Okay, so my Unlocked Galaxy Nexus keeps bootlooping, but not in the standard way... It turns on, stays on for 15-20 seconds, then crashes. It also might be worth mentioning that the device is rooted. I have gone into recovery mode, wiped the dalvik cache, wiped the cache partition, then attempted to factory reset, although when I do so, I get this message "E: unknown volume for path [/sd-ext]". After I reboot the device all my data is untouched and it keeps bootlooping. I've also tried flashing the factory version via the Nexus Root Toolkit, it seemed to be free of any errors, but again, once I booted the device back up, all the data was still there. One more piece of information that might be useful: when i boot the phone in ODIN mode it says "Downloading... Do not turn off target !!", I'm clueless as to what this is supposed to mean. Any help is appreciated, I've gotten a new device already, but this issue makes me incredibly curious as no repair shops had ever encountered an issue like this one before, and I've not found any threads on the topic.

I brought my Nexus Prime from Korea last month.
A few hours ago I was listening to music on my phone when it rebooted. After that it came back on for roughly 10 seconds before rebooting again.
I uninstalled a game from my phone roughly 30 minutes before this error happened.
I cannot use my phone now, I get a few seconds of use out of it before its stuck in a continuous reboot cycle.
I have tried letting it cool down (it was a hot day), removing the simcard and changing batteries. Not sure what else I can do with only a few seconds of use.
Model number - SHW-M420S
Is anyone able to help me get out of this reboot cycle?
Try to back up important things and do factory reset. Is your phone rooted? CWM recovery installed? If so, before doing factory restore you could try wiping cache/dalvik cache first.

Luckily its still a new phone, so there isn't much on it.
The phone is rooted in that I cannot access it in any way. Even connecting to a computer is useless as its only on for a few seconds before it reboots itself.
CWM recovery isn't installed, will be when the phone is working again though!
Is there a way to wipe the cache/dalvik cache or factory reset while the phone is off?
fastboot will allow you to erase data,userdata, as well as flash a custom recovery like cwm or a full rom.

edit: boot your device with POWER+VOLUP+VOLDOWN into fastboot. search google and/or xda for some fastboot tutorials.
I had this problem awhile back. It was a bum phone with hardware issue. I had to exchange it. Yours may be in the same boat.
I will try a fastboot later today and let you know the outcome, thank you.
If all else fails I'll send it back to Korea for new hardware I guess.
I ran into this problem a while ago. I had to restore the phone to stock using the image from Google. Haven't had a problem since
ok so heres what happened. this morning my phone started behaving weirdly. then it restarted and got stuck in a boot loop. I was running the newest aokp release. after the boot loop i restarted to recovery, i was using the team win one. i wiped cache and dalvik and restarted...still only to boot loop. next i tried factory wiping and reinstalling rom. still same thing, only then i couldnt clear the cache. if i tried it would just reboot.
on lunch break i figured id just odin back to stock. after playing with it a few times i got it to flash the stock back. after it rebooted the first time it went into recovery to clear the caches like it should but there was a red message saying cant locate efs or something. there was about 4 lines in red saying pretty much the same thing. and it said manual mode at the bottom.
ive tried wiping caches and restarting a number of times. I fallowed both the guides from the development section and from the general section. so i currently have the stock ics odined on the phone. it will boot to the rom and start. made it through the upgrading android part then once it gets to the home screen it will sit for a minute then reboot again and just boot loop. i can clear cache and make it boot back up but it just restarts after a few secondds.
please anyone know what to do? this is my second gs2.
Hey guys, my first post on XDA. Alright so straight to the point. My Galaxy Nexus (maguro) has been stuck in boot loop for the past day, and no matter what I've tried, can't seem to fix it.
I have CWM, and I've tried factory resetting through it, I've tried wiping the cache,dalvik cache, data, system and cache partition but I can't seem to get out of the loop, in fact it doesn't seem to delete any data in the first place, I'm still stuck with my notifications popping up every time I get onto the home screen for those rare few seconds.
In the few seconds that I do get available on my home screen, if I try to factory reset the normal way through the system setting, my phone reboots without resetting anything.
So yeah, I'm at a total loss, the last time I had a boot loop a simple factory reset did the trick, but this time literally just don't know what to do.
My phones a Galaxy Nexus, running Paranoid Android 4.4.3 beta 4.0 I believe, and my CWM is 6.0.3 I think
So any of you guys have any suggestions?
EDIT 1: Forgot to mention, every time I try to connect it to my laptop via USB, phone reboots. I don't know how much info this offers, but I'm trying to be as thorough as possible.
Try to flash a factory image. But your EMMC is probably fried..

