Hallo, habe ein Problem mein BN2.01 Image mit dem Boot-Manager zu extrahieren und komme damit auch nicht an meine uCodes heran.
Beim aktuellen Bootmanager bekomme ich den Fehler: Dekomepressionsfehler - Superblock nicht gefunden
Beim Debug enablen per Kurzschluß ist etwas schief gegangen und die
Box meldete kein System. Mit mnflsh habe ich dann doch noch den Debug hingebracht und das org Image auslesen können. Aber anscheinend ist der wichtigste Teil davon kaputt gegangen.
Ist der Superblock vielleicht immer gleich aufgebaut (beim gleichen Boxtyp: Nokia, 2xI, 500, Sat). Falls ja, könnte mir jemand diesen Teil mailen (Auszug aus Hex-Editor o.ä. oden bin mit Angabe der Position, sollte eigentlich nicht der Anfang sein, da dort der Bootloader steht, wird vermutlich ab 128k losgehen)?
Dann könnte man vielleicht das Image wieder zusammenflicken.
Thx.

Versuch mal, das Image mit der Alternativ-Methode (dbox2.rar) auszulesen.
