Hi, Guys, i'm a newbie here and i didn't know much about cellphone flashing etc., before and just got my fido z710i phone about a week ago and after some intensive reading of tutorials and guides for a few days i managed to convert it to a w710i without having to pay someone else to do it. Now I was looking at this file in the download section "W710_R1GB001_MAIN_NAM_1_CH_RED49" but I can't figure out which region it's for. Is this for North American region? Vietman? If someone could please clarify this for me I would much appreciate it. Thanks. I was thinking if this file is for North American region maybe i could download it and keep it for if I ever wanted to go back to z710i, also i don't see another NAM_1 files for the FS part of the firmware, which FS file could be flashed in conjunction with this main file? Thanks in advance!
