Am I Screwed?

[ChipStewart]

Hi. I purchased a AirCard 779S that was a Boost modem with a Sprint SIM card. Boost would not unlock it, since it was new and hadn't been used on Boost for at least a year. I thought I'd try DC-Unlocker so I could use it on my T-Mobile Account. I purchased the 10 credits and followed the instructions. Unlocker said the 779S was unlocked, but when I put in the T-Mobile SIM card, it wasn't recognized, and I still received a "Activation Required" message. It wouldn't activate. I did a factory reset, took out the card, re-unlocked it, but got the same result. After trying a few times, I then got:
================================================== =================
DC - Unlocker 2 Client 1.00.1430

Try DC Unlocker Software version 14.28 or 14.29.

That's because you have selected com ports manually. After you do auto-detect as per guides then it will work unless you already damaged something.
