You needn't install this patch. All works out-of-box and works perfect.

@snail_phablet ... Before lunch you need to sync Device trees, kernel and vendor from GitHub.com/ubports-oneplus6. Example of path: device/oneplus/fajita

Ubuntu Touch hasn't USB Tethering. Yes, there is RNDIS option in UT Tweak Tool but it used for USB debugging when ADB was unavailable.

@rbhawk It is impossible to install Ubuntu Touch on OxygenOS 10 base, because we are using OxygenOS 9 based kernel. You can just flash OxygenOS 9 to both slots and then, flash Ubuntu Touch.

Installer config merged! Enjoy using UBports Installer.

@opaijavai Hello! https://forums.ubports.com/topic/6446/oneplus-6-6t-installer-config

Hello guys! Now, we have working OTA, recovery and today, I created installer config too. Download link: https://raw.githubusercontent.com/SevralT/installer-configs/master/v2/devices/enchilada.yml.
Small instruction:

• Note: Terminal arguments working only on Linux!
• Download installer config
• Download latest UBports Installer from here: https://github.com/ubports/ubports-installer/releases/tag/0.8.8-beta
• Start UBports installer with the parameter -f </path/to/enchilada.yml>

This config was tested on OnePlus 6T. You must downgrade your Android to 9 version! So, you needn't wait, when it will be merged. You can install it right now.

Hello guys! I installed latest OTA from system-image server and it have no any bug. It have random reboots on suspend mode, but I modified kernel (Nuked CONFIG_PM_AUTOSLEEP=y) and now, system have no any bug. Official OTA's is now stable!!!
