There's been a few posts recently about Zgemma support.
We are about to start supporting Zgemma new generation 4K receivers. The first models to be supported will be the H7 series, H7S and H7C. We are also testing the H9 series. H9 series at the moment needs a bit more work, so nothing guaranteed until we actually release images for these.
We will be relaxing the Forum rules on Zgemma receivers, but please note we won't be able to provide support for early generation models that OpenViX has never supported.
Zgemma models that OpenViX supports will be listed on the forum and on www.openvix.co.uk, if you're receiver is not listed it's probably not officially supported. There are images available elsewhere that where not provided by OpenViX.
