Customer question:
I have a Volvo xc90 2004 need to do AKl. I've read the 28F400 flash from CEM in BDM with SMOK JTAG, made a new chip, id 48 with Xhorse vvdi2. It wrote the file back successful, put everything back but no crank, only fault code in CEM it's related with the transponder. Anyone did this car successfully with vvdi2?
Here is the solution:
You can do them all by reading eeprom, then writing it to a super chip. Don't write anything back, all of them worked.
Customer feedback:
I've sorted. JTAG for some reason swaps the bytes and before you use that file you need to swaps the bytes. Then I did a super chip with Xhorse vvdi2 and started the car. Without writing anything back, thanks for your help.
