    Hello guys.

    I have some problems with Lillipop like battery drain, wifi disconnecting and some minor issues.So I decided to downgrade my phone to Kitkat version, but after few seconds in Odin it says "fail"

    I have Samsung s4 - gt i9506 black edition, so Im downloading this sammobile.com/firmwares/download/40605/I9505XXUGNG8_I9505YXXGNH2_ORX/

    Also this is what it says in phone when it fails: secure check fail : aboot
    And here is the log from Odin:

    <OSM> Binary Check MD5.. Do not unplug the cable..

    Thank for you helping me to resolve this problem.
