[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I have never used AT&T mobile, but everything I've read indicates that they are very "rigid" about what they will allow on their network. I also believe their tech support is giving you bad advice (for example, even if their network ceases to support 3G, there isn't a need to set the bands to LTE only, as the phone simply won't/can't connect to 3G). Further, they are likely getting their information about your phone from the IMEI number, which won't change as you try different solutions.

See https://xdaforums.com/t/us-users-op...s-on-t-mobile-in-the-us.4311583/post-85423413 Be sure to use the IMS Settings app (the Play Store listing explains how to configure it). The phone must be rooted (Magisk). If the VoLTE icon appears 10 seconds or so after you configure IMS Settings, then you have VoLTE (notwithstanding what AT&T says).

T-Mo will tell you a particular phone works or doesn't work on their network, but they don't block phones AFAIK; AT&T may block. If they block you, it won't help that the phone actually works. You can always switch to T-Mo (or a T-Mo MVNO). The SM-S930F works fine on T-Mo/Mint *IF* VoLTE is enabled.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
That is correct, they are using the IMEI.

I installed "IMS Settings launcher Samsung (Enable VoLTE)" by JunHyung Lee from the store. I granted root permissions, and it gave me the error, "Not found any CSC features for IMS."

The problem with EVR is that this phone is a W8 model, not a F model, so EVR would not flash in Odin. If you know a way to force it to flash, I'm willing to try, because the hardware is identical, but whenever I try flashing stock 930F images, it always fails with a one of several error messages showing on the download mode screen.

EDIT: Is it possible to only flash the CSC portion of the EVR firmware to my phone?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
When I attempt to flash HOME_CSC_EVR...., I get the error, "SYSTEM REV. Invalid magic string."
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I'm sorry; I don't know anything about the W8 version of the S7. If it uses the Exynos processor, you have hope; if it uses the Snapdragon, you don't.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
It is the Exynos platform, just somehow numbered differently.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
DevBase allows you to reflash the ROM with a different CSC. EVR is not included in DevBase, so I tried BTU. I now have a setting for VoLTE calls in my Mobile Networks settings! Unfortunately, I still can't make calls if I change to LTE only mode. Makes me wonder (again) if AT&T is simply blocking my phone because it isn't on their privileged list, or if the Exynos platform simply doesn't support AT&T's particular implementation of VoLTE. Their tech support people have been super unhelpful in figuring that out. If I wasn't an OTR trucker by trade, I'd consider switching to T-Mobile.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I don't use "LTE only" mode. VoLTE works great (T-Mo).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
Wish I could say the same. This is on standby:

This is during a call:
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I can see from your images that VoLTE is NOT enabled, as there is no VoLTE icon (it should be to the immediate left of the 4G icon). Did you try the IMS Settings after you (finally) got the ROM installed?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
The phone itself seems to have VoLTE available:

I'm not sure what to do with IMS Settings. I chose the ATT VoLTE profile and "Manual Register", but nothing changed.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
It is my understanding that no icon, no VoLTE. The author's narrative in the Play Store gives the necessary settings.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
Yeah, agreed that I don't have VoLTE. I just don't know why. I suspect the AT&T is blocking access to VoLTE to any phone not on their whitelist.

I found this post about VoLTE on Samsung in Romania:

https://volteromania.blogspot.com/p/samsung-voltevowifi-settings.html

It led me to the customer.xml file I found in /system/csc/[CSC_CODE]/system/csc/. [CSC_CODE] is BTU in my case. Since BTU is a multi-CSC, it contained "NetworkInfo" entries for a large variety of carriers in the UK. Seems like if I could get my hands on a legit AT&T CSC customer.xml file from a US model S7, I might be able to add an entry for "ATT" with its settings, or create an "ATT" CSC outright for this device, and reflash. But I'm not sure if I know enough to pull off something like that! Also, if AT&T is blocking my device on their side, it won't matter what's in my CSC file.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
@_alexndr: I have extracted CSC_ATT from the G930A firmware found here, and I've extracted your ROM .zip file, but I'm not sure what to do next. How would I go about adding the ATT CSC to your ROM so I can test it? Is this even possible, since the G930A is a different hardware platform?

Edit1: you can find the zipped sec_csc file I extracted from cache.img.ext4 here: https://drive.google.com/file/d/1Bo8katIE1c5hR6Mk9D2uj7Z7dEeN-YzA/view?usp=sharing

Edit2: is it possible to simply create a flashable zip with the ATT CSC, rather than altering the whole ROM? I don't know how to do that, but I could learn.

