nexus 7 without ROM - cannot mount USB - Nexus 7 Q&A, Help & Troubleshooting

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....

[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.

[help] i bricked my nexus 7

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] Nexus 4 can get to TWRP, but no image/not able to communicate with PC

OK. I have spent the last 8 hours reading and trying my darnedest to get my phone up and running.
I wiped everything, and formatted data accidentally.
Now the phone wont mount the USB so I can put a ROM on it. I cannot get drivers to make either the skipsoft toolkit or the WugFresh tool kit to work.
I have read on ADB side loading, but cannot figure out how to get the phone to get recognized in order to connect with it. As it sets right now, I am stuck at the bootloader image, or TWRP recovery. No image on the phone, and I cant seem to get the drivers to allow my PC to see the phone. (Ive used WugFresh drivers, naked drivers)
Any help you guys can give me would be awesome.
Thank you
Mark
Hey there,
Our phones are MTP devices and because of that (I think) we can't mount them as a usb drive. But yea you can use adb sideload to get yourself up and running again.
For the drivers try this: http://forum.xda-developers.com/nexus-4/orig-development/toolkit-skipsoft-android-toolkit-nexus-t1995688
On your Phone:
1. Boot into TWRP,
2. Tap advanced,
3. Tap adb sideload,
4. Swipe to start sideload.
Once it says its waiting or something like that, it's ready to sideload from the PC.
On your PC:
Put the rom you wanna flash in the same folder as adb. So if adb is in C:\adb\ then put the file there.
In CMD type in adb sideload filename.zip (filename.zip is the name of your file you want to flash)
So an example would be:
Code:
c:\adb>adb sideload CARBON-JB-NIGHTLY-20131117-1149-mako.zip
It'll take a bit to transfer the file, but once it finishes you should be able to boot into the rom and use it normally again.
Hope it works for you, regards...
You can use Wugfresh to restore to stock and start over.

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?

Can't copy files to /sdcard/

Hello everyone,
I recently decided too install the LineageOS.
Everything went fine, but I forgot Gapps and didnt want too use my phone without them so I decided too install the ROM again but this time with the apps.
I followed the linageos guide but accidently wiped everything before I could
Code:
adb push filename.zip /sdcard/
(dunno if thats the problem)
Im using TWRP 3.1.1-1. I can get into Recovery Mode. While in fastboot modus my pc detects my phone as an OnePlus, in Recovery modus its just android.
Code:
fastboot devices
shows my serial number. OEM is unlocked.
while in recovery mode
Code:
adb push filename.zip /sdcard/
gets me
Code:
No such file or directory
Code:
adb push C:\User\...filename.zip /sdcard/
gets me
Code:
failed to copy.. remote couldnt create file
while in fastboot mode I get
Code:
no devices/emulator found
Copying by dragging the file into internal storage doesnt work neighter.
I dont know what I did different besides the wipe before the copying. Maybe the wipe deactivates USB Debugging?
Maybe someone sees where my problem is.
Thanks

I guess you don't have an OTG Drive.
you could always go 100% stock again and then flash LineageOS
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.13/
well first thanks for your reply. I flashed the original recovery and tried 2 sideload now. Seems to be driver problems. So I have to try every solution with Win10 and OP5 drivers I guess?
Make sure the Android drivers on your computer are up to date and also that you don't have any old drivers from a previous phone. I accidentally wiped everything on my OP5 once but when I connected it to my Windows 10 computer the OP5 was still recognized as a storage device--but I used TWRP not the stock recovery and also used the file explorer in TWRP. With the stock recovery you should still be able to side load flash the stock ROM from your computer. If you can't it's likely a driver issue.
I had once a similar issue, although not exactly this, just something with drivers.
A long process to fix was to install Linux as a virtual machine in Windows and that worked well. I could do all I needed, the phone was quickly recognized.
Virtualbox or VMware both are free/have a free version and I used Ubuntu.
Give it a try if all else fails.
