Help. My phone is stuck in a boot loop - Galaxy S III Q&A, Help & Troubleshooting

So I was charging my phone, and it restarted itself and now it's stuck in a bootloop!
I can't access download mode or recovery, it keeps restarting before I have the opportunity to press any buttons (hardware or on screen) and removing the battery does nothing either, as soon as I put the battery back in, the phone resets without me even pushing the power button
I'm using Temasek CM11 v8 with the "201113-1248-cm11-i9300-r3p2-linux30101-BOEFFLA-temasek" kernel
Is it recoverable?

I've managed to get it into both Recover and Download mode briefly, but both times the phone restarted within a few seconds back to the bootloop

Sounds like the power button is shorted out, fairly cheap repair if so.

Thanks for the reply. What makes you think that it's the power button shorting?

Holding power button for 5 seconds acts as a hard reset, everywhere.
That's a good starting point actually. There's no reason for download mode to reboot automatically. If it loaded then it waits for the events. Either it works until you do anything with a PC, or doesn't work at all.

hi
try using a universal battery charger and then try again

Ah Well I suppose that makes it pretty conclusive. 2 hours later and it's still bootlooping... I'd take it apart but I don't really know what i'm looking for and I suspect if it's shorting, something will need replacing or soldering etc. Thanks very much

I don't think I have one, I shall check though. Thanks very much

The issue of having it shortly resetting once reinstalled the battery sounds to me like a hardware failure, most probably hard resetting all the time.
A hardware repair should help fix this.

It's funny you say that, after hours and hours of trying to get my phone to work, somehow through more luck than judgement I managed to get it into recovery and flash WanamLite 7.2 (I figured it was the next best thing to stock, as I couldn't access download mode) and well... since then, touch wood my phone hasn't restarted itself even once... now granted in that time i've only touched the power button once, to turn on the device, but it seems like progress to me
So my question is, is it possible that I could of had a bad flash or something? It seems too coincidental to me, and I don't actually think the different ROMs have anything to do with the problem (that is still lingering beneath I suspect), but the optimist in me REALLY wants it to be fixed haha
EDIT: Oh and thank you tweetatoo for your reply

Possible its the well known multipleromflashed problem .

Interesting, thanks. It's just a bit confusing, it seems plausible because I flashed the ROM earlier in the day but at the same time, im not sure how much control the new ROM would have over the phone entering Download Mode... Mind boggling.
I'll keep an eye on it for a bit... and im still too scared to use the power button haha
Thanks very much

Download mode is entirely separate to the rom, I still think your power button shorted out (stuck down) as it's been reported many times before. If you have warranty then now would be the time to triangle away and return to stock for a while, just in case.

[Q] my.phones issue.

For the last two days my phone has been anything off at random... nothing has been changed... I'm on the cm9 nightly from the two days ago... this is the thing tho... If I gentely tap the phone it will shut off or shake it... so I figured maybe after time the batter is lose... but it also is turning off if it sits completely still...unless its playing music. It has not turned off since Round 8 ad I have just had it playing music this full time ...any ideas??
I already did a full wipe and re install and when I get home I'm going to Oden back to stock and redo everything.

My only suggestion at this point is odin back to stock 2.1.
Unfortunately this sounds like symptoms of hardware failure. I had a phone (cliq) which would do the exact thing as you described...the phone would vibrate shut off and reboot unexpectedly. I would open the physical keyboard and it would also shut off...this is totally hardware related from my understanding. But that is the worst case scenario.
Hopefully it is a software related issue in your case. Not much else i can say.

Overclocked? Voltages changed at all from default? If you have anything set in voltage control or setcpu, get rid of them and try it. You could also try booting into recovery and see if you can reproduce the problem. That should also help determine if it is software or hardware related.
If the phone is plugged in it does not seem to reboot. i have not had time to mess with it i will check it out this weekend. Weird because it only seems to be doing this at work? I have not had it restart on me at all while at home.
Also if i have the music playing it will not turn off. This weekend im going to oden back to stock and see how it goes. otherwise gonna try to deal with it long enough till the gs3 comes out, ha.

