Slightly different to OP.I did this with my AUTHORISED Sim in first.1.

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! 6 Share this post Link to post Share on other sites
