How to enable Volte on custom LOS 16? - Huawei P20 Pro Questions & Answers

Hi everyone,
I just flashed LOS 16 & have everything working except for volte on a SIM card. It was working fine with stock EMUI until I flashed LOS. Things I have tried/done:
Modified build.prop to toggle everything related to volte ON
Phone Info screen shows Volte & all other options toggled ON
Tried a different working SIM from the same provider but had no success
Data works fine on the SIM. It's just that I cannot receive/make calls or sms.
Just wanted to know if Volte is even supported on LOS 16 & if yes, has anyone managed to get it working. TIA.

Thanks, you solved my issue! I so wish you came online earlier, would have saved me so much time researching.

Glad your issue is solved too. It was a simple fix tbh. I fixed that Volte issue a while ago.

Any of the Nougat modems and bootloaders will work just fine.
During twrp flashing this rom the modem and bootloader will be
replaced automatically any way with the latest beta 5 modem
and bootloader.
Good luck, very Merry Xmas
and have a great day!.

You CANNOT flash this rom if you have a Tmobile G935T/G930T phone.
This rom is made for the Exynos G935F/G930F international phones for
people who are on the Tmobile network in the usa and want wifi calling,
volte and rcs.
Flashing this rom on a G935T Tmobile phone with either twrp or flashfire
will result in a soft brick and you will have to Odin flash your phone with
the stock original firmware to get it back to working condition.
Sorry about that...
Have a very merry Xmas!
Confirmed this works overseas also. Works great!!

Do I need to flash the no-verity-encryption.zip and if I do, when should I flash it, before or after flashing this ROM

If you are coming from another Nougat 7 rom there
is no need to flash the no-verity encryption.
If you are coming from a Marshmallow then yes,
and flash it before flashing the rom.
Good luck,
Have a great day!
I really liked it, seems too light. I love the fact that we can choose samsung bloatware to remove and everything has a great explanation in the Aroma. I have two things though. First of all I am using G935FD, I do not think this is a problem, but it could be you tell me. concerns are:
1. There is no app lock under Advanced feature in settings, I would really love to use it.
2. When I go under Device Performance, under Security, I see the shield sign; however, it is blank with no text and that is the only thing visible. I know from older ROM I've been on "OnTheEdge" that this should work as an antivirus. I also had the same issue with Helios.
I have LTE, wifi calling.VoLTE, and can access my SDcard without being in recovery mode, as was the case for the two previous nougat I tried., beside the two issues above great great work man.
any chance of a flashable zip with the csc and files required for VoLTE to work?
I'm getting text messages twice with the stock messenger app. Both recieved and sent show up twice. I've cleared cache, full wipe twice and still the same. Textra works fine, only receives one text. Anyone else seeing this? Any suggestions?

Hi.. another questions.. Does this ROM locked the 2nd sim for G935FD? because I know my 935FD is international unlocked but seems like sim2 only working for TMO sim? Can you confirmed? Thx

I had the same issue when I was on the Xperia z3 dual SIM. It mostly occurred when I used the messenger app by Google. I'm still using it now, but haven't encountered that issue. It's slow in receiving group messages, if you're connected to Wi-Fi.
Thank you for making this ROM. This is exactly what I've been looking for.
Unfortunately, it doesn't work for me. I get a "Invalid SIM card" notification and I'm unable to make calls or use data even though I have a good T-Mobile USA SIM card that works with other ROMs. When I go to "Mobile Networks" in Settings->Connections, I get a "Invalid SIM Card" toast. I did a full wipe during install.
My phone is a dual SIM version (G935FD) and I have two SIM cards installed (second SIM card is T-Mobile). It looks like the modem that ships with this ROM is only able to support one SIM card at a time. When you install the second SIM card the phone is not able to use either one of them. I reports that a SIM card is carrier-locked even though it's not.
I was able to recover by restoring a NANDROID backup that included my previous EFS partition.

9.0.6 Instant Update if you dont have it yet.

My phone is the non-Tmobile version.
Simply VPN through Germany via your favorite VPN (I did mine through psiphon pro - Turbo VPN should work too) and BAAM!!!
Thanks ! Used Private Internet Access and it updated aswell.
It worked.. But i cant unfortunately..
Im rooted and dont want to loose everything..
Hmmm I tried a couple but without any luck... wondering if I'm doing something wrong. I have a global version completely stock. Any suggestions would be greatly be appreciated thanks.
USA didn't show it when I looked to update on Wednesday but VPN to Canada and picked it up 9.0.6.

You can update and keep the root as well.
I just did it following the guide in another thread.
Everything went smoothly and the process is quite quick if you have, as I suppose, Magisk installed.

Next time you'll make it
9.0.6 OTA available in USA . I received it a few hrs ago.
Got mine last week with a VPN through Canada.
Wonder if this method works with the latest 9.0.7.
Update: apparently VPN is not working according to main page post.
Update 2: according to other thread, free VPN app, connected to Germany and received the update,. Nice

Question No network on developer preview 1 and 2

Hey after flashing Developer Preview one I got no network connection.
My device is a Chinese version with global Rom.
NE2215
I also tried flashing the Chinese version and the EU version and it didn't work either.
Any ideas?
All the settings in the connection options are greyed out. I cant set the APN manually. Everything is greyed out.
you probably lost your imei. sorry to say, but you likely have a very expensive brick on your hands.
Got similar problem on 1+. The imei is available but both sim cards do not find network. It occures not only on developer preview but on all ROMs

if you lost the imei, then no you can't fix it unless you previously made a back up. go into settings and checkk if it's still there or unavailable
My problem is only happening in developer Previews of android 13
After I reverted back to android 12, everything works again. Dunno what it is. I did a log the last time. Maybe that will help someone.
I can active the sim with entering the sim pin. The sim tries to activate, but it always aborts. So the sign for the not entered sim in status bar is disappears and comes back again. Same with the options in network settings. They randomly grey out and come back again.
I got a Chinese version flashed du NE2215. So I got NE2210 hardware with NE2215 Rom. Maybe this causes my problem. Cant either flash NE2210 or NE2215 developer preview. Both have the same problem.
why making those experiments with the phone

The question is not why I do such "experiments". The question is, why it doesn't work.
If I would like to wait for final release, I would not be in this forum.

Nope, you just can update via local update. A nice how to is on the OnePlus forums. There are also all downloads you need

Yeah, because you have a higher version of Android 12. You have to downgrade first with the android 12 package.

Did not have any problems with locked bootloader. For me it worked.
Dunno what this guy flashed
All in all you do this at your own risk. No one guarantees you anything
And read the post. It has nothing to do with locked bootloader. This is when guys flash without knowledge

Question S21 Korean issues

Hello everyone and merry Christmas
I got an S21 Ultra and facing some Issues
Seems to be the Korean version with no esim and caller ID for incoming calls isn't matching the name since I have all my contacts in international format

Any way to solve my issues, preferably without factory reset?
Thanks

It's a bug in Android 13. I did all the tests, even the hard reset, nothing to do. I also tried to change mobile operator sim.
I asked Asus support, but they didn't give any answer.
Downgraded to Android 12 and that's the only way it works.
