Black screen when booting the ps3 3.15

[linformatitien]

Hello.
I'm having problems when booting my PS3 I have a 3.15 black screen after boot on the key.
I modified the config.h and makefile.
Then when I compile 3.15're no error.
What are the files to be modified to compile in 3.15
Thank you.

I guess your problem is return incorrect jig_response data. The demo project of loaderPL3 is only for 3.41, and return jig_response for 3.41 firmware. You can change it to PL3 jig_response and try it.

I downloaded version 3.15 of pl3 then changed the makefile and config.h, no error when compiling, but I're still no display on screen.
What version of pl3 should I take?

Not sure if this would work, Ill test it when i have access to a 3.15 ps3, but could you test editing psgroove.c finding the line const u8 jig_response[64] = { and changing that section to either

const u8 jig_response[64] = {
0x80, 0x00, 0x00, 0x00, 0x00, 0x3d, 0xde, 0x38, 0x80, 0x00, 0x00, 0x00, 0x00, 0x3d, 0xde, 0x48,
0x80, 0x00, 0x00, 0x00, 0x00, 0x33, 0xda, 0x10, 0xe8, 0x83, 0xff, 0xf0, 0xe8, 0x63, 0xff, 0xf8,
0xe8, 0xa3, 0x00, 0x18, 0x38, 0x63, 0x10, 0x00, 0x7c, 0x04, 0x28, 0x00, 0x40, 0x82, 0xff, 0xf4,
0x38, 0xc3, 0xf0, 0x20, 0x7c, 0xc9, 0x03, 0xa6, 0x4e, 0x80, 0x04, 0x20, 0x04, 0x00, 0x00, 0x00,
};

OR
const u8 jig_response[64] = {
0x80, 0x00, 0x00, 0x00, 0x00, 0x3d, 0xde, 0x38, 0x80, 0x00, 0x00, 0x00, 0x00, 0x3d, 0xde, 0x48,
0x80, 0x00, 0x00, 0x00, 0x00, 0x33, 0xda, 0x10, 0xe8, 0x83, 0xff, 0xf0, 0xe8, 0x63, 0xff, 0xf8,
0xe8, 0xa3, 0x00, 0x18, 0x38, 0x63, 0x10, 0x00, 0x7c, 0x04, 0x28, 0x00, 0x40, 0x82, 0xff, 0xf4,
0x38, 0x63, 0xf0, 0x00, 0x38, 0xc3, 0x00, 0x20, 0x7c, 0xc9, 0x03, 0xa6, 0x4e, 0x80, 0x04, 0x20
};

EDIT: I tried both of these, both boot, and can run homebrew, but backup loading isn't working. I used this copy of PL3 as i was having problems with the newest version, perhaps backup loading is disabled here?

EDIT AGAIN: I was using an old version of backup manager on the 3.15 ps3, backups now work. Use the first code i posted, i will soon posted a compiled 3.15 update.bin. Here is the compiled version, enjoy.
