I hate to beat a dead horse, but since I don't have a lot of posts on this site, I'd like to put a little extra info in here...
I use ADB extensively, I even run backups through ADB, I have looked into Fastboot, but have not found any useful info, other than "terminology descriptions" and a few things from people that said "I think you can..." before talking about fastboot. I've only had an HTC Evo, Samsung Moment, LG Spectrum, and just got my Razr HD yesterday. My wife has a D4 I'm only allowed to touch when it stops working, although I bought it for her and flashed the ICS leak on it before she even knew she was getting it (it is now running CM 10.1). I have never made a Rom, I know it is not that hard, but I also know that others have more time to "perfect" their vision than I do, so I normally use other's Roms, and then change the internals to suit my needs once I decide if I like it. I have no qualms about manually changing build.prop info before flashing, modifying an updater-script, changing system files, swapping bits from other Roms and so on. I also ALWAYS open up any script I get from any of these sites and at least scan through it, sometimes making small changes to suit my needs, before I use them. As I prefer to do my Android tasks from linux, I frequently have to transfer .bat files to linux before I run them anyway. I'm not a complete idiot, just a bit clueless at times, freak out easily, am paranoid, lazy, socially inept, talk and type too much, and have frequent memory lapses even though I am not over forty and have only gotten high once (almost 2 decades ago) and a half dozen or so contact buzzes.
I have tried teaching myself to code my own Android apps, and spent a few months learning java, but I know enough about myself to say that I could never make my own Android app that looked good enough for other people to use, no matter how functional (I've never learned graphics in programming, I started in basic with ASCII text, then went to Cobol in college and that was about it).
I read every single post (as long as the thread was less than 10 pages
otherwise I just read the last 3 pages, set to either 25 or 50 per page) on three forum sites that were posted since mid Feb about the Razr HD, BEFORE I even had one (I started 36 hours before, and finished while it was sitting on my doorstep, although I did not know it was there... for the first time ever Fedex did not ring the bell or knock, and my daughter was awake anyway... I asked them to knock only in case she was sleeping)
I would love for someone somewhere to put up a nice tutorial on how to use Fastboot.exe for Droids and I'll read it end to end and start to use it when necessary.
(please understand I am not attempting to lash out, nor did I really take offense to what you typed, whether or not it was directed at me, I just wanted to explain, I have attempted many times over the last 3.5 years of android use to learn all that I could and to be if not an expert user, then at least partially informed and aware)

update before I even post...
I just discovered (with the help of google) that fastboot is an Android SDK thing, I thought this whole time it was just for Moto Devices, as various droid forums are the only places I've ever seen it mentioned.
command listing here for anyone interester:

and googling android.com for info only returns how to build fastboot from source
google: fastboot inurl:android.com
the one place I'd think to find info on it... which I might be able to if I went there and dug around the information there a bit deeper.
