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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

Instructions:

• Download the latest build, official TWRP (3.3.0 and newer) and GApps (if you need them)
• Boot the downloaded TWRP via fastboot
• Flash the latest build
• Reboot to bootloader and boot TWRP once again
• Flash GApps and any other necessary add-ons

Migration instructions

Downloads:

• Official builds: LineageOS
• Recovery: Official TWRP
• Google Apps: OpenGApps (nano package is advisable, but you definitely should avoid using stock/super packages)

December firmware can't detect VoLTE IMS registration. So phone won't detect VoLTE outgoing call connected status (No call duration, No conference call and outgoing calling sound still ring in background after reciever connected)

If you are in Oreo now and have never updated to official Pie, follow the instructions on this thread to make a backup of your partitions

https://forum.xda-developers.com/mi-a1/how-to/tool-low-level-backup-restore-unbrick-t3790307

You can exclude System and Data.

If you want to go back just restore the backup and flash any Oreo rom (or restore your TWRP backup if you have one)

Anyone having occasional issues with SIM card not been detected after reboot? There is no dialog to enter the pin. Strange thing this happens every second or third reboot otherwise its fine. I'm on PIE fw

So if I have official lineageos 15.1, should I flash stock pie first? And only then I can flash this one, right?

No need, you can just flash dec firmware and flash this rom, or maybe if you want, you can go back to stock, install all the ota updates, and flash this rom, bcs in some cases, flashing december firmware remove some lte bands, that's why in op flex said don't force update if you don't want more problem.

 

[matheusX]

sir, Could it be that I'm asking for more in the next update can you add the translations?
your ROM was one of the best I've ever used
