MetroPCS (lgms330) and the T-Mobile (lgk330) models.​

The TWRP method: It's easier than the old method in post 3 which did mess up a couple of peoples phones for some reason. The method in post 3 is still relevant for those who don't want to use TWRP for whatever reason.

You will need:

computer, usb cord, and *adb/fastboot installed

*A note to those who don't know what adb or fastboot is:

There are plenty of tutorials out there explaining how to install and use adb and fastboot.

If you are unfamiliar with these tools you may want to check out this forum.

Part 1: enable developer mode / unlock boot loader

Developer options

On your phone, open settings do the following

Enable Developer mode

Enable oem unlock (LG was nice enough to enable us to unlock our bootloader from the "developer options")

[IMG="Allow USB debugging by tapping "OK""]https://app.box.com/shared/static/3et2q78kgchkrst22jgw9ivyitb77oby.png[/IMG]

Plug your phone into your computer and run

you will be prompted to Allow USB debugging?[IMG="Allow USB debugging by tapping "Always allow from this computer" and tap "OK""]https://app.box.com/shared/static/zufaasxpc8f44ae8axxoq1l62aol5rn1.png[/IMG]

Part 2: installing the Team Win Recovery Project.

I can confirm that the following technique works for the T-Mobile k330 too.

Abridged quoted instructions from this thread / partial copy from post #42 Senior Member: starkly_raving

Prerequisites:

1. unlocked bootloader

2. knowledge of fastboot commands.

First, connect your phone to the computer and run

adb reboot bootloader

Next, if you want to test but not replace your recovery

fastboot boot Twrp_m1_v2.img

Instead, if you want to replace your recovery partition with TWRP

fastboot flash recovery twrp-image-3.img

DOWNLOADS:

New forum has a version of TWRP with a button combination to boot into recovery.

Beta1:

twrp-image-3.img I hope you don't mind me mirroring [MENTION=805681]reemobeens19

Part 3: Installing SuperSu, Xposed framework, and Xposed installer

At the time of this writing these are the latest versions:

Xposed framework: sdk22/arm/xposed-v86-sdk22-arm.zip

Xposed installer: XposedInstaller_3.0-alpha4.apk

SuperSU: Version 2.76

Xposed uninstaller <- You need to flash this in order to completely uninstall the Xposed framework if you don't want it anymore or you want to upgrade with a newer version.

On our phone booting into TWRP can be done with the physical button combinations. If you don't feel like doing finger gymnastics you can use

adb reboot recovery

Tap install, choose the zip file(s) you downloaded, and the rest is fairly self explanatory.

If I made any errors or omissions feel free to mention it. I really hope this helps.
