So I was running rooted stock IMM76k, and 4g was solid and stable and switching from 3g to 4g was fast and smooth. Then I flash AOKP build 37 over top of stock rooted 4.04 and for some reason the phone drops data and switching from 3g to 4g is a lot slower. I check the Baseband and it says (I515.09 V.FC04 / I515.FC05) Which is the lastest radios. So is there a reason why this happens? I love AOKP and all the options it has.
