I was using Bootleggers (8.1 Oreo ) ROM on my XT1686 and tried flashing Pixel experience (9.0 pie ).
Steps i went through:
1. Clean Wipe
2. Flashing Pixel Experience
3. Losing my network signals and IMEI
4. TWRP flashable 8.1 stock rom
5. Flashing the bootleggers 9.0pie update
6. Trying the erasemodemst 1/2 commands. NO result.
6. Restoring EFS and persist from the previous backup.
7. Ended up having IMEI back but still no network signals after multiple reboots.

I do know that flashing a STOCK ROM using fastboot and performing a clean reset will get my network back but will i have to stay back in the STOCK ROM ? Can nothing be done that allows me to keep using this amazing rom with a functioning network ?


TL;DR: NO NETWORK, IMEI AVAILABLE. EFS AND PERSIST BACKUPS ARE FLASHED ALREADY.

You didn't say from what ROM/firmware the persist.img backup was taken. If it wasn't from your original stock firmware that may be a problem. If it was from stock which version, 7.0 or 8.1?
If you flash a 8.1 signed fastboot firmware you should be able to change to every ROM you want to afterwards.

I lost the IMEI and VoLTE when i switched from 7.0 (stock) to 8.1 (experience ) rom and then had to use the VoLTE fix to set it straight.
After i got everything working in my 8.1 pixel experience ROM , i made a backup of all the partitions. I used that backup here.

Most probably the problem was to switch from 7.0 stock to a custom ROM, you should have updated to stock 8.1 and make a backup of persist before doing that. The persist.img will be modified when flashing a custom ROM.
If you haven't flashed someone else's persist file the best way to go would be flashing a signed Motorola 8.1 firmware by fastboot, take a full nandroid incl. persist and go from there to a custom ROM.
Here's how to do it and links to all available firmwares:

Thanks alot @Wolfcity. Sorry i couldnt reply sooner. I flashed a twpr flashable 8.0 stock by @NZpred from the page here:
https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-fastboot-flash-stock-oreo-t3848433

It brought back the signals. After that i backed up all the files and EFS and reflashed the custom rom and the EFS and persist.

Thanks alot for your help and timely response.
