1 year ago I was able to solve this issue.
Adapter reset over Jumper, boot device with jumper on 3+4, flashed new FW and set Variante to rip again.

Description
Trying to upload a new firmware 8ed9 to my eBUS adapter 3.1, I got the error 'unexpected checksum':

After reboot, the LED is very bright like in bootloader mode but connection no more possible, even when Pins 3 and 4 connected.
