Thank you very much for your SCPH-30004R dump. This model has DVD Player version 2.10E, which is already available in the
project topic (DVD_PLAYER_VER_2.10E.ELF).
I think the SCPH-39003 has 2.13E, like the SCPH-39004. 2.13E is also available in the project topic, but I'm interested by your dump.
What method did you try to launch the dumper on your non modded 39003 ? Independence exploit (the TITLE.DB thing) or FreeMCBoot ?
Here is the PAL dumper in it's unpacked state. Maybe this one solves the problem :
