Frist of all apologies about my bad english, i write from Spain, and i think that the same happen, firmware 4.0.2 MAME don´t work and i try downgrade to 4.0.0 with brick result, black screen, i have cardle and i try recover with GP2XRECOVERY but without result, reflash was OK but the GP2X don't start, still black screen.
Someone has idea that i can try?
Thx.
Well, gp2xrecovery didn't work, I guess - since you can even recover a gp2x which has absolutely nothing on the NAND with it (I flashed quite a few gp2x F200 already).
Okay, make sure you:
a) Have an empty SD Card supported by the old F100 bootloader (i.e. no SDHC, etc.). I use an old 512MB SanDisk for this purpose.
B) Have extracted the full F200 4.0.0 firmware on this.
c) Then switch on the gp2x, start gp2xrecovery. Either wait until the serial output says it's finished or (if you don't have serial output) wait for about a minute after gp2xrecovery has finished uploading.
d) Remove the gp2x from the cradle, press and hold HOME and SELECT and switch it on until "Upgrading Firmware" appears
Well, bad news to report it seems. I received my parallel cable and attempted to recover my GP2X. I am having similar results as Kiname did. It appears to flash successfully, but when I get to the step of holding SELECT + HOME and turning it back on, it does nothing... black screen, blue light. *shrug*
I was worried about the problem being the SD Card, but I dont think its even making it that far. I have yet to see any screen other than black. I have done the process a few times, allowing various time increments from 20 seconds to 2 minutes between steps. Here is the DOS screen...
