For the MS45 we have not got any complaints from customers. However if you have got any issue on MS45 please send us original files, and file read after you write using hextag we will compare.

Tried another MS54.1 today. Reads / writes OK as a backup / restore but no comms after on cloned DME (FLASH not written correctly). If you clone one by one, communication OK but has a checksum RAM fault. This fault probably not the tool fault but I did not have time to test.
Thanks again.

possible to send us original file, donor file, donor file after cloning.

Please check faults on car. Try sync cas-dme and check if starting.

..ME9 DME , this one is the worst either from BMW N42 / N45 engine, reading it will corrupt it . Try programming it won't finish setting signature 😏 write internal flash yu brick it, it will never read in boot mode i don't know if there is any solution to this 🤦
