First time posting on this forum, though have been a long time follower on this fantastic site.
I seem to be stuck at a problem with my new Beelink GT1 Ultimate that I attempted to upgrade with a AtvXperience firmware S912, though in hindsight from reading on this forum it appears to have a S912b chip that is not compatible with this firmware.
I was using the USB male-male and Amlogic USB burning tool to attempt the upgrade; v2.0.9 to be exact.
First attempt it 'crashed' after having selected 'erase bootloader', though when unticking this and retrying it completed successfully.
Then trying to boot it up on the tv nothing happened, and after that it does not even get recognized by windows anymore.
I managed to hook up a UART serial connection to the board and its evident that the bootloader have been corrupted during the process as it keeps restarting at BL2.
I tried to use the BurnCardMaker and burn the latest available Beelink to the SD card and tried to boot it with the (toothpick method), though nothing appears to be happening on the box when monitoring it on the serial connection (keeps looping as usual).
The serial connection monitoring is showing the following on repeat:
