Right... As far as I know the Netflix in the firmware must bypass some checks (like mac address) so the only thing to do is do a factory reset and DON'T update Netflix. Mine's working fine at 1080p.Oh I asked about netflix incompatibility after updating the app.
Otherwise I did see a youtube (MadeInChina) where he has a firmware for the T2Max with a mac address tool and a netflix.apk file that might work. He has a later video for using a third party APK for YouTube, Netflix and Spotify.
