[Q] Restoring Stock Android on Nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

Hi I have a problem with my Nexus 7 (32 gb wifi only version).
My son in his infinite wisdom decided to install ubuntu on the tablet.
I went to try and restore this back to the android version but all it did was to wipe off ubuntu itself
I then went on jayceooi.com and used the nexus toolbox to see if I could reflash the images etc.Howveer although all the files were downloaded I canot get the laptop to recognise the nexus itself (even though it sems to charge the tablet). There is no menu at all to check whether or not usb debugging is ticked or not..
Im now left with the tablet without no apparent operating system. At the moment all it shows is the green android with fastboot mode but when I hit start it says booting failed.
Could someone help please before I do any more damage and I brick it completly (although I may have already done so)
thankyou for any help

thanks it mentions it being a root toolkit. I didnt actually want to root so is it still ok to use to restore back to stock android?

It can do more then just root

Yes it can do restore back to stock. Just follow the guide to unlock bootloader so it can flash stock image then just re lock bootloader. It covers the process in op.

Ok thanks all. Seemed to be doing everything ok but its been stuck on"waiting for your device to finish booting back up" for about 30 minutes now. It did say it would take 5 to 10 mins but should i carry on waiting or abort and start again do you think?
thanks

I would reset it see if that helped

If your son re did the partitions for Ubuntu that could have messed things up pretty good. I have only had my nexus for a few days so I couldn't tell you how to fix the formatting quite yet. I would search around on how to verify and correct the partitions if needed.

Just use recovery to restore your backup.

This is about the 15th post I've seen this week about someone screwing up their n7. If there already isn't one there needs to be a step by step video for the correct way to unlock, root, and flash Roms. I suggest others read heavily before doing any flashing. Its bad enough the boot loader is already screwy.
The toolkit does everything for you. All in one method and you're done.
I'm sure its his .img

I had this problem happen with my Xoom.
Boot into the bootloader from recovery. There should be an option to do so.
In the bootloader flash a different recovery.
Then reinstall your ROM. It should boot.
If that doesn't work I would suggest flashing the stock images in fastboot and starting over.

I had a similar problem on my og evo. Try seeing if you can flash the recovery from a computer while booted into cwm. Then it'll reboot into new recovery, you flash rom, and you stop sharding your pants

Even choosing "reboot bootloader" in recovery?
If that doesn't work, connect to you your computer and using adb type the command
Code:
adb reboot bootloader

I dont have a reboot bootloader option but when i go to reboot system it goes straight into cwm like i said.
Also fastboot/adb is not working. When i run a command it says "waiting for device" on my computer
Sent from my myTouch 4G Slide using Tapatalk 2
On a side note, i had tryed everything i formated the sd in cwm and now it appears on cwm as if theres "No files found" but on my computer everything i had previously is still there.
So there is a connection to the storage part of the device but not adb or fastboot

Hmmm. You should have a working adb while booted into a custom recovery. Are your drivers installed correctly?
Also, the reason why you computer sees the files is because with mtp it caches the files.

Now im able to boot into the bootloader so i can run fastboot commands. I currently have NO rom whatsoever installed so im waiting to flash the stock rom using the toolkit. Thank you for your help
Also when i booted into twrp it said i had 3% battery left lol so im just hoping it will work now.

OP will stop making threads like this if people stop recommending toolkits......................
And definition of brick is beyond repair - unable to boot up, e.g. Black screen when power button is pressed, not even the Google screen.
Will the next nexus have a longer screen?

Well it was beyond repair for the moment being if i did NOT have access to adb, fastboot, nor the Bootloader i said that three times already.
But whatever i finally got adb to work and was able to fastboot flash a stock image. Thank you so much el daddy for your help i really appreciate it.

Sorry I wasn't trying to bust your stones. I haven't rooted yet because of all of the posts like yours. I've just seen more problems with flashing on this device then any other that I have with my past Droid devices. What we really need is apx (spelling?) Drivers and n7 files for a sure fire recovery from any disaster
Hopefully I don't have to start another thread.
I too think I bricked my Nexus 7.
I was having trouble and I accidentally cleared a file from the System UI app (its a system required app) which caused me to loose the 3 buttons on the bitten of the screen.
So I went to CWM to do a restore which said it failed.
After that it would not boot.
Its just stuck with the Google logo on the screen.
I held down the power up & down volume buttons and I get a screen that gives me that START button on the top right of the screen with the text in small size on the bottom left.
I can use the up and down volume to make the start button change to recovery mode or bootloader but activating them just goes to Google logo.
Can I recover or is it totally lost?
I also don't remember if I left the Nexus 7 in Debug mode which is usually required to perform custom Roms
Thanks

How to manually push factory image to nexus 7? Help.

So here is my dilemma. I was having problems with my Google apps for whatever reason. Manually updated to 4.2 and still has the same problems. Did a factory reset and the problems went away. Decided I wanted to get rid of root and relock the bootloader since I'm going to give her thus one because I'm upgrading to the 32GB model. Wanted to get rid of the superuser icon in the app drawer mainly. I went to googles site and downloaded the factory images for 4.2. Used it in conjunction with the nexus 7 toolkit. Long story short for whatever reason the process didn't complete. Pretty sure I don't have a factory image at all at this point. I tried to use the nexus 7 toolkit but of course now it won't see my device. My tablet is still unlocked. I'm assuming I'm going to have to manually push the image to the phone. If any body can start me off in the right direction it will be greatly appreciated. Especially if someone were able to provide links to the info I may need. In the mean time I'm looking around on Google. Haven't found anything concrete yet. As a side note if anyone could tell me how to actually turn off the tablet do I can preserve the battery it would be appreciated. I can only get it to show fast boot mode or the Google screen. Can't power down.

