Finally we found the tutorial How to Install CyanogenMod 9 CM9 Android 4.0.4 ICS custom Firmware rom update on Motorola Defy Plus. Motorola Defy+ Plus is a rigid Android Smartphone from telecom giant Motorola. They have done pretty fine with this phone but we are not much impressed with battery. The phone is totally water and dust resistant. For people who work on very dirty atmosphere or keep throwing and dropping their phone here and there can go for this phone. Recently, XDA dev forum member has launched Android 4.0.4 ICS custom ROM for Defy Plus and it is not official yet still in beta stage. This custom developed ROM is based on CyanogenMod 9 which can be installed manually, most of the things are working. Being based on AOKP this ROM is fast and performing nice with battery as well.
