Thats badass... I had no idea, but I was thinking that may be the case as well as I see my SD card is getting full with backups located somewhere I cannot locate. I would prefer to start fresh each time. I really like Watermark, and this should help a ton. The side effect of my ignorance has had a tremendous side benefit because I thought it was my previous ROM, so I gave this a try, and like I said, holy crap! its fast!!
Thank you for the info , gona perform your steps each time from now on
NP!
This is definitely the best way to start fresh!
I have noticed that every once in a while, a ROM I am testing doesn't play nicely unless you flash it over another ROM (it's rare...but it happens). In that case, I perform all the same steps but then I flash a stock Motorola build (FRG22 for example). THEN before I reboot, I flash the new build over top of it. Like I said, it's rare and probably is a sign that something isn't quite right with the ROM or how it was compiled.
You can clear the download cache in ROM Manager (it will erase a copy of all the items you have downloaded).
Note: If you flash all your ROMs with the method I described, you will find that downloading ROMs from ROM manager is a pain in the a$$! For example, if you download CM 6.0.0 RC2 right now. you will have 3 files that you need to flash. You need to hunt through file folders to find the ROM when you "choose zip file to install from sdcard".
The root directory you need is: clockworkmod>download
(and then after that, there are bunches of file folders to sort through to find what you just downloaded.) You need to find the ROM itself, the gapps (google apps), and whatever launcher you selected to use...and all 3 files are stored in different folders.
As for the nandroid backups you have made, they are located here:
clockworkmod>backup (or go into ROM Manager and go to "Manage Backups").
No one ever said doing it right was easy
Sorry for the thread hijack...
