My tablet was in my bed and I went out. When I came back, it's in infinite loop. Other times this has already occurred and I fixed it.
So, yesterday, I tried to do this. But when I selected "Wipe Cache Partition" in boot menu, the process was taking too long and seemed to be freezed. So I pressed the Power Button and turned off the tablet. After I tried to turn on the device again, but anything happens. No boot, no Download Mode, on the Android Menu. Nothing.
I already put it to charge, tried to connect to PC, but nothing happens (the PC not recognize anything). No screen signal or noise. When I put it to charge or connect to PC, the device warm up to bit.
I already opened the device, checked the battery status, with a multimeter, and did a manual charger. But still, nothing happened. (The battery is OK)
Is there anything that I can do?
I need my device and some files. In my city haven't a place to Advanced HDD Recovery, and the Samsung's Technical Assistance is in the capital.

Do you see any light coming from the screen when booting? The screen could have failed or the light. You can try to take a flashlight and put it on the screen to see if you see any boot animation when you turn it on. It sounds more like a hardware issue.
Have you tried to plug the tablet into a computer? You maybe able to recover the data that way. Samsung might be able to repair or recover the device, but if it is out of warranty you may have to pay for the service.

I don't see anything! I'd plugged into a PC, nothing happens! I think only at Samsung Technical Assistant... But I dont have warranty anymore, so have to pay for this!

The TL;DR is - Running ROM fine. Phone boots up but screen does not turn on. Does not seem to boot into recovery/download mode. adb is attached aka works.
Phone was sitting on desk, untouched and not charging. Now the phone screen does not come on, but hardware keys light up and notifications come on. I then charged the phone for several hours. Hard reset with a battery pull, let it sit for 10 mins, try to reboot. The phone vibrates once, and 30 seconds later notifications come in, hardware lights come on, and led blinks. So the phone is booting fully, but no screen on.
If I try either of the recovery or download combinations, the same normal boot up happens. So I cannot seem to get into recov/download normally. Odin does not recognize the phone. Windows OS recognizes the internal and external storage as normal. "adb devices" returns nothing.
Is there anything you think may solve my screen-off predicament? .... Worst case its a hardware problem Other than that, I am friggin stuck here. Your assistance and suggestions are greatly appreciated!
Had a similar issue when a flashing went bad. My charger was plugged in and for some reason it just kept looping like you mentioned. No combination worked.
I disconnected charger and pulled battery. Waited a few seconds and did the recovery combination. That did the trick. Hope it helps

I am open to suggestions. Plan on opening and operating, as I suspect it's a hardware issue. Worst case, any have experience with replacements?
(Oye, now I'm reviving the OG Droid Incredible ...)
Take it into a pitch black room and look closely, does the backlight try to turn on? I had a very similar problem where my backlight just died, I could see the faint outline of my home screen (like my brightness was on -50% lol) and everything worked but the screen. Ended up being a hardware problem.

Thanks for the suggestion. I cannot see even the faintest of light, just pitch black screen.
It's peculiar though --- the hardware buttons are not vibrating. As if it's not recognizing any input other than the Power Button. And thus, maybe why its not recognizing the volume rocker to get into recovery.
Bump: adb now works and recognizes my device. Open to suggestions!!!
edit: Tried adb reboot recovery ... phone turned off, vibrated, then received no input whatsoever -- however still made the connection noise when plugging into USB. Only solution was a hard reset.
Okay, here is the problem. I have looked around, and this thread seems to be close to what I initially ran into.
http://forum.xda-developers.com/showthread.php?t=2199042
What seemed to cause this was some sort of update verizon was telling me to download, and I kept deferring it until I accidently hit yes. After hitting yes and the update going through, the phone booted to "System software not authorized by Verizon Wireless has been found on your phone.”, which would force me to restart.
If I used odin's button patterns, I would come across the mentioned route in the thread.
But the route I went (because I assumed it would work) is download what was prompted as a "custom os" as opposed to denying it and (I'm assumed based off the thread just posted) starting the phone up. After an hour long car ride, leaving the phone alone and apparently "downloading" the custom os, my phone turned off.
Now what I am facing is only a red led when charging (which is normal when charging while off), but when using any odin button pattern, my phone simply vibrates and nothing more. Nothing on the screen, even when pressing the power button itself. It just stays pitch black. I have no clue what has happened. Any possible suggestions? I tried with battery out, charger in as well as battery in, charger out, and charger in, battery in.
If you plug the phone into your computer and power it on/attempt to enter Odin, does your PC recognize it?

