When I boot an AOKP ROM I get no signal. I read that you had boot into Sense ROM (not the Stock ROM an Nandroid) and update PRL/Profile from there. That is what I did, I am still not getting any signal. I am on Ting, an MVNO of Sprint. I usually get two bars at most. I have firmware 22.214.171.1240 if thats correct. Gije.
