[Q] Cannot get to Service Mode menu

Hello
I'm hoping someone can help me with this problem. I need unlock phone as I am moving in a few weeks and will need to use a new sim card. I have an unlock code but it is not working and I believe the reason is a while back a tried the free unlock method that has been online for a while and I was able to follow the steps fully (it didn't work to unlock my phone).
Now trying to follow the same steps again, I cannot where I enter *#0011#, choose back from the menu, then key input and enter 1. This used to bring me to the main menu but now it stays on the same page and does not change and I cannot access the main menu.
If somebody knows how to access the main menu a different way or fix this problem I would be very grateful :fingers-crossed:

How to fix samsung s4 thats not accepting network unlock code after free unlock
So I finally got it working. So i'll post this in case it helps some else having this problem.
You need to flash an earlier version of the firmware to allow you to access the main menu in service mode
I went to this forum http://forum.xda-developers.com/showthread.php?p=39176955
and downloaded the odin v3.04 program and then the XXUAME2 modem from the list.
Then after installing odin I chose phone, chose the extracted .md5 file from my computer and connected my phone to the computer using the usb.
Turn the phone off then switch it on whilst simultaneously holding the volume down and home button and then use volume up to confirm.
Click start on odin and wait for a few mins until the box at the top changes to pass.
Follow the rest of the steps stated in the forum above
After the flash, follow the instructions in this video https://www.youtube.com/watch?feature=player_embedded&v=cY4LcdO2WAE
Restart the phone with a locked sim and try the unlock code now, it should work.

Give this a try. You might have to figure out a new phone app dial number for step one as this is just copied and pasted (quite a while ago) from somebody on here i wish i could credit.
Step 1: Launch the Phone app on your Galaxy S4, and dial in: *#0011#
Step 2: Press the Menu button followed by the Back key. Then, hit the Menu button again and select KEY INPUT. Enter 1 and press the OK button to enter ServiceMode.
Step 3: Press Menu one more time and tap back again. This will pull up the Main Menu for ServiceMode. Tap [1] UMTS.
Step 4: Now select [1]DEBUG SCREEN, followed by [6] PHONE CONTROL.
Step 5: From the next screen, pick [6] NETWORK LOCK.
Step 6: You’ll get three options. Hit the one that says [3] PERSO SHA256 OFF.
Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.
Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.

[Q] How to unlock AT&T Samsung SGH-I337 Galaxy S4

When I get to Step 3, there is no option for [1] UMTS. Per the attachment, this is a far as I can go. Any help will be appreciated.
Step 1: Launch the Phone app on your Galaxy S4, and dial in: *#0011#
Step 2: Press the Menu button followed by the Back key. Then, hit the Menu button again and select KEY INPUT. Enter 1 and press the OK button to enter ServiceMode.
Step 3: Press Menu one more time and tap back again. This will pull up the Main Menu for ServiceMode. Tap [1] UMTS.
Step 4: Now select [1]DEBUG SCREEN, followed by [6] PHONE CONTROL.
Step 5: From the next screen, pick [6] NETWORK LOCK.
Step 6: You’ll get three options. Hit the one that says [3] PERSO SHA256 OFF.
Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.
Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.
Your device will now go through a series of “conditions”, where it will first freeze, then get on a black screen with Blue LED on and both capacitive buttons on, after which it will reboot automatically. The whole cycle might take a couple of minutes, so be patient. Once it powers back on, it’s network unlocked, permanently. Enjoy Folks ...

Phone unlock won't work

I followed this guide to unlock the phone
http://www.android.gs/sim-unlock-samsung-galaxy-s4-i9505-i9500/
1. You need to launch the Service Mode on your phone; in order to do that tap “*#0011#” in the dialer of your handset.
2. The Service Mode will be displayed; now you need to tap on “menu” (left soft key) and from the dropdown menu select “back”.
3. Press the Menu button once more and this time select “Key input”.
4.. Tap on the pop-up box that will be displayed; then enter “1” and tap on “ok”.
5. You now need to go back to the Service Mode menu; for that tap on “menu” and select “back”.
6. From the Service Mode menu, this time select “[1] UMTS”.
Click to expand...
Click to collapse
At stage 6.... there is no menu that says UMTS
It just simply takes me back to the original menu with stuff like "GSM900: Limited" etc
It takes me back to the very first menu after I dialled “*#0011#”
So.... what do I do...??
The reason I'm trying to unlock the phone is that it said, "Network not registered".... It won't let me connect to an EE network at all... so I thought maybe the solution is to unlock the phone.
Thanks

Is the sim activated? Could the imei be blocked by the carrier? If you are not bring prompted to enter a network unlock code, the phone could already be unlocked.

You should be asked to enter unlock code before yu try to unlock it.

In order for the service menu method to work, you MUST downgrade your modem to an Android 4.2.2 version first. Only then will you be able to access the appropriate menus. We have an entire thread on the topic of SIM unlocking in the General section of the forum, and mention of the modem downgrade really doesn't start showing up until posts from November, 2014. That thread has also pretty much switched to using RegionLock Away to blow away the SIM lock, as it's a more robust solution than the service menu method.
Now, will it help you regarding the EE SIM? Probably not. But it will allow you to use a SIM from any carrier.
