HDShadow Posted July 22, 2020 Author Report Share Posted July 22, 2020 (edited) This is getting annoying. Just had another go at the soldering. Discovered pin 9 had somehow stopped showing any voltage and had to redo that again; now good. With pin 2 which was already grounded I decided to use SS_Dave's alternative grounding pad suggestion and that is now good too. D0 OK. BT point bridged - OK, both showing continuity. All other pins with the voltages as shown except for:- Pin 1 - 0 volts: can not get any voltage reading at all from this pin, not even a flicker. Pin 5 - 0.17 volts: no matter how many times I reflow or completely redo the soldering this is all I get. To recap: Xbox v1.1 up to this point a fully working softmod. Aladdin XT Plus 2. When I fit the chip to the pin header with IDE + HDD attached and D0 MB screw in place to ensure grounding it frags. Two short on off sequences with the chip LED coming on, then stays on but red/green flashing Xbox LED. Chip must have been working at some point because it booted an AID disc and, apparently, installed a chipped dash. But on reboot Xbox started fragging and that is where I am now still. Any chance the pin voltages are different for a v1.1? I think with those two problem pins I'm going to have to remove them entirely and check what the actual LPC contact ring voltages show. I find it difficult to understand how I can successfully solder 8 out of 11 pins correctly first time but after three more sessions have only been able to get one of the three problem ones reporting the expect voltage (pin 9 3.3v). Why 0.17v on pin 5? Obviously there's some connection but why so much lower that than the expected 3.3v?
