Want to flash custom rom, need VoLTE - Samsung Galaxy S9 Questions & Answers

I'm getting lost in a lot of the information in here.
I'm fed up with lousy performance and charging my phone 2-3 times per day. I've read a few posts online about how the Exynos version is to blame (lucky me, that's the one I have), and that there are some minor tweaks I can do to both improve the performance and battery life.
However, I am dependent on VoLTE and being able to mask root access (actually, I don't really need root access, I just want to change the CPU settings, which I assume requires root access).
From what I've read none of the AOSP ROMs supports VoLTE, and the Lineage crew says it's impossible for them to support it, while other ROMs says that "everything works" which I would think includes VoLTE.
So to the point. I need to keep VoLTE, and I need to be able to mask root. Is it possible to retain those while:
1) Being able to mod CPU settings
2) Being able to uninstall Samsung (cr)apps
3) Getting a clean android experience without any Samsung customization
Device: SM-G960F
Many thanks.

Im on Soliders ROM, very very good ROM.
I have WiFi calling working, but I have to contact my provider and ask for the config file to be OTA sent to me (only if I full wipe on setup)
I have VoLTE, but it doenst work or activate. Not sure its every worked.

Awesome, but now I have a new question. What does bri4 mean? I see BRI1, BRI3 and BRI4 for some ROMs, does that have something to do with which version of the device I have?

BRI4, its just the latest release basically.
Can check in settings>about>software to see your version and work from there

Wifi tethering option not available in hTC One M8

Hello everyone,
I received an hTC m8 (Harman Kardon edition) as a gift. When I received the device, it was factory locked through Sprint Mobile. After a lot of research on internet and on this forum, I have unlocked it to use GSM services in India, and its working fine now.
But now the problem is it does not have the Tethering option. I want to tether my M8's internet connection with other devices but it has no option to enable WiFi tethering or anything. I have also tried a few third party tethering app from play store like(FoxFi, Wifi Tether, etc..) but had no luck. They all failed to start the hotspot and establish a connection.
Screenshot: http://imgur.com/Tl3dxzD
Please help me, how can I enable the tethering or internet sharing option on my device.
Device Specs:
1: Model no: 831C
2: Rooted and Unlocked
3: Android Version - 4.4.2
4: S/w Version - 1.54.654.13
Please help me and let me know if more details are required about my device.

Agree that a custom ROM is likely the easiest way to enable tethering.
Be sure to use one that supports the Sprint version M8.
Also, your firmware needs to be updated before running current ROMs.

Post #2 above already suggested a couple ROMs.
Any ROM that supports the Sprint M8 should have tethering working. I'm not a fan of recommended certain ROMs. I'm not even a Sprint owner for one thing. But more importantly, ROM choice is a matter of personal choice. Its like asking me to pick a favorite color for you.

Thanks for the support redpoint73.
One more question is that you suggested me to flash a "custom ROM that supports the Sprint version M8", though I have an unlocked device, also sprint services are no longer being used as I am using services of Idea telecom in India and I suppose it can support global carriers now.. so is it mandatory to pick the Sprint version only or should I choose a global version.?
I have also read somewhere that sprint charges extra bucks to use its mobile data for tethering services, may be installing a sprint version ROM restricts that tethering option to appear (Just assuming, don't know much about these stuffs).

A custom ROM that supports the Sprint M8 is not the same as a Sprint ROM (such as stock Sprint) or using the phone on the Sprint network.
Its absolutely important to pick a ROM that supports the Sprint M8 (or flash the kernel to get another ROM to work - more on that in the next paragraph). Whether or not the device was SIM unlocked, or even changing the ROM does not change the fact you have a "Sprint M8". There are significant differences between the Sprint and other M8 versions (and being SIM unlocked or flashing a ROM won't change it - actually nothing will) in that the partitioning and radios are different. In this way, your phone will always be a "Sprint version" M8. The difference is important to understand, not just for flashing ROMs; but if you decide to s-off the phone and flash another versions RUU or firmware, it won't work, and you may even brick the phone. So don't do it!!!
If you flash a ROM that doesn't specifically support the Sprint version, it won't boot. You may be able to get those ROMs to work by flashing the proper kernel, but you can probably find more discussion about that in the "Sprint" specific M8 forums, from other Sprint version users, etc.
Custom ROMs will almost always have tethering enabled. Even if it started as a Sprint-based ROM, the dev will most likely have removed the tethering restrictions. That's one of the things that makes these ROMs so great!

Service Menu on custom ROMs?

Hi guys,
I'm looking for solution or clear answer.
Do you know any custom ROM with access to Service Menu (same or similar as on stock ROM)?
I need option to force specific LTE Band, and 3G bands as well. In stock ROM it works realy fine and I can check many things about connection to network.
ARFCN, bandwidth, LAC/TAC, CI, PSC/PCI, neighbours etc.
Any hint which parts of system has influence on service menu ? Firmware, kernel, some APKs ?
I just tried RR-5.8.2 (Nougat 7.1.1 based on LineageOS ) it works realy fast but without this option I must revert back (flash) to stock ROM.
I made few hours reaserch on google and XDA but nothing specific about that.
Custom ROMs don't have the framework needed to have the hidden menu. Plus, it's CUSTOM, so there is no way in hell you can get anything "official" on it. Oh, and plus the fact that the service menu is not just an APK, but it integrates way more than you could even think with the OS, it's "made to size" so to say.

