For Those Who Semi-Bricked Their Nexus 7 0MB Interal Storage

Hopefully this helps people in my situation.
So on the first day of having my nexus 7 i found a way to have no OS and 0MB internal storage showing in TWRP. Yah i suck.
I tried tons of things but knew a system image was needed.
HOW: I was about to flash the superuser root for 4.3 newly released and forgot to put it on nexus so i then proceeded to exit TWRP, however upon exiting TWRP the recovery detected i havent installed supersu and asked do i want to install superuser? I though why the hell not!
I confirmed to install superuser and then tried to reboot but for 20 minutes device could not boot. TWRP showed 0MB internal storage and pushing adb files in this state yielded nothing as there was no directory
This is how i managed to have a working tablet again
1. FORMAT DATA in TWRP - after doing this your internal storage should be back and not show 0MB
2. reboot to the bootloader
3. On your computer download this file kindly given to us by phuduong and uploaded by Nburnes

4. Once downloaded move that system.img file to your adb directory
5. With you nexus 7 in the bootloader, adb open, and file downloaded copy and paste this command into adb terminal
fastboot flash system system.img
6. Now you have an OS but it still would loop and wouldnt start
7. Boot into recovery and Format Data again, because for me 0MB interal storage was back again
8. Then Factory Reset
FINALLY YOUR DEVICE SHOULD BE BACK TO ITS ORIGINAL STATE!!!!!

Is that the factory image? Have you tried going from unlocked bootloader & rooted back to factory using that image?

Google has yet to release the official factory image for the new N7. However, a kind user was gracious enough to make their own. It is likely to be almost identical to what Google will eventually release and should work the same way.

Thank you! Thank you!

good stuff OP. glad you got it working again

You all are life savers! 1000X Thanks!

I tried running through this, but it didn't work for me. I think my situation is different though because I tried to install a factory image for the 2012 nexus, and during part of that process I ran the "flash-all" script which starts by deleting boot, cache, recovery, userdata, and system.
I think deleting boot screwed me up, because even though I can go into recovery now after reinstalling twrp and I can restore my system using system.img, I still can't boot (get stuck on the google logo). Any way to fix that?

So you first tried to restore from the OLD Nexus 7 Image?????

Yes, I tried to restore from the old image. Obviously fastboot wont let you install the old image, but I didn't realize that until boot, system, cache, etc. were deleted

THANK YOU!!!
This worked perfectly! I had a wiped system folder (no ROM), and obviously no USB debugging enabled. And with the lack of a factory image, I've been counting seconds to seeing somebody post this!
Just follow the instructions carefully. Thank you guys!

You can flash old and new image through fastboot. I did 2 times ^_^

OP and nburnes saved my butt!

I did this and now it seems my device is booting and it shows up as N7 when I attach it to my PC. But the display shows nothing at all. It just goes blank after the Google screen. Any ideas?
After flashing everything I could think of and banging my head and the device against the wall for two hours, I finally got it to work. Not sure how exactly but the last thing I did was reflashing bootloader. So if anyone has the same problem, try that.

Thank you.
Note:
Give step 6 a little time be patient.

[Q] Need some help please

I have a Nexus 7 wifi, It is stuck at the Google screen boot looping. It is unlocked and has TWRP 2.5 which I can access. I have tried every tool kit to no avail. Need some help please!

dont use a toolkit
get to a command line and figure out whats wrong by trying to flash a factory image, or run factory reset in recovery and see if it fixes it.

I tried factory reset but it fails. I tried to flash a factory image through side load but it fails.
If I go to advanced wipe and do them one at a time they all work except data.
It appears to have nothing on intrenal or external storage.
One other thing is when I try to mount the system in twrp it asks for a password?
I have never setup a password so I don't understand this.
Thanks

Did you encrypt your device?

No, not at all that's what's so strange.
I purchased it new and it started locking up and after an attempted factory reset here we are.

Factory reset would wipe data partition leaving nothing in data. Makes sense that it wouldnt let you wipe that when there is nothing there.
Try flashing a factory image from fast boot. Not from recovery.
Sent from my Galaxy Nexus

Would it not have to be loaded on the device? I tried it with a tool kit and it gets to the end and fails on verification.
I don't remember what version it was so that doesn't help. I think it was 4.1.2
But not positive.

