Version 8.010 is your navcore application.
Western_Europe_1GB_890_4234 is the correct map for your navcore and device.
Make sure you use only the latest version of FastActivate.
Confirm if a .dct file was created in the map folder. If not, the map has not been activated. If so, delete the .dct file and run FastActivate again.
Also don't forget to patch the navcore!
As long as the ttgo.bif file is present in your device before patching, it should work.
Otherwise, you can also try one of the other tools available to patch your device, such as Easy Tools or Albert's Easy Activator.
