I followed all the steps at this forum link
and received the following error.
sending 'zip' (295144 KB)... OKAY
writing 'zip'... INFOsignature checking...

1. I checked the md5sum and it says its correct (image attached)
2. But after performing all other instructions the change from gingerbread to froyo didn't happen (image attached)
I have performed this downgrade and rooting on other Desire HD's but those had 0.92 hboot. This device and another I am going to do this on has 0.85 hboot (image attached). Not sure what to do next, after searching I couldn't seem to find a solution to my problem
