[help] i bricked my nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

Hey , everything was fine but i opened cwm recovery and formated everything by mistake including /sdcard/system .... my nexus is now struck at google logo and dsnt do anything , but i can go to bootloader and also clockwork mod recovery. i dont have drivers in my pc and debugging is not enabled in my nexus , so i cannot flash stock using NRT. how can i unbrick my device.thanks !

Debugging makes no difference, since you formatted the system. You need to flash stock using fastboot from your pc.
Download 4.2.2 image from google to pc. Download fastboot via android sdk to pc. Boot into bootloader. Fastboot flash android to N7. There are instructions in the stickies. Also, does cwm allow usb mounting? If so, you could put a custom rom and gapps on a usb stick, mount in cwm and flash rom there. Otg needed for the second option.

If CWM allows you to mount something using OTG, put a ROM on a (FAT-formatted) USB key drive and mount it using an OTG cable. And then flash that ROM.
TWRP will let you do this; I'm not sure about CWM.

If you are able to get into cwm,you could simply sideload a rom/kernel... All you need is adb (part of the android sdk) and the Google usb driver.

[Q] help, no rom in my nexus 7

I Did something really stupid, I have a Nexus 7, rooted, unlocked, went to twrp and did a back up of the stock rom, it said successful, then rebooted used the rom, everything perfect but I had tablet mod on it, decided to go back to full stock, booted to recovery, wiped everything, tried to restore and my backup is not there, and I deleted the rom as well, so now I have no rom to flash and I'm stock in recovery, anyway to push a rom into the nexus in recovery or bootloader? I tried flashing it with root toolkit 1.5.5 but it doesn't find the tablet,(all the drivers are installed), any and all help is appreciated...
Your PC won't see your N7 in Android because you haven't turned on USB debugging, and probably can't now.
You should be able to push an updated TWRP in fastboot that will see your 4.2 backup. The older version can't find its backups in 4.2,as you've discovered.
I'm not the lowest of the low, but I am the slowest of the slow.
I did have it on, I can see the tablet from control panel, but when I run the kit it says adb device not found..

The drivers will let your PC see the N7, but you have to be in USB debugging for ADB to work. You lost it when you wiped your system, as the failure of the toolkit to see the ADB proves.

USB Debugging doesn't need to be on for ADB through recovery to work.. Why would it? The system isn't even on it is in recovery.
Try the toolkit in fastboot.

when I'm in the bootloader it says it's in fastboot mode, but the toolkit wont find it!
I running recovery 2.3.2.1
tried adb sideload as well and it says "cannot read sideload" any ideas? getting a little crazy here..
Can anybody give me specific commands in ADB or fast boot I'm an idiot when it comes to that, on how to try to push a ROM into the device so I can flash it from recovery, or maybe a link to where I can read about it, I would really appreciate it..

While in recovery, type in the following:
Code:
adb push <name of ROM zip> /sdcard
You need to open a command prompt window, change directories (cd) to your Android SDK - platform tools directory, and to make things easy, move the ROM zip file into that directory as well (platform-tools that is). Then type the adb push command above.
EDIT: This puts the ROM zip on the root of your sd card (/sdcard). I have a ROM folder on my sd card, so I would type:
Code:
adb push <name of ROM zip> /sdcard/ROM
This just shows that you can push a file into a folder on your sd card.

nexus 7 without ROM - cannot mount USB

Guys..
I desperately need your support to turn my nexus back on .....
I used JROMFlasher tool and it erased all the data from my SD card.:crying:
I am stuck at google logo now..
I can boot to recovery.. But there is no ROM in my SD card.
I cannot mount USB from recovery..
I am on windows 8 and ADB is not working in my PC.
Is there any way to put ROM in to my nexus and make it work

Fix your ADB before doing anything else
This is fairly easy to recover so you don't have to panic. You need to get ADB working first, or revert back to Windows 7.
Then install or boot directly into TWRP recovery using: fastboot boot twrp.img.
While in TWRP, choose the "ADB sideload" option. Then load and install the rom by typing: adb sideload rom.zip
Or you can also follow the instruction to factory reset your device: http://forum.xda-developers.com/showthread.php?t=1907796
Also Nexus devices can't mount USB storage while in recovery (as far as I know).
You can mount external usb storage via usb otg if you use twrp recovery.
If not, or you are on stock recovery, adb and fastboot will be necessary.
I got adb and fastboot to work on windows 8 64bit by strictly following the guide from wug's toolkit. Support for linux is better. The nexus 7 is recognized automatically by arch linux (just install android-tools from aur for adb and fastboot). Maybe ubuntu linux works just as easy to recover your nexus, which you can try through wubi.
Once I was at the same I was in Win8 too..
I don't remember exactly how but I was able to install ADB only using fast boot with the help of WugFress Nexus Root toolkit.... And successfully booted into the system....
You can also boot into temporary custom recovery using this toolkit....
You can get the toolkit from the link bellow....

