Note: you will need to setup [[tech:SSH]] to follow the instructions below.

The splash screens the reMarkable uses are stored as PNG files in ''/usr/share/remarkable''

These files can be copied off the reMarkable with scp over [[tech:ssh|ssh]] and then edited in a normal image editor that understands PNGs and copied back. Note that transparency, if present, is taken into account by the tablet (meaning that the former content remains visible where the PNG is transparent; this is used e.g. by sleeping.png in the 'light sleep' mode).

The filenames are reasonably self-explanatory, but it is worth noting that a second copy of ''splash.bmp'' is stored in ''/var/lib/uboot/'' (where a FAT partition for booting is mounted): you have to copy it over there if you want it to be shown when you power up the reMarkable. It also expects a specific version of bitmap format, specifically version 4, so you need the ''file'' utility to yield ''PC bitmap, Windows 95/NT4 and newer format'' on whatever you replace it with. One way to achieve this is to edit your image using ''GIMP'' and enable greyscale mode before exporting to ''.bmp'', which will then set it to version 4 automatically, instead of version 5 if you had maintained colour, which cannot be displayed by the bootloader. This image should also be rotated 90 degrees clockwise. 

Also worth noting is that the reMarkable displays a progress sequence of dots in the middle while showing starting.png, so it might be worth adding your contact details (or other changes) where they won't be obscured by this graphic.
