[Q] CM10 on Rogers, no LTE.

All right, so, I have tried everything I can think of, but nothing has worked, so I decided to try asking here. I am have been on the CM10 builds for about a week, and I am loving them. I never really liked sense, so an AOSP JB rom is great (aside from the battery life). Before CM10, I was on ViperXL, and LTE worked fine, but after switching to CM10 (or any other AOSP roms) it just stops working. I can get everything else, Edge, 3G, and HSPA, but LTE just won't work. Just a couple hours ago I did a wipe and a clean install of the October 3rd nightly, and I am still having the issue.
One thing I haven't tried is flashing a 4.0.3 rom, and then the CM10 rom, but the FAQ says that issue has been fixed so I doubt it would help.
Anyway, thanks in advance for the help!

Check your APN settings. These settings worked for me.

I've had the exact same issue. I'm on Rogers too. I've double and triple checked the APN (ltemobile.apn) and it is definitely correct. I first noticed this on PA, and now get the same thing on CleanROM. Yesterday, I ran the Rogers RUU and that got LTE. So I went back to CleanROM (same radio image) and now only get HSPA. If I try to use the ltemobile.apn APN it fails with the message "Connection failed due to incorrect APN setting." Hope this info is useful for anyone with educated guesses

I checked, I had all that set correctly, still no LTE
If anyone else has suggestions, I would be glad to hear them.

From my experience i've had no issues with Rogers LTE on Sense roms and CM10. I would probably try deleting the APN and re-adding it.
I'd also check the network type. In dialer, dial *#*#4636#*#* and under Phone Information check that the network type is set to 'GSM/WCDMA/LTE auto'
Beyond that, trying running the latest Rogers modem/baseband. I'm using 0.18as.32.09.28L with no issues.
I've only had my One X a week so beyond this, i'm out of ideas.

there is an option in setting...you have to change from wcdma to lte...in mobile settings...
i can confirm lte works with cm10...worst case try flash a 4.0.3 rom then flash cm10..

Here's my experience: you no longer need the sense flash method. Make share you do a system, factory, cache and dalvik wipe. Do system and factory twice, as it did not always 100% work for me.
Then boot up. Go to apns and delete all the non-lte ones. Set the lte/wcdma/gsm setting there.
Next go to *#*#4636#*#* in dialer. Check phone information so that network says lte/gsm(prl).
Reboot and hopefully it will all stick.
Also I noticed that the default lte APN has port 80 and not MMS port 80. Make sure that is correct

Okay, I've made some progress on this. I did a factory reset and system wipe from TWRP recovery then re-installed CleanROM 5 from scratch. When it booted up I added the ltemobile.apn APN. This time it successfully connected to the APN, but it still did not get past HSPA. I then booted back into recovery and replaced /system/build.prop with the build.prop from the Rogers 1.94.631.3 stock ROM (http://forum.xda-developers.com/showthread.php?t=1812544). When it booted up it got LTE coverage.
So there must be something key in build.prop required to get LTE to connect. I've attached the two build.prop files in case anyone with trained eyes wouldn't mind diffing them and suggesting what setting might be the key to unlocking LTE.

With CM10 I had to delete the APNs and re-add them, even if they were correct. Not sure why.

Any chance you have figured out how to get it working on CM10? I tried the other suggestions, like deleting the apns and then entering them again, wiping everything, and I checked that the network was set to lte/gsm(prl). Still no LTE unfortunately.

Nope. I'm still rockin' HSPA on CleanROM. Some day I will probably mess around with the build.prop to see if I can figure it out. I really have no idea though. You should try running the RUU just to see if you get lte like I did.

Just got LTE working on Rogers with CM10, finally!
1.) First, I flashed the official stock Rogers ICS Baseband/Modem. You can check to see if you already have the correct modem by going to Settings, choosing About Phone, and checking your "Baseband version".
2.) Second, I corrected the APN settings that come default with CM10. The APN for ltemobile.apn need to be change, since the CM10 settings incorrectly set the Port as 80 (should be left blank), set the MMS port as blank (should be "80"), and set the APN type as something along the lines of 'default' (should be either "*" or "internet + mms"). Make sure you click the menu hardbutton and choose "Save", and go back and check to see that it did indeed save. I also selected the Rogers LTE amonst the list of the four different APNs (Rogers, Rogers LTE, Rogers Tethering, Rogers WAP - not sure if this last step makes a difference but this is what I did anyway).
3.) Go to your phone dialer, and type in *#*#4636#*#*. A "Testing" menu should pop up. Select "Phone information", scroll down to the bottom and under 'Set preferred network type", I chose "LTE/GSM auto (PRL)".
4.) Voila, this worked. I did not need to restart, just gave it a minute and the icon changed from H+ (HSPA+) to 4G (LTE). You can confirm LTE status by either doing a speed test and seeing the results, or go to Settings, scroll to the bottom and choose "About Phone", then "Status", and under "Mobile network type" it should say LTE. On mine it said "LTE:13".
Others, please experiment and try to see if you get the same results.
Cheers

