[SOLVED]My Nexus is stuck in a bootloop

So yea im stuck in a bootloop. My phone all of a sudden rebooted itself and it never went past the boot animation. I am able to boot into recovery and fastboot. When i do a factory reset and system restore then flash a the rom all over again it still bootloops. I dont have a nandroid backup cuz they got deleted from my sd car. Is there anyway to flash it to complete stock through recovery or use adb through recovery flash to stock. please any help would be much appreciated.

I used toolkit 5.4 and it worked like a charm Thanks for the advice and assurance buddy, i did panic a bit though. This never happened to me in all my time flashing, well ive gotten bootloops but a quick full wipe and reflash of the rom fixed it, not this time. Thanks again.

Find the yakju Odin file on xda or Google it. Extract and run the exe. Put your phone in download mode (volume down + power) plug it in via USB and wait till it restores your phone. You will have a factory restored 4.0.1 Galaxy Nexus after. Once your phone is restored, you should be prompted for 4.0.2 OTA update.

HELP !! Another Boot Loop thread

I have had my GNex for just over an year now.I have been running CM10.1 stable with AK Kernel. Yesterday, out of the blue, my phone went into a boot loop. I get the Google splash screen, then the Cyanogenmod spinning animation starts , and then boots again. I am able to get into fastboot mode and CWM recovery without any problem. Fastboot commands work just fine.
Things I've tried:
1. Search the forums for solutions.
2. First just wipe cache. Reboot continued
3. Factory reset through CWM .
4. Flashed bigxie's stock 4.2.2 rom through CWM. Now the phone reboots at the Nexus X screen
5. Tried fix permissions through CWM.
6. Tried Lock/Unlock bootloader from mskip's Nexus toolkit.
7. Flashed stock Google image from mskip's Nexus toolkit. Flashed without any errors. But phone still loops.
8. Formatted data,system,cache from CWM and tried stock Google image again. And then again.
At this point, I'm totally out of ideas. Any help would be greatly appreciated.

[Q] Galaxy Nexus bricked after Android 4.3 upgrade

Hi guys!
As soon as Google released the factory images for our GNex I downloaded the yakju one and flashed it. All was running fine.
Then I tried to root with Galaxy Nexus Toolkit option for yakju 4.2.2
SuperSU was installed but said no su binary available.
After searching for a while I saw the Chainfire's root method was doing the job for the Galaxy Nexus with 4.3, and applied it to my Nexus.
I can't remember exactly but I think the first restart was fine but I'm not sure.
Now my Nexus is stuck in a boot loop and it can't pass the boot animation. The phone start and show the Google logo, then most of the times I can see the boot animation but suddenly it restarts and the process start again.
Things I've tried before posting:
- Full wipes
- Installing CM10.1 and Gapps from CWM Recovery.
- Restore a backup from CWM Recovery
- Clean install of factory images (takju and yakju, 4.1, 4.22, 4.3)
- Restoring the factory image with ODIN as said in the HOWTO guide in this forum.
- Factory reset with factory images (tajku and yakju, 4.2.2, 4.3) with Galaxy Nexus Toolkit
- OMAP Flash trying to restore some flash memory issues?
By now, nothing works and I'm starting to think that there might be a hardware problem with my Nexus.
So, what you think? Can anybody help me?
Thanks in advance!

Thank you a lot, I read you in other posts from today and yesterday looking for a solution to my problem.
By now nothing solved it, but I'll keep on trying.
All your help is welcome, thanks!

Even after installing factory image takju jwr66v I'm stuck in the boot loop:
- Google logo -> boot animation -> restart.
- (sometimes) Google logo -> restart.
I've flashed it with flash-all.bat script and manually and nothing.
Any idea?

Yes, I tried.
After 20 or more reboots, it showed the screen:
"Android is upgrading...
Optimizing app XX of XX"
And then, bootloop again.......
So extrange.

For me it's the same, after flashing 4.3. ALWAYS stuck at Google logo, I never even saw a bootanimation. And both TWRP and CWM can't restore a backup, when restoring data they suddenly show FAILED and they stop. Thank you Jellybean 4.3, just to try your laggy, choppy experience I'm now stuck at Google logo.

