Nothing worked for me except:

sudo wget http://www.killernetworking.com/support/K1535_Debian/board.bin -O /lib/firmware/ath10k/QCA6174/hw3.0/board.bin
sudo wget https://github.com/kvalo/ath10k-firmware/raw/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00132-QCARMSWP-1 -O /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin
sudo rm /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin

Now I finally can use WiFi on Redmibook 13 Ryzen Edition. Contact me if you still have this issue.
