If you want to continue to try and find a permanent fix, I would focus on the radio related IC's. First of all, today we know that reballing the BB is not sufficient, you have to jumper U1/V1 because those traces crack and will cause searching issues. The normal symptoms are lack of IMEI when dialing *#06# but I would still try this on your device. Then I would reball the U_WTR_RF, U_WFR_RF and U_ASM_RF and see if that helps.
