then I'll explain what to do in case of a blockage,then NEVER and co NEVER switch off the ignition,exit the program, reopen it, and try mode recoveri to write the file to ori,if you are not going to do other attempts, never turn the ignition off,maybe try without data if it is possible,in case if you have other programmers try with those,in the case of a negative before disassembling the unit, disconnect the positive of the batt for about 30 minutes and then try again if it doesn't there is no alternative or programmers official if anyone in the area or unsolder in the case of edc15 or bdm in the case of edc16.
