Hello, I have the Clara HD on software version 4.21.15 since a long time ago, and when I first bought it, I've modified it in many ways (upgraded memory sdcard, software patches, landscape mode, night mode, modified fonts, koreader and so on), but now I don't remember exactly all I've done lol, so maybe it will be impossible to replicate if the update won't keep them.

Now I want to refresh it by updating it to the latest version (with patches available ofc) but I'm scared that, by updating it, I'll lose all those mods.

Is there a safe way to retain those modifications? I did a full backup, creating a full image of the sdcard. After I've updated the software version, can I roll back to my current state by just flashing the image I've just created? (literally downgrading to a backup that has an older version of the software). Also, is it worth updating to the newest version? Never used wifi, I use Calibre to manage my books

Thanks in advance.
