3.1.4 firmware calibration problem
I upgraded my Mk2s to a Mk2.5 and installed the 3.1.4 firmware. The self test went OK, but when I tried the XYZ Calibration it failed with "Calibration Failed". I retried 3 times - all failures.
Without altering anything, I downgraded the firmware to 3.1.3 and tried the calibration again. It succeeded! The first layer test also went smoothly.
I did notice that when the 3.1.4 firmware was installed, during the calibration, the bed attachment point hit the front (when it was detecting the rear calibration points). Not sure if that was the reason, but it certainly didn't sound healthy.

Thanks - I don't want to break anything before I produce my first print, if my upgrade ever
gets delivered - my regard for Prusa is dropping every day that passes!

Re: 3.1.4 firmware calibration problem
For me 2.1.4 failed two times, but 2.2.0 works fine ( https://github.com/prusa3d/Prusa-Firmware/releases ).
