Unlocked signal problem?

view story

http://forum.xda-developers.com – I just unlocked my lg nitro hd and i either have no signal or 1-2 bars, rarely 3 bars. I also have to search networks and register on t-mobile everytime my signal is gone. Signal always goes out in about 2 mins and Wifi is working fine. Network mode is set at LTE / WCDMA / GSM I'm running cyanogenmod 9.0 Baseband-V10j I also resetted it to stock and i still get the same signals. When i slip the sim card into my nexus one, i get 4 bars. Any solutions? thanks (HowTos)
