I have an update on the project!!
Today I finally had the chance to completely remove the mobo from the Xbox and I just found out that it had a modchip installed in it. It is not the regular chip what I would expect because I was not able to see it from the top of the mobo. It was soldered on the bottom.
Strange looking thing as well because it has got like 30 wires or so. That must have been the reason I didnt suspect it had been chipped. Probably the reason why it reseted itself on every opening. Maybe the softmod and the chip confused something and not work properly together.
Now the softmod has been fully removed, it loads up the MS dash. The strange thing about it is it loads backups, slayers, HexEn just about anything really BUT I am unable to change dashboard on it!!!
Is it possible to change the dashboard on it somehow?
Thanks! Best regards!
