yes the last updated for the moment is version k0901 by OTA at some and via USB by some others available at Hisense France!Just found out there is newer 901 firmware i might download later and try out.
It seems this TCON board fix doesn't work either.
for the TCON module the Hisense USA support says this time it's the right part.
wait & see.
FW k0901 for the 65 ":
