[q] major screw up. Helpppp!!!

So I originally rooted my S3 using odin and a stock verizon software followed by using ez bootload unlock, ez recovery, and clockwork mod. I used the custom rom cyanogen mod, and eventually continued to update those roms when they rolled out the OTA updates. When the latest update came out on the 18th I noticed an issue with my contacts. Due to this I reverted to the 16th rom, but something went terribly wrong. At this time I tried re-rooting, tried different types of rooting and got my device working along with my contacts back, but it rendered my sim card useless. I tried everything I could find on the internet. I finally covered my tracks and took it to the verizon store. They replace the sim card, but it still didn't work. They replaced my device, and me being dumb I rooted it again. Same original rooting that worked the first time. It worked at first, but then the same issue occurred. I'm not sure what to do, I can't go back to verizon again. They will expect something this time. It makes no sense. The hardware is not an issue, there is some data error somewhere. PLEASE HELP!!!
TLDR; Crazy weird data issue maybe? Whoever can solve this will be the House of Android rooting.

Why don't you try to Odin a pre-rooted Verizon stock can be found here http://forum.xda-developers.com/showthread.php?t=1984436 to see if it addressed both our your issues?

I just had some major issues with this as well. There is something wrong with the nightly versions of CM 10.1.
Like you - I flashed CM 10.1 12/18 and found that my data was not working. I then searched this forum and found that other users were having the no data issue as well. I decided that I would do the same and flash back to an earlier CM 10 release from December, but the update did not go as expected. Due to going 10.1 to 10 I had to wipe data/cache/dalvik. At this point I got CM 10 reinstalled, but the phone came up with NO cell coverage. I went to System Settings -> About -> Status and found that the phone was no longer registering my cellular network (Verizon) or phone number. My IMEI data was dead.
Luckily in my case I had already made backups of my IMEI data per this post: http://forum.xda-developers.com/showthread.php?t=1852255
I restored my IMEI and reflashed CM 10 12/16. Everything is now working as expected. Your issue sounds identical to mine - I just spent half the day fighting with the exact same issue. I definitely learned my lesson about staying so current with the NIGHTLY builds for day-to-day non-dev use. I knew it before, it just never bit me like this.
Anyways, I hope this information helps you somewhat. Good luck!

You most likely lost you imei/min or something, you can check in settings>about phone>status. Easy way to correct it is to flash a older stock ICS image and use the reprovision code. Flash this in odin then type this in the dialer *2767*3855# and that should fix ya back up. Flashing anything carries a risk of dropping your imei but it happens much more on AOSP roms.

[Q] SMS won't send. Can receive/send MMS calls and Data

The Problem/Symptoms: I've been running a version of last CM10.2 for the past year. On February 20th, I was able to send a single SMS and then subsequent texts failed. I could still receive SMS, send/receive MMS, send/receive calls and send/receive data. If I toggle airplane mode/reboot I can send another SMS and then subsequent sms are undeliverable.
What wont work: Flashing to CM11 does not change the issue.
Disabling Voice+ does not change the issue
Factory Reset does not change the issue
Workarounds: Toggle Airplane mode
Switching Mobile Network to CDMA only (not permanent)
Change your number to a different area code
Going back to a Touchwiz based ROM
The Solution
net-cat said:
Alright. I think I've refined my process and it results in having a newer radio as well as not having to ODIN things or do dd commands.
NOTE: This isn't fully tested. When I did this, my phone wasn't showing the issue. I did this after doing my original procedure, but the GPS stopped working after I updated the radio from VRALF2 to VRBMB1. You shouldn't need to do the original procedure for this to work, but I haven't tested that. At the very least, the original procedure still works and this one can be used afterward if you need the newer radio. (GSM support...)
Ideally, we'll want to get to a procedure that doesn't use ODIN or dd. Hopefully this is a step in that direction.
Requirements:
A rooted stock ROM of the VRUCML1/4.3 vintage. I used Scott's Stock Rooted Knox Free VRUCML1 - 4.3 - DeOdex - V2. (Thread here.)
VRBMB1 AIO Flash, available here. (Thread here.)
I'm going to assume you know how to boot into and use recovery.
NOTE: Do NOT let the stock ROM install any updates.
Starting with my CM11 M3 install, I did a nandroid backup. (Recovery is CWM Touch 6.0.4.5, but I doubt that matters.)
Flash the VRBMB1 AIO.
Wipe data and cache.
Flash the stock ROM.
Boot into the stock ROM.
The reprovisioning seems to happen as a part of ROM's initial boot up.
Send a few text messages to test. (I sent them to Twitter.)
Launch the Maps application, turn on your GPS and let it get a lock. If you don't, when you boot back into your ROM, you probably won't have working GPS.
This would be a good time to back up your IMEI if you haven't already done so.
Reboot into your recovery, wipe data/cache and restore your nandroid backup.
At this point, you'll be running your preferred ROM with a less archaic radio than my previous post.
DO NOT UPGRADE YOUR RADIO. The moment I upgraded my radio, the problem came back!
CM11 M3 will work just fine with the old radio. I've rebooted several times over the last few hours and it still works fine. (Time will tell if it's a long term fix or not.)

