SOLVED! - see post #7
This SM-N910V is rooted and had 3g but apparently I lost that when mucking around with things trying to get 4g. I've got other phones like a Galaxy S5 and Galaxy Note 5 both Verizon models that get 4g or 3g fine in this same location.
First odd thing I noticed on the Note 4 was a setting that popped up seemingly by itself while in 'More Networks' and 'Mobile Networks' that showed VZWInternet with a circle by that which was not yet checked so I tapped that and it turned green in the circle. I have never been able to see that option again. I don't think this caused the problem though. I've looked at apns-conf.xml in the /system/etc folder and can't see a problem there. I also tried replacing that with another one that is supposed to fix LTE mode. No luck so I put back the original. I wiped cache and reflashed a backup with TWRP which had been working on 3G but that didn't help - no 3g even. I did not wipe Dalvik/ART cache. I had been messing around in the 'Service Mode' menu with a bunch of different settings in an attempt to get 4g working but I'm fairly certain I got everything set back the way it was before I started. I noticed that one setting I had left different in the Service menu did not change back after flashing a restore with TWRP (full restore - all boxes checked). The one setting I left changed was the under the 'AS' protocol menu where I changed the Release version control to "LTE 3GPP REL 9" from LTE 3GPP REL 10". I know enough to be dangerous
Open to any suggestions - am wondering at the moment if I should have wiped the Dalvik/ART cache before the whole TWRP restore? At this point I'd be happy just to get 3g working again.
I also tried Dr. Ketan's LTE Enable. That didn't fix anything. Although I see MNC and MCC numbers in the apns-conf.xml file when I look at the SIM with a SIM info App I just see blanks in those spots on the SIM. Not sure if that's relevant - just giving as much info as I can here.
Did another restore with TWRP after wiping Dalvik/ART cache but that didn't fix it either. Strong cell signal but no 3G or 4G.
More info - I put the SIM card in another phone and it sees 3G at least.
It seems the "lost 3g or 4g" problem is very common and it seems I've looked through dozens of message threads here but I'm not finding any solutions. I'm looking at flashing the 'ltefix.zip' from this thread but it seemed to be for a custom ROM and I've just got the stock - more or less - 5.1.1.
Hmmm.... Been at this all day reading here, searching, trying everything but still no Mobile Data. Is this as elusive as rooting a Verizon Note 5? LOL - it was working at least on 3G. I'll take hints or even wild guesses at this point.
Okay - it finally flashed on me to do a restore of my EFS. Oddly I had done a full restore with TWRP which include EFS but that didn't fix the problem. That TWRP backup was done the same day I did an EFS backup using Dr. Ketan's IMEI tool for the Note 4. When I used the IMEI tool to restore the EFS backup I then had the 3G come back on. This is a 4G SIM so I still don't know why I'm not getting 4G but at least I got 3G back. I did have a hiccup using this IMEI tool which initially caused the phone to repeatedly shutdown after a minute or so and could not be restarted without pulling the battery. I believe it had to do with the 'Restore' button needing to be held down a certain amount of time instead of just a tap. I probably held, released too soon then held longer which I suspect caused a partial or damaged EFS restore. Be careful in how you use this tool or you may end up in that situation. I had to work very fast after a bootup to get it properly restored. After that it was stable again and had 3G.
Now if only I could figure out what it takes to get 4G.
..
I wasn't getting 4G for the longest time, checked the PRL in settings on my GFs phone and noticed my PRL ver was like 50 thousand something while hers was 15518. Got a new Sim card and all my issues went away, PSA do not use *228 programming...EVER.

