CyanogenMod 10.1 for LG Optimus L9 Is Now Live

While the official Cyanogenmod 9 treatment given to the LG Optimus L9 was a great success, the Cyanogenmod team seems to be in a mood to keep delivering joy to the owners of the mid ranger. This is an official Cyanogenmod 10.1 ROM for the LG Optimus L9 which can be flashed onto your phones via any Custom Recovery.

Cyanogenmod 10.1 or CM10.1 is the latest set of off-market firmware available from the Cyanogenmod team which is based on the latest of the Android platform, Android 4.2.2 Jelly Bean. Although the Cyanogenmod ROMs hold to the vanilla Android interface, they can be highly customizable. Apart from the aesthetics, Cyanogenmod ROMs are also known for their flexibility as they can work upon numerous tweaks at once which can come in very handy in increasing the performance of your device.

If you are done with that, let us proceed with our tutorial.

Pre-Installation Tasks

  1. Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it. Rooted users can use Titanium Backup which also backs up data along with the apps.
  2. Back up all contacts to SD card.
  3. Backup SMS on Android.
  4. Backup call log on Android.
  5. Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.
  6. Remove any security or Anti-virus app if you have them installed.
  7. Enable USB Debugging. This can be don by Settings>Applications>Development and making sure that USB Debugging is checked.
