[Q] serious nexus 7 boot loop problem - Nexus 7 Q&A, Help & Troubleshooting

My nexus 7 has a serious bootloop problem.
i have been researching threads on fixing it and watched many a video and nothing seems to work.
when i boot up i will get google logo and nothing after that.
i have gone into the bootloader and gone into recovery mode and done a factory reset multiple times with no results.
connected to computer and run both NRT and nexus toolkit and tried multiple options.
flashing a new rom wont work because wont boot up and let me turn on usb debugging.
my last cahnce would be to try to get it replaced but it was a gift so do they fix those?
please help i think im going crazy!

What did you do to erase your ROM?

Your rom has been erased, as your device has no system to boot into. Your must have formatted your system. Just flash a rom and you should be fine. If needs be push the zip to your device through adb if you don't have a rom stored in your device, or if the current one is corrupted (which may be why it's not booting), and always check your md5.

All you need to do is flash the factory images through fastboot, or a custom ROM through recovery. There is nothing stopping you from taking either of those actions.

thankyou
i think the problem is actually my computer so i will try it on another one. thanks for the help this is all new to me

i tried to push files with nexus root toolkit but i cant without powering on and allowing usb debbugging, is there anything i am missing? or is there another way to do it?

Yes and USB debugging is not needed.

You can adb push files while in recovery. You need to choose the option in recovery first though.

Help me please

So I've been messing around with android phones for a while now and I'm stuck. I was on the oxygen 2.1.6 Rom then decided to make a back up. However instead of going into CWR it just went into fast boot. When I go into recovery it just says fast boot mode no reboot or recovery img. I tried to odin back to stock like I usually do but adb wont recognize my device like it usually does. Please don't tell me I'm bricked and that I messed up bad. Any help would be appreciated. Thanks in advance.
I tried reinstalling drivers etc etc. Somebody help me lol

It sounds like you flashed a bad recovery. Download a new recovery , boot into fastboot, and
Code:
fastboot flash recovery yourrecoveryfile.img
adb wont recognize my device so how do I flash a new recovery

Adb only works when the phone is booted normally, provided usb debugging is on.
Use fastboot. If you want to make sure it's working, boot into fastboot mode and
Code:
fastboot devices
If it's working, you will see your serial number.
If the other options can't help you get your problem solved try Odin.
www.samfirmware.com
get the right files for your device and Odin program itself. There are tutorials on here how to use it.
sorry I was being an idiot. I tried fastboot and it showed nothing connected. When I flashed a recovery it just hung waiting for device. I have all the drivers loaded on the computer but my device is still unknown and wont be recognized. I have all the odin files and I have used odin before. This sucks
btw appreciate the help guys

Try installing pdanet, that will install all the drivers you need for fastboot and Odin.

my one click works on both versions, as all it does it just gets you root. if you want cwm then use rom manager afterwards.
but for his problem no it relies on adb and fastboot

Maybe not, but it does include some handy files. ;-)
Download and unzip Shabby's OneClickRoot
Install pdanet. (See the readme for which one.)
Reboot your computer.
Then try using his version of fastboot.
I'm assuming you are in fastboot mode (it will say so) and that you're using the usb cable that came with the phone.
I will give it a go now I do have PDA installed too

In Recovery, wiped probably too much - no ROM

Like the title says.
I'm in recovery, I wiped it all (unfortunately even the ROM as zip I put on it) and now I don't have no ROM on it and no zip to flash a ROM.
Thought this was no problem, knowing from smartphone recoveries to mount sdcard and copying the file on it. But Nexus 7, well, has no sdcard.
What can I do?
As it is now, I don't have nothing on it and rebooting it wouldn't lead to anything useful.
I need help.
What can I do?
Thanks in advance.

