HELP Both of my psp 3000 (unhacked) are BRICKED!!

[Neex]

Me and my sister's PSP 2001 are bricked! We never hacked them and I'm a total noob at this but please help!
yesterday I didn't even know what a pandora's battery was but I've followed a tutorial and made one.
All I need is a magic memory stick and I've been trying to make one but I can't find a tutorial for one without having to have a working PSP or sony camera/phone/device.

....I'm NOT kidding you... there IS a human life depended on this....

I have
-working normal psp battery
-pardora mod of a psp battery
-4GB memory stick
-8GB memory stick
- 2 bricked PSP 2001

(edit: sorry psp 2001 not 3000)

You could use PSP Grader v8 or one of the Rain's Ultralite MMS makers, but you will need some way to read and write to the memory stick. Some card readers that work with memory sticks will work but again the only way to make one is to be able to read and write to it.
