How to revert to an earlier firmware version?

Before I upgrade to 5.3.4, I’d like to know how to roll back to my current version which is 5.2.1. How can I do that?

You should be able to find and download the 5.2.1 version of Aeros firmware here Aeros Firmware History scroll down the page just a little until you see 5.2.1 and download it Download the 5.2.1 update file here

Once downloaded, follow the directions for installing it from your SD card.

Thanks for the quick response, ,much appreciated!
