For sim unlock i have the combination but am missing a piece of the menu to complete the unlock

Can someone with a rooted note 4 try TrevE's logging test app pro version to get the secret codes it works on my stock rooted 3 with 4.4.2 and shows a bunch of dialer codes so it may work on a stock rooted note 4 on 4.4.4 ?

Hmmm, does the app at least work on a rooted note 4 ?

When you start the app you open the first top menu that says install package tools see first pic then select the top right tap see pic 2 then select find dialer codes and wait a bit and a bunch of system apps pop up see pic 3 then click on each app and the related dialer codes drop down see pic 4 hopefully this helps unless the app is just not compatible with 4.4.4 but there is a new version 14.5 out so make sure to update it hope that this helps.

[Q] Note 4 SM-N910S (SK Telecom) issues. Need solution!

Hi all,
I am a bit new to this forum. So my apologies for any tips that i have not known yet
I got a note 4 from SK telecom KR (SM-N910S) unlocked verion running Octa core version. There are 3 issues currently exist on my phone. I am living in Australia btw.
1 : Every time the phone start up, it will ask me whether i want to enable networking or not and talking about roaming ??
2 : Sometimes MMS can not be sent, retry few time and its ok ?
3 : The networking on SM-N910S has a big issue for me, that model only has 2 kinds of network LTE/3G mode or 3G Only mode, on AU version we have GSM/WCDMA/3G/LTE etc so it look like i am missing WCDMA and 2G networks
My question is :
* How can i access the hidden menu for Note 4, i know there is a hidden menu somewhere on that phone allow me to change network mode
* Can i flash my phone with AU firmware to remove roaming message and other SK's stuffs. ??
I can list some of my phone info here

Hi,
For me is not working. I did that change, I have LTE connectivity (not 4g as I have on my note 3) but now I can't use the phone, only Internet. Any idee? I'm on Vodafone Romania.

4G and LTE is just preference in naming. If you choose 'LTE' option without 'preferred', it will fail to fallback to 3G to make a phone call. Different story if your carrier has VoLTE

note 4 hidden menu network settings
I got this note 4 off ebay and it kept wanting to roam, and not use my network preference. I went into the hidden menu and changed it to all LTE and it asked if i wanted to use my network data and i said yes. Fixed it and the roaming "r" went away, but......................it won't stay like this after you reboot the phone, it goes back to roaming again until you go back into the hidden menu and do it again. How can you get it to stay permanently?

if you need any help; please pm me, or search this site for answers. I am sure you are not the first person, to want to do this or to have this question.

To undo any and all of the changes that you are about to make to your phone(**NOTE** the following will erase all data on your phone so backup everything you want to keep.), (1) first download an app called MSL utility and write down your MSL code on a computer, or any other device maybe even pen and paper.(2) go to your phone settings hit activate this device when it is done loading do not click done.(3) click on the menu button and go to PST settings. (4) go to the ##SCRTN# menu and follow what it prompts you to do, your phone will then reboot automatically. (5) do steps 2 and 3 over again and go to the ##RTN# menu and follow the prompts your phone should than reboot automatically and now you should see an invalid SIM sign. **NOTE** any time it asks you to enter a code it means enter you MSL code. Remember to undo these steps first. (No. 2)**NOTE** when your done with steps below download BuildProp Editor(you must have root), and click on the pencil icon; scroll to the bottom, and add these two lines: ril.sales_code=LOL ro.csc.sales_code=LOL)
No. 1) = No, you do not need to downgrade.

done.
This is a re-post(i would thank whom ever posted this, though i do not recall where i found it.); because i am to lazy, to write it from scratch.
1. Use ssu.apk to unlock it first
2. use cf auto root to it
3 .use adb:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
UMTS -> DEBUG SCREEN -> PHONE CONTROL -> NETWORK CONTROL -> GCF
There the phone is domestic unlock without downgrading the modem.
1. be on stock NG2. ssu.apk force-closes on aosp/custom roms.
2. Run ssu.apk and do the unlock. This does not require root.
3. do the other commands through ADB(step 3 Above), just in case. You may or may not need them. I don't know why it worked for me without them. That step DOES require root.
4. Test your sim card and make sure your phone can read it, and if possible, make a call, try text/data, whatever.
You're Welcome!

