[HELP] rk3368 - MTCE_LM_ - PX5 -- MAPS.ME Problem

[Hercules8]

I have the problem that the APP "MAPS.ME" doesn't work anymore with the latest update after starting it all remains black, according to MAPS.ME it's due to the change of the engine. I currently have an old version where I have always copied the newest cards into it, this is no longer possible. How to fix the problem?

Edit Off:
it's offtopic but I don't have a radio either so I opened the device and saw that an antenna cable is loose, can someone tell me where it belongs?
