Cannot make phone calls on any Nougat custom ROM - X Style (Pure) Q&A, Help & Troubleshooting

I went from stock Nougat to several variants referenced here
Whether I'm using RR, Nuclear, etc.......the t-mobile signal is so weak that I'm unable to make phone calls.
Using TWRP 3.1.1. All installs have been clean, wiping system/cache/dalvik/data on each.
Is there something I should be checking or installing to fix this?

I may have solved my own problem.
For those who have the same issue, disable VoLTE:
Settings - Wireless & Networks - Cellular Networks - Enhanced 4G LTE Mode.

Cellular Network Not Available

[ Suposed to do with installing microG Services Core & GsfProxy, FakeGApps from Xposed and MozillaNlpBackend.]
After following steps in this thread here where is not support to get the things back to previous state, my phone [G900M, Resurrection Remix v5.7.4 based on CM13, rooted]. Also I realized that is a threat for S7, but all apps seem to be standard.
Now phone shows the following issues:
1. Cellular Network Not Available... -Network State: Disconnected/ Service State: Voice: Out of Service/ Data: In service. Have data connection, SIM amd operator detected, not able to call or sed/receive sms
2. MAC Address changed to: 02:00:00:00:00:00 Means that something to anybody?
3. IMEI has changed in phone status. Plus there is no phone number
4. Cellular network switch and data switch are linked. That means if I Switch on one, the other is also on, but not possible to switch in different mode
5. LTE discovery app shows: Cell Radio State "connecting". It seems like the phone stucks on this step, not being able to get network
Done: Checked APNs (it doesn't let me add new ones)- are ok, Wiped- nothing change, reinstalled rom- nothing change, flashed model modem- nothing change.
Pending: Downgrade to stock rom (lollipop 5.0)
How can I know the EFS Partition is not affected? Could be that situations a signal of that?
Does a stock rom restore EFS in case of damage?
/efs was not affected, did you resolve the issue?

Jio Sim in a "Disconnected" State - HELP PLEASE!

I was on stock debloated ROM and flashed the Magisk and then the Elemental X 2.02 from the link of https://forum.xda-developers.com/g5-plus/development/kernel-elementalx-1-00-moto-g5-plus-t3614211. Then, the Wifi starting acting weird by not connecting to a very active Wifi signal and connecting very late. Then, when I searched for a solution there was a "wlan_custom.zip" that needed to be flashed (I found this in the same Elemental X forum in the above link). Later, when I rebooted from TWRP, my Jio signal is gone. I have tried all the ways and means to get it back, but nothing seems to be working.
-- I tried fastbooting the original stock firmware - no signal.
-- I tried flashing an Oreo ROM to get that 4g signal - no signal.
-- I tried flashing the full stock ROM zip file - no signal.
-- I tried creating a new APN and select that - no signal.
-- I tried putting the Jio Sim in slot 2 - no signal.
-- I tried putting a new Jio Sim in either slots - no signal.
Could anybody please help me?

Thanks. Can you please confirm if flashing that would bring back the Volte as well?
From what I experimented, I followed the steps at https://forum.xda-developers.com/g5-plus/help/restore-imei-0-moto-g5-xt1687-t3739808 and the 4g signal is back but with only LTE and no Volte. Because of this, I am unable to receive or make calls on that 4g SIM; only the internet works out of that.

Yes the tutorial you followed and what I'm suggesting, both restores the 4G network but no VOLTE, by the looks of it, I don't think it's going to work now

[Q] US996 on Verizon issues

I have several issues with my US996 on Verizon, running LineageOS 14.1. (I'm not asking in the LOS threads because I figure more people here know the details of this device)
The main problem is I can't get SMS to work unless I set the preferred network type to CDMA or CDMA/EVDO only. I have been using the "VZWINTERNET" APN.
Any time I set an option that includes LTE (including the "Global" setting), SMS/MMS stops working.
Also, the signal indicator works strangely, oftentimes when I have strong signal the signal indicator shows 0 bars.
Lastly, many of the fields in Settings/phone info/SIM Status are blank, eg phone number, signal strength and service state. (Perhaps this is a CDMA/Verizon idiosyncracy since the SIM is not the primary auth to the legacy CDMA network?)
Do I need to flash the VS995 radio to this device to address these things? Is that even feasible? What about what Verizon calls "Advanced Calling" options? Ideally I would love to have VoLTE and WiFi calling as well.
Thanks.

