Good evening,
the problem my be known, but till now, I have not found a thread where a solution is presented. Now let's dive into my problem. Some days ago, I experienced the problem, that I am frequently using my network signal. Till that time, I was using the Firmware version 10.0.6 and the RR 7.0.1. I thought, maybe an Firmware update would resolve this issue, and I flashed the Firmware version 10.0.7 but the issued did not get fixed.
Yesterday I did an clean install of the ROM with the following steps: Firmware 10.0.7->ROM RR7.0.1->recovery TWPR->reboot recovery->Gapps->Magdisk->reboot system but even now I'm loosing my network signal from time to time. Is there an solution for this problem? Tomorrow I want install the SyberiaROM in order to verify if the problem is still present.
What could be reason for this problem? I already checked my IMEI numbers and both are matching with the sticker on the phone. Could it be, that my SIM tray is defect?
I had that problem and tested everything... Had to change my service provider to get stable signal.
You can try installing stock Pie, then downgrading to stock Oreo. If signal is good on Oreo, it is not a hardware issue. But if issue is still there, try changing your carreer. Still don't work? Bring your phone to the service center.

Since January I am having the same problem, I can not make calls or receive them either.
After I installed the ROM clean the problem is still present. When I lose my signal, I can hit the airplane toggle twice and then I get my signal back. It's not really an workaround.

My Nexus 6P has begun to periodically lose all cellular service (Verizon LTE) for no apparent reason. If I reboot the phone, service is restored. Turning airplane mode on and off doesn't help.
My phone is currently running Android 7.0 build NBD91V with the most recent patch on 12/5/16.
Has anyone else seen this problem or know how to fix it?

It's a known issue. If you Google it you’ll find others including myself with the same problem.

The OP of that link is on Project Fi and on different carriers than you so it may not be a complete match with your issue. The new January update N4F26J is designated specifically for Verizon devices and includes a new baseband version (radio 03.79). The radio apparently resolves some issues specific to your carrier- so I would start there. Update your phone and confirm you are on the new radio. If it was working fine earlier, you may also want to try reverting to an earlier radio from a time when your phone was working normally. I would also recommend trying LTE Discovery. The free version has most functionality you would need to identify all the towers in your area, what bands are available and the signal strength of each. Good luck. :good:
So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?
Hi everyone,
I've been having a problem since yesterday morning. Everything seemed to be fine with my phone before I flashed a custom rom. I was using at the moment MSM Xtended and I flashed the latest version of CrDroid. After flashing that other custom rom and booting, my phone had no network signal. All it reads on the status bar after that is just "No service". Of course, I removed the SIM card and reinserted it many times but that did nothing.
I've already tried flashing another rom (the latest AICP rom) and even going back to the one I was using at the beginning, but still nothing. I even tried reflashing the NON-HLOS.bin file and erasing modemst1 and modemst2, but it didn't do anything either. I also tried flashing this deodexed stock rom and booting. Interestingly, that kind of fixed the problem, since it recovered its network functionality. However, after reflashing an Oreo custom rom, it loses it again (actually, I've done that a few times today, but the last time I tried flashing the stock rom, for some reason it didn't fix it anymore). I don't know if in this case it's worth mentioning it, but I've tried checking my IMEI on both, custom roms and stock rom, and it's never been 0 at any moment.
TL;DR: My phone lost its network signal after flashing a new custom rom and I have no idea why. If anyone could somehow help me, I'd be really, really grateful.
I have had this happen so many times it is not crazy LOL. The best you can do is find a rom that it happens the least. For me it has been AOSP extended. Signal has been great. It is a bug that I dont think the devs even thought would happen with 8.1 roms. It will happen to everyone at some point if we stay on these 8.1 roms i guess until we get a workable 8.1 stock rom. There will be those who chime in saying it nevver happen to them but it will eventually.
Well, it's nice to know I'm not actually the only one then, I guess. But is there nothing I can do? Since I can't seem to get it fixed even by flashing the stock ROM anymore and flashing AOSP extended didn't seem to help at all either
I know brother there is no rhyme or reason it just happens. I am hoping when 8.1 stock comes out for us there will be a new batch of 8.1 custom roms without this problem. Right now i am on extended and havent had any signal problems for a few weeks so who knows.

Okay. Luckily enough, Oreo stock ROM doesn't look like it's gonna take too much more to arrive... Or so I hope, at least. Thanks
I was using LinageOs and it was working great. Then I decided to install DolbyAtmos and for that I flashed Magisk . Suddenly i had no network but my sim cards were detected , IMEI was there but no network on either sim whatsoever. I tried reflashing the LinageOs and PixelExperience ROM but none worked. So I tried flashing(ADB) the stock firmware only to lose my IMEI . After reading this post I tried Debloated ROM and my network was back. I should have stopped at that point but I tried to return back to stock again and lost IMEI again and now I have tried Dbloated,LineageOs , PixelExperience , AOSP Extended , but none helped me getting back network . Now I am stuck with this phone with no network , I had a backupp of my system before I flashed Oreo ROMs (with EFS) so I can get IMEI back but no network. This phone was my daily driver and now I have no idea what to do.

