[Completed] please help me to solve network lok on my all ne au isai lg v31 (japan)

i want to unlock the sim of my phone, details are as below....
AU ISAI LG V31 (JAPAN) android smartphone..
Hardware and software info are as below

HARDWARE VER: REV.1.1
IMEI NO: 35447XXXXX61208

SOFTWARE VER: LGV3110f..
my relative from japan has purchased lg g2 previously which was sim locked. so he bought a unlock code for couple of dollars and unlocked it.
.
to do that, you need to find a hidden menu in which u will be able to insetr the unlocking codes(may be by pressing #* and number combinations)
.
*but in. au isai lg v31. we can not find that hidden menu in which he code is to be fed. i have searched and came to know that hey have remove that part in an firmware update.
.
so one solution is that we downgrade the firmware and buy code and insert it. or we root it. (i dont know, whether rooting solve problem or not and i also havent found perfect solution to do that)
.
*or we might check on internet that which is the latest update available for au isai lg v31 and check is there that hidden menu present in that firmware or not
