Take your phone in for service. Trying to transfer the IMEI of a defunct phone to your working phone is illegal, period. No discussion of how to do it is allowed.

IMEI number messed up

Hi,
Let see if someone can help me.
Im trying to help out a friends cousin, he came here to sweden from the war and hes mobile dosent work, so he cant call back home to contact anyone there.
This is what i need help with.
He have a Samsung Galaxy Note 4 SM-N910C and he bought it in turky, to be avaible to use it in hes contry they had to root it in turky (this is what he said) and they rooted it for him.
But the dident seem to leave a backup of the orgininal efs map or anything, have checked the phone storage and even the SDCARD he bought at the same time that he have never formate.
So since the IMEI number is wrong he cant connect to any network here in sweden, the IMEI number goes to some Philips phone.
So i tryed to restore the IMEI to the one on the back of the Note 4 phone, i though i was succsessfull since *#06# shows the right IMEI number now, that match the one on the back.
But when i go into Settings->About Device->Status the IMEI number is still the Philips one, i tryed to recreate and remove the efs folder but ended up with NULL or 000000000 IMEI at Device status.
Can someone help me? me rly wanna be avaible to call home and do video calls with rest of hes family still at home in the war.
I even tryed upgrade firmware and downgrade i have tryed a custom firmware and official.
Tryed changing mode firmware and everthing, been trying to get it to work for 4 days now.
And he dont have any money to buy a box to fix the phone.
Thanks,

As far as I'm aware, transferring IMEI numbers etc is Illegal. This reeks of something illegal.

Greetings,
Changing the IMEI is illegal in most countries and therefore discussing it on XDA is forbidden. I hope you understand.

Serial number for recovery

I have a big issue where my phone will not boot and it will only go to recovery and download mode so I need to do a stock recovery using smart switch but I don't have a Serial Number any Ideas or does anyone have a serial number I could use to be able to recover the phone back to a complete stock or the files to use ODIN?

Why don't you connect with Odin and flash the stock firmware if you have download mode? Easy and all here to read

As I have found both s6 and s7 CDMA versions does not have SN. Maybe you can try to call to your provider or Samsung us, and check it with them? I was not success with them, maybe you more lucky.

i have the same issue, i cant find the SN tryed with samsung and sprint with no success

Same here, I called Samsung and the rep not able to find any info on this Samsung Serial Number. She told me that they don't even use that anymore. She said that they don't even ask for your SN if you need some warranty job done. All you need is the IMEI for all of the newer model phones such as the S7. With that said, I think there seems to be some disconnection between the Smart Switch software and Samsung's new phone identification.

The RS number from the box worked for me.

Null IMEI on Samsung A5

Hi Guys,
This is my first post here and also I am fairly new to android, so I apologize in advance if I violate a forum rule or ask an obvious silly question. Anyway,I Recently, I received a Samsung A5 2016 Dual Sim from my friend which did not boot up. Apparently he had installed an app which caused this situation. Then he had tried to install multiple firmwares with Odin on it without success. Anyway, I received the phone and first strange thing that I found was that product name in download mode was SM-A5108 which was different from A510FD which was on the phones box. This probably was the main reason behind not being able to flash any A510FD firmware on phone. So I flashed a A5108 firmware on it booted up to android. But there was 4 issues there:
1- No baseband version was available.
2- No IMEI information for either of sim card slots and of course not detecting any of sim cards.
3- Very sensible lag and delay on loading apps and working with menus.
4- Also A5108 is apparently available for china region so menu was Chinese and other region specific apps was on it.
I found out the original firmware on it was A510FD so searched a little bit and found out it is possible to restore a backup from A510FD. I downloaded a backup file from internet and restored it using TWRP (Data, System, Boot). After restore, phone booted up with A510FD but once again with null IMEI and also lagging. Right now baseband version is available and device model on about section is A510FD. I know all radio related information is on EFS but I have no EFS backup right now and restoring EFS is not an option. Is there any way to fix IMEI issue now?
I can provide exact build number and any other information about phone and firmwares that I used in case it is required for better troubleshooting.

check you phone model by imei or serial from the box or from back of the phone, if someone messed up that phone is hard to be sure what model is

I forgot to mention there is no IMEI on phone's box or phone itself. But phone's model (A510FD)is printed on box. Also battery is non-removable so not able to check inside of phone for IMEI.

If there is no other option you could remove the back glass panel to see the IMEI number there is a sticker underneath it i replaced the screen of mine and i saw this sticker. You need to be carefull taking off the panel tho cuz you coul rip off the sticker if you're not careful.

Thank you for responding. Okay, Let's suppose I found out IMEI by opening phone's back panel. What is the next step? How could I use these information to recover IMEI to phone? Is there any chance that IMEI information is at EFS partition but due to wrong firmware upgrade it is not working?

Samsung S7 SM-G930F wrong IMEI and model number

Hello guys. I am not quite new here, but I never registered (or I did but I couldn't find with which email or username).
However, I am having some trouble with Samsung S7 phone.
First of all, the IMEI on the About page is not the same as the IMEI on the back of the phone.
When I enter the IMEI from the back of the phone in IMEI checker, I get the right phone (Samsung S7).
When I enter the IMEI from the About page in IMEI checker, I get some old BLU phone.
Second problem is that I think this phone is not duos, however, whichever firmware I try to flash, I see the SIM card manager in the Settings. Which is weird to me.
Third problem is that the phone won't connect to network. I've tried 3 SIM cards (all 3 of those works on other phones), but this one just won't connect.
It shows full strength of signal, it also shows the phone number of the SIM, however, when I try to make a call, it says "Not registered on network".
The phone should not be locked as my brother said that he used it for some time, then he updated it to the latest OS and then did a factory reset. After that, the phone just stopped working.
Does anyone know what could be the issue? Why the IMEIs are different?
I am quite sure that the phone model is SM-G930F, however, the model number in Settings shows SM-G930FD. Which is again weird to me.
I've looked on the Google to see a picture of the SIM card slot of Samsung S7 duos and mine SIM card slot does not like that. Also, on one slot, it says only "microSD" and on another "SIM". So, I guess it is not a duos phone.
Any advices?
Thank you in advance!
All the best,
Dale

It sounds like somebody has changed the IMEI of the phone and patched the certificate for the IMEI to work.
Once you reset the phone or update the firmware on it, it will remove the patched certificate allowing the changed IMEI.
You will need to look for someone that does IMEI repair / change to get it working for you again I know there is a guy on the forums here that does them for free. Look through the s7 edge sub forums for them.

Well, I already flashed the firmware multiple times with different basebands and versions of the firmware as I thought that the firmware is wrong. Also tried to flash the firmware with Phone EFS Clear option checked in Odin.
Everything else on the phone works.

Sorry that this isnt help but you not alone, I unbricked a Samsung S7 (SM-G930F) after it suddenly just bricked (hard brick/soft brick - same thing). Eventually when I installed nougat on it, and finally wanted to use the phone, i tried a simcard and noticed how it would load all saved contacts but whatever I dailed, it responded "Not registered to network". Checking the model number it is now SM-G930FD but i am unable to verify the imei becuase of missing box. I tried many firmwares (even those that specify its for SM-G930F) but the model number remains SM-G930FD.
could any help plz be posted...
