Hi Max
I can’t really do a new IodéOS build for z3tc and z3tcw as they are 32-bit devices, and Iodé don’t make32-bit builds of their apps (Iodé App and Iodé Browser). Vincent did a ‘one-off’ build for the original builds in this thread. But I think there are no plans to do another, particularly as these devices are pretty much ‘end-of-life’. I think the best solution to keep using the tablet is the new build of LineageOS for microG. It has the necessary patches to work with Google’s latest changes to how their apps are signed, and I think that is the most up-to-date OS you’re going to get for this device.
Sorry!
Pete
