Thanks, I looked at this FW now and it is exactly the same as the
"untested" in the ath10k-firmware repo
https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0/untested

So if that worked with ath10k several years ago (when?) I could try to
reconstruct an older version and try to bisect for a regression, though
I imagine it will be complicated to make these old versions work with
APIs that have changed in the meantime in Linux.

Best
