Baseband - DH12, Build = DI01 ?

[rapideyemovement]

I'm a n00b.

I'm rooted, successfully flashed CWM, and ready to install the Darkside Mod (DI01).

BUT

I've read that you need to make sure you system is DI01. Well my baseband still says DH12 but my Build is DI01. I tried doing the OTA update when it rolled out before I was rooted and I got errors all the time. So I tried applying a manual DI01 update from:

SCH-I500.DI01 Update - xda-developers

Mid way through I got an error.

Any idears?
