I know i'm not the only one having this problem, its been posted about before but no answers so id like to see if someone else who didn't get to see those can see this and come up with a solution..
I use an unlocked G2X with Cincinnati Bell, currently running Weapon. I have no problem at all on any rom though that is 2.3.3, any rom over that like 2.3.4, 2.3.4 etc data has NEVER worked, not i had it but lost it when i rebooted, never . i've never been able to run CM7 or MIUI because of this, and yes before someone suggests it my APN settings are correct i've checked them 1000 times they are the same as when on 2.3.3 roms, i've hard booted after to try to get data flowing a million times, i've followed installation instructions 100 percent and still have never had data working on those roms.
even on the new CM7 where the APN issue is fixed, data still does not work. Its obviously something in roms over 2.3.3 that is creating this problem. I BEG, BEG someone please help find an answer i would love you and most likely donate. Thanks.
58 views and no ideas? anyone, please?
You obviously haven't been checking the Development Section lately. There are many threads on this issue, and it has been fixed already. (Well, for the most part)

obviously you didn't read my post. I have NEVER had data work above roms with 2.3.3, most people have it then lose it. I also stated that the new kernel from ttbal and the newest CM where the issues are supposedly fixed I still can't get data. Please, read my post entirely before replying, thank you.

Yeah I read this in the other thread unfortunately there isn't a apn at all t mobiles or not on CM when I flash it

I've been following the development threads, because I too have been having data issues deeper than just missing APNs. It actually seems to be an issue with the entire radio side as a whole on any rom that's not based on the factory firmware. It's become much more stable, but still I can only get a GPS instant lock immediately after a hard reboot and can only receive multimedia messages immediately after a reboot as well. Another thing I've noticed, is I will get a "No internet connection" warning whenever I open the browser, despite having a data connection, and the page still loads.
Also, why do I have to set all my carrier information (my phone number, and voicemail number specifically) when the other factory firmware roms can pull this from the sim card?
I love all the features of CM7 and it's based roms, but the data stability has made it unusable for me.

You can't edit T-MO's one. You can copy and make a duplicate of that and then edit it, but that just beats the point.
And yeah I STILL have the same problem.
I'm not a t-mobile customer so I need to add my APN manually. And yes after a hard I can see my list of APNs and I'm allowed to add APNs but still no data. even after the latest stable version. And even after that with the Dragon Kernel with the supposed APN fix.
Really hope someone can shed some light here.

oh ok try going into recovery menu and wipe all data then boot up again maybe then you can see the apn
Since you are rooted go into adb and try the following. Download the attached zip file and extract the "apns-conf.xml" file and put it in the same directory you run adb from. Then execute the following adb commands.
# adb shell mv /system/etc/apns-conf.xml /system/etc/apns-conf.xml.bak
# adb push apns-conf.xml /system/etc/apns-conf.xml
# adb shell chmod 644 /system/etc/apns-conf.xml
Then go into apn settings and press menu and choose to restore to default. The TMO one will still show but now your Cincinnati Bell one should show also; and it will be a default apn like TMO now (they are on equal footing now). Make sure you press the radio button to make the Cincinnati Bell one green, it it wasn't already. Hopefully your data will work after this. Plus you will now have global apn settings automatically for virtually any sim you use from a GSM carrier worldwide.

Thanks for the help, I'm not where near an xda and phone "noob" but i have never used adb I wouldn't feel comfortable trying to do that if it risks bricking my phone. Unless you have any opinion on how doing it or if its not really complicated I don't think I will try that.

There is no risk of bricking your phone if you stick to the commands I gave you. Just highlight and copy them and you can paste them into the command prompt window by right clicking and selecting paste.
Download the attached zip with the adb.exe and two dlls need for it to run. All you are doing is backing up the apn configuration file, replacing it with a new one and setting permissions so the phone can use the new file. Then you reset the apns to default and the phone will set the apns from that file based on the sim in the phone.
Go into settings, applications and turn on usb debugging, if it is not on already. Then connect your phone to your computer and make sure the adb drivers load (you can find the driver pack by searching this site or installing them from the LG Updater app). To make sure the phone is connected in the command prompt window type "adb devices" and hit enter. The phone should be shown as connected. If not, the drivers are not installed.
Run the command prompt from the same directory where you unzip the three adb files and put the apns-conf.xml file in the same directory. That makes it easier for you to do this. It is actually quite simple and will take only a minute or so.
Flashable zip to replace apns-conf.xml file
Here is a flashable zip that can be installed with clockworkmod recovery. It does the same thing but does not back up your existing file. If you are running a stock rom this will prevent an ota from installing. If you are running a custom rom it doesn't matter as you cannot get ota updates anyway.
Just boot into CWM recovery and flash this zip file. Reboot and reset your apns to default.
Ok sweet, should i flash it while on my current rom that works or flash CM7 then flash it?
quick edit- it won't effect my phone being unlocked and lock it will it? after those questions i'm done asking and i will give it a try good sir thanks

