Problems with Firmware

[Darkmann]

Hi,

i have some .cso files. On 3.80 M-33 the files is running, no problems. If i install a greater firmware i only get a black screen after the PSP Logo.

Testet with 3.9, 3.9.3, 4.0.1

All menu settings are the same. Only the kernel are that one who is in the firmware.

Any hints for me ?

Greetings Darkmann

Greater firmware as in 3.90 official firmware or 3.90M33?

M33 Firmware

If you're still on 3.90M33, try applying the THIS patch

I have installed the FATSMOD patch. But the same problem....

Hm....
See if you have the UMD Mode set to sony np9660.

Format the stick (backup first) and try again

Try the different drivers, i have found the Sony Np9660 to be less reliable on 3.90 / 4.01 M33. I now use the M33 driver. When i was on 3.52,3.71 i always had it to the sony driver.
