Hmm, strange. Maybe that error in your bootloader is to blame?
Get the 90.73 bootloader from the SBF page and flash that and see if it removes that error.
Just be aware that it could result in you needing to start from fresh with your phone (i.e. everything deleted). I haven't ever had to flash my bootloader so I don't know what to expect. The risk is yours.
I would recommend asking around, because I am at a loss.
