[Q] US Cellular Galaxy SIII (SCH-R530U) on T-Mobile network

I ordered a Samsung Galaxy SIII (US-Cellular) on ebay and tried to follow the instructions below:
1. Type *#197328640# and it brings up the factory service menu
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off, Passed that is a screen that says something like "no options in this menu, current command is 11863", Wait for 30-60 secs, from there hit the menu button on bottom left of phone to bring up options, Select "Back".
7. The last command should have brought you back into the Network Lock menu, at the bottom is (4) NW Lock NV Data Initialize, Select it. You might be asked a saftey are you sure, some people not, after it begins that process wait a good 60 sec the reboot. Thats it! Phones Unlocked
Somehow the phone is not reacting on the USSD 'secret' codes. I can push the hash-button, but nothing happens. I found on a forum that I should root my phone. So I did through Odin. But superSU keeps crashing and I get the error: Security Notice, an attempt to access a secure area...
I don't really need a rooted phone, would be nice, but I would like to use USSD codes, like *#06# for example.

R530 is CDMA based and might not function correctly on TMo.
Also, USSD codes only work on TW-Based ROMs or stock. Root should have no bearing.

What you are trying to do is unlock the phone from US Cellular to use on T-Mo. If that's the case, you will have to downgrade the firmware to Android version 4.1.1. This does not require Rooting. You will see appropriate firmware on SamMobile.com. Try the same process after the downgrade.
Don't try the downgrade if you are on android 4.3. It will Hard Brick your phone.

[Q] Will this work to unlock ATT Note 2

I have a new ATT Samsung Note 2 with 4.3. With this I don't have the menu "NW Lock NV Data INITIALLIZ." So I need to find a different method to unlock. I found these instructions on the S4 forum for unlocking a Samsung Galaxy S4. I'm wary of trying it before getting opinions on whether or not it will work first. Has anyone tried these and been successful on a Note 2 or on other Samsungs than the S4? Also, if I follow this will the Golden Backup disappear and if so can I regenerate it?
Here are the steps:
1. Goto phone dailer, and enter *#27663368378# for the debug service menu.
2. In "ServiceMode", select [1] UMTS
3. In "UMTS MAIN MENU", select [1] DEBUG SCREEN
4. In "DEBUG SCREEN", select [6] PHONE CONTROL
5. In "PHONE CONTROL", select [6] NETWORK LOCK
6. In "NETWORK LOCK", select [3] PERSO SHA256 OFF
It should show:
SHA256_ENABLED_FLAG[1]
SHA256_OFF => SHA256_ON
7. Now touch the first line SHA256_ENABLED_FLAG[1]
It should show:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 116631
8. Now press the menu button and select "Back"
It should show:
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
9. Again, press the menu button and select "Back", and you're back in the "NETWORK LOCK" screen
10. Press the menu button and select "Back", and you're in the "PHONE CONTROL" screen
11. Press the menu button and select "Back", and you're in the "DEBUG SCREEN" screen
12. Finally, press the menu button and select "Back", and you're back in the "UMTS MAIN MENU" screen
13. Select [6] COMMON
14. 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
------------------------------
15. 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.

So can it be done or not?

Why doesn't anyone search? Look for a thread called free unlock. You're welcome.

Toshik1, I tried these steps for the S4 on my Note 2 and they did not work. I had all the right menu selections and it seemed to step through them as instructed. But it just didn't unlock. That may be specific to an ATT Note 2. Perhaps they would work for a Tmobile or some other carrier.
emeianoite, I did search for several days. The only free unlock steps I found specific for the Note 2 were for Android 4.1.1. Version 4.3 was missing a vital menu item. Folks said you could unlock if you downgrade to 4.1.1 first. Didn't want to do that. So I searched for unlocking a note 2 with version 4.3 and found these steps for the S4. Unfortunately as I said above, that didn't work either. Wound up paying for the unlock code.

Thanks! Sim unlock code was obtained from ATT, so it's only a question of properly rooting the phone with official 4.3 already in it.

Are you using a replacement battery? Not all are nfc capable. Also a case could block the signal, but you should still see the options.

Tmobile Galaxy Note 3 Can't Get / No GPS Lock After Lollipop Upate

My phone finally updated to Lollipop about 2 weeks ago and ever since then, I can't get a GPS lock anymore?
Things I've already tried:

https://www.youtube.com/watch?v=iUsXU28IDdM
https://www.youtube.com/watch?v=A1ntOfJS_1c
Reset & Download GPS assistance data using GPS Status app
My phone isn't rooted. I have no idea what else to do?

Here you go this is worked for me.
Open Phone, as if you were going to make a phone call and dial -
*#9090# (*#197328640# if that doesn't work)
Menu, select Key Input, enter Q
Menu, select Key Input, enter 0000
wait for the next menu. (It takes a while.)
UMTS->COMMON->NV REBUILD->NV REBUILD->SYSTEM->PROTOCOL->GPS->IMS
or, if you don't have UMTS:
UE SETTINGS & INFO->SETTING->SYSTEM->NV REBUILD->ALL
