Here is an output of what I get when trying to follow the guide on TJC:

Code:

The computer can ping the Jolla C at 10.42.66.66, and I have run this from it and it returned no error:

Code:

sudo sysctl net.ipv4.ip_forward=1 
sudo iptables -t nat -A POSTROUTING -o wlp2s0 -j MASQUERADE

But somehow, something is still perventing it to share internet to the Jolla C, or the Jolla C to pick up.

[Edit] Finally reset to factory state, I love my original Jolla and I largely prefer it over my Jolla C for its form factor actually, but there is an Androdi application that requires 4.4.4 that I need to run and I can't on the Jolla due to its older version of Aliendalvik.
