I have run into a problem during the software update of my AFS 4000s.
The problem sequence is:
Backed up system to SD card in advance of update.
Shut Master switch power.
Installed SD card with v8.8.12 files on.
All in the root directory.
Applied mains power, and a series of error messages showed on the screen.
As listed in the photo.
I have left the EFIS running for 30 minutes or so without any change.
The very odd problem I am faced with now is that the EFIS will not shut down at all.
I have turned off the master switch. Result no change, the screen stays on running on battery back up.
I have pressed button 2 for well more than 5 seconds and the EFIS will not turn off.
Your advice and assistance would be appreciated.
