Anyone please help me I rooted my phone and then used xblast tool to change default background. In this process I changed my build.prop file. And it was working fine until I copied the original backup build.prop file. Now my micromax mad a94 won't startup. It gets hanged on mad logo. Please help me I don't know how to flash new files although I have stock rom.
