[Q] about verizon roaming message

Quick question,
I have had my phone rooted for several months now. Ever since I rooted though, I always got the "Verizon wireless can not authenticate your phone" message when roaming. This has not been a big deal until now.
I have already spent a lot of time with sprint support on the phone and at the store, and they actually are just giving me a new phone, so the problem is solved.
MY actual question is, are people still having this issue happen when they root their newer phones? I ask because I would like to root my new phone, but not sure if I want to chance it messing up my roaming again.

Yea, it happens, but you don't need a new phone as the fix is really easy.
Call Sprint support and have them reset your profile on their server. They will put you on hold for a minute while they do that. Then they will have you remove your battery for one minute (the tech gal I had actually timed it and told me when to put the battery back in). Then you will be good to go.
Note-I don't know why this is, but it took me about 15 minutes talking to convince the tech support gal to do it, but once she did it roaming works fine again.
You can download the "Roam Control" app from the market, which allows you to force roaming to check if it works, paid app, but it is cheap. I just told the tech support girl that their was a spot in my house behind a metal shed that I get roaming when I checked it (important because she wasn't willing to do anything unless I was currently in a roaming area, and I didn't think it was prudent to tell here I was using Roam control).

Well, they gave me a new MSID witch did not fix the issue. After about another 45 minutes of trying things, she transfered me to account services and they said that they would just replace the phone.
I do not roam very often at all, so I said okay.
I saved my nandroid backups and everything for if I re-root. I just wasnt sure if this was an issue people were still getting with their new phones or not.

[Q] Requesting Help With ( Possible? ) Lockscreen Issues

I've been trying ( seemingly unsuccessfully ) to troubleshoot an odd problem on my EVO that I was hoping to get some help on. Hoping somebody else has had a similar issue and found a fix because I'm pretty frustrated at this moment. Basically what I'm seeing it this : sometimes ( far too often ) but definitely not always, I have trouble either answering incoming calls and also interacting with texts through Handcent SMS. Given what happens I think they're related. On the calls issue what happens is that the phone rings and I try to slide down to answer but either the slider doesn't move at all or just moves a bit. As soon as the phone stops ringing I can then hit my power button, wait a second and then hit it again and then unlock just fine and I usually then call said person back. Similarly, sometimes when I get a pop up text message from Handcent I can't reply to it or close it, it's as if the screen is locked. Once again, if I hit my power button once and then again and then unlock I can close the message or reply to it. I've tried uninstalling all kinds of stuff like Beautiful Widgets, SetCPU and other such stuff thinking that a low level program or homescreen widget was causing the problem but that doesn't seem to have helped. The problem has now followed me from Azrael's ROM to Myn's ( which tells me it's likely not the ROMs ), so I'm guessing that it's either a configuration issue or possibly a program I have installed that's not playing nice for some reason. I've used Titanium to backup and restore between ROMs, perhaps that's part of the problem too, corruption? Other information that could be important...I have 002 hardware, I'm obviously rooted, and here's a link to my current stable of apps courtesy of AppBrain. If anybody can help I would greatly appreciate it!

Well it seems that the only constant between everything is Handcent. You mentioned uninstalling just about everything but that program. You should try uninstalling Handcent and seeing if your issue with answering calls goes away.

haa right? common sense..

Thanks for the suggestion. I have tried that, went to Chomp and the same thing happened to it! I've done a lot of reading and troubleshooting and one common theme was that Titanium Backup can cause such things as it can drag along corruption from ROM to ROM if you have it in any of your apps. Given this I finally put some serious work into this yesterday : I wiped everything but music and pics off of my SD card, re-flashed Myn's 2.2 RL4 ( after wiping data, cache and dalvik of course ), and then proceeded to manually install most of my apps off of the Market, some I just didn't bother with. Even after all of that it's still doing the same thing! Went to King CFS 11 kernal today as well. At this point I'm getting really frustrated, if anybody has any suggestions it would be very much appreciated!

I've done more reading today and found tons of similar reports from others, especially at AndroidForums...but really no real answers! The best I found were workarounds such as using a program called 'Easy Answer' I think. I can only imagine at this point that it's some odd combination of programs and how they deal with the builds I've tried. The last thing that I think has much hope is that I emailed the author of the program that I have to use due to low Sprint signal in my work building called 'Roam Control'. It basically allows you to 'force roam' as you used to be able to do on just about all phones but can't within native Android. Perhaps it doesn't get along with newer kernals or builds? It worked fine for me for several months on older stuff. Anyway, if anybody can think of anything or find anybody else that has come up with a solution because they're better searchers than me I sure would appreciate it!

I've worked in the IT business for many years, and troubleshooting step number 1 is usually to ask 'what's changed?'...I've tried to figure that out without much luck so far, but something just occurred to me, could the problem be deeper such as Baseband version or PRI version or something like that? It seems like I did upgrade all of those just a while back using a flashable file, my current values are as follows, perhaps they don't agree with my 0002 hardware which is why they were never offered to me automatically? Can't recall what I was on prior to that.
Baseband 2.15.00.09.01
PRI 1.77_003
PRL 60672

[Q] Phone freezes, looses connectivity

I cannot figure out a way to manage currently running apps more efficiently then the program already installed on the phone under "manage apps"
Basically the phone freezes and randomly drops signal. It is also running extremely slow and laggings even during simple txt messaging.
Any ideas

You need to be more specific, because right now the only thing more vague would be to say 'i have a phone'. But, seriously, we need to know if it's rooted, if so what ROM, any hacks or mods, and even what phone it is. This wouldn't be the first time someone posted in the wrong section.

I can see your point... I am more familiar with the inner workings of automotive forums then this forum.
The phone is a t-mobile my touch 3g slide.
It is using the stock t-mobile program... I hate it, I dont know how to change it
It is not rooted, overclocked or modded in any way.

Ahh, ok. I know of a couple things that could cause the phone to be laggy. One is if you have a lot of text messages, you'll want to delete them. The second would be to clear your cache. Over time, apps that use data, such as the browser, will build up cache. To clear it you go to menu > settings > applications > manage applications > and you'll be brought to a list of your apps. Now just go through and start selecting apps and see if they have any cache and if so clear it. It will look something like the attached image. You'll also free up storage as well. The way you get to it may be a little different as it's been a while since I've messed with stock. Worst case scenario would be to do a factory reset, but I don't think that's necessary and should only be used as a last resort.
Also, I don't know about the random freezing, but the signal loss could be due to the SIM card coming loose or dying. The "locking" SIM card tray sometimes has a tendency to work it's way loose.

What would you do?

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.
Do you BONSAI?

DDTM is not on is it??

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.

Note 4 Verizon no 4g and now lost 3g - in a strong 4g / 3g area

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.
