I have 2508B console with datacode 1a. It has 3.56 firmware installed!
Sucsessfully, i have downgraded it to 3.55 Rogero with E3 flasher.
Manual says, that i need to downgrade again it to 3.41 OFW and than i can update to any 3.55 CFW.
Ask: Can i downgrade it, if factory firmware is 3.50?
Can i downgrade from 3.55 Rogero to 3.50 OFW and than to 3.55 CFW
Sorry for mistakes
