G2 D802 has no WCDMA signal - need QCN or baseband topic

SOCIALIZE IT ⇨

Hi,
to recovery my D802 brick,I brought it to a guy to fix it and he used some tools( octopus, JTAG with hardware tool). He recovered the bootloader and up stock rom, recover IMEI. ..
My phone was back, but have a big problem: The 3G signal had gone. He fixed a lot of time( recovery IMEI, upgrade QCN ...)but it only have 3G signal in a few minutes and still gone. after the phone restart, it need manual choosing network, switch to GSM (2G) and after that switch to 3G (WCDMA). Now I have to choose GSM because changeing to 3G will have no signal

My phone is 16 GB D802, import from China market( some software is Chinesse).
Now my stock rom is:
TWN/TAIWAN LGD802 2013/11/30 D80220C
Can someone have the same kind of G2 like me, please use QPST tool to port QCN file for me?
Thanks
