    Post [All BL] Hard-coded BL-only unlock with stock BB possible?

    It is my understanding from reading the IPSF methodolgy papers and geohot's technical explanations that a hard-coded unlock based on bootloader modifications only is possible. If the bootloaders are responsible for validating tokens, then a neutered BL which validates all tokens would be a hard-coded unlock. The stock baseband could be reflashed at will, and would not require patching.

    If I am correct, is there any reason this has not been implemented? Are there ramifications I am not thinking of?

    A hard-coded BL-only based unlock would be restore-proof, and theoretically work with all future basebands -- not even a string-search & 4 bytes of zeroing would be required.

    Comments from MuscleNerd, grey or other DevTeam members?

    I would also love to know more about this. My understanding of it, and I am probably wrong, is that patching the baseband makes it unlock without running "AT+CLCK="PN",0,"00000000" after each boot.

    As far as I know the current baseband patches simply skip the MCC/MNC check.

    We need a Dev or Geohot on this particular question....
