Solved! Multi Prog Can’t Write Jeep BCM 2017 (R7F701034) D-Flash

Problem:

Xhorse Multi Prog can write to cflash. Only reads but not writes to dflash of processor. Customer has synced and updated 5 times,

Marked it in red in dflash, it does not say write while cflash does. When reading cflash customer changes it to dflash but the icon for write does not appear.

What could be the problem?





Here is the Solution:

Users need to pre-process d-flash data before loading it into Multi Prog Tool.

Load and write d-flash files on ‘MCU>>REBESAS>>RH850>>R7F701034’.



Done! Hope this helps!
