Hi
So I bought this phone used.
I put sim card .. the phone shows the Carrier, even shows the APN settings . But I can't make calls (emergency calls only)
The imie of the device found on back is For Factory Unlocked 928A and I contacted ATT and confirm it's unlocked.
The Problem is : when you dial *# 06 # the phone shows a different imei number. And this particular number when looked up doesn't belong to any device on Earth. Using imei checker. And when going to service mode it shows imei: NG
So.
The first step on solution is to restore the original imei number that belongs to the device . That's logic right ?
How can I?
What about efs partition ?
I am on latest Nougat. Can't downgrade to 5.1.1 to root and try to change imei or restore efs
Trying downgrade in Odin give FAIL lol
What to do ? Excuse my English.

I want my phone to work with a celular 1 chip and the unlock code that was giving to me from " T mobile" does NOT work .. I was told to give them my Imei number I did so and the code that was giving back to me does NOT work
The IMEI : 350314010484948
Sim unlock reference :0665527
Unlock code : 89520329
it does Not work. I can NOT get the IMEI number for the celular 1 chip because it will not open . [email protected]
PLEASE HELP ME

You can use xdaunlock or if that doesnt work you could try the special edition rom. How did you get the imei number, if you got it from the label, try entering *#06# from the telephone keypad and see if that number matches the label.
Hi!
Problems:
1) Serial is 000000000000000, although IMEI and IMEI/SV is ok.
2) Out of service network state, although network is detectable.
Solution:
Ariza Patch.
I know I've given the solution, but everytime I have to reinstall a ROM I have to do this over and over again which bothers me, besides having a serial number is better than 000000000.
The thing that caused this was a google app named swapper. I believe it stored the swap file on the partition of the EFS.
The phone's EFS was fixed by some technician, but unfortunately the serial was not.
No, I do not have a backup of EFS to restore. I only figured that out after this happened.
Other apps used to diagnose:
Check FUS - it says on "Product Code" as "Not Active"
CSC Select - played with a bunch of CSC codes to change, still no luck.
Galaxsim - shows my real serial number but phone is already unlocked.
Any suggestions would really be helpful aside from sending it back to Samsung Service Center and restoring a backed up EFS which I apparently don't have.
Thank you!
Ive this problem too

Hi,
I had an OTA update from 4.2.2 to 4.3 and some days after that, when I was using google maps while on roaming network, my phone stopped getting signal from carrier. Since then, I have followed many posts on xda and did these things using NRT (Nexus Root Toolkit):-
1. Unlock
2. Flash + Unroot
But, after doing all these, my phone still does not get the signal. The current problem (I'm not a very technical person):-
1. About Phone --> Status (copying only those properties which might be relevant):-
Network: Unknown
Signal strenght: 0 dBm 99asu
Mobile network type: UNKNOWN:0
Service state: Out of service or Radio Off (this keeps on toggling every few seconds)
IMEI: UNKNOWN
IMEI SV: UNKNOWN
Serial Number: <some number>
2. Phone info available in *#*#4636#*#*:-
Set preferred network type: Unknown
Turn On Radio or Turn Off Radio (This keeps toggling every few seconds)
Actually, after reading so many posts on xda, I can conclude that the efs partition is lost. If I'm goig in the right direction to pin point the problem, please let me know where I can download EFS and change it to point it to my Phone's IMEI.
Will the above step solve this problem ?
Any help is much appreciated.

If you have a Nandroid Backup, just restore it. Ur signal will be back.
If ur EFS is gone, U'll have to do one more step. This thread might help you. I had the same problem (IMEI lost) and fixed my phone by doing this http://forum.xda-developers.com/showpost.php?p=47045295&postcount=6

Actually, I don't have a Nandroid backup.
And, the steps mentioned in the link you provided also do Not tell about how to fix an unknown IMEI
PS: I dont have a generic IMEI now. My IMEI as seen from *#06# is empty. *#06# shows IMEI (but no IMEI number next to it) and then an OK button.
Hi. I tried to change my IMEI number using the Chamelephon app. It did work, but it didn't turn out great. Network functions are okay, but it needs constant network operator scan as soon as I turn on airplane mode or restart my phone. The IMEI number became random numbers and symbols.
IMEI 1: >8<4=<:7?7<6?:2
IMEI 2: 9><398?64><6086
EFS is fine. Only IMEI has a defect.
I realized that Chamelephon should only be used on MTK (chinese or cloned) devices. Now I can't seem to find a way to get it back. Can someone teach me how, and do I need to get any Samsung Tool Pro type of things? If yes, how do I get started? (btw I want to do this for free)
Hello all
I'm using a Redmi Note 8 pro with the latest Android 10 update.
I was having network issues so I entered into test mode and just ran ping test a couple of times.
Then the page said that in order to change the settings you must reboot and I did. After that my phone stopped showing the second SIM card.
I went to test mode again but phone information 2 was missing.
I checked my IMEI number from the dialer by entering *#06#
I can see only one IMEI number being displayed, the IMEI number of the second SIM slot is missing.
I tried to input it manually using MTK Enginner mode but the CDS information option under connectivity settings is missing.
I've not rooted the phone or ever unlocked the bootloader
Below are a few screenshots.
I'm in a very terrible condition as service centres near me are all closed due to Covid 19 lockdown
Can anyone help me out regarding this problem and tell me a fix ???
IMEI : https://drive.google.com/file/d/1Hhya6vVdH5VjY2OVV2XUyXMex7Nt6-cV/view?usp=drivesdk
Software Information (IMEI) : https://drive.google.com/file/d/1HdVmd82XER7KZ2KbTbOt42a_TqLH0Gft/view?usp=drivesdk
Testing mode settings : https://drive.google.com/file/d/1HsTb7fsyPCWLr2C4eeVwhp1ya811a32t/view?usp=drivesdk
A factory data reset did the job and the phone now shows both SIM cards.
Everything running perfect now
