Looking to install a custom ROM on your Huawei P9 Lite? This page lists the custom ROMs available for the phone, with a short note on what each one offers and a download link. Because Android is open source, developers can build their own versions of the OS, which is why the P9 Lite has a good choice of them.
The P9 Lite launched in April 2016 on Android 6.0 Marshmallow (EMUI 4.1) and was later updated to Android 7.0 Nougat (EMUI 5), running on HiSilicon’s Kirin 650 chipset. Custom ROMs are the way to run a newer version of Android on it.
Before the list, here is the difference between a custom ROM and a stock ROM.
What is an Android stock ROM?
When you buy a new Android phone, it comes with a stock ROM, also called the stock firmware. This is the operating system the manufacturer preinstalls, with the features they chose to include. If you want more than that, a custom ROM is the way to get it.

What is a custom ROM?
A custom ROM is a version of Android that developers build from Google’s open-source code, replacing the one that shipped with your phone. It includes its own kernel, so it is a complete, standalone OS. Developers usually strip out the carrier and manufacturer apps and add their own features, so you get a cleaner build with more control.
Community ROMs are updated regularly, with bug fixes along the way, and they often let you run a newer version of Android than the manufacturer ever released for the phone.

Best custom ROMs for the Huawei P9 Lite
To install any of these, you first need TWRP recovery on the phone. Once TWRP is installed, you can flash a custom ROM or other mods. Here is the guide to install TWRP recovery on the Huawei P9 Lite.
With TWRP in place, you can flash any of the ROMs below. Not every custom ROM is stable enough to use as a daily driver, so read the notes and pick one that suits you.
LineageOS
LineageOS is the community successor to CyanogenMod. CyanogenMod was discontinued at the end of 2016, and its developers continued the project as LineageOS, which is now one of the most widely used custom ROMs.
LineageOS on the P9 Lite comes with a customizable status bar, theming, a resizable navigation bar with color options, quick toggles, and more. Follow the link below to install it.

These include status bar and lock screen customization, theming, and the DU navbar/Flingbar, among others. It is stable enough to use as a daily driver.

FAQ
Do I need to unlock the bootloader and install TWRP first?
Yes. Unlock the bootloader, then install TWRP recovery, and only then flash a custom ROM.
Will installing a custom ROM erase my data?
Yes, flashing a ROM wipes the phone, so back up everything you want to keep first.
Do I need GApps?
Most of these ROMs do not include Google apps, so flash a matching GApps package right after the ROM, before the first boot.
Can I go back to the stock ROM?
Yes. You can flash the official firmware again at any time using the guide linked below.
