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.

Code:
#include 
/*
 * Your warranty is now void.
 *
 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at me for messing up your device, I will laugh at you.

3rd PARTY ADDONS/MODS
While we have no issues with people using supersu/magisk/xposed/custom kernels/etc, we can't provide support for users who have them installed.
This thread is not the right place to discuss about mods/addons.


HOW TO INSTALL LINEAGEOS
- Make sure your phone is running Oreo firmware (from OxygenOS 5.0)
- Remove custom encryption pins/passwords else decryption will fail!

- Copy the LineageOS zip to internal sdcard.
- Unlock bootloader and install TWRP.
- Boot into TWRP.
- Perform a backup of your current ROM. (Optional)

- Optional: Install the Google Apps addon package. (see Downloads)

At SourceForge (found at downloads link above) we also occasionally provide firmware zips or custom built TWRPs.

We use them when developing and also make them available to others, but please note they are unsupported.
They are good enough for us developing but might not be good enough for everyone's usecases.

@codeworkx is trying to upstream the changes we did to TWRP and created a thread for that, if you need some more help.

Is this pre-official?
Yes, i am one of the Lineage OnePlus5(T) maintainers and this is what you will get, when official nightlies are starting.

Only difference though is, that i am building with "sdclang", official build servers build using the default toolchain.

// edit
to clear up confustion, previously my github and general username was "Evisceration", nowadays it is "amartinz".

Bit off topic, will Lineage get exchange support in the future?, as now its missing in all oreo roms (not gmail with addons)
Forwarded that question, will let you know once i get some answers :)

Yes, there will be more builds.
we put up builds whenever we see fit, means if there are new features or things to test or if more fixes are in.
We do not want to waste people's time with flashing roms when there are no changes at all ;)

Super glad to see you here! I also see codeworkx has already uploaded the TWRP for 15.1 (8.1) and can't wait to try this when I have an off day to mess around with it! :)

Alright, so it seems that it is not on the bringup item list.
It seems CAF did a single commit regarding exchange in 2017 so seems not a high priority for them as well.
And the people who usually worked on exchange are not active since some time, so it does not look promising.

Seems everyone is shifting focus to gmail or other third party apps.

Thanks for your warm welcome :)
I hope you do not run into troubles that you need the whole day and can actually also enjoy it the rest of the day ;)

@Evisceration What is yours suggestion for root ?
I personally use the built in root via adb.
Magisk should be fine but it annoys me when i have to reflash it everytime when i flash a new kernel.

That Kingoroot thingy from china seems really suspicious to me and i would not even touch it with a pole.

Though, use whatever you see fit, I provide some limited support helping out to get stuff running if someone runs into troubles but my support time is not infinite :(

Ok, thanks for letting me know, i use the exchange/email package from CM/Lineage 14 and its still fully functional.
As for root: SuperSU-v2.82-201705271822 still the best.

Do you know when the migration from 14.1 to 15.1 will start? Tom is running beautifully but I'm missing so many features.
You can best follow the current development state by having a look at the Code Review.

Many features are in work, listing some below as example


so these i found with just having a quick look at the review pages, took me 20 times longer to write this than actually find it ;)

Things simply take time, but are processing good.

glad to hear! :)

i am encrypted though, modifications like removing encryption etc are not tested by us.

I did a clean wipe, format data, then flashed rom with 8.1 unofficial pico gapps and 15.2 magisk. When i boot up, the phone boots back into the recovery. Using the 8.1 recovery from the OP.

Any ideas?

Great work! I'm very happy to see this! Downloading...

ROM might be unified with Oneplus 5T in future (not sure yet).
Is this supposed to say "OnePlus 5"?

Questions:
  1. What's the status of Privacy Guard?
  2. I assuming we're currently encrypted with keymaster1. Will be be migrating to keymaster3 at any point in the future?
Thanks!

Just flash rom and gapps, reboot and setup device. Then reboot to recovery and flash root.
