I just purchased a brand new avov tv online+ it has the 1.0.8 firmware and everytime i go into settings/sys info/sys updates... it does nothing. It will factory reset if i proceed to press that button. I've tried copying & pasting a few different update.zip files from people who has the zip file to do it manually and when i go that route the box does reconize and asks if i want to upgrade the firmware,but when i do it always says " NOT A VALID INSTALLATION PACKAGE!" I'm having the issue of the credentials process not going thru in order to get my iptv service up and running. (iks66.tv) My mac address is registered,my service is up and running,but i cant get past the credentials part and was told that updating my firmware should fix my problem,but i cant update it. Any help is much appreciated.
