1. Originally my problem was that the youtube program wouldnt start. When I followed m@rco's instructions and changed the youtube file's name in the windows directory it worked. When I tried watching a movie in youtube it wouldnt play it though. So I tried playing other movies, in the media panel, the camera application and windows media player, and none of them worked, all of them give very loud static and a black screen.
2. I can't watch either, and yes I have the other youtube cab installed.
3. Yes I've installed the fix, but before I changed that one line m@rco told me to change manually. I doubt running the fix again would do any good but I can try.
4. I did install the other one first
PS. How to do a hard reset then? I tried starting the phone with the two buttons pressed but clearly it's not gone back to the factory settings, or atleast, I dont believe it did, as none of my data was erased. But at this point I think I'd rather start all over from scratch with a working X1 and just install the right cab's instead of old TF3D's
