Just bought a korean version g2 the f320k version. Phone works for making calls and sending text messages, but will not connect to their data network. Not sure if its because I do not have the 700 (lte) band range for an option on the phone when I enter the WCDMA service menu. I work for a subcontractor for AT&T and am somewhat familiar with the equipment they use. the LTE radios run off 700. UMTS and GSM is most common 850 and in higher priority areas 1900. doesn't appear that the phone supports UMTS bands either which might be part of the issue. I have done all sorts of tweaking with the frequency bands and that kind of stuff when you enter "5457#*320#" but none of my combinations seem to be working. Ive tried rooting the phone following the exact instructions on the rootjunkie videos, install seemed to have gone good, but root checker tells me i do not have root access, superuser installed during the root process, but something else must be out of date or something. Was hoping to be able to flash the phone with AT&Ts rom or something and maybe that would work. I live in the Minneapolis, St. Paul MN area...has anyone else had any luck with this version of the g2 working on US carriers? I really don't want to, but pretty much ready to give up on this phone, I've scoured this website for the past few days and cannot seem to find any solutions.
Can anyone confirm this phone, flat out, will not completely work in the US market? Please help android gurus!!!
