  1. hello it is saying that you need to have adb v 1.0.32 or higher to sideload this device.please help me

    1. Make sure you download the latest version and install ASUS and Intel driver as well. I won't recommend one to switch tos custom ROM from original. I am suffering and missing the ZenUI.

    2. Maybe you're trying to revert to lollipop, Don't do that, you must sideload the kitkat version. I experienced that problem when I try to sideload the lollipop frimware

  2. It says device not found..what should i do,?

    1. Did you follow all the step correctly? If yes, then maybe its because the usb drivers are not installed correctly, check if your device is properly connected first, type "adb devices" if you found your device then you're good to go

  3. Its saying install first 4.3 img.. Wat its mean

  4. what is the password for unzipping the dowloaded file

  5. can i direct revertback to lollipop rom ? from cm13 ?
