Description of problem: Most of the times the Xbox 360 boots within a reasonable amount of time (20 seconds or less). Sometimes though it takes longer and I will eventually get a red ring with errorcode: 0010. I tried all the dips on the R-JTAG board as on the board at the bottom. In the end the default settings worked best, meaning dip 7,8 and 4 on. R-JTAG is set to 1.2v. Bottom dips are on and in the middle. Bottom jumper is set to 470.

Was the console working before you started: Yes

Try setting power mode to either unbridged or 1v8.

MartinC thanks for your very quick reply.
Already tried unbridged, which didn't help. I'll try the 1v8. Do you think the problem is in tweaking the R-JTAG some more or could it be something else?

does it make a big difference if the ground is soldered to the board and not the av port just a thought , i had one that wouldnt boot just kept tweaking and in the end it did if that helps

I have a similar problem with the falcon. Where sometimes it does not boot. Sometimes 3 red light. Sometimes it freezes. Sometimes when you shut it down the lights stay on.

Where would you suggest to solder ground cable to the motherboard?
