That is the HTC stock recovery, doesn't look like the standard Android one.
Apparently there is a button combo to use to access the factory reset option etc.
Ha! lol thats MESSED UP! You're quite right Brad - you hold down (then release) vol up + power and bam! it jumps into recovery. Crazy!
I assume it is to prevent unnecessary or accidental access to recovery. I do recall it causing me a couple of WTF moments while I wondered if I had managed to brick it.
