Hey,be sure to have everytime a copy of your original
FEC_DB AND
rpkpsh4.bin Backup.
in first place you should restore your FEC_DB and your rpkpsh4.bin. You can delete the line which deletes the rpkpsh4.bin. So it would look like this:
Bash:
del \mmc7\FEC_DB
copy \SDCard0\FEC_DB \mmc7\
copy \SDCard0\rpkpsh4.bin \mmc8\
echo >\SDCard0\restore_ok
del \SDCard0\pase.bat
you place this line in a pase.bat file in the root of your SD Card together with your backuped FEC_DB and rpkpsh4.bin. Afterwards you insert it in the Navigation and do a reboot of the unit (press three buttons at once - you know which?). To restore the backup you dont need to enter the red menu. The Activator from Enthisast, already patched on first run your system, so it makes it possible to run a pase.bat from sd card when the system reboots.
Now you should have the original State of your MMI. I think you should first make sure to get this state, afterwards i can help you further to unlock
