Greetings! I own a Nexus 7 from 2012, the Wi-Fi 16GB model. Two weeks ago, I found my tablet with its screen cracked, and, as I expected to be the case, the touchscreen has become completely unresponsive. My tablet has a pattern lock on it, so I cannot access my data to copy them on my desktop.
I have Android 4.4.2, my bootloader is unlocked and I'm rooted. I flashed clockwork 6.0.1.9 on it. Fastboot recognizes my device, I enter recovery mode successfully. All is fine, until I try to pull my files from the device, because for some reason I cannot access the sdcard mount.
Do you have any idea what I can do now? Any help would be greatly appreciated.
Get a USB mouse and plug it in then transfer your data to cloud storage like Google drive the other option if by chance you have left USB debugging on is to make a backup of user data via wugfresh nexus toolkit

First some background:
Playing around with some ROMs, I loaded up MIUI. I wanted to see what all the fuss was about. While installing from ROM Manager, the subsequent boot into CWM started my backup and installed the ROM. During the process CWM notified me the install was attempting to overwrite the recovery partition. I inadvertently said yes, one of the bad things about touch recovery...fat fingers.
Result:
CWM was blown away. MIUI failed to install Google Apps.
I connect the N7 up to my PC. It is not detected. No ADB available, however I can use wireless ADB so I installed ROM manager and reflashed CWM. This was were the fun began. Everything on my internal storage got nuked during the install and attempted recovery. I had to format internal storage.
No biggie, I have backups on my laptop through WUGFresh Root Kit. I will restore back to stock and start over.
Problem:
No computer I connect the N7 to detects it, regardless of USB connection method nor OS on the PC (Ubuntu, Win 7, Mint). I still have wireless ADB but that doesn't help with fastboot.
Current Status:
Currently I am running AOKP, after flashing multiple ROMs and Recovery between TWRP (current) and CWM. Also I have done many factory resets, cache cleaning, etc.
My diagnosis:
I think my boot, recovery or bootloader partition is borked due to the fat finger in CWM while installing MIUI. The added bonus...without being able to connect the N7 to any PC, I can't get into recovery unless I get lucky (1 out of 10 tries I get lucky and can get into recovery). I can get into recovery as long as I can boot into a ROM and do any common method to reboot recovery.
Question:
Now my question, does anyone have any ideas what I can do to get the USB connection working again to allow ADB/Fastboot connections?
Additional info/Review:
I have a GNex that I can ADB/Fastboot into without issue.
I have tried multiple different cables to connect to PC/Laptops.
As mentioned, I have tried multiple PCs to attempt a connection running everything from Windows 7 to variations of Linux (Mint and Ubuntu)
All the cables work fine with GNex, excluding one cable I deemed trashworthy.
I am fairly certain that the micro-USB port is fine, I can charge without issue even connected to a PC. OTG cable works perfectly fine.
I did something saying a port was open from the N7 that cause USB connection to fail. I forget what I did to find that message or what program I was using. I think I was trying to do a adb usb command from the command line on the N7.
USB Debugging is enabled.
More info:
No errors in logcat when connecting N7 to PC.
Try to do complete wipe & flash stock . My desktop has never detected the n7 but the fastboot works. I was able to flash stock using wugs toolkit.

That is the problem, I can't get any PC to recognize the n7 is connected. therefore, wugs root tool kit wont work. it uses fastboot and adb. without the drivers loaded and the device detected, I can't use wugs. this happens even on machines I have never plugged the n7 into.
If I could find a flashable zip of stock, that might do the trick.
I am wondering if I can use the otg cable and connect from my phone with adb? I don't think I can run fastboot commands from the phone though.

Doubt you could. Have you tried booting into bootloader then changing the usb port on the and also try reinstalling the drivers. When in bootloader try locating your device in device manager.
Good luck

even in boot manager, the device does not show in device manager on windows and it can't be seen on Linux either when looking for attached devices.
With my old viewsonic gtab I use to verify there was a device connected from command line, that doesn't work either. I'll post that command later today, just for reference.

