Hello,
I am struggling to update neglected NAC (21.05.78.22) to latest 21.08.87.32, first created by Peugeot Update, then Mittns Toolbox.. updated does not start and shows only error "update not compatible". My idea was that maybe it's too old, so I started to download multiple old firmwares down to 21.06.47.34 but no luck.
I am wondering, can't it be refusing to update because prehistorical maps? Currently it reports 966.7352-prod
Any tips?
