Default Please Help! Tilt Stuck At Splash Screen

Hey Everyone, sort of inexperienced. I just got a Tilt, and wanted to change to the HTC rom. I ran the CID unlock thing, and all was fine. then ran the RUU, no problems, went to a 100%. After completion and restarting it shows the HTC 'smart mobility' screen for about 30seconds then goes off and restarts again. Now it keeps doing this until i take out the battery. I was able to perform a hard reset, no luck, currently tried everything i could find out there on how to get to the bootloader in the 30seconds or less i have but i have not being able to. I would be grateful if you guys can help!!!!!!!
