Problems with 8210

[Josdevos]

Got a 8210 that has always worked perfectly on all 3 belgian networks. I sold it to a friend and he can't find his own network. In manual mode it finds the 2 other networks.
He returned it to me, and now even i cant find my own (same as his) network. With simcards of the other providers get network, but not as strong as in my new 6510 & old 5110.
It finds network on single 900/1800 network but can't find tha dualband network "Proximus".
I already tried to update faid, clear provider locks etc....
What should/ can i do, i have f/m2 bus datacable, already checked for providerlocks etc.
