Help with possible 'bricked' Viper mod chip for GameCube

[urbangangsta101]

Hello,
Not really sure where to ask for help with this as its quite old stuff.....

Anyway, I have owned a Nintendo GameCube with a Viper GC Extreme Mod Chip for the last 3 years, it was professionally installed by a medical electronics engineer, so the soldering is perfect...
It has always worked flawlessly until tonight when I stupidly decided to upgrade the BIOS (Cobra 1.5 to Cobra 2.1) using the USB flasher hooked up to my Windows 7 PC.

First, I set the dip switches on the USB board (programming mode), connected the ribbon cable and sat it in the Broadband Adaptor slot, then
I hooked up the USB cable to the PC, installed the Windows 7 driver and opened the flasher program (Latest version included with the BIOS update) and the Viper was detected and connected fine.
As I stared the flashing process, the connection to the viper dropped out, causing a half baked BIOS to be flashed.

Now when I start my GameCube, I only see the official BIOS and not the Cobra one! I tried to reflash but I get an error now "USB flasher detected but cannot communicate with the Viper chip" also tested older flasher apps with older BIOS files - same problem

I stripped it down and checked the connections, all are still soldered well and the blue light on the main Viper board lights up when powered on, so it can't be that, and like I said, it was working fine before this....


Anyone experienced in this and know how to restore the BIOS? There has to be a way?