Update/more info - I've continued to try and figure this out to no avail, although I got fed up with stock unrooted 5.1 and am now running modestrom v9 with a CQI2 base. And all of that install went fine, except for 4g of course.
I think this is worth mentioning as it might have something to do with the situation:
Way back in the beginning, I had gone through the entire unlock/root process, and everything actually worked fine the first time. This was right about the time the unlock became available, I bought the phone based specifically on that being possible, and got a brand new one at that time. Well, it was awesome for about 2 weeks, fully functional 4g and everything.
I had a very particular goal - I wanted this phone totally unlocked, but I was also very interested in the advanced/wifi calling that was supposedly coming out at that time - I was planning to move to a place with no vzw service and would be reliant on wifi for calls at home. Verizon wasn't clear about the fact that the wifi calling feature wasn't coming until MM, and this was before MM was released, so I was running a completely functional, 5.1.1 rom. I believe it was jasmine. So, under the impression that "advanced calling" would have given me wifi calling, I tried to enable it.
I cant recall if it was immediately, or a few hours after, but this is when the phone lost 4g for the first time. I immediately tried to deactivate the advanced calling feature on my line, but it didn't help. And nothing I could do would bring back 4g. I tried everything possible, and ultimately gave up and threw the phone in a drawer and went back to my note 3.
Fast forward several months, and my note 3 began to have issues with call audio, forcing me to use the 3g-only note 4 in order to actually handle day to day business. Again, I went through the processes of trying to fix 4g, with no success. Now by this time, MM had been released, I believe PD1 was the current firmware. I figured at this point it was time to just odin back to 5.1.1 and start everything over.
So I odin flashed the phone, and it booted into 5.1.1......with no 4g. Again I went through all the things I found here, no improvement. Finally, one day when the phone was bugging me about an OTA, I figured "what can it hurt at this point, its nearly useless without 4g anyhow."
And low and behold, the OTA update from verizon booted up and immediately jumped to 4g.
Now I felt I had a chance, a method that I'd finally proven could fix the problem. I left the phone in that state for a couple weeks, just to prove that it was holding. No problems during this time.
But I got sick of no root, and so I figured it was time to try and go through the steps again. And again, I lost the 4g connection. No big deal, just odin back to 5.1.1 and let it OTA like last time......
Except this time it didn't work. So I odin flashed back to 5.1 again, and let it try to OTA, again. I let the phone continually try to OTA all the way up to current, and flashed back to 5.1 at least 3 times to repeat the process in hopes it might fix something. No change at all. At this point I actually began to try and see if possibly Kies could help me here - maybe there was something related to the phones EFS? Which I don't understand very well btw - it was only through reading this thread that I began to research EFS and its significance. I also attempted to use some of the checkboxes in odin - the ones to erase all NAND and to clear EFS and rebuild it. Neither option made any difference. So I figured next logical step was to start playing around in service mode, which would require unlocking/rooting again......
And thats how I landed here. About an hour ago I got sick of the stock 5.1.1 and went through the whole root/unlock process and I'm currently running modestrom on CQI2 or whatever was just most recently posted. Every other part of the phone seems normal, but still no 4g. I can actually see the radio making an attempt to connect in the service mode - but I don't understand service mode menus well enough to interpret where the actual problem is. Upon boot the phone tries about 3 or 4 times to get an lte signal, during this time there is simply bars of signal, NO data indicator of any kind. Eventually, it gets frustrated and gives up, connecting to 3g and staying there. I realize now that when 3g drops, which is roughly every 10 minutes or so, its actually the phone attempting to establish LTE again. But still, I cannot make any sense of this.
Apologies for the giant post - I'm trying to put anything that could possibly be relevant info into one place here.
So........ anyone got any suggestions?

PM sent. Just to share a little of that here I think the first thing I would do is tell VZ you suspect your SIM card is bad and have them put in another one. Tell them it fell out when changing a battery, the dog ate it and by the time it came out you suspect it wasn't quite right anymore - LOL. I do think SIM's flake out sometimes and I know a bad one can prevent 4G from working. If you ever had an EFS backup from anything try restoring ONLY the EFS (if you use TWRP). No guarantees that will fix it but my best guesses at this point. Good luck.

I supect Verizon's doing this ...

