GUIDE How to Flash Custom Firmware on Thunderbolt Card for macOS

[EliteMacx86]

I'm trying to figure out where to find the firm that can be flashed on the onboard AIC Dell JHL6340 (On Dell G7 7588) but i don't know which one will work for me. I mean maybe i can make something work just about modify the stock firm or i need to patch ACPI tbh. Can someone help me with this problem ?View attachment 7940

Start with the TB implementation first. If it does not work as intended, then try to flash the custom firmware.

Does anyone have the original firmware .bin file from a Gigabyte Alpine Ridge v1.0 AiC? I am gettin an error code 31 now, and think the firmware is corrupted. I want to make sure it's working properly in Windows before I flash it for MacOS. I did have it working on a hackintosh build, but since I updated the CPU, I haven't gotten it to boot again, so I have fallen back to Windows. I never changed the firmware on it, but I have an SPI flasher now. The firmware file that's on the Gigabyte site doesn't load. It says it's too small. It should be 1MB. Thank you.

Where are you specifically getting this error?

You can add extra padding or can try the GIGABYTE Utility to flash!
