It's not in the thread but it's in the pic you just posted
After checking for update enter 2015 on your remote
This should update you to buzz 5 software
Your firmware is up to date
i am not sure they are going to be sending it out to all boxes Best to ask allaboutbuzz
when it is installed it wont be the same app as on the android 11s
It will be titled remote control in buzztv utilities
