LG Optimus L3 E400 Gets MIUI Port Based on CyanogenMod 9

The LG Optimus L3 E400 does not have quite a lot of developers working on it since the device is new and hasn’t gained much attention. The CyanogenMod team paid some attention to the device and developed a CyanogenMod 9 ROM for this device which is still in nightly stage. It has been like that since months, hopefully it will be stable as soon as possible. A developer irberserk at androidworld.it forums has developed a MIUI ROM for LG Optimus L3. It is based on the aforementioned CyanogenMod 9 ROM and hence all bugs that exist in CM will exist in MIUI ROM. MIUI is a customROM developed by a chinese team and is also a popular custom ROM just like CyanogenMod.

If you manged to install CWM on your device, you can flash this ROM easily.


  • After turning off the phone an restarting it, you might see the battery image. You need to long-press the power button to get past that and reboot successfully.
