Okay, so I have a Sprint Hero CDMA which is like half-rooted? It was not rooted, was running on the Sprint 2.1 update. I dropped it back down to .5, got through the rooting aspect, have SuperUser in my app tray, but now it won't let me boot into the recovery menu! Every time I try, it just pops up a black screen with a phone on it and a big red Caution symbol over it... Any ideas how to fix this so I can finish rooting my phone or even use the recovery menu options???
