All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Wiki.
The LineageOS 17.1 reovery is recommended
If you still want to use TWRP never install the TWRP app as system app. Otherwise your device won't boot
Current lineage 17.1 shamu nightlies are based on the N6F27M October 2017 update from google.
So you should be using the radio and bootloader img from that update.
Before you flash a bootloader or radio image please boot to bootloader and check what you have currently installed. You might already have the right one and don't need to flash it again.
They can be extracted from the factory image on google's site here.
Or you can use the ones linked below that I already extracted:
IMPORTANT NOTE FOR VERIZON USERS: Google released a separate October 2017 security update (NGI77B) just for verizon users that has a different radio. So you'll want to flash it. I repeat, THIS RADIO IS JUST FOR VERIZON USERS.
You can use fastboot to flash the bootloader and radio.
More information and installation instructions can be found on the LineageOS wiki here.
Google apps: Opengapps Use an ARM (not ARM64) package for Android 10
HEADS UP: When you initially install LineageOS, be sure you flash the gapps package with your ROM. If you boot your ROM, then go back and try to flash gapps after, you're gonna have a bad time.