This I think is the main thing. I'm on AT&T but up until just recently every time I flashed an AOSP ROM I had to go into this menu and set it to LTE/GSM. It would always default to WCDMA Preferred for some reason. It doesn't happen anymore but it used to happen every time I flashed an AOSP ROM or even when I rebooted. I had to change it and then it would be fine until I rebooted again.

Thanks, this worked on my SGH-I727R on Rogers.
I wonder why the apn settings load wrong in CM10 when the system reads them from the SIM card...? This never happened to me on previous aosp ICS roms.

what setting do you have for the tethering apn?

It's funny you posted this. I am on AT&T and recently I have not been able to get tethering devices to work, but up until recently, I have never had a problem.

my bud has the same phone unrooted with rogers gonna check his apn settings and see if they differ.

K well I just got off the phone with rogers. All the APN setting are fine but still no tethering. Well if it don't won't it don't work. If anyone is successfully tethering on cm10.1 build Jan 12 2013 with Rogers plz let me know.

[Q] trouble finding apn menu

I have 2 N5's, but under settings>more>mobile networks I dont have Access Point Names. All i've got is Data enabled/Data roaming/ Network mode/ system select/ and carrier settings. So now I would like to put my AT&T sim in and actually use LTE, but no APN menu. These are Sprint N5's not that that should change anything. Thx for any help.

I wish, just Update PRL, and Update Profile. so far I have not been able to find it anywhere
Now on my Samsung Galaxy Note LTE, it's easy to find lol.

by the way, just to help someone help me, I'm on kit kat build version: KRT16M. Baseband M8974a-1.0.25.0.17; Kernel: 3.4.0-g9eb14ba

On my Nexus 5, it's located under "Settings", then right under Data usage there is a "More..." tab.
That takes you to a new screen and under "Mobile networks" is the APN.
I'm on Telus, if that makes any difference.

I also think you have to have a sim card in place for the "APN" to be visible or active.

Yep, that's right where I'm used to seeing it. I'm guessing that Sprint has "hacked" the 4.4 OS and hidden the APN menu or something. I went into the store today and asked where it was and they didn't know (no shock there), but when they tried to update my tower settings they did a *#*#72786#*#* to reset the phone, and then did the *#*#8232#*#* and did some stuff that they wouldn't allow me to see.....
Anyone have an idea if the T-mobile N5's have been "molested"? IE APN menus and such are where they should be?

ok, after some more digging, it looks like the APN settings are all under the data menu using the *#*#3282#*#* to access it. It's all broken up instead of being in one list like in 4.3 and prior, but it looks like it's all there. now to find some apn settings for Sprint and AT&T to do some testing.

Its my understanding these are the same model phone. You might want to try just putting in your AT&T SIM if you haven't done that already. On my previous phone (Verizon Note 2), that changed carrier specific settings and loaded the APN automatically. You shouldn't have to do any dialer menu magic for GSM service. When I activated my Nexus 5 on AT&T we just stuck in the SIM and the AT&T rep configured stuff on his computer, nothing more needed to be done on my phone.

Yup, it worked without a hitch. Soon as I put in the AT&T sim the APN menu was right were it should be. Service was fast and clean. Putting the sprint sim back in proved problematic, but nothing a system restore couldn't fix. Thanks for all the help

ATT 5.0.1 to 5.1.1PR LTE connection issues

Hey everyone. I managed to go from 5.0.1 to 5.1.1PR but now I'm running in to an issue where I cannot send/receive data (play store, email, maps, etc). I can, however, send text and make calls. I went through the hidden menu setup with no luck. I've already tried the following: Restart (obviously), Factory reset, Reinstalling 5.1.1, APN settings. All no luck. Has anyone had a similar issue or does anyone have an idea of how I can fix this? Thanks!

