Thread: magic stopped working

hi,
i had a go at updating my rooted google magic but gave it up as a bad job.
anyway after about a week of it working fine i downloaded from the marketplace lastnight an alarm clock but i came to my phone this morning & the phone is switched off.
it will start with the vodaphone screen then it goes to the htc screen & then thats it. every so often the HTC screen blinks then comes back on.
please help as i'm stuck with out it
thanks.
