Take SSD board and any additional memory from old board and transfer to new board, put new board in MFP, D093 will pop up but ignore, enter service mode and set softswitch 07 to HEX 9F and fix. Power down remove EEPROM from new board and replace it from old MFP board (small chip with 8 contacts). Power up, MFP will back up data and you should get a DF31 when complete.(softswitch will revert back to factory setting) Power off. If you get a HDD error, D093, format HDD in service mode. That should do it. Emujo
