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!!!

Installer config merged! Enjoy using UBports Installer.
