Managed to build boot.img and recovery.img, flashed them using AndroidTool.
ADB finds my device:
gytis@desktop:~$ adb devices
List of devices attached
P5CLE90HKP device
But when I boot to recovery, there is no output in HDMI
gytis@desktop:~$ adb reboot recovery
gytis@desktop:~$ adb devices
List of devices attached
rockchipplatform recovery
So either TWRP doesn’t work or doesn’t output anything to screen…
Edit: I was using sources from Rockchip to build TWRP. Now I tried TWRP sources by Khadas team - with latter build succeeds and TWRP works 
Since Kodi is not bundled into Android Pie build, any idea how to build Kodi for RK3399?
I tried running Kodi from Google Play store - it stutters on 4K
Have you tried the custom firmware I made?
Kodi is working smoothly if you setup the resolution whitelist in Kodi Display Settings and enable ‘On start/stop’ in Video Playback Settings.
But I would suggest to use the latest version from here since they fixed H265 seeking and it includes the latest improvements.

Hello! I don’t have Edge, but I’m wondering, when playing a video, does the frequency and resolution automatically change?
Yes, if using my firmware.

this is good ,since on vim3 these nuances can’t be done on Android,for this reason I watch videos exclusively on coreelec, where it all works perfectly 
Will there be a new security patch release for Android 9?
Is “Android Device Policy”
possible with this release?
Our firmware does not contain this APK. You can install it yourself.
This is a Google App. It can be used, but whether it can meet his requirements or not can only be verified and tested by himself. After all, there are so many functions.
Thanks for answering his question, he also had this other one…
@goenjoy Thx for the quick answer. Many SBC don’t have a GMS certificate and therefore don’t work with the Google core apps. I’ll get the system tomorrow and will try it out.
@goenjoy We where able to install “Android Device Policy” but unfortunately we got the error message
“Can’t set up device / This device doesn’t allow encyption, which is needed for setup. For help, contact the admin.”
After setting a PIN, we than entered Settings / Security & location / Advanced / Encyption & Credentials / Encrypt Tablet
This brings up the message that the device is not connected via a Power Charger (even so it is). We overcome this issue with shell command dumpsys battery set usb 1 with the App
Remote ADB Shell. This will mock this device as if it were connected to a USB charger. But unfortunately after trying to encypt the device it will restart but does not encrypt.
You can verify it on Android 10.0.
I verified it on Android 10.0 firmware, but after this interface appeared, I couldn’t continue 
The error message comes after the QR code scanning. Is the encryption working on Android 10?
Android10.0 SDK already supports file base encryption function.
