Pandora Battery won't turn on PSP

[Mupp3t]

Here is my problem.

I bought a pandoras battery from pandorasales.com. It got here in 3 days, memstick included. I take out the memory stick and battery, and make sure the pandora is charged. I put the MMs in the psp. So far so good. Then i put the battery in and hold L1. Nothing happens. I try again, and again, and again, but nothings working.

I will put info below.

you have an unhackable psp and there is nothing you can do with the pandora and mms to unbrick it.

Try looking on eBay for another mobo for your 3000. Such as this:Sony Slim PSP 3001 Part TA-090 Motherboard 100%WORKING | eBay

Are you getting any errors while making your MMS??...for example "failed to inject IPL"?
