Yesterday I had a negative experiance with my GN.
After playing around for somewhile with my GN there were some apps that caused FC's. I decided to reboot the phone. Then the drama began.
I had to reboot one time after another. Sometimes the phone hung the part where you unlock the SIM card at boot and spontaneously rebooted after a while. Sometimes the phone started up and then after 10 seconds a total freeze appeared which I could not ger through. Pulled battery out and in, etc. etc. Tried at least a dozen times. I ended up wiping the cache through fastboot. That brought no solution. Then I performed a factory reset and now I have my GN back.
I am running on Stock 4.0.2 Fast Boot unlocked, rooted and SetCPU with an interactive profile and minimum 350 MHz max 12k. as many have. I had just been playing a while with the GN, but did no nstallations or anything like that. This is the first problem that I encounter with the GN.
Have more people experienced similar behaviour and do they know what caused it (and do they have a solution)? I am afraid that it may occur again and I do not want to do a Factory Reset again ;-)

So since all the other threads revolving around this issue seem to be nothing more than suggestions of things to try rather than trying to determine what the problem is, I wanted to start fresh.
Here's my issue regarding reboots on my Evo (Hw 003). Simply put the phone will reboot (typically under moderate/heavy use, I've not once seen it reboot on it's own, although I can't say it hasn't when I've been asleep).
This issue has persisted regardless of HBoot Version (I've been on 0.76 ENG, 0.97, and 2.10), PRI, Radios or ROM. Trust me, I've tried nearly every combination. It even persists when fully unrooted and returned to stock.
I've obviously tried every type of wipe (both through CW and Amon's Recovery and using Calkulin's WipeAll method in both recoveries) prior to flashing roms and after restart/crashes. I've tried eliminating SD Card issues, and these issues persist regardless of whether the SD card is in or out, or whether it's corrupted or not.
Here's the only things I can definitely say regarding the reboot issue (which I do have to believe is a HW issue, although it may have something to do with the early boot sequence...see my reasoning below).
When the crash occurs, the phone ALWAYS attempts to reboot itself. Very rarely it will do this successfully (but it seems to only be successful in doing so when on customs ROMs, specifically CM7 nightlies, which makes me think that those crash/reboots are unrelated and are actually just software issues with the rom/apps in question and should therefore be disregarded).
If my phone is currently set to S-OFF, the reboots always ends with under 5 seconds on the white HTC Evo screen, then display goes black and I get five vibrates and a flashing green power LED. When this happens and the phone is connected to my laptop via USB, right after the 5 buzzes, I get a Hardware Growl notification that a Qualcomm USB device has been connected.
If the phone is currently set to S-ON, the reboots result in a bootloop that again, shows the white HTC Evo screen for less than 5 seconds, then the screen goes black, phone restarts and starts the loop again. In these cases I don't get the Qualcomm/HW Growl message.
With S-OFF the only surefire way to get a working phone back is to remove the battery for a few minutes (seems like it needs at least 3-4 minutes, which makes me think some form of volatile chip/ram needs to drain to a certain point before working again). I can always get HBOOT/FASTBOOT though, even if I just remove the battery for a second. It feels like I can get into Recovery with the battery removed for less time than it takes to actually boot into the OS, although this may be an inaccurate observation on my behalf.
With S-ON, while removing the battery seems to yield the same results as when the phone is S-OFF, occasionally if I let the bootloop play out, it will eventually hang on the white HTC Evo screen for some time, then restart and boot like normal.
---------Conclusions----------
From what I can tell this whole reboot/crash issue people seems to be having (when it isn't caused by bad flashing or improper use of the phone) can be narrowed down to two areas.
1 - There is an issue with the phone's RAM. This would make sense since there is a difference in the results of removing the battery for a short time or long time when trying to recover from a crash.
2 - It's an issue with the phone's early boot sequence. Perhaps the phone's internal memory (specifically the boot partition or wherever HBOOT/FASTBOOT is stored, not 100% sure where that actually is) has bad sectors or is otherwise corrupt.
I'm leaning towards the RAM being the culprit though, since it seems to be the only thing linking all of the different crash/reboot scenarios. And although I've heard rumblings that it may be a CPU issue, I really doubt this since I can always get into HBOOT/FASTBOOT and because when it crashes and give the 5 buzzes (which some have speculated is a Qualcomm error code for CPU's) it then seems to be communicating on some level through the CPU and USB with my laptop.
While I obviously can't replace the phone's RAM to check this, I just wanted to see what the opinion of those who are a bit more familiar with the phones inner workings than I am have to say about this.
stefpap I have been experiencing the same systems that you describe here. I am currently on the Synergy rom, but I have also experienced this while on myn 2.2 . I have tried multiple reboots/resets and clearing of the sd card except for the rom itself. I want to say that the reboots happen while the GPS is running in maps and navigation. They also seem to happen while watching 15-20 min into a movie.
Have you made any headway on the issue? I also tend to believe that the memory is running away. I have found that the battery becomes a little warm when i remove it for the reset ( I dont know if it has anything to do with this issue)
One last thing, I cant remember this happening when I first received the phone. it also wasnt rooted and had different versions of apps, but who knows.... please let me know if you have found anything about this issue.
Well as an update I uprooted my phone and took it into a repair center, they saw what it was doing (see above) and ordered me a referb. Turns out the main board was causing reboot after getting to hot.

