wow, that's rough. stock rom and everything?? did you try changeing the system settings? force monocore (i don't know if your phone has dual core), and the interpreter option.
if you're using the bios, you should not have any hle pop-ups. that's something that I don't understand. you could try a different bios file... turn off the quick boot so you can see the bios screen. again, if you're using the bios, try disabling it (go to select bios, and just push the back button to get to the menu).