I'm in the same boat and have done the same. I should of rooted and just removed what bloat I could. Which carrier are you using? Also, did you unlock your phone before going to 5.1.1PR? I didn't unlock my phone using the unlock code so I wonder if that could be causing an issue?

Funny. I'm having the exact opposite. I have LTE data, but cannot call or receive calls. I bought the phone stuck at AT&T logo thinking there was an att tot file. Instead used 950 5.1.1 PR.

Weird. I want to flash back to stock (ATT) but am almost certain I'm going to brick it. I'm pretty stuck in my current situation as I imagine you are, too.

I can replicate your situation by using LTE Band 4. When i try to make a call it immediately ends.
If you try Band 17 do you still have the same trouble? Did you try playing around with the LTE Bands and LTE-CA config?

If you have also rooted your phone, you can try getting rid of 80% of the Claro settings and brandings (boot animation etc...) deleting (or moving safer-moving) the /cust/CLR_PR folder and all of its contents. I moved the entire folder to my downloads folder and rebooted. First reboot I didn't get any boot animation, instead I got a dialog box with the good old android is working spinner, but subsequent reboots are now using the stock LG boot animation and configs. GSM/WCDMA/LTE auto is also now available from the standard network operator menu...
One thing I will point out is that I am NOT SURE if I am actually getting LTE speeds, I only see the 4G icon, not the LTE icon in the status bar. About Phone -> Network is showing LTE though.
Good luck, if you try this and blow something up, please don't blame me - but hey at this point what do you have to lose?

Why can't we just flash back to AT$T 5.1?

I tried band 4 and then I lose my signal altogether.
I checked speed and download was in the high 30s upload only around 3 or 4.

Well....I figured it out..at least what my issue was. Sort of feel like an idiot...lol. Even though the network auto detection found Cricket I went into the APN settings and plugged in the data below. It immediately displayed HSPA+ in the top right corner where the signal is. I confirmed it got me online so then I dialed the 277634#*# to set the LTE using the settings from the initial post. It should be LTE because the HSPA+ would be half the download speed. Looks like my typical results on the LTE Moto G. This may not help the user who can't make calls but has data. Hopefully it helps others.

Awesome, glad its working... I started comparing the XML configs between CLR_PR and the original files in /system/etc, /system/media, etc.. but soon i gave up, just too much to go through, so I deleted the entire directory after i realized that if an overriding config was not found in the cust folder android would happily look in the original location and just use whatever defaults it had.

Sure, I used ex file explorer, enabled root explorer, navigated to "/cust" and then deleted the folder. That should be it, i don't think there is any type of persistent backup of the contents there.

Wow, for me after I flashed the 5.1.1 PR I got the 2G/3G/LTE option right away, and it was set at 2G/3G/LTE already. Also LTE worked just fine from the beginning, didn't even have to enter hidden menu. We use band 4 here, maybe the phone is already set for that band? But the LTE option appearing right away is weird I guess.
Now I don't know if I should root it to remove the Claro branding (especially the boot animation, hate that one)...

I moved the cust_pr file and got the exact same results in that the phone now shows 4g but says LTE in about phone, and the speedtest app confirms I am getting full speed at least for Cricket (8mbps) down.

Many parts of the world use 4G to represent LTE and H/H+ to mean 3G data. In the US, we get 4G for H/H+ and LTE because of carrier marketing. Since you removed the custom Claro profile, the phone is now showing the default symbol for LTE as "4G".

US Cellular and Cyanogenmod 12.1 "Cellular network not available"

Careful if you're in the Mid West and want to customize a 2015 Moto G. I have had great success with previous variants, but this one (XT1548) won't get back on the US Cellular network. Tried a few nightlies and the release version. No bars show, the status message reads: "Emergency calls only - U.S. Cellular", and when choosing US Cellular as the network operator it times out with: "Can't connect to this network right now. Try again later."
I found this post and was very optimistic that setting the Access Point Name manually would help, but I am unable to actually save the full APN. I can save it after entering the name & APN fields, and several more fields, but at some point when I enter all the data on that page and click Save, the new APN disappears.
I called U.S. Cellular's support number (888) 944-9400 and level two support was able to provide my MIN number but disavowed any knowledge of the remaining APN settings. When they understood that the phone was rooted I was read a dismissal and wished good luck. I tried entering the APN now with the correct MIN but again it deletes itself when I click Save.
I am going to try flashing stock since I need a phone. If anyone can confirm or deny the APN settings from the linked post I'd really appreciate it. And if there's some secret to clicking Save, I'd love to know that too!
Also, maybe it's because it's searching for a signal but the drain on the battery seems much higher than the stock ROM. It went down 25% in just an hour or so of trying to resolve this issue.
# Update:
It could be that the network type is incorrect. When I connect to adb, the prompt says "[email protected]_cdma:/ # ". But the service I use is LTE.

