Hi Guys,
Thanks for the help in advance. I just want to ask if anyone experience issues unlocking galaxy s3 mini gt-i1890L from telcel Mexico. When I put a different SIM and restarted thr phone. It only tells me "Network Lock". It doesn't show any fields to enter unlock codes. I factory reset in phone and kies as well as reload official samsung firmware and no luck. I tried entering codes to initiate unlocking but phone does not respond to any codes. I can only check imei and go tk service menu. Check the picture. Any help is greatly appreciated.

You said you tried entering codes to initiate unlocking (how many codes do you have) if you enter the wrong code too many times your sim will be blocked and you wont be able to use it and will have to get a code from the sim provider to unblock it.

Hi there,
What I meant when I tried to initiate the unlocking sequence, I dialed these numbers and nothing works. The phone doesn't respond to any of it. I pressed the dial icon but it just says "Not registered to network". For some reason when I insert a different SIM Card and restart the phone. It comes up to a screen saying "Network Lock" and that's it. It doesn't even allow you to enter unlock codes. All you can press is "Dismiss" Like what I showed in the picture. I don't know how to enter the unlock codes anymore since the phone will not respond to any of these service menu codes but it does respond to *#197328640#.
Method #1 Insert a Non accepted SIM card in your phone and power on. Once finished loading your phone will ask you to enter a code, enter the Unlock Code
Note: Non Accepted Simcard is any simcard not from the original provider
OR
Method #2 Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)
OR
Method #3 Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE# (8 digit unlock code)
OR
Method #4 Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.

I tried these service codes as well and no luck
*#7465625# = Check the locks.
*7465625*638*Code# = Enables Network lock.
#7465625*638*Code# = Disables Network lock.
*7465625*782*Code# = Enables Subset lock.
#7465625*782*Code# = Disables Subset lock.
*7465625*77*Code# = Enables SP lock.
#7465625*77*Code# = Disables SP lock.
*7465625*27*Code# = Enables CP lock.
#7465625*27*Code# = Disables CP lock.
*7465625*746*Code# = Enables SIM lock.
#7465625*746*Code# = Disables SIM lock.

Can you start the phone with a sim from the correct network?

Yes, I tried both. I have the original Telcel SIM card and other SIM cards. The phone just doesn't respond to any of the service codes to initiate unlocking. Only message I got was "Network LOCK" and a picture of a padlock and a button that says "DISMISS"

I am not entirely sure, but it is probably the same case as my Galaxy Ace a few years ago. Unfortunately, Telcel adds an additional lock layer that is embedded in the ROM, so any effort does no good. What I did to unlock it, was download another firmware from Sammobile that was compatible from another carrier. You may choose that path, or flashing a custom ROM. Obviously, this implies you must have root permissions enabled on your mobile device.

I have the exact same problem with the Galaxy S3 mini from Telcel. Even at professional unlocking businesses this was a problem.
Their is just no option to enter unlock codes, neither does it respond to "Method 1-4 unlock codes"
After entering *#197328640# in the keypad the options are
[1] Debug Screen
[2] Version information
[3] common
After selecting [1] debug screen, there are 8 options
[1] BASIC INFORMATION
[2] MM INFORMATION
[3] RR INFORMATION
[4] NEIGHBOR CELL
[5] GPRS INFORMATION
[6] SIM INFORMATION
[7] HANDOVER
[8] PHONE CONTROL
Phone control has 7 options
[1] DRX CONTROL
[2] FAKE SERIAL CONTROL
[3] NAS CONTROL
[4] UE STATE CONTROL
[5] SIMULATION
[6] NETWORK LOCK
[7] NETWORK CONTROL
and network lock says Not Active.
I bought a cheap $20 phone make and receive calls but if their is away to unlock this thing that would be greatly appreciated.
I would rather avoid installing customs ROMS however i can root and unroot with VROOT. So if there is some .apk that needs to be modified or something that would be a better option. If anyone can help with this issue, it would be greatly appreciated. Thanks..

