I follow the tutorial, but the fastactivate did not working bacause write an error (Not network connection - but it's not true).
I have do it update many times, im not beginner...i try albrets easy activator and itw work normally so its ok, do it anything (patching etc. )
but i start the gps, and send an error : Problem with maps, i do not use the map with this device: Eastern_europe-552.

So tell me whats wrong?
Thanks in adnvace!

Please use the latest version of FastActivate as linked in the 890 map thread.

THANKS!!!! Excellent!

So I assume it is all working now and you made a proper backup?
