Hi, I have a 4.2.2 Rooted Stock Rom running on my T-Mobile S4 at the moment (been rooted since June and never upgraded to any ROMS since root was still fairly new to the phone back then), and I was looking at all these ROMS and I want to upgrade to Wicked, Avatar, or XTREMEPERIA S4 ROM...BUT I'm pretty sure I need to do something before I do that. I already have ClockworkMod Recovery v184.108.40.206 installed, and I read in one of the ROM threads that I need to install a MK2 modem or something? I'm lost and I don't want to ruin my phone :/ I already backed everything up using MyBackup Pro, and using ClockworkMod.
Here's some information about my phone that will hopefully be helpful:
Baseband version: M919UVUAMDL
Kernel version: 3.4.0-440244
Build number: JDQ39.M919UVUAMDL
Please help, I really want to use the awesome ROMS I listed above.
Thanks in advance.
