Phone keeps restarting before Samsung logo - AT&T Samsung Galaxy S II Skyrocket SGH-I727

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?

[Q] Liquid Thunderbolt Problem

Hello. First and foremost i am noob, but i fee like i've given this site a fair scrub for my situation and i haven't found anyone in a similar situation. I have an htc thunderbolt, I am not sure about any of the software versions, but i am on verizons network. I recently rooted my phone. The rooting process went fine. I then went on to install the latest version of liquid thunderbolt using rom manager. The install seemed to go fine. IT go to the point where a graphic loaded on the screen. I think its the liquid thunderbolt loading graphic. It's like this vortex-like thing with a bunch of lightening in the middle and then a water drop surrounded by lightening. Either way it's been stuck on this screen for the past 4 hours. What should i do? Is my phone what htey call bricked? If so can i recover from it? Should i just yank out the batter?! PLEASE HELP!
What you are describing is happening to me right now as well. Have you found out any new information. btw My tb has been rooted for 4 months with no troubles. last night i put clockwork mod/rom manager on it went through the process step by step then selected a new rom I think it was from liquid thunder. Now no mater what i do the phone boots up to the htc screen and then to rotating screens just like you described. that's it nothing else. it will not power off without to pulling the battery. i have pulled the sd card. it will not boot into hboot. press down vol. then the power.
thanks,

Hi, this is Jarrad's wife and I have fixed his phone. I was asleep last night when he did this to his phone and he has been up all night working on it. He even went as far as to make me breakfast in bed in order to soften the blow I guess with regard to the information he was about to tell me about his brand new very expensive phone, since he knew it would piss me off. So anyway he had the phone off for about an hour and a half on the charger and stopped messing with it. After he told me his story of what he did to the phone I decided to take a look at it. He told me that when you go into recovery you push and hold the power button and the volume down button at the same time but, this is not true or at least its not what I did to get him to the recovery screen. I was going to turn it on but, forgot he said it had a problem, so after holding down the power button ALONE for about 5 seconds I then pushed the volume down button and held them both together and boom the recovery screen came up. Now it was not a fluke because he then used the wrong recovery option and locked it up again. So, again a pressed the power button ALONE for about 5 seconds and then added the pressing of the volume down control button and boom back to the recovery screen. I hope this works for you the way it worked for me. Good Luck.

Infuse acting crazy!

So last night I dropped it. It was fine I have a ballistic case. Then pulled it out of my pocket 1 HR later and the Samsung boot logo just keeps repeating. I take the battery out, and as soon as i put it back in it starts doing the same thing. I tried recovery, download mode, plugging it in. Nothing! same thing over and over. Then I just put battery in and pressed the power button over and over probably 40 times aand it starts up and runs fine? It came back on last night for about 30 minutes then did the same booting problem. Do you guys think I messed something up by dropping it? I haven't flashed anything in months. Should I take it and get a new one?

probably ANOTHER broken power button...honestly, seems like everyones power button is failing these days...its starting to become common...one user had luck with this: http://mobiletechvideos.mybigcommerce.com/samsung-infuse-4g-power-button-repair/ i think jscott suggested taking off the phones casing and dusting the inside where the button is with compressed air to clean off the contacts, another user has mentioned to completely desolder the power button and use a usb jig to power on the device...do any of the following at your own risk, i cant guarantee any will work...
Well it hasn't happened again. Clicking the button a hundred times might have fixed it hahaha.

[Q] Power button is causing phone to reboot nonstop

So, tonight I just turned my screen on and then off real quick to check if I have any messages and set my phone down. Then I look down and see the Samsung logo. I'm a bit confused and notice that the Samsung logo keeps showing for 1-2 seconds going black for 1-2 seconds and then back to the Samsung logo for 1-2 seconds, over and over. I pull the battery and then when I put it back in, the phone starts doing it again before I touch any buttons. Clearly something is causing my power button to be "on" continuously. This seems to be a relatively common problem from doing some searching, but most of the posts I find seem to be full of people responding who fail to understand the problem. People seem to think that this is a boot loop and that it can be fixed by going into download mode. This is clearly not the case, the problem is obviously with the power button since the phone automatically starts up and keeps doing this as soon as the battery is reinserted regardless if no buttons are pushed or all buttons are pushed. Has anyone managed to fix this problem? I'm thinking I'm going to have to take the infuse apart and see if the button is stuck or if there contact occuring somewhere it shouldn't be. Any help would be appreciated.
Yeah, i have this problem. First what i did, i'd hit gently the power button a few times and it seemed to work. But after a few days it got worse, till the point it wouldn't work. I decided to open up the phone myself, and trying to manipulate the small power button. Apparently it worked, but i decided not to use the power button anymore, i wake the phone by touching the volume +/- buttons and i turn it off with a widget i downloaded from the playstore. This problem seems to be on every infuse i'm saving up some money to buy another phone, since i won't be able to sell this one with this problem.

Here is a video of a screen replcement- not what you are doing but it shows you how to take the phone apart. Hope this helps.

Thanks for the link. I took it apart using that and cleaned everything and just clicked the power button a whole bunch and its working again for now.

[Q] GS4G keeps reseting every 3 seconds

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.

32GB-Boot takes long press of power button (10 plus seconds). Is that normal?

Hello XDA,
I've done some searching but I can't find a post like mine. I'm not in need of troubleshooting, just a question:
I've had a Nexus 5 32gb for awhile. It runs just fine, but it's always had a "feature" which I didn't realize was unique to this phone until just the other day:
Turning the phone on sometimes takes a long press of the power button (10 plus seconds). Sometimes I have to do this a couple of times and then it will boot. Booting into recovery is the same way. When powering off the phone, it takes about 15 seconds to power down, almost like it's just down like a computer. It will not restart. While the phone is booted I can long press the power button to restart it, and the phone will turn off but not restart. Also, from the bootloader I can choose restart but the phone won't restart. It just powers down.
I never assumed this was abnormal as this was my first nexus device, but I recently acquired a 16gb Nexus 5 and it does not behave in this fashion. It boots almost instantly and restarts.
So the question is, is that normal for a 32gb device? The phone has a new power button and new battery so pretty sure that's not the cause or contributing. Phone has not been rooted or unlocked.
Any thoughts?

Hi, that's a good question. My first thought for this problem would be a sticking power button cuz I've had one of those issues before and the phone was stuck in a bootloop because the button was stuck on my 16Gb N5. I would think this may have been the issue but since you have a new power button I wouldn't think it would be.
I recently got another Nexus 5 and this one is 32Gb but when I go to power it up, it starts instantly. So I would imagine that this is either a hardware problem and not something to do with the software. You may have to get it checked out at a phone place if the community can't find anything on this. (That and I've not seen this issue around before)
This is just my thoughts on it, Good luck!
Well I fixed it. I didn't set out to, it just sort of happened.
I disassembled the phone to replace the camera lens and thought what the heck, let's look at the power button. In doing so I noticed that the ring in the trace next to the power button was exposed, and there was only a miniscule amount of solder connecting the trace to the button. I mean hair width amount. I thought that can't be right so I opened up my 16gb and low and behold there was definitely more solder bridging the trace and power button. I thought what the heck and added a tiny bit more solder to the 32gb, completely covering the ring and thickening the solder connection.
SOLVED! Starts right up now, no problem. It even restarts too. I can't explain is but my non engineering theory is that there wasn't enough capacitance for the connection to be completed so the boot and restart processes were retarded. Either way, fixed.
So if anyone else runs into this problem, take a look at the connection. Hope this helps someone.
