NEED HELP！ GTI13Ultra Bios Recovery

Carl233

Today I updated the BIOS on my GTI13 Ultra to version T204. The previous version was T202.
After completing the update, the system no longer boots properly.

It powers on and continuously reads from the USB drive (the USB LED keeps blinking).
After around 30 seconds, a DP signal appears (but with a black screen), and the keyboard receives power (its lights turn on).
At that moment, the USB LED becomes solid and stays that way for another 30 seconds, after which the system shuts down and reboots in a loop.

I tried recovering the BIOS by using AMIBOOT.ROM on the USB, but it clearly didn’t work.

Is there anything else I can try to recover the system?

Carl233 Hi there,please send us a picture of SN on the bottom of the PC.
Did the computer fail to boot only after the BIOS update was completed?
If the update process is interrupted by a power outage before completion, it may also cause the device to become bricked.

Beelink CS-Jane The computer was working properly before the update, and during the update process, the computer automatically shut down and after that it can’t boot properly. Image description
