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! :good:

Mod Edit

In order to get this to work ,you need modem ME2... follow this :


Finally I managed to sim unlock my phone after 10 days of experiments



I have a Samsung Galaxy S4 GT-i9505 LTE with Android 4.4.2 bought from France (XEF):
  1. I rooted my phone using CF-Auto-Root
  2. I flashed with Odin the ME2 modem only (XXUAME2 for my case) using the CP/PHONE bouton - find the list in this thread
  3. I used RegionLock Away as described in this post

Thanks to all members of XDA

yes it did...

all 5 times i tried it done exactly what it said in the guide but didnt unlock

Hmmm... We have confirmed successful unlocking reports from Philippines, Hungary and UK users. I don't know why you can't unlock yours. So far only the I9505 have been tested. Bytheway, mine has a MDM Version. Whats yours?

To those who successfully unlocked their i9505 using this method, what rom version are you on?

I'm from Hungary, the i9505 from T-Mobile and need to unlock. Followed the instructions but got this at the end:
"Back-up not exist [First you must make Back-up by using [3]menu]"

Cheers, Joe

I create a post in spanish forum some days ago about unlock i9505.
Some user reports work well, but some users reports not work.
The thread is:
Code:
http://www.htcmania.com/showthread.php?t=607799

I have an orange locked i9505 and unlock only with sha256_enable_off. Not needed to use NV Rebuild.
But some vodafone users can't unlock his phones. They try all steps, include NV Rebuild/Restore Backup and NV Rebuild/Load default NV, but phone still locked. They are on I9505XXUAMDN...
I don't know what is the problem...

    working on my o2 uk, i can use my three sim now, thanks

    you're welcome... a simple THANKS will do...



    should i have any sim inserted ? or without sim?

    you can do it with an accepted sim inserted or you can try inserting a non accepted sim, when greeted with the ENTER UNLOCK PIN just press dismiss then follow the steps.
