I have problem. On my HTC HD2 was HSPL3 bootloader. I wanted to change it to official version, by using RUU Leo HTC WWE 1.66.405.2 Radio Signed 15.30.50.07U 2.06.51.07 Ship image on FAT32 2GB SD Card. When I was turned on bootloader it was starter downgrade, but then restarted with error.
Now when i start bootloader it shows this information:

When I try downgrad again HTC shows Loading.. on grey screen and stay freezed.
When I try to setup HSPL3 again From my PC it "say":
