[Q] Cant use GSM ONLY
I have Samsung Galaxy S5 (SM-G900F) from Ireland O2, i use it in Lithuania with SIM BITE LIETUVA. I can't choose GSM ONLY in settings, why?
With this SIM in other phone everything is fine, but in S5 i can't use it.
I try flash my S5 with ODIN into other country, but ODIN show FAIL, i only can flash with my stock firmware.
So what i must to do that GSM ONLY show up?
*#*#4636#*#* - don't work for me, i don't know why.
