Have here this 6250, where the owner did mapo update, but was on WiFi, and not finished OK. After unit restarted itself, and now is near dead. Logo only, nothing more. When I connect to PC, then = its funny = 6250 open like standard two HDDs, I see one with 0,97 MB, and second with 14,2 GB, booth are empty. MyDrive not see the unit. Ive tried find CAB file with navcore on Google, to try save into small memory, but no luck. Finded only TTPKG file, which after unpack, and saving to memory, not return back 6250 to live... Have someone experiences?
