Install LeWa OS on LG Optimus GT540
LeWa OS is a Gingerbread Android 2.3 custom ROM that not many have heard of. It combines features of Cyanogenmod 7 (CM7) with the beautiful interface of MIUI for a unique experience. XDA developer Koloses has released a LeWa OS ROM for the LG Optimus GT540, based on CM7.2 and runs on Android 2.3.7, the latest version of Gingerbread. It’s a testament to what wonders the custom development communities can concoct, making the latest ROMs run on a certain phone, even when the manufacturer of the phone says that its hardware is incapable of running even Froyo.

This ROM and the guide below are compatible only and only with the LG Optimus, model number GT540. It’s not compatible with any other device. Check your device model in Settings » About phone.
