My Samsung Galaxy S5 is showing IMEI null. How can I recover it? My phone is not registering the network anymore.
Please help me out!!
Take it to the repair store to get fixed if you didn't back up your EFS partition
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.
How can I recover "UNKNOWN" and "NULL/NULL" Base Band & IMEI on Note3 SM-N900A
I sold a Samsung Galaxy Note 3 SM-N900A to someone online. The LCD was bad so I did a hard reset of the phone but forgot to remove my google account. The person who bought the phone installed a new LCD but was locked out. So instead of contacting me to help, they decided to try and root the phone. but they did not back up any files and erased the EFS file and lost the IMEI number and Base Band. This person then returned the phone back to me claiming it doesn't work and they removed the LCD possibly so I couldn't see what they did. I purchased a new LCD so I could refurbish it but once I turned it on it powered up and showed me a pad lock unlocked logo underneath it said custom. after it loaded in the settings under about device I noticed base band saying UNKNOWN, IMEI was also saying UNKNOWN so I dialed *#06# and that said "null/null" I used Odin and the 4.4.2 stock rom to flash the firmware everything went smooth and no more padlock saying custom.... however the imei and base band are still saying UNKNOWN. any help to get this back on track so I can use it would be great. I am not a noob but I am also no expert so please provide instruction if you can assist me. thank you in advance...!!!
Google search ? Xda search ?
Step one restore your backed up EFS folder.
Baseband flash via Odin. See multiple identical posts .

there are no EFS files to restore from. I don't think the phone was rooted I think it was just a custom ROM installed but they didn't back anything up. I have never rooted or jailbroken a phone I used Odin twice. once to flash a G-s2 and to install the OEM firmware for this phone. I need to know the process on how to restore the lost IMEI and baseband These steps I don't know where to start. I see people fixing this problem but do not see clear instructions to follow. I am good at fixing computer hardware and software but phone repair I am new to.
Lost IMEI service center repair .
Baseband see thread in General section .

Where did you get 4.4.2 since AT&T never released a full Odin firmware flash.

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...
It can be done by repair IMEI, i would like to help you if you'r interested

My sister brought her s8+ phone to Vietnam & tries to unlock it but now she's back in the state & she cannot use the phone so when I looked at it, the Imei is all 0. I went & update from android 8 to 9 using the TMB official firmware but still didn't work. I've been Google but unable to find any solution that work. I've tried to go into the field test mode but it's not available. Any idea how I can restore the imei?

I found the box with original IMEI, is there a tool for me to update the IMEI? TIA
EFS backup if you have. If you don't you will have to pay someone with service box to write new imei to your device. You won't be able to use the one that is on the box. At lease that was the case for me 2 years ago.
Not sure, all I know is how to access the IDEI
These imei are cert based if you ruined the efs they are cert based a paid service is the only way which we do not discuss on xda

Is there a way to see if a backup is created on the phone?
If you made it through recovery or have root and use 3rd party app before the unlock.
