Hi all, I would like to restore my original bootloader on my Desire. I have two - one purely stock, and one that I rooted and S-OFF with unrevoked. The one with S-OFF (security flag off) needs some warranty work so I need to set S-ON. I have the RUU for US Cellular and can get anything I may need for the working phone. Please help! I am willing to try pretty much anything to get it going.
