Chatroulette francese - Psp zes when updating

First off forgive me because I am past the frustration point I connected my sons psp to my ps3 and downloaded some games and demos for him, fairly painless procedure only to find that now I need to update his psp from 3.6 to 3.8...can this not be done via the ps store?I thought I could d/l it to the ps3 and transfer it to his psp?I clicked yes and it told me I the following statement:"The system configuration of this PSP (TM) system does not appear to be correct. How can I fix this, any help would be greatly appreciated, thanks a lot.

This could be the absolute reason why you can't install the firmware.

The files in your psp were modified....permanently, and there are only very few solutions to that.

This update is for customers who own PSP systems with model numbers PSP-1001, PSP-2001 or PSP-3001 sold in North America.

DO NOT update your PSP system through this Web site if you purchased your system outside North America.

I'll already tried updating it via Wi-Fi, same problem.