pushing APN via ADB
If someone adventurous is interested in pursuing this, it may be possible to shoehorn the APN settings in using ADB:

@loadcode Actually CM 12.1 wasn't tested on US Cellular XT1548, no one had this variant in those days. Try unofficial CM 13, if it works (I'm pretty sure it does) I'll port the fixes to CM 12.1 too

Thanks for the reply! I'm down for that! Where can I find the 13 download?

I did find this but the cellular still doesn't connect. It seems to try, and displays the SIM card icon next to US Cellular (only when I set the Preferred network type to 1g), but continues with the previously-mentioned symptoms.
Any other ideas? I didn't make a backup before jumping in. Does anyone have the original firmware that I could flash back on this device?

@Alberto97 Is it possible for someone to edit the known issues page for the Osprey to make other US Cellular users aware of this? This would have saved me a more-stressful-than-necessary holiday.
I think I found the original firmware, so all might not be lost.
Thanks for your work on this!

I have the virgin mobile variant.
It is also the same model as you. XT1548.
I along with others struggled to get custom ROMs to connect. But thanks to Alberto, it is now working
Try this
Flash Alberto's cm13 12-24 build from the site you linked above.
Once it boots, go to settings and click cellular networks.
Then click CDMA subscription.
If NV is selected, that is probably your problem.
Change to RUIM and reboot.
You may still need to add your APN settings, but maybe not.
Try it out. You just need to try a few things, I'm sure you will be up and running soon.

@hossman, thank you very much for the encouragement and the suggestions. I'd love to have your confidence with this but I've tried many different combinations of the APN, Service Provider & Preferred Network Type and nothing has been the magic US Cellular desires.
Like Alberto said, apparently no devs tested it on the US Cellular network.
If it'll help I could try to provide testing results but I'm also really eager to have a phone again. Even if I could use my SIM card in my old phone for now that'd be acceptable, but for some reason it doesn't work in the 2014 version. (worked fine in my 3rd gen until flashing Cyanogenmod, so I don't think the SIM is bad.)

If it helps with development, here's a log of the network join attempt:

What rom is your phone currently? Did you restore stock firmware yet?
---------- Post added at 02:10 PM ---------- Previous post was at 02:09 PM ----------
Goto dialer and dial
*#*#4636#*#*
Click phone information
Is your phone # correct?

The funny thing is I have had my carrier come up us cellular many times while trying to establish virgin mobile status

Sorry I did return it to stock. A (possibly relevant?) observation is that with the stock firmware, I have the option to toggle the CDMA roaming mode between home & auto. With the non-stock ROMs this was not listed.
For my reference if I attempt this again, and anyone else on US Cellular, here's the working APN settings from the device after I reverted to the original working firmware. All categories are 'Not set' unless otherwise listed here (even username & password):
APN Name (I assume this could be anything...): U.S Cellular
APN: usccinternet
MMSC: http://mmsc1.uscc.net/mmsc/MMS
MCC: 311
MNC: 580
APN type: default,mms,dun,hipri,fota
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
APN enable/disable: APN enabled
Bearer: LTE
MVNO type: None

Don't get discouraged.
If you want to try again, feel free to pm me and I can try to help...no promises but I'll try..

We're online with the 2/6 build of Marshmallow! I did have to manually launch the Cellular settings app and manually enable/click on "LTE" and it came online immediately! WOOT!

