I just got my Galaxy SII 3 weeks ago, everything was good until one day I received a notification saying that if I want to install the new software update for Android. I was on fl22, I press yes and installed and at night I realize I have not received any Emails ( have a small business, so I always get Emails) and when I check my phone 4g has an X, and so I thought that maybe I have to reset the phone so I did it, turn phone back, and the same 4x meaning no 4g network, I pull the battery off for 2 min. and still the same, I have no apps installed besides Facebook, So I call Customer Service and bla bla bla, no help, I update prl,profile, and I did notice that I was on the fl24 which came out on January 2013, so still nothing... so I decided to root my phone and voila!!!! 4g is back
, and install the pacmam jelly bean rom and no issues, so I decided to do a test, so I went back to stock (no root) using Odin and see if I did something wrong the first time, so phone went back to stock and again 4x no internet
, only when I root my phone or install a different rom I have 4g ...BTW 3g never work and I am in a good 4g 3g coverage. so I don't know if any of you have this problem or know the solution because I really like stock. sorry for the sea history, any help will be appreciate