Notes: There are threads for the S4 with this identical problem. All updated information I have seen is listed above. If anyone knows more please post as I am going to keep this updated. If this does/doesn't work for you please post and let the community know. Feel free to hit the thanks button if it works for you.

This exact thing happened to me. I tried many fixes with no luck. After hours of hacking around in settings, I found a ROM of verizon's 4.3 OTA update and flashed that through ODIN. My texts are working just fine again. Kind of a cheap method of fixing my problem. I wish I could have taken more time to find a fix, but I needed to be able to communicate with people that day.
Stock 4.3 is kind of lame:
-4.3 is killing my battery faster than ever. CM11 had me going for days without charging and now I've needed to charge everyday.
-Stock 4.3 is laggier/slower than CM11. It tends to stutter for me.
-4.3 came with a new boot loader which no developers have exploited to install custom ROMs yet. This leaves you stuck with Verizon bloat. I hate all these damn apps. Going to try to safe root & see if I can't do some cleanup work.
Enough ranting. Just wanted to let you know you are not alone with this problem. Hopefully someone will figure it out. Missing my cyanogen mod already

It seems this problem has happened on other phones also running Cyanogenmod. I found this thread http://forum.xda-developers.com/showthread.php?t=2654822
It looks like the symptoms have all showed up at the same time approximately. (February 19th, 2014). Still looking for a better answer than going back to stock TW...
Edit: And another thread http://forum.xda-developers.com/showthread.php?t=2659280 This one suggests its all AOSP roms. But it seems many people are unaffected... I don't understand why/how.

SO this is the current status that I know.
The problem happens for everyone with a 570/717 area codes + on verizon + running Cyanogenmod (possibly any AOSP) + while connected to LTE which started on Feb 20th (the day before KitKat came out offically).
Current Workarounds:
Switch to TouchWiz based Roms
Switch your radios to be CDMA only
Call verizon and switch your number to a different area code
I know the workarounds all suck but that all I know for now. Switching SIM cards won't work. If I anyone knows anything more please feel free to let me know.

I'm 717

I have still be unable to find a solution for this issue. I think I have to give up on CM and go back to a TW based. If I hear anything new I'll update the post but I don't have the time to be wasting on my phone at the moment. If someone finds or hears of a fix or if it magically goes away as it started, please post it.
And spread the word if there are any other ROMs that this is occurring on. It seems the pool of those affected is just too small.

I have already had to give up. Been running slows tw. I take it Verizon didn't get back to you?

It won't. It isn't software dependent. People who had already flashed builds prior to the 20th magically had issues starting on that date, so it isn't a problem with new builds, and it only happens to those in the 717-570 areas so it isn't a problem with AOSP code. It has to be a Verizon network issue, I just have no idea how.

I have run TW base roms almost 100% of the time. Prior to the 20th, I had flashed cm11 3 or 4 times to see if camera worked and was never on it more than a day. I also had issues where music in my sd card wasn't being found but it was fine on TW. Could it be the unified build causing an issue? I have no issues on Clean Rom 8, wicked sensations or old and slows stock based roms.
*Edit* I have installed Gummy and CM 11 with PA Mini Modular apps and the CM Gapps from Invisiblek, let it set up. I then shut it down, removed battery and sim and then put everything back in and still the same issue. 1st text message goes through, then the rest after that just fail. I tried regular message app, Hangouts and Verizon messaging. All same results. I go back to my CR8 backup and all is fine. It's bizarre because everything else seems to be working fine and is very fast & smooth.

It can't be an issue with the unified builds because going back and flashing an older build yields the same results. If you're willing to make the trade-off, you can set your phone to CDMA only. Texts will send, but you'll have no 3G or 4G.

I'm ok with using CR8, Beans or other stock roms. Can't see paying for LTE and not using it lol. Was curious to see how aosp has been coming along and sms was really the only issue I was having.

I was using masta's 10.2 build for over 6 months without even thinking about flashing new builds. The 20th is when the problem started for me. Upgrading to CM11 didn't change it. I just installed Hyperdrive and everything is back to normal.
I wish I could go back to CM but it just doesn't work in this area. And I don't know what I can do about it,

[Q] No Cellular Data after getting back to stock

Hello everyone,
I was on Lollipop 5.1.1 Stock and not rooted then i decided to give rooting a shot. I downloaded Cataclysm and flashed successfully. everything was fine then i discovered that there is no Cellular Data connection. Rebooted and tried all possible things but didn't work. Finally gave up and flash Cyanogenmod 12. worked perfectly, nothing was wrong and cellular data was fine. After a while i wanted to come back to the clean stock lollipop so i downloaded and flashed Factory Image of Lollipop 5.1.1. Weirdly the Cellular Data doesn't work, i have no idea why or what may cause the problem. Please note that my Nexus 5 is from Amazon Germany. I doubt that there might be something wrong with the radio image ( meant for US models ?!! ) but i don't know really or have no clue what might be causing this !!!!
Any help is appreciated. Thanks in advance

FIXED
After spending 7 hours moving between different ROMs, i found out what was causing the problem of cellular data. The problem also exists after flashing stock image and Cataclysm. I noticed that on CM12 there was one option in the APN settings that was different from stock and Cataclysm. The MVNO type was set to None however in stock and Cataclysm it was IMSI. I don't know how or why would android change or decide that on its own and i also have no idea what does this option do. I guess that this may help many people who are suffering from the same issue ( also people who updated stock ran into same problem )

Don't know where you are but, every time that has happened to me a hands free activation fixed it.

