[Q] Nexus Prime continuously rebooting

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

Strange issue, need a little help.

I was on my phone, checking XDA, reading news and so forth. I put the phone down to grab some dinner. When I got back after eating I picked up my phone and it was unresponsive.
I held down the power button for a while and nothing.
I did a battery pull and I was able to boot to the Google splash screen with the unlock symbol. Unfortunately it just hung there.
I pulled the battery again, this time I booted in fastboot, then recovery. The clockworkmod recovery main menu came up in recovery, but when trying to do a restore or anything… The blue menu would disappear and not come back. I can get to recovery, but I am unable to do anything with it.
Last night I flashed to AOKP B26 from AOKP B25. I wiped cache and dalvik. I did not do a full wipe, but according to the dev you do not need to. This morning I flashed Morphic’s kernel TNP138-RD-FUV. I used this kernel on B25 with no issues for several days as well. I wiped cache and dalvik before flashing the kernel as well. CPU was set to the default 1190 and default voltages, with the on demand governor.
It is weird that I didn’t have any issues until hours later and the phone wasn’t even in use. It is as if it wiped itself. I am wondering how and why.
At this point I am going to do a full factory ODIN restore. I don’t think there are any other options.
EDIT, as posted below:
I was getting ready to do the ODIN restore when for the heck of it I decided to let it boot normally one last time. What do I have to lose.
I booted to the Google splash screen and set it down. I got a drink and took out the trash. When I came back I noticed it was at the boot animation! It sat at the boot animation for another couple of minutes but 10 minutes after pressing the power button I was booted up.
I let it sit for another 10 before I played with it. But now its like nothing ever happened. And it boots regularly now. I even booted into recovery and it is functioning as normal.
Any ideas what happened?

In cwm is there a 'go back' option at the bottom? If not scroll up and down a few times passing from bottom to top (looping) until it says like back button activated. If back is not active power button makes screen go off and on and does not select.
This is if you are not using touch enabled cwm.

if you can get into cwm then try fastboot and flash the factory images from the boot screen

I am not using the touch enabled. I know that if you cycle through the menu too much it will disable the select button, but if you keep cycling it will enable it. This isn't that.
The screen is on, I can see the clockworkmod recovery & version in the middle of the screen. Just the ICS blue menu disappears completely. no go back or anything. just a black screen with the clockworkmod info in the middle. It is as if its thinking but it just hangs.

id suggest you try to use ADB from recovery to try and at least pull the sdcard files first of all
second id try to flash another recovery from fastboot then boot to recovery and flash a rom or restore backup
if the above doesnt work then factory image from fastboot is it

Did I just BRICK my G Nexus?

So, last night I was out and about - just having a good time. Noticed that the battery on my GSM Galaxy Nexus was getting low. Went "Meh, wasn't the first time it's died." It got to 1% battery power and shut-off, like it normally does. Me being who I am, I turned it back on to see just how much more juice I could get out of it.
Phone booted up alright. Finished the boot animation, and then a couple seconds later turned off.. not a big deal. I get home, plug it in, and the charge screens cycle..... and then they cycle again. And again. And again. Basically just looping. I turn the phone ON, finishes the boot animation and... turns off again riight away? Goes back to the charge screen loop.
I'm not talking about the regular charge screen. After the battery gets 'filled' twice, it completely restarts. Black screen for 2 or so seconds, and then it goes through the charge animations as it would if you had just pluggied it in. I CAN get into bootloader, but that's about it. I'm just curious.. has anyone seen this before? Or know what my problem might be?
I'm unable to turn USB Debugging on in the system settings, so I'm at a loss as to how I can fix this issue WITHOUT bringing it into Bell.

Try going into recovery and wiping cache and dalvik. If that doesn't work reflash your rom

My phone is completely stock (I reflashed it to to the stock yakju? I believe it was when I found out Samsung had screwed people off the google update path.. so I can't get into recovery mode. It just shows the broken android. It's all been re-locked, and since then, my laptop has died. So I no longer have the ABD/Samsung drivers setup. Which was a pain to get going the first time..

The "Broken android" IS stock recovery. I believe that when you push Volume Up seeing that image it takes you to the stock recovery menu. But you can always reflash Yakju or any other ROM through fastboot mode (see the tutorials here on the forum).

Turn it off. Leave it charging for a few hours before turning it on.

You do not need to have USB debugging enabled to use fastboot.

It doesn't take long at all to install the drivers. Look for a thread with "universal" in the title. I think it is in GN General. Once you do install the fastboot driver, download the fastboot.exe file and reflash the stock ROM.

It's volume up and the power button.

The problem I have is that the charge animation doesn't change... i.e. It'll constantly refill the battery and all, but it always starts from the bottom (While when a phone is say... half charged, the little battery is half filled and the animation continues.
I'm not sure it's even charging at all.

