- download .84 firmware that TheLostSwede posted in this tread
- Download DIAG.EXE package from Dell (its package with this exe utility inside)
- Use DIAG.EXE to restore your backup file
- Use .84 firmware updater
I can see that they released 89 firmware, I am not having any fate in Aquantia after my 88 fiasco and not taking any chances. What particularly troublesome is that company provides firmware upgrade tool that doesn't provide any rollback/downgrade/restore ability in case of bad firmware release.
I have downloaded DIAG.EXE and restored my original bin file and after that updated to 84 firmware that you have sent me. My OWC is BACK!! Thanks a lot.
Thanks for the upload. Unfortunately, firmware updater doesn't allow to go back to 84 from 88. I have sent support email to Aquantia, hopefully they have solution for my bricked adapter.
