Hello,
I have the same problem, my receiver Amiko HD8260+ show in display error ASH.
I use "Amiko Hd Tool Box 2.6", but the PC cannot view receiver via COM port with RS232 cable. The COM port is not disable on PC.
When I try to make communication with receiver from menu "Upgrade Tool", return to me this:
Open Serial Port..
Sync to serial port..
Target not connect or target is error status!
When I try to make upgrade on receiver from menu "Upgrade tool RS232", after "Test serial post status" return to me this:
Transfer data failed.
Click "Back" to try again.
Click "Cancel" to exit.
Regards.
