How bad have I screwed up?

This is one of my first times soldering. The 5 points I really messed up and have brown gunk everywhere. The other 2 (green and blue) were much better as I got used to soldering. The points look really bad now for the 5 because I have resoldered them 10+ times and still have absolutely no luck reading my nand. My question is: is there any hope left for this motherboard, or have I toasted it? Also, can I clean up that crap?

The error I get in jrunner is:

Yes your green n blue wires look ok to me. The rest is a mess.
Start again and use some IPA with Q-tips to clean up the mess.
Resolder the wires so they look on par with your blue n green wires.

Do I scrub once I get some alcohol on there? Cuz I already tried that before and it was a b*tch getting that stuff out. Hardly anything came off

Try wiring to the same points on the back of the board to see if that will work and try not to hold the soldeing iron too long on each point

I know this is a totally stupid question, Did you make sure the Power was plugged in before trying to read your nand?

Also make sure to get up all those small peices of solder slag. Just unsolder those 5 wires and scrub really good with IPA. That flux can be a bitch but it will come up. Then trim wires down and restart. Yes the points go through to the other side of the board but you should be able to make a connection just fine on the topside. Take your time and don't use too much flux, it only takes a little if you go ahead and make the connection quickly then move on to the next one

UPDATE: I have completely cleaned that gunk up and re soldered the points, but still no luck. I think I did I pretty decent job, so I think it's either a problem with the jr programmer or I have messed up a contact on the board

Could be a bad spi in the southbridge. If that is the case then you will need a parallel programmer like the demon to read/write to the nand.
