I got a youtube app from another link on another topic cant remember which one and now my youtube is actually playing for the first time I'm on tengcai mod firmware dont kno if it was the apk or fw bbut its finally workinthe OP was not specifically related to the "you tube app" not functioning... it was about you tube video not playing, continually buffering but no video playing. This issue is present for me on the actual you tube website as well as the you tube app.
note: I tested link directly above and this doesn't fix the "continuous buffering without EVER playing video" issue.
so far have never been able to play you tube videos (app or web) with aurora 2, tried all available roms except 0721.
Ya i was surprised cuz i tried alot of diff youtube apks and none would work til the one i got now i think it might be the tengcai fw that did it have u tried that fw yet?thanks kennyb, would be great if you could remember more about this fix, seems like im the only one with this issue now!