I got a used stock note 4 to try and compare and see what I could be missing here....
Tried new sim card at least twice, unfortunately no dice, and the same card pops right into the spare note 4 and it wakes up on 4g just fine.......
EFS is something I probably should have been quick enough to dig in deeper on before this, as I don't have any backup of it....... however, I'm not seeing any other symptoms, I can see my imei fine, and every other function works. Is it possible that corrupted EFS can cause the loss of just one type of connection like that?
For giggles I tried a friends att sim, and no lte on that either.
Playing with the app LTE discovery, I can tell that the phone sees 4 different LTE towers just fine, showing db numbers exactly in line with the stock note 4 sitting right next to it, theres just something there under the surface thats stopping them from hooking up...... it stops trying after a couple minutes, rejects them all and connects to 3g.
I'm convinced its some kind of software thing, but I can't tell exactly where the failure is happening.....
I also odin flashed it back to stock bpa1, and still no dice. Is there a means to make an EFS backup without root? I want to see what happens if I try unlocking the other note 4 as well, but this time I want to have the backups......

I've been running on Emotion 7.1.1 for months with NO issues (well, some minor stuff, you know....)
Suddenly, two weeks ago I got a notice from Google that I had to sign in on my phone. Verrrryyy odd. At first I suspected some hack attempt, but my Account checked out fine. Having changed my password recently, I had to wait until I got home to login.
After I logged in, all ~appeared~ to be OK. Then I opened my Calendar. B L A N K. All ten years of appointments gone. I freaked out. I have two calendars, one for personal stuff, birthdays and the like, and another with my business appointments, INCLUDING FINANCIAL STATUS of the account. Gone.
Went online on my PC, signed into Gmail and switched to my calendar. Empty. Looked in Trash. Nothing. Vanished. Nada. Niet. There's a long story here about recovery efforts, troubleshooting, Googling, etc, suffice to say that TWO separate, redundant, backups had quietly failed, without the notifications they were supposed to send. I did manage to get from the first week in April back 10 years, but lost the whole summer. Thank YOU-KNOW-WHO that I'm good friends with all my clients.
Fast forward to last week. Suddenly I get 3G only from my Verizon account. Like you, I spent days on the boards, downloading ROMS, wiping, re-wiping, trying everything short of smoke signals to get it back. No joy. I did NOT go back to stock, I must thank you greatly, as that was my next road. Now i see it's a dead end. I will NOT give up my Nougat root just to get 4G.
Perhaps this is a bit conspiracy theory sounding, but I've become convinced that Verizon is playing some game, perhaps to force us to upgrade to a new phone. I learned long ago that corporations have no soul, and will do anything they like to increase profits. They exist for two reasons; to make money for their officers and to make money for their stockholders. Any other semblance of a "Product" or "Service" exist ONLY and SOLELY for that reason. Anyone who is a Yahoo or AOL member knows the level of intrusive ads and attempts to trick people into putting spyware in their machines under the guise of "protection" or "cleanup" programs has jumped to a new level of absurdity since Verizon sucked them up. "Oath" indeed. It's what is coming out of existing customer's mouths! M O N E Y H U N G R Y.
When I chatted at length with a Verizon Tech, she made it clear that she knew the answer was to upgrade to the latest stock (I never admitted to rooting, but she knew, we spoke "between the lines" a lot). She sent me a SIM card, but it., of course, didn't fix the problem, in fact it would not even initialize properly! I had to go back to the original SIM.
Now that we've found a way (after YEARS of trying) around their stupid block on rooting, they change the game. What person who is so into their phone as to root it, will put up with 3G? This is something Verizon is playing at, Sprint too from what I gather.
My only consolation is that I've got so many WiFi's nearly everywhere I go, and when I'm not near one, my Wife's Note 4 (not rooted, on latest update) works fine. I'm glad I decided not to root hers too.
Frankly, this really ticks me off. I have better things to do than spend days copying files, flashing and reloading data. Verizon knows that, and let me tell you, it won't be THEM who sees my money when I finally do upgrade.
Thanks again for saving me from the Stock route, you saved me hours of grief.
Peace out!

I have run into 4g issues with this as well and almost came to conclusion is a modem issue. I want to say but can not confirm that modems that are flashed are relative to bootloader on the device. Just something I've been pondering on as I had a unlocked bootloader device and flashed for wife to use with no root and recently unlocked again.

