First I would like to say I think the guide is great. Though I don't have a lot of use for it, but I have some suggestions to make:
1. List some ADB commands and what they do, specifically how to use them, and what you would use them for. This forum has taught me so much about my phone and linux, but sometimes it was a slow learning process. Working the ADB push/pull feature was confusing when I first started using it.
2. Nandroid Back-ups. I still don't think I am using it correctly. I know there is a guide, but it still seems confusing. Maybe dumb it down a little.
3. Maybe more information on fastboot. I'm not sure exactly what it is or does, seems like just another version of recovery terminal, which from everything I have learned so far, if you can't get to your recovery terminal, you probably won't be able to get to your fastboot either.
