I just received my GP2X on monday last week and it didn't take me a week to brick it. The 2.0 firmware came out and sure enough, I tried it with several things wrong, but of course I'm an idiot, so I didn't check before trying and bricked my unit. Here's what I did:
1)My SD card is an Integral 2gb card formatted to Fat16. Which worked for simple use, but according to the sd card guide, it cant be used for firmware upgrading.
2)NO psu, I used brand new freshly charged batteries I specifically bought at radio shack. The psu they had that fit, wasn't compatible with my unit, so I attempted it with the batteries alone.
3)The initial instructions on GP2X's web site said to start the unit with start & select pressed, as I later found out, this was wrong. First your supposed to just turn the power on, the unit will automatically detect the upgrade, then when the green screen is there, that's when you wait 15 seconds, then turn it off, then back on with start & select pressed. Well, too late, I waited 45 minutes with the chip screen on, the updating firmware screen, and then the batteries died. Now all I get is colored lines. From trying the unbricking guide, I think I destroyed u-boot.
So now, i've been contacting the company that sold it to me, and seeing if they are nice enough to assist, but if they cant, I need to learn more about this j-tag thingy. I have a cable that fits my gp2x perfectly, it goes from the serial port of the GP2X to USB, via a chip in the center by prolific. Can that be used as jtag, or is jtag something else altogether? I downloaded this linux software that runs on pc's in a floppy disc, that supposedly sees the jtag interface and forces the GP2X to re-right an older version of u-boot... but I have two problems,
1) I don't know how to read schematics.
2) I don't own a pc, I have a Mac G4.
So these are my questions to you guys, the GP2X gurus....
A) Is one of you willing to fix my unit at a fee?
B) If not, is there a servicing center I can send it to that will?
I appreciate any and all info regarding this and I thank you whole heartedly in advance.
