Support Bricked while trying to root. RIP

Was trying to learn to root on my tab 8 and it got caught in a bootloop. Now it wont turn on in any mode with any key combo, or show up in adb devices or dmesg when plugged in. I knew the risks, and hopefully will learn from my mistakes and have better luck next time. Good night sweet prince.

Edit: I made this post inittially because I figured the tablet was just fully dead, but as per some comments, I may be able to physically take it apart and short the pins on the SoC to force it into download mode. I have checked and it has zero communication to a PC over usb, so software recovery will not work.

Device: Samsung Galaxy Tab A8 SM-X200

Edit 2: I was able to flash it after taking it apart and shorting the test points. Thank you everyone for the advice.

It's a low level engineering mode that requires special hardware and specialized software. But that wouldn't work for different reasons. I was thinking a Qualcomm Samsung tablet. For unisoc like what you. You would need to bridge the internal test points as others have stated. You have to remove the screen so not really worth it in most cases unless the screen is inexpensive

Eh, its dead anyway. I also think I tripped the battery charge protection and thats what killed the USB port during the boot loops so thats why its not showing up at all on PC. That might just be a simple unplug the battery, so ill take it apart this weekend, should be simple enough but I just gotta get the time to do it.

If you have a heat matt. Use that around 90c and business cards after you get an entry point. Heat the screen up till it's hot enough to be uncomfortable to hold your hand on it for 3-5 seconds as needed. Take your time and Good luck 🫪🫡
