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
I have a stock GN, not rooted yet. Today my phone automatically shut off and now it starts back up, google logo shows up and all those colors come on for couple of seconds and then the phone reboots itself.
I can press both volume up+volume down + power button and get into a menu which gives me the options of Start, Restart bootloader, recovery mode, and power off. I choose recovery mode but then it goes on to an android sign with exclamation mark. After that I can't seem to get anywhere. I have tried volume up +power, volume down+power, and volume up+down+power but nothing seems to work. It just keeps on rebooting it self.
Any solutions to this problem??
There are two possibilities:
1) Software problem. Since you were stock, this is unlikely.
2) Hardware problem. This is more likely, in my opinion.
If you want to eliminate 1) as a possibility, you can try this:
1. Download the GNex Toolkit here
2. Install it & get the drivers working on your computer (if you haven't already)
3. Unlock the bootloader by selecting Option 3 (it'll wipe your phone)
4. Flash factory stock rom by selecting option 8
5. Try it. If it works, congratulations. (if you want to re-lock your bootloader, use option 11)
If this doesn't work, relock your bootloader and send it in for warrantee. (most likely a hardware problem)

So, I did the above method and after flashing the factory stock rom it won't start up anymore. It doesn't respond to anything at all. It seems I've bricked it
Is there any way to unrbick it now? I'm assuming I can't send it in for warranty either now if it's semi bricked. Unless it's been completely bricked which means there is still a chance of getting a replacement phone.
I have the same prob on rooted SGN
This morning I switched off the airplane mode to be available, system crashed and restarted. And then still the same again - booting / android logo / restart again.. /./. I am using Android Revolution HD 2.1.5, for last month with no problems.
I tried to boot into recovery, then wipe the cache and reflash rom and radio from sd, it is still the same. I can see all the files on my int. sd with no probs.
Please help.
I'm thinking it might be a hardware issue, but I'll wait for another member's opinion before confirming.
Solved!!!
That's what I thought - HW prob, but it seems that luck is on my side, I hope. It helped to get back on stock but with total deletion including int partition
Anyway thanks for support.

Was your phone rooted or bootloader unlocked before the problem occurred?
Anyways I've sent in my phone for warranty, hopefully samsung will fix it.
So my phone company called me today and apparently Samsung told them that it's corrosion(?) problem. When I asked exactly what does that mean they said it's moisture damage or physical damage that probably caused it. But I'm confused how could my phone possibly get moisture damage inside an otter box. I know how delegate these devices are and I know how to take care of them.
Anyhow it'll be $90 to fix it. I had no other option so I asked them to go ahead with the repairs. So frustrated with Samsung to be honest. I never dropped my phone once, never had any water damage, phone was always inside the defender case. And I still have to pay them for fixing my phone even though it's not my fault.
That's quite worrying, I just started having boot loop problems today. I've had the phone since Feb 29th and not had a problem with it yet, but today it started boot looping. I went into recovery and did a factory reset, was alright for a couple of hours then it crashed, started bootlooping again. Running stock 4.0.2 unrooted, I'm wondering if flashing 4.0.4 might help.
I'm in the same boat.... unrooting stock 4.0.1 firmware - canadian version from Negri.
April 23rd my phone crashed and started boot looping. Google logo - reboot - Google logo - reboot
Factory reset worked. I installed less apps than I had before figuring perhaps an app was corrupting something.
Yesterday - it happened again. Phone crashed. Boot loop. Factory Reset worked. Installed even fewer apps.
We'll see what happens this time around. I am hoping it is just a software thing. Hoping 4.0.4 gets pushed soon too.....
I've been having the same issue, plus sometimes my home screen it would lock up and wouldn't let me do anything, so I did a battery pull and it would boot loop for a half hour.
After the 3rd time I just took it to my Verizon wireless store, and showed them the situation and they couldn't figure it out, so their sending me a replacement, which I'm not looking forward too, don't want a semi-used phone....

