i flashed pixel experience rom and than tried to return to stock but i lost imei. so flashed again pixel and now i have 4g but volte is gone. Need help to get back to stock rom with VoLTE
There is no getting it back at this time. Warnings of this are all over the G5 plus forums.
We are very much screwed by Lenovorola over the LTE issue and no solution seems to be fixing the problem completely.
Is it possible to restore from some one else efs backup and change IMEI number through hex editor ?

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 everyone, I have a problem with my device, after installing 8 android and returning back was gone, I tried to restore it via persist sdes on the forum by the instructions like it turned out but then got the update over the air and it again became zero but the link worked decided to restore it via pixel but even on the pixel it was 0 can I return native firmware with normal imei sorry for my English
I have the same issue. On pixel room after all the instructions, but still no imei. Even after erasing modemst1/2 in bootloader.
I don't know why so many people are trying to restore IMEI with persist instructions. It is not meant to do that, and is only necessary for those who lost volte after getting back
service. If you do not have service and an IMEI of 0, adding the persist folder to your EFS will just further corrupt it. No where in the original instructions for using persist did it say to use it to fix IMEI 0.

So did you recover your imei in pixel experience rom?
u can recover u r imei in omni rom or pixel expirence
I have the moto g5 plus XT1686, I have installed pixel experience pie ROM, with IMEI 0. I have no back up of persist and EFS,
anyway, can I get signal and VoLTE, I had searched a lot but didn't find any solution
It now has latest twrp recovery for 910 and oreo, 91020i rooted rom. At this point it had 0 imei and modem files overwritten with something for another device. Found the modem files on reddit, a kind soul had linked his backups for 910, and got the imei back to what i have on the back on the phone. Still no signal but at least now finds the sim card and asks for pin. What else can cause no radio?
https://forum.xda-developers.com/t/lg-v20-h910-at-t-4g-band-issues.3771873/ according to this it's a hardware issue. Oh well I have 2 others, bit of a V20 freak because of the audio capabilities, so I may just get another $80 F800
All custom roms I tried crash at boot logo so no help there.
