Hi guys,
I've got a big problem with my Gnex. I was running AOSPAL Paranoid SaberDroid ROM with Dirty V kernel and Nephilim's settings. Just the read ahead buffer was set as default so it was 512 I think. I think I just forgot to change it. Everything was ok and then I changed RAB to this value about 4000 (max). I started antutu benchmark and while it was running the phone restarted and got into boot loop. I don't know if it was the reason of the issue, but I wanted to tell you all the circumstances. When I tried to turn it on the Google logo appeared and then the system loading animation started, after about 3-5 seconds it restarted and so over and over again. I was able to enter recovery mode, so I wiped cache and dalvik cache. Nothing changed. I flashed Dirty V kernel again, thinking that settings would turn back to default, but it also didn't change anything. I flashed franco kernel, and also nothing happened. I returned nandroid backup but it also didn't help with this boot loop. Then I wiped cache, dalvik cache, system, data and clean flashed SaberDroid ROM with stock kernel and PA gapps. Nothing. I plugged my phone to computer and flashed Google factory image using WugFresh Toolkit, so it wiped everything unrooted my phone and flashed stock clean 4.1.2 android and everything. I thought that will solve my problem, but also it didn't help. Nexus is still in boot loop - it keeps restarting when there is nexus logo animation. I was scared at that moment. I forgot to mention, that I could get to fastboot mode, recovery and the battery logo was showing correctly when phone was plugged to charger. Then I locked the bootloader so it is completly stock right now, it just doesn't turn on...
I read the topic about omap flashing, but as I understand it is for those devices, which can not turn into fastboot mode (and mine does) and then the solution is to flash google factory image, what I did... When phone is turned off and plugged to computer the device menager shows for 2 secs omap4440, and when it is in fastboot mode and plugged to comp it shows normally as Android Phone (Google Galaxy Nexus BootLoader Interface, because I had drivers installed to use the Toolkit.
It is all what I could do and I don't know what else could be done to ressurect my loved Gnex .
Do You guys know what's going on?
Please help me.
I think I have read somewhere in the Dirty V thread that some bug in the kernel was causing the Google logo boot loop. Have you tried using 0sm0sis' Emergency Kernel Cleaning Script listed in his signature? I remember him telling someone to use that script in the kernel thread.
osm0sis's zip only restores kernel tweaks and settings to default. I didn't try it, but now I don't have to, because I don't have any custom kernel right now. My phone is pure stock.
Yesterday I tried omap flashing, and it run properly, but also didn't change anything. I also flashed Google factory image again after omap flashing.
Any other tips? It doesn't look optimistic ;/. Maybe it's hardware? But I thought reboot loops are connected to software and it is soft brick, which can be repaired.

Hi All,
Got a problem with my HOX. Rooted, and was running Franco kernel and PKMN ROM. Had a few issues so flashed back to stock kernel, wiped and reinstalled ROM.
Now I've got a problem; boots up, get a sense lock screen, then when I unlock I just get a white screen with HTC logo on that doesn't go away.
Help!
I've reflashed stock boot.img in fastboot, I've done a fastboot erase cache and still have same issue.
EDIT:
Well, got it to boot. Going thru setup now and it's INCREDIBLY SLOW. It's like it's underclocked to 100mhz or something. It's completely unusable - hitting "Next" in the Android setup menu takes 30 secs to process etc... This is kind of what was starting to happen before I wiped and reflashed - could it be I have corrupt storage or something?

Did you remember to install kernel modules AFTER you installed your ROM? Roms come with their own kernels and the kernel modules are already installed under /system/lib. So unless you flash the kernel modules after the ROM, ROMs kernel modules get installed instead.
Yes, I did. Got it working now though - not sure what it was but mounted USB storage and got windows to scan the storage - then re-downloaded the ROM and flashed again. Weird....!
Hello!
Today, my bro - gnex succesfully waked me up with a new alarm sound (a really weird loop of a Timely sound)... It froze in the "snooze" screen in Timely, and it didn't do anything so I removed the battery and then I turned it on.. It passed the Google logo, but the boot animation never appeared... It didn't reboot (no boot loop), and it got quite hot in the area next to the camera... Now it doesn't start. I can get into fastboot and recovery (Twrp)
It's been like a week since I got it into ParanoidAndroid 4.3 (3.99v), and since, it rebooted a couple of times, don't know if it has something to do with the Rom or the Kernel or if it's relevant...
My gnex is rooted and unlocked (obviously), with PA 3.99 (the latest 4.3?) and franco kernel (r391 nightly).
- First, I wiped cache\dalvik - No change
- Then I did a full wipe - No change
- Tried to install stock 4.3 with the Toolkit (yep, I know that's not the best way... won't do it again) - didn't worked (It looked like it succesfully installed radio and bootloader but then an error stops everything)
I always thought I was such a badass installing things to my unbrickable gnexus, now I'm too scared to do anything else to it without any help...
I'm from Costa Rica, please excuse my English
Any help would be much appreciated!!
EDIT: Managed to install stock again, 4.3, stock recovery and radios... Got halfway of the boot animation but then boot-loop... Went to stock recovery and wiped cache, no change... Re-flashed stock android, no change... Re-locked and unlocked the bootloader so it would wipe everything... Sadly no change...

