[Q] No mobile network after flashing roms

[Verilin]

Would like some help. I have flashed CM 11 and can't make calls. It says mobile network not available. Tried flashing AOKP rom as well and same thing. Mobile data works fine, although i have gotten a popup twice that says 'Google Play Services not supported by your device, please contact your manufacturer' (no noticible issues from this, google stuff i've tried so far works). I have included a screenshot so you can see my baseband and rom version, etc.

Now, i had a great deal of trouble getting a rom flashed to start with, CWM put me into a bootloop and TWRP wouldn't flash anything because it said it couldn't mount /storage when i tried. Used Philz advanced CWM (love it btw, will be using it from now on). Still wouldnt flash the hltespr specific CM11 version so had to use the unified hlte version (it gave me the status 7 asserts issue, but editing the asserts out just gave me a bad file error when flashing). I wiped data/cache/dalvik between each flashing. I don't know if any of that would have bearing on this problem, just including any details i can. Any advice?

Have you upgraded your bootloader to NH7? I know most of the newly-updated CM-based ROMs require you to be on NH7 before flashing. That's most-likely why you weren't able to flash the htlespr ROMs. The unified ROMs no longer include the correct APNs for Sprint, so that's why you don't get service on it. I don't know why mobile data works on it.

No, didnt realize that i needed to do that. I'll do some research on it because i don't have any idea how to update the bootloader. If you have a link to a good tutorial that would be wonderful! Thanks!

Ok so i tried that, found this tutorial, followed it, no luck. Tried full wipe/reset after that to see if it would let me install the hltespr versions, still no dice. Same situation, mobile data works, calls don't. Will have to wait till daylight to try texting so i don't wake anyone up but i suspect that texting won't work either. Has anyone experienced this and fixed it? Lol i really didn't drop $100 on a phone to be saddled with all the Samsung and Sprint baloney that it comes with, don't wanna unroot....

 

[Verilin]

Bump

Anyone have ideas on this? Have continued to try fooling around with the udater-script file to resolve the status 7 problem so I can install the hltespr variant, still no dice. Please someone help!

 

[Verilin]

Bump!

Sorry, I typically don't have access to XDA forums on the weekend, so couldn't answer your question till now.

You flashed only the baseband/modem, not the Bootloader. If you want to update the Bootloader, you need to use ODIN to flash the Complete OTA NH7 Update.

In order to update the Bootloader, you need to make sure that you use the PC ODIN (not the mobile one) and that you completely power off the phone before you enter download mode (don't access download mode by using the extended power menu when shutting down the phone). I don't think you need to do the battery pull that Freeza had in his instructions (I didn't do it when I ODIN-flashed the NH7 OTA update), but it wouldn't hurt to do it.

Thanks for that, I will try it as soon as I get home tonight! The next thing I had decided to try was to unroot, to back to stock, then try flashing that before I start with the custom recovery and ROM. Do you think I should do that first before doing the whole thing or could that work just flashing that with my phone as-is?

Well, I always recommend a full wipe (data, system, cache, dalvik) when flashing ROMs. I haven't wiped my internal storage or external storage since I got the phone, so that's not really necessary.

I don't think that unrooting your current ROM is necessary. Flashing the ODIN OTA update will automatically remove root access, so that's not an issue. Here's the steps I took when I updated to NH7 and installed my current ROM (see my sig):

1. Make a Nandroid backup.
   I always do this just so I have a "record" of what I left behind. It also allows me to have all of my app data that I can restore via Titanium Backup (you have to buy the Pro version in order to restore specific apps from a Nandroid backup). I always store a copy on my ext. storage and on dropbox.
2. Do a full wipe
   As I mentioned above, I always wipe data, system, and the caches when flashing ROMs. While I have to take some time to get the new ROM exactly as I like it, it minimizes any potential FCs and errors that some people get when dirty flashing.
3. Install NH7 all-in-one via ODIN
   I installed the NH7 via ODIN. Please note that this is the fully stock, unrooted ROM and will also install the stock recovery.
4. Let the phone boot and connect to Sprint. Update Profile and PRL.
   I do this periodically whenever I go back to stock (from AOSP). I rarely have connection issues, but updating the PRL an profile can help with those.
5. Install a custom recovery using ODIN.
   My recovery of choice is TWRP, but others have found just as much success with CWM and Philz. Just make sure that you're installing the correct version of the recovery (4.4.X version, not the 4.2.X version). I always reboot to the main system after installing a recovery, but that's up to you. In the rest of this post, I'll say "TWRP," but I really mean "custom recovery."
6. [OPTIONAL] Make a Nandroid backup of the stock ROM
   I always do this, but I recognize that it's not necessary, especially since we can just ODIN back to this image at any time. I just like having the option of having a stock backup on the device (in case catastrophe strikes while I'm away from a computer).
7. Use TWRP to flash your AOSP ROM of choice.
   If you haven't installed any apps or messed around with the settings, you shouldn't have to wipe before flashing, but (in case you haven't noticed by now), I tend to err on the side of caution, specifically: wiping everything (data, system, and the caches) before I flash anything.
8. Set up the ROM how you like it and [OPTIONAL] make one last Nandroid Backup
   Whenever I set up a new ROM to the exact way I like it (statusbar settings, accounts set up, apps installed and configured, etc), I make a nandroid backup of my device. This allows me to go back to that "fresh" image whenever something happens to the device and I don't have to muddle around fixing those minor tweaks. Again, I tend to err on the side of wiping the phone too often and taking too many backups, but I've rarely had issues with my phone and ROMs because of it (to the point where I can spend most of my XDA time helping others with their phones), so it might be prudent to follow the advice.

Anyways, that's how I upgraded to NH7 and installed a custom ROM. Others may take a less conservative approach and you're welcome to adjust any of the optional steps.

Hope this helps!

OK, did all that successfully, when it went back to stock stiil had the same issue. Mobile data functions, mobile network for calls/SMS doesn't. Did the whole update prl/profile and even tried reactivating from settings, still nothing. Was able to install custom recovery (Philz) and the hltespr CM11 variant instead of the unified generic version. Still has the same problem, mobile network not available. Everything else works perfectly. I did verify in settings that it still wound up as the NH7 after everything I did. Note I did a full reset before each thing that got flashed in this process, and one more for good measure after. Let it boot to the system between steps too.

Lol I've been rooting and switching between ROMs for years and have never encountered anything like this. I'm stumped....

Dumb question but are you a Verizon customer or Sprint?

Sprint, I've had big red before but when they did away with unlimited data it wasn't worth paying their high rates.

 

[Verilin]

Bump!

 

[Verilin]

Anyone have any ideas on this? I am just confounded as to why this continues even after being reset to stock.

 

[RaphB]

Same Issue!!!

I have the exact same issue and have been trying to resolve it for the last 2 days... Did you find a solution?

 

[wallywallywally]

I have the same problem on a Samsung Mega. LTE and 3G data work but phone won't dial if LTE is active. It WILL voice dial if only 3G is active. Sprint. CM11.

I had this problem after flashing ROMs as well, but went into Settings>Connections>More Networks>Mobile Networks>Network Mode and selected LTE/CDMA....no network had been selected. That fixed me right up. Weird part is, I could still avcess the web without WiFi....but couldn't make calls or ise my bluetooth headset until I had performed the above steps. Hope that helps.

thanks forget the little things reset wifi and sprint cell extender
