Gsm problem

[ultraslan]

Hi,
My phone does not work with GSM network band.
When I change Band from Auto to GSM my phone gets off.
When I change band from Auto to WCDMA my phone works with 3G network properly. I can make voice and video calls. But in auto mode, whenever 3G signal strength decreases, so phone goes into GSM mode and phone gets off.
Many many ROM's I tried, and many Radio ROM's I tried...

My Bootloader Screen :
------------------
Security unlocked

DIAM100 MFG 64M
SPL-1.40.Olinex
MicroP-Diam (LED) v11

PSOC-Diam STAGE_PVT v0x30

------------------

And is this PSOC-Diam STAGE_PVT v0x30 line on the green area in bootloader screen normal??

What is my problem??

Thanks in advance.
