I have an Asus ProArt PZ13. It's currently running BIOS version v307. There's a Qualcomm Board Support Package update that includes an update to v311. Whenever I go to install that update, i'm prompted to reboot as expected, it reboots into the firmware updater but as soon as it gets to 6% it immediately jumps to "Update complete! system will restart" and when it does reboot, I'm still running the old BIOS and if I go into the Windows Device Manager I see an entry for the for `ProArt PZ13 UEFI BIOS`, in the "Firmware" tab there, it says this:

Firmware Version: 1C200307

Firmware is pending update on next system reboot.
Pending Firmware Version: 1E780311
Firmware failed to update during the last attempt.
Last Attempt Version: 1E780311
Last Attempt Date: 13/06/2026 13:18:22
Last Attempt Status: 0xC0000001
Firmware update was unsuccessful.

And it wants me to reboot again, which if I do, I have the exact same scenario and i'm still stuck on the old bios.

It's as if the firmware update is giving up silently at around 6%. Is there anything I can do to get around this?

Obviously I can't use EZFlash because that's not available for ARM devices (I've tried). I have the .311 file for the BIOS from the driver package, but it just seems the UEFI upgrader/installer is broken for it. And before you ask, yes the laptop is plugged into the power (the UEFI upgrader refuses to continue unless it's plugged in).
