I have SM-G9650, perhaps it is different in SM-G965F/DS
On S7 and S8, the code *#27663368378# would access the menu for looking at CA combinations, and enabling which CAT level the phone is capable of. Different CSC allowed for different combinations. Starting from S7, this menu was disabled and needed adb to boot on the SM-G935F.
On the 9650, I cannot get this menu at all. I do not know if 965F can access it instead.
On any S9+, how do I access this menu with the code disabled?

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.
I have a Samsung Galaxy S4 mini GT - 19195, I try different methods, and google this phone model with secret codes to access the UTMS screen, but none of them work.
I try *#0011#, it didn't work.
I try *#9090#, it only took me to USB debug, and DBG msg on or off options.
What other codes I should use to access the UTMS screen, then access to phone control, and network unlock? Any instructions you can give me?

You could try the app "service mode shurtcut"
most of the functions only work on stock
thanks
Finally it works.
After I enter the service mode, I hit [MENU] + [BACK]; then [MENU] + [KEY INPUT] + Q; then [MENU] + [KEY INPUT] + "0000", then I enter the service menu eventually.
Thanks guys!:good:
Does anyone know how to get to the network lock from the service more for a sm910a?
i bought a unlock code from the celluar unlock.net..failed...didnt get any PUK error so all good there
ive tried numerious ways of entering the defreeze code and call that still failed... now they want me to do a factory reset and i dont want to do that just yet...
Ive done the non att sim trick...ive done
The following code brought up the network unlock prompt #7465625*638*# tells me unlock cone is sucessful
im trying to get to the network lock function through the service menu. Ive tried :
· Dial *#197328640#
· Press the Menu > Back > Menu
· Open the Key input and enter 1, then press OK
· Press Menu > Back
· Press UMTS > Debug Screen > Phone Control > Network Lock
· Press Options > Perso SHA256 OFF
· Press Menu > Back
· Press COMMON > NW Lock NV Data INITIALLIZ
· Your Samsung Galaxy Note 3 is now SIM unlocked
None of that above gets me there:
This takes me to the debug screen but from there I cant get to the network lock:
Do the same for *#197328640#. That will open the Debug Screen.
service mode *#27663368378#
*#6328378#
One thing I havent tried is because the phone is ATT but I have it on a Straight Talk SIM for the BYOP is to go into the APN settings and switch it from the Straight talk APN settings to the ATT Nextgenphone option and then prompt to do the sim there... NEVERMIND DID THAT AND IT FAILED
Any ideas guys??
Ive read place online to unlock it via usb cable but it says it wipes the data so im wondering how that works

hello i have a s8 edge how can i get access on network lock menu?
Root work with kingroot 456
I've spent 3 days trying to enable GSM and LTE bands in my Swift following this guide from here. But when I try to use the QPST, the software does not recognize my device.
Does anyone knows the secret code to enter in the USB Settings? I've tried a lot of them but without success.
My steps were:
Unlock the OEM - check
Install CyanogemMOD 13 (6.0.1. Marshmallow) - check
Enable Developer Options and enable debugging and Root Access (I couldnt install SuperSU coz I got bootloop twice) - check
Access to USB Settings to change from AP to CP - uncheck
Does anybody knows how to proceed?
I'm from Brazil and I really need to add new bands to get a better signal reception for GSM and the right band for LTE (700Mhz).
Anyone?
I just need the secret code to enable the usb settings.
The problem was my carrier and not the phone.
I've changed the carrier and boom... 4G working nicely.
My Galaxy S7 Active just went to the dark side yesterday. (and is not even May 4th yet).
Found out phone itself is still kicking. I can call it it, but answering is very tricky.
Went on the start ADB to recover some of the data of it, images, messages, ....
but darnit, not my lucky day: USB developer option is not enabled.
Doing some more research I found this thread:
androidDOTstackexchangeDOTcomSLASHquestionsSLASH12834SLASHbroken-screen-while-debug-mode-was-disabled-how-can-i-re-enable-adb
This requires to get the Samsung S7 active into recovery mode, by using the 3-finger salute on the phone.
To enable recovery mode on the S7 you first need to power down the phone. Since you can't see the screen, the easiest is to force power down:
a) press VOL-down and power key for 7+ seconds and wait a while
b) then press VOL-up, home and power key all simultaneously. When you see a blueish line text flashing up, release all key
sit back and wait a while while the phone boots up in recovery mode.
Finally a menu will show up allowing you to select various different options, which can be selected with the VOL-up and -down keys.
I worked all this out with another older Samsung phone running , different model and older version of Android.
My 'broken' Galaxy S7 Active is running Android 8 (oreo?), maintained and updated by the AT&T automatic DFU process.
On all the Samsung phones I've looked so far the number of option and order in the recovery menu is slightly different.
Since the display is broken I can't see what is available. And I want to make sure I do not identically select the ' clean and wipe' option.
Could someone please post a pic of recovery option menu from an S7 running Android 8.
Not sure if it matters: could the Active model be different?
thanks in advance that would be really helpful.
