Reminds me of when I had to reverse-engineer the configuration and language format for an audiobook reader - I think it was the Milestone 312 [1]. We bought it for our granpa who is hard of seeing; but installing the polish language pack would stop the device from working correctly. In the end I had to compare a working english pack and the disfunctional one; the actual issue was something pretty simple - the names of the properties in their ini file were bad for some languages, and some checksums were wrong, or something like that. But it made for interesting black-box experience; there's of course no feedback about what went wrong in the device, nor any accessible logs :P https://bones.ch/milestone312.php https://bones.ch/milestone312.php
