I previously jtagged my xbox 360 because I could not install cygnos 360 on the bottom of my motherboard cause the solder pads fell out. So i jtagged it, I was using a LPT cable to flash the nand but it couldnt detect it. I tried fixing the Could not detect flash controller problem but couldnt. So i removed the jtag and sent it in to have cygnos installed but the guy couldnt get it to turn on. I have recieved it and its true it doesnt turn on. Thats probably why it couldnt detect the flash controller. So the problem is most likely in the soldering. The powerbrick light just stays orange. What did i do wrong and how do i fix it?
