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!

Have you tried installing the patched bootloader? Remember, you have to have your SBK number you got from your UID. I found that NVFlashing using one of the earlier releases works best for me.
Also remember what OTA update.zip you are installing. Some of them, are just update patch files, which require a specific OS to be installed.
Did you try this thread?
http://forum.xda-developers.com/showthread.php?t=1699277
Basically, you decrypt the 2 update files, extract the contents of one on to your SD card. Try booting to stock recovery and see if it installs and boots.
If that doesn't work, then do the same with the other update file.
The 50x is basically bullet proof. There is always a method, and sometimes, it's finding the method that works is the hardest.

I did finally get it. I let it bootloop hooked it up to my pc and used adb while it was bootlooping to get my cpuid and sbk since i had neither of those i couldnt do jack with nvflash. After i got those went back in apx mode flashed bootloader and cwm again followed thors instructions on how to really format data partition and installed rom like normal. Worked like a champ, but without cpuid and sbk i woulda never fixed it

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.
if the above does not work try this toolkit. http://forum.xda-developers.com/showthread.php?t=1809195

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.

Hard Reset Nexus 7 Working
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.
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?
Long story short. My son went into recovery (TWRP) and wiped my rom. Not im looping at the google screen. I can access twrp and the fastboot screen. I tried to use the nexus 7 toolkit to restore it but it tells me the drivers are not loaded. I have tried everything I know. Every step to loading drivers says to check usb debugging...but I can't even boot a rom because I haven't got one on the tablet. Is there a way I can load a rom even though the tablet won't boot?
Using the NRT, check the box for boot looping/soft bricked, then flash the ROM. Using TWRP, mount USB storage in advanced, transfer the ROM from your PC, then flash.
Mounting USB worked! Thanks!
hard reset my phone via twrp recovery and i accidentally wiped the system too. now when i try to reboot my device, it's just stuck on google logo. bootloader is still unlocked. fastboot and twrp are working perfectly too. i just can't figure out a way to push zip file to my phone. i trie using a couple of toolkits and all of them were stuck on device not found. any help would be greatly appreciated.
Boot into twrp, connect phone to the computer, copy rom to the phone, and flash from twrp.

i'm a windows user & my laptop doesn't recognize my device when i connect it. probably because it requires usb debugging to br turned on which i can't do because no os.
