Hidden Codes? - Verizon Samsung Galaxy S7 Edge Questions & Answers

Does anyone know how to access the Special Menus and hidden codes for this device on either the U Firmware/Software build or Stock. I am asking because I am trying to access the SimToolKit and certain engineering/Debug menus.

Developer codes

I'm referring to those #74*67885*1# type codes that show system parameters and perform special functions.
Where would I find them, and what are they called?

Verizon Galaxy Note 3 - Accessing Hidden Menus

I had run into this issue previously and thought this might help those who are looking to punch in these codes and check out the hidden menus.
First off, I am on a Verizon Note 3 and I'm rooted.
By default, Verizon does not enable the hidden menus. In order to enable them, you'll have to use Root Explorer or Root Browser in ROM Toolbox and navigate to /efs/carrier. Then you'll want to edit the HiddenMenu file so that it says ON instead of OFF. Make sure you use capital letters.
After that, reboot, and you should be able to start punching in codes from your dialer.
Here's a link to more codes that may work for your handset: http://rumorscity.com/2013/09/26/samsung-galaxy-note-3-secret-codes/
On a side note, anyone ever use the Self Test hidden menu and try the Melody/Speaker test? What song is that...?

Note 4 AT&T No Preferred Network Mode in Settings

Hi Guys,
i have a problem with my Note 4. I attached a screenshot and you can see that there is no Preferred Network Mode option in it. I also try the code (*#*#4636#*#*) for hidden menu to change it but nothing happens coz when i changed the setting from GSM/LTE/Auto to GSM/CDMA/LTE/Auto and go back from the menu it will be revert automatically.
Can someone fixed it or have any solution???
Is there any one to help ????
I believe it requires a build prop or csc code edit that requires root for the settings menu but the service menu method should work as long as you do it correctly...and I say correctly not assuming your doing it wrong but to encinuate that there is a certain way you have to enter the keys..... Google it and you should be able to find a video

[GUIDE] unlock APN settings on stock firmware

if you have a problematic firmware that won't allow you to edit your APN settings in the dialer hidden menu, this may be what you need.
first, the warnings:
1. THIS IS ONLY FOR SPRINT SAMSUNG PHONES RUNNING TOUCHWIZ ROMS!!! never attempt on any other carrier or manufacturer's device or alternate roms! it should most likely work on other Samsung Sprint devices with stock/touchwiz roms.
2. DEPENDING ON DEVICE, YOU ARE MOST LIKELY TO BE FORCED TO FACTORY RESET YOUR DEVICE IN THE PROCESS, which likely includes LOSS OF ALL DATA ON INTERNAL SD!! take all necessary precautions.
3. ROOT REQUIRED
4. you will STILL NEED your MSL number!!!
5. have a FULL backup in TWRP ready in case anything goes wrong. INCLUDE your EFS in the backup!!! again, INCLUDE YOUR EFS. make sure it's stored on EXTERNAL sd card. again, EXTERNAL SD CARD!!! or copy it to your PC if you don't have an external card.
here's the short but sweet guide.
1. download "Samsung Phone Info" from Google Play
2. swipe over to the CSC section.
here you should see:
Firmware's CSC Code
Active CSC Code
Available CSC Code
3. if Firmware's AND Active both say XAS, you should already be able to edit your APNs using your MSL number.
if Firmware and Active codes do not match, you have a dirty rom and I am unable to help you correct it, you'd best try a different stock based rom or 3rd party that allows it by default.
if Available CSC Codes does NOT include "XAS" then whoever modified the customized stock touchwiz rom you're using removed it and you'd best try a different stock based rom or 3rd party that allows it by default.
4. using any CSC editor, change "SPR" in ALL places it appears as only the 3 letters "SPR" to XAS
5. confirm changes and reboot. you will now most likely lose ALL personal data on your phone and should now be able to edit your APN using your MSL inside the dialer's hidden menu.

Have you found a way to retrieve your MSL without calling sprint? I've tried all the tool apps in the play store and using a logcat within the ##3282# menu with no luck. Getprop ril.MSL yields nothing, not even a not found error.
I've tried calling sprint for my MSL but refuse to release it.. I'm not exactly on their "nice" list - they've even called to tell me I'm "using too much of my [UNLIMITED] data" many times so I don't expect much from them anymore..
Any help or direction would be greatly appreciated
try the Sprint chat -- through the website, NOT Facebook, and have a good reason ready as to why you need the MSL, other than for bypassing their security lol
Holy **** after searching high and low I have FINALLy found a way to get back editing my APNS for hotspot on my rooted Sprint Note 5! AND I keep Android Pay! Thanks so much!!
This works perfectly! Only thing is turn on hotspot option disappeared from settings. I can turn it on and off from the top bar if I swipe down. OR I can download a hotspot shortcut app and access it from that app.
Also I noticed my icons for LTE now say 4G and the bars are different too - more old school.
I noticed I changed EVERY SPR to XAS - do ALL of them NEED to be changed to enable APN editing? Can I switch back the ones that give me back hotspot option in settings and stock LTE & bars icons?

