Have to downgrade from 4.4.0 to fix issue. Is this only the firmware, or also the bootloader?
After a successful upgrade to 4.4.0 I got an issue with the sensor of the print fan. According to Prusa the way forward is to downgrade. I did find the procedure for downgrading firmware (USB stick, reset button, press twice the knob). But should my USB stick include an old bootloader as well?
Or will I run with the new bootloader, and the old firmware after the downgrade?
Thanks for the help.

No you don't need an old bootloader,
the 4.3.4 firmware also works with the new bootloader from the 4.4.0 version.
