Need help to unbrick my Nexus 7

Hi guys,
I need your help.
I rooted and unlocked my device using wug fresh toolkit 1.5.3.
After that I installed TWRP trough adb.
Next, I flashed Paranoid Android and everything was working fine.
By some stupid ideea that i had, because there was no space on my device
due to leftovers from the apps I had before, I tought I should go in TWRP and wipe everything,
than flash the Rom again.
I wiped cache, dalvik, restore factory settings and than I wiped sd card both internal and external.
Right now I cant flash the Rom again or restore a nandroid, because there is nothing on device.
Connecting to computer will not recognize it.
All I can do is, while conected to computer, use buttons and get into bootloader and from there on TWRP recovery.
Please help me with some instructions on how to make my Nexus 7 work again.
Thank you.

You can manually push ROM/Kernel/Gapps files to /sdcard using adb push from Android SDK.
I can't exactly recall if you can push the files from bootloader, or recovery, or both, but a push command would look like:
Code:
adb push FILE.zip /sdcard
adb push being the ADB command to push files from the computer to the device
FILE.zip being the name of the file you want to send to the device (for example, EOS-grouper-20120908-27.zip)
/sdcard being the place on the device you want the file to be placed in
In some cases, /sdcard may not work, but /data/media should work.
Another option is to restock using a factory image from Google and then start over with flashing CWM, and then copying over your ROM/Kernel/Gapps files.

I cannot push as it says "device not found".

Ok, I had to restock and unroot. Now is working fine. I used also wug fresh toolkit.
Will have to root again and so on...
Thanks!

When its finally booted back up, please remember

Also the bootloader keeps freezing on me after I attempt this.

I can fix this by turning it off and booting back into the bootloader and it will properly display my device ID.
It is unlocked and on 4.23 that's listed there. What else can I do?

engagedtosmile - You should post this question in comminus' stickied thread. I read all 54 pages of it and he's very good at diagnosing the problem and helping to get it resolved.

Hi, engagedtosmile...
Yeah.. there is a known issue with the v4.23 bootloader.
Your problem could be the bootloader v4.23 from build JWR66Y.... try flashing the bootloader v4.23 from build JWR66V.
See this thread for details (a couple of people have uploaded the bootloader v4.23 from build JWR66V, for both 'grouper' and 'tilapia' Nexus 7's on this thread - when I find the time, I'm going to upload them myself... so I don't have to keep hunting out the link).
Hope this helps.
Rgrds,
Ged.

Thanks but I have done that as instructed in the sticky post (I ran into the error before but was able to flash it fine). I thought I would try to Lock the bootloader and unlock it again, it locked fine but now errors out when unlocking.
I am back to step 1 it seems.:crying:

Have you tried changing to a different USB port on your PC... or a different USB cable, or even a different PC.
I know I've had difficulties, when trying to send/write to 'system', and changing to a different USB port usually resolves the problem... so it might be worth a shot.
Gotta be really careful when flashing bootloaders, as one false move can cause hardbrick, which is pretty grim.

[Q] writing 'bootloader'... FAILED (remote: (Unknown error code))

My N7 "2012" kept freezing, so I put it in bootloader and tried to do a recovery mode reset to stock. It froze during the process.
Now, the only thing I can do is get it into bootloader mode manually by holding the buttons. It frezes if I choose any of the options from the bootloader screen including restarting the bootloader from the bootloader screen without holding power and volume.
I have tried the Nexus Root Toolkit a bunch of times with the "flash stock + unroot (soft bricked)" feature, testing different factory builds and the best results are below:

PLEASE HELP! Keep in mind that I am a newb to messing with this stuff.
I have read forums and tried things that people suggested to others in similar situations, but I am pretty lost at this point. Keep in mind that my device is almost certainly wiped and definitely will not boot the OS.

Is your N7 the Wi-Fi or the 3G variant?
What was the name of the factory image you were trying to flash?

After doing a bit of research, I've found out that there is a BAD version of the N7 2012 bootloader 4.23 floating around. The unsettling thing is that it's being supplied with a couple of the factory images that come straight from from the Google android devolpers page online. Anyway to make a long story short, I would try flashing the working version of the bootloader first off, then go from there with a factory reset. You can download the the working bootloader (bootloader-grouper-4.23.img) HERE --> h t t p : / / g o o . g l / q A D S A z (sorry about the spaces in the url, I'm new to the forum and can't post links yet, just delete the spaces)
BTW, its the same bootloader for N7 wifi OR 3G. md5 = df53028033c9eccf4fe5ba7bc198ce24
Here's how to install using fastboot:
1. Reboot To Your Bootloader On You Nexus 7 (Power off power button and volume down until you see bootloader screen)
2. Connect Your Nexus 7 To Your Computer
3. Open Up Command Prompt or terminal window (not sure if you are using windows/mac/linux)
4. CD to where you downloaded bootloader-grouper-4.23.img
5. Then type:
fastboot devices (to see if your N7 is connected correctly)
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
Then try the factory reset again.
If you don't have fastboot installed your computer you need it. Makes flashing your N7 a breeze... lock/unlock, custom recovery installs, going back to factory stock, all much more easy with fastboot.
You can get it from the android devolper site, h t t p : / / g o o . g l / 2 q p r for windows/mac/linux. All you need is the SDK tools, not the ADT bundle.

