Because I don't know what app it is I have no idea what it did so what I would do is go to recovery and do the following command to every file you want:
adb pull /sdcard/Some_file.txt C://Users/Your_name/Desktop/Some_folder/Some_file.txt
If possible you can make a backup of the internal storage and restore when you reflash your rom or something if you have TWRP also moving the image file to your PC using ADB Pull.
After backing up you have to use this tool with your device on the bootloader menu: https://developers.google.com/android/nexus/images#occamjwr66v
You can restore your files afterwards but if you originally used a custom rom then flash the custom rom.

Unable to default factory reset

Hi guys. I have been trying to fix this problem for like 10 hours but I could never get it right.
Device status: Rooted, unlocked bootloader.
Currently my problem is that whenever I factory reset my device it goes back to CWM recovery. I tried using mskip toolkit and Wug toolkit to flash back to stock rom but it didn't work. The thing I realized is that I could never mount my sdcard from the CWM recovery.
Besides that, whenever I push some files into my sdcard through Windows and reboot my Nexus 7, the file gone missing. I also tried to install and uninstall app and it seems to be working at first, but it goes back to the default state after rebooting it.
By the way, I am able to fastboot it and enter CWM recovery and boot like normal, but could never edit anything on it, not even flashing.
Things I have done:
-Flash stock rom(full zip file) using mskip and wug toolkit.
-Flash stock rom part by part(boot,recovery,system,userdata)
-Boot image using TWRP and wipe data.
-Flash custom rom using toolkit(Bugless Beast).
-Downloaded twice for the stock rom and checked with md5sum.
Things going on now:
-Back to same state no matter what I do to the device.
Sorry for my English.
Anyone help please?
Hmm that is kind of weird, what system are u using? Windows Mac or Linux?
Try using Nexus 7 Toolkit 2.0, it works great in my case :s Restore to stock rom using it. Also check the console if there are any bug report.
Btw you could try to lock/unlock your bootloader as it wipe all user data at the same time
Good luck!

Thanks for the reply! I have tried both mskip and Wug toolkit and it doesn't work.
The data inside the device is basically uneditable right now! No matter I delete or add in new files and reboot, files that deleted will be back while the files that I added in will be removed. Seriously I need some help, I'm unable to flash rom or do anything with it since I have unlocked the bootloader(and unable to lock it back) and warranty is voided.

[Q] Help, boot issue

Hi everyone,
So I have never ran across this issue before. I haven't had any problems with my device and yesterday I wanted to test out the new Jelly Bam update rom from their site. The rom would not boot pasted the "Google" spash screen so I rebooted in to recovery and did a full wipe and restored via backup to my previous rom just like normal. Well then I noticed that normally when I connect my phone to my computer I see my internal memory drive pop up which I am able to click on and then access my files, but this time when I accessed it I have a hand full or folders like 0, twrp, android, etc and I had to double click on o folder to access my memory with all my files. I thought that was weird so I went on about my day. Later I tried to do a fresh install of my current rom PACman but even after doing a fresh install the phone will not boot passed the Google spash screen, and now twrp doesn't even see my backup file because its being directed to this new partition with all the folders I was talking about. I even tried using the file manager in twrp to move the backup to that twrp folder but twrp doesn't even see it.
So as of right now I can get in to twrp but I can not boot my device pasted the google splash screen. I also can't access my memory through my pc since nexus does not allow it with twrp. What do I do? My thoughts are that something got screwed up with the partitions when I flashed the Jelly Bam rom so I will need to go back to stock, does that sound about right? I was thinking of following these instructions to go back to stock and then move on from there, any thoughts or alternatives? http://www.androidrootz.com/2012/12/how-to-unroot-nexus-4-to-stock-42-jelly.html
Thank you
Trying this method to return to stock: http://www.wugfresh.com/nrt/
If no one has any input I will assume I am following the right path.
I flashed factory images a couple weeks ago and in order for TWRP to see the nandroids I copied back to my phone I put them in the following path: /sdcard/TWRP/BACKUPS/stringofrandomnumbersandletters/
Are your TWRP backups in a similar location?
If you've decided to go back to stock, I'd suggest using the following guide by efrant... http://forum.xda-developers.com/showthread.php?p=34552123

It is twrp fault. That recovery is crap to be honest.
Sent from my Nexus 4 using xda premium
It looks like twrp is now looking at my twrp folder in my sd card 1 not sd card 0 where I have had my backups and all my files. After trying again, I moved the TWRP backup to the sd card 1 twrp folder, twrp recognized it and I restored from backup....but when I reboot I am still stuck on the Google screen. Not sure what to do.

