Hi superfly can ou please repost v083, I can't download from there as it says to wait till februarywhat was your native FW ?
I tried to update to V191 which is on android 9, and update was failure. There is something wrong with the FW
here you can find v0.83Visit this link to download: V8-R51MT02-LF1V083.zipfiles.fm
Android 11 is in beta now, we have to wait for official final update
Seem like my panel is different from yours - ST6451D02-3. That may be the reason why your tv have a black screen while my tv is okay. Hope those who have ST6451D02-H could find a solution to it.
