Android device cannot be rooted. Alternatives?

My Android device cannot be rooted, thanks to Nokia. Is it possible to run the udp2raw client on my amd64 laptop and somehow use it from my phone?

Or does anyone know an alternative solution for unrooted Android?

Solved it.

1. Consider both the laptop and the phone are on the same wifi (campus wifi that blocks wireguard). udp2raw is already running and is usable on my laptop:

udp2raw -c -l [::]:55820 -r [2001:db8::1]:4096 -k "my_password" --raw-mode faketcp -a

Assume 2001:db8::1 is the address to your udp2raw server instance.

The listen address is unspecified: [::]:55820. This is important, and don't use a weak password!

2. On the phone, in the Wireguard app, edit your connection and set the peer Endpoint to your laptop's local ipv4 or ipv6 address (ip addr or ifconfig) and the udp2raw port (i'm using 55820).

Ta-da! The university's kung fu is not strong.

System info

• My laptop is running Fedora Workstation 39, with enforcing SELinux and default firewall configuration. I did not have to change anything.
• The phone is running Android 12.

@wangyu- It would be nice to add this to the Android guide, right? It's an alternative for people who can't root their phones. It's probably too obvious for most, but I'm a little slow - it took a while to figure this out.

I have added a link from Andorid Guide pointing to here, since it might not be obvious enough for everyone.
