LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), 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. 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.

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 Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Frequently Asked Questions
When you're about to ask a question, read the FAQs below, otherwise it'll be ignored.

Rule: NEVER ask for ETA

Q: Can we port treble to our device?
A: NO, unless OnePlus supports treble in official OxygenOS. Treble is trouble, treble is fake news. From my point of view treble brings zero benefit to the device. You already have countless custom ROMs, treble won't bring more fancy ROMs to the device, it just brings endless trouble to device maintainers. The most important point is, some of our proprietary vendor blobs aren't fully decoupled from /system, so fake Treble won't achieve the same effect as Google announced, especially when upgrading to new Android versions via GSIs.

Q: It VoLTE working on our device?
A: I don't know. My carrier doesn't support VoLTE/VoWLAN, but I've added necessary IMS stack to the ROM, and there're actually some users reported working VoLTE. If it doesn't work for you, DON'T issue me, I'm unable to fix it. Notice: If you strongly believe your carrier does support VoLTE/VoWLAN but the toggle doesn't even show up in settings, tell me your carrier's MCC/MNC number (check

Q: Please add support for sRGB/DCI-P3 as cm-14.1
A: Our kernel does support them, you can enable it via sysfs toggle: /sys/class/graphics/fb0/srgb and /sys/class/graphics/fb0/dci_p3, maybe some apps could help you do this easier. The frontend is WIP(in fact it's already under reviewing, will be merged soonDone)

Q: Please add xyz features or fix UI/UX related bugs/regressions
A: All feature requests and UI/UX related stuff should go to LineageOS JIRA:, I only take care of hardware-specific stuff.

Q: Can you make my device bypass SafetyNet?

Nice work! Gonna install it asap and report any issues.
Device OP3T, not rooted, encrypted.
I list here whatever I am able to find:
  • Charging doesn't make a sound nor vibrate, no matter what settings.
  • Option to switch hw keys light on/off is missing (i know not real issue, but many prefer them off)
  • Display modes missing sRGB, DCI-P3

Thank you! Will install and give feedback after few hours.

EDIT:So far so good. Very good for an alpha. But we should wait for official to daily use i think.

Edit again: Official rollout has been started. Except some kernel issues(fixable with custom kernel), great rom. Okay for daily use, no crashes or random reboots. Thanks anyone who put work on it.

I'm wondering if this is the f2fs loopback problem.
Is your data partition f2fs or ext4?
