Possible Bricked Nexus 7 Please Help!

Hi guys,
I could really use some help. I have researched this for a couple hours and could not much information on the subject. I rooted my nexus 7 and I was attempting to flash a ROMbut I don't think I installed it right so I tried to restore it from the recovery tool but as the device rebooted it just got stuck on the Google boot screen/logo. The reason I was trying to recover it was because when I installed BAMF ROM through ROM Manager it would only me install one file at a time so I just installed the main ROM file and then I figured I would install the Google apps ROM file and the patch. The reason why I did this was because before I tried installing all the 3 files at the same time using twrp2 and it created same issue but instead it would go as far as the nexus logo and just hang. But I managed to restore/recover it. Well after I installed the BAMF ROM everything was working great EXCEPT there was no Google apps! It wouldn't let me setup my Google account and just download my old stuff. There was nothing on the screen except for a couple apps but I couldn't see the ROM manager or anything else. So I was stuck so I decided to just try and recover but I think something went wrong. Ok...now that all that is out of the way here is what I can do.. When I try to get into recovery or fast boot mode it works BUT then I try to access the recovery mode and it wont let me. It will just reset and go to the Google loading screen and hangs. If I plug the device into the USB I can hear the ding but I dont see it come up on "My Computer" under devices. I have read that you can still recover a bricked Nexus as long as it comes up as Android ADB Interface (Unspecified) and when I look at its properties it gives me a Hub and Port #. Is there anything I can do to fix it??? Any advice is greatly appreciated!
I attached some images for what its worth..

Boot loader okay, plug into computer and try accessing recovery through boot loader again. It should work as there is a bug in the boot loader.

You have to use the factory image Google has provide to get out of this. Google search on how to use the factory image. It will erase and reset your nexus 7 like if it was straight out of the box.

Nexus 7 not booting..

Hi folks,
Typical newbie here.. i had my nexus 7 unlocked/rooted and flashed custom trinity kernel. All working great until i decided to apply the 720p video camera mod by going into the system/etc folder and editing the /system/etc/media_profiles.xml file directly. I thought I did it correctly and set the correct permissions but when i rebooted the nexus , i get the trinity boot screen for about 30 seconds, then a screen flash and then nothing.
I can reboot in clockwork recovery - but unfortunately I cant seem to be able to connect the nexus to a laptop we have her at work. I downloaded the nexus 7 toolkit and tried installing the windows 7 drivers but it failed. I'm not hoping when i get home and connect it to my own PC which already has the drivers it will recognise it and allow me to copy a zip file to the sd card so i can flash it.
I was also wondering if there is a way to completely reset the Nexus 7 without connecting it to a computer inside clockwork recovery?
Cheers,
Mick

Restore a backup in CWM? You do have a backup right? Or... assuming you have a ROM zip on there, you could wipe and reflash.

did you mak a NANDroid of stock? or any nandroid for that matter? just restore one of those from cwm. if that doesnt work, just flash any rom you have on your tablety

afraid have neither a rom or nandroid backup... all good lessons learned.. will try from home and see how i get on..

got sorted, was able to use one of the tookits to 'push' an update.zip file to my nexus 7 and flash using clockwork recovery.. needless to say once back up and running i've since done a nandroid and rom backup and backed up all my apps with titanium backup... also flashed CM10 last night..
can i ask what's the most efficient way to use Titanium backup when flashing roms? If i take an apps/data backup.. is there any point taking a system data backup if i'm flashing a new rom?
Last night i flashed CM 10, then flashed gapps to get back into the play store.. then downloaded titanium backup, ran my apps + data restore and eveything was back as i wanted.. stuff from the homescreen had gone etc.. but i guess no way around that?
also how does backing up/restoring to google drive work with titanium backup?
cheers,

Mine nt booting too
Well i also got ma nexus 7 today nd when I firstly tried to boot it up it didn't boot up instead rondom coloured line started to show up. I tried to boot into recovery but I wasnt able to do that.

Stuck at google logo, recovery mode doesn't work?

I seem to have messed up the process. I successfully unlocked and rooted my Nexus 7 but during wipe process using JROM flasher something didn't go right and now I'm stuck at the google logo screen forever. I can boot into fast recovery mode but that's about it. I can't do anything.
I've had this done before on my nexus phone but it seems I managed to f it up this time.
I thought I had a rom zip file copied on to the Nexus 7 but it doesn't show in the menu. Now I'm stuck at the logo screen not having access to any roms to install. How do I reset all of this to factory? I've already checked most of the threads regarding this and haven't been able to find a solution yet.

before you do anything, use your recovery to see if the rom zip is located in /data/media/0/. if its there, flash it from that location.

