So, just to make sure I got this right after reading all applicable posts:

1. Fastboot replaced SBF?
2. Fastboot wipes system sector and replaces all system files with "out of the box, like new" files?
3. A data reset post fastboot flash wipes data sector (and internal sd storage)?
4. The utility has all needed files?

Thanks in advance for confirmation / clarification / correction on the above questions.
