This is the STOCK ROM of the Doogee X5 Max Pro, do not try to install on another device or model.
It is the latest update sent by Doogee on February 17, 2017, with Android 6.0.1 and the improvements of battery and audio that came, is the most complete and perfect ROM.
To install use any version: TWRP x32
I want to upload it in Needrom servers, be patient
