I have an International SM-G920F but I can't open SERVICE MODE like I did with S4, Note 4, S5...
(dial *#0011*, menu->back, menu->insert key, type Q0000 and press enter)
And other codes found online don't work.
Does anyone know how to open SERVICE MODE ?
I need it for BAND SELECTION and other stuff...
Thank you for Help
AOCV fw was the last one that I could open the service menu, since then it never opened. I wonder if it's disabled by Samsung in new updates?

I'm wondering if this is the case, since I was able to access it yesterday, but not today. I just received the latest update this morning.
So what happens if, say, someone set their phone to a certain LTE band and they not want to restore that setting to "automatic"?
Look here on you tube

This is not service mode...
With service mode you can make band selection, advanced network setup, etc
Anyone?
Band selection is *#2263#
But I can't get out to any of the other settings

I can't access this one either. None seem to work for me.
Its based on your firmware CSC probably... Some regions have it and some don't.
Out of the latest versions of FW (AODG & AOE3/4) I've tried: France, United Arab Emirates, Vietnam, Thailand & Slovenia. None of them allow you to access any service mode menus. Using old FW like AOCV and the service menu works.
Can anyone at all confirm service menu working on AOE3 or AOE4? Try *#0011# in your dialer.

Do you know which file/directory are changed by Service Mode BAND SELECTION?
Because we could go back with OCV firmware, do BAND SELECTION (in example LTE/WCDMA ONLY) and see what files/strings are changed, and then manually change files with latest firmware.

Was your phone originally a UK model?
Nope it's originally from Vodafone Germany and the service menu worked on the original rom too.
Hello, I'm working to fix and restore Service Mode and Band Selection.
I need somebody with SM-G920F and FULL WORKING SERVICE MODE (I mean not only *#0011#, but also BAND SELECTION).
That person, must root his own phone, and send me these files:
- /system/csc/customer.xml
- /system/csc/others.xml
- /system/build.prop
You can send me an email at [email protected].
Let me know ASAP, Thank you all !!!

You may have to activate with the att sim that came with the phone first. Just activate it as a go phone for free so it registers in their system

Hi All,
I have bought sprint s8 plus and unlocked it by using one of the unlock service provider from ebay to be used in India with Airtel network. But now, I am getting the below issues:
1) If I selected the Network Mode as (LTE/3G/2G) (autoconnect) then I am not able to make and receive calls but internet(LTE) is working fine if I enable the Mobile Data.
2) If Network Mode is 3G/2G (autoconnect) or 3G only then I am not able to register to the network (Airtel).
3) In 2G only mode, I am able to make and receive calls and data service is Edge only.
As per the Phone Info app:
Firmware's CSC code: XAA
Active CSC code: XAA
Available CSC Codes: ACG, AIO, ATT, BST, GCF, LRA, SPR, TFN, TMB, TMK, USC,VMU, VZW, XAA, XAS
Bootloader version: G955U1UES5CRL2
CSC Version: G955U1OYM5CRL2
Baseband Version: G955U1UES5CRL2
Is this possible to fix the above issues by flashing the different firmware and change the CSC codes etc?
Thank You.

Do you mean the option in the menu is missing? Check your quick pull down menu to confirm this, is there an icon in that menu?
What icon appears next to your signal strength? Does it say Vo))?

Well it means your phone has not been updated correctly. Oreo for S7 stock has wi fi calling switched on automatically if your network supports it.
You can download the stock firmware yourself then flash via Odin to fix the issue but please check you are looking in the right settings first.

Ok yes, i can see Wi Fi calling (which is the last option) is missing. If the option is missing it means the firmware you have does not support it. So like i said i would flash unbranded firmware so all options are available.

If i do so, is my warranty will be void? I mean if i flash the Official Rom for my country using Odin my phone will still be in the warranty?

No, flashing stock firmware via Odin does not require Root so warranty will still be valid. Also download and install Samsung Smart Switch to check there is an update to the current firmware on your phone.

I wanted to ask what's all this files does and if i put the Bootloader file is it will void my warranty and can you explain me all the files matters?
Thanks.

Hi there,
Cutting to the chase.
Australian, use Vodafone AU when at home, but working in the Philippines a lot this year (Smart Philippines), plus travel often to Taiwan.
Need VoLTE for VF AU, would love it for Taiwan (TW Mobile), dont think Smart offers it at all in PH YET, but if and when, would also be great, but less critical.
Currently have a Pixel 3 XL from VF AU, so thats sorted.
Wondering, if I get a Oneplus 7 P, what is likely to be needed to make it work?
Previously had to run custom ROMS on previous HTCs to get non native network support for VoLTE, even then it required the ROM cooker to code it in.
Please educate me!
There was a way to force enable Volte on my OP6
I'm pretty sure the process would be the same
I'll link it when I get behind my pc

that should be enough to get it working *#800# used to enable the switch, they probably changed it.

there must be a way to enable serial and full-port switch (also the VOLTE switch similar to *#800#)
im pretty sure its a qualcomm / factory mode settings, it must have moved somewhere else.
i cant image oneplus getting rid of it all together.
whats TP debug?
ive sent an email to OP hopefully they can get back with an answer.
i know my pixel3xl enters a qualcom mode when i press the volume up button and have it plugged to my PC (from power off - hold down volume up and plug into PC)
maybe its similar?

you could wait for the MSM tool to be released
if you break something you can always use the MSM tool to repair EFS
pretty sure you can create a backup of efs using fastboot (i dont know exactly how)
I have VOLTE just popped sim card in and it showed up. Didn't have to do anything. 12gb unlocked version on ATT.
Qualcomm drivers don't seem to work with the 7. Can't find the device in PDC after enabling serial & full-port switch.
I noticed compared to the 6, that VoLTE and VoWiFi works for one of my carrier (Vodafone NL) out of the box. The trick that I did on my 6 also made VoLTE work for my other carrier (KPN NL) which doesn't work with the 7 pro out of the box.

Out of curiosity, what was your phone before? Mine is due for delivery today, I have ATT and my phone before is a 6T. Just wondering because I want to make sure I still have VoLTE. Thanks!

did you open as admin? i dont see why it wouldnt work
did you connect phone then open the PDC software?
perhaps we need an updated PDC/QPST tool?
Qualcomm drivers: https://qc2.androidfilehost.com/dl/...4074/QUD.WIN.1.1+Installer-10037.3+Setup.zip?
QPST: https://qpsttool.com/qpst-tool-v2-7-474
try these. they look like the latest versions.
perhaps try a different USB port also.
if this doesnt work, we might have to try and get in touch with the OP and see if they know of any way to get it working.
i dont have my 7Pro yet to try this.
I tried with 2 different computers and I have those exact versions you linked installed.
Yes, I opened as admin.
Yes, I connected the phone first then opened the software. I tried reconnecting with the software open too but also, no luck.
I tried searching for a driver in Device Manager manually by browsing to both the Qualcomm and OnePlus folders.
