I got someone to make me a pandora battery and magic stick. Now I stick the memory stick in first then the battery and the SLIM doesn't automatically turn on and there wasn't any lights. The only way to turn it on was just pressing the on button. Did I do something wrong? or was it the person who made the pandora for me didn't make it properly?

I think the pandoras battery is fine.. except the original pandoras battery is for fat psp only... you will need to get despertar cementerio V3 and follow the readme and then you will be able to install 3.71 M33-2 on your slim... and if you cant make the despertar have your friend do it