Dunno... after trying to update yesterday, twrp, cwm, stock wasn't having it, had to put stock boot loader back on, everything wiped, not a problem....nandroid backup....toolkit shows it working but nothing, toolkit said everything was there....only unlock and root worked, everything else was borked.
And I had to use Windows for the tool kit. Doh.
Toolkit has been a bane for me, finally got 4.2 using root keeper.
Off-topic.... maybe.
Lesson learnt... definitely.

[Q] Making Nexus 7 Stock Without USB

Well, after trying to charge my Nexus in the car, it appears the USB has gone kaput and only charges the device now (although it doesn't actually say it's charging, the percentage just increases). Anyway, as it would appear a return is in order, I'd like to remove the unlocked sign on my bootloader to be able to send it back, but without USB, the conventional fastboot/adb method is out the window. Anybody got any suggestions? Thanks.
Bump, per chance?
Use wugfresh toolkit and Hitt the oem lock option
Sent from my Nexus 7 using xda app-developers app
The OP clearly said they are looking for a method that doesn't require USB. So your method suggesting he use wugs toolkit isn't the answer he's looking for. And honestly I don't think there is a way to do it without USB capabilities.
Sent from my Nexus 7 using Tapatalk 2
I don't think you can.
I'm not exactly a pro at this, but as far as I know you need fast boot mode to lock/unlock the bootloader.
I installed twrp last night (got bored with cwm) and noticed it has a command line section. I don't know if you could use this to lock the bootloader. If you look up one of the manual guides to locking/unlocking maybe try whatever it says to type in a terminal there?
The only problem is then you couldn't put back the stock recovery.
Sent from my Nexus 7 using xda app-developers app
You can use this to install the stock ROM and kernel, there is also an option to unroot it. http://forum.xda-developers.com/showthread.php?t=1929270 (install zip in custom recovery)
I don't know how to OEM lock your tablet without a pc..
Hope this helps

I would be really surprised if it is not simply a bad micro USB cable. Try another one, if you have it laying around, or pick one up for cheap. My unofficial cable would charge, but not write for some reason.
i had the same problem after using a car charger.After some days that i charged with original charger only, charging icon started working and also fastboot.But usb otg functions were still dead either in twrp recovery or inside the rom.
After i flashed ota update (i was in stock 4.1.2) for 4.2 it magically started fully working.First i thought that it was 4.2 that made it work,but i went back in 4.1.2 (nandroid restore) and it continue to work ok.Of course i dont use anymore 3rd party chargers.I see now that my bootloader is 4.13 but it work ok with 4.1.2 too,so i will not change it to 3.41
I've tried 4 or 5 different cables and no luck unfortunately. Going from my beloved PA 2.54 to stock 4.2 temporarily to see if it fixes it, fingers crossed!
Update: Unfortunately I've not been so lucky problem persists...

Adb won't do it, it has to be fast boot, and it has to be usb.

revert back to android

hey guys i did a native install of ubuntu on my nexus 7 without multirom and now want to ditch it for android again. i see that it didn't get rid of twrp and i can still get into it so if i just did a full wipe including data and then flashed a rom would i be good to go or is there a certain precedure i should be following?
I would try flashing an official CM10 Rom as they typically have better flashing procedures to make sure the partitions are setup right and stuff.
I'd think you'd be OK though.

Id use WugFresh's Nexus Root Toolkit to reflash stock. It walks you through it, and that way it will make sure the file system is set up correctly. Then just root again.

Grouper bricked after latest 4.3 OTA, no recovery

Heya...
On my 16GB Grouper I had installed the stock rooted 4.3 rom. Yesterday a system OTA update message appeared on my screen - 1.7 MB. I let it download and install over night and just went to bed. Came back in the morning to a boot loop where the device got stuck with the four colorful thingies animation. I can access the bootloader, but the recovery seems to be broken. Can't remember if I had anything other than the stock one... Anyways, now I'm strugling to get this thing going again. I am a zero at ADB but willing to learn whatever is necessary to get me started with a working recovery at least. No tool root box will do anything really for me...
Thanks for your help in advance
Hey!
Had a problem just like yours. If your running windows then install this program its called nexus tool kit. I'm a newbie here but if you Google 'nexus toolkit wug fresh' you can find it
All you need to do is plug your device in and open the program, then select flash OTA with the boot loop option and then follow the on screen instructions
That should put you back to normal with a fresh start meaning all you data will be lost. You can also root from there to.

Yeah. It would be dumb to actually learn what you are doing to your device. You should totally use a toolkit.

Thank you guys. You might not believe it, but I'm not a newb to Android or flashing. It's just that I've always been playing around with Samsung devices and there you'd normaly turn to Odin in case something went wrong. Here it's different.
Anyways, with this comprehensive guide I've been able to reflash a recovery image and my old rom. Unfortunately losing all of my data in the process, but there was no way to save it.
