed before. Guess you won't be making that mistake again.

To be fair, there are several posts around where people have simply updated their version of CWM and then reported the 4.4 upgrade has worked. I think I must have used the OTA Rootkeeper before as I don't recall these issues (other than losing root) during the 4.3 upgrades.
I'm in a similar boat.
My wife accepted the OTA update with TWRP installed and ended up in a boot loop. We didn't care about the data on the device, so thinking I could start from scratch, I did an Advanced Wipe of everything in TWRP. Now the phone has no OS on it.
I tried doing an adb sideload KitKatNexus4.tgz, but it gives me an error of a corrupted .zip every time.
I'm stumped.

Sideloading is only for flashable zip packages, not official factory images that required using fastboot. Use the guide links in my signature for instruction to flash factory image.
Or you can use sideload to flash flashable stock roms: http://forum.xda-developers.com/showthread.php?t=2527806
Unless your wife is really into flashing, I suggest just leaving it everything stock.

where did you find these posts? the only thing that I'm reading is people constantly saying "CWM will break OTA" or "you can't flash OTA with custom recovery" (this is clearly wrong)
I have the latest CWM recovery (6.0.4.3) and I don't want to lose it or flash stock recovery and CWM back. with 4.3 I remember that everything went good and I didn't have a lot of problems, the only thing I had to do was to unroot before flashing the OTA from CWM... but this time I'm reading a lot of conflicting posts so I'm a bit worried to try this by myself without some sort of feedback from any other user

It will softbrick the device, or atleast fail. I don't even have to try CWM, but with TWRP, if I make any changes to the /system partition it failed. I suggest you just flash a stock 4.4 rom: http://forum.xda-developers.com/showthread.php?t=2010887
I panicked and probably did something quite stupid...
So I tried to flash the new cyanogenmod rom to have a taste of kit kat, but then I had the status 7 error.
This never occurred to me before, I didn't keep a backup to fall back onto... ( yes, I am an idiot, I learned my lesson, the hard way)
Than the device won't boot, it shows the Google logo twice, and then goes into the clockwork mod, where you choose to flash roms
and I am stuck.
I tried Nexus Root Toolkit, doesn't help because my device is not booting up, no way can it install the drivers properly...
and I think I did something more ingenious... I just tried anything on the Toolkit, and I got my rooted Nexus 7 locked...
But it's still the same, I am stuck at the clockwork mod thing just as before... Wiped whatever I can. and even formatted the sdcard and system...
Some Android Wizard out there... Please help...
If at boot you go to recovery directly... You have had to flash new version of recovery in wrong partition. You must flash it last version of recovery with "fastboot flash recovery yourrecovery.IMG" (see 'recovery' as partition to flash). Then flash boot and system partitions from factory image (in XDA have you multiples threads about it) if you want to keep your data. If not, flash factory image from usual ways (this wipes your data) and then flash recovery like I say above.
After that, try to flash CM again.
PS: I recommend TWRP instead of CWM.

make sure you look for "android tool kit"....
This is the third time trying to write this without my computer blowing up, so I'll be short. After five months of not using my N7 for certain reasons, I came home to update it to Kitkat as I was unable to do so before I came out. The OTA downloaded fine and, like updates before, I clicked install. Sadly, this time the installation did not work correctly, and I stupidly forgot to grab the error code that was thrown. After the failed installation, it went into a bootloop using the new boot screen, and with the boot screen graphic glitch I've seen other people complain about. I can get into Recovery Mode easy enough, which is running ClockworkMod Recovery v6.0.2.3. The bootloader is also unlocked. I've tried to do a factory reset from CWMR, but it hasn't helped.
I've gotten quite rusty with my skills in this work (as if I had any in the first place), so I thought coming here would be a good idea. Any thoughts on how to get Kitkat on working and proper?
nexus root toolkit
Download nexus root toolkit or unified android toolkit to your PC .Install drivers etc and do a factory restore using the KitKat factory image or the restore options in the toolkit

Thank you so much! Took a few minutes to figure it out, but my N7 is back up and running!
Hi,
I have an old Nexus 7 (grouper on completely stock KTU84P, unrooted) that I gave up on a long time ago and recently found it again. I charged it up and the Google logo came up. And then the 'Start' in green with a arrow around it appeared. It was stuck. I could use the volume buttons to power off or enter recovery but that was it. Once in recovery, I tried wiping cache but that got stuck on 'Formatting /cache'.
Now, I do remember it got very sluggish when I last used it a long time ago to a point that it just used to freeze up on me every few minutes. Maybe, i hope not, but maybe it's got something to do with the notorious flash emmc(or whatever it was called) that this device has. If not, I'd love to be able to use it again in any way possible.
TIA.

It is possible. I tried sideloading a stock OTA package (using just adb) called '4939a9ff6d10c495beaed26ac96228246f724272 signed-nakasi-LRX21P-from-KTU84P 4939a9ff' but that failed. Then I tried the Nexus Root Toolkit's flash stock feature. It connects and goes well until it reboots to unlock the bootloader. The display doesn't turn on but the computer recognizes a new device called 'APX' with hardware id 'USB\VID_0955&PID_7330&REV_0103'. I've tried booting it into custom recovery using NRT but that didn't work either.
According to the current '3e' stock recovery I remembered that it used to run KTU84P (4.4 Kitkat) and never ran Lollipop which it seems caused some trouble too.
Please try Wugs Toolkit.
That is an easy program to do all kind of repairs.
It never failed me.

'Nexus Root Toolkit' or NRT IS Wugs toolkit.
Anyone?
I’m trying to re-root a friend’s Nexus 7 2012 'Grouper/Nakasi' that was previous unlocked and rooted years ago but now runs Lollipop 5.1.1 and is no longer rooted (but the bootloader is still unlocked).
I’ve tried the old methods I’m familiar with but these haven’t worked. Last night I tried using the Nexus Root Toolkit which ran without error (e.g. it installed SuperSU via fastboot) but upon reboot, the Nexus is still not rooted and now seems rather unstable.
The device does not have a custom recovery installed so I’d like to flash TWRP but I’m concerned this might either brick the device and/or wipe data. Once TWRP is installed, I’m hoping I can get the device rooted via a different method. NRT has an option to install a custom recovery but I’d rather install the latest version of TWRP from their website.
Any suggestions? My main concern is not wiping data!
Many thanks,
M.

TWRP doesn't brick devices. You can try using fastboot if you want to be 100% sure

Thanks, I realise TWRP shouldn't brick the device (I've installed it on many devices) but because this particular Nexus 7 is already not behaving nicely, I was concerned that it might take offence to TWRP! I'll try again tonight. Cheers, M.
TWRP and SuperSU flashed, rebooted and.... still no root access! SuperSU doesn't kick in when an app requests root access.
Any ideas?

Hmm.. Try another SuperSU zip file I guess.. Go with CM13 as the last resort
OK, this is strange, having left the device for over 4 hours SuperSU has suddenly started working! I wonder why it took it so long to start. This Nexus 7 is seriously messed up. Anyway, at least root access control is now working and I can get to work.

Is your device having some horrible lag every now and then? If so, try turning on "Show CPU Usage" in developer options and pay attention to how large the blue bar (kernel time) gets when you see mmcqd get near the top of the process list. I suspect that might be a sign of the eMMC chip getting ready for retirement.
I know that on my N7 (2012), this makes many trivial things take several times longer than they should.

Unless you have F2FS, it might be eMMC corruption or just technology acting funky lol I'd suggest install Trimmer since it makes the file system faster.
