Help with Lumines downgrade.

[actionfigure73]

Greetings all, I assume this is the place for me because I am a PSP noob, proud PSP owner of 4 weeks.
I've downloaded the Lumines downgrade and have the proper legit copy of Lumines (ULUS10002).
I've follwed the readme to the letter, but cannot get my PSP to load the X.YZ update.
I keep getting an error message asking me to verify that the UPDATE.PBP is a valid EBOOT.PBP .
My system info shows that I'm running 3.50 HEN.
I would appreciate any help.
Thanks.

There is a reason why they call them README.TXT or HOWTO.TXT

Besides, there´s always the option for googleing!!!