In cwm there should be an option to mount the device as usb storage. Try that. It should let you plug the phone into the pc and simply copy the zip onto the phones internal sd.
If thats not working try this to set up the drivers. Then plug the phone in and boot into the bootloader/fastboot mode. The open command prompt and cd to the android-sdk/platform-tools directory. Then run the following command:
Code:
adb push /path/to/rom/on/pc/ /mnt/sdcard/
still not working
Still not connected to windows, I cannot do any thing with my device
Download any ROM and do the following:
1. Connect phone to PC when in fastboot
2. Install drivers (if required)
3. Flash latest version of CWM using fastboot flash recovery name_of_recovery.img
4. Reboot phone into fastboot using fastboot reboot-bootloader
5. Boot into CWM
6. Install drivers (if required)
7. Select 'Install via sideload'
8. Flash ROM using adb sideload name_of_rom.zip
9. Follow instructions in CWM
If that still doesn't work, go back to stock using this guide (and read ALL of it):

Thank you for your quick replay
My problem now that I cannot connect my device to PC, I installed drivers every thing and when I open fast boot or recovery mode and plug the cable, nothing indicates on my PC that there is a device connected even device manager not showing any device connected... I am stuck now, I cannot install any rom to get phone life back.
don't worry! the biggest problem would be that you had no drivers installed!
nexus are super easy to recover and you can play with them safely (except if you flash wrongs kernels from other devices haha)
do what my mate gets up in the post! and it will fixed it.

It's not that it's not showing, it might already be installed correctly. When you have the Nexus 4 connect in fastboot it will show in Device Manager as 'Android Bootloader Interface' under the heading of 'Android Phone (see attached)

i've the same problem in my nexus 4.. Could u recover from that?

Stuck in recovery mode

Today, I wanted to reinstall the ROM on my Google nexus 4, and my phone was previously rooted months ago (with Google_Nexus_4_ToolKit_v2.0.0) and was installed with AOKP custom ROM. So I booted into the recovery mode, and accidentally I formatted the system, the cache, the data, etc. I thought when I connect the phone (in recovery mode) to my PC, the PC should recognize my phone and display it as a USB drive in my computer.
However, I was so wrong. With the right driver, the phone is recognized by my PC (as shown in device manager), but it won't show up as a USB drive. So I cannot put in any ROM/gapps file into the phone, I tried to use adb push to load the ROM/gapps into the phone, but I keep getting the "Read-only file system" error. I found the /storage/sdcard0/ can receive the pushed files, but in recovery mode, I cannot select these files for install.
I am now stuck in the recovery mode and cannot do anything. I need you guys help. How can I install a ROM now? thanks a million!!!!
Adb can only be used when your device is booted on android. If not then go to the boot loader and use fastboot.

Of course you are able to use ADB in recovery mode. Have you tried
Code:
adb push nameoftherom.zip /sdcard/
or if you are using a recovery where you are able to use adb sideload
Code:
adb sideload nameoftherom.zip
Then it should work. Or try mounting the usb in mounts/storage -> mount usb storage

Of course, it should work if the drivers are installed properly
Like others said use adb push to put a file on the device and then you can flash it with recovery.
If you don't have adb you can get it either by downloading android SDK or just downloading adb did

Try flashing back to stock, then just root and put your ROM back on, I've had to do it once before

Fastboot and adb not detecting My Nexus 7 wifi 32gb GROUPER

Edit : the problem is the usb cable itself.. Tried with HTC USB cable and its working flawlessly..!! Though it (original asus USB cable ) still works good for both charging, data sync and file transfers but not working for adb and fastboot..
Previously installed stock factory image (KTU84P) using fastboot (in boot loader)
then flashed twrp 2.7.1.1
rooted
rebooted and everything working fine.
to install a ROM through adb sideload
i formatted all partitions in recovery
started adb sideload but its in terminal adb is not detecting my device..
So i rebooted to boot loader (fastboot mode) to flash factory image but here fastboot not detecting my Nexus 7
is the problem with my nexus 7 or linux..??
i tried using windows but with no luck..
NOW My Nexus 7 doesnt have operating system dont know how to install one without using fastboot and adb sideload..
Did you try to use fastboot in Root privilege, I mean sudo in Linux?