Are you able to boot into recovery?
If yes, it could be as simple as plugging your tablet into the computer and mounting the usb, drag and drop the rom, and flash it without using a toolkit (only recovery). I'm not familiar with jrom flasher, but i will say the more variables there are, the more chance of a problem.
If no, you're best off running the stock factory image through your computer, found here: https://developers.google.com/android/nexus/images#nakasi. I had your problem at one point, and could not even boot into recovery. After trying to install cwm through adb (which failed), and a number of toolkits, the factory image was what brought my nexus back to life.
I remember reading that sometimes a wipe can delete your recovery as well as your system (and whatever else you have on your n7), although i dont know if that was ever fixed, as i got my tab replaced a month or two ago and havent rooted it again yet. There was some type of command or .zip or something that should be used to keep recovery after wipes. When i expirienced problems such as yours, it was also from a bad wipe from a toolkit. Using just the recovery afterwards, i never expirienced any issues, even without the recovery fix.
I would definitely try simms suggestion first if you can access recovery. If that fails, try one of the above processes.
PS, even if you can access recovery, if at this point you just want to go completely stock, the factory image will work regardless.
cheers

Thanks for the help guys, I've been struggling for the past 3~4 hours but I found a solution.
What I did was use JROMFlasher and upload a rom zip to the sdcard directly and go from there.

[Q] Need help restoring my N7 after a crash...

Yesterday my N7 'crashed' on me...
Device Info: N7 32gb non-3G, Android 4.2.1, Rooted via Toolkit, Stock, CWM v6.0.1.0 (non-touch), Bootloader 4.1.3 Unlocked (of course)
Recent changes: I had initially installed a 2nd account for my son to play games on without messing up my progress shortly after 4.1.2 launched... I immediately noticed that the N7 seemed more sluggish but put up with it so he would have his own account. Well he hasn't used my N7 for weeks and I hoped that maybe if I uninstalled that 2nd account that the sluggishness would go away... So a few days ago I went into settings and removed it... Not sure if it made a big difference. I only mention this because I am not sure if it had anything to do with what happened yesterday...
The Crash: Yesterday when I came home with my N7 I heard some notifications letting me know that it had logged into my home wifi and had connected with Gmail... About an hour later I went to use the tablet and when I hit the power button I briefly saw the wallpaper and unlock pattern. Almost immediately the wallpaper disappeared and was replaced by blackness. I could still see the unlock pattern and then the screen 'shifted' - got smaller, bigger and then bam... the tablet reset. This whole thing took just a few seconds.
After that it seemed to be stuck at the nexus logo/animation... I assume it was stuck in a boot loop. I let it go for a good 30 minutes and nothing changed... still had the animation. At that point I did the following:
So I rebooted into the bootloader and rebooted from there... same result.
So I rebooted into the bootloader and then recovery and rebooted from there... same result.
I gave up in frustration and powered it off from the bootloader and went to bed.
Today I went back into recovery and did a Nandroid backup. It gave me no options, it just did a full backup. Based on the amount of free space that was reported it seemed as if my SD card partition was intact. Up to that point I didn't know if the glitch maybe wiped everything out...
After that I formatted the /cache, /system and /data (not sure of the order). Then I tried rebooting and now it won't go past the Google screen with the unlock icon.
So I went back into recovery to see if I had a zip that I could flash. The only one there on my SD card that I can find is the CWM/Superuser one from the toolkit. That file is named CWM-SuperSU-v0.94-signed.zip and is in the root directory. I checked and the Nandroid backup seems to be where it should be...
So I figured that I need to flash the factory image but cannot seem to mount the N7 via USB. When I plug it in my Windows 7 machine, Win 7 lets me know that it has installed the "Nexus ADB" driver that my N4 installed and seems to be connected. But there is NO /USB in the Mount menu in Recovery and Windows 7 doesn't see the N7 from the My Computer/Windows Explorer.
My Questions:
Do I need to 'push' a stock image via ADB?
What ADB command do I type to see if the N7 is in-fact accessible from my Windows 7 machine?
I am assuming that when I formatted the three partitions mentioned above I wiped the boot ability of the N7. Is that why it won't go past the Google screen now?
Did I do anything wrong in what I've done so far?
Thanks in advance!

Use this tool to connect via adb and restore stock+unroot then after re-lock the bootloader, this will give you the same state as when the tablet left the factory then re-root and start over

Will I lose the SD partition?
My Nandroid backup isn't backed up anywhere else...
That was the first thing I was going to do after connecting the dead N7 to my Windows 7 machine...
Nervous about that aspect!

