After a clean installation, 829M of space is occupied on /system partition.
Repartition zip with 1Gb of space on /system
For flashing this zip is required to install chrono kernel

Ah, can you post a last_kmsg here?
I want to check the log to see something prevented the boot.
Go take it in TWRP file manager, it should be in /proc/last_kmsg or last_kmsg2...

Some bugs that i found:
- cannot access app menu by using middle button,
- cannot switch to dark theme,
- internet issues; I can ping other devices in my local network with terminal; ifconfig shows that phone get ip adress on dhcp set on,
- cannot get USB-VBUS to work; in Los 15.1 i can't it get to so maybe i'm doing something wrong,
- backlight not turning on when control buttons are used,
- some graphical glitches - icons are teared.
- camera app disappeared: some kernel modules don't load properly (?).
And pic:

This is caused because no button is preconfigured to show the app menu. Wait for next update.

Yes.

Didn't you see "not working" list?

You didn't turn on "USB-VBUS Power" in ChronoKernel Settings. But in this build there is no root access, so we can't enable it.
wujekbrezniew said:
- backlight not turning on when control buttons are used,
Click to expand...
Click to collapse
This is because there is no settings menu for configuring buttons. See your first problem.
wujekbrezniew said:

This is normal as this build is have many problems.

Again... Read the OP.

Sensors (magnetometer, orientation)

For me the orientation is working... I can rotate my screen.
IMEI is not showing on *#06#.

Try to start rotation second time, it will stop working (as far as I can tell, SensorsBox shows such behavior). Apparently, there were some changes to sensorservice, though, I didn't look at these.
I know about IMEI not showing, to fix we need a libsecril shim lib (which, I believe is not very urgent compared to other issues).
