Help needed for complete novice

Hi everyone...
Just bought a slim psp, running 3.80.
Bought a datel service battery and created a magic memory stick, but when i try to boot the psp nothing happens....i read a lot of the other posts on here that say the slim is a blind install, but even pressing x to try and do it blind doesnt work, the memory stick light or wireless light never even flash..
Am i doing something very stupid or have i managed to get a psp that cant have cfw???
Any help will be greatly appreciated before i decide to sell the psp and buy one already done..

Do i need to use a psp running cfw to create a magic memory stick??? if so then this is where im going wrong..

I think you need to re-do the magic memory stick

i have tried doing the magic memory stick on 3 different cards, 4gig, 2gig, and a 1gig, all with the same result...seems really weird, not sure what to do now...

Try using UPMS to create the memory stick
UPMSInstallerV4 for PSP
Its an all in one Pandora memory stick capable of installing all custom firmwares and retail firmwares from 3.71 to 3.90

You should not have to do a blind install anymore with the SLIM.