The phone remains unlocked once you unlock it. Nothing you will do will relock it.

GPRS data will not work, my default APN is mss.life.com.by, and I see arrows in my status bar, but internet not worked.
So, I changed it to internet.life.com.by(got it from operator instructions) and I anymore see arrows and internet still not work.

can you revert back to the factory or stock ROM, hard reset or something?
Thanks for the reply.
I did the factory data reset

Its probaly because there made in China, and they don't have original Android License.
Did you install a rom that was made for your phone, because it is chinese you know. And you should indeed go back to stock rom
I have installed the rom that was made for my specific phone
and the specific model that i have. (2 of them)
I flashed the phone to get the latest firmware that the phone maker
said was released to fix a lot of bugs.
The phone maker also said they had tested the flash tool
with the latest firmware and the phones were working OK at their end.
But in my case the phone although it was working fine before the upgrade
after the upgrade it shows in the status bar "Invalid IMEI"
and cannot connect to networks and make calls.
Any ideas anyone?

1-root it with "SuperOneClick"
2-install "root explorer"
3-copy the file "MP0B_001"
from the good phone to the bad phone.

Before rooting, the above file should have been backed up,

Hi Friends
I have been following the forum for a year and have finally registered as i found a question to which there is no solution i could find yet . .
I have a rooted Atrix 2 running NUMA http://forum.xda-developers.com/showthread.php?t=1960679
Its one of the best and most stable ROMS i have tried but i am facing one issue on it . .
I'm not able to use wifi tethering on my phone . .
A network is created and my nexus 7 connects to it but the internet simply does not work!
Any tricks to make it work?
Have FXZed several times and done fresh installs but no luck
Tried some apps to kick start it but they caused a reboot so i uninstalled . .
any fix for it?
Bump!
still awaiting a response . .

I've never had that problem, or any problem on NUMA. If I did, though, I would re-download the ROM and start over.
Did/do you have any additional mods or tweaks installed? Xposed framework and modules, for example?
If I had a dollar for every time I said that, I'd be making money in a very weird way.
I tried that . .even FXZed my phone . . . .
btw does it make a difference as i have an indian Atrix 2 MB865 but this rom is based on AT&T ICS?

Try changing you apn type to 'not set' in apn settings
Screenshot APN
Hi Guys i did read about the APN settings however i am not able to edit the APN settings and there is a lock on it . .
I have attached screenshot of the settings . .
Also i noticed another issue recently . .The phone auto reboots if i try to transfer files via Superbeam before QR code gets generated
Could this be a related issue as it also uses wifi tethering indirectly?

You can find apn settings for Airtel on internet. Just keep 'apn type' to 'not set' in apn settings.
This worked fine for me on Vodafone
Internet tethering is now working for me thanks to these settings i found. .
On the device, tap the Settings icon
Choose Wireless & Networks (or Wireless Controls)
Choose Mobile Networks and then Access Point Names
Press the Menu key and then New APN
Select Name, enter: Airtel GPRS and tap OK.
Select APN, enter: airtel-ci-gprs.com
Scroll down to APN TYPE and enter: default or (Select : Internet)
Press the Menu key and select Save
Tap on Airtel GPRS to turn it on
However I'm still unable to use Superbeam!
Phone restarts if i try to send anything through it . .
Phone was previously locked by ee,so i did tons of things,i think i damaged efs/imei(i don't have any backup)

Is it possible to rewrite change or whatever is needeed to be able to register on network without box?

Go to

And choose your network
If didnt work try to flash your mobile with latest Rom using (smart switch) keep in mind you will lose all data on your phone if didnt work try Marshmalow beta....any way try roms and do same steps...

