If you switch the Desire HD to a ROM without HTC Sense (such as CyanogenMod 7)you'll find your battery life reduced even further. There is a battery drain issue with all custom, non-Sense ROMs for the DHD, due to a bug in the open-source code controlling the aic3254 chip used for processing sound (the closed-source HTC driver doesn't have the issue). Once the chip comes on it doesn't switch off, consuming power at a steady rate.

A few months ago I made the switch from the iPhone to Android - a HTC Desire HD (DHD), to be precise. I'm still formulating a post about my experience of switching (and Android in general), but today I want to document the process I had to go through to "root" my phone. Rooting your device seems to be a right of passage for Android owners and being the geek I am I didn't want to miss out.
HTC recently released an OTA update for the Desire HD (v1.72) which locked down the phone to prevent "rooting" (jailbreaking by another name, as far as I can tell). I find it amusing that the "open" Android platform suffers from some of the same vendor lock-downs as Apple and the iPhone, but that's another post for another day. What I didn't find amusing was that this update hit my phone the morning I decided I wanted to root my handset.
Thankfully there is a large community of enthusiasts who dedicate their spare time to working around issues such as this. Within a week or so there was a workaround. What follows are the collated instructions I used to downgrade my DHD to a rootable firmware, apply the root, install a recovery image, and install a custom ROM. These instructions are pulled from a number of different forum threads and blog posts across the internet.
