Great work, @rinigus. Thank you!
Edit: running it on my XZ2 (as reported on the github repo) and everything works swimmingly, aside from the minor regression in jolla-messages related to MMS. I haven’t tried it yet, but apparently downgrading jolla-messages and jolla-messages-settings to their previous versions solves it. Thread here. I’ll try it later and report back.
Edit: UPDATE: Following the procedure in the thread I linked results in a PERFECTLY functional MMS experience on this Tama port. There’s a regression in the jolla-messages app in 4.3.0.12 which makes MMS fail for varied reasons, with minimal indication (or no indication at all) in journalctl and ofono logger. I’ve been banging my head against this for a while, and this works 100%.