Over the past 2 weeks, I have tried to research the answers to my questions, but could barely find anything on this particular subject. So it's my first time posting to this forum, and my situation is a little embarrassing. I have had my htc evo for about 1 1/2 years, and I finally decided to root it 2 weeks ago. I've been with sprint for 6 years, and am on the unlimited data family plan, as well as the sprint hotspot feature on my phone, which I pay them 30 dollars additionally every month. I pretty much exclusively use my phone for all tasks and browsing and downloading etc, so I didn't get this feature for the "wireless tethering" , I actually got it so I could discontinue my home wireless internet through cox communications, so my phone is my only wifi source at home. I almost never use an actual pc!
I rooted my evo for 2 reasons mainly: 1) I am sort of an app addict, and I needed to free some space on my phone. I especially love using different keyboards ( which are often very large files). 2) I love customizing my home screens, but want to be able to use icons from icon packs such as crazy home's, with ADW launcher etc. I did a factory data reset on my phone before rooting, and I think I backed up all my apps to my laptop... but I wanted to start fresh anyway, so have not bothered to restore them from my pc to my phone.
Two days before I rooted my phone, Sprint temporarily disconnected my account do to Past due payment. I'm not going to get into the details, But I can't afford to pay off my balance until May. It is what it is, I'm not whining or complaining, times are a little tough for me financially and i just have to deal with not being able to make calls or text for a month. Lol, it's harder than I thought! It's pathetic how dependent my family has become on cell phones and texting for communication. We don't even have a land line. Just to give you a quick background, I didn't even know what sd card was, or a usb cable, before I got my htc evo. I'm not tech savvy at all, But when I first learned what this phone could do I was hooked. I have a laptop at home, But I never use it because a few keys on the keyboard are broken. As a matter of fact, The first time I actually plugged my phone into my pc, was when I rooted it!. I used the unrevoked 3 method, which was fairly straightforward. Because I have no data access right now, I was unable to update my profile etc. And of course, without data access I cannot take advantage of the free wireless tether.
My main question is, did I make a mistake in rooting my phone while not having network access? Right now, if I'm not in a wifi area I basically can't do much with my phone. I downloaded a few apps that allow free calling over a wireless connection, and facebook chat,etc... so I can communicate with my family as long as I'm in a wifi zone. But, I have been afraid to do anything else with my phone because I wanted to do a little research on this. I know some of you are probably thinking, why didn't she research it before she rooted? Lol, I would be saying the same thing! I didn't even think about it until I was done routing and it told me to update my profile. Since then I've been a little freaked. I'm hoping I didn't Make a bad choice. I just wanted to the able to access a few icon packs lol.
Is there anything I should know, or have done differently? Or does it make no difference at all? I guess basically what I'm getting at, is can I go ahead and reset my phone again and start flashing roms, just like I would if I had network access?
Again, please forgive me if I sound ignorant in this matter... because I am. Any advice will be much appreciated.
You can start flashing roms as normal. You didn't make a bad choice rooting without data access, because whether you do or don't doesn't make a different. i would say just make a back up of your apps in titanium backup, then backup your rom before flashing.
And you can pm me if you need any help.
Post neglected...double post.
I would say to reflash ur rom but it might not work try to go back to the sense rom if u have it backed up once u do that update everything under ur settings nd updates nd if it still don't work the only other thing I know u can do is unroot it and take it to.sprint so thay can look it

