Reinstalling old firmware?

I currently have 1.2.59 installed in my devices. How do I go back to 1.2.52? It would be awesome if the app would let you go backwards. We get the update option anytime we download new firmware. I am using a plugin for ATAK, and I need the older firmware to make it work.
Thankyou.

You can download the firmware directly from GitHub:

… or if you’re in Meshtastic Flasher, click on “Get Versions” and then click on the drop down link on the version selector on the left.