If you have Android SDK installed, you can use adb push to push the zip file to your internal storage. Put the ROM zip file in your Android SDK - Platform Tools folder on your computer, reboot the N7 into Recovery (connected to computer of course!), open Command Prompt window and change directories to where ever you keep your Android SDK (for me, it's: cd sdk/platform-tools). Then type:
Code:
adb push <name of ROM zip file> /sdcard
Wait, and after about 20 - 60 seconds it'll complete, then you can flash the ROM. It'll be on the root of your internal sdcard (/sdcard).
Sounds difficult for a bloody rookie like me - is there really no easier way? Like transfering via recovery by just telling recovery to mound internal-sd so that it'll pop up on my pc? (know that from CWM and 4Ext on my smartphone)
Or could you explain the steps so that even the bloodiest rookie of them all could understand it properly :-/
aaaw **** -.-
by the way, device is still in recovery

TWRP as well. Just unlocked, rooted and flashed recovery and now I wanted to have a custom rom.
I tried to mount data and what else there was in "advanced" - my PC doesn't show me anything
Edit: not in advanced, it's the point "mount"
Restock and reroot.You can use Wugfresh toolkit for this. You just install the toolkit and if you can boot in bootloader mode you're saved. That's what I did and it solved my problem.

How'd you root/unlock, toolkit of some type?
Using the adb command mentioned is the only way that I know of to push a file to your N7. It's not as difficult to do as it sounds.

Yeah that would work, as long as you don't re-lock via fastboot. That's what probably wiped out your sdcard, was the fastboot unlock of your device, as it wipes your sdcard.

Is it important which current status I choose?
There are 2 to be chosen: Soft-Bricked/Bootloop and Device is on/Normal
If "Device is on" means, that it's turned on, then this'll be my choice, right?

This ain't even my device :-/

No, wiping of my /sdcard was all my fault. I guess I have to take all credit for that
Well downloading the Stock with the toolkit takes quite some time...

I've never used any of the toolkits out there, I've done it using adb/fastboot commands in a Command Prompt window.

Toolkits are probably the easiest way - and it was pretty easy - who could expect me to wipe the zip, I just moved to the storage before flashing it?...

I desperately hope to have the same luck...will the bootloader still be unlocked after that procedure? I understand that root definetely is gone, but that shouldn't be a problem at all.

It will remain unlocked until/unless you run the fastboot command: fastboot oem lock
If you don't run this, it will remain unlocked.
Whoaaaa I could scream!
Now that I downloaded the right one and try to flash it through the toolkit, it tells me, that there's no adb to be found. He doesn't recognize the device in bootloader.
What should I do?
OH THANK GOD! Tried it via recovery, he found it and restarted into bootloader
First of all: thank you so much guys - I was really shocked, but it all worked out
One more question before I make the same mistake again. Where should I put the zip which I wanna flash? When I have it connected to the pc, it shows me a portable device where the folders of the internal storage are (like Alarms, Android, DCIM, Download etc pp) - that's where I put the ZIP before.
Shall I keep it there?
And another question: what should I wipe in order to get it done properly?
Edit: Figured it out - got me CWM, much more familiar with that one
but thanks again for all your help guys

[SOLVED] Unbrick Nexus 7?

Hey everybody,
Yesterday I tried flashing a theme to SmoothRom and got caught in a bootloop. In a panic, I accidentally factory wiped my sd card and lost my roms so now I can't flash another rom to my Nexus 7. I've tried adb pushing a rom to the sd card, but my Nexus 7 is not being recognized in adb devices. I've tried everything to my knowledge but I still cannot get anything to work, even tried working on Mac and PC computers and my Nexus won't show up in adb.
I'm ready to count my losses as it is my fault, but I figured you guys could help out. I love my Nexus so if you guys know anything I could do I'd greatly appreciate it. Thanks.

Ok guys, I spent all last night trying to get this to work, and I'm still having problems. I tried adding the line to the driver inf file but nothing worked. I tried adding the PDANet drivers, but the Nexus of course is not showing up. I know that my Nexus is not doomed it's just something I'm not doing right, not gonna give up I'll keep at it. Thanks for the help guys, if anything have any suggestions let me know!
Sounds like you should find out if CWM touch can mount a USB flash thumbdrive via an OTG cable. You can avoid driver problems that way (as long as it works). The filesystem formatting of the USB drive with the highest probability of success will be a FAT format.
good luck

If fastboot is really dead, then you're out of luck. Have you tried running fastboot commands, however, after trying to boot into fastboot? Sometimes the underlying software will run correctly, even if the screen is nonresponsive.

