NT EVO ID6 PROBLEM

[audiomeca]

thanks for answering

Yes, I tried to recover the backup with featureinstaller, but there is no option to recover, having been updated to version 11 23 542 the backup was deleted, which supposedly from what I have found out is saved inside the head unit,

I don't understand very well why if the feature installer patch is deleted then it is impossible for Insta to re-import the original FSCs, I don't know what is corrupted for this to happen

I think it will be necessary to make the head unit virgin, but I don't know how to do it, I have very little experience with BMW, but with other brands like Mercedes and Vag

Thanks for your time
