dijkhuizen057 Posted June 14, 2023 Report Share Posted June 14, 2023 Hi guys, i have an openxenium with latest OS and cerbios 2.3.0 mounted on a 1.6 xbox and it works fine. When i place the modchip into my 1.4 xbox it won't boot (it frags). D0 is connected to the correct point on the motherboard. I believe cerbios 2.3.0 is an all xbox version ?. Should i flash a 1.4 bios into it with the launch menu ?. I also have a duo x modchip and That one boots fine.(on the 1.4 board) I am puzzled ,can it be a poor connection on one off the lpc header pins ? Somebody can give me advice ? Thanks.

SS_Dave Posted June 14, 2023 Report Share Posted June 14, 2023 It should boot to the Open Xenium menu when you power on the Xbox using the eject button. Try grounding the D0 point on the main board instead of wiring to the mod-chip. It is sounding like a install issue and by uploading a good quality pic or 2 of the LPC install to a share site and add the link here will help us see if it's a soldering problem. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted June 15, 2023 Report Share Posted June 15, 2023 Remove the v1.6 solder bridge on the top of the OpenXenium PCB. It should not be connected for a v1.0-1.4 Xbox. 1 Quote Link to comment Share on other sites More sharing options...
Bowlsnapper Posted June 15, 2023 Report Share Posted June 15, 2023 God DAMN the compatibility differences between the 1.6 and everything else. It's such a pain in the ass sometimes. lol. Quote Link to comment Share on other sites More sharing options...

dijkhuizen057 Posted June 15, 2023 Author Report Share Posted June 15, 2023 Just now, dijkhuizen057 said: Yes i already did that. I found out that modchip is not the problem. I placed it into another 1.4 board i have lying around and it works fine.The modchip in the suspucious board powers on 3 times and then the green /red led flashes. So it is definitly a mainboard problem. I will check cpu capacitors and soldering at lpc. Will get back on this. Thanx for your responses.I appreciate it much.

dijkhuizen057 Posted June 15, 2023 Author Report Share Posted June 15, 2023 I removed the wire from BT to eject button.i soldered 3.3v pin header connection to Bt. I believe this is irrelevant to the problem. I resoldered all pins of lpc, et voila it is working !. Quote Link to comment Share on other sites More sharing options...

Congrats on getting it working buddy. Quote Link to comment Share on other sites More sharing options...
