Notes
Android 7.1.2 NougatGapps not included.
Can be rooted in Developer settings.
Bugs
VPN not working. Solution is to download Shadowsocks and turning on NAT mode.If 3G isn't working, dial *#*#4636#*#*. Tap on "Phone information" and set preferred network type to "WCDMA only". It is recommended that you do not close this menu and just lock the process in the recent apps screen. This is only, IF, 3G isn't really working for whatever reason on your device.
Installation

5. Reboot back to recovery.
6. Flash firmware archive.
