Hi guys,
since yesterday i have a weird issue with my samsung tablet. It won't turn on anymore. If I try a hard reset it does not react at all. I pressed The power + volume up as well as power+vol up+ home button for ages. If i try power + volume down it shows a display with
" warning!!! a custom OS can cause critical problems......... Volume up:continue Volume down: Cancel (restart phone) "
I've tried both options. If I hit vol down it just turn black again and nothing happens, if i press the up button the next screen tells me it's in download mode and i must not turn it off.
Since the screen stays on for ages it cannot be an batterie issue i guess. After a while i really did turn it off. But the problem persists.
Another important thing to mention. The day before i installed NordVPN and played a bit with it. Same on my iPad and my iPad had the very same issue the next day. Luckily the hard reset on the Ipad worked right away. It turned on again and i deleted the NordVPN.
Do you have any idea how to fix this, and maybe what caused it.
Thank you very much!!
Your in the S1 section not the S3 one, though what fixes an S1 boot problem most likely fixes an S3 as well, below is the link to the S3 section.
Good Luck.

MY galaxy s2 has problems with powering off every now and then. it was really bad at one point where all it was doing is turning on and rebooting right after. i had a custom rom for months and never had problems until yesterday. i couldnt go on recovery mode because it would always restart every five seconds. Now it seems to less frequent because i realized that it always reboots when i touch the power button once. Sometimes when i push the power button to take it off sleep mode, the power options pops up (recovery, restart, power off etc) so thats when i thought the power button might be the problem
Any guesses on what could be the problem?? If its software problems or power button issue.
P.S. reset my phone, re rooted it, and put a new rom darkside. It literally stays on until i push the power button. then it restarts five seconds later.
the power buttons seems to stick....I have the same problem, the phone is acting as if the power button is being pressed without being let go. When the power button is held indefinitely it just keeps rebooting over and over again. It occurs sporadically, but once it sticks..it sticks. I seem to be able to unstick it by slapping it against my hand but eventually it turns off. Its definitely a hardware issue and I will open up the phone right now to investigate. Ill write if I find anything useful.

I just did a reboot of my tab and it got stuck at what I call "Black Sceen Crash".
Looks like being switched off - but isn't.
It does react on screen touches with a very brief vibration.
And it gets a litte warm.
Does not react on long pressing power button - so no reboot, no download mode, whatsoever.
Guess I have to let it run out of battery - which might take couple of days with screen off. We'll see.
Any idea what to do or what could have caused that behavior? Any similar experience?
Before trying to reboot there was no mobile connection, and I wanted to reboot to get it reconnected. Otherwise no problem.
I am running stock Samsung ROM, rooted, Skyhigh Kernel, OC/UV.

Yeah, I also discovered long pressing power button alone does not force-reset the device. I managed to reset it though by press-hold Power + Home + Either Vol Up/Down. Give that a try.
I can't remember whether it was the Vol Up or Down, try one then the other if it didn't work first time. Good luck.
After a while (30 min probably) it did not any more react on screen touches and was cold. Off maybe? Still no reaction on long pressed Power Button. Tried Volume Down+Home+Power Button - and fortunately it revived the tablet. Strange. Thanks for the hint!
I face the Black screen of death and the device (T805) was not responding to any reboot, recovery or download mode actions, sent it back to Samsung support and they claim an internal piece of HW need to be replaced, I refused that and asked for refund or new device... After a week I got a replacement device...
My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.
Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks
Your welcome let me know how it goes. Will do my best to help.
I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.
How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?
To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.
Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.
Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Hello everyone,
I'm trying to rescue the contacts of a S4 mini with a completely broken screen (just black). I found some post stating:
First remove battery and reinsert, then press volume down, home and power button at once until the device vibrates, release and push volume up. Connect USB and flash the TWRP recovery with Odin. After removing/reinserting battery press volume up home and power. It should be in MTP mode.

As I can't see what happens on the phone I tried it several times but no luck. What happens is:
I press all the mentioned keys until it vibrates and when I release the buttons to press volume up, it vibrates again and a few seconds later the Samsung jingle is playing (I guess this is normal booting). Any idea, what I'm doing wrong?

depends what was causing your blank/black screen. If the cable has come loose then it will not work until it's reinserted.
What caused the black screen? Did you drop it?
Is there any sign of power in the screen? Is the black screen you mention caused by "no power" or "no image", do you think?
If no power seems to be getting to screen then you should take the back off and the inner cover and check the connectors, as first step. But could be other hardware failure (if not software).
