I flash magisk from sideload, to flash from twrp Ive read that you must change slot or flash twrp on both slots.

Pd: stock version seems pretty well, only a few LOS functions are better. Restore wasn't as good as stock (maybe Android q feature?)

Pd: I got a weird audio bug with whatsapp playing from close speaker.

it might be that when you pull down data from a previous backup made with a newer OS version, some incompatibilities rise and so Google's backup & restore operations don't fill in all the cracks like they do on the same version. I wouldn't be surprised if a lot of the newer stuff came with Q though.

as for the audio bug, is it "crackling"? that was fixed fairly recently in a Q update, and may not have been backported to P.

    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.

    It should go without saying, but do not lock your bootloader with this installed. You must be 100% stock, I'd suggest on both slots, in order to re-lock your bootloader. Doing otherwise will likely lead to a brick that Essential really shouldn't warranty.

     * before flashing it! YOU are choosing to make these modifications, and if

    Unofficial LineageOS Builds
    Essential PH-1 (mata): https://updater.invisiblek.org/mata

    Google apps
    Google apps (opengapps nano) are baked in to these builds. This is due to the A/B partition layout and complications backing up/restoring gapps between builds. This is not ideal, and is the major road block to getting this device in to official status with Lineage. At this time I do not plan to release non-gapps builds. Users who require this will have to build their own.

    Device | Kernel
    Here's a local_manifest for those who want to build at home.

    • Unlocked bootloader
    • OPM1.180104.092 firmware - even if you were on this build, you should flash this firmware package to ensure the firmware is on BOTH slots.
    • Fastboot and ADB set up (use your google-fu to figure this out)

    This device is different than what most people are familiar with due to the A/B partition layout. If you're familiar with Pixel devices, then you already know what this means. This thread isn't really designed to explain how it all works, that should be handled somewhere else. Instead, I'll assume you can either follow directions or do some research on your own. Additionally I have a discord set up where there are several people who may be able to help if you run in to a snag.

    The initial install should go rather smooth, and future updates can be taken through the built-in Lineage updater app (yes, the are the seamless updates you may have heard about). Due to A/B, the recovery's ramdisk is actually on the boot.img partition (the rom's ramdisk is on the system partition now). What this means is once you flash the rom, it essentially (lol) replaces the TWRP that you have installed. This shouldn't be a problem since with the seamless updates, you shouldn't have to ever go into recovery. If you find yourself needing recovery, you'll have to re-flash TWRP to get there.

    Phew, now some instructions.

    • See the prerequisites. You really do need these or things aren't going to work for you.
    • Boot into bootloader mode and wipe data with:
      fastboot -w
    • Download twrp (mirror) and flash it with this command:
      fastboot flash boot twrp-mata_11.img
      (no, this isn't a typo, you are flashing twrp to the boot partition)
    • While still in bootloader mode, use vol down to select "Recovery mode" and hit the power button. This should boot you in to TWRP. Enter your previous lock screen password or pin (if it asks) to decrypt your data partition.
    • Put the device in sideload mode with:
      adb shell twrp sideload
    • Install the zip via adb sideload with:
      adb sideload <zip name here>
    • When finished, reboot.
    • Profit!

    The LineageOS team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!

    • FAQ site with some more info (be gentle with the terrible, or should i say complete lack of, css)
    Here's a bunch of answers to a bunch of questions and things I've seen asked about. I'll link this in post 2 so it can be found again easily.

    Halp! My wifi doesn't work!
    Why: This is due to the boot.img being replaced either by flashing TWRP again or some root methods. In fact, it's not even that the boot.img is replaced, but the kernel inside it has been replaced. The problem here is that the kernel you have flashed is checking the wifi module when it tries to load it and determining that it wasn't built alongside this kernel. This patch must be included in order for the kernel to ignore this check.
    Solution: Re-flash the ROM and don't flash any other stuff afterward. Do this to make sure wifi works initially. After that try flashing your mods and see what causes it to break.

    How do I wipe cache/dalvik cache?
    Answer: You don't. Don't worry about this. You don't have to do it. I promise.

