Botched Relock, Phone Not Working

[DrSuSE]

Hey guys... hoping someone might have some insight for me.

I need to exchange my TP so I reflashed to the stock ROM... no problem.

However, trying to relock the device has been an issue.

It got to 50% and the device reset and now trying to relock it stalls at 0%. If I just boot the phone normally, it says SPL-0.37.0000 BUT it won't go past the bootloader, it says:

Upgrade ROM code error
Please try again

If I try via Windows utlities I get error 262 regardless of trying to unlock, relock, etc.

If I load the unlocker NBH unto an SD Card it says "Loading..." and stalls there indefinitely.

Any assistance would be appreciated.

Thanks!