Help Needed - Galaxy S3 Not Switching On

Hi - I'm using a Galaxy S3 right now and it's not powering on at all. Battery is guaranteed not empty as it has been on charge all morning. It's rooted and running SuperNexus - I9300 - BUILD 4.
I can't even get into download mode - tried powering on with volume keys held up and/or down along with home key and power key but no luck
I've called Samsung and they will take it away for warranty repair but my worry is if they know it's rooted - will they refuse to fix it?
I'm clutching at straws but has anyone got any other suggestions I could try?
I imagine you already tried this, but when it happened to me last, I simply took the battery out for a few and put it back in, then it fired up. Has only happened to me once though.

yeh it's been out for a few minutes. Maybe i should try it for a little while longer.
One thing I forgot to mention is that sometimes I would pick up the phone to look at something and the screen would be blank but the soft keys would be lit up. The only way to get the screen back was to keep the power button pressed down for 10 seconds or so so that it switched off and then back on.
This is what happened this time - but only this time it's refusing to come back on

There's a known issue with some devices having problems with this in here:
http://forum.xda-developers.com/showthread.php?t=1993044
But if your device was starting to have problems before... maybe it wasn't related to motherboard but something else, maybe even software related... But still, if the device is not powering at ALL you should be good with samsung, as they will just replace the motherboard and thats all (at least some ppl had it repaired even rooted and with CM installed on the thread I linked above.
Good luck and share your adventure with the SAT (if you finally send it there) on the other post
If your in the eu then rooting your phone won't affect the warranty. It's been confirmed a few times in the thread posted above. It sounds to me like another mother board failure.

[Q] Help! New Galaxy S Advance Bricked After ODIN Upgrade!

Hi People of the world! As you can see im new to here so yeah i just might be in the wrong section...
So, I just got my shiny android a week ago, and know it sits on my desk, lifeless, like a brick. Like literally its dead! I don't know if I can fix it or the BIOS (if theres one in Samsung Galaxies) is fried, or maybe the motherboard is fried, or the battery overcharged, etc. But I just cant do anything! I'm totally out of ideas!
Heres the problem, I first rooted my android successfully, and played around with my android a while. But as you expect I just coudn't wait for the jelly bean update! So, I desided I would give a try to take the Russian firmware instead. That was already a bad idea, but I read on some threads that it would work fine, so I downloaded one from Sammobile.com. The real mistake? I downloaded the wrong phone. I own a Samsung Galaxy S Advance NFC Version;GT-I9070P The one I downloaded was UnNFC version; GT-I9070. Well, I didn't realize that, and proceeded with entering download mode and eventually flashing the PDA file from Sammobile with ODIN. So I pressed start. It started the process, and after 5 min it said in blue: RESET. I saw the phone rebooting. Now, another big mistake: I started touching the power button, which I shouldn't have done. Then, instead of waiting, as soon as seeing the thing wasnt booting, I took out the battery and unplugged the USB cable. Then after a while the PASS appeared in green. So it went successfully? NONONO Now it wont boot! More specifically, it wont TURN ON! like it wont whow any sign of life. As if it had no battery or USB.
Today I discovered, If I hold Vol UP+Power+Home when its connected to my PC, it makes the beep, shows that it failed to install the driver for "U8500 USB ROM" What the (*^&(&%*(&^&* is that??? Also, in 5 seconds, the device disappears, meaning that I must hold the button combo for another 20 seconds.
So, I've got no connectivity to ODIN, nor Kies, and I cant go into download mode, nor recovery mode.
Any Help?
Pleeaase if you can help youre a super god of androids!
ok, so if I understand correctly, You can't even turn on a phone - no samsung logo, no yellow triangle, nothing, right?

Exactly. Nothing at all.
The only evidence that its not fried is that the computer detects it as U8500 USB ROM for 5 seconds whenever i hold the power button or any combination. Nothing on the phone though.

Ikr its really bad to break your phone as soon as i get it. Worse, for me its a few of days to my birthday! Worse thing that could happen. I will PM you if i happen to find a good solution. Also, to make it really the worst thing, the GT-I9070 is one of the less popular phones (not like the s3). The NFC version? Even rarer! So not only are there not many developers working for that phone, not many people have really encountered problems with the phone at all.

Please help! I also bricked my Samsung S Advance I9070P after downgrading from JB to GB, since JB was updated for India I9070...but the phone bricked after downgrade. Everything was successful and it had auto-rebooted after the downgrade and stuck with Start up screen. When I removed battery and tried again..it bricked! No recovery mode, No download mode, no power on.

[q] brick phone! Wont turn on

Hi My galaxy s2 i9100 wasn't able to turn on, even when i charged it
This is what happened..
i was actually flashing a rom, after flashing i press
"reboot device" in the recovery and it has choices
Yes
No

No
Reboot Now.
etc..
im talking about CM RECOVERY or clockwork recovery i guess.
then i didnt choose any, i just pressed the back soft key and it turned off and the lights of soft keys stays ON but the screen is powered off
so i did pull off the batteries to fully turn off my device, after putting back.. BOOM it wont go turn on by that time...
can anyone help me? or i brick my phone??
help please.. anyone?

