no cellular network - Nexus 6 Q&A, Help & Troubleshooting

Hi there:
I had a rooted nexus 6 with Android 6.
I was playing with chmod and root and messed up some system permissions.
I have re-installed several Nexus 6 Google images 5.1 6.0 etc...
I have everything except cellular signal. It says no service and sometimes no sim card.
I have taken my sim and put it in another phone and it worked.
When I go to *#*#4636#*#*
It says GSM: emergency service only and GPRS service: disconnected.
I tried to change the network type to GSM only and others with no success.
Any help to further diagnose this would be appreciated..
Thanks

Very good point.
When I flashed 6.0.1
under cellular network settings , I only see Data raoming, Preferred network type and System select.
no APN settings
When I re-flashed 5.0.1 , I could see the apn settings, but when I go to it, it says something like that the user doesn't have permission to view the settings. I even tried to add a new settings and save it, but the message stayed there and I see no APN list at all..
I might have messed up the APN permissions with chmod, but I would think a system re-flash would have corrected it..
Thanks

Does your IMEI match the number on your SIM card tray?

HELP. Disconnected because service is unavailable

Since ive installed Maximus 42.0.0 I get not internet on my phone, in the mobile data section it only shows as Disconnected bcause service is unavailable, Ive tried 2 different sim cards, It wont let me try to change to APN settings, Ive tried to reinstall maximus 42 and going back to a really old backup I had of a completely different rom and still nothing, and even after re installing maximus and using a old backup I can never change the APN settings, and it always shows up the top the sim card icon with a !, But it still alerts me on both roms when I eject the SIM card.
I cant find anything that helps, Ive also tried install a new radio and firmware.

Have you tried Settings -> Mobile Data -> Mobile Network Settings -> Access Point Names -> APNs select the Menu (three dots) choose New APN. You can enter all the relevant information there.

Wow, something has messed with your phone. Assuming Maximus downloaded correctly and you checked it MD5 to verify, then maybe your recovery may be causing some issues. Some versions of TWRP are writing in the wrong partition and resulting in missing OS, etc. This version might help. If this doesn't help, then you might have to go back to the stock rom to check if the issue is there. If it is, then you might have to send in your phone for servicing.

I've tried installing it with twrp and clockwork, I used twrp first and that's when it happened but clockwork still installs and se problem. But I was thinking the best thing would be to go right back to stock

I would give the different version of TWRP a try first, then if it failed, I'd go back to stock. It may save you some time and steps.

Go ahead and try this, but first you might want to make sure you have your correct imei.
If not look on the back of your phone, or on the phone box.

why not just writing down your apn on paper? It will take 2 minutes

[Q] data connection issue since lollipop update

Hi All,
Wondering if you can help, since I updated my moto g 2nd gen with the latest update I cannot get a data connection, I have done a factory reset but still nothing. Checked my APN settings and they are correct. I have had a look on google and there does appear to be users with the same issue but no real fix that I can see other than changing it to a different sim slot but only one sim slot works on my device so I cant even test it! Any other ideas or has anybody else had this issue?
Thanks
delete all APN ... reboot test...if the phone didn't autoconfig the APN, you do it.
SS yours APN config before deleted... and check if the parameter of APN is correct by google in it....

Xiaomi Mi 5 - access point settings issue - no mobile data

Hi,
My provider upgraded their network and sent me a new sim card.
With the new sim card I can only call and text, but there is no data - I cannot connect to the internet (only wifi).
I called the provider and we tried to manually set the Access Point Name (APN), but we failed.
In the APNs settings I see the following message: "Access Point Name setting are not available for this user".
When I try to edit access point (3 dots and +) and try to save the new settings, it also fails - there is no profile/access point name.
I did the following:
factory reset
updated TWRP
updated my firmware to the latest Dev version
flashed the latest LOS again (I had the latest update before)
It didn't help. Still no data, still cannot edit the APNs.
Can you edit the APNs on your phones? Any suggestions?
Well, in our country; we make our APN mods as - - - name: your sim card provider's name and Apn is internet. And Apn protocol is IPv4/IPv6 - - - use it like that and send me message if it has gone worked or not

I cannot edit the APN - that's the problem. When I try to add the APN and save it, nothing is being saved.
Btw
My phone is not rooted.
So you can make new apn?

No I cannot.
In Access point names settings I see:
"Access Point Name setting are not available for this user"
When I click "+" I see edit access point. I can edit name, apn, proxy ect, but when I click save, nothing is being saved.
Hmm... Interesting... I have never seen such a bug... So... Can you recover your data, video and your photos and reset your phone to the factory settings?

As I mentioned in my first post I did the following:
factory reset
updated TWRP
updated my firmware to the latest Dev version
flashed the latest LOS again (I had the latest update before)
I also flashed the previous LOS built. Still the same.

I did. I believe that it's the problem of my handset.
I tried the sim card in a different phone and it was working.
My operator also reset my account and disabled and enabled mobile data for it, did some other tests and it's still not working.
My problem is that the "access points name" settings are not available on my phone!!!
Hi, did you ever resolve the issue or find a fix? I'm having the same issue now. Thanks
