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 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 I9500 is now Sim-Unlocked.

Notable Feedback:

#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
