I attempted to solder the write points on my V1.3 xbox. I messed up the two pins near the LPC pins (on the front of the motherboard). It now frags (flash red and green) on me.
Of course I can still put a mod-chip on it, but I would prefer to try to get the TSOP on the motherboard working . I have not yet attempted to flash it so I have a good feeling the problem lies within a broken connection (probably one of the lines used to enable flashing).
I thought about trying to use the TSOP itself as a 29-wire mod. I found a datasheet for the TSOP chip. What I have in mind is to measure continuity between the TSOP and the places where a 29-wire mod would be installed. If all these measurements are good, then there is determining where those traces run to beyond the insertion points for the 29-wire mod.
