Thank you! I actually had already read that, but as I didn't know the chip number i sort of ignored that. Ok, let me see if i got it:

First, I have no dump, backups or something like this. You are saying me to download that 9.0.43 and flash it? Ok, but my mp4 is very different, it has a 2 inches lcd, and card reader... Can't I kiil my mp4 forever if I flash another fw?

Thank you for your help!