OK, I have verified the problem is on the tablet side. I can connect my OTG cable to the tablet and mount my GNex allowing me to perform adb commands sent to the phone. I can not mount my tablet to the phone reversing the cable.
N7 ---> OTG ---> USB ---> GNex (works)
GNex ---> OTG ---> USB ---> N7 (fails, phone does not recognize the tablet being connected. I verified I could connect to a USB stick without issue.)
I think this narrows it down to MTP/PTP being disabled somewhere. Since it affects fastboot as well, I am assuming something in boot or bootloader. I ruled out recovery due to recovery working correctly when I can get to it.
Any ideas?
I dropped my N4 on the ground this past weekend and it now has both a shattered front and back glass. The digitizer does not work so I can't use the touchscreen at all.
Here's what I can share about the status of the phone:
It is still on, I can see the screen, and is fully charged receiving messages.
The power button and two volume buttons work.
The phone's storage is encrypted with the stock android encryption.
I have a 4-digit PIN enabled on the lock screen.
The phone did not have USB debugging enabled when this occurred.
I've tried to mount it to a computer to get the files, but nothing shows up as I believe I need to unlock it with the PIN before it will mount.
I can install apps remotely from the Play store.
I have the Sophos mobile app installed and configured but I don't believe there are any commands to UNLOCK the device, only to lock it and wipe it.
Honestly, I just want my data off of the phone and would rather not replace the screen and continue using it. I love the phone but it is way too fragile. Is there any way to transfer my data? I looked into connecting a mouse to the usb and using that to enter the PIN, but the N4 does not support mice. Since USB debugging was not turned on, I can't connect via ADB. Is there some sort of app I can remotely install from the play store to turn on USB debugging? Is there some sort of app I can remotely install to remotely unlock the device with my 4-digit PIN? If I let it die and then try to boot into recovery, will ADB work then? If so, how would I get the data off of the device if it is encrypted? Any guidance would be greatly appreciated.
Thanks in advance!
Is it running a custom recovery?
If yes, just go into recovery and do a nandroid, boot back into android and copy the backup.
If no, there's a thread somewhere with instructions on how to unlock your bootloader WITHOUT wiping your phone.
Unfortunately this is the only android phone I've ever owned that I haven't touched and left completely stock... No custom recovery, no custom ROM. I'll try to look for the instructions on how to unlock the bootloader without wiping the phone, but if I do a nandroid and boot back into android how will I transfer the data? I'd be stuck at the screen where I have to type in my encryption password, and even if I got past that I still can't mount the device in Windows to transfer the data?
Anyone?

The only way I can think is flash an advanced version of cwm (if it doesn't already have one) that has a file manager and make a backup, and copy the recovery to a location on the SD. Then mount USB storage and copy everything over.
Edit: actually, you could mount USB storage in cwm to copy files over, then make a backup through adb on to your computer, there's some tutorials on how to do that

as far as I know no. In bootloader mode is only fastboot, not adb

what i dont understand is how you cannot connect the phone with mtp... that should work without debugging.
EDIT: sorry, youre right, when the device is encrypted, you have to unlock it before mounting.
looks like you made pretty damn sure there is no way for you (or anyone else) to get access to the data on your device :/
although i dont know about unlocking without wiping. maybe that could work.

Google search a program called Motorobo; equivalent to what service providers use.

I have a Nexus 7 (2012) that I am trying to get to connect to a mac so that I can transfer some files and a backup, but it does not seem to be a normal problem. I can use fastboot just fine, and have verified this with -fastboot reboot. When I connect my N7 to the computer while it is turned on and on the home screen, it begins to charge, show the status bar 'usb debugging', but does not actually connect with MTP using Android file transfer or otherwise. I have tried different cords, reinstalling Android file transfer, usb ports, and a Windows 7 laptop with drivers from Wugs toolkit installed, but still nothing. I am running a stock rooted 4.3 JWR66Y with unlocked bootloader and TWRP 2.6.3, and have even opened it up to make sure that the micro-usb is not loose; It isn't. If someone could help me with this that would be greatly appreciated, and if I left out some information please tell me
Thanks
P.S Just checked before posting and I apparently have stock recovery back on.
Hi, I'm really hoping someone can please help.
I accidentally dropped my 2012 Nexus 7 and now the touchscreen won't work. I am trying to backup the data. The tablet turns on and my PC recognizes it when I plug it in via USB. However because I have a passcode on the lockscreen Windows won't show the files on the tablet until I unlock the screen. This is no doubt a security feature. Is there any way possible to either bypass the lockscreen or access my data another way?
I tried using SkipSoft Android Toolkit but for every option I select it says "Waiting for USB debugging to be enabled".
2012 Nexus 7
Android 4.4.x (Can't remember if it was running 4.4.1 or 4.4.2).
Everything is stock, no root.
Bootloader version: 4.23
The problem is that USB debugging is not enabled on the device, so I cannot use adb. Is there any way around this?
Any help is greatly appreciated.
Thanks
For anyone who might be caught in a similar situation, I was able to enter the pin code via mouse and OTG cable.
I have been searching for hours/days, can not find a solution. I recently unrooted my Nexus 7, 2012 WIFI to download and try the new stock Lollipop 5.0 . I found out the the 5.0 was too buggy and kept freezing up my Nexus. I decided to revert back to 4.4 using the nexus toolkit (as I have many times in the past) and in the process lost my recovery option while in bootloader mode (was on a friends pc and had loose USB cable). Because I can not access the system to enable USB debugging. I am now on my own PC using a good USB cable I cant get ADB to recognize the Nexus. I have tried many drivers. I am thinking this is considered a hard brick scenario. When I do a reboot in bootloader mode, I get gray screen. When I try using recovery, I get dead droid with upside down triangle. Any help would be appreciated. I am not a rookie at this but also not a pro so I need help.
Remember, I do not have USB debugging enabled, nor can I boot up to access dev options. I can go into bootloader and adb modes but can not get adb or nexus toolkit to recognize. Thanks
Anyone?
