Ok.. i've been working on trying to get my bricked gp2x back working for weeks. i've tried to use the gp2xrecovery tool, and the ocd commander method with the hacked uboot to no avail. I'm using windowsxp with my parallel port in ECP mode(i've also tried the other modes: bidirectional, dpp, normal). i'm using a parallel port with all 2 male ends that connect all of the pins together.
on power-up my gp2x starts out with a white screen that slowly fades to colored lines. I know uboot is dead. I think it died from leaving it on when the batteries were dying. it was working perfectly the last time i used it, then when i tried to use it next, i found that the power switch was on, the batteries were dead, and i was getting the colored line problem. I have the old gp2x 200mhz dual processor.
if i run hjtag it'll tell me that i'm using an arm920t so i know jtag can find my gp2x. when I run gp2x recovery i get the following:

some one in #gp2xdev suggested i link pins 15 and 8 on my parallel cable, which i did, and i still get the same output. everything i've tried gives me the same output.
I've tried using ocd commander, but i can't get it to connect. i've spent a long time trying to get the synching right.
i've done some research and i found that a regular parallel cable works fine. so I just need to know exactly what i need to do to get my gp2x running again so i can code.
