I'm stuck in factory/service mode after try'ing to downgrade 3.55 to 3.41 using my ps3key.
I got it into factory/service mode and try'd to boot with my FAT32 usb in the most right port with the file 1 lv2diag.self and the modified 3.41 PUP but it just boots normally only still in factory service mode.
And at this point i can't even get out of factory service mode. Try'd to put the file 2 lv2diag.self on the root of my usb butt nothing happens.
Keeps booting in factory/service mode.
I'm desperate and need help.

The best answer is 1 that helps me downgrade my ps3 to 3.41 butt if no one seems to have the knowledge to help me at that point then at least help me get out of factory service mode.
