[Q] Phone stuck rebooting - Galaxy S III Q&A, Help & Troubleshooting

Really hope someone can help me here.
I rooted, and put CM10.2 on my phone a month or two ago (don't play that much with ROMs, etc), but fancied a change from stock.
Anyways, it's been fine (although battery life not quite as great as before, but hey ho), this evening just got a WhatsApp message, dropped the notification bar down, clicked on it to open Whats App, and the phone rebooted... And then continued to just reboot over and over after 2-3 seconds (showing the i9300 Samsung logo with the red ! in the top left).
Removing battery stops this obviously, but weirdly when I put the battery back in boots straight away, and continues to just loop like that. Holding power, home, vol up/down makes no difference (been playing with this for about an hour now, and searching other peoples solutions, someone said 5 times wait, and release). Just can't get anything other than this loop, just weird that I can't actually turn it off either.
Suggestions please?
Thanks Gunja

Booting as soon as battery is inserted indicates power button sorted out, try wiggling it or seek a repair.

Yes I believe thats the case, as I have actually got it into the "Accept different OS" mode, stays there for 2 seconds and reboots. Nothing seems physically weird about the power button.
It did the sudden die thing a few months back, and I returned it to Sammy UK and they fixed it (due to 2 year warranty) in 2 days. It's still under 2 years old, so will give them a call. Was rooted before, but didn't show the red ! in the left left. Hope that they don't mind that, as this does seem to genuinely be a physical hardware problem not software.
If you just hold the power button on the S3 when it's booted, just it just turn off eventually? How annoying, 2nd problem with it in the last 4-5 months, wonder if will get another sammy when upgrades due in a couple of months. Lets see how their support is again this time round!

Screen won't turn on

Hi I have been having this tablet for almost a month now. I have been experiencing when I press the power button to wake the device up, the screen won't turn on to the unlock screen. Its random but it happens to me at least 4-5 times a week. Any of you have the same issue? Is this a known issue cause I'm seriously thinking of returning this device and get an ipad instead.
I have only had my tab for a couple of weeks now, but I have had this happen to me once so far. Was slightly concerning, as I thought it had died for a moment.
EDIT: running version 3.2
Happend to me when I was still on 3.1. Update to 3.2 solved it.
my tablet came with 3.2. i have just written an email to sony. will let you guys know how it goes
happened to me three/four times in total and I had it since the launch. I used reset pin hole to fix.
Hi. I have the same problem. It can happen for 10 times a day. It's really annoying, and I don't know what to do.
Tried hard reset, but problem still remains, even when using only pre-installed programs.
Please help
Yep, I have had mine for about 2 months, never had an issue, went to go turn it on yesterday..... nothing.... so i figured the battery was dead, plugged it in.... nothing.... let it charge all night..... nothing.... tried to reset.... nothing... the light by the power button comes on when plugged in... orange charging, green ready, flashes orange when i reset it, but when i hit the power button, nothing, and the screen doesnt come on. I have had it with Sony and their piece of **** equipement, everything they have came out with since the PS3 has been junk!
I have had my tablet since it launched and this has only happened to me once. Using the reset pinhole fixed it right away. I would exchange it if this happens frequently.
After two months, this just happened to me for the first time about an hour ago... Odd. Pin hole reset fixed it.
Yeap sony suggested me to do the same it's been going ok so far. Another small issue happens to me is that it sometimes hiccup from sleep I had to press the power button twice to turn the screen on
I went to store and just ask for replacement. Now, with the new device it seems everything to be fine
The help guide is very useless yet useful for the Tab S because it says "You must access this page from your tablet." <-- It's broken, so how are we supposed to do that Sony?
But you can find a version of the help guide through loads of 404 errors, and it says prod the reset button with a paperclip (not a needle, a paperclip) and the power button will flash. Then boot up the tab like normal.
This worked for me, which is good because I thought the screen broke as I dropped my alarm clock on it. No physical damage so if I wanted to, the warranty would've covered it
I finally got my tablet back from Sony.... they said they found nothing wrong with it, but it works now, so far no issues. (this is after 2 days of me trying to get it to turn on, and about 3 hours at the store with the repair tech trying to get it to work, hence why they sent it in, and magically Sony found nothing wrong)
Try turning the screen brightness down to 98-99% and not 100% I found that worked for me

