Assuming you know C, consider this code:
https://github.com/grindars/android_hardware_samsung_freeril/blob/jellybean/libsamsung-ipc/SamsungModem.cpp

The boot process is IROM->PSI->EBL->SecureImage. Authenticity of PSI is 
not checked.
He has verified this by changing the magic constant 0xDEADDEAD and 
booting PSI.
Speaking about 0xDEADDEAD, it's a command ID which makes the PSI make a 
complete
RAM dump. So, then he has sent the modified command and successfully 
obtained a
dump.

The rest should be obvious from the source.