Not being able to update the profile won't make any difference at all, if you have no data connection to begin with. Once you're able to get things situated, and you need to get your phone activated again, you'll just need to make sure you're on a Sense rom before you activate it again. No worries, you can flash away all you want, with or without a data connection.
Also, how have you had your Evo for 1 1/2 years!? They were released June 4th last year!
Ha ha really? I feel like I've had this evo for years.. since the day I got it I've been like a kid in a candy store! Thanks for the reassurance everyone. Unfortunately, I've just encountered the problem with the SD card not being recognized by my phone or my PC. According to my research, I'm supposed to find this file on my SD card under android. secure and delete it? But my PC isn't recognizing my card, and my apps that are on SD are seen by my phone. I get a force close when attempting to unmount SD. My market apps won't install or uninstall.... ugh. Like an idiot,I never did a Nandroid backup. I really don't care about losing my app backups though,I just don't want to mess up my phone. All this information is overwhelming me... Nandroid this, titanium that, recovery boot, drivers, and on and on.... so much advice is outdated I don't know which to follow. I'm a dummy! That's why I need my smartphone to help me out lol.... how do I fix this?
Eek....I just saw a gigantic spider.... creepy..
in a nutshell, you can do anything with your phone, without data access, or service.
I rooted and flashed the ROM I did for my old Moment, after it had been turned off so I could sell it.
Now that you are rooted, I uses Titanium backup for all my apps/data. I only backup actually apps, not HTC stuff, etc, or anything that comes with the ROM you flash.
You can tell this becasue the apps are in white lettering in the Backup menu.
At least they are on mine, and I use all default settings.
rooted without data access
Thanks everyone...I fixed my problem with my sd card, turns out mine had gotten corrupted so I will deal with that later.I just put in my other card and Im back in business....lost all my personal info though. Thats the least of my worries. Someone said I can do anything on my phone without data service, but they must mean only when I am in Wifi zone right ? See, unfortunately, I dont live in a populated area. I have no wifi access at home and there are hardly any free wifi spots in town. At home, I can see that there are wifi networks around (linkys via cox communications), but they are locked. Oh, thats another question i had....why do people lock their wifi? I never did, and I have no problem letting others access mine when they need it. Should I? If so, why?I am so sorry if I sound clueless again, but Im learning a little more every day thanks to people like you!
So as far as communication, Im out of luck. A couple months ago,I had an issue connecting to the network while i was at home, but i just turned on my sprint hotspot and i had instant network access so i couldnt call or text, but i was able to get a hold of my daughter on facebook lol. How did my phone do that? I dont get it. I am going to a couple of those prepaid phones tomorrow so we can make calls in the meantime.
As far as navigation, any tips on how to find any apps that dont need network access that work well? I found a couple, but they seem so complicated to set up. And, I tried Nettalk for making calls over wifi but it only works sometimes. I read about apps that offer free sms and calls over wifi but I couldnt find one that was stable.
I cant wait to get my service restored..I didnt realize how much I depended on it. I still havent flashed any ROMS...Im a little nervous. I still dont totally understand what is different about my evo now tthat its rooted, but i plan to educate myself once I get full access to wifi again.
Any advice/tips is very much appreciated. Thanks again for this useful forum.
Ok guys, been a long battle. I spent a combined four and a half hours on the phone with sprint yesterday morning. We did soft resets, hard resets. We checked ESN and other numbers I didn't know existed. We checked towers as well.
And after all this, I still have issues making calls. When I go to make a call at home, it automatically disconnects even though I have full bars and my data is working. I also cannot receive calls, as everyone texts me saying that it is going straight to voice mail. I only really go three places.(work, home, gf's place) The problem occurs at both my place and work. However, it doesn't seem to happen when I am on the road, and it only happens sometimes at my gf's.
I took the phone to Sprint with a ticket number given to me by a second tier manager? The sprint store rebooted my phone a few times, tried to make a few calls. Of course it works. So their rule is, if they cannot replicate the problem, they cannot help.
So I guess I am asking what you guys would do. The only two option I see are:
1. Buy a used EVO and finish out my contract(14months) hoping nothing goes wrong with it.
2. Take the early penalty, close my account and go to Verizon like the rest of my friends whose GPS's and calling "just work".
I would hate to leave sprint cause they have the best unlimited deal out there. But this is the second "top of the line" phone I have bought with them that has been a disaster. And both of them seemed to work flawlessly for the first couple months I had them.
By the way, I am on stock EC05, and I have been ever since it EC05 came out. I am not rooted or anything. It was working fine till about Friday.
Do you have TEP?
Wow, try taking out the sd card and use the phone to make a call. SD cards can make the phone do some funky things. If that works; then put it back in, connect the phone to your computer, copy all the contents to your computer; format the sd card and copy the contents back to the sd card.
change to sprint only network (settings - wireless networks - mobile networks - system select .. choose sprint only)
uninstall app 3rd party applications; perhaps something running is the culprit
If still no joy; I would root it and try a custom ROM. Maybe a file got corrupted at some point and that is causing the disconnections.
I really like the one I am on, its worked beautifully.
I'd be happy to help you through the root process if it gets to that point.
Good luck
It doesn't matter whether I have it or not, they rebooted the phone, brought up the dialer, made one call(he might have made two, one of the other people was talking to me) and sent me on my way. If they can't replicate the problem, then their policy is to not do anything. I even asked them if I could make a video of it first hand when I get home, and they basically said that won't change anything cause they have to be able to replicate the problem first hand.