G-Tablet Quit working after 6 months. Need advice

My G-Tablet was working great for the last 6 months, the day I bought it, I flashed it with Cyanogenmod 7. Last night I was listening to Pandora, while reading Manga. I set it down and went to sleep.
When I awoke the Tablet was off, still plugged into the AC adapter. And refused to boot. After trying to get into the recovery thinking somehow it bricked itself, I noticed the screen would flicker ever so dimly. So I ripped the back off and unplugged the power thinking maybe it's not really off, maybe it's locked.
Alright, so now after holding the power button down for about 30 seconds it starts booting, I see three birds, the words android, the Cyanogenmod logo and then it goes black. After about a minute of that, I assume it booted. Still starting at a completely black screen I pressed the volume button + and - and I hear the beep boop. Alright so it booted. Where is my VIDEO?
I hold down the power button for a minute, I press the volume buttons but no sound. Ok, it's off I'm guessing. Lets boot again. This time nothing, completely blank screen, until it gets to the Cyanogenmod Logo. The video comes on for about 3 seconds then off again. About 15 seconds later, it comes on and I see the android robot riding the skateboard for about 3 seconds, then black again. It again finishes booting, I play with the volume buttons and I get the beeps. But absolutely no video.
One other thing, is that while booting. It ALWAYS turns on the video for the little robot on the skateboard for 2-3 seconds.
Has anyone experienced anything like this before? I'm totally at a loss, I really hope the GPU is fine.
I miss my tablet
If it turns out to be a hardware problem you should have a year long warranty from viewsonic. Someone who has had experience with the warranty process will have to tell you whether or not they will deny your claim if it arrives with CM7 installed (I haven't dealt with them). If you are able to NV flash before sending the tablet back in you should be golden though.
Thanks for the advice Bret.
I had the tablet sitting on my desk, I booted it up, still a black screen but I could hear the volume beeps. I let it sit there for about an hour, running on battery. And wouldn't you know. The screen came on. It's been working perfectly so far, I can reboot, shutdown, let it sleep ect. Not a single problem. I would absolutely love to know if it was a software glitch, or what. Seems my GPU is fine, rocks 3d apps no problem.
But I know if I don't know what caused this, more then likely it'll happen again and I'll flip out.
Open your gTab up and reseat the cables going into the LCD panel.
You say you have been running CM7 for ~6 months? have you had to reflash you system at all in that time?
The reason I ask is that I have had issues of the system corrupting itself over time, and almost every time I had reflashed, everything seemed to go back to being fine. Who knows... maybe its time to do a backup and flush the system for good measure..

[Q] No Power at All

So something very weird has happened..
I had my phone plugged in charging as I was going to sleep, everything was working fine. I wake up 4 hours later, and go to check my phone but nothing happens, and I notice that I have no charging light, nothing. I unplug the charger and plug it into my computer...nothing, I try a different cord...nothing. I tried holding the power button, but still nothing. I'm really confused as to what could have happened, because like I said it was just sitting there charging, I don't keep any open water anything near it either, so that couldn't have happened.
My phone is rooted, and is s-off, I was running MeanRom 4.3 when this happen, and it had been on that for 4 days without any issues.
Any Ideas what could have happened, or what I can?
so quick update, phone started rebooting like crazy all of a sudden. I heard it vibrate on my night stand, and noticed it was on the HTC boot screen, then it went black, and did it again. So I held power+volume down and got to the bootloader, but again it just randomly rebooted while it was in bootloader, as it was restarting it made it to the start up animation, however just went black again for about 3-4 mintues, then started rebooting again....I am very confused...
Well I had the same problem, but my phone Never got reboots or anything just dead.. Ended up with service on guarantee and they had to change the moderboard of my phone

man I hope that not the issue, but its rebooting like crazy now, and I actually rebooted enough to fully boot at one point, and the weird thing is, the Back buttong, home button and recent apps button were flashing, just like they do when you hold the power button in...

