This is based on MANNUR LENOVO derived firmware with build.prop optimisation (better video streaming) with FULL GApps and NO Chinese bloatware. First install TWRP recovery on any version A889 then flash the optimised firmware with a second accompanying Update.zip to version S017 both has to be Flash together achieve full compatibility.
Wipe Dalvik-cache first. it WILL NOT delete installed 3rd part apps you have downloaded on your phone , only it will delete the System app. So any PinYin and Chinese keyboard app in the system will also be deleted. You will have to reistall PinYin and Chinese keyboard from Playstore.
To Flash recovery you can either use Mobile Uncle Tool (If your phone is Rooted with VROOT) after the installation of this firmware you will be Rooted correctly with SuperSU+busybox with SuperSU 1.94 or you can use SPFlashtool to flash the recovery from PC.The recovery TWRP recovery is the same for both A880/A889 (so dont be surprised to see A880 recovery)
To get into recovery press both Vol+/- and then Power button or install any "Quick boot"app it should come with Reboot into Recovery" option.
For those without TWRP Recovery use Mobile Uncle Tool if possible to install new recovery for those that cannot use Mobile Uncle Tool use flash tool (scatter file included in the zip file for Flasing TWRP only.

(Maps, GMS Core, Talk, WeChat,)gps,conf file but is currently set to Malaysia change the locale by editing the file instaed of using FasterGPS as it will delete the rest of the settings that should be included in MTK devices.
