One thing which I think is missing is the information about the support level for each device. IIRC there are official, community and unofficial builds. It would be very helpful if this devices page would say which type of build is available for which device.
Hi @cedricoola there are 11 official Pie builds - but you are right details on which are the official / community builds that information is not showing up on our wiki. There are some updates coming to the wiki documentation and soon we will display this information as well.
For an upgrade also at present the process is the same - under request a build just raise your request and add an os-upgrade tag. Though this is not exactly necessary since we need to upgrade all models periodically. The one reason why this is not happening is we have not been able to upgrade the OS via OTA updates. I believe it is not possible even on Lineage and since we fork from there we carry the same issue forward Users will need to manually flash the upgrade. I personally think it should be ok as a one - time effort …while we work on getting this done OTA. This is why our Pie / Oreo upgrades are still delayed for a number of devices. Not all our users are comfortable with the manual flash method.
