Ok so i got my slim xbox flashed a few months back by some dude who charges to do this. My question is, am i able to flash to the latest firmware without having to go back to him. Reason i ask is i don't have the backup of my original firmware or dvd key( not sure if i can recover the dvd key from my current LT 2.0+ firmware or if i need my original dummy.bin file ). Basically i don't wanna have to rely on going to somebody else everytime there is an update. Yes i'm new to this so any help would be greatly appreciated as i don't wanna stuff up my xbox or waste my time dissasembling it. I've seen numorous tutorial's but all of them basically show you how to flash an xbox that has never been flashed before, so i just wanna be extra sure before attempting anything.