You can use stock based custom ROMs like Fulmix.
Anyways I'm almost certain AOSP had a hidden menu on itself for forcing LTE band and similar controls, try looking for it and see if it has the settings you need.

Thanks for information, yes Fulmics has access to service menu - works fine.
But it is visible slower than new roms 7.1.1 based on lineage and now I can't install ASOP based on Nougat. I tried few times but no success.

Yes stock based ROMs are slower than AOSP ones. Why aren't you able to install Lineage or similar now, you should be able to without problems?
Also there is plenty of hidden service menus in AOSP as well - one of them is *#*#4636#*#* among others.

Three ROMs based on LineageOS works realy fast but as I wrote above it hasn't Service Menu ! Because of that I ask which part of system is responsible for Service Menu. As I understand it is dependent of framework from phone manufacturer, and integration this function between parts of phone system (ROM, modem firmware, kernel, etc.).
Hidden menu isn't interesting at all. I need RF functionalities available only in service menu (*#546368#*855#).
(sorry for my bad english - I'm not native speaker)

There are a lot of RF frequencies in the hidden menu. Have you tried it? What exactly do you need?

In most ROM code 4636 shows information about Phone. I need selection of specific band on 4g / 3g, rat selection. And technical info about connection to bts / nodeB. I wrote it in my first post.

You can select a specific band from the phone information tab and the hidden menu I told you. If you need other options I'm pretty sure there is another menu for that.
If there are connection options AOSP should have them somewhere, as they are necessary for the phone to operate.

Assuming you unlocked your bootloader and have TWRP
IF WIPED SYSTEM/USING AOSP/WANT TO ENABLE SECOND SIM ON G8141
Flash This with a newflasher
CONTINUE:
P.S. Keep a TWRP backup of stock rom on your phone, so you won't need to use newflasher again.
Install this on top of the stock/stock based rom (like Tomahawk Project)
Don't forget factory reset!

[Freedom of choice]
FOR MAXIMUM SECURITY:
Keep it simple, without ROOT
Install F-Droid and explore open source world. Download APK and send it to your device. I removed browser, pick your own
At your own risk:
If you want download apps from playstore anonymously, try Aurora Store
Want to get accurate Network location and some of the Google apps working properly, then install this Magisk Module
To get Network Location working, signature spoofing is needed. You'll need this or this edXposed module
If you think my work was for nothing:
Install Gapps and never visit this thread again
Changelog

Fixed broken GSM + Data
Privacy made Easier
Let's find a balance between security and ability to use apps which we have to.
Most of us have people who use messengers we don't trust, but we still need to communicate with those people.
Another CONCERN is a fact that most of the apps rely on google for push notifications. Google get all the content, no matter how secure your messenger is.
If you don't have Google Services, then you have problems with notifications. Here MicroG will help us.
So, let's make a secure environment for apps we use, but don't trust.
You gonna need:
This rom installed
Magisk + "microG installer Revived"
Shelter
Let's do it!
Open Shelter app and let it create work profile.
Then you need to make sure install some apps in there:
If you install Aurora Store inside Shelter it will allow to easily manage apps from Play Store.
You can clone magisk to shelter( enable multi user in the main app first, then clone) and install firewall inside the shelter.
Update:
Another way is to install vpn inside shelter and enable kill switch. So apps inside shelter only won't have internet access unless you enable VPN.
I use protonvpn, it give 3 countries for free and it's more than enough for average user.
Beware that when VPN is outside of the shelter, on the mainland, apps on shelter will bypass it, so you need to have clients on both. You may have 2 different VPN clients enabled if you need to.
What do we get?
See "Contacts" and "Files"?
Those are seperate from the mainland, so you can just add your relatives' phone numbers and WhatsApp will only see those.
We are LIMITING ACCESS TO FILES AND CONTACTS.
Plus we can easily freeze those apps, or limit connectivity with a firewall, or vpn.
Result:
You can use apps, that brings vulnerabilities or privacy concerns in a locked,controlled environment.
Still receive notifications without sending them to Google.
Or you can try VMOS, at your own risk of course
Short message for each of you.
This rom is a result of a project which aim to strip android back to it's core, so WE CAN BUILD IT THE WAY WE WANT IT. Not the way market researchers say we want it.
In short, this ROM is a prototype of community communication device.
Everyone can join the digital freedom project. I am sure each of us can help a cause.

