My SM-T819 won't turn off, it's stuck at the logo. Fastboot mode is accessible. However, the PC does not recognize it then, so Odin is not usable. Twrp has not been flashed.
Is there a way to revive the tablet?
I have a SM-T810 which does the same thing, dunno why. I recover it by holding the power, Vol Down, and Home key until it comes back to recovery. Then I just reboot. Very annoying. Only seems to happen with unplugged, too.

Hello
i had the same type of problem on my t810 the solution adopted was to let the battery drain
after that you can use the standard recovery mode and do a hard reset

Hello,
I got one S5830, it was locked by wrong pin. I was unable to wipe with recovery because of stucking in it. Vol+/- not working at all. And couldn't enter download mode. So I made jig and phone entered download mode as planned, but after flashing via Odin, it started to blink with backlight and stopped booting. I unplugged battery and put it back. Phone starts with Samsung logo, blinks briefly 1-2 times and reboots again.
Jig doesn't working anymore, just power on phone and bootloops with Samsung logo. Only ramdump mode works.
If I plug it to PC while booting it only blinks with backlight, Odin can't see it, Device manager too.
Is there any way to fix this device without service center?
Thanks in advance.

I can't enter recovery, can't use any other mode but ramdump. Looks like vol buttons works because i can reach ramdump. But if I try to boot other mode, it only blinks logo and bootloops as I wrote in top.
I know it seems strange, normally it would be the other way around, but that's how it is. I used to be on stock 4.1.2 with root and philz touch, I dediced to flash PA 4.6, and everything worked right, but I wanted tot ry other roms as it didn't even have hybrid engine any longer. I turned off my phone, and tried to enter recovery, model from phone flashes and the the screen turns off, recovery screen never came up, the phone was on as touching the capacitive buttons make their light turn on. I pull out the battery and enter into download mode, use heimdall to flash the latest philz recovery I can find and it happen succesfully, iI turn off the phone and go again into recovery mode and the exact same thing happens, screen turned off but phone turned on, go to recovery mode again and yet again, the same thing happens, screen turned off and capacitive can light on.
I can still boot into the rom without a problemand do everything normally, has this ever happened to anyone else?
//EDIT//
So, I don't know what happened, maybe I was using the wrong key combo, but now download mode appears again, the problem is that it's not getting recognized by heimdallr most of the times I connect it, the time it did get detected I flashed philz again, but recovery is still innacesible
//EDIT2//
tried to install a rom using mobile odin(tried to flash recovery but it wouldn't let me) and, bad idea, now I don't have a working rom and it does the same as recovery, stay the screen turned off the oly thing reacting the capacitive buttons.
I noticed that when the phone is turned off, it appears on the computer as an MTP device(though I can't interact with it), when it is in recovery or ormal modescreen off) it doesn't appear at all, when I'm in this mode holding power button for several seconds makes the samsung logo flash a couple of times until it comes back to screen turned off.
also, when running the comman lsusb I get
"Bus 004 Device 105: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]"does this happen to anyone else?
also did this procedure http://stackoverflow.com/questions/6484279/detecting-device-for-debugging-adb-does-not-work, but it didn't help
TL;DR I can only access to download mode, but heimdall is not detecting device(and when I was able to flash a recovery everything stayed the same), recovery mode results in a turned off screen in which only capacitive buttons do something, holing power buttons makes the phone reboot.
I believe i've royally screwed up and i want to know if there's anything I can do to save my phone.
I downloaded the latest BeyondROM from here after being on a previous version for about a year (not sure which one I was on):
https://forum.xda-developers.com/ga...evelopment-exynos/rom-beyondrom-v6-0-t4017921
I flashed the zip file through TWRP and only after flashing did I realize that I was on TWRP 3.3.1-11 and not 3.4.0-3, which I'm guessing is why my phone is now stuck on the boot logo when I boot it. I went back into TWRP and cleared the Dalvik & standard cache again after this but no dice.
But it gets worse. I then tried to upgrade to 3.4.0-3 by flashing it from TWRP 3.3.1-11 using the recovery partition, hoping to reflash the firmware after doing so.
After doing this and my phone rebooting, not only am I stuck on the boot screen, but now I can no longer enter recovery mode either by holding Bixby + Vol Up + Power. My phone isn't recognized by my PC or Odin now either.
Is my phone completely bricked, or is there a way to salvage this mess i've made?
Could really use some help.
Thanks guys.
If you can go to download mode, try re-flashing the stock Samsung firmware via Odin.

Thanks for the suggestion, however that's my primary issue. I can't get to download mode (which really should be recovery mode since I have TWRP).
Do you think it could be an issue with me rebooting to recovery mode after upgrading TWRP using TWRP itself? Maybe my phone needs to be hard powered off once to access TWRP again?
And since I have that failed ROM install, the only way to power off the phone would be to wait for the battery to drain.
Power+volume down+Brixby goes right into download mode bypassing the recovery

My phone just keeps restarting when Power + vol down are held. Looks like draining the battery didn't help either. I'm stuck on the boot screen even when plugged in with 0% battery. When I remove the USB Cable and hold Vol down + Power, the phone seems to turn off because there's no battery, but immediately after plugging in a power cable, the phone automatically turns on by itself again.
You can try this, but best not to flash anything without charging battery first. You can charge while phone is off:
I was trying to go back to stock after having Lineage installed but it crapped out during the install. The tablet is now stuck on the SAMSUNG logo screen and it seems impossible to do anything to get around it. The only button combo options that work are power+vol down which reboots and power+vol down +home which puts it into download mode. I've tried reloading the stock firmware and twrp using Odin but it always results in the same, the tablet reboots then goes to the standard android update screen, says it's doing an update and then reboots and it's back to the SAMSUNG screen. Nothing I do gets me into recovery and while Odin connects I can't get ADB etc to.
Any suggestions other than throw it in a drawer and forget about it?
TIA
Ok I got further. I left the tablet for the battery to die, then fully charged it, plugged into the PC and then started with the recovery key combo and bingo got the No Command screen then the standard recovery options. Deleted the cache and did a factory delete/reset and it's alive again.
Recently i rooted my tab a8 and like a dummy i accidentally flashed the vbmeta and now the device is in a boot loop and pressing buttons doesnt seem to do anything, im just wondering if its bricked?

Try this if the tablet is constantly rebooting. Insert the USB cable into the PC but only partially into the table. When the screen blanks, quickly hold down both the vol up and down buttons and plug the cable the rest of the way in. That should put you in the download mode to re-flash the ROM with Odin.

I have bootlooped the A8 plenty of times and it really is just holding the buttons down at the right time as RamenGOD described. Having the device plugged into the computer definitely can help you get it into the download mode a bit easier. Just saying don't give up, it's not lost.