Rebooting Issue Solved.
I was also a troubled Samsung Galaxy Nexus user and my phone kept restarting more than half a dozen times everyday. Most of the times when I switched between two or more applications, or when it was simply idle on my desk.
However, I found a solution (at least in my case). All I did was root my phone, install cwm recovery, and flash a custom rom after wiping cache and factory resetting the phone, It's been about 5 to 6 hours now since I flashed the custom rom and I haven't had a single reboot or hang since.
Others who face this problem, please give it a shot, who knows? You might save your Galaxy Nexus instead of sending it back to get a replacement or spend some money on it for repairs which aren't even required in the first place.
I also had this problem unrooted. I had to give it to Samsung for the warranty
Swyped on my Galaxy Nexus running AOKP with Trinity Kernel, overclocked to 1.4GHz
I got my nexus yesterday, almost immediately after first start it start to install JB from OTA.
I did buy 2000mAh samsung original battery and started straight with it. not even testing with 1750mAh bat.
after installing JB and needed softwares, it started to randomly reboot.
it rebooted even it was just in my pocket.
sometimes when I did do something, display freezed and after about 5sec it rebooted.
Now I did changed to original 1750mAh, and it havent boot at all couple hours, even I did play angrybirds space.
I wont dare to root it before I am very sure problem is with 2000mah battery.

I could be wrong, but have you tried to clean the pin on the battery? Seems like battery and the phone isn't contracting too well
Swyped on my Galaxy Nexus running AOKP with Franco Kernel, overclocked to 1.4GHz
Little update, phone did continue rebooting with original 1750mAh battery also.
I did also reset with recovery mode, and after that it did also reboot one time.
like it uses all memory/cpu and when nothing to do reboot (like windows )
I also did flash stock rom with toolkit but no help.
I will test rooting phone and flash another rom, or is it useless ?
after using couple days, not yet rooted.
Phone works and wont reboot even in heavy stress. but sometimes it just reboots by own not a single program in task list.
might reboot right after previous reboot or take hours to reboot.
stupid phone
I have been done some research.
I did one more time reflash google stock with rootkit, and forgot lock phone, it was almost 3 hours by own in wifi, no reboots at all.
when I noticed that I forgot to lock it I rooted whole phone and installed paranoid android 2.13 with CWM.
Now Ive been using 2 hours without any reboot, installing software, setting things up and using apps.
I dont understand at all:silly:
edit: noup, yesterday evening one almost reboot, paranoid android did reset itself but didnt even reset uptime. so I didnt count that normal reboot.
but after wake up this morning, it did reboot once when I put in my pocket, another just lying on table, once activating bluetooth in my car.
going to send it back to seller.
I have a similar issue, although not quite the same. Last night my phone started boot looping - it managed to boot up to the lock screen, and I can use it for about a minute before it dies and then reboots. This continues again and again (I have to pull the battery to quit it).
I have stock JB on my GSM GN, but rooted with an unlocked bootloader / CWM. I restored my old CWM backup, and had the same issue. I also wiped the cache and the dalvik just to see if that helped, but I had the same issue. I then tried to do a factory reset in CWM, but after I did that the boot loop just got to the nexus logo and died, entering a new (slightly shorter) boot loop. I went back into recovery and reflashed my CWM backup, and that at least got me back to booting into android.
I can't understand what's going on - could it be a hardware issue if it will happily stay alive in recovery, but dies after 1-2mins of android?
Thanks for your help. If it is hardware then I hope I can reflash the stock recovery / bootloader and unroot through recovery... the phone doesn't stay on long enough to do it when it's booted into full android!
I am completely stock, no root. Phone has been working fine, but for the last 3 days, it will sit at the Google boot logo for 5 to 10 minutes, then start booting. I already did the factory reset back to defaults, 3 times. After the factory reset it will work normally or about 3-4 hours and then its back to taking 10 minutes to boot. I have not loaded any apps on the phone since the factory reset, just my exchange server settings for contacts. It is a pain, because I have multiple batteries. After the phone is done booting, everything works fine, nothing is slow.
Any recommendations?? I have the warranty on the phone, is it worth making a claim? Do they replace it with another nexus, or will they give me a S3?
Thanks All.
It might sound dumb, but are you shutting your phone down properly? If not, your phone will do the equivalent of a chkdsk (Windows check disk) on boot to ensure the integrity of the system/data files. This will usually take several minutes during boot-up.
I hold the power button down and then tap power off and wait for the phone to turn off.
Is it possible for the internal memory to be going bad causing a check on boot-up?
Is there a way to log what is going on to see maybe what is causing the issue?
Thanks.

