If you're facing issues with mobile connectivity, you can reinstall the modem files, as follows:

1. Download the factory image for your device from http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750

2. Extract NON-HLOS.bin and fsg.mbn to a folder of your choice.

3. Download and install fastboot (or place the executable in the folder where you extracted the files), if not installed.

If you're using Windows you'll need to install the needed drivers

4. In the file manager, navigate to the folder where you extracted the files.

5. Right click > (Actions) > Open terminal (or CMD) here...

6. Reboot to bootloader (hold power and volume down buttons until you can read "AP Fastboot Flash Mode")

7. Type in the following commands:

Code:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn

If it fails, try running the commands with administratives privileges (for Mac and Linux use sudo fastboot instead of fastboot, for Windows right click CMD and open with admin privilege).

8. Reboot your phone (power button)

Cellular Data is still not working

Hi ,

I am new to this forum and have tried your method of flashing only the network related files on Moto G 2015 Osprey, but still the cellular data does not work properly.
I am able to browse the internet but downloads using Google Play Store is not possible using cellular data.
Have tried your method and some others suggested on youtube on the following Roms:
1. AOSCP CypherOs 7.1
2. AOSPExtended 7.0 v1.2
3. AOSPExtended 7.1.1 v2.0
4. GZ Rom Tesla

No issues are seen in the following roms:
1. Stock Marshmallow 6.0.1 (after the update few months ago)
2. Stock Marshmallow optimized rom on xda
3. Nexus Experience Rom 6.0.1 from nxroms.

Kindly suggest a method to get cellular data working for downloads too.

Thanks.

Have you tried contacting your carrier or checking if you didn't disable anything related to mobile network downloads on your Google account?

Hi Henriquefeira,

I am on roaming on all the roms which i have mentioned above. I have not contacted my carrier for any such issues. Also in the roms which are working (both in home and roaming locations), I did not change any settings. They just work out of the box. Even in the roms which have issues, basic browsing works after few reboots to the phone, but downloads from Google Play or even elsewhere just dont happen.

I have tried changing Apn , registering to the wireless carrier etc. in the settings but these changes did not work.
Also a feature which was working out of the box in the previous android versions and custom roms is broken now.

Hope we all get a solution so that 7.1.1 can be used as a daily driver...till then on NxRom 10.4.

Found a link which descibes the issue:https://productforums.google.com/forum/#!topic/nexus/21wGieItCik

Hi all,
For any one who stumbles across this issue....it is indeed a bug in Nougat 7.0, 7.1, 7.1.1 even on the Nexus and Pixel line of phones. It is not a problem specific to any custom rom.Solution is to use alternate app stores: Appbrain, Amazon Appstore, Apkpure,

Thanks to all for their roms and answers.

I did this with the newest Lineage rom and now I face constant reboots. So be warned...
If anyone knows how to fix this, I'm open for suggestions.

Do you have the modem files of the old firmware ? .. i dont want to download a full rom for getting the modem. If you have please upload them here . XT1550_OSPREY_RETASIA_DS_2GB_6.0.1_MPI24.107-55_cid7 is the firmware for which i need the modem.

Hey !

I have a XT1541, completly unlocked with "modem" from Europe. My network is "Free" from France.
I'm in Canada now but only have Edge network. Can I flash modem files from another ROM or is it useless/dangerous ?

Thanks !

After flahed a custom recovery I was in trouble with H+ and 4G connections, just 3G works.
I did what you described and it works fine, but when I turn off the phone the previous problems happen again.
Any suggestion?

Try running just the second and third commands. If the problem persists, check your preferred network type under Settings or under Phone info in the testing menu (dial *#*#4636*#*# to get there).

My brother and I both have an Osprey and I unlocked both device's bootloader in order to flash some good old ROMs but he started toying with the device flashing files he found I don't know where (also don't know why) and now his phone won't connect to 4G.

I've been using RR Oreo on my XT1542 and he was on stock so I though that maybe flashing the same ROM that I'm using on his device the issue would resolve itself but to my surprise it didn't.

What can I do to fix this? The phone is connecting only to 3G networks. I've even tried changing the options using #*#*4636*#*# with no success. If I choose any other option than WCDMA the phone goes to "Emergency calls only"