Update time!
Got it into the stock recovery. Wiped the cache and all of my data. Rebooted, and.... it turns on! No longer reboots on regular startup. That's the good news. So at least it's somewhat useable now..
Now for the BAD news.
-It still does that retarded charging bootloop that doesn't seem to get me anywhere
-....When it's on. Like, running, it doesn't charge. Nadda. Zip. Zilch. Computer, wall charger, android dock, nothing. It just won't charge when it's on. However when I got it to power on, it said I had 14% remaining - which means it was likely charging inside the Bootloader, as I had it on that for quite a bit.
I think this just went from a software to a hardware issue. Thoughts?

Power down phone, do a long battery pull, place it inside again, let it charge for a few hours without powering it on, when it is fully charged (or after a few hours) pull battery again and then take charger out the phone. After a few minutes, place battery inside phone again and start it up without the charger.
Hope that works.

And that might fix this charging bootloop? Because the LCD doesn't even turn off..

You could always try a new battery

+1 for the new battery thought.

Battery test
I am having a similar problem, I get the boot loop.
Difference is that I had started with a new battery so that could be your problem or unrelated. I went to a mobile shop yesterday and they let me use a new battery to see if the loop would start. It did not so there seems to be at least one other failure path. I have avoided a factory reset as I was hoping to pull some pictures but coming to the realization that I will have to try factory reset as a last resort
I posted to this thread #192

My Galaxy Nexus phone from WIND went into a reboot loop yesterday. It had been charged to 98%, used to make a call and then put away. Wireless was enabled. Noticed vibration periodically and say it was rebooting every 6 - 7 seconds. Pulled battery to stop reboot. Saw references to fully charged battery via USB stops reboot loop so tried that. Battery voltage was 4.17V and still went into reboot loop.
Tried to boot into safe mode but still goes into a loop
I went into recovery mode and tried all options but factory reset because I am hoping to recover some pictures
reboot system now
apply update from cache (but did not have an update to install as only options were ../ lost+found/ recovery and when I selected these was in a loop as well)
wipe cache partition
Can't tell what version of Andorid I have as the phone never finishes booting.
Boot console gives the following information
Product Name – tuna
Variant – maguro
HW version – 9
Bootloader version – PRIMEKK14
Baseband version – I9250UGKL1
Have installed SMS backup because I was planning to do a backup after a trip. Also have two GPS tracker apps installed.

If you can boot into recovery, you may be able to get your pictures off your device.
1) Make sure you have the drivers for your device properly installed on your computer.
2) Download the attachment and unzip it to a directory on your computer.
3) Open a command prompt in the same directory.
4) Reboot your device into recovery and plug into your computer.
5) Make sure your computer sees your device by typing: adb devices
6) Pull the data off your device by typing: adb pull /data/media
Note: depending on how much data you had on /sdcard, this could take a while, so be patient.

Stuck at HBOOT after good flash

[[[{HELP}]]]
So, I have just rooted my HTC Wildfire S (CDMA/marvelc) and flashed a build of CM9. From that point i realized that I was stuck at HBOOT every time i booted my phone, so I proceeded to enter recovery mode. In recovery mode i performed a factory reset and cleared the cache and the dalvik cache. After making sure my phone was completley clean, i reflashed CM9. IT BOOTED!!! I was very happy so i began making customizations to it. Later that day (yesterday) i was going out to dinner and had noticed my phone had a low battery charge. to stop it from running out, i turned it off. when i got home it booted into HBOOT and would not boot CM9. Though i did find a trick around this, i entered Fastboot USB and typed this comment 'fastboot oem boot' and like magic, the phone turned on. Just to test i powered off my phone and turned it back on. It was stuck in HBOOT again. I got out using the fastboot command. the same thing happened when i restarted my phone. So, it clearly flashed well but there is something wrong.... I flashed using the latest build of CWM. the build is CM version 9.0.0 Any help would be much appreciated!
Thanks,
Matt

[Q] dead s3?!

HELP! i'm running liquid smooth on my S3 right now. the phone has been having issues, shutting down on its own, and i was going to load the stock rom to send it in for warranty.
the last time i was able to use the phone, a message popped up saying "System UI has stopped working". later on, the phone shut down on its own and when i turn it on, it gets stuck on the liquid smooth boot screen forever. i plug it into the comp, still nothing.
is my phone dead at this pont?! any way i can load the stock rom onto it or get it back to functioning?!! argh!

You can always go to recovery and do a factory reset that should get you booting again with liquid smooth if you want to go back to stock boot into download mood and from your computer Odin back to stock. The links can be found in Android dev section.
To boot into recovery from phone off hold volume up+home+power and to boot to download volume down+home+power
Making the iPhone jealous one user at a time.

Sounds like a framework issues to me. I would backup your ROM and then clean install after factory reset and cache wipe from recovery.

If you can get in to a custom recovery. You can use this.

I use it from time to time. No pc, complete stock totally on the phone itself. You will still need to wipe your internal storage. I do that first.
I use Phil's recovery.
