I have rooted my phone through an app Kingroot. Root checker and android terminal says my phone is rooted. I downloaded a custom rom miui for my phone which was a zip folder and put it in my sd card then I accessed android system recovery and did factory reset and wipe cache partition, then applied update from sd card but it says installation aborted!!!!!!!!! Why is this happening? I know my phone is rooted and the custom rom is indeed for my phone. One thing I didn't understand is why there is no option "install zip from sd card" in my system recovery? Are "apply update from sd card" and "install zip from sd card" same thing? Please help me because I'm desperate to use custom rom.
