Here is the the video. It was not made by me and I am not in any way taking credit for just passing it along as it was the only thing that made sense to me.
Word of advice, if you are Hard Modding the battery, start to open it from the bottom.
IF YOU SEE A SPARK AND SMELL BURNING...i guess your fine, cuz mine did that "i is lucky to be alive w/ CFW PSP,
!"
I lifted the pin with a safety pin and knive, be careful! I thought i broke it cuz the pin lifted and went to the left and came in contact with another (thought that might fry it somehow) but it was fine.
It smells bad
