Trying to launch service mode to change some LTE carrier aggregation settings (Exynos on T-Mobile, need to change some stuff to make it better).
Obviously you can't without root, so I use the Phone Info app which has a root enabled service menu launcher, however when I launch any menu that needs root, I get this error: https://imgur.com/a/lwMeTxr
I've tried a lot different apps and even terminal methods to launch this menu, all of them give the same error. I've confirmed this works fine in Oreo on my old S8 and S7 but it's doing this on my S9+.
I'm running Soldiers ROM BRJ3 with the T-Mobile detonator CSC v4.1, everything else stock. G965FD.

I decided to root my Galaxy S7 Sprint running Nougat (SM-G930P) The process went well, successful root and all. I fixed mobile data too, but SMS and phone calls aren't working. I looked at all the guides, telling me to put *#*#4636#*#* in the dialer, and change the SMSC, but it won't bring up the 'menu' So I am kind of stuck, any alternate solutions?
N920A AT&T (Required VoLTE or Root or Unlock Bootloader or Any Better Alternative)
Dear's
I have Samsung Galaxy Note 5 SM-N920A with Andriod nougat 7.0 (which U.S with AT&T). So basically i'm back to india. Now i want to use jio network sim card which only supports VoLTE.
I will post my questions in order, because since days i have been doing research and found nothing helpful.
1. I'm trying to use Jio network, which requires VoLTE, any patch or fix available?
2. Since i couldn't find patch tried another variant Rom which brings me to a problem of Bootloader by AT&T. Any way to unlock bootloader?
3. Now since i cannot find unlock bootloader i tried to go for root. Here goes with more issue there is no root. (Available if downgrade but would be stuck on some 5.1.1 also no way of downgrading). Any way to root?
4. Since no root i tried with many setting change at APN, *#*#4346#*#* (VoLTE wont get enabled), and so on. Nothing VoLTE shows up in settings. Any better option?
5. Wanted call recording since Jio 4G app is VoIP based call recording apps wont work with that. Any better suggestion if using Jio 4G Calling app with recording?
I want to try and enable VoLTE and wifi calling on Three uk on a J8110 as the signal is marginal in the two locations I'd like to use the phone from and coming from a samsung S7, I can see that the phones a few db's down on signal to start off with, so I really need the VoLTE or wifi to make the phone useful to me.
Now under this thread:
https://forum.xda-developers.com/xperia-1/help/google-dialer-volte-t3975441
They say they managed to get VoLTE going using root.
1. Root
2. File Manager with root support
3. Go to /oem/modem-config
4. Delete "anysim" folder
5. Rename "S9033.1" to "anysim"
6. Go here " https://forum.xda-developers.com/showpost.php?p=80231731&postcount=395" and download "VoEnabler.zip" From the Google Drive link
7. Put "VoEnabler.zip" onto your device and install via Magisk and reboot.
8. You should now be able to use VoLTE and VoWiFi.

So my three questions are;
Is this likely to work? e.g allow VoLTE and maybe wifi calling
Will it break safetynet by rooting the phone? (as I use internet banking)
Will it break anything else like DRM keys.
I see there appears to be multiple rooting options for Android these days if I can do the above is there a particular rooting method thats more likely to preserve the safetynet compatibility?
And maybe the DRM keys.
As I'm only interested in Enabling VoLTE and maybe wifi calling.
As an aside to that I see in this thread, https://forum.xda-developers.com/xperia-1/help/enable-volte-ee-uk-t3958112/page3
That some people on EE have got VoLTE working without anything special is this just because EE is just a network sl*t and just allow anyone on there system?

If you're on the Customized UK firmware, VoLTE should work by default.
I have the Customized UK firmware downloaded and I just checked, and it does include the required MBN file for VoLTE on H3G in UK. I am on the Dual SIM J9110 however, but I reckon it should be the same on the single SIM J8110 as well.
Yes, rooting will break SafetyNet on the Xperia 1. Magisk Hide works on some banking apps, but some of still fail to work once the bootloader is unlocked.
You will lose DRM keys, but from what I've heard, they are restored if you re-lock the bootloader.

Yeah can confirm its not working on three uk, as other have already said in other threads..
*#*#4636#*#* > Phone info > VoLTE provisioned is grayed out.
Also cannot access three on the 800mhz LTE band 20
TBH three when I spoke to them just wiped there hands of the issue and said we don't sell the phone so speak to sony.
So much for industry standards.

