Issue installing older operating systems on RM1

I was trying to go back to a previous version of the OS on my remarkable. It took me a while to get everything set-up with codexctl but I finally have it working. I was able to download the appropriate version of the image onto my computer but I keep on getting errors when I try to install.

Not sure what could be the source of the issue that I'm facing here, would appreciate any help to figure out how to rollback the OS on my remarkable.

```
MacBook-Pro:~ terraphorm$ codexctl download -hd rm1 3.14.1.9
