I have followed the guide up until the point where I am supposed to execute the .bat file. When I do the file runs for a while until it hits this error:
C:\Users\ghett\OneDrive\Desktop\New folder (2)\Sailfish_OS-Jolla-22.214.171.124-f5122-126.96.36.199>fastboot.exe -s QV710PSD1T boot fastboot.img
Sending ‘boot.img’ (170 KB) OKAY [ 7.404s]
Booting FAILED (remote: ‘unknown command’)
fastboot: error: Command failed
ERROR: Failed to execute ‘fastboot.exe -s QV710PSD1T boot fastboot.img’.
Please go to https://forum.sailfishos.org/ and ask for guidance.
To me it sounds like the device doesn’t understand the command but I am unsure as to what I can do about it.
