after flashing a custom rom like pixel experience rom my phone was unable to get signal and showing no service.
i have checked the imei they are still present in system info and did not went to zero.
please help.
This is a bug in just about every 8.1,,,I have had it and have tried all 8.1 roms. Some of the newer roms that have the updated camera blobs havent given me this problem. I am on Extended right now for the last few weeks and my signal has been strong so give that a try.
Anyone having volte issues, just flash magisk from https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 and reboot twice.

I decided to flash stock ROM again after having some camera issues on all Oreo ROMs. I have done this process many times and my PC is all set up to do a stock flash. This time after flashing stock rom for my UK g5 plus, I booted to no signal. After repeating the stock ROM flash a few times and, trying a few APN options and switching to 3g and back to 4g with nothing working, I realized there is a problem. After this, I tried going back to 8.1 pixel and Nitrogen, which did return my signal but, no 4g only 3g.
I'm a little confused as to what is going on here, no custom ROM flash can leave any effect after fastbooting stock to my knowledge. Any ideas?
How to
Credits @Castell93
Step by step:
1. Flash TWRP.
2. Flash Pixel Experience rom if we haven't flashed yet.
3. Turn on phone with flashed rom to obtain network signal
4. Here we will get the IMEI and only have 3g signal, so we need to restart the phone in bootloader mode and type in fastboot "fastboot erase modemst1" and "fastboot erase modemst2", these two command will give us IMEI and 4g signal.*
5. Turn on Pixel Experience again to obtain 4g(verify it pls), shutdown and enter Recovery mode (TWRP).
6. Do a backup of EFS and install stock rom.
7. Restore EFS backup and enjoy.
* NOTE: It's very important to turn on the phone once flashed Pixel Experience to obtain IMEI info and turn on again to obtain 4G.
This works to get 4g but volte no longer is working (used to be fine on nougat). I'm using TMobile usa

So, are you able to get back the 4G mobile data (4G LTE) at least?
Yes, I get LTE again, but not volte. Sad
Currently, all Oreo roms are causing this issue because they seem to update IMEI info and the modems. Once an Oreo rom has been flashed, there is no way to get voLTE back at the moment, however 4G can work again (with the method above).This issue will probably not be solved until the official Oreo rom is released by Motorola.

Hello, I know this thread is old. But I have a moto g5 xt1670 and it's been a week since I have lost 3g and 2g in my phone. I only have 4g. So I can't make nor receive calls. It is on stock Oreo 8.1. Going back to 7.0 stock didn't help. Neither Going to custom rom 9.0. don't know what else to do.

Trying using the QCOM option in the fastboot menu. Have been stuck on 3g since late 2017 and finally got it back by selecting that option which reboots me into the OS with working 4g regardless of what rom I flash. Don't know if it will work for you but try it and let me know.
Hello,
I've bought a LG v20 h910 2 months ago. 1 Month after I rooted it succefully, i tried some roms, and I chose lineage os 14.1. But I have a major issue now: my signal data was very weak and i figured my IMEI was = 0, so I tried to flash the stock kdz. I've done it, and I've flashed stock h910r rom. But my problem is still here: I have no IMEI and my phone is acting very strange : when I boot it with lg v20 stock, my SIM card is recognized and I write the pin, but the screen stays the same, I can't access my services even if it is the right code... I also tried others rom like lineage os 15, but I can't even access the configuration menus, I get a green screen with ram dump, even with stock boot...
Is a total reset possible, or could someone give me a full TWRP recovery?
Unfortunately no, that's the problem ... I also tried xposed imei changer, but it didn't worked... Is my phone dead doctor?
Edit: I flashed another stock kdz, and the phone works fine, the only problem is the sim card (again); are my imei number and this issue linked?
Edit 2: I followed this https://forum.xda-developers.com/v20/how-to/stock-att-h910-stock-recovery-boot-image-t3528060 , and now i have lte and sim detected, I think I am going to stay on this stock rom in order not to have other problems. But my imei is still 0, is this a real issue?
After several hours and dozens of applications and commands (erase modemst, qualcomm toolkit, qpst,...), I still have no solutions ... I have access to data, but it's very weak and it is only on stock rom, on lineage os 15 I want to keep, it's worst... Is there nobody who already had a problem like this? And would sharing an EFS partition could be possible on 2 different phones?
I know, It is my fault if I don't have IMEI, but I can't return my phone, the warranty was only 1 month long, and I really need 4g because of my poor internet...
Ok, sorry for the multipost, but I've finally found the solution: I tried xposed imei changer on stock rom and lineage os 14.1, but it didn't worked. I tried on lineage os 15.1, and worked like a charm ! I hope all my issues are gone and may this post help !
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:

Hi guys
i installed the oreo android 8.1 custom roms on my phone (A510FD) and because of too buggy experiences, i decided to back to stock firmware.
when i flashed the stock firmware via ODIN software, when my phone boots up, i faced with the big problem, the " NO SIM CARD DETECTED " Error message, and there is no signals, no imei and network related things.
flashed so many roms, customs and stocks, doesnt fix the problem.
finally i found an article about how to fixing imei problems for samsung phones, the answer is "Combination Roms".
after flashed the combination rom with due attention to my bootloader version (you must find a version that be equal or higher than your phone's bootloader's version), it fixed all problems. after that i flashed stock firmware and everything goes fine.
Combination Roms are made to fix and diagnosis phone, i'll hope it could help everyone that had the same problem .
Best regard

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.
