Dear Raphael, in message [ref] you wrote:
BUT, there does not seem to be any JTAG connector or anything else (it's not a development board), and I don't have neither the skills nor the material to re-flash anything.
Are you sure there is no BDM connector somewhere (or 10 "unused" solder pads or so) ?
What I wonder is if it is possible to wire some JTAG connector
It depends. Ir may be possible, or may be not (some may be hidden under the CPU, and there is no way to contact themin such a case). And it depends on how much effort you put into this - and if the box is worth such an effort.
(I guess pins must exist, and if yes how may I find them), or if there may be an other way to load something like an other system. I have really no access to the underlying OS (no magic key combination, no magic reset, ...), so I guess it can only be done "hard".
Without a detailed hardware documentation (read: schematics) and/or sources for the existing software it will be definitely non-trivial to get anything else running on such a board.