Dude just restore this efs backup with twrp recovery https://www.mediafire.com/?loh80547x1k5cg8
It will say null or something then try to fix imei with apps inside folder...if this didnt work visit repair place...
Sincerely hope you're not in the UK as it's very illegal here to change IMEI and advertising the fact isn't a smart move.
Greetings,
Changing IMEI is illegal in many countries and the discussion thereof is prohibited on XDA.
Thread closed.
INTRO:
The mission of this thread is to make some potentially important information available to all users that have the SCH-S968C(All Tracfone carrier models) that has been gathered over the last year and a half for flashing CM/CM based ROMs on the SCH-S968C .
Though this information is available in many other places, I'm collecting it all into one place to try and make it as painless as possible for everyone with the SCH-S968C. This guide is a long one and has many steps but I've attempted to make it as straightforward as possible for those that are new to rooting and flashing.
BACKSTORY:
Starting from some time in 2014 there have been a lot of users with the SCH-S968C that have flashed a CM11/CM12/CM13 or CM11/CM12/CM13 based custom ROM and didn't have mobile data(3G) or even no cellular signal after flashing and were like:
"OH MY GOD! WHAT DID I DO!?"
Then they would start flashing other ROMs or flashing back to stock to straighten the issue out, only to find that didn't help and none of the typical or expected solutions would correct the issue. Many were flashing modems and swapping system files in an effort to get data working, all of which ended with either a non-working device or a bricked device, do not try the things they tried, that is not the fix for the situation.(if you are one of the ones that lost signal and can't get it back even on stock, I'll discuss the fix for that in TROUBLESHOOTING at the end of this guide).
THE REASON:
These users would have no signal after flashing because unfortunately, these ROMs are built for the Verizon S3 SCH-I535 but the SCH-S968C can flash them(it actually has the SCH-I535 Verizon motherboard with 4G disabled in the hardware, making it 3G only). The Verizon S3 is a 4G/LTE device, Verizon uses a CDMA 4G/LTE SIM in their 4G devices to regulate 4G data. This SIM requirement is built into the ROMs themselves. Even though the SCH-S968C is a 3G device, this makes these ROMs require a CDMA 3G/4G/LTE SIM when flashed on the SCH-S958C to receive at least data(some of the ROMs even require it for cellular service also, not just data).
The discussion of all of this about the SIM, what has been tried to bypass the SIM and the things discovered to leave the SIM and get everything working at its best can be found in THIS THREAD. Most of the issues and fixes for the KK and newer ROMs, all the troubleshooting and fixes associated to getting working data/MMS/SIM correctly configured along with restoring if you have issues can be found in the linked thread, mostly toward the end and not so much the middle.

]6[-CDMA 3G/4G/LTE SIM(absolutely MUST have a SIM or you won't get mobile data/MMS to work), below is a list of SIMs that should work and the results of using them, you'll need a micro SIM or a full-size SIM trimmed to fit micro(a nano SIM with adapter to fit micro will work as long as it is a CDMA, not a GSM SIM).
]*[Previously activated Verizon 4G LTE SIM.($3-5 on eBay)
(results are APN settings are accessible and mobile data/MMS works correctly)
]*[New, never activated Verizon SIM
(most users with a new SIM have working mobile data(3G) but have had issues accessing APN settings to get MMS working, some have had no issue accessing APN settings, some users with a new SIM also had a random dialing issue that would dial a *2289X number, the cause was never identified, this issue doesn't happen with a previously activated Verizon 4G/LTE SIM).
]*[Straight Talk BYOP CDMA 4G/LTE SIM(not the AT&T/T-Mobile SIM, those are GSM and won't work)(I haven't been able to verify if there is a difference between used and new ST SIMs but mobile data should work and if APN settings are accessible you should be able to get MMS working, hopefully users will post their results here with new and used ST SIM).

