IMEI & Operator issue after a regular update to CyanogenMod 12.0 YNG1TAS213

Hi friends,
I am from Turkey and I got a Oneplus One 16GB from a friend, yesterday.
The phone was running on kitkat 4.4.x by then (probably CM11s bıt not sure). I inserted my sim card which worked fine. Checked the registration status of IMEI online which showed that it was registered. Means both IMEI and Operater were working by then.
Then I connected the phone to the internet and checked for the updates that were available. The phone automatically downloaded and installed the updates without any flashing or other intervention. Right now it is running CM 12.0 YNG1TAS213.
However, after the update, I was unable to connect to the operator. Apparently, the phone was continuously trying to connect to the operator and something was stopping it. I tried to figure out why and found the following things.
When phone is on airplane mode or without simcard, it shows the correct IMEI.
When I insert the sim card and check for the IMEI, it shows just an empty box.
I think there is some software bug that is creating a conflict between the IMEI and the sim card.
The forum won't allow posting pictures but you can check them: postimg.org/gallery/1ldxgm1ms/768d9afa/
What are the possible reasons and how can I solve this problem? By downgrading to CM11 or anything else?
Thanks.

Did you make sure it wasn't stolen?
Please help .... I have a similar problem.
The SIM card it is inserted in the phone, but the phone still writes: Please insert SIM card
The SIM card is new and in the other device is functional.
Please help .... I have a similar problem. Writes that: No SIM card plugged in.
Please help
try checking csc via phone info.
Any fix to this?? I've just gotten the same problem on mine! Thought it might have reverted back to the region lock as I am now using a USA sim card and started off with a UK sim card. Just ordered a new UK Sim to see if inserting that one will fix the issue
Please .... Solution
Same problem here... No sim card.

I had this issue with my first Galaxy S6... I went into the three shop and checked my sim and that worked with another phone, but my phone would not accept any other SIM card. I was told to send to Samsung for repair, luckily I was in my 30 day amazon exchange period so I just sent back to supplier and bought a new one.
Same poblem here.. When i insert sim card, the phone restart and when enter in Android show message... "Error occurred while unlocking network... Network unlock code block".... Its a Japan Docomo network.. U think that can resolve it with a subsidy code? To unlock a sim?
Solution needed urgent
Hello everyone till now their is no solution anyone can help plz reply,
i tried to unlock by z3x box pro, octopus box and spt box with no solution, even try to change CSC, rooting, reflashing the same problem still!!! . any solution?????

S7 says OS was modified without authorization?

Hi everybody,
my S7 doesn't want to turn on WiFi anymore, and don't know why. Checking my software version in searching for a clue, I tapped update OS and got the message that my OS was modified without authorization. I rooted some other smartphones in my earlier years (HTC) but not this one, I just have it for some 6 weeks. Did something like that occur to anyone of you?
I attached a screenshot of my softwareinfo if it helps.
Thank you in advance for any hint.
Might Be a software bug, try factory resetting. The important thing is that KNOX isn't tripped, you could always bring it to a Samsung Store and let them update it for free.
Y just try factory reset or installing a stock rom with odin again otherwhise go back to the store!
goodluck!
I did factory reset, and the problem was gone - for a short while. I also switched off auto update of fear of wrong OTA updates. Now, my OS doesn't appear as unauthorized altered. But the moment I inserted the second SIM (sorry, forgot to mention it's the dual SIM Version) the initial problem reappeard: No wifi connectivity. Is the wifi module located near the SIM Slots?
Cause of error found
Just wanted to inform you, that I succeeded in finding the source of wifi error: Using the second SIM slot (only with SIM, SD card working fine) disables wifi. Why exactly, I couldn't find out though... Anyone experienced something similar?

Lost 4G(LTE) connectivity after latest official update

Hello guys,
I am losing my mind here so I kindly ask for help. I aint no expert in flashing roms or anything, I have a stock Redmi 6 and yesterday I got a pop up about updating my phone. I selected yes and my nightmare begins.
Since then, I cant get the phone to connect via mobile network. I cant get any connectivity of any type using mobile data.
The phone is a Redmi 6, android version is 8.1.0 O11019 and rom is MIUI Global 10.2 Stable 10.2.3.0 (OCGMIXM).
Please help the noob get his phone back, I am about to throw it away
There is an update miui_HM6Global_V10.2.4.0.OCGMIXM_f662ddbe15_8.1.zip
http://ru.miui.com/thread-24171-1-1.html
thanks for your reply, updating to 10.2.4.0.OCGMIXM didnt resolve the issue.
Still no 4G.
Any other ideas? Please I am desperate
Head to" about phone" (in settings ) tap " internal storage " multiple times to enter phone info
Then head over to change network settings to LTE only or enable one with LTE as a possible option if you've disabled it by mistake
Also check which slot your sim is in ...
May not work if sim is in secondary slot and 4g is disabled for it
Let me know if it worked !
Cheers !
Thank you for your reply my friend.
I have tried all these things, they were the obvious ones, so I went with them first. Nothing works, phone is unable to connect to 4G. I have flashed multiple times in case it was a bad flash, I even downgraded to a Developers Rom, but nothing works.
Funniest thing of all, I contacted Xiaomi UK customer services today, and after trying various *# codes, and the guy asking me to turn the phone off and then on again, he ended up saying that I need to wait for the next update.
It is insane

Samsung Galaxy S10 (SM-G973F) doesn't register to network

I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C

How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.
