that's why people with a flashed TSOP shouldn't mess with modified bioses. recovering is hell.
your best bet is to send it to someone who can install a 29 wire mod and reflash the tsop, or forget about the tsop and get a decent lpc modchip.
considering you managed to kill the A18/A19 points, I suggest you DON'T try soldering it yourself.
if I'm reading this right what you seem to be suggesting is that I don't have the ability to solder. Well, I am a very capable solderer, I modify PGMFI ECU's on a daily basis. What happened is that there is simply no solder left on the board on those points. Now I have access to a xenium chip, and have considered booting and pulling it. any further
