I use my Xperia 5IV since a while as my daily driver. Now I thought I give my Volla Quintus some updates and have a look, if main camera and flashlight is working in the meantime. Therefore I did a zypper ref and a zypper dup. Unfortunately ending in a device that booted just up to the Vollo logo. So I installed Volla OS again.
With the inital reflash, camera and flashlight doesn’t work in Volla OS as well. I had to update to latest Volla 15 to make it work. I have exported the Image of Volla OS 15, if that helps you @piggz, just let me know.
