[Q] No Mobile Data on CyanogenMod 12.1 nightlies - Sprint HTC One (M8)

I have a Sprint One M8 Harmon Kardon edition. I'm running a recent CM 12.1 build (updating doesn't help). I have no mobile data at all. I can't even enable it, the switch is grayed out in settings. I've tried restoring to the latest stock OS, wiping, reflashing CyanogenMod, flashing the RUU, running a firmware update, etc. I feel like I've tried everything, I really want to keep CM on my phone. Some have suggested to me that this my be an APN setting issue, but as this is a CDMA model the menu is not present to edit these settings. Does anyone know what my issue is or how I can check my APN settings?
Thanks.
EDIT: It appears they fixed the toggle issue in the May 17 nightly, still no data. Must be an APN issue, no idea how to get to those settings.
EDIT 2: Added APN settings shortcut via Nova Launcher, not sure why that is hidden. But I added the APN settings for ispsn and cinet.spcs (for MMS/LTE). 3G and MMS now function, not sure about LTE, can't test that right now. It should work fine. Consider this solved!

Get MMS/Android Market working on Metro PCS Flashed phone?

I flashed my phone successfully over to MetroPCS, but MMS and the marketplace is not working. Data works however. Can anyone point me in the right direction?
Wow my first post!!!!
Damage Control V1.0 or v1.1 (which is based off of the Eris) wil get you there. Sadly, this rom is no longer being updated, so us MetroPCS Hero users are stuck. I have tried all the latest roms, but MMS will not work. I am even willing to try an Eris rom, but I have not seen any thread that mentions if it's possible or not.
Good Luck.
Hey, if your ROM supports phone codes, you'll have to configure MMS using DATA (3282) which should be entered into the phone keypad as one of these
##3282 <dial>
##3282#
##3282# <dial>
from there, the MMS server is listed. Flashing to a different ROM will reset this.
Check out this thread for MetroPCS provisioning..

Edit: Are you using a custom ROM, or is it stock? If the unit is rooted and on a custom ROM, I know that Fresh ROM does support these codes (and is just a great ROM in general). For future reference, d-shade included in his ROM thread, a program called "APN Backup & Restore" to backup MMS settings and restore them in a different ROM.
Thanks for your response.
The unit is rooted and on custom rom. I personnally have tried all of the latest ASOP and Sprint based roms available. I have used APN Backup & Restore to copy and restore my settings from Damage Control v1.1 rom. No Luck. I have tried changing the DATA settings. No Luck. SMS works, but MMS does not. From what I understand, Sprint based roms do not have the messaging structure that MetroPCS uses. Verizon does, and that is why Damage Control v1.1 (Eris based) works. Voicemail is also an issue with Sprint based roms for us MetroPCS users.
If someone has have success with a Sprint based rom with MetroPCS, please share.
In the HTC messaging app, under settings will be "Connection Settings" which will show the MMSC, but not allow you to change it. I have never gotten MMS to work using AOSP/stock Android messaging.
By entering basic provisioning (DATA/3282), EPST should let you edit all settings. Let me know if the dialer doesn't open EPST. When EPST opens and you enter your MSL for edit mode, the MMSC is listed under "Advanced". Once you change the MMSC and go to Menu>Commit Modifications, it will tell you "No changes made" unless you change another settings (I just change the SCI to something different) I was able to edit it on the Fresh ROM I posted earlier, and my carrier uses Verizon's method for messaging.
For the voicemail issue, refer to this post. Voicemail is usually the only issue I have flashing Sprint ROMs.
Thanks again.
Believe it or not, I have tried everything you suggested already. Despite that, I did try the rom you suggested again and double checked all my settings. I don't know what is different about the Eris rom, but Damage Control v1.0 or v1.1 is the only rom that is fully working for MetroPCS Hero users right now. This rom is great, but my only fault is that it is no longer being upgraded, and I cannot find an ESPRESSO lockscreen that prevents the menu button from unlocking the phone. I am not a big fan of the vanilla or other lockscreens.
Thanks.
Not sure what to tell you at this point, but I'm positive there isn't anything you could be doing wrong. I'll go ahead and try a Damage Control ROM and see what happens, since it is Eris-based. And I honestly don't blame you at all about your lockscreen preference. Thanks for your feedback, though. Are MMS and voicemail the only problems you're having when using a different ROM?
Yes. MMS and Voicemail are the only problems that I am having with other roms. Depending on the Rom, voicemail works if I flash the PHONE.zip file, but I still get the annoying voicemail connection message . With AOSP roms, the voicemail works perfectly. MMS does not work with either.
Since VM is a known issue, I'll just say to focus on MMS for now - is the MMS server in the thread I pointed out earlier the most recent one (that you're using on Danger ROMs)?

