hello grazy excuse the intrusion, I can tell you from experience do not need to re load the bekup full, you need a file ori or mod of the same length or true 2,048 kb (of course with the same codes hw and sw )enter bdm and write only the m58xx so-called flasks once written, the drive will go on the bike without problems , if your bdm if you don't get the item m58perche sie blokkata you can build the bekup externally and then upload it , let me know ,
