    METHOD 2 - artnada

    This is what I did. Slightly different to OP.

    I did this with my AUTHORISED Sim in first.


    1. Dial *#0011#
    2. press Menu then tap BACK
    3. press the Menu again the tap KEY INPUT then enter 1, (wait a few seconds) it auto jumped into service menu.

    4. press Menu then tap BACK (not needed for me)

    Your are now in the SERVICE MODE MAIN MENU

    Tap [1]UMTS (may auto go into next menu (mine did)

    then [1]DEBUG SCREEN
    then [6]PHONE CONTROL
    then [6]NETWORK LOCK
    then tap [3]PERSO SHA256 OFF

    Go back to the UMTS MAIN MENU by pressing Menu then Back (several times)

    then tap [6]COMMON

    then [6]NV REBUILD (if this does not work next time)

    do [4]RESTORE BACK UP

    the device will freeze, black screen, Blue LED Light, Menu and Back key ON. Wait for it to reboot (about a minute).

    Your Samsung Galaxy I9505 is now Sim-Unlocked.

    Edit:

    When I booted back in with AUTHORISED sim, I had to turn off Mobile Data, then turn it on.
    I then turned off the phone, put my UNAUTHORSIED Sim in, booted back up and NO NETWORK PIN request!

    Again, I had to turn off Mobile data, then turn it back on. The UNAUTHORSIED Sim worked!!! 

    My previously locked to Three UK GT-I9505 is now unlocked to all networks  Thanks again to XDA (Y)

    It has been reported that this is indeed a "permanent" unlock:

    artnada's tests:

    I had sim unlocked my phone when I was on the "djemby" pre-rooted I9505XXUAME2-DEODEXED-KNOX-FREE-HD-VOICE

    I have just re-flashed my original factory Three ROM. I9505XXUAMDC_I9505H3GAMD6_I9505XXUAMDC_HOME and the Sim unlock was still UNLOCKED!

    I then re-flashed back to I9505XXUAME2-DEODEXED-KNOX-FREE-HD-VOICE.tar.md5 and the sim unlock was still UNLOCKED!

    So, I think we can safely say this sim unlock method is a permanent unlock!
