No I did not I ended up selling the phone as I wanted to change networks but I could not unlock the pjone.

Ei.. any fix for this?
i BELIEVE this is part of Samsung's "business strategy".. i was resolve this using the Samsung Service Mode apk (which I cracked and patched :highfive, however i have another issue related to this (see attached pic)!
In this case...may i ask if anyone from XDA knows the secret code for the UMTS Menu for me to access the Network Unlock menu???

RESOLVED thru SERENDIPITY!

Hi XDA Peeps!
I was able to unlock my i9505!
I just did the following steps:
1. Dial *#0011# via Phone Utility apk [Phone Connectivity Status will appear (via Service Mode)];
2. Tap on the left soft key (LSK) and select Key Input > Enter 1 > Hit OK;
3. Tap on the LSK and select BACK [You're now just a few steps away!];
4. Tap on the LSK and select Key Input > Enter 1 > Hit OK [Your screen shall have a different output now (i.e., a single digit "1" on line 1)];
5. WAIT for 5 seconds until the UMTS MAIN MENU appears > Select Debug Screen > Select Phone Control > Select Network Lock;
6. Next, tap on: [3] PERSO SHA256 OFF;
7. From here, go back to the UMTS MAIN MENU by tapping on Menu (left soft key on SGS4) and selecting Back from the options;
8. Once you are in the UMTS menu, tap on: [6]COMMON;
9. There, select: [6]NV REBUILD;
10. Now in the NV Rebuild menu, tap on: [4] Restore Back-up;
11. Samsung Galaxy S4 will now go into a temporary freezing state. After a while you’ll see some activities. The screen will be black and the LED will turn Blue. The Menu and Back key button on phone will also light;
12. Lastly, your Samsung Galaxy S4 will reboot automatically and will take a minute or two in booting up (depending on your ROM's Boot Animation);
BOOM! Your Galaxy S4 GT i9505 is now SIM-unlocked! Try a SIM card from another carrier to confirm the process and do not forget to share this to your friends too!

Where should I go in this menu? Selected the first [1] menu, now the phone starts "Blocking mode" what's this???

First hit menu then back. Then I hit menu-select-4 and and then hit menu then back and it gives me a list of options. Never messed around in there but I just looked around to see what was there. I tried 1,2,3 and phone just rebooted but nothing really happened.

Hm...
I do *#9090# and see:
DIAG CONFIG
[1]DM/DUM over HS-USB[]
[2]DM/DUM over HSIC[]
[3]DM/DUN/RmNET over HSUSB[]
[4]DM over UART(*)
[5]DBG MSG ON(*)
[6]DBG MSG OFF(*)
Could someone check what the defaults are?
Ok did the sequence and found it
What is "blocking mode enabled"? Did I push something wrong?

These are what I see

Tried it and it didn't work after put in my tmobile sim.

Tried it and verified that Perso SSH 256 was off and when i popped another carrier sim, it still said sim locked. Caved in and purchased the unlock code form cellunlocker.
p.S: Don't forget to switch Perso SSH 256 back to ON if you want to unlock it via cellunlocker code

Tried it as well and didn't work. So used unlock code.
Thanks @mikron15 for letting me know to turn SSH 256 back on as I was getting unlock unsuccessful.

tried it as well with no success... any other suggestions?

How to SIM unlock Samsung Galaxy S4 SGH-M919 (tested - works)
Hi Everyone,
I'm a long time lurker and benefited greatly from the postings here at xda.
So I'd like to contribute something back.
After trying many methods and reading all the posts in the various S4 forums, I finally found a way for SIM unlock that works for me.
I have tested it, and it works on my T-Mobile S4.

KaneHusky's post for the dialer code
This thread on how to unlock
chavxxx's post pointing to the right final step
Here are the steps:
Goto phone dailer, and enter *#27663368378# for the debug service menu.
In "ServiceMode", select [1] UMTS
In "UMTS MAIN MENU", select [1] DEBUG SCREEN
In "DEBUG SCREEN", select [6] PHONE CONTROL
In "PHONE CONTROL", select [6] NETWORK LOCK
In "NETWORK LOCK", select [3] PERSO SHA256 OFF
It should show:
SHA256_ENABLED_FLAG[1]
SHA256_OFF => SHA256_ON
Now touch the first line SHA256_ENABLED_FLAG[1]
It should show:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 116631
Now press the menu button and select "Back"
It should show:
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
Again, press the menu button and select "Back", and you're back in the "NETWORK LOCK" screen
Press the menu button and select "Back", and you're in the "PHONE CONTROL" screen
Press the menu button and select "Back", and you're in the "DEBUG SCREEN" screen
Finally, press the menu button and select "Back", and you're back in the "UMTS MAIN MENU" screen
Select [6] COMMON
In "COMMON" screen, select [6] NV REBUILD
Now you are in the "NV REBUILD" screen, you should see the following text:
------------------------------
Golden-Backup exist
You can Restore Cal/NV
------------------------------
Now for the final step.
In "NV REBUILD" screen, select [4] Restore Back-up
The button lights for menu and back should come on, and the phone will auto reboot in a few seconds.
Note: chavxxx's post of selecting "[1] Load default NV" DID NOT work for me.
Congratulations, your phone is now unlocked.
Stick in a sim card from a different carrier and try it out.
Please post followups of your experience with this unlock method.
Thanks, and good luck!

Can't verify with the SIM card yet but the sequenses worked for S4.
What are the additional steps for S3?

I can't test because I got my sim unlock all ready by paying 25 for it when the phone came out

Network unlock: [3] PERSO SHA256 OFF missing

Hi,
I have rooted MK2. I am trying to follow the steps http://gs4.wonderhowto.com/how-to/carrier-unlock-your-samsung-galaxy-s4-so-you-can-use-another-sim-card-0148110/
To get to the menu, I'd have to use the instruction at the bottom
*#0011#
Menu > Back
Menu > keyInput "Q"
Menu > keyInput "0000"
Wait for few seconds
However, when I get to step 6, option 3 PERSO SHA256 OFF does not exist. It only has 2 options:
[1] PERSO SHA256 Info
[2] RAT_FREE_SUPPORTING ON
How would be able to turn network lock off?
Thanks

And now I should see three options:
[1] Perso Sha256 Info
[2] Perso Sha256 ON
[3] Perso Sha256 OFF
But options [2] and [3] are Hidden.
¿Hoy to "unlock" these options for going on the Sim Unlocking proccess?
Thanks a lot for your responses!

s5 unlock question?

hi guys so i found on androidorigin this :
– Insert the new SIM card into the Galaxy S5
– Turn the Galaxy S5 off and then turn it back on
– Open the Dialler application, and type in *#197328640#
– Then select [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3] Perso SHA256 OFF
– After all this, you will need to wait about 30 seconds before pressing the back button
– Now that you’re back at the main menu you should see a Network Lock message
– Now select [4] NW Lock NV Data INITIALLIZ
they say saying that this will unlock your s5 so i can use any provider, is this true? dose it work??