I read that guide.
But that guide seems to be written with the assumption that the device can boot into the OS
No ADB device is found because I can only boot into bootloader.

That part is only for the driver installation. You can skip to the "Extract the Factory Image" part and follow it from there.

The Nexus was frozen at this point and had to be manually forced to restart bootloader.

Do you have a valid warranty for the N7? I'm asking because it seems that your N7's internal memory got corrupted. I might not be right, but that's my best guess.

Thanks for your help
I bought it 13 months ago (perfect timing, coincidentally, right?), so if I could find the receipt I would still be screwed.

I would still try to send it to Asus or Google. Maybe they repair it for a reasonable price.
(But if you plan to do that try to relock you bootloader with fastboot oem lock)

Gave my 2012 N7 to my nephew, a month later it's frozen 'Google' in the center and a green arrow / start up top. Using the vol. keys I can cycle between start/reboot bootloader/recovery mode/power off, selecting anything but power off loops.
Also, I had to reinstall the sdk but 'adb devices' shows nothing. Any hope of bringing this back to life?

If you are in fastboot, adb commands will not work, you need to use "fastboot devices" to see if you are connected. If you are flash a recovery from fastboot and you can work fairly easily from there. Is the bootloader locked or unlocked?

Hi, joe2262...
'adb devices' will not show anything if the device is booted into fastboot mode.
The command you need is 'fastboot devices'...
This will confirm you have a working FASTBOOT connection... and from which you can run fastboot commands... such as fastboot flashing a Custom Recovery (CWM or TWRP).
Or alternatively, fastboot flashing back to factory stock.
Either way... I suspect your Nexus 7 is likely recoverable.
At worst, it's just 'softbricked'.
Rgrds,
Ged.

Yes, it's unlocked but I want to go to a stock install.

Nakasi - dead for good ?

Hello people,
I think, I've killed my nexus7 nakasi - 16GB model for ever today. Could you please help me try to resurrect it, or did I really kill him ?
Before, I was using unlocked, SuperSU rooted, KK 4.4.4 with TWRP bootloader and disabled some services (to stop stupid ota notifications coming up).
Today I wanted to try 5.1.1 (LMY47V), so I downloaded the ota, unzipped it, loaded adb, reboot into bootloader and ran flash-all.bat, as usually (I have already done it coulpe times before and never had any problems), until now.
Everything was running fine, until rebooting into bootloader ... ok.. waiting for device. The command line has stuck, so I removed table, terminated job, and tried booting bootloader by volume- & power. Nothing.
Please find my log output below.
Code:
D:\temp\adb>adb reboot bootloader
D:\temp\adb>flash-all.bat
...

^CTerminate batch job (Y/N)? y
Is there anything I can do to revive him ? Or is he dead now ?
I have tried:
VOL+ VOL- POWER
VOL- POWER
Disconnecting battery + combination of previous before & after battery removal
Connecting power + combination of previous before & after battery removal
When i connect it to my pc now, I can hear sound of new device connected - in APX mode.
Holding POWR VOL+ VOL- for 15 sec, causes tablet to disconnect and connect again in APX, but bootloader won't start.
Plugging it on charger does nothing, battery indicator doesn't show up.
Please help !

Hi, remusator...
Sorry to be the bearer of bad news, but it sounds like your Nexus 7 is hardbricked. Both APX mode and the lack of the battery charging animation are classic hallmarks of a bootloader that may have have become corrupted, erased or accidentally overwritten.
APX mode is the state the N7 defaults to in the absence of a working bootloader, and with the expectation that somebody with the necessary software tools and knowledge will be able to nvFlash a replacement bootloader.
Unfortunately, there is no universal nvFlash tool available for the Nexus 7. The only way of accessing nvFlash on the Nexus 7 is, if you had, at some previous point, created your own unique Nexus 7 device dependant 'wheelie' blobs via the Flatline procedure.
So, without a working bootloader, the Nexus 7 cannot boot, nor can it be reflashed via fastboot commands (since it's the bootloader that 'accepts' those commands).
The only option (other than via nvFlash with previously generated Flatline 'wheelie' blobs, and which I suspect you don't have) is to have the motherboard replaced.
I have read accounts here on XDA of people sourcing Nexus 7 replacement motherboards from various online sources, and performing the replacement themselves. I don't know how easy or difficult it is, or how much it might cost (probably not much), but with a dead bootloader, it's likely the only way of resurrecting your Nexus 7.
Good luck...
Rgrds,
Ged.
Addendum: I assume you've tried all of these (that might be applicable)...