How did you flash stock? With fastboot via the flash-all.bat?

Hello to all
I have Samsung Galaxy Nexus 4.2.1 stock and unlocked.
It worked perfectly to two years! From yesterday i have problem with it! My GN won't boot anymore, I can see just google and X (nexus) logo after that GN restart itself! This is repeated without stopping until I put out battery.
I have tried to clear cache, wipe data/factory reset in Recovery Mode but problem has continued!
I have unlocked bootloader and update to android 4.3 stock (non rooted) through ADB (google SDK), updated successfully but when phone has reboot problem has continued, GN restart non-stop!
In Fastboot mode/Recovery Mode phone it never restarted! I have left in this mode with hours to try if restarted but no It works without any problems in this mode! It restart only when phone boot up!
Can this problem to be hardware failure or not?!
Can anyone help me? What can i do to boot my GN again?
I hope in your your support

Don't panic, this problem is called bootloop and it's normal. Just download factory images from here and flash them by using this awesome guide by efrant!!
Also bookmark this link for future reference.
http://forum.xda-developers.com/showthread.php?t=1812959
started having the same problem yesterday after 6 months of stability on a custom 4.3 rom.
oem lock then unlock to format, nothing, tried various methods of flashing back to stock via ADB with mixed results, normally more boot looping with it occasionally booting into a rom for ~5 seconds. so SOMETHING is working.
I tried Efrant's method about an hour ago, but its been sitting at the google logo since, I'm at a lost, I'm no stranger to boot loops when installing borked roms but this is the strangest problem I have ever had with an android device.
should I just chock it up to hardware failure?
Mostly yours USERDATA partition is corrupted.
Use FASTBOOT to reflash the USERDATA IMG and it should do the trick.
Sent from my Galaxy Nexus using xda app-developers app
did a total stock reflash again, got to the setup screen before it rebooted after ~15 seconds, bootlooping again. flashed the userdata img with a few different ones.
I'm trying to read my logcat but when I run the ADB command in clockwork It finds nothing.
I've done all steps by this awesome guide by efrant! But same problem here
I've tried to install 4.2.2 stock, 4.3 stock, all comands works but in the end when i press fastboot reboot my nexus it's in bootloop again restart restart and restart
Any other solutions :crying::crying::crying:
I've waited about 30 minutes after restarting non-stop, my GN boot to system i saw home screen of android but after 5 sec restarted again :crying:
I'm getting into my system once every 10 or so reboots. managed to turn off wifi in case that was the problem but still boot looping. I'm inclined to think it might be hardware related as I started having trouble in the middle of a text after several months of rom stability.
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.
The Gnex became very slow and there were apps and processes constantly crashing.
Did a factory reset, and the phone got bricked. The screen was just black, it didn't show a sign of life, not even the google logo.
Then I tried to unbrick it with OMAP flash or something, then it booted, showed the google logo, and then the nexus logo.
Then it crashed and rebooted.
I tried reflashing the stock rom using odin.
That didn't do a thing.
Next, I installed TWRP recovery and installed Cyanogenmod and Gapps.
And its still in bootloop.
I don't know what to do now, please help me!!
Is it still fixable??
Thanks in advance

"Did a factory reset, and the phone got bricked. The screen was just black, it didn't show a sign of life, not even the google logo." - Why did you think it was "bricked"? Did the battery die? Also, why did you use OMAPflash before trying to recover the device with fastboot/factory images (or even odin)?
That said...
Are you 100% sure it flashed TWRP? Did you wipe data/factory reset before flashing CM/Gapps?
Anyways... boot to fastboot (device turned off, hold down both vol keys+power until you see the android flying, big "START" letters at the top, small letters on the lower left corner), then flash factory images. Don't use any toolkits, learn fastboot if you have too.
Wel,I thought the phone was bricked because it wouldn't boot up properly. I tried omap flash because it was the first thing I found about fixing a bricked Samsung. I know the bith volume Keys + power but the phone wouldn't do anything. It didn't even boot in fastboot.