NOTE: This device is not mine, it belongs to my girlfriend and I am the one troubleshooting for her.
here goes:
Yesterday, while a friend of my girlfriend's was playing with her Galaxy Nexus (my GF's), it suddenly rebooted itself without warning.
From what I understand, Nexus bootloops that are caused by faulty flashing usually loops at the "Google" logo (correct me if I'm wrong). Her's is a different story, her Galaxy Nexus is pure stock, locked bootloader, un-rooted and definitely nothing custom on in; literally pure stock. Instead of looping at the "Google" logo, her GNexus loops at the "X" logo, my assumption is that there is something, maybe a rogue app, that is causing her device to bootloop upon reaching startup phase.
I know this isn't a software/ROM level issue since we were able to get to her lockscreen a few times and then the phone reboots after a few seconds. I've tried wiping cache but didn't work, and she won't let me try wipe data/factory reset because she has a lot of important files on her phone. So odin flashing and wipe data/factory reset is out of the question.
so here are some details that might be of interest:
1.) Her phone is not rooted and is pure stock android 4.1.2
2.) does not have custom recovery
3.) does not have usb debugging enabled (not sure, but I assume it's not enabled)
4.) can still boot to fastboot/recovery/download mode
5.) reboots at the X logo
So the basic troubleshooting methods are out, now I'm thinking of using adb pull to extract files from her phone via adb, but problem is, usb debugging is off! Is there any way of recovering her files at least without booting to the ROM itself so I can flash another version of android on it (via odin)?
I've also read about "safe mode" that boots the device without starting up 3rd party apps, only the core essentials. I'd like to go down that route if possible, but we've tried most of the guides on how to boot into safe mode but to no avail. There was one time though that the device booted up and she managed to: open power menu > hold power off > reboot to safe mode, but nothing happened, it just rebooted only to get stuck at the X again.
I may be overthinking this, so I've turned to XDA for help. I know you guys don't like people asking n00bish queries but I've exhausted everything I can think of and I'd like to try everything before I go down the route where I can possibly do even more damage.
I really need help with this, anyone have any ideas? We'd really appreciate it!
Unlock, flash custom recovery, wipe system, data, cache, dalvik cache and flash 4.3 factory image. Problem solved.
Amazon Warehouse sent the wrong Nexus 7 2013, Wi-Fi only instead of LTE, so am returning it. I'm following Jimmy McGee's video on restoring factory settings,* using NRT 2.0.5. This wasn't rooted, just upgraded from 4.3.0 to 5.1.0 (didn't note the original build number, so chose the last 4.3.0 listed in NRT). Everything seemed to go fine through the Bootloader running (8:35 into the video). After that it reboots, but in doing so it stuck on "Google." I turned the N7 off and restarted into the Bootloader screen again (fastboot mode) and tried to restart from there, but it's never getting to the moving balls. Recovery Mode shows the Android icon with the triangle and exclamation point, and then switches back to "Google."

UPDATE: I got into Recovery Mode and chose Wipe data/factory reset. Showed data wipe complete (but nothing about factory reset), but it still stuck at Google on reboot. Same with Wipe cache partition. I should add that the Nexus is not currently being seen by my computer (Win 8.1), except when in Bootloader mode it's seen by NRM. I ran the whole NRM factory reset process again, but was informed this time that the system is 5.1.1, 5.1.0. Not sure why NRM didn't say anything the first time through (Google had downloaded 5.1.1, but I never ran the install). In any case, it ran the same way again, everything looking fine, but then hanging on Google during the reboot.
Any ideas how to fix this?
