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

Unfortunately, I think you will need to unlock it every time after you do a factory reset. (unless someone comes out with a new rom, but I have not seen any development for the scl23; at least not that I know of)

Tap 3 dot on top right, Type "Q" (case sensitive) => Tap OK => Type "0000" => Tap OK

check your baseband it should be SCL23KDU1BNE4 in order to work..

How do I reach baseband ? Please explain

Unlock any SCL23 even @ 5.0
Hey guys, I've been following every unlocking threads for the SCL23 but no one seems to have the answer how to unlock ALL VERSIONS of SCL23.
I actually had mine for a year now and just decided to unlock it now, I have it on Andoid 5.0 which if you may know *#*# codes doesnt work anymore.
If you do some research, you also can't unlock SCL23 with Baseband ending with BNG3. Even if you're able to do the *#*#9090# code and followed the unlock procedure, it will not work!
Work around is:
1. Downgrade with ODIN to Android 4.X firmware version BNJ1 for SCL23.
2. Do the *#*#9090# Hack. Try *#*#0011# if you 9090 doesnt work.
3. Upgrade to latest firmware via ODIN
4. Profit
P.S.
I downloaded SCL23 Android 5.0 via SAMFIRM
and SCL23 BNJ1 from android firmware websites.
Hope this helps coz i tried going to different websites like vietnam ones! Most of the guides to unlock SCL23 are in Japanese so here's the source for one: http://mobilersidea.blog.fc2.com/blog-entry-45.html

[Q] Unlocking + Signal Issues post Flash and IMEI fix

Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!

I've still not been able to fix, but will update when I do in case it helps anyone else :good:

Access Service Mode Band Selection

Hello Guys,
my phone is unroot, brand new from 20.01.16.
Firmware is N920CXXU1AOK6

How can a access the band selection, so i can set to lte band 20 only.
The Code i found
*#0011# (works for access service mode)
More - Press Back

More - Insert 0000 (don't work)
also
More - Insert Q0000 (don't work)
More - Insert Q1 (don't work)
More - Insert Q0 (don't work)
The Code
*#2263* also don't work.
Has anybody a idea or a code how do can i access the band selection without root?
I tried with phone info, but also don't work.
thanks

Nobody have a idea?

I have tried all the codes I could remember that used to work and have had no luck.

I would like to know this too

Are you trying to set Band Priority? If you are, then you need to use ##DATA#.

https://mega.nz/#!ENIyhZqR!SWkbnmIV_FdWBWpVoF3JAOUPIB2sDivB7SjoZ5dPTc0 Flashing this firmware seems to enable service menu. Beware though as it doesnt support some sensors in S Health

Click phone then punch code : *#197328640# ->Umts->Debag Screen->Phone Control->Network Lock->Rat_Free_Supporting ON
After you click this you see " Now RAT Free Supporting". Click back button and try setting radio by pressing *#2263#.
RTA will lock back after restarting.
