So last month, on my bill's due date (the 10th), my data (3G and 2G) completely shut off for almost a whole day (not voice, not SMS). Nothing would turn it back on, until it came back on its own. Now it's the 10th again and I've had no data all day. I am flashed over a Sanyo Incognito. So I try to call Boost and tell them the situation. They want me to call back from a different number because they insist that I exhaust every single option, as though I don't know how to troubleshoot my own phone. I call back from my phone again, and ask for a profile update (I have tried manually, it is impossible over wifi). She tells me she can't do anything, until I am talking to her on another phone. I ask her again nicely "can't you just force a profile update right now, or after I hang up?" she responds"...no, I can't".
So it looks like my only option is flashing a stock ROM, entering DIAG, and re-programming cellular data (I am not even sure this will fix it, the problem seems to be on their side). Any other thoughts, that could perhaps make my life easier? I would greatly appreciate it.
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.

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
Ladies and gentlemen of XDA, I have come before you today to admit to my defeat.
I have scoured the internet and tried all kinds of fixes and such and still no luck. So hopefully someone here can help me figure out what I'm missing.
I rooted both my husband's and my G955u. Both of our phones took the root well and were performing spectacularly. Then, randomly one day, something went glitchy with my phone. For some reason or another, I ended up putting the phone in airplane mode. For the life of me I can't remember why. The airplane mode icon would not turn back off. I turned the phone off and back on. Each time, I see the signal connection icon at the top, but there are no bars filling it. I cannot call, text, or use data unless I am connected to wifi.
I unrooted and flashed back to stock. No fix. I applied other root methods. Still no fix. Factory reset, cleared cache, took sim card out. Still nothing. Sim card works fine in other devices and no sim card will work in my phone. I have flashed each and every stock (2bqk5, 2bql1, 2brb1) with no luck. Took it all the way back down to 2bqk5 and allowed ota updates all the way to 2brb1. Still nothing.
Had an error for a while that when I entered recovery mode, it would either show no command or error followed by a screen saying that it had failed to unmount my EFS. That screen isn't showing up anymore, so I somehow fixed that. My IMEI and SN are both showing and are both correct. Phone network shows unknown. Mobile network shows state as connected. Mobile network type shows as IWLAN. Not Roaming, IMS registration status is on.
I have tried to flash the combined tar file of the modem and the Nonhlos.bin I extracted from my stock bql1 files. Flashed through Odin, still no fix.
I am at a total and complete loss. I don't know what else to try. Husband's root is still intact and working great. Can anyone help a noob figure out what I haven't done yet? I'm sure I'm missing something stupidly obvious. Any and all help is greatly appreciated and stories of your epicness will be told by my children's children of the time I was saved from the purgatory that is no cell service by the heroes of XDA.

Solved on my own. Downloaded the app shortcut master and launched secret menu #27663368378. Chose options 2,1,2,3,4 and restarted phone and I had network access again. Hooray!

Was just about to post about this, I too have been experiencing those issues, difference is my phone has not been rooted. Has the issue completely resolved?
Yes. That completely fixed my issues. You may not have to root to fix the issue if you can find the right secret code to access the service mode menu. But once the nv was restored, all was golden.
This is the screen you need to get to.
wow you went through all those downloads and flashes !
This was my first time ever rooting. I had no idea what I was doing or what exactly I needed to fix it I just knew I was pissed to high heaven and refusing to pay 200 for the replacement phone they said I needed.
Originally, geek squad tried to say that I had a chip failure due to the mipi device fail that showed up on menu *#0011#. But I didn't buy it. Turns out it wasn't a hardware issue. Just the NV data being a butt. Saved me 200 bucks. I'll take 50 million menus, flashes, and downloads over that anyway. That's what unlimited data and pdanet hotspot tether is for.
What did the menu have in it? I'm having a similar problem with not connecting to the network (unroot), but on my Galaxy S7. I've tried a million things, only to find out the "MIPI DEVICE FAILED".

I have the exact same issue on my S8+, MIPI device fail and can't get any network signal. On xfinity mobile here. I can't get that menu you're talking about, I downloaded Shortcut master and launch the menu you mentioned in your first post but it won't launch. Do I have to be rooted? Please help!
Mipi device failed. change the charging port and maybe it solves it. it has happened to me with a s7 and a note 8 and I have solved it by changing the loading port

I have the same issu on my G955U at&t variant. how did you solved the problem?
I'm having this issue in this model and the menu "*#27663368378# Chose options 2,1,2,3,4 and restarted phone" didn't solve, it will be necessary to change or reconnect the charging port or other part?
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.