***PREPARING BEFORE FLASHING***
***NOTE***For the users that don't have a PC to do their downloading and file moving, I'll provide instructions for using ES File Explorer to do everything.***NOTE***
***NOTE***You can use your PC instead of ES File Explorer for everything EXCEPT copying /efs, this step will be done using the device to keep it simple for those that don't have PC and because PC method to pull a copy of /efs is a bit technical for the average user, I will only be explaining for using ES File Explorer.***NOTE***

]6[-It is recommended to make a NVdata backup to protect IMEI then save a copy of your /efs folder before flashing custom ROMs. IMEI is very easy to lose depending on what you flash and the order you flash it in with this device.
]*[(RECOMMENDED)Comprehensive guide to backing up IMEI/efs HERE
]*[For those that don't have a PC, open the Terminal Emulator app and type:
su(press enter, grant superuser/root permission if prompted)
Then type:
reboot nvbackup(press enter, the device will reboot).
]*[This saves NVdata/IMEI to be restored later if flashing wipes IMEI, instructions for restoring posted below in TROUBLESHOOTING).
]7[- It is also recommended to save a copy of your /efs folder on your extsdcard, we will use ES File Explorer. Open ES File Explorer and take note of what your extsdcard is labeled as and remember it, you'll need to know this later, then swipe from right to left to go a page over.
]8[-Tap the / symbol.
]9[-Press and hold the /efs folder to highlight it then tap the "More" button at the bottom.
]10[-Tap "Copy to"
]11[-Tap the arrow at the top left(what it says will be different depending on the ROM you're using).
]12[-Remember the name of your extsdcard? Select your extsdcard.
]13[-When you get to your extsdcard, tap "OK"(Those with PC can now connect to PC and save a copy of /efs on PC, you may have to enable MTP in the USB options that pop up when you connect device to PC to grant the PC access to device storage).
]14[-Open Titanium Backup(grant superuser/root permission if prompted while using Titanium Backup), backup all apps/data/settings you want to keep(Follow the guide I linked to determine what you want and what is safe to restore after flashing a new ROM, some things won't restore in a new ROM without causing issues), instructions for using Titanium Backup HERE.
]15[-To simplify moving files and to keep everyone on the same page when finding your files when you flash them we will create a folder on extsdcard and name it ABC(or whatever you want as long as you know which one it is), this will make it easy to find in TWRP when you flash your ROM.
Open ES File Explorer and select your extsdcard.(Those with PC can use PC to do this)
]16[-Tap the "New" button.
]17[-Tap "Folder".
]18[-Name the folder "ABC"(or whatever you choose) then tap OK.
]19[-Download the KK/LP/MM d2lte or d2vzw ROM(s) of your choice and store it/them in the folder you created on your extsdcard. You will find ROMs, custom recoveries, custom kernels and various other mods that can be used on the SCH-S968C in the links below.
]*[ROMs+other mods: HERE
]*[More ROMs: HERE
***EXTREME CAUTION***(DO NOT use anything that says STOCK/STOCK based or TW(TouchWiz) in its name, nothing that says firmware or modem, nothing that mentions Safestrap Recovery or Flashfire, locked Bootloader(BL). All of these things are specifically for the Verizon SCH-I535 and will almost certainly lead to hard bricking your device if you attempt to use them.***EXTREME CAUTION***
]20[-Download the appropriate Gapps for the ROM(s) you chose and store it/them in the folder you created(the version of Gapps you need should be mentioned wherever you get your ROM from).
]21[-Charge battery to full.
]22[-Now you're safely prepared to start the flashing process, proceed to the next steps.
***FLASHING TWRP***
It is recommended to always use the newest version of TWRP available for best results. If you already have the newest version then skip to FLASHING YOUR ROM, if you don't have it then follow instructions below.
To make this easy for those that are new or don't have a PC, we will use TWRP Manager or Flashify to flash TWRP, or by manually downloading the TWRP .img(linked above) then flashing it in Flashify.
***FLASHING WITH TWRP MANAGER***
]1[-Open TWRP Manager(grant superuser/root permission at any time while using TWRP Manager). Tap "Device Name".
]2[-Scroll down the list and select "Samsung Galaxy S3 Verizon d2vzw".
]3[-Tap "Recovery Version to install".
]4[-Select the newest version available.
]5[-Tap "Install Recovery".
]6[-The .img will download.
]7[-When the .img downloads it will prompt you to verify the partition to flash to, verify you have the same thing and tap "yes".
]8[-When the .img finishes flashing, you will be prompted to reboot to recovery, tap "yes".
***NOTE***Skip to BACKING UP YOUR STOCK ROM if you used this method to flash TWRP.***NOTE***
***NOTE***If you've tried this and you're having issues with this method, refer to the method below***NOTE***
***FLASHING WITH FLASHIFY***
]1[-Open Flashify and tap "Recovery Image"(grant superuser/root permission if promoted while using Flashify).
]2[-If you manually downloaded the .img(linked above as an option in PREREQUISITES), tap "Choose file", then select it from your download folder or wherever you stored it then skip over the next two steps below this one for downloading the .img in Flashify.
If you haven't manually downloaded the .img, skip this step and go to the next step to download the .img in Flashify.
]3[-Tap "Download TWRP".
]4[-Select the newest version available.
]5[-The .img will download(it will be downloaded in /flashify/recoveries/twrp/ folder if you ever need to find it.
]6[-When it downloads or when you select the .img from storage, it will prompt you to flash the recovery.img, tap "yup".
]7[-After it flashes, tap "Reboot now".
]8[ Proceed to BACKING UP YOUR STOCK ROM.
***BACKING UP YOUR STOCK ROM***
]1[-When you are booted to TWRP, if you are still on stock and you haven't made a NANDroid backup, make it now by selecting the "backup" option before you flash anything!(Very important step)
]2[-Tap "Select Storage".
]3[-Select your extsdcard(Micro SDCard), select OK.
