Hello friends.

I hope you can help me with my problem here .

First of all thank you for your forum, I just found it but already helped me with another PSP I have .

My problem is with an older PSP:

I have a FAT PSP-1004 Date Code 6C. Here are the specs:
- System software 5.50 GEN-D (Full);
- Battery model PSP-110;

The probem is that I downloaded the sony's original "EBOOT" file to upgrade to 6.60 version and followed your tutorial and I get the error code DRNFFFFFFD7. I already tried connecting to WiFi and make an update, but it says the software is already in its current version.

Can you guru's help me ?

Thank you in advance,
