6.2.3 firmware won’t calibrate heatbed

Yesterday I installed 6.2.3 firmware to mk4s and tried printing but filament would not stick to the bed. I noticed to bed was cold to the touch. I tried to do a calibration and test of heat bed but all I got was the rotating circle for preparing test keeps. Chatted with Prusa and agent believes it is bed thermistor. 
I thought it was to coincidental to the firmware update. I did a factory reset and went back to 6.2.2 and all is fine. Beware!

RE:

When the bed is heated the red LED should shine or flash. Dont you remember what temperature was on the display? But this is weird, because the printer does not start printing until the bed temperature does not reach the temperature set. 

Did you download the 6. 2.3 FW for the correct printer? I have 6.2.3 without any bed heating issues.

I use FW 6.2.3  on MK4 without any issues so far.
