Phone has no LTE, yet still has imei, 3g data after flashing rom.

[L4ndon]

I have a G5S plus (xt1806) on sprint. Every rom I flash results in me not having LTE, and 3G cuts in and out unreliably. I have checked and my imei is still there. I have flashed the modems, and I have restored my efs backup to no avail. This has happened on every rom, no matter if I clean flash, dirty flash, I end up with the same result. Does anyone have any insight on this?

I had a similar issue on Verizon. When I got the phone I never inserted my new sim card & connected to the network before I unlocked the bl, flashed TWRP, custom ROM, etc. Every ROM I flashed had the same issue as you describe in your post.
Solution: I backed everything up to a pc & fastboot flashed back to stock & started over. Everything has been fine ever since.
***Keep that efs backup you made too - just in case you lose IMEI on your return to stock; efs restore should fix it.

Yea, I've tried reverting back to stock. I get back my service after restoring efs partition, but whenever I do it again, service is broken. I am at a loss.

Fwiw - I worked with another Sprint user a while back who could only get reliable service with the original firmware - that which came with the phone when purchased. Fortunately he had a bu of that and it was the only thing that worked. There is a thread about checking/fixing permissions on your persist partition that may help. Check it out - ya never know.

I really dislike how sprint deals with unlocked phones, they never play nice, I have had carrier specific issues with them in the past. If it wasn't for my grandfathered truly unlimited plan I would switch in a heartbeat.

And yea, I'll be sure to check that thread out, thanks!

I had the same problem. I made a thread about it and somebody gave the solution. See if it works for you. https://forum.xda-developers.com/moto-g5s-plus/help/4g-to-t3829195

I had initially had this in my previous reply - Sprint has always been special - but I deleted it, should have left it in. I've heard many bad stories from Sprint users in the past, going back years. Just glad I always stayed away from them (they have no coverage in my neck of the woods anyway).
Good luck!
PS - the link in the above post has the instructions to set correct permissions on affected files in persist partition - they came from the thread I mentioned.