I don't know what's happened lately, but in the past few days my nexus has frozen during completely random tasks. Once while typing a message in google voice, once while browsing the web. It freezes, completely stops responding...nothing at all happens, then the screen turns off. It doesn't even reboot. And I cannot wake it up. I have to do a battery pull.
How can I find out what's causing this?
My issue is similar, but not the same.
My unlocked (but unrooted) GNex randomly turns off during use. I'll be listening to a podcast and browsing XDA, or listening to music and browsing the Market, and without warning, the phone will shut off instantaneously.
I don't need to pull the battery; it turns on normally by holding the power button. I've had absolutely zero problems with this phone, until this issue happened to me several times in the past week.
Not very optimistic about finding a solution. I'm gonna flash CM9 once it's completely stable and pray it wipes the slate clean.
Wow. Didn't see this thread. I posted above with similar problems.
Mine (LTE VZW 4.02) never did this the first week i had it, but since rooting via ODIN, it has randomly rebooted several times, in addition to completely dropping 3G a few times in the past week.
This is with a full stock but rooted/unlocked LTE GNex.
Stock rom and no modifications
I have similar experiences. First fiends complained that Im not at gtalk so either wlan or 3G had some problems. Few days later came random boots and after half a day the phone cant even boot more than few seconds to the bood animation.
After paying 650e for a phone I would like it to work more than 3 weeks. The pending repair.... .. I waited 1.5 months for my Nexus One. It broke almost as fast. How hard it is to make phone that just works?

I had similar freezing when I was stock rooted on 4.0.1. After flashing a custom rom on 4.0.3 more than a month ago, not only have i not had a single freeze but the multitasking button no longer lags (which was my biggest complaint)

I have searched for this issue but couldn't find anything about it...
So I got my GSM Galaxy Nexus from Rogers 10 days ago. It has been working dandy with maybe 1 force close the whole time and no random reboots. I also unlocked the bootloader and installed 4.0.2 (yakju) keeping the radio that came with it intact.
I also installed Google Wallet on it and successfully used it. Other than that, I haven't done any tweaks, and like I said, it has been working perfectly with no problems whatsoever.
Enter today: I woke up this morning and went to check my phone. Instantly like 3 applications force closed (ones that weren't even running in the foreground too). Now for the past 3 hours hours or so, applications force close (some won't even have a chance to run for a second) and the phone reboots randomly. I think it has rebooted around 30 times in the past 3 hours. Sometimes it reboots as soon as it has booted up, sometimes it works for a few minutes before rebooting.
Every time it reboots it shows my old battery stats (I think.. from before I went to sleep), and notifies me of the same emails. I managed to install one app before it did a random reboot once, but after the reboot it was gone. (Think Groundhog Day).
I have no idea how to fix this short of doing a factory reset. Anyone have any ideas as to what may be happening or how to fix it?
Thanks.

Is it doing a full reboot or just a "warm start"?

What's a warm start? It seems to be doing a full reboot.. Screen goes black, then Google logo appears, then the boot animation.
It seems that I cannot do a factory reset.. selecting it in the menu brings me to the android robot on its back with a red exclamation mark, and selecting wipe data from that menu doesn't actually wipe anything even though it says it does.
Try unlocking and relocking your boot loader if you are going to factory reset anyways

It's already unlocked.. You mean locking it and unlocking again? Also, is there any way to batch reinstall all the apps tied to my account? And also, any clue how this issue could have originated? I want to avoid it in the future.
No idea.. all I can think of is an app using all of your memory as that's what causes a force close.. and sure try relocking and unlocking if a normal factory reset won't do it. If you have titanium backup you can use that to batch reinstall but if it is an all causing this issue you should install them one at a time to see of there are any adverse effects.
I don't know if it is an app but that is my best guess.