So I assume this means my only hope is to replace the motherboard which houses the memory. Is that a good assumption?
HELP!
so i had the same thing happen to me. I had access to recovery still but instead of re flashing i tried to use nexus root toolkit to factory reset. somehow fastboot failed halfway through and now recovery is gone with everything else. The only thing i can get into is the bootloader mode....
My device is still listed as a fastboot device, but when i try to re-run the flash to stock i get this: (see attached picture)
Please help, I honestly have been working on this for days, but i simply do not know enough to fix it!

I'm having a similar problem. Present state of the device is that my N7 boots into the bootloader and then to the custom recovery. I've accidently erased the OS.
Can you tell me how you managed to unbrick via OTG. Should I move the factory image to usb flash drive and then mount it via OTG and then try to flash it via recovery???

Greed lead to Brick!

Hey guys
I thought I'd just let you all know that my ambition to get 4.3 and lack of knowledge, led to my phone getting bricked today. I'm so devastated. I was following efrant's guide and flashed everything correctly and then as usual I lost half my storage and I followed the other guide to restoring the lost storage, once again i followed everything but i didn't get the storage back, then i did some cmd commands like the guide did. Next thing you know I may have done something wrong and I was at the bootloader screen and I couldn't reboot or go to recovery. Read and read nothing helped, called Google and they couldn't help me. I am now getting a replacement. SO there you go guys, just the greed of getting 4.3 caused me to brick my phone as well as my lack of knowledge I guess. Can't complain. Thought I'd share this with you all.

In this particular situation i wont recommend you using a toolkit. Is much esier with a good guide if it fails with the toolkit (btw while i flashed 4.3 factory image the cmd told me also about "missing recovery and system.sig" but now ive got a fully working 4.3 ROM on my N4.
You can do it via ADB. You just setup ADB on your computer. And put all the files from the factory image in the "platform-tools" adb folder. If your phone is in the bootloader menu and its recognized by your computer you just run a file that is called "flash-all.bat" and it should flash the 4.2/4.3 image on your phone. Thats how i did it a few hours ago.
Have a look at this guide: http://forum.xda-developers.com/showthread.php?t=1907796
But remember all the files in this guide are for the Nexus 7 so use the N4 factory images and the proper commands for your device (i mean the last step of this guide which shows various commands. you shouldnt use them becuz they are for the N7 and the proper commands for the N4 are written in the "flash-all.sh" use those commands or use the "flash-all.bat" which is included in the 4.3 factory image [i dont know if its included in the 4.2. f.i.]. All those files have to be in the "platform-tools" folder in order to let the .batch file do its job.
I hope u understood what i wrote. If not let me know.

I have also a phone that is dead after the upgrade. It was just "looping" on the "Updating Apps" screen, so I turned it off, now it won't start. When the "Nexus X" apperas, it just loops on this screen and nothing happens...
I would very much like to keep pictures and texts before resetting the phone! Can I do that in any way??

I can see my phone listet under "Advanced Utility, but I cannot seem to pull the files from my phone!
I am getting really frustrated here now!
Anyone??

I have also a phone that is dead after the upgrade. It was just "looping" on the "Updating Apps" screen, so I turned it off, now it won't start. When the "Nexus X" apperas, it just loops on this screen and nothing happens...
I would very much like to keep pictures and texts before resetting the phone! Can I do that in any way??

Flash ClockworkMod or TWRP and using one of them wipe cache, dalvik cache and data (not storage). Apps and settings will be gone, but your music and pictures will still be there.

This sounds GREAT! Where can I download them! And, will my texts be gone?? (That is not the worst thing, still annoying...)

