This handset was absolutely fine until it updated to Nougat then it wouldnt sign onto the network. It see's the network fine, just wont ever register on it. Sometimes shows a signal bar but emergency calls only, other times a circle with a 45 degree line through it. I have tried multiple roms and all the same, I should add that Secure Boot is enabled and since it updated to 7.0 I cannot downgrade back again. I have checked the phone hasn't been blacklisted, all comes back clean.
Can anyone help? It works fine apart from this unable to connect to network, try later problem.
Thanks in advance

Heyho,
about three weeks ago, my N5 suddenly lost it's signal over night and shows me "Emergency calls only" and it won't register into any network, just giving "Selected network unavailable".
When this occured my N5 had 4.4.2 stock ROM and rooted. I've unrooted it and updated to 4.4.4, but I still got the same problem.
Problem occurs with any simcard, while simcard works with other phones just fine.
Have deleted and reconfigured APN, but didn't make any difference.
I get a signal every few days, but I still can't receive text/calls or call/text anyone and my mobile data doesn't work.
I even tried to downgrade to 4.4, but that didn't solve my problem either...
I'm from Germany, but in New Zealand at the moment, so I really need my phone in case of emergencies and to stay in touch with family/friends.
I have been searching for a solution since it started, but have not been able to find anything that worked.
Sending it back to Google isn't an option right now because I am travelling.
I am really thankfull for any suggestions or if anyone knows how to fix this problem!
Cheers
Have you checked to make sure the network setting says 2g/3g/LTE preferred. Because I had this problem when it was switched to 2g only and was fixed by the above option
If the above fails trying going to your dialer and typing *#*#4636#*#*. Go into phone information and you should see a drop down box to select your network mode. Play around with those until you get a signal but you might not want to try CDMA options (WCDMA is ok) since you're on a GSM network.
Sent from my Nexus 5 using XDA Free mobile app
had exactly the same issue as you mentioned. Nexus 5 tends to lose network without any logical explanation and it tends to work at one place but stop showing network if you walk half a mile down the road (or may not show any network anywhere). Google has released an update in June in which they have updated the modem to solve the problem..given that I am in India and the June update was for India, Australia and Newzeland, it worked like a charm for me (all i had to do was flash the modem from twrp)..people as far away as netherlands have reported the modem to work for them..
NOTE: IF U INTEND TO FLASH THE LATEST MODEM, DO NOT FORGET TO TAKE A BACKUP OF YOUR CURRENT MODEM PRIOR TO FLASHING THE NEW ONE..
check your sim card. if you can, try someone elses.
Alright,
I've tried every thing again so far, but nothing seems to work.
Sitting in the library, I noticed that I get a signal, when connected to WiFi, which stays for 1-2 hours after disconnecting.
But I still can't make any calls or text and mobile data doesn't work though the APN is correctly configured and and data enabled.
I really hope to be able to solve this problem somehow, don't want to put aside my beloved N5 :/

Edit: Haven't found any solution so far and bought a new phone for the moment until I'm able to send it back to Google.
Might be an hardware issue and not software related.

Hi all.
I bought an s6 last week (G920F) and am running it on the 3 UK network.
Since getting it the phone will randomly show my location a Cheltenham in the UK, when I'm in fact in Sunderland, c.200+ miles away.
At home on wifi its fine but at work 10 miles away it often shows the wrong location (but when wrong its always Cheltenham).
At times it works ok. I`ve tried going from airplane mode to back and blocking/restarting mobile data and switching off handset and it does seem to eventually change but I cant pinpoint what 'fixes` it. I have tried a full factory reset which hasn't made any difference, but I dont know if this issue is software, handset or just network related....but I know it didnt happen with my 3 UK s4 before I changed.
I do have Location enabled but just on the Network and Wifi setting as I dont want to flatten the battery with GPS.
Anyone have any clues guys ?
Thanks
Robin
Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!
If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.
Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged
Randomly, earlier today my Galaxy S7 went from having signal fine to being unable to successfully connect to a network.
The problem is not the SIM, as I tried my SIM in another phone (fine) and a working SIM in mine (no luck). I even tried a different network but no luck.
The problem survives a reboot, and I tried resetting the network settings. I also tried clearing the cache partition. I haven't yet tried a full factory restore.
I'm on the latest S7 firmware - I'm a beta user for the Android 7 firmware.
Anyone had this issue and know a fix? It could be hardware but I'd find that a bit odd... I suspect something software is going on, as it detects the SIM fine, and shows a signal that fluctuates, it just seems unable to connect properly...
Thanks!
Resolved... turns out the phone I got 2 months ago (from CEX) had since been blacklisted - and it kicked in yesterday. I took it back to them, they're raging but I got a replacement!
I recently acquired a Permanently Unlocked US T-Mobile Galaxy s7 SM-G930T. Since I have Verizon, I flashed it to the latest Verizon Firmware SM-G930V from sammobile using the latest Odin. Everything went perfect.
The only problem is that the wifi will not stay connected.
It will connect for a few minutes at a time, and then, despite it saying it is still connected to wifi, videos will suddenly not load, apps will not open. I run a speed test and then it will show the little exclamation mark on my wifi signal, only then showing that wifi is not connect or having problems. It's very tedious as I go based off the wifi signal to and since it says it's connected i am missing important notifications despite my mobile data being connected. I have unlimited data with my carrier so i could simply stay connected to mobile data at all times, but i would like to have my wifi working again. Does anybody know what may be causing this problem.
I tried flashing it back to T-Mobile. and once again everything works perfect. except for the wifi. So i believe it may have to do with the firmware, or maybe i need another file or files that i still need to install? I have been researching it for a week and i just can not figure out a solution.
I tried resetting my router, nothing.
Different older firmwares for Verizon from Sammobile, nothing.
Resetting Cache in recovery mode, nothing.
Unchecking Smart switch (function for it to switch between mobile and wifi automatically), nothing.
Unchecked Wifi and bluetooth scanning, nothing.
Can somebody please help?
Just asking, what were the bootloader versions of the T-Mobile and Verizon ROM's you went back and forth with? *Bootloader version can be found in baseband number i.e SM-930TUVS4CRL1, The 4 is the BL.
