[Q] No LTE after rooting and installing cyanogenmod 11 - One (M7) Q&A, Help & Troubleshooting

I've rooted my HTC one, installed cyanogenmod with TWRP and LTE stopped working. Before (on stock) it worked perfect.
3g is fine and when I switch to LTE I'm dropping it (to be clear LTE on the conenction icon dissapear).
I've found few posts, but didn't find an answer on this. I've tried to reset access points, it didn't help.
I'd be grateful for help.

[Q] Droid 3 CM10.1 No service Problems

I recently installed both AOKP and CM10, the most recent versions on my Verizon Droid 3. Now, i have no service. I downloaded (via wifi) the app "lte on/off" to get a look at what was happening, and the radio keeps rapidly switching on and off, on and off over and over again. This happened with all the AOKP versions i tried and both CM10 versions I tried. Ive rebooted, re-flashed, tried different download links, reflashed again, wipe and reflash. Im at a complete loss here guys, any help would be appreciated. Thanks!

I had the exact same problem. I went insane scouring the web for hours trying to find a single person with the same problem until I finally gave up. Does anyone know the last version that actually worked?
I also have this problem, do anyone have any idea how to fix this problem?

I had similar problems on cm10.1. I have no idea if this will work (I'm outside the US, and my phone asked me to activate the phone), but I also had no service, no data. I changed my network mode from GLOBAL to GSM/WCDMA auto. Now I have service and data (Data after applying the correct carrier apn settings)
I hope this helps you all
P.S. after this step I made factory resets without the need to do the above step again (You only need to put the correct apn settings again if your on networks other than Verizon)

[Q][GSM] restore radio in droid 4

Hi I have a droid 4. I bought it in the USA and used it only in Italy. It was rooted and unlocked and it has always been working fine over GSM and 3G. Then I decided to install CM 10.2.1 and then i upgraded it to CM 11. In both cases sending sms was not working (calls and internet fine). Trying to fix it I went also in the *#*#4636#*#* testing menu and changed setting of radio. But now I cannot restore it and I always get no signal. Both with CM but also booting from Stock ROM.
I flashed many times but still nothing. As first I'd like to have singal back to call and use the net (3G). then I'll fix sms.
Can I do a sort of radio otpion reset? or firmware reset?
Plese help! Thank you!
IF there is some better section (or forum) just tell, I guess it can be a common issue and not specific for D4.

fastboot radio radio.img
I did it too
radio.img is found on the fastboot archive, no data will be lost. enter in fastboot by pressing vol up + down and power
Regards
To make your SMS work, you need to change a setting in build.prop relating to it, none of the radio settings will make it work since that isn't the problem.
ro.telephony.gsm-routes-us-smsc=1 must be changed to ro.telephony.gsm-routes-us-smsc=0
or install mentor's gsm patch

Signal isses

Ok here is my problem, when I am on lte and I lose signal and it moves back to 3g my phone never fully reconnects to data. But if I manually switch to cdma it connects fine to 3g. I have tried to reactivate but it doesn't work well. I think something is seriously wrong with my device.
What software version and firmware version do you currently have installed on your device?
I'm running viper Rom 3.1.0 updated to the lastest firmware. 3.30.651.2.

[Q] T-Mobile lost signal after factory flash 5.1

Hey Guys,
I have seen multiple threads about 5.1 having an issue with SMS/MMS. My problem is that I do not get a signal at all. I did a full factory flash to Android 5.1 and now i get no connection what so ever. I have tried multiple combinations with toggling Enhanced 4G LTE mode and Preferred network type and nothing makes any difference. If I flash back to SOKP rc1 5.0.2 it works great. I have the latest bootloader and radio. Has anyone experenced this or have any tips?
Thank You,
DFL
Have you tried changing your APN? Try these settings https://support.t-mobile.com/docs/DOC-17581 ... Then delete all other APNs you're not using
@YankInDaSouth yeah, i did do that. after much trial and error i got it working. i ended up re-flashing the radio via fastboot, reset and the data/voice cam in.
thank you for the help,
dfl
Glad you got it all worked out!!
611 works for you?
611 not working for me. On stock rooted ROM.

Moto G XT1064 data busted Cyanogen 13.0

Hi guys.
I just rooted and flashed the latest version of cyanogen. But now my data isn't working. Really at a dead end here, don't know what else to do. Here's what I've tried.
-flashed various different roms, including cyanogen 12 and 13. Rebooted stock rom, no difference.
-got APN settings from provider, tried different variations. i'm certain these are correct
-all the obvious things, like rebooting, going into airplane mode, check roaming data
-tried the sim on another model of moto g (first gen) also with cyanogen 13.0. It works fine! so not a sim problem
It's consumer cellular an MVNO bought in VA, used in NY, cyanogen is cm-13.0-20160809-NIGHTLY-titan.
Texting and calling works fine. The baseband version is MSM8626BP_1032.3116.99.00R
Any help appreciated!
This also happened to me too when I flashed cm-13.0-20160806-NIGHTLY-titan.zip on Monday. I've tried everything and data still is not working.
It's bizarre. Absolutely nothing works. With one exception: I tried a T-mobile sim card, non-MVNO, and data started flowing. AT&T does not work, however.
