Network unlock unsuccessful with code

I purchased a network unlock code from a site ive used many times. I put in a different sim in and it prompted for a code. I entered the code it said it was unsuccessful so i tried it again with same outcome. I read about having to use *#7465625# to unlock it so i tried that with no results. I figured if i flashed back to stock maybe those codes would work but that didnt make a difference. Now it no longer prompts me to enter an unlock code but will not register on the network. Ive read that it may be frozen but im not sure how to enter the unfreeze code. Can anyone help me please?

Did you get any codes other than the sim unlock code? You'll need a complete set of codes to unfreeze the phone asit is probably hard locked at the moment.
What phone do you have (i.e. i747 or i747m)? What stock ROM did you install on the phone?

Are you on Android 4.3? If not you just need to flash the 4.1.1 radio to free unlock the phone. By the way, i heard that after 5 failed attempts of inputting the network unlock code your phone will need a master unlock code to unlock.

Im on 4.1.1 but would like to use a custom rom will that affect it? Ive read that it may be frozen after 3 unsuccessful attempts but I dont think i entered it 3 times. I do have a defreeze code aswell but how do i enter it?

Are you on completely stock 4.1.1, including the bootloader? If you are, did you try unlocking the phone using the free method from here: http://forum.xda-developers.com/showthread.php?t=2176719 ?

No i have clockworkmod but its been so long I forget how to uninstall it though Ive figured it would help me unlock it. Ive read that free unlock doesnt work on all custom roms plus I already have the code so i might as well use it

I have the i747m with 4.1.1 and clockworkmod. Also I have network, provider, subprovider, defreeze codes.

Did you try any of these methods: http://www.mobileunlocked.com/samsung-instructions.asp ?

haha yes Ive tried them but those codes do nothing when I dial them in. Only code that works is to get the imei and *#197328640#.

I recently bought 2 i747M, one comes with 4.1.2 and one comes with 4.3.
For the 4.1.2, I just need to flash back to the 4.1.1 stock radio (the ROM is still 4.1.2), then I just follow the instruction below:
http://forum.xda-developers.com/showthread.php?t=2024514
(You need to be on stock rom in order to have the dialer code working)
For the 4.3, I play it safe and bought an unlock code for it which works on the 1st try.

[Q] Note 3 Rooted, Tried Unlocking, Unsuccesful at all attempts

Can someone please help me? I have rooted my Note 3 and have tried SIM unlocking it with CHainfires region unlocker as well as the one where you enter the *# number. None of them have worked. I am at a loss. The one with Chainfires app tells me it is done but when I reboot it it still asks for unlock code. THe other way with the *# number, none of the options are in the menu that I am supposed to be able to access. PLEasE help. I am going crazy here.Thanks in advance.

Cannot unlock after upgrading- pattern

I upgraded to MM v20c and had a pattern unlock set - since then I can no longer unlock. I even went to Android Device Manager and set a code lock - but still can't unlock. I have some important info on the device and do not want to reset the system. Is there any way to do it?

Just to add - I do have access to my gmail, so if there is a way to reset the lock screen do let me know.

Using ADM I can again "lock" the device but dont get a prompt to enter the code. I can also make my phone call another number - but there seems np way to unlock it. Any help will be appreciated. Thanks!
EDIT: There is no option to enter the code from ADM anywhere.
EDIT 2: I can use adb

Bootloader unlocked how can we now access Service\Diag menus?

Hi thanks to the wonderful Devs im bootloader unlocked.
I need to access Service codes for diag for fingerprint scanner and a couple of other bits to test.
How can I access them, they are still locked out. Do I need to edit a system file to unlock this feature that Verizon locked out.
Thanks

Change this file:
Code:
/efs/Carrier/HiddenMenu
from OFF to ON

Thanks Mate that worked fine.

Sorry to revive this thread but once we set the HiddenMenu to ON what is the correct code to get into the hidden menu?

try thi code *#0*#

Yep, that did it thanks.

Hidden menu question?

Was able to access the hidden menu using the dialer code posted by another user, 5689#*992#.
Under Device Test, there are two options. SAAT and Flash Lock.
What is Flash Lock? Mine is set to UNLOCK.

Bump;
I would also like to know. Switched from LG G3 to G5 yesterday... long story but the phone is already on 7.0 (NRD9OU) so can't do the ADB root. Fingers crossed that we can gain root.

I have the same question, google lead me here with a search lol.. I was curious too, does this mean we can flash it without actually rooting it ?
