Just found this post on another website:
"This is my first post (I think), but thought that I should share the method that I found work when it comes to getting root and S-OFF with the Telstra branded HTC Desire (stock ROM) with HBOOT 0.93, PVT4 and block size of 40000.
None of the various Unrevoked 3.21 and AmonRa 2.0.1/CWM methods seemed to work for me, so after four hours of trying different combinations of custom recoveries with different versions of Unrevoked, this is what I found to work:
(note, this guide is for OS X)
- download Unrevoked 3.3.2
- download AmonRa 2.0.1 (recovery-RA_2.0.1.img) (the Desire specific one didn't work for me)
- download AlphaRev 1.8"
Used a different Unrevoked program I see, your thoughts on this
