Successfully flashed, but console power cut off immediately after
I've downgraded a good amount of consoles now, but it seems I've come into a problem here.
I have a CECHH fat console with me, which I made two verified dumps of, and managed to successfully flash. However, while doing this flashing I forgot to reattach the usb board to the motherboard. I usually exit to the XMB via the controller, but since it wasn't connected to bluetooth or usb, I figured I could switch it off from the back (clearly wasn't thinking here).
The PS3 will only turn on now for a few seconds, beeping three times and proceeding to shut off (much like a bad flash). What do I do from here? I would need this done tonight and I don't have a soldering iron with me. I know I can solder sbe to tristate, but I figured I should ask first before making a move, so I know exactly what's wrong here.
Did I short something doing this? Or flashing the console with the ribbon not connected? Like I said, the dumps were verified with 0 errors, and the flash went on the full 8 or so minutes, with no sign of issues. The console was on for a good few minutes before I shut it off.
Would it be possible to join the two points with electrical tape and wire? As mentioned I don't have access to my soldering iron, so what do I do from here?