this **might** be fixed by renaming (or deleting, if you're brave) the features.xml file, if I remember correctly, stored in system/csc/ or system/etc/ not sure honestly
features.xml.backup should do just fine.
if the rom doesn't boot afterwards or if the dragons catch all your apps on fire, go back to recovery and use TWRP's file manager to change it back
also, any xposed app (like wanam's) or other feature.xml adjusting apps (like GalaxyTools or Samsung Phone Info) can cause the problem to happen again.
the alternative / temporary / dirty-fix would be to create a shortcut to hotspot on your home screen:
1. download Activity Launcher from Google Play
2. launch and change recent activities to all activities
3. wait approximately 72 years for it to load
4. scroll to Settings and tap it
5. scroll to Hotspot and long-press it
6. tap create shortcut
7. never uninstall Activity Launcher -- instead just make it a hidden app (it's very small anyways)
I can just longpress hotspot toggle in slide down drawer from top no probz. Which CSC settings modifies the ability to edit APN? I want to put the rest back to SPR.

I used the msl code and everything appears the way you say it should... but the phone STILL says invalid sim!
What internal file must be deleted, the thing is unlocked on sprints end it just wont let go !

Hello,
I rooted Sprint Note 5 from Nougat to Magisk and went ahead to replace SPR into XAS in all files under system/CSC folder. APN Type is still coming greyed out. Any help will be appreciated.

LTE features / G950U rooted

Hi guys,
I have rooted G950U1. Anybody knows how to turn 4x4 MIMO and 256QAM on in this mobile phone? In the past, there was tutorial how to do it (secret menu *#2683662#). But it was working only on first 2-3 firmwares. Since the root on S8 works only on the latest version of Android 7.0, this option is not available.
Any ideas on how to do it?

Do the dialer codes work on 950u1? I may be wrong but I think most of the dialers work on carrier firmware except Verizon. Again I may be wrong.
If your rooted use shortcut master and you can search for it
You have to use app for that. I'm using Shortcut Mater (Lite). I found very similar secret menu. But there is missing few options which were in old menu. I was able to turn on 4x4 MIMO and will have to test it. Very interesting was CA combination menu. There were 3 options and only in 4CA Combination was written some combination. In 2CA and 3CA were missing those combinations. I'm trying to find why is CA not working on my phone.

Unfortunately starting with Android v8.x.x (Oreo), all test commands sent to the RilServiceModeApp via android_secret_code://2263 even by root are denied.
Without root, the only way to enable the band selection menu (keypad codes *#2263# or through the eng-menu *#27663368378# used to set bands and CA's), is via combination firmware or a test cable (which at this time is not yet available for USB-C, only for micro-USB).
You can also try inserting different carrier SIM cards which will reboot and reconfigure the phone on a blue screen, and if you're lucky a particular carrier's CSC will allow you to access the hidden menus via keypad codes.
If you have root, you can try the following:
1. On combination firmware edit the file /efs/carrier/HiddenMenu and /efs/FactoryApp/keystr to be "ON", which will persists even after flashing back to stock firmware.
2. Copy the <CSC>_keystrings.dat from system/etc to root/etc and set permissions to 0744.
3. You can try replacing the /system/priv-app/ModemServiceMode/ModemServiceMode.apk=com.sec.android.RilServiceModeApp from a previous Android version when it was still working, and set the permissions to 0744.
The following is only for phones with a micro-USB port, nonetheless it makes an interesting way to enable the hidden diag menus.
Without root or having to flash it with any other CSC firmware, you can actually enable most diag codes (including RIL test codes like *#2263# band change, *#2683662 lab test mode, *#2766338378# engineering diag menu, etc) on pretty much any model/firmware/region by simply plugging in a test cable into the phone (the other end doesn't have to be plugged in anywhere, it's just the built in resistor which enables diag mode/FactoryMode).
It's important to follow the next steps exactly in this order: Open the dialer, exit the dialer with the Back key (not the Home button!), reopen the dialer and now it should accept most test codes.
These cheap test cables can be found on Ebay or AliExpress, just search for "Samsung 523K uart cable" or "Samsung 619K uart cable". Some come as a combo where you can simply switch the resistor values via a switch, but you must try both values, since only one or the other will work on certain models/firmwares/regions.
I've been using this method successfully for many years (currently on my Samsung S7 with the latest 2019 firmware), unfortunately these test cables are only available for micro-USB connectors, so it won't work on the newer USB-C phones even with an adapter (because it doesn't extend the resistor lines, only the data lines). If anyone finds a solution for USB-C, please post a message here.
