I have the OS MIO 4K with the SatDreamGr image (TNAP). I'd like to try some other images such as OpenVIX and maybe PurE2. What would be the steps for installing those other images while preserving the existing SatDreamGr? I have found some tutorials but none were a perfect match - either for another receiver or for other images. Also, would anything other than the hardware be shared? Any files? Or would they have their own independent file systems, their own satellite lists, channel lists etc? (my guess is that they are totally separate) Any potential pitfalls i should be aware of? I understand that some images are built for other regions and that I should probably update the Satellite.xml file once installed. Anything else? thanks in advance!
