htc hero v2.32.651.2 not rooting

[maygem82]

I have tried to root my htc hero and everything I have found is from the software before mine. It won't reboot and stays on the black htc screen, what's weird is that when you unplug the usb the little droid screen pops up like its trying to work and then as soon as you plug the usb back in the black htc screen comes back. Did sprint do something with the last update to prevent rooting? Help! My phone is super laggy and I desperately want to get this htcsense off my phone so I can thoroughly enjoy my hero.
thanks in advance
