I have an Etrex 30x but when I patched the Etrex the Topoactive maps aren't visible anymore...

Tried to revert back but no luck... It updated the original firmware. But still no activated maps. I guess he set a flag somewhere to lock the maps because of patched software.

Tried resets install new maps...

What can I try?? Didn't make any backup... Yes I know stupid.
