i deleted something on my 8310 that i thought was a bb theme. turns out it was the os. or something that deleted the os. now my screen is all white with the small icons and 507. i tried just to reinstall the os but nothing happened. downloaded DM 4.3 nothing happened. deleted and reinstalled the os on my pc nothing happened. deleted the XML file nothing happened. i read the the os update sticky and it said if i open DM and plug it back in i should be promted to update it while on that screen. didnt work. i tried jl cmder and wiped it but its still the same screen with 507. and now im just lost. any help will be most appreciated.
