It's been a little while since we did a nice Custom ROMs roundup, or top 5. We've broken them down a bit more, so instead of just having LG G2 ROMs here, we're doing those just for the T-Mobile G2, and we'll do the other variants as well very soon. The following ROMs are in no specific order, but these are some pretty nice Custom ROMs for your T-Mobile LG G2.
Team Gummy ROM
Team Gummy is pretty popular in the Custom ROM area. This ROM is built from AOSP, and has some status bar mods, the theme manager, some hardware key and lock screen mods as well as performance control, application permission controls, carrier label options and more. Remember if you are looking to install this ROM, you'll need to flash the Gapps as well, or you'll be without Gmail, Google Play, and many other Google apps.
4.4.2 KitKat BAKED
We all love Team BAKED ROMs right? Well they have a nice KitKat ROM for the T-Mobile G2. As expected, it's built off of AOSP, and does have plenty of mods inside. It does have a navigation button color picker has been added. Additionally, they have made the USB tethering option work as well.
Smasher X is a newer ROM which is based off of CyanogenMod 11. Which is KitKat, so you've got a ROM that's basically built off of AOSP. They've added all kinds of features like Pie Control, Multithemes, playerpro, pc remote, pop up browser and youtube, dolphin browser and more. They've also removed a lot of CyanogenMod's features like CMAccounts, CMFileManager, Apollo and more.
Here's a non-AOSP ROM for the LG G2 on T-Mobile. This one is much cleaner than the stock ROM on the G2. It is pre-rooted with the latest SuperSU, it's de-bloated taking out most T-Mobile and Google apps, it does maintain all the LG features and most LG apps, it's zip-aligned, Busybox, init.d support, performance and battery enhancements and much more.
This is a stock modified edition of the LG G2 ROM, it does support both the T-Mobile and AT&T version of the G2. They've taken out Carrier IQ, enabled tethering, removed lots of bloat, deodexed, superuser, rooted, and plenty of other features in the ROM as well. It's pretty lightweight as well.
