If i screw up on the bridges, is it fairly ez to undo using conductive pens?
It's very easy to clean up the traces from Conductive Ink Pens. They are really just real silver paint dispensers so cleaning them up with solvents that do not harm your chip.
what solution can i use to remove the ink just in case *&^% happens?
I have found acetone/finger nail polish remover(the old awful smelling type) works really well & has no adverse affect on the chip.
One thing that a few people seem to neglect when unlocking their chip is to properly fill in the pits with a suitable substance. Crayons/Wax jobs seem a bit on the adventurous side to me since heat can melt it. I suggest super glue as the simplest & most affordable solution to this. Now there are a lot of people that don't want to use this claiming that if they have to redo it cleaning off the glue is a pain in the @$$. Why does anybody have to clean up the glue????? All you need to redo is the paint. Below are other ways on how to fill in the pits;
- Tamiya 2 Part Putty. 2 sticks of clay like substance mix/twist together then rub into the pits/slits of your XPs. Wait a few minutes to harden then bridge L1 dots with conductive ink penn. Clean & easy
Squirt it on wait a few minutes then bridge L1 dots. Simple & fast. Great for soldering/volt mod jobs too.

I also tried some typewritter correction fluid(the white stuff) & have been succesful with it. The paint sticks to it really well & is very easy to apply with a pin.
