It seems that's what I will have to do too. Except in my case the number of required steps is closer to 10 as my Jolla is one of the First Ones.

It seems completely borked underneath. HtheB may have been right after all, the aeroplane mode icon may be the least of my problems.. Any Store or Warehouse operation fails, no matter how many times I try pkcon refresh or to clear app registry in Utilities. Other than the two issues it seems to be working on the surface, but who knows what other issues lurk under the bonnet.

If only a reset wasn't such a hassle...
