  1. I’m doing exactly as the article says. I’ve installed CWM Recovery. Placed both the files in the SD card. When I try to flash the ROM in the .zip format after wiping data and cache, I can’t install it. It says:
    E:Error in /sdcard/ *.zip
    (Status 7)
    Installation aborted.

    Can you help me with that?
