Made using Ocean-Flame: https://ocean-flame-nu.vercel.app/
Firmwares starting from V3.7.0 (the 512mb and 8gb split's beginning) cannot be loaded using the original Flame-Ocean (Win98-themed) webapp.
However, Ocean-flame also supports moving all images from one version to another, this one was made from the v3.7.0 -> v3.8.0 using that "move theme" function.
Since I have the original 8gb model, I cannot test if this would work on an 512mb one as well, but as with every past release, you can see all source images in the `src` folder.