Hi. First time user. I was using EvolutionX 5.9 for about 3 months now. But i wanted something closer to stock so i downloaded and tried to flash this rom. But when flashing it i get an error that says "This device is not G930F"😔. I tried everything. Clean wipe, full system wipe,and even data wipe but nothing. 😔Even changed from TWRP to Orangefox recovery but did not. Eventually i got tired and changed to FloydQ instead.😶 If anyone knows how to solve this error, it would be of great help.😀.

Just for the record, i do have the Exynos Galaxy S7. Korean variant.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Feenix0:
You need to use the "skipvc" option.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] PK 2077:
Please tell me how to do that? Coz when i just try to install it, it doesnt work.I just tap install in twrp and i see error that says "this rom was designed for sm-g930f" and aborts the installation.🙂

As with all the options, you add it to the filename.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] PK 2077:
I have one last Stupid question to ask.

Does this rom actually support SM-G930L?

Again it is a stupid question but please do tell.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] nospamboz:
It works! Got T-Mobile USA (TMB) VoLTE and WFC (IMS) working on my G930F. @_alexndr, I sent you a 15 euro thank you for letting me keep my phone.

I got a SMS from T-Mobile earlier this week saying I needed to switch to LTE from 3G. Though I had last heard that TMB wouldn't be switching off 3G until 2022, new information showed up on some websites recently saying that they were now doing so on October 1, in just a few weeks! Fortunately I had been looking into it for some time, and had a probable path: the @_alexndr ROM plus the @TEKHD IMS TMB enabler. (That enabler was mentioned on a G935F post, here: https://xdaforums.com/t/rom-g935f-f...cryption-support-jul-10.3591647/post-81838913)

My method started with removing my SIM, then both Titanium and TWRP/nandroid backups to an external SD card, supplemented with TWRP File Manager "Copy Folder" onto external SD for both /data/media and /efs. The ROM install went fine, but I fell prey to the did-not-enable-OEM-unlocking-in-Developer-Options FRP trap, which necessitated downloading a pure BTU stock ROM from Sammobile and installing with Odin, then disabling FRP by adding and deleting my Google account, then doing a factory reset on the stock recovery. All that finally enabled me to install TWRP again with Odin, reinstalling the @alexndr ROM, and finally enabling OEM unlocking. Whew!

After re-installing my SIM, I initially couldn't use IMS, which showed in the phone setting status as "unregistered". But then I TWRP-installed the IMS TMB enabler, and when I rebooted, there was the WiFi Calling notification! Woohoo!

I also have an ATT SIM, so I'll let you know later if I can get that to work. I'm all hacked out for the day.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
Congrats ! What was your starting CSC (BTU ?), and your final CSC ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] nospamboz:
I was originally on LineageOS 14.1, which doesn't support IMS (it being Samsung proprietary), and so doesn't have a CSC, not even under /system. I didn't check, but I assume the @_alexndr ROM sets the CSC to BTU by default, especially after the FRP BTU episode. Now with the @TEKHD SMB enabler, I've got several CSC "answers". The "*#9999#" dial code (the only one that works) says "CSC: G9555FOYN1AQ9". "/efs/imei/mps_code.dat" is "TMB". "/system/omc/sales_code.dat" is "XAA", and "/system/omc/code" is "OYN".

When I get around to trying ATT, I'll look into this again.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dantexperia:
Hello, I want to test this rom on my G930F, but I have a question, my way to install a rom is as follows:

1- Clean installation of Germany firmware version G930FXXU8ETI2.

2- I configure, developer options, oem unlocking, usb debugging, shutdown.

3- Using Odin I install TWRP (previously I copy the rom on the micro SD), once in TWRP I format data, all the wipes and proceed to install.

4- Again wipes, I install magisk from TWRP and I start with the new rom.

I always did these steps and I never had problems, but my question is if I have to root the firmware before installing TWRP and then proceed from step 3.

I hope they remove that doubt from me, thank you very much in advance, greetings.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I have used this ROM for several years, and suffered from repeated random reboots. As an experiment, I switched to the ThundeRStormS kernel and I haven't had even one random reboot since.

See https://xdaforums.com/t/rom-g930f-f...cryption-support-jul-10.3592914/post-84051449
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Droiderat:
I'm using ThundeRStormS-Kernel-G93X-TW-OREO-v4.5-20210721.zip. As I recall, when I switched from the stock kernel, it didn't recognized the credentials of my previous WiFi access points. However, once I reentered the credentials (1 by 1), WiFi works fine. In fact, since I live in a dense urban area, I'm on WiFi much more than I'm on 4G. I never have any problems with it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] xxxmadraxxx:
I've just installed this ROM yesterday and so far, so good. Just one minor issue though. My lockscreen piccie is pretty light and I used to have my clock text colour set to be red as the default white text was unreadable. This is [or was] available under

Lock screen and security > Clock and facewidgets > Clock style

However tapping on Clock style in this ROM does nothing. It just highlights with the tap but the setting doesn't open. Anyone else seeing this?

