Should be a simple fix. Just run nsmb ntsc, original or backup, with update partition, and run the disk update.
When your done, reinstall HBC to fix that issue, yours sounds old and the update must have killed it. HBC installation is described in step 1 of the 3.1-4.1 softmodguide linked below. Be sure to install bootmii as boot2.
Also other options to fix this issue are described here-
Semi-Brick, system settings locked, Opera error.