]4[-The default partitions selected to backup are fine, swipe the slider to confirm, this NANDroid backup can be used at any point in the future to restore the device to stock if you have issue or ever want/need to.
]5[-Press the Home button in TWRP to return to the Main screen and proceed to FLASHING YOUR ROM.
***FLASHING YOUR ROM***
]1[-While still in recovery after making your stock NANDroid, remove battery cover and insert SIM then replace cover.
]2[-Tap "Wipe".
]3[-You'll see "Wipe Data, Cache and Dalvik(not including internal storage)" at the top, swipe the slider to perform the wipe and wait for it to finish.
]4[-Tap the Home button in TWRP to return to main screen, select "Install".
]5[-Select "Up a level".
]6[-Select "external_sd".
]7[-Select the "ABC" folder you created(or whatever name you chose for the folder, scroll down the list if needed).
]8[-Select your ROM.zip.
]9[-Tap "Add more zips".
]10[-Select your Gapps.zip.
]11[-Swipe the slider to confirm the flash.
]12[-After flashing, tap "Wipe cache/dalvik".
]13[-Swipe the slider to confirm.
]14[-Tap "Reboot System".
]15[-Wait for the phone to boot(It will take 10-20 minutes to fully load), when it boots into Setup Wizard, stop and watch the status bar Network Signal icon, wait for the device to detect the SIM, when the icons shows a signal(and 3G if you're lucky, if you are not getting any 3G then just get on WiFi to finish setup if you have WiFi or if you don't have WiFi, skip setup and go on to SETTING UP DEVICE AND SIM, you can sign in to Google to finish setup after you get the SIM and APNs set up), then go through Setup Wizard to set up the device and sign in to your Google account. When you're in the phone, continue to setup steps below.
***SETTING UP DEVICE AND SIM***
***NOTE***Your system settings may look different depending on your ROM but the settings should be the same or similar, find the settings described wherever they are in your ROM and set them to what is posted.***NOTE***
]1[-Go to System Settings>About>Build Number.
]2[-Tap build number at least 7 times quickly to enable Developer Options(you'll get a toast message saying you have enabled development options).
]3[-Go to System Settings>Developer Options.
]4[-Set Root Access to "apps and adb".
]5[-While still in developer options, verify USB debugging is on(neither is needed for setup but turning them on now prevents potentially confusing issues later).
]6[-Open your dialer app and dial:
*228(if your SIM is a Verizon SIM), press send, this programs the SIM, hangup when done.
OR
*2289X(if your SIM is a Straight Talk SIM(or any other Tracfone variant CDMA SIM). I can't confirm the actual number, I haven't used this SIM), if your SIM is a ST BYOP CDMA 4G/LTE SIM then this number should program the SIM, I can't confirm that though, if it doesn't we'll have to hope someone that used ST 4G posts what they had to do, hang up when done.
]7[-Go to System Settings>Mobile Networks(tap the words, not the toggle switch.
]8[-Set Preferred Network to "3G".
]9[-Set CDMA Subscription to "NV".
]10[-Select Access Point Names.
]11[-Then select one of the existing APN sets on the list(any set, it doesn't matter, do not create a new set, you have to edit an existing set or they won't save, your list won't look the same as mine).
]12[-Edit the APNs using either set I have posted, the Tracfone set should work on all Tracfone network variants. Change only the values listed.
]*[Tracfone APNs, enter the name of your Tracfone network Carrier variant in the Name value(These APNs are for all Tracfone devices including BYOP devices).
Name: (Your network variant)
APN: tfdata
Port: 80
MMSC: http://mms-tf.net
MMS Proxy: mms3.Tracfone.com
MMS Port: 80
]*[Verizon APNs(these will also work on the Tracfone variants since they are on Verizon towers).
Name: verizon
APN: internet
MMSC: http://MMS.vtext.com/servlets/mms
MMS port: 80
MCC: 310
MNC: 012
APN Type: internet,mms
]13[-When you've entered the APNs, tap the menu button.
]14[-Save the edited APNs, the set you create might disappear but they are still there and will still work as normal.
***NOTE***If you flashed a 4.4+ ROM first and now you want to go up to 5.0+/6.0+ and you have working data, now would be a good time to reboot to TWRP to flash the 5.0+/6.0+ ROM and Gapps like instructed in the above steps. When you get them flashed, do these same steps to make sure everything is set where it needs as you go back through everything.(or dirty flash with no factory reset, only wipe cache and dalvik after flashing and ONLY as long as it is an update to the same ROM you are using, for example, CM11 to CM12 or AICP 5.0 to AICP 6.0, hopefully dirty flashing will let you keep APNs configured in some of the newer ROMs that don't give access to APN settings instead of having no way to change APNs in your new ROM, also, some of the ROMs don't have the settings built in the ROM because they have World APNs so shouldn't need the settings configured)***NOTE***
]15[-Reboot the device to reload settings.
]16[-After the device reboots you should have working mobile data and MMS(You can sign in to your Google account now if you had to skip it in setup), install Titanium backup using the copy of the app you placed on extsdcard then open Titanium Backup and restore all the data you backed up in Titanium Backup, reboot after restoring data from Titanium Backup.(You will need to go to System Settings>Security>Unknown Sources and turn it on to install Titanium Backup if you're installing from a copy you manually saved, or you can install it again from the Google Playstore)
]17[-Remember to set Root Explorer and mount R/W in ES File Explorer as described in PREPARING BEFORE FLASHING section posted above before proceeding to the next step.
]18[-Once everything is set up the way you want, mobile data/MMS are correctly configured and all data is restored from Titanium Backup, you can boot to TWRP and make a new NANDroid backup of your custom ROM with everything working, this can also be used to restore later if you have issues. Remember, at this point you should have a stock NANDroid backup and a custom NANDroid backup if you've followed the instructions, either can be used when/if you need it. Reboot after making the new NANDroid backup.
]19[-Enjoy!!!

