I soldered the bottom points just fine, but the top points are a big messed up, I ended up with a both soldering points permanently removed from the board.
Are there any alternate TSOP write enable points I can do?
Any info would be extremely helpful..

Thanks for the help.

look at this pic:
http://www.xbox-scen...a_diagrams.html
forget the pandora chip but look at point " B "
This " B " seems to be same circuit as bottom solder point at R7D3 - it runs into a tiny etched hole - also has 2 other etched holes very close to it and when the board is turned over it looks like point B with 2 other hole near it.....
now looking at top R7D3 tsop again - the top tsop pad runs along a small track to R7D2 - and a track also goes from R7D2 2mm northwards......
If you poke a tiny tiny thin strand of wire carefully - ver carefully through this etch hole you should come out underneath at about 4mm North East of that point " B "
you should be looking at bridging that point B in the pandora diagram with anoth similar size solder pad 4mm N.East of it in the picture.......
NO - I AM NOT SAYING THIS IS 100% CORRECT - YOU HAVE TO CHECK, VERIFY AND IN THE END HOPE THIS IS THE SAME CIRCUITS AS THE R7D3 TSOP.....
you would need to use a small length of thin insulated wire kynar maybe, bit of quality solder with flux and not apply too much heat for too long which may have caused your top tsop point to go tits up.
FINALLY - I GOTTA SAY THIS AGAIN - I CAN'T SAY FOR SURE IF THESE POINTS ARE 101% CORRECT BUT MADE A QUICK OBSERVATION.....
THE RISK IS DOWN TO YOU AND YOU GOTTA CHECK THESE POINTS YOURSELF AND IF YOU THINK THEY MAY BE THE SAME CIRCUIT THEN IT IS STILL DOWN TO YOU IF YOU CHOOSE TO SOLDER THEM.
Up to now I haven't needed to look for alternatives to the tsop but just thought I would have a quick look myself just in case.....
Good luck - fingers crossed but the risk is yours - don't blame me if ya blow ya mobo up

| one other trick might be to follow the "split your tsop" tutorial - split the bios in half, and just flash the half that's write enabled |
Wait let me get this straight, I messed up my bottom, but my top is k, if I do the switch thing to flash my bios it will work? Right now Im stuck using my stupid Matrix which keeps missaligning.

IF thats Correct then we would want to know witch half the top and bottom unlocks.
But i might just be dumb

| Does anyone know the definitive answer? |
Um ... no. In every mod I've done I had no problem with the jumpers , and like I said in the beginning of my post, I've never heard of anyone burning them off before ( burying them in flux yes, burning them off, no)...
Why don't you *try*...? A switch shouldn't cost you more than $2, and the tsop switch points are easier than the write-enable points. You have nothing to loose but a stock motherboard...
As to switch position, try them both - if half of your bios is write protected, it won't flash...just move the switch and try again... btw, I never asked, but - if you were using anything other than a 15-watt iron on those write-enable points, shame on you!, and don't try it on the tsop-switching points, or you *will* burn those off...
