Hi, i m again!
I changed my strategy. i red out the mbr of the player and run objdump on that. Is there an other step that i can make with it or is the assembly the end?
EDIT:
1. I red out the MBR and run arm-elf-objdump on that.
2. I cut off the header of my firmware and run arm-elf-objdump on that too.
Is there a arm disassembler or what can i make with that code?
how did you made it on other devices?

No comment?

objdump is a dissasembler, you can use the -D flag.
example: arm-elf-objdump -b binary -m arm -D myfile.bin
Bagder:
and there's no point in disassemblying the MBR, you should decrypt the mi4 and disassemble or you should disassemble the bootloader (which usually is unencrypted thumb ARM on the PP devices)

Ok thats the way i made it. I thought there is an other step to get C code out of that. Is there a datasheet for the commands?

I said it befor, i can t find any bootloader. Thats my problem and the reason why i red out the MBR. Also in the other files were no bootloader found. Are there other possibilitys?
