I made the dumb mistake today of flashing my Nexus 7 with the wrong gapps and as a result setup would continuously crash.
I first tried to reboot into recovery by entering fastboot mode (power + volume buttons) but all i got was the google logo for all eternity
next I tried reverting to stock with the nexus 7 rootkit but it always failed on the fastboot check saying my device could not be detected.
Assuming my drivers were not working correctly I manually installed the google usb drivers and at this point if I look in the device manager I see Android device > Android Bootloader Interface but if I run the adb devices command I get nothing.
I feel like I'm at the end of my rope here so I could use any suggestions.
p.s. usb debugging is not enabled because I had just done a factory reset and I can't enable it because I can't really access anthing after booting up.
solved
Ok so after installing the google driver I decided to give the root tool and leaving my nexus 7 plugged in for a while I noticed that the fastboot screen was no longer frozen and decided to try the rootkit again and this time it worked like a charm so problem solved!!!
I guess I couldn't detect it with adb because usb debugging wasn't enabled but the rootkit was still able to restore it using the fastboot method.
I'm trying to use the Nexus Root Toolkit to do some work on my original Nexus 7, but I'm having driver issues.
A few notes:
The device is rooted running CM 10.2 (might be irrelevant)
My PC is running Windows 8.1 and is fully up-to-date
My PC does recognize my Nexus 5 with no issues. (rooted, stock)
I've tried MULTIPLE times to use the Nexus Root Toolkit's Driver Configuration Guide to get my drivers working with absolutely zero luck
My PC is recognizing the Nexus 7 in the "Devices and Printers" menu and I can access it as a mounted drive when USB debugging is disabled
I'll provide more information if I can, but I'm really beginning to get frustrated with this.
My device is showing up in the Device Manager as a "SAMSUNG ANDROID PHONE" device, which makes zero sense.
Please help?
so i have a nexus 7 stuck in a bootloop, i never enabled usb debugging, and cant get my pc to recognize the device even when it says it's in fastboot mode. bootloader is still locked and recovery mode freezes at google screen on the rare occasions when i can even select that option. tbh i think there's something wrong with my adb setup, but i followed the instructions on the android sdk site... kinda lost here sorry if this question is unclear. i also tried using the unlock option on wugfresh's nexus root toolkit but it keeps saying there is no fastboot device attached. any help would be much appreciated.
never mind, I'm just going to install a fresh motherboard.
Hi everyone !
I got a tricky situation there and I need some help. (I googled a lot before posting this.)
Few day ago I tried to root my Nexus 4 using Nexus Root Toolkit.
I'm going to explain step by step what happend :
1. My phone was on Android 4.3 stock rom and I unlocked it with NRT.
2. I did all updates from OTA to get Android 4.4.
3. Then I’ve made a HUGE MISTAKE because I've rooted my phone with the wrong modele selection in NRT. (Android 4.3 was still selected, but my phone was actually in Android 4.4).
4. While rooting, "everything was fine" exept that I’ve got a black screen just after the “Bootloader” and then nothing happend.
5. I’ve restarted my phone manually, by pressing the Power button 5 seconds. It worked, my phone actually booted but it was normal/not rooted.
Since that, ADB doesn’t work anymore on my phone.
ADB was fully functionnal before and I think I have soft-bricked something in my phone.
The problem is not my computer because :
- Yes, ADB is enabled on my phone and I tried unplug/plug USB many times. (doesn’t work)
- I've tried other USB port. (doesn’t work)
- I've tried drivers reinstallation on my computer, and restarting it many times. (doesn’t work)
- I've tried my phone on differents computers (doesn’t work)
Details :
- The “Stock ROM + Unroot” option on Nexus Root Toolkit worked (throught Bootloader mode) but ADB sill doesn’t work.
- I've tried to launch a custom recovery from Nexus Root Toolkit using Fastboot mode but I also get a black screen.
- In the stock recovery mode, the option “Apply update from adb” seems to work. (The drivers test of Nexus Root Toolkit pass, but I need to restart my phone manually to get to the Bootloader mode test.)
Any idea what I can try now ?

I foresee a total wipe in your future. First try uninstalling all the Android drivers in the Device Manager, turn off debugging on the phone, plug the phone in, and see what happens.

Hey ! Thanks for your repy
I tried what you told me, I uninstalled everything related to Android drivers on my computer in Device Manager and with USBDeview. I also uninstalled "Universal ADB Driver" and I restarted my computer.
I pluged my phone back in without USB Debugging and Windows reinstalled every drivers itself.
Everything worked fine, so I've installed "Universal ADB Driver" from NRT, and follow it instructions.
Then I've enabled USD Debugging, I unpluged and pluged back my phone and tried the drivers test.
But ADB still doesn't work...
Windows detect my phone, but my phone doesn't dectect my computer (it doesn't ask me if I want to accept this computer as it should do.).
yo,ve tried to reinstall NRT and to redownload the android sdk
uninstall NRT using iObit Uninstaller (it will totally delete any NRT file from HDD)
after uninstalling it wirh iObit Uninstaller shift delete on android sdk folder
restart
and now download the Android SDK 32bit (even if you have 64bit os download 32bit version is totaaly stable and compatible with the drivers)
open android SDK and install google driver
then install NRT
another thing to do is to change the usb port (allways to be an USB2 port and use the cable that camed with the phone
GOODLUCK
Try to get into fastboot power+volumes then go into toolkit on root and all should be fine

Hi all,
After a long time, I decided to play with my Nexus 7 again. About a year ago, I bricked itsomehow (don't remember how exactly).
As a result, only the bootloader is installed. So no (custom) recovery and/or ROM. Today, I tried to flash the stock rom with the Nexus Root Toolkit but it didn't work.
My computer (Win 8.1) was not able to recognize my Nexus 7 in fastboot mode.
The device manager in windows labels my nexus as an unknown device of which the device descriptor request has failed.
I already tried to install many different driver packages (while removing the device from the device manager) but it did not work for me. Everytime, the tablet is seen as an unknown device.
I also tried to update the driver manually by right clicking on the unknown device in device manager and clicking update driver software and then manually selecting this http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2 driver but it does not recognize any driver.
So in short, my pc, which runs windows 8.1 is unable to see my Nexus 7 (which is bricked and has no rom nor custom recovery installed) when it is in fastboot mode. Therefore I am unable to install another rom.
Any thoughts on this problem? Thanks in advance.
I sent you a PM regarding this issue and a potential fix. If it works, i'll post the detailed info here later
