• Reboot to Recovery
• Backup any important data
• Format Data partition
• Wipe Dalvik, Cache and System
• Flash the ROM

• Reboot to System

2. If you're updating the ROM or performing a dirty flash:

• Reboot to Recovery
• Flash the ROM
• Wipe Cache
• Reboot to System

You might also want to follow LineageOS' installation guide, but make sure to use the correct one for your variant. Link guides to d855's.

OTA installation
LineageOS updates are full installation packages. That means you can always install only the latest update, even if you skipped some in between.

Performing OTA update on your phone.
Make sure you have supported recovery installed, such as LineageOS recovery that can be found here in this thread. If there is an update available for your device, click Download and wait for it to complete. You should now see something similar to this:

If you'd like your recovery to be updated alongside your ROM, click on the meatballs menu (right upper corner) and select Preferences as shown on the screenshot:

As you can see, there is an Install button. If you are ready to proceed, click it and confirm the dialog by pressing OK as shown:

Your phone should now be updating. It will reboot to recovery, update the OS and boot back to it.

Update blocked: This update cannot be installed using the updater app. What do I do?
This means that the update you are trying to install is a newer version of Android than what you have currently installed on your phone. In this case, it needs to be flashed manually on your device, since Updater simply can't update you to a newer version of OS. You get the idea. If you find yourself in this situation, simply follow the second instruction (so-called dirty flash) posted under Installation section in the main thread.

You are great, thank you..
The second beta release is awesome. Everything seems as it should be. Animations are very smooth. I wonder what is next.

 

[LZ_]

Horrah! just downloading...

 

[jork_C]

thank you for your hard work!

 

[HardStyl3r]

You are great, thank you..
i wanna submit my very first impression after a few hours of use. i had no problem during installation and in general everything is ok. animations were laggy at the beginning but they are smoother now after a while. i am sure things will get better soon. thank you very much again for your efforts.

-google drive crashing, google chrome cannot see the google account so cannot start sync.

-magisk 20.4 does not work but 21.1 beta works.

These bugs are related to the GApps, these are very shady but the basics work. I am waiting for @walter79 to respond and I'll build our own GApps.


Thanks for the feedback.

D855 32gig: came from 17.1, flaweless install, all works perfect, no lags or hassles. Nice work, will be my LOS from now on! Thank you HardStyl3r for this ROM.

 

[fefe128]

and what Gapps can I install for LG g3 D855?

I installed and want to switch instead of Lineage recovery sleep on TWRP recovery. How ?

The setup wizard is tricky this time. It automatically replaces TWRP with LineageOS Recovery unless you uncheck the option. To bring back TWRP, use flashable ZIP in my TWRP thread, flash it (either adb sideload or sdcard is fine) and skip the signature check failure.

Good news on the LS990. installed and booted up fine. Data and telephony both working. Rom seems just fine. Still have my twrp . No fc and no reboots. Can't get magisk 20.4 to flash so no root yet but as smoothly as it's running so far we're looking good. Thank's for the LS990 build.

Update !! Found Magisk 21 and installed root. Works fine now. One question about setup manager related to installing lineage recovery. Is it a onetime setup question or will it ask this on future updates and or resets ? Just wondering if it's something we need to be on guard against . Possible to disable the feature ? Fortunantly I happen to catch it and uncheck it so I'm good. Thanks

LS990 users you can install this . The old reboot problem we had with lineage 17 is gone. This runs good enough I'm going to continue with it as daily driver for now.

This should only pop up when you clean /data. As far as I know, Setup Wizard only appears on first boots, which includes clean /data. If you've unchecked this, I think you are safe. Enjoy. And yeah, the latest Magisk beta works.

 

[LZ_]

Fixed: took the latest Magisk-v21.1.zip, then run the TWRP-App and installed .bin file. Enable Advanced restart and all works fine again!

Why can't I find Advanced Reboot option? Someone enliten me!