Actually, plugging it into my computer just keeps making it vibrate as if it is starting to power on. I can't even get into odin or even a screen coming up for that matter.
Hey thanks for the help! I figured it out. I guess the battery was incredibly depleted from leaving it in download mode in odin. I charged it up and after a few hours, the power came on. I followed the guide in the thread I posted and it worked like a charm. Sorry about the confusion and I greatly appreciate the help. Thank you!
So today I was using my phone and then i could turn the screen back on. So i pulled out the battery and tried to turn it back on, however it didnt work. I tried plugging in the charger, but there wasn't any orange charging light (it was on around 60-50% battery when it stopped working). I tried connecting it to a pc, but there was nothing, i couldnt access the sd card and there was nothing on the device manager. I tried doing the volume down and power button and other stuff, after a while i managed to get the phone to boot up but it died before it made it to the lock screen (not charging). Is there away to fix it?

Try removing your battery and then plug in the cable connected to PC USB. I would also try doing the same with a unix based system, just to be sure that there are no driver issues(though windows should at least show an unrecognised device in device manager).
Also, can you keep it on charge for some time and see if the phone feels a bit hot...? If not, it seems to be hardware fault.

Maybe your phone is bricked,but the way you explained it seems like a hardware problem !
Do you have warranty ?
Hey so this is what happened.
I use TWRP recovery
I wanted to "completely" factory reset my phone and so I went into recovery and did the usual factory reset And then I went into advanced and selected all the things and did the factory reset
And then I clicked on one other thing there (I think it was the option to "format data") and it asked me to type "yes" if I wanted to do the action and I typed yes.
After this I did a factory reset again and rebooted my phone. It did not go past the Google logo. Then the charge ran out and it turned off.
and now its not even charging (nor turning on) even though I'm 100% sure the charger is okay so it has to be related to this factory reset.
I've tried googling around this thing a little but haven't found any solutions and I know I'm stupid for doing something I wasn't supposed to but urgh! I hope you can help me out. Thanks
(I think its important to make it clear that I can't turn on my phone at all nor can I charge it. Maybe it cures itself in the morning. Thats what I'm hoping for. )
If you selected all the things, as you said, you have most probably erased system partition too. You have to reflash a ROM or restore a factory image. Charging should not be affected, I believe after some time charging will start.
I doubt its truly dead after a factory reset, Hold the power button until it vibrates (20 seconds tops). If that doesn't force restart it then leave it plugged in for at least 30 minutes before holding the volume down and power button for 30 seconds or until it vibrates. Lets say all goes well and it vibrates, you then need to get the factory images as you have deleted your entire system. You will lose all photo, videos and music. (You already deleted them when you typed yes in twrp).

It didnt start. I also managed to kill charging. I think I deleted my phones ability to charge the battery.
I charged my brothers battery on his phone and inserted his battery on my phone. Then I got onto bootloader and flashed the image. and now it works. Cheers

your doubt was well, wrong. I did delete everything including the phones ability to charge.

Wow, I thought I was on the OP3t forum...
Hi! I'd like some help.
I have a Samsung Galaxy S10e (SM-G970F).
The power button is faulty, I got it back from service yesterday, unfortunately it was not repaired because the device is rooted.
Before I handed it in for service, I was able to turn it on without the power button (download mode -> restart), but now the download mode is not available either.
And it doesn't indicate charging either, the display is completely black at all times.
Yesterday the computer recognized it as a drive, but it showed only one TWRP folder. Today, unfortunately, the computer does not even recognize it, nothing happens when the usb cable is connected.
Is it possible that the device has remained in some service mode?
Somehow I would have to reboot or get into download mode, I just don’t know how..
So now:
The display is completely dark.
It does not respond to buttons.
The power button is broken.
It does not indicate charging.
The download mode does not start.
The computer does not indicate a usb connection.
The adb doesn't see either: error '(null)' not found.
What can I do?
Probably is bricked by the shop you leave to repair, get back to them

Thanks for the suggestion.
I can't go back to the service now, I made a complaint in writing before yesterday about this, the investigation time is 30 days.
However, I have new news about the device.
I realized that the device itself works, only the display is always dark.
I disassembled, unplugged the battery from the motherboard, and switched back to download mode and Odin recognized it.
I managed to update the software on it, the device restarted fine, only the display is completely dark.
The computer already recognizes it, I can give a command via adb, and I can hear the volume button when pressed.
The only problem is that there is no picture on the display.
I reconnected the display connector to the motherboard, but that wasn't the problem.
When the power is off, the display does not indicate that the charger is connected.
Does anyone have any idea what else I can do?
Try this command (It toggles the display on and off ):
adb shell input keyevent KEYCODE_POWER
