NEED HELP - Changing band loses the network (KPN)

[Fred Goossens]

I have a HTC Tytn II with KPN network(flexibel) and internet, the problem I have is that I can't change the band rate from GSM in AUTO, when i change it I have no network anymore, so the network is G and not 3G.
Please help me to solve this problem.

ROM 3.29.404.0. NLD
Radio 1.65.16.25
Protocol 25.83.40.02. H

This sounds like a problem I had a while ago. It was an antenna issue. I had to send my TyTN2 for repair in order to fix it.

The symptoms: I could use only GSM in GSM mode. In auto or UMTS mode it kept on searching, connecting, disconnecting. Repeating over and over again. First the Y! -symbol, then the three dots building up (Y...) connecting, displaying 3G-symbol for about two seconds and then everything drops dead and the whole network searching starts again. It was only stable in GSM mode, could not even make phone calls in auto mode.

After calling support they collected my device for repair. Took about a week and a half and it is now fully operational again with 3G/HSDPA on KPN network in NL.
