Zidoo has released differential packages via OTA for their model Z30 Pro.

New differential packages for the 8K series players to manually upgrade from v1.2.20 to v1.2.20_G are available.
Look what I’ve found on the Zidoo server. It has not be official released by Zidoo on their forum.
Totally awesome that Zidoo updated Home Theater even for RTD1295 and RTD1296 based players.
Update: DO NOT UPGRADE HT USING FILES FROM MCBLUNA’S WEBSITE