I hadn't installed any new apps prior to this.. and everything was working fine before, which is why I'm confused as to what could have caused this. Also, not just one app force closes, but like 4 at a time.. usually the Google apps for some reason. I checked the memory and the CPU and it seemed to be running at normal levels.
Have you tried an old-fashioned battery pull?
Haven't had this happen to me, but a pull usually does the trick.
Yep, and it hasn't worked.. Every time the device reboots, it will either reboot again right away, or if i don't touch it, it will idle. Then if I try to do anything, 3 or 4 apps will crash instantly, and then it will freeze and instantly restart.
If I manage to install an app, I can run it, but then it crashes and reboots again with no sign of the app. Deleting apps is also useless as they are back after reboot. Strange issue.
Guys, I really need help.. I finally had time to sit down with my phone and figure out this issue so I decided to just do a wipe. As I wrote previously, I am unable to wipe it from within the OS due to it rebooting when I do, so I decided to re-lock the bootloader.
When I typed "fastboot oem lock", it changed the lock state on my phone to locked.. as I was expecting.. however, when I rebooted the bootloader, it was unlocked again. WTF? Now I am trying to flash stock 4.0.2 to it again (which it was already), but it's been stuck on "writing 'system' ..." for half hour
Could the flash memory be corrupted somehow?
Ok, I have deduced that it is most likely corrupted flash memory.. I didn't even know that could happen, especially in 10 days.. I guess that's good ol' "Made in China" at work. Still, am I the only one who has had their flash memory fail on them?
Crossing my fingers that Rogers will replace my Galaxy Nexus even though it's rooted and bootloader unlocked :/
Hey stenzor,
I am facing same problem of rebooting...
But I haven't flashed it to yakju.
Did rogers replaced your?
Hey Guys, I have been beating my head against a brick wall trying to fix my phone.
Yesterday I was on a call with someone and suddenly I lost service (not uncommon for where I was since I have weak service there), but this time the phone was frozen. The dialer screen was on but was frozen. My phone would not react to anything. So naturally I pulled the battery and rebooted the phone. The phone started up as normally it would but then after 5 minutes of the phone running it froze again. During those five minutes I never received any cell signal.
The most recent "work" I had done on my phone was change the kernel to the AK Kernel on the guide here. This was done 3 days before anything started happening. I tried a new kernel because ever since upgrading to Paranoid 3.0 my phone was acting slow and occasionally I would get a screen of death typically about once a day. The 3 days that I had the new kernel, everything was working great (phone was faster, responsive and no SOD).
I tried restoring a nandroid before upgrading the kernel and it made no difference. Ever since the first time my phone down freezes after 3-5 mins after booting up. Nothing that I have tried has fixed the issue.
I have done a clean install, tried locking and re-rooting, tried a different kernel. All to no avail. Please help I am thinking there is something seriously wrong and may need to take it back to verizon. I am trying to restore my device to stock but am unable to do so. I have been using this guide: Restore to Stock. Any suggestions to make it "clean" enough to get verizon to replace it?
I'm going through withdrawals, please help!
Could not fix it, so I contacted tech support and explained everything that I did to try to fix and they just sent me a warranty replacement. I hope that it was a device error and not something that was caused by other ROMs or Kernels.
So I've had my GS3 since launch, about 14 months. Up until Monday, everything was working fine and I had been through a dozen ROMS. Sometimes things would get buggy, I'd flash a new ROM and it would all be great again.
On Tuesday I noticed that when I'd go to use my phone it would not wake up and need a hard reset. As I went through my day I noticed it would randomly freeze to black while being used and require a hard reset to get going again. It probably went through 20 random resets throughout the day until I had a chance to flash a ROM in the evening, thinking everything would be fine.
Flashed the new ROM, noticed almost immediately the freezes were still going on, tried searching various forums for a fix and couldn't find anything that sounded like this problem. I did check through the Ultimate GS3 freezing thread and Ultimate GS3 Sudden Death threads, but neither seemed to have the same problem. Finally I decided to try the dummy file generator described in the freezing thread and after a while it gave a FC. I tried to run it again and it would not run properly, I cleared the data/cache for the program and was trying to try again when the phone froze for the last time.
It is now bricked, it will not hard reset, respond to battery pulls, respond when charging, boot to recovery, nothing. Can't be detected when plugged in to a computer and I will be taking it in today to see if it can be repaired out of warranty. I doubt anyone here can help with fixing the phone, I just thought I should post this so other people might find it if they suffer the same symptoms and can share similar experiences.
