Small update:
The battery charging image feature implemented in the 1.4 version of the mods
seems to cause an issue when it is applied to a WM1Z. The issue is that the
internal storage will be seen as having only 128GB capacity instead of 256GB.
Because of that, I modified the installer for the mods, so if the player is a WM1Z,
the battery charging image feature will not be applied when installing one of the mods.
Also, if you already installed one of the 1.4 mods, you can revert the change using
a separate installer.
The installer allows you to install or revert this feature, so it can also be used by
stock 3.02 WM1A firmware users that want to have this feature.
I placed the installer in the GDrive folder, available on the link from the main post.

Edit: I already uploaded the new installer for the mods in the GDrive folder, that will not
install the battery charging image feature on a WM1Z.