I will try SD card when I get home. I don't have any third party apps, as the technician on the phone hard reset my phone like 3 times. I tried every custom rom, and I even tried to go back to DI18. All of them had the same problem, so I am guessing it is hardware related. Again, data is working correctly, just seems to be something with the calling hardware.

If you have TEP - don't even bother with taking to the store any longer. Just complain enough over the phone and you should be able to get someone to send you a new one.

Unfortunately I cannot really wait for them to send me a phone. I need to get something today, as this phone is also my work phone. Customers do not like going straight to my voicemail :/
After a tech on the phone with Sprint screwed my phone up even worse, had me stuck in an activation loop. He told me to bring it to a Sprint store. Well this was at night so I Odin'd to stock DI18 and let it do the OTA and that cleared up the loop. It may work for you and save you grief.

I've heard of similar things. I helped someone troubleshoot the problem and came up with it had to be the tower. They called again to customer service and of course they said that nothing is wrong with the tower. I think that they called again to make a report to check out the tower near their house. They did that a few times. I don't know how long it took to fix the situation. I do notice lately that, even though signal strength was okay before, it's better now.
If you have another sprint phone, if you activate it, does it do the same thing? This might be one of those instances that if you complain enough, maybe they might give you one of those devices they have (I forgot what it's called) that you hook up to your home internet and it acts like a mini tower at home. I've heard of stories that after enough complaining enough, they'll just give you one. If the phone still does it then it's the phone that's flaky.
When you talk to someone, make it clear you use this phone for work and if people can't reach you, you will lose clients. If you start losing clients because of this then you will be forced to go to another carrier. If they say you'll have to pay etf then tell them you won't because it isn't your fault that you can't make or receive calls at work and home.
This phone or their equipment or service isn't working properly and you're losing customers because of this.
Here's another idea. Find someone else that has sprint. Have them go by your work and home and see if they can send or receive calls. If they can then its your phone, if they can't then it's the towers.

I will try SD card when I get home. I don't have any third party apps, as the technician on the phone hard reset my phone like 3 times. I tried every custom rom, and I even tried to go back to DI18. All of them had the same problem, so I am guessing it is hardware related. Again, data is working correctly, just seems to be something with the calling hardware.