Oh well you should look in one of those threads on how to root and so on, flashing a recovery using a toolkit should also work. Texts will be gone.
Or from this thread: http://forum.xda-developers.com/showthread.php?t=2010312
Note that some users indicate that they can't get past the X on boot. If this happens to you, reboot into the bootloader and select recovery. Then, when you see the Android with the red exclamation mark, hold power and press volume up to take you to the menu. Wipe cache. If that still doesn't work, boot back into recovery and do a factory reset.

But at some point you'd need a custom recovery anyway.

Enable USB Debugging in Recovery Nexus 4

So I managed to break the digitiser on my Nexus 4 last weekend. I have most things off it anyway but there are a couple of apps I need to run to get the data I need. I would like to be able to use android screencast to run the couple of apps or use it to set up my bluetooth mouse so I can use that as the screen itself still views fine. However, I need to enable USB Debugging in regular operation.
My phone is rooted, has CWM as the recovery and I have the ADB platform tools downloaded to my mac. This for a Nexus 7 is the closest I have come to an answer of how to do it. However, I can't find these files so I guess they are somewhere else to change these settings?
Any help would be much appreciated, thanks!
If you have cwm, not into recovery and use adb to pull files you want off your device

I can't seem to find build.prop to be able to edit it. I can find default.prop but when I do adb pull /system/build.prop it doesn't work just says 'does not exist'.

In your recovery, I use twrp, mount system. It should work then.

Works! Brilliant thanks! Hopefully the rest of this works!
So I have managed to Brick my phone into a boot loop of the cyanogenmod startup symbol. What can I do now?
Can someone confirm what the file permissions should be for settings.db and build.prop?

Permissions should be rw-r-r. There's always the factory image to flash. You're not bricked!

OK so I'm stuck how do I flash a factory image then? And I can't wipe my data or else the exercise is moot. Is there a way I can flash an image with the USB Debugging I require enabled? That would make my life much much simpler!

This going to get some what experimental but it won't wipe your date. I assume your bootloader is unlocked Just flashing the factory image will wipe your data but.... Download the factory image and extract it using winrar or 7-zip. Inside is a zip file, extract that too. You should find a system.img file in there. Flash that in fastboot
fastboot flash system system.img
Hopefully that'll get you past the boot loop
Edit, I'd forgotten that I made this. It'll get you up and running too. http://forum.xda-developers.com/showthread.php?p=533289

Thanks a lot, I have now successfully unbricked my phone, enabled usb debugging and through a series of key strokes turned on bluetooth and connected my mouse. However, somewhere in the process I appear to have lost all my app data which was the points of trying to get in there in the first place. What could have done this? All my data e.g. photos is there but my SMS are gone!

You most likely wiped the data partition while trying to fix the bootloop.
Would the data partition not be where everything else is stored?

Is this image modified so that USB debugging is ENabled?
Background: I'm in the same situation as OP. Broken screen/digitizer, USB debugging is DISabled, unlocked, rooted, CWM recovery. I need to ENable USB debugging, otherwise I just keep getting told "error: device offline".

If you boot into recovery and then type adb devices is it still offline? It shouldn't be. You can recovery data while in recovery if that's what you're trying to do

Yes, when I attempt to run adb while in recovery I still get told that the device is offline.
Not sure what the best solution is. I was thinking about trying to flash a modified factory image that is already set up to have USB Debugging Enabled because I can probably flash that without wiping data. However, I don't know if such images exist or, if necessary, how to make my own.
Clearly the OP got around it but I can't seem to be able to and I'm not sure what to do.

I would start by flashing a twrp recovery in your current cwm recovery. I.know you don't need usb debugging checked in trwp.

Well I'll start there and keep you posted. Thanks!
I was able to get TWRP running as my recovery. When I run adb, my device appears as "recovery", however, I'm not able to access the "build.prop" file to edit it so I can ENable USB Debugging. I think this is because I'm not able to remount "system" as read/write. Not sure what my issue is, but when I run adb root, it claims to be already in root, however when I run su in adb shell, it claims it can't find su. Any ideas?