Since I can't move anything to my memory, any suggestions?
If you've got adb and the proper drivers installed on your PC you could try:
Code:
adb push ROM.zip /sdcard/ROM.zip
from the command prompt. Obviously use the name of the actual ROM.
Edit: ignore that, just read the post where you managed to restore! D'oh!
Have you tried clearing both caches?
The only issue is that my phone is not recognized as having debugging on when I use the Nexus Root Toolkit. Would it matter trying to push via adb? Also with your code, can you specify exactly what I should type. Mine shows C: \Users

If I were you I would not rely on a toolkit at this point. If you boot into recovery you can use adb commands to push the files from your computer to your phone.
Edit... Spec-Chum's suggestion of wiping caches is a good one. Have you tried that while booted into TWRP?
You could also try the following from within TWRP:
1. Factory reset
2. Wipe system
3. Restore nandroid backup
4. Wipe caches
5. Reboot

And that's were I am stuck right now. I am not a pro at using adb commands, never used it till I got my nexus 4. Right now when I launch the cmd it shows "C:\Users\My User Name\Desktop>", not sure where to go next. I guess I am not sure what I should be pushing at this point either.
Oops...it seems I was editing my post at the same time you were responding to it...take a look at my previous response again
I'm fairly new around here but I can help with the adb commands if you need. Hang in there

Yeah. I tried wiping cache/dalvik/system/factory reset and then both restoring from backup or flashing the latest PACman rom which is in my sd card. Right now I am reading the http://forum.xda-developers.com/showthread.php?t=2018179 guide to see if I can use adb to flash my rom or another recovery. Makes sense if its the recovery not letting me flash anything, but i'm not a dev. At least I am able to get in to recovery to begin with, good sign I guess.
If you can boot into bootloader and recovery there are many options to help get you up and running again. That guide by Jubakuba is really good but if wiping and restoring your backup from within TWRP didn't work I would highly suggest reading efrant's guide on returning to stock...I posted the link in an earlier reply.

I was able to flash cwm using adb, now trying to do a fresh install
Nope, doing a fresh install didn't work. Now its time to restore to stock. ......
One problem:
"
5) Extract the files from within the .tgz file which you downloaded in step 3 using 7-zip, not WinZip or WinRAR or whatever.
6) Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;"

Its weird adb will not work on the computer unless the files are in the platform-tools folder in androi sdk. trial and error, just finished flashing system....
should I do this command, I really don't want to lose my stuff:
10) Optional (NOT optional for n00bs) -- Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
Well, I didn't and finished the process...did a reboot when I was done...now its on the Google screen...just waiting....I'm seeing a Nexus X splash screen!!!...
Update: Its taking a very long time, hopefully it works...going to give it another 10 mins
And we have BOOT... thank you everyone! Now I have to root this sucker!

[Q] Need some help please

I have a Nexus 7 wifi, It is stuck at the Google screen boot looping. It is unlocked and has TWRP 2.5 which I can access. I have tried every tool kit to no avail. Need some help please!
dont use a toolkit
get to a command line and figure out whats wrong by trying to flash a factory image, or run factory reset in recovery and see if it fixes it.

I tried factory reset but it fails. I tried to flash a factory image through side load but it fails.
If I go to advanced wipe and do them one at a time they all work except data.
It appears to have nothing on intrenal or external storage.
One other thing is when I try to mount the system in twrp it asks for a password?
I have never setup a password so I don't understand this.
Thanks
Did you encrypt your device?

No, not at all that's what's so strange.
I purchased it new and it started locking up and after an attempted factory reset here we are.

Factory reset would wipe data partition leaving nothing in data. Makes sense that it wouldnt let you wipe that when there is nothing there.
Try flashing a factory image from fast boot. Not from recovery.
Sent from my Galaxy Nexus
Would it not have to be loaded on the device? I tried it with a tool kit and it gets to the end and fails on verification.
I don't remember what version it was so that doesn't help. I think it was 4.1.2
But not positive.

Okay seems to be a problem with twrp 2.5 as far as the password I'm downloading 2.6 now.
Use fastboot to flash new recovery and system partition. You run fastboot commands from your computer not from recovery and your device needs to be in bootloader not recovery. It does not require you to load it onto the device prior

I wiped my phone without a rom

So, I wiped my phone and didn't realize that the rom I was about to install was corrupted (I think the download didn't finish) and I forgot to do a backup, what can I do to recover from this disaster?
Use Nexus toolkit.
Two easy options:
1. Use adb to push a rom to your sdcard from your recovery then install like normal
2. Use fastboot to flash a stock image your system partition
Download a ROM that's not corrupted and place it in platform tools folder (where you have your adb is located) and just go to your phones recovery and sideload

Thank you to all of you, I used Wug's Toolkit (NRT) and it worked.
Similar Problem
My problem is similar but a bit different.
I flashed CWM over the top TWRP and when I re-entered custom recovery and I went in to install a zip from sd not all my folders where showing including the folder I keep all my roms in.
When I try to boot back in to system it just takes me back to recovery.
Am I being a noob or is it something gone wrong?
Thanks in advance!

wipe everything

hello
i wipe evrything on my phone
and want to flash purity rom again
but i dont know how to transfer the ROM zip file to the phone if there is no OS ??
Do you still have custom recovery eg. TWRP or Clockworkmod?
If you have a custom recovery, you should be able to flash the ROM from your PC using ADB, or possibly copy the ROM zip from your PC to the Nexus while it is in the Recovery menu. (My PC recognizes my Nexus as removable storage, so like a flashdrive, when plugged in while in the CWM menu).
