Hi,
Got this spaking i9505 s4, but it seems the *#197328640# service mode is missing, im using this mode to select wcdma band, In my S2 it is there.

Also *#2263# is not working
Thanks,
Roy

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???

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.

Could someone check what the defaults are?
Ok did the sequence and found it
What is "blocking mode enabled"? Did I push something wrong?

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.
Credit to these posts:
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!

[Q] Question regarding S5 - G9009D Dual Sim

Hi.
I have just brought from China a G9009D Dual Sim Galaxy S5 and just now I realized that it has a "China Use Only Sim Slot - CDMA".
I am from Brazil and I was wishing to use 2 different numbers on it (3G).
Is anyone researching if there a way to change this? I.e: Make both Sim card slots 3G and Quadband?
Thank you!

Anyone can help?

You probably can't do that. Only one slot is GSM, the other is CDMA. You'd need a different model to support two GSM numbers.. the sm-900fd duos appears to have dual GSM SIM slots.
In any event, there is a thread that collates all of the information on the Chinese model that you have. Do a search and look for details there. You'd also find a better audience for your model as the people in that thread have the same goals and model as you.
.

I unlocked my s5 sm-g9009d
Here is the solution
1- In the dial pad, enter "* # 0011 #", will enter ServiceMode interface (if no response, just wait a while and try again)
2- Click on the top right corner of the three-point menu, press Click "Back", then click on menu, select "Key Input", enter a capital Q, point "OK", and then point to the menu, select "Key Input", enter "000000", click "OK".
3- patiently waiting for 5-10 seconds, will enter the "Main Menu" menu, click "[2] UE SETTINGS & INFO", "[1] SETTING", "[1] PROTOCOL", "[3] CDMA" , "[9] CTC SIM LOCK", "[1] SIM Lock", "[2] Disable SIM Lock is"
4- when you see the future "SIM Lock is Disabled", turn off the phone, insert your UIM in slot one.
It should work now

Where did you get this 15-step instruction?
May be it is for another device or model? My Note 3 is also the same as your.
And please be noted that playing around with these "hidden menu" is very dangerous as it may mess up your device, so be careful and only do things that you fully understand.

[Q] Note 4 SM-N910S (SK Telecom) issues. Need solution!

Hi all,
I am a bit new to this forum. So my apologies for any tips that i have not known yet
I got a note 4 from SK telecom KR (SM-N910S) unlocked verion running Octa core version. There are 3 issues currently exist on my phone. I am living in Australia btw.
1 : Every time the phone start up, it will ask me whether i want to enable networking or not and talking about roaming ??
2 : Sometimes MMS can not be sent, retry few time and its ok ?
3 : The networking on SM-N910S has a big issue for me, that model only has 2 kinds of network LTE/3G mode or 3G Only mode, on AU version we have GSM/WCDMA/3G/LTE etc so it look like i am missing WCDMA and 2G networks
My question is :
* How can i access the hidden menu for Note 4, i know there is a hidden menu somewhere on that phone allow me to change network mode
* Can i flash my phone with AU firmware to remove roaming message and other SK's stuffs. ??
I can list some of my phone info here

i use n910s sk telecom too and get frustated how to connect to lte band 8, already set to lte preferred and still the icon shows me 3g.
but then i found the solution from xda developer, i forgot the links but i take screenshot of it.
now i can connect to my lte network and explore my n910s network by entering secret code for sk telecom.
NB: you don't have to root your n910s to explore this menu.
here's the screenshot:

Not working
Hi,
For me is not working. I did that change, I have LTE connectivity (not 4g as I have on my note 3) but now I can't use the phone, only Internet. Any idee? I'm on Vodafone Romania.

4G and LTE is just preference in naming. If you choose 'LTE' option without 'preferred', it will fail to fallback to 3G to make a phone call. Different story if your carrier has VoLTE

note 4 hidden menu network settings
I got this note 4 off ebay and it kept wanting to roam, and not use my network preference. I went into the hidden menu and changed it to all LTE and it asked if i wanted to use my network data and i said yes. Fixed it and the roaming "r" went away, but......................it won't stay like this after you reboot the phone, it goes back to roaming again until you go back into the hidden menu and do it again. How can you get it to stay permanently?