Caf 0.9 lte solution found - (4g)

I HAVE SUCCESSFULLY TESTED THIS, BUT WILL NOT BE HELD RESPONSIBLE FOR ANY NEGATIVE RESULTS, BY TRYING THIS, YOU AGREE TO TAKE FULL RESPONSIBILITY FOR YOUR ACTIONS, YOU HAVE BEEN WARNED
For Sprint and Virgin mobile users, i found a solution for LTE, (It will give you 4g for some reason, but it works).
EDIT: THIS NOW WORKS ON CM 13 ROMS WITH NO APN LISTINGS, HERE IS WHAT TO DO:
1. INSTALL ROM, FLASH GAPPS,
2. REPLACE APNS-CONF WITH THE ONE FROM THE BELOW LINK THAT I POSTED FOR THE CAF 0.9 FIX
3 SET PERMISSIONS OF APN-CONF TO 0644, REBOOT TO TWRP, DO FACTORY RESET.
4. WHEN YOU HAVE BOOTED INTO ROM, DOWNLOAD APN CHANGER BY ANNANDO FROM GOOGLE PLAY
5. IT WON'T SHOW ANY APNS, BUT JUST IGNORE IT AND ADD ONE ANYWAY WITH THE FOLLOWING INFORMATION (IT IS PART OF THE FIX)
For Sprint users: USE SPRINT FOR THE NAME, AND n.sprpre.ispsn for the apn name. set MMSC to http://mms.sprintpcs.com SET MMSPROXY TO: 68.28.31.7 MMS PORT: 80 MCC: 310 MNC: 120 BEARER: LTE
IT TURNS OUT THE ABOVE STEP IS NECESSARY. FOR SOME REASON, EVEN WHEN THE APN ISN'T SHOWING, IT STILL IS REQUIRED, WHICH IS REALLY STRANGE
FOR VIRGIN MOBILE USERS: DO THE SAME AS SPRINT, EXCEPT PUT n.ij.ispsn for the apn name.
6. After you have done that, do to dialer and press *#*#4636#*#* and go to phone information and, like in caf, turn off radio, set network mode to cdma/lte auto prl, (again ignore the fact it says its already set on it) turn THE RADIO BACK ON, LTE WILL BE ON AFTER THE NETWORK ICON GOES CRAZY AFTER A MINUTE OR 2.
Sprint and Virgin Mobile: You need to flash rom in twrp, (wipe data, cache, and dalvik cache before flashing, (DO NOT WIPE SYSTEM OR THE INSTALL WILL FAIL) then gapps, then factory reset, (To avoid force close errors due to gapps), When the rom boots up, sign into google play account, and download root browser. After downloading that, download the apns-conf file from here: https://drive.google.com/open?id=0B-KfJE4M0My6MnBiWWtoQW04U0U and replace the current apn-conf under system/etc with the new one you just downloaded, and set permissions to 0644, reboot to twrp, and factory reset (so the rom resets telephony.db) Then, after the rom boots up, go under mobile networks, to access point names, and the third one down will be a sprint one. Edit this one. Follow these guidelines for your respective carrier,
VIRGIN MOBILE Change the apn to n.ij.ispsn, and set the bearer to LTE Only, and Turn off the other option that is ticked under here. Then go to your phone dialer and type in *#*#4636#*#* It will bring up a menu, click on phone information menu. Then, once your in there, turn the radio off, and set the network mode to cdma/LTE auto prl, (It will already look it is on this by default, But Just Bear With Me) DO NOT MESS WITH ANY OTHER SETTINGS IN HERE UNLESS YOU KNOW WHAT YOU ARE DOING) Then turn the radio back on, and BOOM, you will have 4g. (The network indicator will look like its going haywire for a minute, but give it some time for the 4g to pop up).
SPRINT: Change the apn to n.sprpre.ispsn, and set the bearer to LTE Only, and Turn off the other option that is ticked under here. Then go to your phone dialer and type in *#*#4636#*#* It will bring up a menu, click on phone information menu. Then, once your in there, turn the radio off, and set the network mode to cdma/LTE auto prl, (It will already look it is on this by default, But Just Bear with me.) DO NOT MESS WITH ANY OTHER SETTINGS IN HERE UNLESS YOU KNOW WHAT YOU ARE DOING) Then turn the radio back on, and BOOM, you will have 4g. (The network indicator will look like its going haywire for a minute, but give it some time for the 4g to pop up).
I hope this helps somebody. Thanks for taking the time to read this, and have a wonderful day!

Thanks man, going to give this a shot

Does the built in APN editor in the ROM work?

Its strange, but it works, for some reason, you cannot see it. I know this because I can't apply my fix in any of the cm 13 ROMs without inputting the proper APN with the correct details. It won't show, but its there. I know that probably doesn't make any sense, but its the best way I can explain it. I'm not sure what is causing the APN to be invisible, but nonetheless it still has an effect, even with its "non existant status". Sorry for the long winded answer!
