BCD436HP/BCD536HP: Reverting to earlier version of firmware

Hi folks,
My 436 is currently at version 1.10.02 of the firmware. I would like to try the latest version of the firmware to see if it improves my P25 simulcast reception. However, if it happens to make things worse, I would like to revert back to my old version. I see a bin file in C:\ProgramData\Uniden\BCDx36HP_Sentinel\Updater which I think is the current firmware file. (correct?) Can I copy that file to another location, update to the new version, and if I wanted to revert back, bring my old copy back into the Updater folder to replace the newer version?
