Hey, currently my PS3 3.41 is in service mode and i want to downgrade it to firmware 3.15 so i can have the OtherOS feature. I have followed all the procedures and the console is in service mode, i placed the 3.15 pup file in the PS3/UPDATE folder but my PS3 just won't find it. I have formatted my memory stick (Its in FAT32 as well), I've also used a second memory stick just in case mine was at fault.
It comes up with "No applicable update data was found"
In case anyone wants to know, I've entered service mode using PS3JIG on the PSP because that was on the only device i had to get my PS3 into service mode. So does anyone know how to fix this issue?
If I've left any details out feel free to ask.
