How To unlock and flash with Video Walk Through!

how do you put it back to original I have the HTC touch Pro i think that I might have messed up something cause my phone only does half of what I want it to do it doesn't ring I have to litteraly watch it so i can answer when some one is calling me the screen rotates with out even sliding the keyboard out and the screen even changes as if I slid it out the only mods I did were the notification message and change the clock to crystal, speed hack and unlocked it noting else has been done. if you have ran into this issue all help is appreciated but not required but I would like to know how to set it back to original and maybe start back over.
