Install Android 2.3.5 Based Custom ROM On T-Mobile LG G2x [How To]


t-mobile-g2xJust a while back, the Android 2.3.5 firmware was released for the Nexus S 4G and while that came out abruptly, RootzWiki forum member roman has managed to release this firmware for the T-Mobile LG G2x by using the latest CyanogenMod nightly commits to come up with a custom AOSP ROM named Trigger 2x. According to the him, the goal of this ROM is to add G2x specific functionality / features / fixes to CM7 along with some user customizability.

Credits to Cyanogenmod & Team Douche, faux123, Whitehawkx & Krylon360.

So what does this ROM have to offer? Let’s take a look into it.

  • Based on Android 2.3.5 from the newest CM commits to the github.
  • 1080p video recording.
  • Pre-rooted.
  • Custom, hard-reboot option added to fix data issues.
  • Touch to focus camera.
  • Clock options added: Hide, am pm, small am pm.
  • Signal options: Hide, show dbm text & more.
  • H icon instead of 4G.
  • Optionally install Bloater to download extra GPS configurations to make it lock on super quick.

The ROM does have a few bugs to it such as:

  • A typo in the camera menu when changing front / back cam. Both are named Back.
  • A2DP Bluetooth is not working.
  • CM7 bugs.

You can also catch a few screenshots of the ROM courtesy of roman.
