So I recently installed CM 10.1.2 on my S3, and everything worked perfectly for a few days. Yesterday though, my phone started acting strangely (lag when turning screen off, registering phantom input, etc) and began rebooting every few minutes. At some point, it ran out of battery - and now I can no longer boot past the CM loading wheel screen.
I can't boot to recovery, and I don't think my phone is taking charge (from my computer or a wall outlet), and the farthest I can get is the loading wheel - sometimes it only gets as far as displaying the Samsung logo, or the Galaxy S3 screen with the android dude at the bottom.
I'm still covered under warranty, and would love to take it to the store for a replacement (I've had battery issues prior to this), but the fact that it can get to the CM loading wheel means that they might figure out that I've rooted and whatnot. But I can't get to recovery to flash a stock image, so...what can I do?

Your best shot is to either borrow someone's S3 battery or buy a battery pack. Use that to restore your phone back to stock (unroot) and then you can go to the store for replacement.

So turns out battery isn't the issue, I used a wall charger to get it to full charge. I can get it to the download mode confirmation screen, and can press volume up to confirm - but my phone reboots soon after that.
Recovery isn't really possible either, I can see the blue text in the upper right but my phone reboots after that as well.
My phone will often show an empty battery icon with a little refresh icon in the middle; does this indicate that it doesn't see the battery as charged (even though it is)?

Yeah I've been doing some research into the issue...
I've noticed that my phone automatically boots when I put the battery in, and that it'll do a quick vibrate when plugged in to a power source (outlet or computer) but won't turn on.
Apparently the phone isn't supposed to boot automatically when the battery is put in, and this could be the source of the random reboots - I think if I can get the rebooting under control, I'll be able to get into download mode and fix it all. But I'm not sure how to do that. Maybe the power button has gone bad, as it also doesn't usually respond when I try to use it to turn on.
If there is a problem with the power button, does anyone have any ideas on how to fix it?

Mine does the exact same thing where I have to pull the battery and when I put it back in it automatically starts up and when I go to download or recovery it turns off before I can do anything
Sounds like power button issue.
I was having the same issues (random reboots, boot loop, powering on when battery put in, reboots in download mode and recovery)
This is not an easy fix. I ended up pulling the power button out and just setting my screen to time out after 15 seconds. Sucks but it works now.
If I ever need to turn off or hard reboot, I stick a pin in the power button hole and push down on the button.
Really turning me off on purchasing future Samsung phones

The power button is a common issue for these phones.
Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.
Maybe youve got the loose battery connector problem?

What would you suggest I do, submit it to warranty ? Will they disregard the fact that knox has been tripped if its a hardware issue ?

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!
UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....
[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

Wtf
How did you get to that mode? Looks like its trying to flash from the sd card. Ive seen safe mode but not that.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart
Yesterday my phone got stuck in a bootloop (wouldn't go beyond the htc logo screen, recovery was still accessible) after turning itself off (from being too hot I think?). I turned it off via recovery as there was no other way and I wanted to look into the problem now, but the phone won't even turn on anymore. It doesn't seem to charge either (at least the LED doesn't light up).
It's running Android 4.2.2 I think (the latest officially provided) and is rooted. I did not change anything system related recently. The last "noteworthy" things I did were updating a game and "playing" it for maybe 30 minutes (I use quotation marks because I think I left the game running but stepped away from the phone for like 5-10 minutes, but I can't say for sure; it was turned off when I came back), until itself shut down.
The only suggestions I could find for phones that would not turn on or charge were trying different cables/power sockets and removing the battery. Tried 2 different cables on 2 different sockets and my PC; removing the battery it not really possible with this phone...
Any way to fix this?
galaxy s6 won't turn on after being off for 8 months and plugging it in earlier this month. After leaving it plugged in for a while, I came back to see the download screen. I left again and came back and it wasn't turning on. (this was the supposed story, didn't have any issues before it stopped turning on) now to what I have been trying. I have tried to launch into fastboot mode, recovery mode, power it on, basically anything that I could use to turn it on I have been trying. It does draw power from my chromebook and i can tell because when i plug it in the battery estimate jumps way down and when it gets unplugged it jumps back up. I am at a loss because usually I am able to fix tech, but I figured that before I give up I would ask you guys.
Can you boot it into recovery mode or download mode?
If not then the sceen is probably dead this is usually caused by dropping it, if you feel vibrations, sounds or other things it's still working and you might have to go to a tech store to get the screen repaired
Hi. I've got a SMT700 that I purchased new and have used for several years with only minor troubles(Having to reconnect the battery occaisonally) and recently I had a new issue come up I've no idea how to fix. My knowledge on this stuff has extremely large holes in it, so I may have missed something obvious. I've been poking around all week trying to figure it out to no avail.
Anyway, the issue: My daughter was using the tablet and it became unresponsive. I popped the back off and fixed the battery cable(It had come out) and after doing so it flat out refused to turn on. Wouldn't boot in recovery or anything else I could think of. So I plugged it in overnight and let it charge just to make sure, since I wasn't sure if it had had much of one when it turned off. Will not turn on. If you push the power button while it's plugged in, the status of the charge(Says 100%) will blank out and then it resets like I just plugged it in. I've found that if I try to boot it in Recovery, it will come up just fine - if I unplug it, it turns off instantly. If I reset it, it turns off and goes back to the charge status screen as if I just plugged it in. It just has the Samsung firmware installed, I believe fully updated(I rarely check it since the tablet is old and it's literally just used for Disney+ for the kid lately) I'm at loss for what could it causing it or what I can do to fix it. Anyone seen this and able to point me in the right direction? Thanks for your time.
Oh. And I have tried plugging it into the computer, but it doesn't even register as plugged in(Can't do recovery or anything) - that didn't really surprise me, it wouldn't charge that way before so I didn't think it would work.
