I recently flashed CM9 (throwing that out there incase it is of some reasoning but I doubt it) and I've had my phone since November.
I flashed CM9 9/25 Nightly like 2 or 3 days ago (absolutely love it by the way, smoothest build/rom for the Skyrocket thus far) No problems with the Rom I might add, just my phone had just randomly restarted on its own twice while using it (nothing happened, just started right back up).
However the 3rd time, it randomly restarted and never booted back up. It vibrates and then reboots before it even gets to the Samsung screen and reboots/vibrates again (2 second intervals or so). The furthest it gets is like 5 seconds into the CM9 logo and then it'll reboot. It does the usual thin white line as it restarts and just gets stuck there. Can't get to Recovery for more than a few seconds before it reboots (not long enough for Touch to settle and do anything) and it won't get to Download Mode fast enough. Any ideas or any way to get data off /emmc? Don't want to lose a bunch of pictures/videos.
I have a replacement coming within the next days so I have about 2 weeks to either get lucky and get up long enough to save my data or somehow find a solution (doubt it). I already took it apart and swapped screens because I had busted the screen before and put the broken one in incase by some miracle the new one was causing it (no luck).
No water damage or anything to the phone, just randomly rebooted those times while texting or listening to music/what not and now it's pooped.
Any suggestions?
Tried without the battery (via usb/pc or AC source), without sim/microsd, etc. and nothing. Assuming I'm just SOL.
Edit: Side note, I got terrible battery life with this phone. I could only get 2 hours of screen-on time if I was LUCKY on Mobile and maaaybe 3 if I was on WIFI. The most I ever got was 5 hours on WIFI with a 3850mAh Extended Battrey (so even though it was a cheap battery, I'm thinking the phone had a problem from the get-go).
You Could Have A Stuck Power Button. To Fix That Try To Repeatedly Keep Pushing The Power Button Hard To Try To Unstick It. or try taking it apart and clean the power button

This was my first thought, didn't make a difference no matter how I did it. Appreciate the idea though.
[SOLVED] It is indeed the power button.
I took it apart again and thoroughly mashed the power button plenty and gave it a good few breaths of fresh air.
After that I realized that, I put it back together and realized that if I held the power button right after the phone vibrated it seemed to get to the CM9 symbol more often.
So I mashed the power button a ton more, shook the phone like hell and smashed it against my palm a few times and...it booted! I was able to get everything off of it and reset flash/counter/restore to stock all without ever touching the power button. Screen Timeout @ 30 and using ADB is your friend. Now just to see if it magically works till my replacement gets here lol.

i know its sounds too simplistic as to blame a sticky power button and users dismiss the idea because they'll blame themselves, a bad flash, or the rom, but a reboot at a 8-10sec interval is the power button internal switch making contact, sometimes its an easy fix or sometimes it takes more than a few tries, or taking it apart to clean the internals
My phone goes anywhere now from 10 seconds to a full day without having a reboot with continuous vibration at 2 second intervals. Flashed to stable ROM's so that's definitely not the issue. I've had this phone since Christmas 2011 so I'm assuming I don't have warranty? You guys just unscrewed the screws and got into the internals I'm assuming?
Hello.
I have searched the forums about my issue, and although there are a lot of threads about phones rebooting, there was none about such exact problem as I am experiencing. I apologize if I missed a thread which tackled this problem.
Symptoms:
1. my galaxy S 4G reboots about every 3 seconds: it only gets to the very first "Samsung Galaxy S 4G T-mobile" logo, and reboot
2. it is possible to access boot menu (volume up+down), but only for a split second, and phone reboots again
3. rebooting starts as soon as in put battery in, no need to even press the power button
All that started by itself yesterday. I thought it was a mechanical fault with power switch, I opened the phone, unscrewed covers, cleaned everything, but found no mechanical issue. I switched batteries, tried starting the phone of plugged-in charger, on usb cable, took out sd card, sim card, put a different sim card in... and nothing helped.
Phone runs on Gingerbread 2.3, stock by T-mobile, never had any other roms on it. Device is rooted.
If anyone has an idea how to approach this issue, please let me know. Or reply with a link to somewhere I can read more. I was not able to find much on this...
Thank you!

The phone sometimes does a reboot loop if u take the battery out of the phone without turning the power off. Just keep trying to turn it on, and eventually it would reboot properly. Take the battery out of the phone for a few minutes, put it back and try to turn it on again. Do this a few times to see if it boot back properly.

Thank you for a prompt reply!
I did take out battery for a long time, well over one hour, and took out sim card and sd card as well. Unfortunately reboot loop started immediately when I placed battery back in the phone. That's what made me think it was a mechanical issue with power button.
I will try keeping battery out a few times again today.
One other thing: the phone had been in hot and humid environment for about 30 minutes before this happened. Not the first time for this phone to experience high humidity, though. However, I did not find any moisture inside the unit.

I had this happened to my phone. Just wait it out and keep trying to reboot, it will come around. Take the battery out and put it back on. Keep on repeating this step.
Also, when the phone is on, try to hold the volume - + and power button at the same time to see if u can get into boot mode.
Also u can use hair blow dryer to blow dry area around the power button.