So sorry to read another case.
In mine I can see the bootanimation most of the times.
I really can't understand how the Nexus can't boot properly even after a full wipe or a factory reset using the official factory images (or after ODIN)
As I told before, I'm starting to think about hardware problems, caused or not by the 4.3 upgrade.

i just wanna make sure.
when you are flashing the factory images. are you also doing a data wipe/factory reset?
what happens if you relock then unlock? are you able to even issue the fastboot oem lock/unlock commands?
also. there has actually been times where i thought my phone was stuck forever in the bootloop. then i just let it sit(full battery) and checked it once in a while to make sure it wasnt getting too hot, and it has fixed itself. i would get worried as heck thinking that i was screwed because all the methods i tried just refused to work(including a nandroid restore with the data error mentioned above) and somehow it fixed itself and finally booted up. then once it was booted fully i went with factory img restores.

Yes, I'm doing a wipe/factory reset before and after flashing stock factory images, and I've tried without doing any wipe and still nothing.
I can use all fastboot commands (lock, unlock included), flash custom recovery images, etc
Now, with CM10.1 without Gapps installed, sometimes the phone can complete a boot and show the lockscreen or even permit me navigate through the launcher but suddenly, it shows some airtfacts in the screen and restarts again.
Thanks!

its sounding more and more like the time i accidentally left mine in a freezer(worked in a kitchen. set it down after using in an industrial freezer that goes -10F !! for over and hour. it just wouldnt boot. after warming up it was as if /data was corrupted. i couldnt do ANYTHING.)
i was pleasantly surprised when it just fixed itself after insane amount of tries of wipes, installs, restores.
good luck! i hope it gets back in working order.
(im also wondering if it might have something to do with the supersu install, as ive read that there has been issues with it and people not being able to get to the symlinked /data things such as the legacy symlink. have you checked to see if there is a "supersu removal" zip you can flash? just in case that helps? or maybe try to fastboot boot the 4.2.2 boot.img? wondering if installing cm10.1 and then fastboot boot the CM stock boot img just in case something isnt installing right with that)

Try fastboot erase commands instead of factory reset in recovery

Maybe this can sounds stupid but, did you check MD5 of the downloaded image? I don't know, just to discard some reasons

OP what computer OS are you trying to do this from? I am wondering if something isnt flashing right due to a windows issue and as others like Sdobron mentioned check the MD5 of the tar.

After reboot everything is slow and jerky, phone unusable!

Guys I have a big problem!
For about a month I have on the galaxy nexus rom slimkat + kernel dfk and until tonight I had not any problems, until this evening the phone has rebooted and the disaster happened, the boot animation was jerky and the phone has put more than 5 minutes to power, however going slow, and even after I have booted the phone is super slow, it's all jerky and unusable.
From recovery I tried to wipe system, but even if the message confirming correct operation, it really does not matter because if I reboot the phone loads the system, even if ever so slow and jerky.
I also tried to use the Nexus root toolkit but nothing, when I try to reflash stock hangs the command "writing system" and does not go forward ... I do not know what else to try.
I also tried using fastboot commands, but nothing changes ... not the operations are successful and the changes are not applied.
Please help me! Thank you very much!

Wipe system, cache, data, dalvik cache and internal.. Then flash stock factory image and then install roms

Wipe from recovery do not work.
I tried to flash from toolkit the stock factory image, but hangs on the command "writing system".
There is another way to flash it??

Yes..you can to flash another recovery with nexus root toolkit. Boot into android and enable usb debugging in dev. options, connect gnex with PC and flash recovery (cwm or twrp or philz, not STOCK) and then wipe..

I've tried, the procedure seems to be successful but the recovery does not really change.
I also tried to flash the stock rom with odin, well after the half-hour procedure is successful, the phone has rebooted but nothing, everything remained as before, with the old rom.
I do not know what to think anymore, I try recovery, toolkit, fastboot and odin but nothing.
I came to doubt that it may be a hardware problem with the internal memory of the phone, do not you?
Thank you!

Try to boot into recovery temporary with nexus root toolkit if you can't to flash..this can help to wipe all and brick gnex

I boot into temporary recovery and i do successfuly all wipe, but when I restarted the system, nothing has changed, loaded the old rom
I do not know what to do!