Yes locking and unlocking your bootloader will wipe all data as far as Im aware. I dont know how viable your Nandrid backup would be regardless though. It was made after the boot looping errors occurred right? That would probably mean restoring a back up from that time frame would reapply all those errors. You could try to pull your nandroid back up using adb to see if theres anything salvageable from it and Id redo everything on your device. Heres a link to a bunch of useful ADB commands which may help ya out. ADB useful commands

That is true. As you can tell I am semi-knowledgeable but not as proficient as many.
So I thought that the Nandroid backup was divided into different pieces... And that I could choose which pieces to restore and by doing that, just restore the portion of my tablet that represented the 'setup' (apps, layout, etc) but not the OS... Maybe I'm wrong about that...
As for ADB, yes, I thought about that as well and already did an ADB Pull to grab the Nandroid ... now I'm doing one to grab everything on the SD Card.
Thanks for that!

Yeh you should be fine so long as you backup your sd before hand. You can also use the same nexus tool to backup your apps and restore them using the developer tools backup

[Fixed] Black Screen on Boot

Hello.
I just rooted my phone for the first time with Motochopper and flashed the Google Wallet Mod. Everything was working fine until after a while I tried turning my screen on and it wouldn't turn on. I rebooted the phone and the Samsung Logo with the Custom Lock logo appears for a short while, then the screen goes black. After about 20 seconds the blue LED stays constantly lit and slowly fads in and out - after a few minutes the device becomes really hot. The screen stays black and I can't do anything. Is there any way to get my phone back to normal without deleting everything off my phone and restoring the stock ROM?
I have a US AT&T Samsung Galaxy S4 16GB (SGH-I337).
Any help is appreciated,
Thank you.
-Problem fixed.

You have any backups? try restoring one and see if you get the same result. If not, odin back to stock would be your only option.

Unfortunately I don't have any backups. This is my first Android phone, coming from an iPhone, and I'm still getting used to rooting as opposed to jailbreaking. I installed TWRP before I flashed the Google Wallet mod but thought I would be fine until I get an external micro SD card to create the backup on. Is there any way I can access and transfer my photos that are on the device either via Recovery Mode or Download Mode to my computer before I loose everything restoring back to stock?

If you just rebooted thru power menu, try pulling battery--
Did you try manually booting into recovery--

The first time I rebooted, I used some combination of the power and home button because when I tried to turn it on the screen was black. Something must have happened while the device was idle because everything was fine but when I turned it on it wouldn't come on so I rebooted. When it boots, the screen stays black with the blue LED and if I try to reboot, the same thing happens - it's stuck in a loop and the only way to turn it off is to pull the battery out. I can manually boot into recovery, but I have no backups. I've tried doing a Factory Reset in the TWRP, but no dice.

Wow--lesson learned hard way--ALWAYS have backup on phone and pc, including a copy of your sdcard--
That should be at top of every phone forum stickies--
I am not expert on Samsung yet. But, on my HTC phone we would have downloaded a rom to the pc and thru adb pushed it to phone then wiped and flashed it.
It is easy, but you will need to get adb files on your pc or download and install Android ADK. I think if someone has them for this phone you can copy them to pc and put in adb folder and bypass SDK. They are in some of the exploits like motochopper. Matter of fact you could probably extract motochopper and put in your download folder or to desktop and run adb from there. It has all the commands.
Some one else more expert on phone can confirm that and give exact push command to get rom to phone. I can Google it, just haven't used those commands for awhile,
It will be something like putting motochopper extracted folder onto pc. Opening a terminal window and cd'ing to where ever you put it
Then typing adb push rom.zip /sdcard rom.zip
Of course you need to rename rom to "rom.zip" or use the exact name of the rom you put on pc.
That command will have rom.zip on root of sdcard

I pretty much had this happen to my phone -

I am on an iMac and use Android File Transfer. Not sure how they do it on PC as I thought we still can't mount sdcard in Recovery. Maybe Kies if it works for you. But, if you can only get to recovery and no backup, pushing a rom may be the answer. Come morning you'll get more answers. One thing I noticed coming from TMobile HTC to US ATT, not much overnite posts since we are all within 3 hour time zones. With Tmobile, lots of Europe folks.

I was actually able to mount USB Storage via TWRP and use the ADB command adb pull /sdcard/DCIM/Camera to extract the photos off my phone to my computer. Now it's not so bad if I have to restore to default.

Always always backup FIRST before attempting to do anything, that is lesson one period.

Great. Since you are up on adb you can easily push a rom. I will have to try to mount in recovery again. I think android file transfer messes with mounting.

Instead, I used Odin to flash the stock GS4 firmware. Now my phone is working again. Oh and I made a backup this time.
Thank you to all who helped me.

Super. Having not used Odin and on an imac, not sure that was an option in your case. Glad you got it.
