I ordered a new wii and will be following the guide to the T for my next board, in the mean time I'd like to try resurrecting this board if possible.
I did notice on the bottom side of the board I had cut rather close to the outer trace (red) coming of the AV chip so I scratch soldered a magnetic wire from one side to the corresponding via (orange points are where each side of the wire was soldered to)
The board also seems to get a little warm but not super hot, did I fry the board?
-Did you check the wii with custom regs and this setup before you trimmed it?
-Did you check continuity of all the lines amongst eachother and ground to make sure there weren't any shorts?
-Have you tried booting into Priiloader? This can be done by connecting a wire by connecting the Reset line to ground while the wii boots. This can give insight on where the issue is coming from
Checked the regs and wired them up after removing the on board regulators before trimming, just tried the reset button but the screen is black still.
For starters, you cut too close to an internal trace and removed 3.3v going to the U10 relocation (I don't know what else you may have cut off).
That trace is still there though and the corresponding pin is receiving the 3.3v according to my multimeter ?
the fact that you've wired up an SD card slot and not a USB tells me you aren't even properly acquainted with PortablizeMii. You were not ready to trim this board.
The first thing you should do is figure out all the places each voltage should be, and check those. Once you've verified that(you can post a list here) we can look into the additional intricacies that it might be.
I have had the USB wired up, however I have the 5v coming straight off the regulator to the USB pin and not to the board first I'm not sure if this matters or not? .. I know PortablizeMii is meant for USB and I know you can use SD as well that's why I have both. Well plan to have both at least as I only have the wires for the SD connected to the board and not the actual slot yet.
Just double checked the capacitors that the custom regulators are soldered to as well as the via holes that have voltages on the compedium and it seems to be getting the right readings.