***Troubleshooting***
]1[-ISSUE-You've tried flashing a CM12/CM13 or CM based Lollipop/Marshmallow ROM but you are getting a bootloop.
]A[-POSSIBLE FIX- Did you wipe data/wipe cache/wipe dalvik cache before/after flashing then rebooting?
]B[-POSSIBLE FIX- When coming from stock to Lollipop or newer it is sometimes necessary to do a clean install when flashing the ROM, to clean install, Boot to TWRP, select "Wipe".
]*[Then select "Advanced Wipe".
]*[Then select "System" and "Data" partitions(do not select any other partitions). Swipe the slider to confirm the wipe.
]*[Tap the home button and continue by flashing ROM and Gapps normally as posted in FLASHING YOUR ROM above.
]2[-ISSUE- You flashed a ROM and lost Signal.
]A[-POSSIBLE FIX- Check Network Settings to verify you're set to 3G and NV, if you flashed a custom ROM before this and had working data then flash back to that ROM and check network settings in that ROM also.
]B[-POSSIBLE FIX- Check System Settings>About>Status>IMEI and verify you still have IMEI. If you have lost IMEI then follow steps below.
]*[(Recommended)-Refer to the Comprehensive guide to backup IMEI/efs to restore IMEI HERE
]*[-Open Terminal Emulator and type:
su (press enter, grant superuser/root permission if prompted)
Then type:
reboot nvrestore (press enter, this will restore your IMEI)
]*[-Restoring the nvbackup using Terminal Emulator erases the backup from where it was saved so you'll need to make another NVdata backup using the same method described above in the PREPARING BEFORE FLASHING section.
]*[-Copy your efs folder back to its location on your device(overwrite the existing file if needed), reboot device.
]3[-ISSUE- You flashed a 6.0 CM/CM based ROM and now your PC sees your device but isn't seeing your device storage.
]A[-Possible fix- When device connects you'll see a notification in status bar, pull down notifications and open options, select MTP.
***NOTE***THIS THREAD(linked above also) discusses various issues when flashing these ROMs and using SIM, remember to patiently read through it if you have issues and you'll probably find your answer, the issues and fixes are spread through many months of posts so it's not going to be a fast find, but with diligence to suffer through the agony of reading posts you'll most likely find your answer***NOTE***
Hello. Nice guide here. Only problem I have is APN settings not accessible with cm 12.1 and a new ST SIM card. Tried to visit link for different ROMs and everything on fixin SIM/MMS, but links are broken.

