XHORSE Multi-ProgProgrammer can force unlock BMW CAS4 5M48H successfully if the simple chip unlock fails. Next, I’ll demonstrate both unlock operations.
1. Simple Unlock
BMW >> BMW(IMMOBILIZER) >> CAS4-5M48H-R/W-UNLOCK >> OK >> Unlock
Already backup the Dflash & Pflash? OK
Chip unlocking failed! Error code: 00000084 command number error.
In this case, we can try the Force Unlock method below.
2. Force Unlock
Reselect the option:
BMW >> BMW(IMMOBILIZER) >> CAS4-5M48H-FORCE-UNLOCK >> OK >> Unlock
Maybe lost data, continue? OK
Unlock success!
Now go back to the original option for a test.
Read ID success.
MultiProg can also read the D-FLASH chip data successfully.
Quite easy.
