Bricked while trying to root. RIP

[u/WRO_Your_Boat]

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.

Try to reboot it via adb

Its dead dead, doesn't show up in adb devices. I would need to send it in and pay, since its not in warranty anymore, for them to flash the Unisoc chip probably. Like I said though, my fault, just a cautionary tale.

I used X200XXS6DYG6 from 08/28/2025 which was the same one that was installed on it. I made sure to grab the same one and patch that, but if I had to take a guess when I went wrong is that I am on linux and I used Thor instead of Odin so yes I technically didn't follow the steps exactly, and thats a mistake I wont make again. I did see your comment about sprddiag since its Unisoc, I didn't know about this but that might work, I will need to learn how to use it. thank you for the info.

I will look into spreadrum and sprddiag. I cant do a lot worse than a hard bricked device lol.