The links work fine for me, try a different browser or something.
As stated in my guide, new, never activated SIMs usually can't access APNs but previously activated ones can, get a used Verizon SIM from eBay for $3-5, they have APNs stored on the SIM, this allows you to edit them.
Or you can try different ROMs to see if APNs are accessible, some can and some can't because some of the ROMs have world APNs built in(these don't have APN settings), the ones without world APNs should be able to access APN settings.

Are the APNs saving when you can access them? If so then a reboot shouldn't reset everything. You have to edit an existing set or they won't save, creating a new set won't save, only editing existing sets works.

Leaving the rest of them won't harm anything, you can delete them if you want but once they are gone there's no getting them back.
In my experience, I've seen better results with a used SIM from Verizon, they are easy to get and cheap for $3 to $5 on eBay.

I didn't quite understand that, can you clarify what you're saying?
Are you saying the APNs are disappearing?
Typically on this device, when you edit and save they disappear but still work, that's normal for this device if that is what you mean.
Sent from my SCH-I535 using Tapatalk
After dialing *228 im given the apn list. One of them works from the start with no modifications and is named straight talk. But after rebooting the phone the list will be blank and say apn setting not available for this user(data works but no mms). If i dial it again the list returns and the phones mms works onces again. Im guessing this is the errors you have been talking about but i got the sim card befor your guild.
I will most likely buy another card used but im not much of an ebay user
And im sorry my English is vary bad

The apn it defaults to and works on is basically blank but it works. As long as i dont restart the phone. I have not tested to see what happens over a long period of time, my guess is it will eventually stop working again. But i will keep my phone on over night and see if i can mms in the morning

Wait before you get the SIM. I might can work something out for you. You're the first person to mention getting APN settings back after they weren't available and the first to mention that you lose them after a reboot. Does your data and MMS still work after rebooting?
I'm going to contact some developer associates of mine and see if we can't use this information to come up with a working fix for it, if so, you won't need another SIM but if you'd rather not wait then go ahead get the SIM.
You have me curious to see if there is something useful that can be done like writing a script or something to run at startup to keep your issue from happening. Whether its a script or not there may still be a chance there could be a small breakthrough for this device when using these ROMs.

I am more than happy to wait I'm more interested in the process of getting this to work then I am updating my phone after a reboot and APN settings disappear I lose the ability to MMS but I still am able to use data.

In the meantime, if you want to use MMS you can use Hangouts or a third party texting app from the Playstore, there are several different ones, third party texting works fine, its the stock messenger in these ROMs that doesn't work without the APNs, third party doesn't need it.

Yes, but some of the third party apps don't require the other person to have it.
BTW, if you use the reply button under someones post(if you're using a browser) it will quote whoever you're replying to and they'll get a notification to let them know you replied.
Or if you're using an app to view this form, tap the persons post then tap reply and it will quote them.
This way they know you replied instead of having to purposely come look to see if you replied.
You can also give someone a mention if you want to get their attention by putting @ on the beginning of their name like this @stoneman1924, this also gives them a notification that you mentioned them so they'll know to come look. It makes it easier for everyone if you use the quote system and the mention system. I've quoted your post every time I replied, it gave you notifications that I had replied to you so you could check my reply didn't it?
