    My psp wont upgrade past 3.90. Ive tried both cfw and ofw- any version above 3.90 and the installation says its succesful, but it wont restart after installation.

    I have tried dc7 and 8, with the same results. If flash 3.90 or lower- it works fine. Higher and it bricks.

    This is a slim psp that has run cfw 5.0+ in the past.

    Any idea what the problem is? Thanks for any help at all!

    odd. i assume you've tried to install a higher cfw/ofw using hellcats recovery flasher?

    I have. I backed up my nand and tried using a known working nand. Same results. 3.90 works, 4.01 doesnt.

    I also tried formatting lflash and creating a new idstorage. Again, it seemed to make no difference. Its really strange to me that some versions would work and others not. I wonder if I have some hardware issue that is only affected by versions 4 and up.

    Ive done quite a bit of reading on it and Im not finding much that matches my situation. I appreciate your help.
