You need the firmware from /QCA6174/hw2.1 for your card

The firmware in /QCA6174/hw3.0 is used by the [168c:003e] (rev 32)

I would remove the existing ath10k-firmware from your home folder

rm -rf ath10k-firmware

Then download the newer one

git clone https://github.com/kvalo/ath10k-firmware.git

Remove the existing firmware

sudo rm -r /lib/firmware/ath10k/QCA6174/hw2.1

Then copy from the new version

sudo cp -r ath10k-firmware/QCA6174/hw2.1 /lib/firmware/ath10k/QCA6174/

Then rename the firmware file, next command may span two lines

sudo cp /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin

Reboot and see if the firmware crashes

Since the backports will not use board-2.bin we will rename it to board.bin. board-2.bin was added in the last month, may span 2 lines

sudo mv /lib/firmware/ath10k/QCA6174/hw2.1/board.bin /lib/firmware/ath10k/QCA6174/hw2.1/board.bin.bak

sudo mv /lib/firmware/ath10k/QCA6174/hw2.1/board-2.bin /lib/firmware/ath10k/QCA6174/hw2.1/board.bin

Reboot
