[Q] Need help to access UTMS screen

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:

Is there a way to require pressing the enter key after entering your password / pin to unlock your phone.
Right now as soon as i enter the last key the phone unlocks automatically. I'd like to have to press the enter key.
Thanks
Hi!
I was looking for the same feature as you, but could not find how to disable quick unlock. From the changelog thread:
Anu6is said:
Keyguard quick unlock
Device Type : ALL
Default : ALWAYS ON
Location : ---
Description : Automatically unlock the device once the correct PIN is entered.
Removes the requirement to select submit.

Always on, and no setting available in the Settings to disable.

Network lock menu from service mode?

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
might have to see if there is any option for KIES.....
.....no wonder why people already buy them unlocked...

No IME number assigned or service menu accessible

Hi,
My wife got a test model from her friend who worked for Starbuck. The phone can with the original box and valid IME number, but Verizon can't assign the Number to the phone. The rom seem to be lock and can't access the service menu either.
Can I flash a new ROM on it? Will this give me access to the system and access the service menu?
Any help would be much appreciated,
Peter