Yes it is.
For the record, this is the thread that I am following.
forum.xda-developers.com/showthread.php?t=730289
As I said before, I'm not on MetroPCS right now, so I have no way of testing any of their proxy information. There is only one other thread I've noticed so far, in the Eris forums.

I'm not 100% sure but it does sound like a bug with the ROM. I suggest reporting it in their thread.

No Data On Cyanogen or RR

After unlocking and rooting my stock system, it still worked fine, but I wanted more features so I went to a custom rom.
Neither CM12.1 or RR had mobile data for Verizon.
When I flashed by TWRP backup of /system, I had data again.
According to 6Binford, my APN settings are correct.
Thanks!
If you upgraded from something other than the most recent -44 build, I think you need to update the radio. You can find that in the official CM thread for the Turbo.
I've tried flashing radio files but still no data.
I've also noticed this notification every now and then, even though I am in an area where data works perfectly fine on stock ROM, and even though before this pops up I still had no data:
Data roaming

You've lost data connectivity because you left your home network with data roaming turned off.

[SPH-L720] Universal APN Fix for Multiple Carriers [Android 4.x+] [Oct 2017]

Universal APN Fix for Sprint S4​
Hey guys. So I've had quite a few issues with my Sprint S4 as far as stock roms go. I decided to install a custom rom called Vanir and try it out. Well an issue I ran into was I could only get 3G to work. 4G LTE wasn't working. So what I ended up doing to solve the problem was quite simple. I believe this will work on pretty much any Sprint phone with the issue. The cause is the APN's.
Things you need:
Universal APN Fix - androidfilehost.com/?fid=24531035584725098 - Since I can't post links being a noob
Sprint S4
Custom Recovery - TWRP/CWM
A few minutes.
First I would like to say that this method isn't sure to work for all devices but it worked fine for mine. It was just a little bit tricky. So with that being said, anything you follow from this is completely at your own risk.
So what do you do?
The Steps:
Put the Universal APN Fix on your phone. Rather you do so via USB or by downloading it on your phone.
Reboot into your recovery.
Flash the Universal APN Fix in your recovery.
Select the carrier you use.
Reboot your phone.
Go to settings.
Find your APN settings.
Click on the menu key on the top right of the APN settings and select Reset to Default
Then select the APN that displays.
Profit
You should now have LTE. If you don't, make sure you are in a LTE area. You can also restart your phone and see if that helps.
I personally don't know anything but this helped me so I figured I'd share. Hopefully anyone else having this issue can solve it.
This does work on 7.1.2.

No data on some roms

Hello! I'm relatively new to the 3t (coming from the 6P) and have had issues getting data or voice with any rom that isn't based on Oxygen OS.
I have tried using recommended firmware with mixed results. Currently I am on DOT OS 1.2 with the latest Nougat firmware and can get calls and text messages but without any consistency. However I have no data whatsoever. I make sure to clean flash each time and have gone to stock (full clean flash including data) then back to custom.
Has anyone else experienced this or have any ideas?
Thank you!
Have you checked your APN settings?
Sounds like the default APN settings for your network is faulty in non OxygenOS ROMs. Like previous post I would recommend you to double check your APN settings with phone provider and APN settings recommended on their support webpage.
That solved it! Thank you so much. Switched from FI to at&t so it make's sense now that this became an issue now.
