AUtel IM608 XP400 BMW FRM3 Chip is Locked Solution

 Problem:

Hi to all. How I can sort BMW FRM3 module with autel im608 xp400? It is a BMW E90. Thanks for any help.

Error: Chip is locked and cannot be read. For write, erase unlock first. 

Solution:

IM408 will read Dflash under Programmer option, you should first write partition. 

Here is the instruction: http://blog.obdii365.com/2021/11/25/can-autel-im608-repair-bmw-frm3-module/
you can also read dflash with vvdi prog or xprog, orange 5 or UPA.
When you read dflash you need to upload here to extract eeprom. https://tlvps.tomvanleeuwen.nl/frm/ then write back eeprom to frm partition.
