[SOLVED] Unbrick Nexus 7? - Nexus 7 Q&A, Help & Troubleshooting

Hey everybody,
Yesterday I tried flashing a theme to SmoothRom and got caught in a bootloop. In a panic, I accidentally factory wiped my sd card and lost my roms so now I can't flash another rom to my Nexus 7. I've tried adb pushing a rom to the sd card, but my Nexus 7 is not being recognized in adb devices. I've tried everything to my knowledge but I still cannot get anything to work, even tried working on Mac and PC computers and my Nexus won't show up in adb.
I'm ready to count my losses as it is my fault, but I figured you guys could help out. I love my Nexus so if you guys know anything I could do I'd greatly appreciate it. Thanks.

Do you still have access to recovery? What about fastboot? What version of android were you on?

Yeah I can still get into fastboot & recovery (Clockwork mod touch). I've tried mounting the sd card in recovery but nothing happens. Tried doing adb to sideload a rom but my device is showing up.

https://developers.google.com/android/nexus/images flash the one for your device (You will need to use fastboot)

Re: Unbrick Nexus 7?
You can go two ways here, either you can do as the above user posted and flash a stock image via fastboot or if you have a otg cable and a pendrive/removable media you can use that to install the rom

Ok guys, I spent all last night trying to get this to work, and I'm still having problems. I tried adding the line to the driver inf file but nothing worked. I tried adding the PDANet drivers, but the Nexus of course is not showing up. I know that my Nexus is not doomed it's just something I'm not doing right, not gonna give up I'll keep at it. Thanks for the help guys, if anything have any suggestions let me know!

Sounds like you should find out if CWM touch can mount a USB flash thumbdrive via an OTG cable. You can avoid driver problems that way (as long as it works). The filesystem formatting of the USB drive with the highest probability of success will be a FAT format.
good luck

hello!sorry for hearing about your tablet!mine today fell of a chair and the glass is broken so if you try everything and you can't fix your tablet i would like to buy it for the screen cause it costs a lot for a replacement!!!thanks!

There's nothing wrong with it... you just need to flash stock with fastboot or adb sideload it.

Wipe data again, wipe cache, wipe dalvik cache, and re-flash SmoothROM.
Good luck, a bootloop is not a simple thing...

Somehow I have screwed my nexus 7(16gb wifi only) up so bad that I cannot get back into fastboot or recovery mode. Any attempt at bootup is met with a blank screen. How do you suggest I proceed?

If fastboot is really dead, then you're out of luck. Have you tried running fastboot commands, however, after trying to boot into fastboot? Sometimes the underlying software will run correctly, even if the screen is nonresponsive.

So I assume this means my only hope is to replace the motherboard which houses the memory. Is that a good assumption?

HELP!
so i had the same thing happen to me. I had access to recovery still but instead of re flashing i tried to use nexus root toolkit to factory reset. somehow fastboot failed halfway through and now recovery is gone with everything else. The only thing i can get into is the bootloader mode....
My device is still listed as a fastboot device, but when i try to re-run the flash to stock i get this: (see attached picture)
Please help, I honestly have been working on this for days, but i simply do not know enough to fix it!
I will post a new topic if no one responds. Thanks

I'm having a similar problem. Present state of the device is that my N7 boots into the bootloader and then to the custom recovery. I've accidently erased the OS.
Can you tell me how you managed to unbrick via OTG. Should I move the factory image to usb flash drive and then mount it via OTG and then try to flash it via recovery???
Please help:crying:

Travisdroidx2 is right. You simply need to connect your N7 to a computer's USB port and then you can access recovery mode via the steps you mentioned or via adb. It's a bug that Google is going to fix eventually (I hope).

Won't mount

Edit: Didn't mean to post this but since it's here... Anybody have a quick fix for no OS install but won't mount to push new file to tab?
Told you not to use the toolkit.

Try disabling Android Debugging or mount USB in custom recovery.
Or since you just want to transfer a file from PC to N7 try AirDroid.

HELP: I screwed up my Nexus 4 after fully formatting it.