Everything you said is exactly as if I had written it. I did all of that and now I'm exactly in the same position. No idea how to fix it yet. Still, if you managed to find a solution somehow, please write a reply on this thread again

No success yet , but read on some posts that different baseband could be an issue.
Solution I've tried and worked 100 %
Hi bodies,
You can turn off your phone,
Go to fastboot menu by pressing and holding power button and volume down button in the same time.
Roll to "Restart Bootloader" with volume up/down and validate with power button.
Now select start and the network is back.
see you !:fingers-crossed:

Hello, I am from Spain and I have the same problem and I can not find a solution.
It might sound a bit obvious but check your APN, after one update my APN was wiped and I had to manually put it back in again, I'm UK on SKY.
I have the same problem. Can't find a solution anywhere. Sucks.
same problem, we need to back to Oreo?
I went back to Oreo, changed to a custom rom, replaced the antenna, and nothing ...
And obviously before all this check the APN
ridiculous
It is a ridiculous situation.
What is APN ?

you can install the February update then reboot your cellphone if it works, congratulations on your efforts. if that case still continues you can reset your network card from setting the signal reset, bluetooth and wifi, and then reboot ... and enjoy your repair effort If it's not sweet enough, you can reset your phone's factory and reboot. enjoy it.

This issue is still not resolved after the March update which I waited 6 weeks for.
A phone which cannot make or receive calls?
I would never, ever by a xiaomi phone again.

Hi There, I'm facing the same problem here, let me share how I fix mine, maybe it would help your problem too.
My device was on the january patch and Pie ROM, I've mod the camera API and I cannot receive the OTA updates. yesterday I manage to lock the OEM via ADB/CMD so I can get the OTA (This was a mistakes since you can't lock the OEM while you have your system modded). My phones showing "system has destroyed" message after.
I'm panic and what I've done next is I unlock the OEM and flash it with the only fastboot ROM I have, which it was the Oreo ROM. My device can boot normaly, loosing the mobile signal (I've tried to switch the SIM Card and it still the same, I've check the IMEI and there is no problem with it), and every time it restarted, the device going to a bootloop.
the next thing I do is download the Pie Fastboot ROM I got from this thread and flash it via Mi flash.
I flash it using the "clean all and lock" method. Lucky me, after the phone booting up, I can see the signal bar again and there is no problem in receiving calls or SMS.
Hope this can help
Hello
Could someone help me?
a2017u b20 stock. Flashed via EDL
I have a2017g version. but i need wifi calling working(and it works perfect on b20).
But i have some strange issues with modems.
I tried a lot.
ZTE_A2017X_Oreo_V2.10B12_Gmodem
ZTE_A2017X_Oreo Gmodem for 02 version
ZTE_A2017X_Oreo Gmodem for 03 version
They worked, and wifi callong was working too, but - funny bug - when someone calls me from iphone X(exect iphone X) then i cant hear him. and after i call back all is normal. But cant receive calls from them.
The only modem, on which there is no this bug is ZTE_A2017G_MODDED_MODEM_FOR_OREO_A2017V3.0.0B01-2_TURKDEVS
from this thread:
"https://forum.xda-developers.com/axon-7/development/anroid-8-official-mifavaor-ui-5-2-beta-t3707605"
But with this modem i have only 000000 instead of both IMEI, and after 1-2 there becomes no service on the sim 1(sim2 works but wifi calling works only on sim1) and after reflashing this modem it is good for 1-2 days.
I almost want to brake this phone because of such stupid bug.
Anyone use a2017u b20 firmware on a2017g? which modem do you use and do you have such problem.
Firs
replace the modem in the EDL package,with the G b03/b02 oreo modem.Then flash again the edl.Or flash the modem in twrp

hello, as i wrote before i tested b03 and b02 modems, flashed in twrp. On both there is a roblem with incoming calls from Iphone X.
Hello everyone.
Also tested on b12 by nfound. The same issue there on b12 g modem. I cant hear iphone X owners when receive calls from them. Hear them well when call them back. On Turkdevs modem incoming calls are ok, but no imei and "no service" after 1-2 days. I think i already tested all current roms. Maybe someone could mod b03 modem as turkdevs b01-02 from 1st post?
I got the same problem since yesterday. My device was away for a battery replacement some days ago. After I get it back everything was fine. Yesterday the modem stopped working. In my option I changed nothing. I just get no signal anymore. I'm still on 14.1 Nougat. I have tryed to flash the modem again, made a system, EFS, bootloader and twrp recovery but nothing worked so far. I also tryped to reset network settings and tryed another sim card..

I've actually never heard of this problem, so I'm not sure what the proper solution is. Going to stock via EDL has always fixed my problems in the past, so that's why I recommended it. You can give it a shot, it's not like your phone is very useful in it's current state as a "phone to call people with".

I already read something about it. Thanks for that advice again. It's the absolute wrong time for a error like this. I have absolute no time/no head for this.
My problem is totaly different.
Modem works. G modem (b12,b03,b02) works, but only one problem - incoming(outcoming good) call from iphone x is without sound - i cant hear them. But on one modem - b01-02 from turkdevs i can hear them, but there is no imei - 0000 instead of imei and after 1-2 days "no service"
I started this thread because i think that here could be a man, who could make some magic with b03 modem and make some changes, wich will allow me to hear iphone x users.
Your problem seems like it just wrong modem flashed. maybe some other to try and you will find some which will work.
Is there any user here, who could edit modem?
Hello, recently I bought and repaired an S8+ which is still in Nougat. Silly me not testing all basic function after the repair.
I hurriedly update the phone to Pie. Last night, i put in the simcard in slot 1 and it function well in 4g connection.
Here is the problem, whenever the phone disconnected from 4g and connecting to 3g/2g connection, there is notification "Sim 1 not allowed". After discovering that problem, i proceed testing sim 2 and its normal (can even toggle between 4g and 3g/2g).
I tried resetting the phone, but the problem persists.
Atm, i thinking of flashing stock rom, maybe something was corrupted during OTA update.
How can i fix this? Or anyone have an explanation to this problem.
Thanks!
