This time, don't hold any button, let it reboot to Linux!
=== Nonfree-userland (halium) installation ===
[[File:Samsung-klte-android-running-inside-lxc-cut.png|400px|thumb|right|Android processes running inside lxc container]]
To make full use of nonfree-userland intallation, which involves running Android in lxc container to make all hardware work (read more at [[Hybris]] wiki page), you need to to '''manually''' download and install custom device-specific Android/Halium system image. Building it manually takes a lot of time and free space on HDD, so I've prepared prebuilt image: https://androidfilehost.com/?fid=6006931924117913010
You need to download it, un-sparse and place in to root of userdata partition:
$ simg2img halium-klte-2019-07-09-system.img halium-klte-2019-07-09-system.img.raw
If it says "invalid sparse format or header magic" it means that the image is already unsparsed. Proceed to next step
Reboot phone to TWRP recovery and push image using ADB:
$ adb push halium-klte-2019-07-09-system.img.raw /data/system.img
Boot to a running postmarketOS system and login with SSH using [[USB_Network]]. Next commands are executed on the phone. Make sure that you have a <code>/data</code> mounted (check output of <code>mount</code> command). Ensure that Android is fully running inside an lxc container (on device, install <code>htop</code>, run it and switch into tree mode by pressing '''t''') (see the picture on the right). If it does not, check if <code>lxc-android</code> is running (see output of <code>rc-status</code> command). Run '''logcat''' and see if it is printing some error logs on the screen.
Before (re)starting lxc-android, remember to remove file <code>/tmp/lxc-android-once</code> if it exists.