Have you tried charging the battery. You can try using a usb jig to boot into download mode and flash a rom through there.
yep, i tried charging but nothing happens, my phone is kinda getting a lil hot when im charging now..
what do u mean by usb jig? ive done the
hold together power+volume up/down and home button.. nothing happens, it just getting a lil hot..
later when i go out ill try another battery .. nways i dont believe that my batt would actually be dead just like this easy. but i dont hope that my phone got brick for just simply actions that ive done (

Happened to me before. May or may not work for you.
Take out the battery.
Wait 1 minute.
Now turn the phone on, and it will take some time(maybe 3 mins) but it WILL go into recovery mode. Do what you want in recovery and then done.

Looks like he's bricked it quicker than Sole Power covered the last furlong in

Weird situation, phone mysteriously not starting, any insights?

Hi there! Long time reader, first time poster (TL;DR below...but it should be a quick read anyways )
So I've been using this S2 of mine for almost 4 years now, haven't had any trouble (other than a couple of battery swaps). For the past 6 months or so I've been using CM 12.1 nightlies without issue.
The events:
- The other day, my phone froze (I wasn't using it when it froze, it was when I went to use it that I noticed...it was on the wifi selection screen if it matters), so I held the power button to shut it down, and when I powered it back up, it just froze at the Samsung boot screen (with the usual yellow triangle).
- At this point, I was able to reboot into download mode at will, but any attempt to boot to recovery just led to the freeze at the Samsung boot screen. Also, the phone would automatically reboot itself at this point any time I inserted the battery (I was of course putting the battery in and out trying everything I could).
- I would have reflashed from Odin at this point, but since I was away for a few days I just kept trying to reboot into recovery, to no avail. On one of these attempts (power+vol up+ home) it showed the Samsung boot screen, and then immediately shut down and I haven't been able to get anything onto the screen since
I'm now home, and I can't seem to fix it. If I plug the phone into a charger, the top half or so of the phone gets warm, and it also seems to get warm if it isn't plugged in and I try to power it up. I was thinking maybe the phone was maybe doing the same thing as before and just not showing anything on screen, but I blindly do the steps to get it into download mode, and Odin doesn't recognize anything (drivers are definitely installed). I have also tried other batteries, no luck.
Any ideas of what I might try? I'm willing to do anything. For the record nothing happened to the phone at all when this all happened (no dropping or water damage or anything, just my attempts at booting into recovery). Maybe I should try a jig? I'm also open to opening the phone if there's something I can do, though I don't have experience with this.
Thanks so much for any suggestions!
TL;DR: phone froze (running CM 12.1 nightly), held power to shut it down, and then consistently froze at the boot screen on any attempts to power it on. After a few attempts at booting into recovery (the phone would only freeze or enter download mode) the screen suddenly shut off and I haven't seen anything on it since no matter what I try. I can't think of anything that happened to the phone I'm open to any and all suggestions! Thanks
One sentence amongst your description stands out like a 'sore thumb'.....
That the device heats up towards the top when you attempt to charge it.......
Until you try a jig I can't be certain, but that heating coupled with a dead/unresponsive screen along with a lack of recovery and/or download modes (download mode is 'hardwired' into the device, and NOTHING should be able to corrupt it) are the primary symptoms of a failed motherboard.......
That is my opinion based on my experience in these forums and personal experience with a (now dead) S2 (one of two that I own).........
Get the jig just to be sure, but I'd be surprised if it had any effect.....sorry to be typing something you don't want to read, but you said it yourself, the device is 4 years old....it's been in service roughly twice as long as most smartphones, and they don't last forever....

Thanks dude! It's nice to have some idea of what happened. I am indeed very happy my phone has lasted me this long, and my friend is gonna give me an extra S2 she has anyways it seems so it's all good!
I'll try the jig and update here with the result (I ordered one online...will arrive in January sometime)...just in case anyone is curious.

Sorry it took me a while...the jig was in the post haha. It didn't do anything at all (no response when I plugged it in) so I think it's safe to say you were bang-on and the motherboard failed! Happily using a new S2 (with CM13.0 now ) on behalf of my friend though.
Thanks again.
Sounds familiar. Happened to me also due to failed cyanogenmod update (CM13). Only thing that works is download mode, so i'm not given up hope yet.
I can't post a link but google ''Apply Update Failure samsung galaxy s II'' there's a thread about this on the cyanogenmod forum.

oh mine was just straight up dead...no download mode or anything visible on the screen (and nothing to do with CM13 either)
hope you get yours sorted out! have you tried reflashing anything via Odin while in download mode?
Its hard to tell you and hard to accept. You can almost give up the hope, your NAND Chip is just what we call " wear-out ". In the most cases no write is possible anymore, the funny part is -> sometimes read is still fine. If that is the case: The system is booting and working, but saving just nothing. The NAND is frozen to its state before it broke.
At our local store, customers come to us with issues like " Factory Reset impossible ", "Can't delete my Files" "Can't create files". All these Devices have inaccessible NAND's and inaccessible Recovery. Only Bootloader is working, but as the NAND is broken, flashing doesn't change anything.