And, while on the subject; does anyone know where I'd find the preference file for this in the filesystem, so I can try and edit the clock colour manually?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pointgourd:
But I need root so can I install root by flashing magisk after setting up everything?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] hell1134:
Oh ... I do not need root so I did not flash magisk. I guess you will have to test it yourself.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pointgourd:
And sorry for bothering but do you happen to know which CSC should I choose for most of the CSC mods? Thanks anyways.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] hell1134:
I let the ROM decide what CSC to use. It automatically selected the correct CSC based on my SIM.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pointgourd:
Do you have call recording and other csc features? Because whenever I flashed this rom I had almost no features available.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] quahog_ca:
Just wanted to say a quick thanks for this wonderful ROM. I've tried many others but ended up here because I still use my S7 as a daily driver and need device encryption and good camera support (optical image stabilization) and this seems to be the only ROM to support both.

BlackDiamond and FloydQ, although nice, do not have device encryption.

PixelExperience is also nice, Android 12, but lacks OIS for the camera so takes blurry photos in low light.

Again, thanks!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] xxxmadraxxx:
Well, it looks like I'm the only one with this problem. Shame really as, otherwise this ROM has been rock solid for me. But, with no way to access the clock style settings to change the font colour, it's just too annoying to have to unlock my phone every time I want to take a quick glance at the time.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] xxxmadraxxx:
Just in the unlikely event anyone else runs into the same obscure problem I had:

I've solved the mystery. It turns out that having 'Always On Display' frozen [in Titanium Backup] also renders the 'Clock Style' setting button inoperative. I had frozen it as I never use AOD.

I 'defrosted' 'Always On Display' and the Clock Style button is now working again. So, apologies for my mistaken belief that this excellent ROM was at fault.

Hi Alex

Have been using your Rom (G930FXXU8ETI2_DevBase_v7.3) for some time now and thankfully have had no issues what so ever :) so many thanks for that really nice job. I'm a noob and could do with some advise I just wanted to ask what is best way to update my rom to your new one (g930fxxu8eue1_devbase_v7.4.zip) I'm currently using Magisks v22.1 and safetynet reports failing but I have just tried a new app Yasnac which checks safetynet status and that reports a PASS on integrity and CTS profile so not sure what's going on there maybe due to magisks not supporting Hide any more so probably why it reports fail and don't want to update Magisk in case just safetynet fails just thought I would tell you state of my device! in case. my banking app also works so it looks as though Yasnac is reporting correctly!. but any way I also have TWRP installed as well obviously so because my galaxy S7 is rooted using Magisk do I need to disable magisk and if so what is my next move! do I need to uninstall old rom first.

any guidance here would be really appreciated like what order to do things in!.

Many thanks

regards CS

Hello, would you please give me an advice ... Last year I flashed Alexndr's latest ROM on my mobile and it worked fine till 1-2 weeks ago. Then the screen started to freeze, the touch didn't react/reacted severely delayed. I could't remember any updates during that time.

So I decided to flash a stockrom from Sammobile for the S7 with Odin ... it failed (Odin), the mobile got stuck in download mode. I tried it once again - failed again. Now it shows a blue screen "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". This doesn't help either, my device is not recognized. I read in other threads that flashing stock over Alexndrs' is possible. Was I wrong? Is there a way to rescue the S7?

Hi

I had your first rom installed G930FXXU8ETI2_DevBase_v7.3 and started getting really bad download speeds had it installed fore a while but don't know when issue started just seemed to get worse over time! so I have just updated to v7.4 and there is no change still getting really bad speed 4mb. I have checked sim on another phone and its not network issue also rang the Three network they couldn't find any issues.

i just wondered if you know of any issue with network speed problems with this rom.

any help here would really be appreciated.

many thanks.

update;

Think I found the issue!. seems it selected 3g/2g (auto connect) in Networks. Not knowing what (LTE Only) was didn't think of choosing that one till now :/ so although there's an auto connect for all three I ended up choosing LTE Only didn't think much point in flipping between them as there old services. now I'm getting mad speeds, guess I should have checked LTE meaning, though its hard serching for solutions when you don't know much about phone roms and rooting. you live and learn.

after trying for a while found that selecting just LTE is great for net but can't ring anyone when dialing phone just disconects the second you select contact to ring!! so selected LTE/3G/2G (autoconnect) and can now ring out but net is back to crappy yet again. this crap is getting on my last nerve. thinking about buying apple had enough of googles crap and looks like ther is no desent roms around all seem to have some issue or other.