I feel kind of sick...
I hope someone can assist. I screwed up, big time.
I decided to full wipe my device and choose to flash stock using Toolkit. However, usb debugging isn't shown as being enabled (I think) and I'm unable to get back into a ROM to enable it, since fully wiping my entire storage.
I have tried reinstalling drivers on so many occasions, I've tried pushing files, using sideload. Nothing works. I literally cannot find a way to flash any rom onto the device. I have CWM recovery, but no way of getting zips onto the device. I cannot access usb debugging. Toolkit always reads the serial for fastboot but never shows any active devices for ADB.
I'm stumped and currently have no way of using my device.
I should've never tried to wipe it to begin with.
Thanks to anyone who might be able to assist. I'm sorry to burden you all.
if you can access via fastboot just flash your system.img to the phone with fastboot flash system system.img!
too bad google pulled the nexus 4 factory image
I have the factory image for the Nexus 4. Send me a PM with your email address and I'll send you the link to it on my Drive.
Use the nexus 4 toolkit to download the stock image for the phone and use keys on phone to boot to fastboot. Then connect phone to your PC and run the nexus 4 toolkit. It should detect your phone in fast boot mode and allow you to flash stock rom

Do you want to flash the image now? [type yes or no]:
It doesn't actually download, despite attempting to. I'm not sure why.
Google pulled the files on Dec 12 hence no download. What toolkit are you using? The one from WugFresh has a link to the images on goo.im.

Many thanks man. The factory image worked like a charm. I didn't even have to extract it. I just flashed in via toolkit. I dropped the file into the put_google_factory_image_here folder and then flashed it using option 9. I'm so relieved to have a working device again.
Thanks to all that attempted to help my situation. I appreciate every effort made. Thanks for being so very patient.
Please feel free to use the thread to discuss similar matters further. I'm sure many in the future will find it very informative to refer to. It saved me and my N4 from a lifetime of despair! :good:

Nexus 7 stuck on GOOGLE booting screen

Hey so yesterday I mucked around with the mounting/unmounting/formatting stuff in fastboot. Now it's not booting up, it's stuck at the GOOGLE logo. I left it on overnight, and it's still stuck there. I can still turn off the device and enter fastboot mode. Anyone know what's wrong?
Thanks
How do you want to know what's happening to your device if don't tell us which commands you have done exactly with fastboot and why ?

Sorry
I went to the fastboot menu and unmounted everything, and formatted everything. Then I deleted all user data and the cache partition. I'm running xenon HD rom.
Thanks
You were running xenon rom before you formatted everything! Now if you want to stay with xenon you have to push the rom in your device using adb and install it with recovery.

I would say to get Wug's tool kit and use that to unbrick/flash back to stock. To get your computer to recognize the tablet you likely need to install the proper drivers, which are included with the toolkit and instructions on installing them.

The problem is, I don't have USB debugging on, so it's impossible to install the drivers.
Go in bootloader/fastboot mode and then type "fastboot devices" to see if your device is recognized

Did you reflash the ROM and gapps after doing the wipes? Otherwise, try: factory reset, format system, flash ROM, flash gapps, reboot.

Accidentally deleted OS, stuck in TWRP recovery

Well, it looks like I unintentionally wiped the /data partition using TWRP right after I did my first backup after rooting. Now I obviously can't boot since system, data, cache, etc. are wiped. The backup I just made was also wiped

Wiping data partition does not wipe the rom. It just resets your rom back to a freash install.

Not sure about twrp. I use cwm and able to load roms through recovery from PC. You should be able to do it with Twrp. If not you will have to kdz back to stock.

Is there anyway to mount your phone to your computer? As there is the button on the main page of twrp 3rd one down. If not you should be able to use the adb push command to push it onto the "memory" of the phone allowing for you to read it and you to flash it from there. Or that's happened to me.

I managed to do this once, I used TWRP adb sideload to push CM11 to my device then flashed back to stock from there.
if u have twrp 2.6.3.3 it will support otg u have to mount it after you connect to phone in recovery mode if not try format the card u r using for otg with fat32 file system and then try and if it still does not use and sideload in advanced settings to push rom, unfortunately LG drivers in pc does not seem to help pc see your phone in sideload mode so try installing pdanet drivers in ur pc and then connect ur phone to pc in sideload and push rom I did this several times and it worked all the time.
