If you had followed EVERY step in the clean install tutorial, your device would be working without errors. But when you start copying maps from other working devices and copy pasting them into other devices, of course it won't just work. In this case you need to delete all .dct files from the map folders and run FastActivate again. Also you must remove the mapsettings.cfg files from the map folders - this often stops the rebooting loop.
I assume you have the North_America_2GB_895_4438 map. If so, this map is available here with the meta too, so you can proceed with the tutorial.
The meta.txt file can be copy pasted directly to the root of the device or SD card, but maybe not necessary if running the latest version of FastActivate.
Therefore, always run the LATEST FastActivate version. Instructions are found in the FastActivate thread:
So please follow the instructions step-by-step, without taking short cuts. These tutorials have been made easy to follow for a reason, and if followed precisely your device will be like new again with the latest map(s) possible.