You could try the method that enables the VoLTE toggle. In theory it should work with just that because the required files for IMS registration to work are already included in the modem for the Xperia 1.
why not just flashing another FW before losing DRM keys while rooting
we had a user he used a non European Market Xperia 1
no option for voLTE or Wificalling
after flashing the European FW everything was working just fine for him without any kind of rooting
I have flashed South East Asian (SEA) on mine and it has option for the VoLTE in the Network & internet > Mobile Network
It has Enable VoLTE and it can be toggled on and off. (although we don't have the VoLTE here )
If they are already providing VoLTE. Flash SEA firmware.
Obligatory - This is my first post here, please go easy on me. If this is the wrong section please point me where I need to go.
Okay, I have been having issues getting IMS registration (for att) on my N20U (unbranded) Snapdragon. This is an issue because I don't receive most calls without VoLTE, and the service I am using is actually FirstNet. (An at&t service that provides priority cell tower access for first responders.) Who is also dropping legacy 3G and analogue calling at the end of the year.
The FN sim I was given would not change the network CSC to ATT like it should have in order to work properly.
I was able to get to the manual CSC change menu through the dialer code with a TFW-att sim card (yes, while on oneUI 3.0). I suppose the menu is locked out when other csc's are active.
This allowed me to force change to ATT's csc, then place my FN sim in the phone. The kicker? I had to toggle "do not auto update CSC based on sim data" in the menu to get this method to stick.
Things are grand, working fine, but i got curious as to what options the other csc's had to offer. So i start flipping through the list and end up landing on.....you guessed it..... XAA.
Without thinking about it, i ran it, the phone rebooted, and now im screwed. Flashed the ATT rom with Odin- no change. Factory reset? No change. I messed up BIG.
Finale / TLDR
If you didn't get what just happened there, I used a specific sim card to enable a CSC a menu that uncle sammy does not want you playing with. Proceeded to disable auto CSC changing by SIM, then walked back into a CSC that does not allow me to open said menu. Thus preventing my phone from working fully on ANY NETWORK ever again. With root impossible...
Side notes that failed: Tried fac reset/ tried firmware flash/ tried samkey (no android 11 support)/ tried force change from network side. I hope im not out of options?

Hello,
I have an unlocked Xfinity Mobile device that I bought from Xfinity Mobile. This means that I purchased from them and then paid off the phone in full, allowing it to be unlocked. I can plug in other SIM cards (such as atnt) and have them work fine, which means that my phone is 100% unlocked. However, because Xfinity Mobile is a b*tch, APN settings are still locked for some reason, even when my phone is unlocked. I believe it has to do with the fact that carrier-specific software was installed when I first installed my Xfinity Mobile SIM card. I need to access APN settings to ensure my phone gets full functionality from my new carrier, Visible, which doesn't install any carrier-specific software because it's very new or something like that. Plus, Xfinity Mobile's carrier software doesn't allow me to manually disable 5G functionality (select what bands or whatever I want to use), which I may want to do at some point. I also think the Xfinity Mobile boot load screen is hideous, and I would like to get rid of it.
After searching around, I found out that the best way to do this was to flash U1 software to my phone using Odin with the carrier code XAA or something like that to revert my phone to the original Samsung-bought factory-unlocked state. However, after searching around some more, I found out that to do this, I would have to factory reset my phone and then re-import my apps, data, images, etc., with Smart Switch, which doesn't preserve per-app data. I have way too many apps requiring logins to dig out the passwords for each app and log in again, so I would prefer not to factory reset my phone.
Searching around some more, I found out that it was possible to retain data when switching from U to U1 by selecting the "Home CSC" file instead of the non-"Home CSC" file when flashing with Odin in the respective area where it asks for the CSC file, but this would result in a "Dirty flash" which could brick my phone. Of course, I don't want to brick my phone, so this is kind of a no-go. But, some people did say that using the "Home CSC" wouldn't affect the phone that much, and it was safe to do, but I don't want to put the safety of my shiny phone on the line.
Tl;dr: I want to go from my carrier-locked U firmware to U1 unlocked XAA without losing my data / requiring a restore with Smart Switch. Is this possible?
Both the u and u1 lost the ability to switch lte bands in the June and July updates. The last one that allows changing lte bands is the may update (cvdb etc)

Well, I still want to flash U1. Would flashing U1 Home_CSC bootloop my phone

So then the phone is NOT giving you the popup prompt to reboot to apply new carrier settings, when you insert a different SIM? And it still shows all of the Xfinity bloat and their configuration?

No, if I put in an ATNT SIM, it will switch to ATNT software and install its respective bloat.
However, my current service provider, Visible, does not have its carrier software/firmware. Therefore it would make no sense for me to use Visible on Xfinity Mobile carrier software.

So then can you leave it on AT&T bloat, since that firmware allows APN change/add...?

No.
I'd rather blow my brains out than have 300 useless apps. Also, the actual data indicator icon thing looks ugly as all hell.
Xfinity mobile is more stock than the other bigger providers regarding bloat and other things; it's just that it doesn't allow APN editing, which is incredibly annoying.