    Halp again! My fingerprint reader isn't working!
    Why: Your firmware is not the same version as the blobs included with the rom. Fingerprint reader uses some lower level firmware than what's included with the rom. Make sure you have the same firmware as mentioned in the OP. Firmware available here. You can just download and flash the appropriate "Firmware Package", you don't need a "Full Dump" for this unless you intend to go all the way back to the stock ROM.

    Is there a changelog?
    Answer: No, because I'm a lazy piece of sh!t. You're better off looking at the github history. I realize not everyone understands what a lot of it means, but that's a good excuse to learn something ;)

    Sup with this not getting official LineageOS support?
    Answer: Just a quick response to this. If I felt this ROM was in a state to give it official status at Lineage, I could turn that on at any point. I won't though, due to the A/B layout and retaining gapps/root/etc (addon.d/backuptool) between rom flashes. I touch on this in the OP too, there's just no really great solution for this right now. The same reason my Pixel builds never went official: official Lineage builds can't, and never will, include gapps. My current best solution would be to roll a supported gapps package that would work with the A/B stuff that I had worked on earlier this year. Opengapps won't work with this without a bunch of hackery to their installation scripts. The biggest problem with all this is if you flashed an update that didn't have gapps over one that did, and forgot to re-flash the gapps zip on top of it, android will get super pissed at you. Rebooting to recovery in this state and flashing gapps after having booted without them wont fix it. Its messy and will cause a lot of problems for users. That's the real reason I haven't made a push for official Lineage on Pixel or PH-1. Rest assured, I've been with the CM/Lineage team for many years (if you didn't know this already). This going to get about as close to official builds as you can get without actually being official.

    More stuff:
    - Double tap to wake is not going to happen here. If people want to roll their own kernels/ROMs with this functionality, that's on them. The hacks to enable this on devices that don't support it at a touchscreen firmware level are detrimental to battery life.
    - I'm not kanging oneplus 3teabag whatever device's drivers. If someone wants to roll their own kernel or ROM with stuff like that, have at it.
    - lineage-15.0 is in the works
    - 360 cam still doesn't work. Got closer with some proxy debugging, but haven't nailed it down yet.
    - Built in updater still needs some work. If it appears to hang, it's probably still installing or finished (it does all this in the background) but somewhere along the line stopped updating the notification. I need to track this down still.
    Here are the steps I developed to install LOS and then correctly root it with Magisk.
    I just tried it with the latest 1130 build and it worked perfectly.

    NO NO NO
    Don't ever give out `dd` commands. You will brick people because people have fat fingers and will mistype. At the very least use by-name partitions and not numeric partition numbers. (I've removed the comment, this is a really bad thing to do)

    If you need magisk, flash this after flashing your rom: https://download.invisiblek.org/magisk_14.3_invisiblekhax.zip
    That zip will flash magisk to the opposite slot you're booted to. So you shouldn't have to deal with this reflashing twrp and swapping slots business.
    How to Successfully Install LOS over Stock

    Is LOS 1205 compatible with firmware NMJ51B?
    Thats a good question has anybody confirmed this?

    Yes, LOS 1205 is working perfectly fine when flashing over either NMJ32F or NMJ51B.
    It is very important to back up all your data and then wipe the phone with fastboot before installing LOS when coming from stock. I believe that most of the weird issues people are reporting here after installing LOS is because they did not wipe the phone first.
    Another set of issues is when people try to flash twrp after installing LOS in order to root or flash other things. Since the new A/B system does not have recovery partition like before, flashing TWRP again messes up the kernel!

    Here are the steps for getting phone with stock rom (NMJ32F or NMJ51B) to LOS 1205:
    1) Backup all your data, including documents, photos, downloads etc.
    2) Wipe phone This is important!:
    fastboot -w
    3) Flash twrp:
    fastboot flash boot twrp-mata_6.img
    4) Flash LOS 1205 zip from within twrp (copy zip to phone and install)
    5) If you want root, from twrp go to Reboot -> Bootloader, then flash the rooted boot image:
    fastboot flash boot boot-LOS1205-magisk1437.img
    6) Boot system as normal

    * Rooted boot image: boot-LOS1205-magisk143.zip UNZIP before flashing
    * You will not have TWRP after this process. Installing TWRP again could break LOS.
    * If rooted, you will need to get Magisk Manager apk from magisk thread and install as a regular app (no flashing)
