I appreciate all the good advice - Even though my problems are of my own making, I learned a good deal these last couple days just dealing in the forums.
Unfortunately, at the time I couldn't delay. I needed to communicate posthaste, so while I was posting that message, a data wipe was in progress, and I proceeded to SBF. The only alternatives I saw were to, first, continue monkeying around with settings, and making failed call after failed call to my frustrated recipient, or second, to sit here and wait for a reply to show. An SBF was faster than both, so I just did it.
I'll go through the process again today. I swear . . . it seems like EVERY time I go through this process, even though I understand the steps involved well, and understand the concepts involved(a little less well), somehow something goes wrong each time. And when I figure it out, lo and behold, it's always my fault.
No time to mope though. Getting rooted and bootstrapped at the moment, ready for another try.
EDIT: SBF'd, rooted, strapped, flashed, flashed again, rebooted, and finally in business. You folks are awesome. Thanks again for your time.
