Pandora's battery went wrong

So, my psp got semi-bricked, It turns on, I can go into the recovery menu, but not the XMB. I tried to create a pandora's battery by removing 5th pin (aka the bottom right) on the chip with ICO4 next to it. Now the battery doesnt do anything it wont turn the PSP on at all. is it mybe something I missed or do you think something came loose? or did it just break. Its an old battery so it is pandora capable.

on recovery
try the option that says format flash1, I fixed a psp that wouldn't go into the xmb after using pandora by doing that.

Also if you hard modded a battery, you wont be able to use it as a normal battery

check the wikipedia link on my sig for more info
