  • I am stuck at step 8. Every time I select the jelly bean ROM. It gives me an error saying that installation is aborted. I have a question. When we download jelly bean ROM. it is in WINRAR Zip format. Do we have to extract it? I had downloaded the ROM and just copied it into root folder of my Xperia S. I have used FXP204 unofficial Mango and coconut. Both of the ROMs are giving me error Message. Please tell me if I am doing anything wrong
