Those are some nice guides maderschramm, thanks.
I think I understand better now, although I am still a little bit confused.
Your guide doesn't talk about rooting, is that because flashing the (correct) sbf (with RSD) gives you root?
Once I am rooted can I then install ROM Manager to download ROMs and install them the the traditional way through recovery? or is that not an option with this device?
I'm going to hold off on rooting the DX, maybe I'm over thinking it and that's what is confusing me... I have had a G1, Droid, and EVO and have rooted them and installed custom ROMs without any issues (well I had a few issues with the Droid but that was just me being stupid)
I'm starting to think that people are using terms interchangeably like ROM and sbf and flash which is adding to my confusion. Many of the guides are great step by step instructions... but I guess what I need is a theoretical explanation of what is going on so that I feel safe following the guides.
