Help with SIM unlocking LG G2 LS980
I'm new to flash/root/unlocking and a need a bit of help. I have been spending 3 days straight trying to SIM unlock my LS980 so i may use it for t-mobile. I followed the instructions listed here: http://androidfannetwork.com/2014/03...lg-g2-for-gsm/
and manged to basically complete the process. Only to find out that for some reason i could not delete telephony.db and add a t-mobile APN. Which means I need to start all over from scratch. Some one told me that using stock ROM wont work since I have a "branded" phone (whatever that means) so must use custom ROMs. But I dont know where to find a proper guide. Anyone with any links to a good guide for SIM unlocking a ls980 using custom ROMs? Thanks so much for helping this noob out.
