Hello everyone,
I downgraded the BIOS of an Automation PC 910 from version 1.23 to version 1.22 and after the automatic reboot triggered by the update script, I never got an image signal back. The problem is that the USB ports also seem to be inactive after this restart (no keyboard recognized). When power is given to the APC, the power LED lights up red for a brief moment and then green, just like on a normal startup.
There is no activity from the HDD LED either.
Can the PC be saved somehow or did the contents of the BIOS memory get destroyed after the downgrade?
Last but not least, the procedure went on smoothly and I got the message in the end that the BIOS was flashed successfully, nothing went wrong during the procedure.
I am grateful for any help or feedback provided.
Hardware details:
Board: TS17-00
BIOS: 1.23 downgraded to 1.22
