[Q] Fastboot Recovery - No USB recognition - Nexus 7 Q&A, Help & Troubleshooting

Hi all,
first of all - sorry for my bad english.
I have the following problem with my nexus 7:
the device is rooted and has the clockworkmod recovery installed, the Android version is 4.1.1.
My Computer stopped to recognize the tablet when i connected it, and it is not listed in the device manager anymore.
I tried different USB-ports, cables and even computers with no result, but OTG with Stickmount still worked.
So i tried to install a rom via clockwork mod, but the installation process aborded.
When rebooting the device stucked at the white google logo and still does.
I can go into fastboot mode but if i choose "recovery" i will get back to the google logo forever again.
I found this thread (http://forum.xda-developers.com/showthread.php?t=1773431&highlight=no+usb&page=2)
with instructions to flash the factory image via fastboot mode.
Now the fastboot command from the console shows also no result.
But i can´t install the driver, because my tablet isn´t recognized by my pc in any way evon not listed in the device manager.
Any Ideas?

HELP - recovery issues. Unable to flash any ROMs

Months ago I flashed a Modaco custom ROM to my friend's San Francisco. There haven't been any problems of late, however today I attempted to flash a Froyo build so he can try out C2DM apps like Beejive and Facebook and I was unable to load up a recovery screen. When holding Vol DOWN and booting I just got a white rectangle with FTM inside it - indicating that there was no recovery image installed.
I tried flashing Clockwork Recovery with the ZTE Blade Recovery Manager 2.9 but it kept saying 'Unrecognised' after selecting the .img file, no matter which one I used or whether I changed the name or screamed 'hail Mary'. I attempted multiple reinstalls to no avail.
The device is rooted so I tried using Terminal from the Android Market and flashing the recovery image but although it didn't come up with any errors I was still unable to boot into the recovery image. All it does now is show a green android the same as it would if pressing VOL UP when booting.
I've even tried installing with fastboot for mac, but despite being able to input the necessary commands, fastboot doesn't flash the device and just sticks at 'waiting for device' when the recovery flash command is executed. I've tried connecting the device a number of times, rebooting etc. I have no other USB ports available and no access to a Windows pc at present.
Can anyone assist here? The phone still works fine with the Modaco ROM but it's a bit annoying if that's all he will ever be able to use now!
Thanks in advance.
Japanese_Jellyfish_RLS9_image.zip should be easy, and it installs recovery as well. Please read how to install it.

Nexus 7 stuck at Google Screen (Even when Recovery Mode)

Hello,
I recently unlocked, rooted, and CWM (Recovery) my Nexus 7 and everything seemed fine with a custom rom installed aswell.
Just now I edited mymedia_profiles.xml for 720p video mod and rebooted device now stuck at google screen. Even in bootloader when I select recovery it goes strright to google screen and stays stuck.
How do I fix this
If u can't get into recovery u could flash the nexus 7 stock image

when in the boot loader, plug in via USB then press recovery.

Thanks all for help sorted it out.
Re flashed the custom recovery using adb fastboot (Google Nexus 7 Toolkit) all fine now but strange that recovery failed.
After editing a xml file
Its a bug with the 7’s bootloader. You can't get into recovery directly from the bootloader without having the USB plugged into a computer or you can just select reboot into recovery from the power menu on PA or any CM based rom. There are a couple of apps that allow you to reboot into recovery as well like rom manager and rom toolbox... The modified XML file had nothing to do with it.
Hello everyone,
I just installed TWRP via goomanager and when i use "reboot recovery" in goo manager menu: TWRP works fine.
But when i use ROM toolbox lite for reboot into bootloader then i chose simply "Start" or "Recovery mode" i'm also stuck at google logo...
I don't understand one thing, we only can enter into bootloader mode with an android app, we can't do that when we power on the tablet for the first time?
Sorry for my approximate english.
Yes that is correct. Its a bug with the boot loader. You can plug the 7 into a computer USB and it will let you into recovery from the boot loader. This WILL NOT work with a charger though... I know it sucks. Hopefully Google will fix it in future updates.

For all those who have problem getting to recovery mode after connecting the USB cable to computer, follow the "Configure Drives" step from this link.

Its worth reinstalling the drivers if its already installed.

HELP! Nexus 7 Stuck at X Logo - Unlocked Bootloader and installed CWM

I tried rooting my nexus 7 (16GB 2013) with 4.3 installed on it today and I ran into an unusual error - It is stuck at the X logo after booting.
I have successfully unlocked my bootloader and installed a custom recovery - CWM v.6.0.3.7. I can access the bootloader and get into recovery mode fine. My nexus 7 is also showing up as an Android device only while in the bootloader - When I get into recovery mode it shows up as a portable device with a yellow exclamation mark next to it on my computer's device manager.
The problem is I'm not sure how to transfer any files to it in order to install any roms/fixes/etc. I can't boot and when I connect my tablet to my computer, while in recovery mode, it will not show up as a media device - So I'm not sure how to transfer any files to it. Also whenever I try performing a backup on CWM it gives me an error saying: "can't mount backup path." For some reason CWM can't mount my sd card, which I don't understand either. I'm hoping this is an easy fix, maybe I forgot a step but I don't want to try anything else yet without gathering more information about my problem. All I've done so far is installed the Android usb drivers on my computer, enabled USB debugging, Unlocked the Bootloader, and then Installed Clockwork Recovery Mod v 6.0.3.7. After the last step I am unable to boot or transfer files to the sd card.
Any help or suggestions are welcome and appreciated. Thank You!

If you can get your PC to recognize your phone with the phone's drivers installed, then you have hope. If you can still get into android itself, install twrp installer from the Play Store. Update to the latest recovery from there (assuming your rooted).
If you cannot get into android, but when pressing volume up while plugging a usb cable connected to a PC in, your phone is recognized by the PC, you have to flash the stock KDZ file using the R&D test tool that floats around on these forums. It will unroot your device, but it will give you the chance to start clean and unharmed.
For me, I have to send mine in under warranty because now my G2 doesn't even pop up on Windows or Linux.

phone bricked while trying to go back to stock rom

hello,
as the title says, my phone bricked while trying to go back to stock rom. this is what i did: i had a well working meticulus custom rom + the meticulus twrp recovery on my phone. thing is i need the google apps and they are not supported on meticulus roms. so i tried to go back to rom, downloaded a stock rom and tried to flash it with dragging it onto my sdcard and installing it from there. so this is when it bricked, the huawei logo appears at the start but it stays and nothing will install.
i tried to reinstall the adb drivers, no success. i can only use the bootloader but i can only flash a recovery, after trying to boot into the recovery via fastboot boot recovery.img it won´t do a thing. also the recovery is stock recovery all of a sudden (erecovery). and there i only have the option to "download latest version and recovery" but that gives an error aswell.
i´ve tried to reinstall drivers, no luck. when i do a fastboot devices it shows my device but when i do adb devices it doesn´t show up anything. so the usb driver is somewhat corrupted. my computer detects the phone when in fastboot only.
i´ve tried to reinstall the drivers a hundred times, i can´t get the phone to work anymore.
i would really appreciate it if someone helps me out.
