So here an tiny little update. I used elser1 BLES01329 EBOOT.BIN, because he provides us the original one + I got the Update.
Original EBOOT.BIN = 10.283.388 Bytes
Firmware Version needed : 3.72
Update EBOOT.BIN = 10.320.432 Bytes
Firmware Version needed : 3.60
When I try to extract the original EBOOT.BIN with fail0verflow unself tool, I get the message "self_decrypt_header failed". On the other side, when I try the same with the Update *.PKG, I get this one "invalid type: 00000008".
So both of them are higher versions than 3.55 (we got those key's). But I get other error codes while using it. Do they changed the whole algorithm in between 3.60 to 3.72 or why I get other error codes ?
