STEPS OF DOWNGRADE LOLLIPOP TO KITKAT VERSION WW Hey all many of us facing some problems in lollipop 5.0 and despertaely want to downgrade to the previous  version i.e. kitkat ..let me share u the steps how to do this manually for those who dont know how to do it, The following is a detailed guide with step-by-step instructions to help you downgrade your ZenFone 5. Keep in mind that this tutorial is for the ZenFone T00F and T00J WW variants which should be running 3.23.40.52.  Do not try these on any other variant. Downgrading using the official firmware does not void your manufacturer's  warranty, but you need to be extremely cautious, during the process.
