Ah yes, I missed the 3B+ requirement.
I was notified of the LineageOS 14.1 7.1.2 August 2018 update, and I started to convert it, but it got postponed due to Sourceforge's over eager false-positive checkers that I had to deal with and updates to PINN which took priority. I will get back onto it again soon.
Is 7.1.2 still the latest 14.1 version or is there any other updates in the pipeline?
I suppose I should also add LineageOS15 for the 3B+ models. Have there been any improvements in the graphics performance yet? But I guess if you have a 3B+, this is the only LineageOS version that will work anyway?
EDIT: Actually, I had posted the updated 14 version on Sourceforge in os_next, just not released it: https://github.com/procount/pinn/issues/194
, so it's available if anyone wants to try it.
