I have the 4.2.2 rooted, and I'd like to upgrade to 4.4.2, is it really as simple as just getting a 4.4.2 ROM? or are there any other things I need? I'm sorry I'm pretty new when it comes to android stuff, it scares me really the thought of accidentally getting a $700 paperweight.
baseband version is M919UVUAMDL
kernel version is 3.4.0-453951 se.infra@SEP-133#1
build # is JDQ39.M919UVUMADL
OK so an update. I guess I literally don't have any idea what I'm doing, I just spent about 2 hours reading around here and honestly couldn't find a single guide or even where to start on how to do this, install a custom rom or anything. I seriously regret rooting and wish I could just do this OTA...... the root benefits do not outweigh what i'm expected to know to upgrade now
Hello friend, do not be discouraged. Do you have access to a PC? I sure hope so. First things first, download the latest version of TWRP recovery, it's great. Flash it via ODIN in the PDA slot. Okay now you have a good new recovery, now you need the latest baseband. What you need to do is download the NB4 baseband before you do anything as far as getting a ROM. There are tutorials in the general section of the T-Mobile s4. You're going to download the modem, flash it via ODIN by extracting the zip and placing it into the phone slot of odin(the tutorials are way better at the steps then I am) then flashing, and then you'll be on the newest baseband(modem). Then you need to find yourself a ROM. Thess can be found in the Android development section of the T-Mobile s4. I personally recommend Insane Kitkat. But find one that you like... I hope this helped friend. Let me know.
Edit: if you're not sure how to get to any of these things, Google them! Google NB4 modem T-Mobile s4, Google TWRP T-Mobile s4.. Etc.. It's easy!
Edit edit: here friend, links
