carbon XPL 3000 boxes on 1.6

[futbol tv]

go to aptoide market and do a search for buzztv
go to buzztv 2 and update

Hi, I know it's an old thread but I have two of these carbon XPL 3000 boxes on 1.6 that will not update. keeps giving me a "connect service fail" error when trying the update so I've done the factory resets, deleted data,cache, have a few GB storage left in it and I'm not seeing Buzztv in aptoide app.
also did an update to the Aptoide app but nothing. Has this been moved somewhere else?

I dont have any issues with speed but the menu side bar doesnt show me TV shows. so Im thinking an update to version 2.0 will fix this?
Thanks in advance for any info.
