Default Android Forensics

I am a 2nd year Forensic Computing student (UK resident/university) and I've been looking into a final year project which involves some form of forensic analysis of a computing system. Ever since I bought my HTC One and I rooted it, I've become quite interest in android as a whole. As of late, my HTC became carrier blocked (I bought it on contract from an eBay seller and they blocked it and won't respond back) so in essence I have a glorified media player but still a powerful device.
I want to make my final year project (Which accounts for roughly 40% of the degree) a forensic analysis of a rooted android phone.
I'm posting here (In the midst of developers) because I wish to attain advice and knowledge and some form of help (I'm not asking for anyone to do it for me, neither am I attempting to cheat) so I can produce a great project and a impressive dissertation.

Thank You