I had the same problem with my first 2 EVOS, the just went dead but in my case they never came back up, Sprint replaced both under the 2 weeks warranty period... Bad batch maybe?

Well looks like a trip to Best buy at lunch today (I have the Bestbuy insurance because there is no fee for insurance claims...)
I'm just worried that while I'm there that it will try to start bootlooping, and they will see the text on the "Quietly Brilliant" screen, or it will go far enough to show MeanRom's boot animation, and they will stop the thing on the spot. After posting this morning it has had 2-3 sessions of wild boot loops, where it is continuous every couple of seconds rebooting. In the 3 minutes I've been typing this, it has gone through probably 10 cycles, each time making to the end of the Quietly Brilliant HTC screen where it shows the "This build is for HTC Development only..." yikes...
Best buy doesn't care if its rooted man. I brought in 2 rooted EVO's and exchanged them on the spot. Most of them don't even know what root is. If they did they don't know about the HTC dev screen.

Zperia Z5: LEDs Flash, Then Phone Reboots

Random Crashing
I am experiencing random crashes where the phone stops and the LED flashes a few times before rebooting. At first I thought it was overheating, as the phone was quite warm the first few times, but it has just done it when cold. It has happened mostly whilst in the play store. It's crashed about 15 times in 4 hours.
Has anyone else experienced anything like this? Is there anyway to access the logs without root?
*** Edit ***
This must just be a dud device. I did a factory reset last night and it crashed rebooting. Will take back to shop and hopefully exchange for a new one.
Did u tried to repair it via PC Companion?
It comes from a bad battery voltage. I had One m7 and after 1 year this problem begin. They change the battery and battery conector and it comes to work good.
This happened after 5 minutes, it's been sent back to the shop now for repair / replacement. Shame, as it was a nice phone when it wasn't crashing!
I had kind of the same experience with my device I bought yesterday. Turned it on, worked for about half an hour before flashing the red LED a few times and shutting down. After that it turned on once again, booted halfway up, the red LED flashed again and it shut down again. Then it did not react to anything anymore.
Plugging it into the charger did not yield any reaction at all. Pressing On and the Vol+ button made it vibrate three times as its supposed to do, but afterwards even that did not work anymore. As a last resort I pressed the hard reset button in the SIM slot, which also made it vibrate three times without any other reaction.
So I concluded it was dead and returned it to the store this morning to get my money back. I think I will hold of of buying a replacement until all the errors that currently pop up are sorted out.
Also noteworthy is, that while booting up and in the time it was usable the screen had a red tint sometimes and touch was working rather flakily.
They sent me a brand new phone, so was def a dud. No crashes so far, finger crossed

Samsung Galaxy S2 i9100 Won't do absolutely nothing.

I have a certain problem with my Samsung Galaxy S2. It's a bit old now, It has about 4 years with me. A couple of days ago, I was charging my phone and it was a bit hot. And I recieved a call. I answered it, and the phone went black. I tried turning it on and, nothing. All it showed was a blue screen with a black circle on the top left corner. The phone hasn't gotten any bumps or has fallen out of my hands or anything of that nature. I decided to turn it off, take out the battery and not touch it for a day. I placed back the battery the next day and, this time, nothing shows up. Today, I decided to use it again, and connect it to my laptop, and the laptop detected it. I really don't know what to do. Is there a fix for this problem? I'd appreciate your help. Thanks.
is downloadmode working (when phone is off, do voldown+home button + power button)