I had NAE i downgrade to mdc then unlocked it and after that i download firmware which is NG2-xas i think and after upgrading its still unlock.
For that method and files you can search international sim unlock.
Its easy to do it.

Thanks so much for the quick response!
Couple of things, I actually called Sprint to ask them to unlock it for international SIMs, and they said they'd go ahead and do it. I flashed back to Stock and did the UICC Unlock thing in the menu like they told me. The phone rebooted. I think it's unlocked then, correct? If not, I'll go ahead and do this method tonight.
Also, does this phone support LTE (Is that the right term) on international GSM networks or just 3g?
Thanks!

it may be unlocked; you would not know for certain unless, you attempt to insert an international sim card.
Depending on which country you are traveling to. Some countries only have 2-G, then there is some that use 3-G, some also utilize HAPA+, and LTE. It also depends on the sim card they give to you. If the give an LTE sim card, it may work (for LTE or HSPA+). Though it depends on which band/frequency, its relying on. click here to see LTE frequency data sheet. click here to select the country you are traveling to, this way you'll know if you will be able to be on a favorable network.

2. Choose this APN and back out to your home screen
3. Install Phone Info (Samsung) or dial the secrete code to open GCF settings on the phone (*#4238378#)

4. Tap on GSM/(E)GPRS/WCDMA GCF ON

This should solve the issue. If this helps you out, please pass the favor and help others.

[GUIDE] HTC Desire 626s Sprint - Sim Unlocking for GSM / LTE Band Unlocking

[GUIDE] HTC Desire 626s Sprint - Sim Unlocking for GSM / LTE Band Unlocking
I successfully sim unlocked | unlocked LTE/GSM bands on the HTC Desire 626s Sprint variant using info from guides by @be free and @dr.faramroze. A big thanks to these fellas! You won't know it is unlocked until you put an active GSM Sim Card in. When trying a non active GSM sim it doesn't register correctly. I am unsure of why this occurs right now. When i get more time for this handset I will figure it out. I would recommend flashing the Unbranded MM 6.0 Stock Debloated Rom before doing these steps. It's much better and lacks all the extra garbage not needed. If you want to here is the download link - https://drive.google.com/file/d/1ZaQMcUMoGoKuZ781AJIKOrjubpx6frpK/view?usp=sharing
SIM UNLOCK WORKS ON: Sprint - HTC M9 / HTC Desire 626s / ??
LTE BANDS ON: Sprint - HTC Desire 626s / HTC A9 / Samsung Galaxy S5
Required>
1. Drivers
2. Applications I Uploaded/Linked
3. MSL/SPC
4. Phone with S-On / S-Off + SuperCID = better
5. Patience
Instructions:
1a. Start by downloading all of the files attached to this thread. If they do not download you can download them from [https://www.androidfilehost.com/?fid=11410963190603843197] alternatively.

3a. Run the application named "Basic-Flasher" that you downloaded in step 1a. If it fails to launch this is because you don't have the required run times installed. Goto microsoft.com and download the latest packages. If it still errors just click "continue" and then click scan, select your port # then click connect. Next to Method in the drop down box select [HTC]. Now click Read SPC and your MSL/SPC should appear. Copy this to notepad, piece of paper etc.
4a. Dial ##3424# in your dialer and input your MSL/SPC you got in step 3. Now Choose [DM ON] and activate it. IF it is already activated simply deactivate then reactivate it.

Try your active GSM SimCard now. I'm testing with ATT getting HSPA+ and loving my horrible 3G data speeds! But hey what can you expect. =]
Now to enable LTE Bands if you must (Not everyone will be supported). This mod enables obtaining LTE - bands 2,3,5,13,17,25,26 after making changes to NV Item values. Band 5 is reported to be excellent with great coverage. Making these changes will not damage your Modem / IMEI / Hardware.
Steps:
(To be continued)
