Mobile Status disconnected - Nexus 5 Q&A, Help & Troubleshooting

Hello all
I've been experiencing a problem which has been occurring for the past two months and it's driving me crazy.
My Nexus 5 phone rarely receives or can make calls but data (web browsing etc) works fine. My provider has not been able to fix the problem on their end and I believe this is a bug related to the phone on a software level.
I saw that this problem might be related to the radio version and a possible bug with Kitkat (4.4.4) so I flashed several radio img but that didn't help either.
My build number is KTU84P and Radio img KRT16m. I am running a stock img rom with an unlocked boot loader and recovery.
Please advise what I can do or try.

I noticed with this radio band (KR16m) that my mobile network state moves to connected and calls can be made and received when WIFI is off. As soon as I turn WIFI on, the mobile network states moves to disconnect and I loose calls/receive ability.
I've seen posts with a similar problem but I could not find a solution. Maybe downgrade the build entirely to 4.4.2 or lower?
thanks

[Q] Help! Wifi won't turn on after otherwise successful root/custom rom

Samsung Nexus S I9023 (Australian stock)
Baseband version I9020XXKI1 (from bootloader screen)
Baseband version I9023XXKI1 (from System Settings>About phone)
Bootloader version I9020XXKL1 (from bootloader screen)
Kernel version 3.0.8-g6656123
I have been using my Nexus S I9023 with official OTA 4.0.4 (and 4.0.3 before update) with no wifi or network problems. Yesterday however I decided to unlock bootloader, gain root access and flash a custom rom for performance/battery life purposes. I flashed CyberGR-MOD v.11 with the stock kernel and radio with CWM, with no other add-ons flashed.
It went well except for the fact that wifi has not been able to turn on since the first reboot. The switch will attempt to slide to 'On' but flickers, and hangs on 'Turning Wi-Fi on..' It makes no difference whether the SIM is inserted or not, Wi-Fi just does not turn on. Under 'Advanced' WiFi settings, WiFi MAC address and IP address are both Unavailable.
I have been searching for fixes for the last day, such as the WiFix apk found on this thread (http://forum.xda-developers.com/showthread.php?t=1445766) but nothing has worked. I have tried flashing other ROMs, reverting to stock OTA 4.0.3 and relocking the bootloader to return the phone to stock, but WiFi will not turn on in any configuration.
Portable WiFi hotspot also will not work, with merely 'Error' being reported when I try to turn it on.
Is the disparity between bootloader/phone stats regarding baseband version an indicator that I flashed incorrectly? Is it a radio problem?
Would greatly appreciate some speedy responses as I cannot seem to find any solutions to this particular problem.
[EDIT] Fixed problem by installing new kernel, was not able to do this before as my version of CWM was bugged and required an update. From then on was able to flash new files, kernel was the answer!

Radio connection loop in 3.0 baseband modems

Hello! I now move on to new cyanogen roms but since the firmware is updated new baseband is "di 3.0".
I have a oneplus one which its IMEI changed by changing 00550 NV ITEM. Since oneplus one has its own security policy about changing IMEI my 2G not working yet I can able to run 3G in 2.0 modems ( Kitkat Modems ) (My country doesn't have 4G btw).
Since I installed a new rom with a new firmware my reception run into connection loop which is connecting and instantly drop the connection says no sim card. Since its in a loop it tries to connect over and over and drops.
I can easly save this by flashing any kitkat modem, connection become stable but it breaks gyro sensors and the sensor fixes in xda won't help the issue..
Is there any way to disable natively disable 2G on DI3.0 basebands ? or is it checking the NV item and breaks the connection ? if it is, is there a way to disable that also ? I Can't use any roms because of this baseband and sensor issue.
Note : I also tried to write its own IMEI again but it is still looping and no 2G in 2.0basebands.

Did you tried clean flash COS12.1 or Color OS.
This usually happens due to incompatible Modem with the firmware, bootloader combination.
I also experienced similar issue sometime back using Sultan's build, which is my primary OS right now.
check this post out and the thread.

And if needed modems separately.
All the best!!
I had the same issue a few months ago with CM13 builds. My TWRP recovery was the problem. Try updaing it to the newest version.
dl.twrp.me/bacon/
i had a similar problem after OTA update to CM13.1. So upset I just waited a few days to calm down then went on here and found how someone said sim issues sometimes just need a new sim card. so i went down to my carrier metropcs and they put in a sim adapter for one thing my sim was nano and needed to be made to fit opo micro slot. then they did a refresh and it was good as if it never happened. cost me 15 bucks but worth it compared to what i thought i was up against.

If your doing using lg flash tool or Referbish flash in LGUP and performed a factory rest from recovery and still have an issue it most definitely sounds like a hardware issue.
Have you tried connecting to a open wifi network or a different wifi network??

I tried 8 wifi network, everytime phone says wifi saved. If it is about hardware, how can i fix this? My phone doesnt have warranty. I buyed this phone in usa and i guess this phone doesnt have a repair service in turkey.
And my phone's imei number is clone, can problem be about this?

If it's hardware you can't unless you take it somewhere to be repaired. You cannot fix hardware without taking apart the device and or replacing a part. If your imei is not original that has nothing to do with WiFi only cellular.

It's a hardware problem. Only fix is usually a board replacement. It's a common problem

Its not a hardware problem because i am facing same problem but my hardware is correct and i started to face this problem after marshmallow update
Problem Solved
I have solved my problem.
This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

Weird Connection Issue - Two AT&T Connections

I'm having a super weird issue with my OPO. No matter what I do (install different OS, flash new modem, complete wipe including formatting drives to a different format type) I keep getting two AT&T connections on my phone. *Can't post image due to post restrictions*
I am using a WIND sim from Canada with roaming in the US. I used to be able to connect to my choice of either AT&T or Tmobile. Now when I try and connect to one of those carriers, it flashes registered on network but then does not change what network it is registered on. I've tried disconnecting from the network and then trying to connect. Nothing! The only network it will let me connect to is that weird extra AT&T network, and all call through it have no caller ID, just says call from AT&T.
Any ideas of what this could be would really help me out. I'm all out of ideas
Update - After uninstalling and re-installing everything I could think of, I am now running on CM11. If I update through OTA to CM13 the problem returns.
Update 2 - In case anyone else encounters this issue, after a whole lot of work, including softbricking my phone, I managed to get it working. You must install TWRP Materialized and install the 44S baseband. No other recovery will work, must be Materialized. After I installed the 44S baseband I updated to Omnirom 6.0 and everything is working great!
