The radio needs the open firmware installed. The official firmware does not support backup or restore functions
Then use the opengd77 CP's to restore the eeprom and flash
Then turn off the radio and reinstall the official firmware using the official tools
You also then need to use the official CPS to reload your codeplug
If you made a codeplug using the Opengd77CPS it won't work correctly with the official CPS, because the Opengd77cps has 80 channels per zone , and the official only supports 16
Also the official firmware does not support assigning a TS to a Digital Contact, or Per Channel power or Per Channel squelch etc
Also if you loaded any DMR IDs , that won't work either as the official firmware only supports 8 characters per ID but the Opengd77 supports up to 16 characters per I'd and defaults to 15 characters, hence the DMR ID data will not be recognised by the radio
