Success on Avic-F40BT
First I tried to backup my German languages files wit Condis Hack 2.21...
No good idea, stuck on Bootscreen.
Deleting PRGx.flg doesnt help.
Flashed Pioneer version update 4.01 and unit works again.
Made a SD card with 2013 EU update and Voice directory with the needed voice file inside.
Flashed.... All ok, no Voice Files lost
Thank you, small donation on the way ...
