Full read can be done with any cheap tool, in this case MPPS clone.
Boot mode is useful for immo of.Immo data are stored in flash, but in a protected area of memory, so immo of file can be written only in boot mode.VIN Nr. address is 8000.To decode the VIN Nr. need BMW VIN to Hex sw.Both type of ECU, mean EMS2000 and MS5150 can be made immo off.MPPS original tool can do checksum.Also Kess, and maybe other tools.ECM from AlienTech can do it also.
Bootpin for MS5150 in attach.
Read in Bootmode with MPPS clone can be done also?
And do I need to calc checksum if I just want to FF the ISN to be able to sync immobilizer with BMW tools again?
I'm asking because I want to change the EMS2K from a preLCI Cooper S to a MS5150 from LCI to be able to flash the GP1 Soft with Winkfp
Edit:
Found out that SMOK UHDS is able to read and write Eprom and Flash via OBD. Still the question, do i need to correct the checksum if i just edit the ISN? Will Ultimo do this job? Last time i loaded a MS5150 Full Flash into it said no checksum correction needed
Edit2:
At which adress is the ISN located and how much bytes?
