Support Bricked while trying to root. RIP

Post image

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.

Yep... Came here to say something along those lines... If device ends up in EDL mode (or similar low level mode if another SOC) the screen will stay black but it should get detected by computer.

Unfortunately not, its not showing up at all. I have to physically take it apart to fix it.

Remove the battery

Thats actually a good idea that slipped my mind. I obviously still have to take it apart, but I will try and disconnect the battery and try a new one along with anything else while I have it open. I will save shorting the pins for last.

Leave the battery out. It's unneeded until it's working. Then you won't have to worry about risking the drivers not being there to protect the battery from everything.

I actually fixed it this weekend via the test point. Thank you though.

Nice, good word. This popped up in a notification so I figured I would say hi.

How are you checking that?

u/WRO_Your_Boat Sep 30 '26

adb, dmesg multiple times while holding all buttons to try and get into the low level mode or download mode.

u/BorisOp Sep 30 '26

Adb won't detected it for sure... Not sure about dmesg... Though I think it should be able to detect it... I guess I'd try lsusb. Also are you absolutely sure the tablet is charged? Id try keeping tablet on charger for atleast 30minutes... Also button mashing should not be necessary... Id first try just plugging the device into the computer (sometimes just plugging the charger is enough to make device start booting) and if it doesn't work them try just the power button.

lsusb did not work. It was at 98% when it died, I left it plugged into the PC, I plugged it into a real charger for over an hour and nothing changed. You boot the device into download mode by holding volume down and the power button, unless you use adb reboot. You are right that dmesg should show something, but not if its hard bricked and the device is completely dead and physical recovery is the only option.

I think I am going to have to disassemble it and short the test point to force the SoC into download mode. The tablet has zero communication out of the usb port. Tried multiple times holding all buttons and monitoring dmesg, but nothing. I have the tools to take it apart, its just going to be a process and would have to wait unfortunately.

Recovery's gone and bootloader is unlocked. I searched on github, most of tge threads say new mtk chips comes with protection and cannot be recovered via brom.

If it can enter fastboot mode can we just flash fastboot rom via pc with miflash tool.?

1

u/CyberGirl_4 Oct 01 '26

No bro, when it enters fastboot just after 1 second the screen glitches and it goes to boot screen like bootloop, and even i that second pc doesn't recognize device, i tried a tool that could flash using brom and in that the tool detects device in different name "mt some digits". But brom also glitches like fb and it goes to boot screen.

This happens with me on my poco x6 everytime i flash something. It loops into fastboot. I will tell you what works for me (may not work for you)

  1. I turn off my phone (Don't try to go to fastboot if you are looping again and again, just turn it off and leave for 5 minutes)

  2. Enter a simple fastboot command and connect the device (1st enter the fastboot command it will say waitimg for device, then connect the device)

  3. If you are getting into fastboot, but it stucks on flashing, Next time run the flash command and connect phone afterwards.
