[Q] How to edit ROM to re-enable APN Settings (ISW13HT - KDDI HTC J)
I have a rooted ISW13HT (HTC J by KDDI in Japan) and I can switch to the HK radio for traveling overseas and unlocking the sim, however for mobile operators who require an APN, it doesn't work in the default ROM. For whatever reason, in the default version of the ROM (I'm still running 2.05.970.3) there is no option to edit the APN and it seems that KDDI has probably disabled it as it seems to be included in every other ROM version that I read about or tried. Currently when I travel I'm loading the HK ROM and using that since it has APN settings but this is far from ideal and I would like to just use my home ROM 100% of the time. I have to use the Japan ROM at home because of the Osaifu Keitai (Felica) function which seems not to work on other ROMs, or at least the Mobile Suica refuses to work on the HK ROM saying that the OS isn't supported and that is an essential function for me to use the train everyday.
I'm sure there has to be a way to edit the KDDI ROM to re-enable the APN Settings function, could someone lead me through this or point me in the right direction. I've tried searches and nothing turned up for me.
