Hello everyone! My Galaxy Tab Pro 8.4 won't turn on anymore. I tried charging it, that wasn't the issue. I left it on the charger and nothing changed. I plugged it into my PC and it didn't make any noises and it doesn't even recognize it as an unrecognizable device. Is there any button combo to see if it's 100% fried or not?

A couple of weeks ago I rooted it and updated it to another ROM, but it had been working PERFECTLY since then! WEEKS!

Any suggestions?

power button
Press and hold the power button for 30 - 40 seconds and see if it powers up. I had this problem yesterday.

Hold the power button down for 2 minutes and don't let go, also hold vol up while doing it to see if you can get into recovery.
keep it plugged into the charger while you do this.

OK, this worked. How can I unroot and restore the OEM bootloader and everything?

Before flashing I made a TWRP Backup, as well as a Flashify-backup.

I have these two folders on my desktop.

to restore everything you will need to boot into download mode , if you are in download mode now you can use kies or odin to flash the stock firmware and this will correct everything.

to boot to download mode its either (Power + vol down) , or (power + vol up) , try both until you see it say download mode., or if you are currently in twrp you can select reboot->download mode

you can get th stock firmware here

And this will remove root, TWRP and any custom roms?

yeah it will be like when you first bought it.

btw when using Odin3 put the firmware under the AP box, don't mess with any options.