You have a stuck power button. Take apart the phone and clean the power bottom with compressed air. Then rapidly push the button in and out for a while.
Resolution:
I took the phone apart, and checked the power button (which had been my first guess), and was seemingly all right.
The battery was also not the issue, as I tried 3 different batteries.
Having no other choice, I put the battery back in, and let the phone happily reboot at its own leisure. After over 20 reboots, the system came on. Then a few minutes later the device rebooted again, and the loop started all over. After a while it booted up again. This time I did not wait for the device to reboot by itself, and I switched the phone off with power button, and then turned back on, and it booted normally. Repeated this once more - normal boot again. One more power off, and I entered the boot menu and did factory reset. Once the stock reinstalled, everything would work perfectly - no more issues with boot loop.
So it seems to me as a software problem more than anything else.
Side note: for the last several weeks the phone displayed strange behavior, that is the screen would light up for no reason by itself, and quickly go off. Sometimes it happened once every few minutes, sometimes it happened several times a minute. Did it have anything to do with the boot loop? No idea. But it strengthens my hunch about a software issue, as that behavior also went away after factory reset.
Sorry for the lengthy post, but since I have not found a similar case anywhere in the forums, I though someone might find this interesting. I do not deal with phones except as a user, but some of you guys do it maybe professionally, so maybe this will be a curious puzzle for you to solve.

Hardware not software. You had a stuck power button. By forcing the reboot with the power button you unstuck it. If you don't believe it research Occam's razor. Glad you got it fixed(unstuck) though.:victory:
EDIT: Here are some other people who have had the same issue on samsung phones.

Hello,
So the phone fell from a small height into a toilet today but didn't turn off. Instead it rebooted and now it is stuck in a bootloop, reaching the end of the boot animation and beginning again.
I can't reach the recovery or bootloader. Holding down the bottom button and the power button stalls the bootloop but only produces a black screen for a few seconds before it loops again. Holding the power button just restarts the loop.
I tried plugging it into a pc and checking if it was listed under "adb devices" while it was looping but got no joy.
The thing is sitting in rice while I hunt for some silica gel packets. So on the plus side I have invented flashing rice.
Have I missed anything or do I just have to hope something changes as it dries out?
Thanks.
You should have been drying it out first before trying anything ...
But hopefully it'll dry out and it'll be fine. Tell us how things will turn out.

I was a bit perplexed really, the phone wouldn't turn off so I was looking to make it power off so I could leave it to dry in peace. I felt like it was doing all the damage it would do since it was already on :/
Still in boot loop.

I think if it s still in boot loop that s not so bad... It s still alive.
I would be you, I would put it without case in a box full of rice during at least 24h. It would help to dry it. It would have been better just after the incident but maybe it s not too late. Good luck...

Drying methods
The good news is that water repellant treatment is applied to most Motorola phones. Even so, small droplets of water sitting on surfaces can cause problems both immediately and longer term (through oxidation). Thorough drying out only possible through evaporation (immersion in rice WILL NOT work with these sealed units, as it's a contact desiccant, which works by capillary absorption of water molecules that it physically touches).
So: power off immediately after retrieving from water; remove back to expose as much of the interior as possible; remove SIM card. Then keep the phone in a warm place overnight (eg airing cupboard). Leave for 24 hrs; then attempt re-activation.
Dropped my Moto G gen 1 phone into water yesterday, took it out within a couple of seconds. It seemed ok, then went into repeated boot loops. Opened it up, no visible water inside (prob because of water repellant treatment).
Followed steps above , and after 24 hrs the boot loops ended and it is now working fine.
Good luck !
A similar thing happened to a moto e, it wasn't dropped or anything but it was stuck in an infinite reboot loop.
I took it to the moto service center and they fixed it by doing a "power charge", at least thats what he called it.
No idea what it means. He connected it to a laptop and voila!, it booted.
Hi,
I am stuck in the same problem. My motog 1st gen fell into the toilet day before yesterday. I took it out within 10 seconds I guess. Tried to switch it off, but it was stuck in the boot up loop and didn't switch off. So I tried using a dryer to absorb all the moisture first and then put it in a airtight bag full of rice and waited for the battery to drain for the phone to shut down. It laid there for 30 hours like that.
After that I tried charging it and checking if it works but its still in bootloop.
Please suggest what to do.
Hi, While on holidays I dropped my phone on the beach and a wave hit it, it was covered in sand etc and it was wet. The phone, however, was still turned on and the screen still worked. I locked the phone, and removed the sand from the charging port and between the buttons. But when I turn it on, it goes to the "1+ Powered By Android" screen, and it doesn't go past that. I also can't reach the recovery screen, but I can get to fastboot mode
I left it in rice for a few days, to no luck and I put it in the hot press overnight which didn't work either.
I also tried flashing the stock rom from fastboot mode, and flash a recovery rom too, but it didn't help at all.
Does anyone have any suggestions on what I should do to try and fix it?
Cheers, Adam.
Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])
Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.
Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway
Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...
Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.
CaptainFedora, did you solve the problem? I have the same issue...
Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.
Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
