Thanks.
I've tried all of them, like literally, mostly focused on crashd and getmein. From what I found is that even if there will be a working root for my firmware and OTAID then there's now a problem with autostart of apps. So I gave up and just bought a passthrough grabber with hdmi in and out that I will plug to my roku stick and tv and the usb I will plug to my miniPC running proxmox. Hopefully that should work out.
