Noob alert...although I have bothered to have a quick search of the forums. However, if my question is answered in another thread, please point me to it! I'm interested in rooting my Desire HD and applying a custom ROM to it. However, if I were then to return my device for repair, I wouldn't be able to do so, unless I could prove that legitimate software/radio, etc. were on there. So...if I install, say, LeeDroid 3.3.3, could I then return to the HTC Desire HD UK setup? If so, what's the best way of doing this? Can I simply back up my current setup, so as to have the option of reapplying it if required. Thanks in advance, Rich.
