Okay, so far I've used the tiff exploit twice. I used it to downgrade my friend's psp and I used it to play some homebrew on my 2.71. Every time i wanted to launch the program from the exploit, I would have to try multiple times due to the tiff's instability. Does that mean that when the next eloader comes around, you're going to have to try like ten times to get it up from the xmb photo menu?
