I rooted my last Evo w/ this, no problems. Sprint gave me a new one 2 days ago - 3.29 otb and hboot 0.97 - and I can't install HBOOT drivers. Install begins, then I get "The file 'WinUSBCoInstaller.dll' on Android WinUSB installation disk is needed". Please help.
edit: found file in i386 folder and loaded, worked. didn't have to do that last time, wtf? also, didn't install ROM Mngr, did last time. Wouldn't let me flash Amon RA 1.8.0. Installed ROM Mngr, said I had Amon RA even though I had Clockwork, selected Flash Clockwork Mod Recovery, screen blinked, said I had Clockwork and let me flash Amon RA.
