You can't unlock the phone from bootloader mode, and unlocking the device won't accomplish anything. However, if your device is unlocked, that could be the cause of your problem. The latest MR2 update from VZW does not work with the HSPL. When you're in bootloader mode, is there a line that says something similar to "1.0-Olinex" on it? If so, you're unlocked and will need to either re-lock the phone, flash a custom rom, or you can find Mr. X's fixed stock MR2 update that will allow you to use the stock software on an unlocked device.
