Bricked USB4 power delivery on X870E AORUS ELITE WIFI7 after wrong firmware – controller now shows as IT8800, any recovery possible?

I’m posting this partly as a warning and partly hoping someone here has run into the same thing or knows a recovery path.

Board is Gigabyte X870E AORUS ELITE WIFI7.

The rear USB4 ports were already a bit flaky (iPhone not always detected, USB4 networking unstable on Linux and not working on Windows), so I made the mistake of running a USB4 / PD firmware updater meant for an ASUS board.

That was a bad idea.

After that, USB4 is completely dead. On Windows the controller now enumerates as: ACPI\ITE8800

From what I understand, that means the ITE USB-C / PD controller has fallen back to boot ROM mode, i.e. the main firmware is gone or corrupted. At this point:

  • USB4 ports don’t enumerate anything except fallback to usb 2 speeds
  • Thunderbolt / USB4 networking is gone
  • iPhone isn’t detected
  • Drivers, GCC, BIOS updates, Linux vs Windows, etc. make no difference

So this is clearly not a driver issue anymore.

I’ve looked everywhere and it seems like:

  • There is no public standalone firmware for ITE IT8853
  • Gigabyte doesn’t ship a USB4/PD recovery tool publicly
  • The only realistic fixes are vendor recovery, board-level programming, or RMA

Before I go too far down the rabbit hole:

Has anyone here actually recovered an ITE USB4 / PD controller once it shows up as IT8800?

Did Gigabyte ever provide a recovery utility, or is this basically game over without RMA?

Any insight from people who’ve dealt with USB4/PD firmware on Gigabyte boards would be appreciated. And yeah — lesson learned about never cross-flashing vendor firmware.

I did the same thing with my X870 GAMING WIFI6 (Rev. 1.x). I am not sure I have an ITE IT8853 though.

Thanks to this post I found out there IS A public standalone firmware for ITE IT8853. Do you still need it? It successfully flashed for me but I it is still showing as an ITE 8800. The ports no longer work with it. I had to erase PD again with 8857 so it would fail to get back to fallback to usb 2 speeds again.

sorry for the late reply after removing the heatsinks and closely checking I found out I have the IT8851FN128 chip and im still looking for a donor bin to restore my usb functionality

I have the same mobo.

I’d suggest you point LLM to fw updater you ran, maybe it’ll find some option to dump a rom.

I expect gigabyte to ship updates bundled inside their UEFI.

At least asrock and asus do, would be surprised if Ggigabyte didn’t
