Hi,, recently factory reset my 4.0.4 android box but now I cannot install apps from Amazon playstore or Aptoide. Only google playstore works. I have gone into settings -security and ticked box to instal from unknown sources but still the same. Amazon appstore gives me a error when downloading a paid or non paid app (installed on 2 other of my boxes and tablet easily) and aptoide says download failure. Been stuck for ages on this now. Even showbox comes up blank with no movies. Everything was working fine before the reset. Help!!!!
