Less than a day after I got my gp2x, I bricked it when I tried to install the firmware upgrade. Now don't tell me to see http://www.distant-earth.com/gp2x/20...ked-gp2xs.html
Been there, done that several times with no luck. In order to be able to unbrick a gp2x that way, U-BOOT must still be intact and it needs to boot at least to the black logo screen. Unfortantely that's not the case with mine. It boots to a white screen that slowly fills with random colored lines.
I was using fully charged 2500mAh NIMH batteries (I didn't have an AC adapter) when I attempted the firmware upgrade. It sat at the 'upgrading firmware screen' for more than 15 minutes & then the screen went black. I left it that way about 10 minutes before I reset it and it's been dead ever since. I now have an AC adapter, and that doesn't help.
I'm in the US and our distributor is unable to replace it & GPH hasn't told him how to repair it. I want my gp2x working ASAP!
