Questions about putting T-Mobile Rom On my I337
Ok. so after being with AT&T since 1998, I went to T-mobile and activated an account today. Last night I also did the mod enabling all the T-mobile AWS, HSPA & LTE bands on my AT&T Galaxy S4 and it was a success. Everything works great, I already have the T-Mobile Sim card installed, and T-Mobile LTE and HSPA is very fast.
I've been flashing ROMS, Kernels and radios for several years on many many different phones and tablets, However this is the first phone I've delt with, with a locked bootloader and also the first time wanting to use a different carriers ROM. The phone is already rooted, with TWRP recovery and I'm running CM 10.2.
Should I flash a T-mobile radio and ROM now that I plan on sticking with T-mobile. If I do, can I flash any T-Mobile based rom, and TWRP will automatically Loki Doki it or whatever it does lol? I don't usually have these questions, but this locked bootloader crap really sucks. The phone is only a month old, so I don't really want to buy a T-Mobile version when I got all of T-Mobile's bands working.