If you wiped, system can't be rebooted. I really don't have more ideas
Maybe you have problem with hardware.

[Q] Stuck at Google Logo, can only access fastboot

Hi,
there are several threads on this forum dealing with nexus devices that get stuck at the google logo when booting up, however my case is a little different:
I can not even get into recovery.
Here's the symptoms:
The touchscreen became unresponsive. I read that fixing the cache partition helps and it did.
From time to time my device would get stuck at google logo on boot, but i was still able to get into recovery, wipe cache and it would work again. This happened 2-3 times over the course of the last 3 weeks maybe, so i thought its just some minor hangup
2 days ago the device became unresponsive again and i was unable to get into recovery. I have tried several times and once i was lucky to get into recovery (it showd google logo, but when i pressed the power button to turn it off i got into recovery)
now nothing will work. i can get into the bootloader no problem and fastboot is in a working condition
i have tried flashing the factory image using the files provided by google. So far no success
Does anyone know something else to try?
EDIT: aniket0317 suggested using Wugfresh's Root Toolkit which includes a script to unbrick in case of bootloops. That seems to have worked.

Flashing back to stock is a first step, to ensure it's nothing in the software. What do you mean by "So far no success"?

Use Wugfresh's Nexus Root Toolkit. There is a option named Stock Flash+Unroot (Bootloop). The device should be able to get into fastboot mode, though.

This seems to have done it. I have followed the instructions in the toolkit and rebooted the device several times already successfully. The next days will tell whether the touchscreen freezes still happen. But for now, thank you.:good:

Hey,
my Nexus 7 2013 has the same error.
Im stuck in Google screen, only enter in fastboot mode.
Tried Nexus Root Toolkit and other methods but stays the same...
In TWRP, touchscreen doesnt work.
What can i do???
Thanks!

Hey thiago,
I don't really know what to do, but I have the same problem now...
I guess it should be possible to somehow boot clockworkmod recovery from fastboot,
but I'm not sure.
I'll mark this thread not solved again -.-

EDIT 2: Yes it worked, at first. Now the device is stuck in a bootloop again. I can boot into team win recovery, but touch doesn't work there so I can't do anything. Booting CWM from fastboot is also not suceessful.

What do you mean CWM is not successful, that there's no touch response? If all else fails, you can use the non-touch version of CWM, using the side buttons to navigate. But I'd be concerned if screen touches are not being recognized.

CWM dont start. Only twrp. Is there a TWRP non touch version?

There's no non-touch version of TWRP that I know of, since its design is based on touch.
What do you mean by CWM won't start? It just freezes? Did you flash the correct one?

Yes, i used this version for Regular N7 2013, but still frozen in the google screen.

I have the same problem.
Stuck on google logo. It boots Fastboot only. It does not boot system or recovery.
What I have done so far:
Unlocked the bootloader
Flashed preview android L successfully But it did not boot. Then i Installed android 4.4.4. Successfully But still nothing. Then i flashed android 4.3 with the same result. Lastly i flashed TWRP to try and flash a zip, but again it does not go past the google logo. Everything i flash goes successfully or at least there are no errors on the logs. I have used wugs nexus toolkit to flash everything. I can see the bootloader version being changed after flashing different android versions, so i can confirm it is flashing bootloader at least.
My conclusion:
I think there is a hardware problem but I don't know how to troubleshoot what is wrong.
If anyone has any suggestion. It will be much appreciated.

What if you flashed the stock factory recovery/ROM, or is that what you mean by 4.4.4 and 4.3? Don't use a recovery to flash the individual .img files, just run flash-all.bat and see what it does.

Yes. I flashed the factory images using wugs nexus toolkit and ticked the option flash stuck + unroot (bricked or bootlooping) to see if it would work as mentioned by OP. All factory images flash successfully all partitions, but it does not boot recovery or system. I tried different android versions hoping it would make a difference and tried booting recovery after flashing each image (4.4.4 and 4.3). I haven't tried typing the command flash all.bat myself to flash the image as you suggested. I've used the toolkit to make it easier. I'll try flashing stock typing command flash all.bat myself and report.
