Root stuck on the rogers screen and recovery mode won't work!!

[KimCheeZZ]

hello! im new to android and tonight i tried to root my HTC magic. i went on the htc developers site and downloaded the radio and recovery image for 1.6 donut. then, i tried installing the radio using the way HTC suggest on their site, however, it doesnt work, it says that the files are not signed. so i tried to root it using theunlockr.com method (using flashrecovery.apk). i restarted, and installed the radio image. then i figure that i should restart. ever since then, the phone has been stuck on the Rogers screen and it wont even go to recovery mode!!!!!!!!

i cant really provide the info about my phone because i cant load it.
only things i know are:

1.5 cupcake
Build: 2.16.xxxxxx
my carrier is rogers
i live in canada

Any help is appreciated.
Also, if i bring it to Rogers, will they refuse the service since i tried to root my phone?? or will they just reflash my phone for me??

Thanks in Advance.
