No stranger to using Liggy Dee's auto fw, but just tried updating AD-5540A with 201bt_rpc1 and 201_rpc1 (not at the same time) and flash has always been successful. No errors at all. However, I don't get DVD region tab at all and players are coming up with digital protection issues. Flash back to default 2.01 and region tab is back.
Strangely 201.7z doesn't have auto. I notice that the 2.62fw has 262bt_auto, so just want to double check if it is ok to update default 2.01 drive to 262bt_auto for auto?
