We have upgraded firmware to OOS 12, so there are some changes with flash procedures.

If you are on OOS 12 based nameless build, and there's no WARNING about firmware change or something, you can simply update via System Updater.

If you are on old nameless build / any other custom roms with OOS 11 based, or firmware update needed for new update:

Use MSM tool to go back to OOS 11 (Better back up your persist.img)
Update to latest OOS 12 in System Updater
Unlock your bootloader
Download rom zip, extract payload.bin, then use payload_dumper to extract imgs from payload.bin
Reboot your phone to fastboot mode
Open any terminal like cmd etc, enter directory where your imgs are located, then enter following commands:

fastboot flash boot boot.img

fastboot flash vbmeta vbmeta.img

fastboot flash vbmeta_system vbmeta_system.img

fastboot flash recovery recovery.img

Reboot your phone to recovery mode, click "Install update" -> "ADB Sideload"
Download copy-partitions script from here
Back to your terminal and enter directory where copy-partitions script zip is located, then enter following command:

adb sideload xxx (xxx means the filename of script zip you downloaded)

Wait until it finishes, click back arrow in recovery, then click "Advanced" -> "Reboot to recovery"
Click "Install update" -> "ADB Sideload"
Back to your terminal and enter directory where your rom zip is located, then enter following command:

adb sideload xxx (xxx means the filename of rom zip you downloaded)

Wait until it reaches 47% progress, click back arrow in recovery, then click "Factory reset" -> "Format data/factory reset" -> "Format data"
Click back arrow in recovery, then click "Reboot to system"