Okay seems to be a problem with twrp 2.5 as far as the password I'm downloading 2.6 now.

Use fastboot to flash new recovery and system partition. You run fastboot commands from your computer not from recovery and your device needs to be in bootloader not recovery. It does not require you to load it onto the device prior

[Q] Encrypted n4 stuck on nexus X logo after flashing twrp

So this is going to be a step by step of my problem. 1 I unlocked my bootloader manually without using a tool kit. 2 I proceeded to flash custom recovery twrp 2.6.3.0. 3. From the bootloader screen I select recovery and and when twrp open it immediately asks for a password that I have no clue what it is, so I click cancel.4 I go to do a factory reset within twrp and It fails, so then I go back to the main screen of twrp and select mount and I notice that the system and data options are unchecked so I check them and then there is the option to decrypt data so I select that and again I need to input a password to continue. 5 after all this fustration I then open nexus root toolkit by wug and click the option to flash stock + unroot (current status:soft bricked/bootloop). So the toolkit does what it needs to but after all that my n4 still does not boot pass the colorful X logo. So this is my issue hope I can get some help

Try going into the stock recovery and doing a factory reset from there.

[Q] Nexus 4: Can't wipe/Flash factory image. Semi-bricked phone.

Earlier today my phone was working fine running Stock 4.4.1/Kernel. I decided I wanted to get the franco kernel so I got the .img file from the xda thread. I flashed the .img file onto the boot partition using fastboot, and restarted my phone. After a few minutes of sitting at the "Google" screen I rebooted into the bootloader. I tried flashing the 4.4 factory image using the "flash-all.bat" without wiping anything. My phone continued to get stuck at the "Google" screen after multiple reboots. I then tried to wipe my device using fastboot. However, when using the command "fastboot erase system" I got an error that said "Failed: unknown chunk type." I kept on retrying the wipe to no avail. I found this thread: http://forum.xda-developers.com/showthread.php?t=2347060 and followed the steps. All the steps seemed to work up until I had to flash the given factory image using fastboot. I got the same "Unknown chunk type" when the cmd was trying to write files to the "system partition." Before you ask, yes my fastboot/adb is updated to the newest version. (I triple checked) And all my drivers work properly. I just flashed the 4.4.1 firmware 3 days ago using fastboot and everything went perfectly, including the wipe. Please offer any solutions you think could get me out of this situation. Thank you.

Never encountered something like this, but maybe from bootloader u can get into ur stock recovery & wipe cahce & wipe data.
once again I never had that issue...so its upto u...but might be worth a try...if u had made a backup or dont care about the data in ur phone then it did be easier for u u to try

Flash the factory images and erase all partitions on the device. If you want to get some data from the internal memory you could pull it through recovery. Next time read more do less. Franko's kernel uses different ram disk than the stock one. You could also try to flash a full stock kernel for your build first. Get it from the factory images and flash it through fastboot.

What's the exact same problem? Did you flash Franko kernel too. If so just dirty flash your current rom.

Can you get into bootloader mode. It's worth a try. Your not bricked if it can turn on. Your emmc may be bad and flashing the factory image won't work. But if that's the case then warranty or replacement are your only options.

Use nexus root toolkit to temporarily boot into recovery and wipe everything, then flash a ROM, or download a factory image from Google and run the flash-all.bat

After flashing it, did you go into the stock recovery to factory wipe data before booting it up? You have to do this or else you will get stuck at the Nexus bootup screen. Happened to me once. Apparently you have to do this on the Nexus 5 and Nexus 7 because flashing it doesn't properly wipe the partition.

Hloo m.charesa,of course I wipe data,partition after flashing many times(I watched the clip in youtube does that),But unfortunately due to the nexus logo.

It seems that the problem is not to activate the USB debugging , because after opening bootloader or installing stock rom returns the device to its origin and must be activate (usb debugging) again .. Question: Is there a way to activate it without the operation the system (because its not operation originally)??​

USB Debugging is only necessary if you are trying to use ADB when the phone is on and booted into the OS already. It's not necessary when you are in Fastboot mode (at the bootloader). Not sure why it's not working flashing the factory image. This is why I prefer not to use toolkits and do everything manually. That way, you know where things went wrong.
