Does anyone else have problems with the processor on this version? Consumption is between 50% and do not know if this is normal
root the phone with kingroot , after that download a system app remover and remove security locker
that app is responsible for processor high ussage,battery drain and over heat
hope helped
also you can flash AOSP V3

does you try this ?
yes all good
Hi! I want to install this from TWRP, but will i lose root if i do?
So I found out that it's not possible to use TWRP for official OTA updates.. Guess I'll just wait for someone to make a ROM based on this.
got up link unpack it find "MT6582_Android_scatter.txt"
Put scatter loading file and click Format all+download!
I had installed custom rom!
works great for me!
What does scatter loading file mean? And where did you format all+download from? SP-Flash?
works grat for me too with official room downloade from doogee.cc.

I personally very poor battery life with this ROM!
Strange battery drains in 8 hours with this ROM ???
Using official rom downed from doogee, battery performance is way way better.
Works a treat and fixes the bluetooth low volume problem. Battery life seems to be better than KitKat as well.
reboot is not working
how to install root ?
KingRoot-4.1.0.249.apk
reboot is not working for me too.
