First : No i'm not a troll, he closed it due to the risk of brick that's why i just pushed a commit on GitHub where if people install a title that may brick their Wii U, it prints out an error
Second : I don't know, but do not try, i'll do every test i need to do before remaking a new release thread
Not enough testing, but i made some testing about creating .tik and one of my helpers just find how to do a .tik trick and install it correctly
Nah it's not any trick. Your youtube installation worked because you had it installed previously (either eshop or pre-installed).
