So i messed up. i soldered perfectly the dat0 line and i turned it over to do the chk and dropped the board. caught it by the wire and it ripped the copper pad off dat0. everything is fine with it. the board still works fine. but i cant solder that wire back. ive tried and theres no pad left to solder from. im wondering what my options are in that case? I like to think im decent at soldering. But im no expert. All that i know is that the pad is black. I tried scrapping it a little bit and using flux. but i messed with it for an hour last night and the solder wont stick. Any tips would be welcomed
