Px4 firmware downgrade

hello everyone, is there any option to downgrade PX4 firmware in windows ?
We are currently stuck with logging and we want to try to try downgrading software but i did not find anywhere on the forums, net how to do so.
Can anybody help ?

Good day, you can downgrade your firmware… you must download first the firmware corresponding to your fc…

After you downloaded it… just go on your qgroundcontrol… firmware… px4 flight stack and scroll dow to install custom firmware… just look where you have downloaded the file… select it… press ok… in the status bar will show you the flash of the firmware