I also got this info at a code unlocking site.
*Note regarding Samsung Android phones:
If your phone is locked to Telcel or Claro Mexico or Claro
Worldwide, before placing your order please try inserting
a non-accepted sim card into your phone and ensure you
receive a prompt to enter the unlock code.
If you do not, you may need to either root your phone or
change to the latest North American firmware prior to
placing an order as you will not be able to enter an
unlock code until the firmware is updated.
The phone originally came with jellybean 4.1 but was updated to 4.1.2. Dont know if that has anything to do with it

If you are in AOSP based rom, those code won't work. You need to use some script to enable it.

i am on pure stock 4.1.2 rom and which scritps can you give me?

so you're on stock, I think you need to find a correct code..since I never put my device into dm mode, I never tried anything about it. I'm sorry for the script, I can't help you..search it on xda..

is DM Mode Download Mode? If yes, hold the power, home and volume down buttons at the same time while booting up your phone.

try ##DMMODE# (##366633#), that works for the Verizon version anyway

Not working on SM-N910F, tried *#197328640# and nothing happens?

Looks very much like what I did to unlock my S3 quite some time ago, it worked but only on Android 4.1 if I remember right, anything above that and an option was missing from the hidden menu so you either had to roll back or use another method.
Can anyone confirm this works (I would try but I don't have an alternative SIM)?

Not working here either. European SM-N910F

Shouldn't make any difference, I think the point is to prompt the SIM unlock code box.
I used a 3mobile sim in an EE locked 910F and that sequence of numbers brings up no such menu, I'm pretty darn sure this doesn't work on any variant because as pointed out above.... Samsung locked this out ages ago, in fact it was a surprise you could do it then!
However, I'm all up for being proven wrong, proof please.

So I just found this to get into the service menu - http://forum.xda-developers.com/note-4/general/enable-servicemenu-galaxy-note-4-hd-t2919157
If anyone can find a sim unlock method via that then brilliant but I doubt it!

Looks like a copy and paste from the S3 and Note 2 Thread. It's exactly how I unlocked my old S3 but it only worked on android 4.1.1 and was locked out in the next update.
This does not work on our Note 4.

I don't see the same menu

If the phone gives you the MM06 code it is reported stolen, therefore it will no longer connect to any network carriers. You will have to have the IMEI cleaned. That is all I can say.

I have tried this but unfortunately i do not get the options on my n910t, i am trying to use it in Malaysia and it was brought from USA, anybody can suggest me anything please to get the sweet phone working again. thanx

There are a few caveats here. It doesn't matter if you have a sim card in or not when unlocking a phone via this method. You only need a sim from a different carrier to test it, although there is a GSM code you can enter on the phone pad to bring up the screen to enter an unlock code manually. You do not need that or even any sim card in the phone for this service menu method.
Simply
1) Enter *#197328640# on the phone dial pad
2) Select [1] UMTS
3) Select [1] Debug Screen
4) Select [8] Phone Control
5) Select [6] Network Lock> Options
6) Select [3] Perso SHA256 DFF.
7) Go back one menu "Network Lock"
8) Select [4] NW Lock NV Data INITIALLIZ
9) Wait a few seconds, depending on your phone reboot.
If you can't bring up the service menu on step 1 try to dial *#22745927 to enable hidden menu...press back...then dial *#197328640#
Another caveat is that this only works on certain firmwares. Im running Maximum Overdrive 7.1.1 and the debug service menu is empty. See attached screenshot. For example on the Note 2 the only firmware i could find with the correct service menu is the very first original firmware release android v4.1.1 T889UVALJ1:_(4.1.1) (11/02/12) I had no issue downgrading from v6.0.1 and back again. You can put a custom rom back on, or whatever you want after you unlock the device as the changes are made in the NV memory and it is unaffected even by wiping out any and all of your file systems. You will simply lose access to those sections of the service menu with most custom or newer roms you flash but you should be easily able to bounce around via Odin with ease on the Note 4 AND 2.
