Volte Problem

I installed a RUSSIAN AOKP ROM two days back.
Since then my volte isn't working even after changing ROM.
I have even flashed latest MIUI Dev by fastboot, volte wasn't even working on it. What to do now?
The ROM that I installed:
https://androidfilehost.com/?fid=961840155545587180
I had the same problem. I did everything to solve this problem. then i flashed arvansoft miui rom. Volte wasnt working at first.
then i reset to default in apn setting and rebooted.
volte was working in arvanasoft. then i flashed crDroid rom and volte is working fine now. :good:
you can find arvansoft rom by searching "aravansoft redmi 3s" in google. I cant post links, I'm new here.

Sleep of death in all Nougat ROMs

The global trouble with all nougat firmware
Hi guys. I amn't alone, I met 10-15 users at 4pda with such problem.
We have the bug at all nougat roms by any devs with different trees...
The sleep of death.
Personally I notice it after/during mobile internet using, but I'm not sure. For long time at home(for a week, for example) with WiFi I have no troubles. But if I am anywhere without WiFi and use 3g(don't have LTE in my country), my phone "sleeps" for some times during just one day... It isn't powered off as it's needed 10-15 seconds of button pressing to turn it on at least.
As the ROM and developer has no meaning I guess that here are the errors in the kernel. @fir3walk says that here are many bugs in our nougat tree and perhaps the trouble is involved in last_dmesg... Or some system force stopes, dozes work improperly.
Not many users have this trouble but it exists an a fact. So it would be great to detect an error and try to fix it. Perhaps not in nougat, at least in new Oreo(I haven't tried it yet so no information about this bug there). We have many ROMs, they are updated for some times a week, new roms are rolling out... But the bug stays still.
If someone else has such problem, write here. Perhaps somebody has any ideas and together we will be able to find solution...
So, all the devs who can detect an error, write us... Any tests, information, logs, etc.
P.S. By the way it is impossible to write logs of powering off(deep sleeping) via logcat or another's. If I run the logging I have no "sleepOFdeath".
It is really global trouble so let's try to fix it together.
I'm sorry for your trouble.
Lets start by figuring out which device is in question
I have a 3s prime and never saw this issue.
So do you have a 3s or 3x or 3s prime?
Hello OP, can i ask if you installed that MIUI Ported ROM based in nougat? Because when i installed it (twice) y faced this issue in every rom that i flashed afterwards, then decided to clean-flash miui fastboot rom and the problem was solved.
Maybe that's your problem.
i face it in rr rom but no in dnd rom
Guys did anyone here with the sod, flash global stable/developer in edl mode?

Hello. No, I didn't try miui based on nougat.
But other users say that they notice such trouble at miui(7 android) as well.
So it isn't the cause...
Also about my phone:
Redmi 3s, 2/16, 2016030, FPC, aa1 motherboard.

Will try to flash via miflash, as I faced no problems before this SOD at 7.1.2. Always flashed my phone via twrp.
By the way, guys, my 3s sleeps well on nougat, but it isn't econom in active mod.
For example, I have made a record at our device at 6.0.1 version - 17.5 hours of screen. Nougat isn't so optimized by now... 10-11 as maximum.

It it solved my voLTE works now
Having a serious problem.....I'm running pixel experience ROM now but I have a tried nitrogen OS, ressurection remix ROM, Lineage OS 15.1, Viper OS (nougat), Lineage OS 14.1 and many other ROMs. Volte was working fine few days ago but for the past 3-4 days it was not working. I thought it was a problem with the ROM so I changed the ROM but still got the issue. And today I came to know that my device is showing IMS registration: unavailable
Voice-over LTE: not available and some other things
I tried messing with APNs and flashed some volte patches but still got no luck. Then I tried searching on XDA forum and know what I tried every possible method in almost all the threads and still not able to get volte. Tried searching YouTube for IMS registration and tried googling it also but still the problem is there.
Help me out plzzzz....

Maybe you need to write IMEI number again?
Does it show there when pressing *#06#* ?
U may try going back to MIUI 9
And then back to your favorite ROM
I did every single step mentioned above. Even my IMEI number is all good. But VOLTE problem reamins the same.
During the first boot...VOLTE was there, and it was working. Even when I Rebooted, it was again there and still working. But when I Power Off the device and then powered it on, VOLTE was gone and I was unable to call.

I did that too and thrice bt the problem remained unsolved. As I mentioned, it worked during the initial boot of any custom rom, even after rebooting it. Bt when I powered it off and then booted it up, VOLTE was gone.

Yeah happens with me to but now m using Xiaomi.eu miui 9 ROM bro use it for some days and flash another ROM voLTE will work fine as it creates a strong bond between firmware and ROM that miui 9 official doesn't and it has more features than it miui 9. So give it a try

Will Jio work?
Use this trick:-
Flash any miui rom v8 or v9 & boot into system..
Now go to recovery wipe all except storage.
Now flash any custom rom i suggest lineage 14.1 & boot into system..
Now again go to recovery go to wipe , advance wipe & wipe only system
Now flash any MIUI rom then wipe cache & dalvik
Now reboot...
Volla your volte now works...
I tried 2 times & all time it works....
If it works for u hit thanks..
