You can really screw this board up if you do not have experience soldering. The solder on the right side of the RP12 hole is difficult to remove. I needed to turn the soldering iron up to the 720 Deg position. Also use a good solder wick along with solder flux to remove all of the old solder. Remember to cool the pads with Alcohol between steps. You risk lifting the runs then you have problems. The component in RP11 is a jumper (short) it may be some sort of fuse so try not to damage it and re-use it in the RP12 position.
