Usando el dcon2 "opcion u de upload firmware y renombrando los firm a firmware.app" y el Tvboxedit "opcion de box software update", le he metido a mi mm24020 los dos firmwares de linux que me han parecido mas compatible con el (uclinux-mb86h2x-firmware-0.1.app , Digenius-DVB-S-uclinux-0.1.app y Digenius-DVB-S-uclinux-0.2a.app). Los tres han cargado, pero el Digenius 0.2 parece que no se ejecuta bien y da errores al final. El uclinux-mb... es muy curioso, y acepta los comandos que se le meten desde el terminal, unos poquitos. Estos firms se cargan solo en memoria, y tras apagar el aparato y volverlo a encender, se restaura el firmw normal de Medion y las listas de canales. Una curiosidad, mas que nada, ya que son solo pruebas en Linux para hacer un set top box linux operativo.
Este es el dump de la instalacion de uclinux..:
