I dunno why, but I tried rooting my EVO and just ran into all sorts of issues with the HBOOT crap. This was a while ago, and I’m still unclear on a lot of aspects. I just never got back into it.
Even without root, I’m very happy with my Android OS but not the EVO hardware. My first EVO (which I lost) was flawless. Perfect hardware without defect. My replacement is a POS.