Not real,but VM
If you set "apply on boot", you will notice that boot animation will become smaller ,but it's the same trickery as adb commands.
g8141 does not work, reboots right after sony logo no bootanimation.
p.s. flashed over .107 stock rom with twrp 3.2.3-0
edit: installation guide is a bit vague, do we MUST flash this? https://androidfilehost.com/?fid=4349826312261694774
It says
IF WIPED SYSTEM/USING AOSP/WANT TO ENABLE SECOND SIM ON G8141
but I didn't wiped system nor using aosp nor want to enable second sim
second edit: Needs few reboots before booting to system, seems to work like intended.
Some suggestions:
Please find a solution to Automatic reboot when sim tray is removed, since I don't use dual sim and switch SD cards frequently it gets frustrating so fast. Thanks in advance.
Qualcomm Device Security still persists on this rom, it has an apk under vendor\app\QualcommTelemetry(?)
Video Enhancement is not working, at least on settings preview.
VERY USEFUL: Show charging current on lock screen, existenz rom had it.
Dark/Full Black System theme
Boot time is unacceptable, it takes around 2 minutes for normal boot, whereas even in a bloated stock it took around 30~ seconds. It is due to your framework changes and deodexing. However, I've been able to restore optimal boot time by changing all frameworks.
@undefine,
Yeah, boot time is longer because because of deodexing. Frameworks are untouched though in this rom.
If you want Video Enhancements, then you need to go back to android 8 and istall drm patch.... Since they fixed the camera on Pie nobody really bothers with other drm related things...
Agree on the dual sim reboot thing, it's annoying, but I have no idea how to disable it for now. If you really don't need to dual sim functionality then you can try flashing this rom on top of G8141 version and make sure you got kernel as well.
Theme is overlay, adding functionality to the lock-screen require modifying services.jar to disable signature (super user mod), both are security risks... You may flash existenz on top and remove what you don't need. At your own risk of course

I think boot time is not because frameworks are changed but some are missing, I just reflashed with everything in stock framework folder, it seems to be blazing fast as normal. I'm actually surprised it booted that fast even with Deodex.
As far as I remember Video Enhancements worked on stock 9 at least on my device, I have my drm keys though since I waited for a proper ta backup. However it is not a must feature either.
I'd rather flash opengapps full package than flashing existenz over this rom . I will look into some other tricks for showing charge current, maybe some xposed module exists?
Anyway, thanks for your contribution to this device. Cleanest stock rom I've ever used (besides one bloat called Qualcomm Device Security which I immediately removed).

Question How to allow VoLTE/VoWIFI on my P6P in non-supported country?

I am really interested in using my P6P which is sitting for months in my drawer, because I am unable to use VoLTE/VoWIFI in my country (Slovakia). This is crucial to me and to my work. I don't care that much about 5G as coverage is big enough.
I have been reading some articles and threads, but I don't have the crucial questions answered, so I will give it a try here:
1. Do I need to root device to enable the two options I am asking in first place?
2. If I will root it, will I be able to use the Company Portal, Gpay and banking apps?
3. Can I update new versions of Android when my phone is rooted? I assume it would have to be done via sideload not via OTA.
4. Can anyone point me to proper thread which will lead me through the process in achieving all this successfuly?
Thank you.
There's a custom with custom avb key (this means you can relock bootloader after Rom install) that has VoLTE tweak enabled for unsupported country within the Rom. 5G is also tweaked to be enabled.
And after that, future update is via sideloading in recovery mode, no need to re-unlock bootloader
Go check out the Rom in telegram here https://t.me/hentaiOSRaviole
That seems like custom ROM - I am not really interested in that. I prefer it as stock as possible.
I only found this.But it's only for Chinese ISP(and it works fine for me) . It's a magisk module which modify mbn_sw.txt to enable VoLTE for Chinese Operators .
GitHub - CHN-MuXin/MagiskModuleEnableChinaForVoTELtoPIxel: This module will modify mbn_sw.txt to enable VoLTE for Chinese Operators . Theoretical support for all Pixel models and Android versions

Yup. Custom ROM but no additional features like other custom ROM. Their aim is just to improve the stock ROM.

Degoogled/Privacy-oriented ROM for VoLTE on Verizon? H8314

Hi, I'm having a heck of a time getting any ROMs that will work well enough for my needs, which are as in the title, I need VoLTE on VZW and would like a privacy oriented ROM.
I've tried:
1313-0031 Customized US from Xperifirm: LTE connects straight away and VoLTE works, but obviously not yet degoogled or customized
e/OS R: eventually connects to LTE and I can text, but calls return "Server Unreachable". I can't find docs on fixing that or patching in VoLTE support for VZW
SonyAOSP 12 and 13: LTE symbol appears in notification bar, but no touchscreen so I can't test whether it actually works. Bug reports on this seem to still be unresolved.
SonyAOSP 11: No LTE whatsoever
Using newflasher to try to add oem*.sin files to e/OS and SonyAOSP11 installs: I'm not sure if this method even does anything, I noticed no change to e/OS and AOSP11 refuses to boot (corrupt message in AOSP bootloader)
Are there any ROMs which are likely to work for my needs? It's also likely I don't understand the process of patching in the oem*.sin into a different OS, and am unaware of other methods I should try. Or at this point is my best bet to root and manually customize the stock firmware from Xperifirm?
Thanks for any help and sorry if I'm asking noob questions, I haven't owned a phone I could flash in years
