shortcut issue after upgrading

well i have a w580i. i put the asia fw an cust pack and main on there, and it worked great. the only issue i had was that it would not let me set the up arrow to a short, but the camera that is on there now. well i did the americas pack, and it did the same exact thing. any way i get my phone to allow me to use the up arrow as a shortcut?

i think the up button is specifically set as a shortcut to the camera

well theres no possible way to get around that? i mean look at all the other things we can do to the phones, it seems something like that would be simple for those who know what theyre doing
