    How come I can’t get my 4g LTE on any KitKat ROM or jellybean rom? Actually, my 4g LTE only works on stock Roms and certain “semi-stock”Roms? I’ve tried putting in the correct apns in and just about everything, but it only stays on that apn(never obtaining 4g or anything above H+) for a few seconds and reverts to the apn containing “wap.cingular” or just loses data completely… I’ve flash different Roms back and forth and not a single one will work unless stock or “semi-stock” please help…