If youre device is abr0 you can use the patched dll version of lg up. https://forum.xda-developers.com/attachment.php?attachmentid=4233875&d=1502007613 to flash vs955 firmware. I have found that the this version VS9951BA01 is the one has fastboot mode and can get to recovery if you want to use dirty santa on it. or if you get to the you have 9 attempts of 10 to enter the passcode. you will then need to factor reset to get the data formated. But this link has the full instructions. https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

Thanks for that tip, I will read up on it a bit later.
The main reason I got a US996 rather than a VS995 is the lack of an officially unlockable bootloader on the VZW variant and having to use an exploit to unlock/root it which only works on old firmware leading me into a potential trap if the device ends up in a state I can't either unlock/root or return to stock from.
I already unlocked the US996 bootloader - will that get reset if I flash a stock kdz onto it?
I tried using LGup shortly after I got the phone but I was having problems getting it to work on my Win7 workstation, perhaps I had the wrong version..

[Question] Volte enabler on custom rom

Hello people, got a nasty situation that I'm trying to fix on a custom rom based on LOS (crDroid to be more exact) and that's the Volte enable.
Running stock OOS 9.0.17 managed to do it using this guide: https://forum.xda-developers.com/oneplus-7-pro/help/force-enable-volte-vowifi-t3934227 but since the OP logkit doesn't work on custom ROMs can't access *#*#800#*#*/*#*#801#*#* service menus I can't really use that anymore. Using that guide I managed to activate Volte by activating modem connection with Vodafone India settings. On Rom I'm using now, the only menu I can access is *#*#4636#*#* that shows me the connection type is active at the time, but no working Volte. When I use my 1st sim to make a call, connection switches to H or H+.
Another thing is that on INFO menu the connection type shows after reboot like in screenshot attached even if I have my volte switched on.
Also from that guide I've linked, I can't find that VoEnabler magisk moduke, so I've added the lines manually to build.prop (lines found on GitHub module page)...
Anyone knows a work around for it? Or a way to switch the LTE band to the one Vodafone India use to match the band Orange Romania uses for Volte?

phone says there's LTE service, but disconnects when making a call and cannot receive/send texts

I installed the latest lineageOS 19 version, rooted my phone then ran into this problem where the phone says i have service, but when i place a call it wont fully make the call. Then my mobile data will X out and i get pop up error saying mobile service is unavailable. I then tried lineageOS 18.1 and arrowOS and same problem persists.
formating between installs obviously.
I have looked at every option on this phone and tried combinations and everything in the network/system/ everything and still not working.
The process was actually very simple since i have some programming experience. Other sources mention possible baseband issues? On the fastboot screen it shows a baseband version. all the information there appears normal. I only flashed the boot image one time to root and didn't mess with any other manual flashing processes. Just used twrp. I didn't quite understand twrp at first and therefore didn't get a backup using it... iused adb to make a backup which apparently didn't work so Im lost and hope someone could help me out here. please and thank you!
If i may add I can use mobile data just fine, i can browse the internet and such (with wifi off and data on only) so i really dont understand. Is this a normal issue to have when using custom roms? did I trip some security that blocked me now? any input???
I wonder, though, this moto g7 is an A/B partition thing. so if i understand correctly, flashing twrp would not work and thus why i did not do that. it makes sense. But should i try flashing it, booting into it then installing lineage? even if i did i feel like that would give me same issue considering the method i followed got me into lineageos, plus root checker said i was rooted.
What I can tell you is what I had to do in order to get LTE (voice calls) running on my G7 - I was forced to switch over to LTE because AT&T turned off 3G here in the US and 4G without LTE is not good enough for voice calls:
Get the latest stock firmware and install it using e.g. Lenovo's "Rescue And Smart Assistant". That will get Motorola's Android 10 on the phone.
After installation, go through setup and actually make a call (calling your mailbox is fine). Then check your ims status (*#*#4636#*#*, goto phone info, pull ims status) to see that ims is actually working.
Shutdown the phone and start installing LOS (use the partition copy script too to make sure that the partitions not touched by LOS installation are updated "on the other flash bank").
Go through LOS setup, select a valid APN for your setup, set "LTE only" or "LTE / WCDMA" for the network and make a call. You should be good to go.
Again this is what I had to do to get LTE working with AT&T USA. YMMW.

I know this is way late, and you probably already figured it out. I didn't share the no text problem. The Problem isn't just the "LTE" setting itself. There is one more option(some Roms show it, some don't) I believe its in the phone app settings? VOLTE must be checked. I have noticed Some Roms do have this option and some don't. when volte is checked, it'll keep your data/internet on during a call, some Roms that option won't show up or isn't available. I haven't used G7 in a while, but I do remember the problem and how to fix (on my phone anyway).
