So far no luck, will try to put the original password.dat file back and see if it makes a difference.
but please keep your suggestions coming.
if it fails is it an options to create a dump out of a F930 (all the directories etc) and then copy it back on the F940? (my other car has a F930 radio)
EDIT:
Just tried the Original file which contains the password but it does not even ask for a password.
I even checked the log files, as far as they are written in several directories, but no error or what so ever.
the weird thing is sometimes after rebooting I get the question if I want to set a password, and if I say I want to the keyboard is disabled,...
I also though I saw 2 files in the NAND/SYSTEM/SECURITY directory, but their was none before I copied the password.dat file.
I cant remember the name of the other file.
could someone create a dump of their F940 and provide me the files?
Kind Regards
