@Seeed_Seraphina I’m facing the same issue
- Downloaded https://downloads.raspberrypi.com/raspios_arm64/images/raspios_arm64-2022-01-28/2022-01-28-raspios-bullseye-arm64.zip
- Installed driver; for some reason they updated my kernel too
cd /tmp
git clone https://github.com/Seeed-Studio/seeed-linux-dtoverlays --depth 1
./scripts/reTerminal.sh
- Before:
L5.10.92-v8+ - After:
6.1.21-v8+
After reboot, still no screen.

I thought I also try flash the display, but it won’t work:
- Comment line in config
- Reboot
- Test
$ i2ctransfer -y 1 w2@0x45 0x9b 0x01

Whatever I do, I can’t get the dislay to work again.
I’m also confused why your script would move the kernel from 5.* to 6.* even though it’s not supported. Reported this on Github here.
EDIT: Tried again

EDIT
So, this is funny.
Out of options, I dissambled the device to check connections; Of course everything was just fine; Pulled-out the battery for a sec; Put it back together. Boot … Working.
Why?
Did that reset something?