Man, I'd be flippin out if it were me. That has got to SUCK!!
Recently purchased a new, unlocked S8+ and got a new SIM from Verizon. This was approximately 2 weeks ago. Zero problems up until this week. I have been on 4 flights this week - before each flight, the phone works great. When I land on the other end, Verizon LTE pops right up, varying numbers of bars as one would expect depending on arrival airport, just like it would normally when I have service and can do everything. However, nothing. No texts, no calling, no data. Tried toggling various things, resetting, nothing for a hour after that, all the while I've got 3-4-5 bars and I can see the data arrows lighting up like there is upload/download transfer.
Finally, I tried "reset network settings" as a last resort and immediately my phone works like a charm. It has happened another 3 times since - every time I have flown, with the exact same results.
All domestic flights. While I'm not a guru, I'm not a complete halfwit either - this is my 4th galaxy and it's definitely not something I'm doing or have ever had problems with before. I fly all the time and never a problem like this until this week. Checked APN, it's right. Checked software update - have most recent.
Any ideas? I'm desperate. Have searched literally everything I can think of and no one else seems to be reporting this problem, not to mention it's difficult to describe in a Google search. About at my wit's end having to re-enter wifi and passwords every day, relearn Bluetooth devices. Theres no other way to truly reset the mobile data settings and get my phone to work that I've discovered. Please, please help.
Eject SD card and remove sim, wait a min, reinsert cards. While the phone is on. Should reset just ur sim settings. Maybe
I apologize in advance for the long read.
I recently activated Verizon service on a Note 4 that has been sitting unused since the Note 8 came out. The Note 4 is in perfect physical condition, with no scratches on the screen or body, and has been in a protective case since new. I did replace the battery in it prior to activation, as I expect for the life to have been deteriorated.
I did a factory reset and inserted my Verizon SIM card, and it worked perfectly. I installed my everyday apps and a few games on the phone, and I used it without any issue for about a week. During that time, it did install a couple of OTA updates, but I expected that since it had been "off service" for a few years.
After that first week, I put the SIM card back in my NOTE 8 for a couple of days, after which I went back to the Note 4. Initially, 4G data and cell service worked, but within the same day I started having service drops. If I was on the phone and a call dropped, it would show an error message saying "No SIM / SIM Error".
Her is what I have attempted so far:
First, I replaced the SIM with a new one. There was difference in the frequency of the random service drop.
When that did nothing, I assumed that one of the OTA updates from the prior week had done something to modem / radio. The phone was on 6.0.1 at that time. I unlocked the bootloader and installed TWRP, and first tried downgrading to stock 5.1.1, then to a "modified 5.1.1, then to CM 13, and now Lineage 15 (frequently factory reset / cache wipe. There has not been an improvement (or reduction) to the random service drop.
Yesterday, I happened to be on My Verizon online, and I had a message showing that Verizon no long had the information on my phone (IMEI), and requesting that I open a Chat Window to update my info. At this point, the Note 4 is still running the Lineage 15.1. The Verizon team member asked me for the IMEI, and when I looked under the settings, it said "None" under IMEI. In a quick search, I found a forum on Lineage 15.1 that said turning of the screen lock and rebooting the phone will reload the SIM and IMEI info. That worked, and I was able to view the IMEI and verify connection. I explained my issue with the Verizon support, and she said everything appeared to be good on her end. Over the course of 15 minutes, we tested my connection and it worked. About 30 minutes after that, it dropped service again.
Finally, here is where it is at now:
I start with no service. If I do nothing but restart the phone, it will show LTE service for 2 or 3 seconds, then nothing. If I remove and reinstall the SIM, I will get the same 2 or 3 seconds, then nothing. If I turn Airplane Mode on and off, that does not reconnect the service. If I change the lock screen security to "None" and restart the phone, there is no service, but if I set Screen Lock to "Swipe" and restart the phone, I will have LTE service for at least 30 - 45 minutes before it drops, sometimes a few hours. When it does drop, it does not come back on it's own. The only way I have found to get it back it to "Screen Lock - None, reboot, Screen Lock - swipe, reboot".
Will replacing the modem fix the problem? Is there a specific modem that I need to match up to the ROM? Thanks!

I think you might be dealing with 2 separate issues. I'm kind of guessing about the first issue but the second is a common problem.
I think the original problem is that your sim card is not making a good contact in the sim slot. You could try putting a think piece of cardboard or something that will press the sim card to the sim slot contacts (maybe check to make sure that there isn't any dirt on the contacts but from the sound of it I'm guessing your phone is pretty clean).
The second problem is that all of the aosp roms have varying degrees of signal loss that occurs. Some people have a lot and some not as much, but everyone is affected in some way with what people have been referring to as "sim death".
My suggestion would be to run a stock or modified stock rom until you get your sim problem straightened out and then if you still want to switch to an aosp rom then at least you'll know that any further problems are just the normal sim death that occurs from time to time with those types of roms.
If you've already updated your bootloader to a 6.0.1 version you can flash the modified stock rom that I put together. I haven't had any signal/sim issues at all with that and no reports of it. Like I mentioned before though, the only caveat is that it needs to be on a bootloader that is at least CPD1 or newer. If it's not then your wifi won't work.

Thank you for the reply. I think that you may be onto something with both issues. After posting this question today, I did examine the SIM slot, and although all of the pins looked good, and no dust or debris was visible, the metal guide over the SIM did feel slightly loose from the card. I did put in a thin shim, and the significantly improved the time that the phone stays connected. If that was a true issue, along with the possibility of the ROM causing a separate cause, I am absolutely interested on going back to a stock (or modified stock) ROM. The only reason that I did what I did was an attempt to fix the connectivity issue.
Thanks for your help. I will give your ROM a try and let you know how it works.
TL;DR
Moto Z2 Play - XT1710-07
The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