Sprint Nexus 5 APN, 3G, LTE, SMS, MMS, all jacked up

I have a Nexus 5, rooted, unlocked. A couple of months ago, I started having data issues on CyanogenMod 12.1. Could not change APNs, couldn't really do ANYTHING about it. Tried modifying telephony.db files to no avail. Tried deleting them and letting new ones generate (they generated but it didn't help). Tried copying the telephony files from a working nexus 5 over and it worked for 5 minutes.
Eventually I flashed CleanCore and CleanCore 's radio. That worked BEAUTIFULLY and I had no Data issues for a long time. Well the other day, I went back to stock, upgraded to the most recent Nexus 5 Build and now no matter what I do, I can't get it to work. Tried reflashing CleanCore (nada) CyanogenMod 12.1 (nada) CyangenMod 11 (Nada) Factory Reset before AND after flashes (nada) I am barred access to APN settings on ALL roms I flashed and NO changes I make stick.
I have a Nexus 5 that is no good to me unless I have Wifi. and Even then, what good is that?
Please help.
Edit: Im thinking the problem lies soley in the APN settings being broken. Does somebody have a current flashable Sprint APN file? Im desperate people. I dont have a phone right now. And Sprint told me they were stumped (nice right?)

if that doesnt work download the stock image from google and manually flash those and then if that still doesnt work flash that zip after a reinstall of twrp hopefully that should work @NexusGazer

What ROM are you running that with? I tried flashing it with the latest cm 12.1 nightly and no dice. It flashed successfully, but I didn't have data, and the standard and non standard troubleshooting methods didn't change anything.
Then attempting to access apns went and wiped em all away again. And ideas @R800x_user

..

Have you flashed the sprint.zip by any chance? After flashing any rom and try cataclysm that one should work with the sprint n5. Data was working fine on that @NexusGazer

[q] need help with no service and no mobile network available

I have no service and no cellular network problem on my N5, running dark rom 7.1.2 aosp, with franco kernel ( never had issues before ), newest radio and bootloader. This started happening when i got my new sim card from my provider and i got 4g signal in my area for the first time. I tried manually selecting radio by going in the hidden menu by entering *#*#4636#*#* and i got lte and full bars signal after selecting band 8 ( 1800 hz ) but only for a minute then it went back to empty triangle. Tried selecting 3g only in preffered network, tried manually selecting provider, tried toggling airplane mode on/off a bunch of times nothing works. Any suggestion would be highly appreciated, i love my N5 very much and i would hate to throw it in a drawer somewhere. Thanks in advance

If i can get it to work with 3g i will be satisfied because i did some digging and found out that my network provider which is Vip MK has no lte support for nexus 5 d820 ( my model ) only 3g, but i can't even connect with 3g selected. I guess because this one is for US frequencies it will not work whatever i try but i will give lineageos caf a chance.

I was able to get 3G only to work on my Nexus 5 by reflashing the EFS from 6.0.1; I'm trying right now to see if I can install PureNexus 6.0.1 then dirty flash to PureNexus 7.1.2 with any success. Also, I might just switch to T-Mobile, but I have to wait until later this week for that.

Hi,
LTE band 8 is not in 1800 MHz but first of all you can check your N5 model - US model is D820 and is not supported for LTE on 1800 MHz (band 3). For 1800 Mhz band you need D821 model.

To clarify that:
You had the problem with not recognizing the sim or having no service at all. And you solved this by flashing the sstock 6.0.1 backing up the efs, flashing to Pure Nexus 7.1.2 and restoring the efs immediatley after flashing the rom (+kernel+root+etc)?
This solves this mysterious no sim/no service bug, which many (?) N5 owners experience? If this is true, I'd be really happy

It didn't stick. After I lost it I was unable to get it back. I gave up and switched to T-Mobile, where it is no longer a problem. Apologies for not having more testing information. I was able to get solely 3G on multiple instances, but getting the elusive 4G was beyond me.

I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:
View attachment 4196236
I can't remember or find the thread, so I post the images here:
- Bootloader-hammerhead-hhz20h.img
- Radio-hammerhead-m8974a-2.0.50.2.30.img
I think I had to flash them twice because the first time it wasn't right, but there were 4 months since then and still no failure

I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:

I can't remember or find the thread, so I post the images here:
- Bootloader-hammerhead-hhz20h.img
- Radio-hammerhead-m8974a-2.0.50.2.30.img

Thanks for your input. I'll check that when I have some time. This is really weird as it looks like a hardware problem but if you can fix it with this method it's clearly a software issue...