You could always pull a logcat.
Unlock bootloder flash cwm flash a 4.2.2 ROM and profit. I don't have that issue with 4.2.2. Had it with older versions.

Replacement
Sounds like time for a warranty or insurance replacement.
A few months ago, the display broke on my Moto Z Play. It took me awhile, but I finally got a replacement display.
During the time I was not using it (starting immediately after it broke) it would make the sounds for my calendar notifications as they would come up, and continued to do so until the battery died.
While the battery was dead, I carefully took off the remnants of the old broken LCD.
About two weeks before I got the new display, I plugged it into my computer to see if I could pull any of my information off of it. Unfortunately, I was unable to get it to show up as a drive on my computer so I couldn't pull anything off of it.
Since it had power, it once again made sounds for my calendar notifications until the battery died.
I got my new display in the mail a couple days ago. I set about installing it and after I was done, I charged the battery to 96%. The charging screen appeared perfectly normal. I had no indication that there was going to be any problem when I went to use it until I powered it on at 96%. It looked like it was going to boot up just fine and made it three screens (not counting the triangle screen) into the boot up process and restarted the process.
The last time the phone was fully functional (as well as while it was on with a broken LCD) it was running OmniROM and it has TWRP 3.2.1-0 recovery on it.
First I tried clearing the cache and dalvik cache. That didn't help. Then, as I keep a copy of the zip for that ROM on my SD card, I decided to reflash OmniROM and 8.1 gapps. That didn't help. So, I decided to do a nandroid backup. It got part of the way through the back up and failed at system image. So, I decided to try to backup my data so that I can at least hopefully restore some of it at a later date on my computer or something. Thankfully, I was able to successfully backup my data partition.
After the backup finished, I decided to attempt to dirty flash CosmicOS.
However, I experienced the same boot loop.
I then did a full wipe and did a clean flash of OmniROM.
Still: the triangle screen, 3 seconds of the boot process and then it starts over again.
I am lost as to what to do now.
Help!
Hello?...
Hi, my 5X got itself into a bootloop state I have no knowledge of and I would really appreciate some pointers.
I searched the forum but I'm still not sure what I'm looking at and more importantly what to do about it. My main concern is not losing my data on the device.
Short summary: unlocked bootloader and rooted, bootloops, difficult to power off, factory images flash successfully but still only bootloader boots. The phone is on the latest stock Android 8.1 and was rooted with Magisk. In the meantime I've reflashed all factory images except userdata with no luck.
Bootloops: the phone started bootlooping by itself overnight. It was on the charger for a top-up and running only a sleep monitoring app like any other night. It boots as far as the Google logo, pauses a bit and repeats.
Power off: if I leave the charger cable connected the phone powers off from the bootloader menu only as far as the charging display and then starts bootlooping. If I first disconnect the charger it does power off, but as soon as I reconnect the charger the phone turns on and starts bootlooping.
Reflashing doesn't help: all factory images reflash successfully but the phone still won't boot into anything other than the bootloader. Booting into either the standard recovery or TWRP goes straight into the same bootloop. FWIW I also obtained the latest cache image and erased and flashed that but no luck.
My main concern is not losing my data so I want to be careful with whatever I try next.
I'd be really grateful for some pointers on what I'm dealing with and what the options are, thanks.
