All the source code for LineageOS is available in the LineageOS Github repo.

Making a new thread so as to not hijack the build thread from March. Until the official release, I will upload weekly builds as I can. I personally test my builds for a couple of days before I release them, but...

USE THEM AT YOUR OWN RISK. I TAKE NO RESPONSIBILITY FOR YOU BRICKING YOUR PHONE.

Builds:
lineage-19.1-20220808-UNOFFICIAL-guacamole.zip

lineage-19.1-20220731-UNOFFICIAL-guacamole.zip
lineage-19.1-20220725-UNOFFICIAL-guacamole.zip
lineage-19.1-20220718-UNOFFICIAL-guacamole.zip
lineage-19.1-20220711-UNOFFICIAL-guacamole.zip
lineage-19.1-20220704-UNOFFICIAL-guacamole.zip
lineage-19.1-20220626-UNOFFICIAL-guacamole.zip

Recovery:
CRDroid recoveries

Recommended Gapps:
NikGapps-full-arm64-12-20220222-signed.zip (w/ Pixel Launcher disabled)

Recommended GCam: (courtesy of Saikat from the OnePlus 7 Pro XML telegram channel)
SGCAM V25 Snapcam_Special.apk
𝚂𝚊𝚒𝚔𝚊𝚝_𝙵𝚊𝚗𝚌𝚢_𝐕4_𝗕𝗧🟢.xml
libgcastartup_8.4_saikat.so

Notes:
  • Gapps packages are finicky with A12/LineageOS-19.1. If your phone hangs on boot after flashing, it is likely a problem with your gapps package.
  • Pixel Launcher is completely broken in many A12 Gapps packages. It will crash on boot, and even if you use a different launcher, Recent Apps will be broken. It's a known issue https://issuetracker.google.com/issues/204650736. I recommend not installing Pixel Launcher at all (and I have disabled it in the NikGapps package I link below).
  • Depending on the last build that you flashed, you may have to switch pre-device from OnePlus7Pro to guacamole in META-INF/com/android/metadata


Flashing Instructions:

First time installation (clean flash):

  • BACKUP YOUR DATA
  • Download latest CRDroid recovery (download). Do not use the magisk patched recovery for initial flash (we will add Magisk later).
  • Reboot to Fastboot
  • Flash the boot.img in fastboot
    Code:
    fastboot flash boot boot.img
  • Boot to recovery
  • Factory reset
  • Reboot to recovery
  • Sideload LineageOS ROM
    Code:
    adb sideload lineage-19.1-20220626-UNOFFICIAL-guacamole.zip
  • If you don't want Gapps, then boot to system. You are done.

    If you want Gapps:
  • Reboot to recovery (DO NOT BOOT SYSTEM YET)
  • Sideload Gapps package (recommend using NikGapps with Pixel Launcher disabled: NikGapps-full-arm64-12-20220222-signed.zip)
  • Code:
    adb sideload NikGapps-full-arm64-12-20220222-signed.zip
  • Boot to system

    If you want Magisk:
  • Only do this after you have finished installing ROM and Gapps (if desired), and successfully booted into system.
  • Reboot to Fastboot
  • Download the latest magisk patched ROM from (download).
  • Flash the patched boot.img
    Code:
    fastboot flash boot magisk-boot.img
  • Boot to system
  • You will have a Magisk app now and can open it to fully setup Magisk


Update from previous build of LineageOS 19.1:
  • BACKUP YOUR DATA
  • Boot to recovery
  • Sideload LineageOS ROM
    Code:
    adb sideload lineage-19.1-20220626-UNOFFICIAL-guacamole.zip
  • If you had Gapps, reboot to recovery
  • Sideload Gapps package
    Code:
    adb sideload NikGapps-full-arm64-12-20220222-signed.zip
  • Boot to system
  • Flash Magisk boot image again, if you had root.

Download link to your ROM navigates to the NiKGapps package.

Can you fix the download link?

Unfortunately I still get an error even after editing the metadata to ensure pre-device is set "guacamole".

Error applying update: 21 (ErrorCode::kDownloadInvalidMetadataMagicString)

Any idea on how to resolve this?

Double check that you didn't add any whitespace to the metadata pre-device setting. ROM seems to be working fine for others, so I'm not sure why you're getting that error.

Everything seems to work, including on Verizon. Used core Nikgapps and flashed fine, no issues. Will test run it throughout the day tomorrow and report back on any issues. Thank you!

Trying to uninstall some of the pre-loaded apps via ADB like Camera (using Gcam instead), Recorder, etc.

However using the below command doesn't work for some reason:

adb uninstall -- user 0 com.android.camera2

Any reason why? This command usually works using other roms.

I am using previous build of los 19.1 which is lineage-19.1-20220316-UNOFFICIAL-guacamole along with mindthegapps package.
Can I dirty flash this new build with the same gapps package, will it support?

Edit: Tried it failed and bootloop to recovery. Back to the old build. Followed all instructions, no idea what could've went wrong???

Yes, it's possible to upgrade from the 03/16 version.

You don't need to wipe cache. Signature verification warning is expected for Unofficial builds. Not sure what you mean by Init user0 failed and clean flash rom.

Follow the instructions in OP exactly for upgrading builds. Generally bootloops or hung boots are an issue with the Gapps you are flashing. Try flashing the same Gapps you had previously.
