You can't just go about and use FW API2 firmware as FW API1 one. No
wonder device crashed.

Also you can't just place any file instead of otp.bin.

Moreover you're using an arcane version of ath10k. It's wasteful if
you're going to report problems that were already fixed. Please
upgrade the kernel or use backports:
