blackview_admin, thanks
before flashing 20161216, i would like to know why when i unzip file, the scatter file is "scatter.txt" 1 Ko ?
In other ROMs the file is " MT6755_Android_scatter.txt" 13 Ko ...
Thanks for complete answer, please.

Sorry, I can not tell you. But I once tried flashing and it worked for me.

Answer is important to install TWRP recovery ...

I have no other file that I could give you. Hope it works for you.

Same problem with P2 device !
-> 1h less than display time
Android 7
Build = P2_Blackview_20170619

Why Blackview devs are not able to fix an as simple bug like wrong GPS time ???

Did you try to update to the latest firmware, 20170708 ?

@Parcheval, please
I know what and why i ask this ... Thanks
