Made mistake on CDMA Workshop, HTC Android stuck on boot loop

[Lan05]

Hello, first time poster, and first time needing help that I can't seem to find anywhere. I'm posting under general since it may be a general problem for any HTC Android phone, mine is for the CDMA Sprint HTC Hero. I've searched hi and low and tried every type of method for restore including goldcard. Please note that this phone was in stock 1.5 and unrooted. My problem is when I went into CDMA Workshop, I made a small mistake under the NAM tab and accidentally disabled the PRL. Once it restarted it then kept going into an infinite loop, restarting as soon as it got to the main lock screen. I was wondering if there was any way to have it connect to CDMA Workshop without having to go to the main screen. Again I've tried a lot of methods. Thanks.
