[ROM][7.1.2][OFFICIAL][WT88047] LineageOS 14.1

[nicknitewolf]

LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.2 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Supported Firmware:

Downloads:

wt88047: https://goo.gl/FNbbMP
wt86047: https://goo.gl/YHufVo

Note:
It is the firmware LineageOS supports and all users are expected to be on this very firmware. So it's mandatory that you flash this firmware via TWRP if you're newly installing Lineage.
You don't need to reflash this everytime you update you LineageOS build.

To add on:
There seems to be some confusion with this post in general. If you are coming from a stock MIUI Lollipop build, it is highly unlikely that you would need to update your firmware with the one above since Xiaomi hardly updates its firmware on older devices. Otherwise, if you are not sure what firmware you currently have, I urge you to flash the firmware linked above.

Why should I even flash this firmware?
The simple answer is that this firmware is known working with LineageOS builds and I am currently running it. Running other versions of the firmware (Like the Kitkat firmware) may warrant unheard of bugs and / or bugs that have been squashed long ago.

When should I flash this firmware?
This firmware should only be flashed once, anytime before the first boot into LineageOS.
