Yeah i downloaded the rom manager and then clicked on Flash ClockworkMOd Recovery and it says Current Recovery ClockworkMod 5.0.2.0. It then comes up with My phone "Desire" i click that then it warns about having a stable connection which i do then i click OK and it runs through without error (Green Bar along the top) once its done it says Successfully Flashed, ClockworkMod Recovery.
I click OK and then click Reboot into Recovery and then it reboots and that Red triangle comes up again and stays there. I then have to take out the battery and reboot it to get it back to normal.
