Well.... i go to hard mod my psp slim batt. i use a guitar pick to open the case and almost sever one of the foil ribbons that connects the circut board to the cell. It still worked. (left ribbon btw) now I went to cut the trace line http://www.psptoday.com/wp-content/uplo ... 498ty9.png I didnt cut the wrong trace i'm sure, it's just while i was cutting it I totally severd the ribbon because the knife slipped (didnt cut anything) and my hand holding the batt went the opposite way which caused the ribbon to sever. Can I simply solder this ribbon back on? Thanks for the help.
