I just saw that the upstream maintainer had noted the version numbering in the very commit that broke my WiFi.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/ath10k/QCA9377/hw1.0?id=56e5de3261877e5ca9df285e0751368c72b0861a What I've not tried is upstream's latest commit https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/ath10k/QCA9377/hw1.0?id=3e2e5d3c5bce21b4ef5bd89bad604e2be48c73b1 because it's not included in your latest 20190114-1. Would you like me to give it a shot? best Kevin
