Who wants a slice of 360?
With the new PCBs I can remove this part and it works !
100% on battery so Portable !

Then I analyzed and reconnected all the wires needed to cut out this other part, but after a lot of testing and research no boot.
The southbridge is cold (25°C instead of 50°C on), there is the middle green LED ON but not the LED circle animation of the start.

Currently I found the problem ! (I'm not sure why but I think it's very stupid).

Here is the full video :
The French subtitles are corrected so normally the auto translation should work well
(I don't do the English translation because youtube displays it badly and it becomes complicated to read and follow the video).

Good news the motherboard is not dead !

For booting the 360, a connected HDMI or video cable is needed, but that was not the problem here.
In fact I had just forgotten to color a part which is connected to the 3.3V and which powers the southbridge.
So of course I had forgotten to connect it.

After that I installed my PMS properly, and I was able to test that the new LDOs worked well :

The trimmed motherboard could very easily fit into a Wii
another size comparison for fun :

What's good is that I know I can still cut a few mm on the top, easily remove 5mm on the RAM side, and a little more on the other side.

Anyway, guys, here is the first trimmed Working Xbox 360 motherboard !!!

If you want more details or see me struggle, here is the full video :
TRADUCTION are not accurate YET, French subtitles aren't corrected yet, in about 6 hours it should be good
