Seems to be a similar issue like here: [Q]Null Imei, Baseband Unknown N7105 by Emprt.
With a "broken" EFS partition.
Check this thread: Baseband Unknown and IMEI Null NOW WORKING by karlonicolas.
Maybe this will work in your case too.
Sometimes reflashing the modem/baseband can help to get back the correct IMEI.
And for the next time, please backup your EFS partition like described here: [WARNING! + GUIDE] Backup and Restore IMEI / NV Data Procedure for GT-I9305 by lyriquidperfection.
Good luck !
Thread closed. Thank you!
After installing a custom ROM on my galaxy s6 it would no longer recognize my SIM card. I did wipe every option in TWRP recovery before flashing the ROM which might have something to do with the issue. The phone states "No SIM Card - No Service" in the top left of the lock screen, it also wont let me call any numbers to edit things in the phone. I have done some research and it sounds like I have wiped the sim and lost the IMEI/EFS data and therefore no longer have access to my sim. I was wondering if there was any possible fix or should I just send it off to Samsung to get repaired?
Did you back up the EFS partition, and put it somewhere safe? If not, you have a paperweight.
Repair won't be covered under warranty.

Unfortunately I didn't back up the EFS partition. Situation is looking bad. :l
Try dialnig *#06# and see does it shows IMEI and sn, alo try *#0011# select stack 1 and check whether IMEI is OK, or NG.
Also what does it say in phone settings under baseband? Do you have mobile networks menu in settings?
You can try Smart Switch emergency initialization with sn of the phone if IMEI is ok (it will install latest stock fw for your phone) and see if that helps.
When I typed in "*#06#" The SN number was shown however the IMEI number was not. When I typed in "*#0011#" There was nothing but blank spaces separated by grey lines, I tried selecting row 1 however nothing happened. My base band version is "Unknown" listed under settings. I do however have the network settings listed in settings. In Smart Switch when I try to run the device initialization it states that my s6 "doesn't support initialising". I have flashed three different downloads of the stock rom to my phone using ODIN and have had no luck with any of them.
well Smart Switch always says that S6 is not supported, but initialization can be done anyway, just dont connect the phone until it asks you to do so, instructions below:
http://forum.xda-developers.com/galaxy-s6/help/how-to-smart-switch-emergency-t3383448
What is your model anyway, do you know which region fw was originaly on the phone, and which sv rev is shown in the download mode?
does in recovery mode says anything about DRK?
Unfortunately Smart Switch says that "'SM-G920F' does not support initialing. Please contact out service center." Even when I have entered the correct S/N and device model, as well as not plugging in the phone. My device model is the SM-G920F. I don't know the original region FW that was originally on the phone, however it was purchased in the UK and that is where I am have been ever since I bought the phone. The SWREV is: "B:3 K:2 S:2" in download mode. I currently have TWRP recovery installed so is there a place for me to search for the DRK in TWRP? Or should I re-flash the stock recovery using Odin?
that is weird, I reinitialized my g920f many times without any issue. DRK error is usually shown in stock recovery. does the phone boots up with stock fw, and are you using any custom kernel?
i got the same problem when I flashed xtrolite and alexis custom ROM on my S6, both ROM after flashing I got no service.
But I did a full stock backup in TWRP.
baseband unknown means that there is a problem with modem part of fw. and I dont know what fw you flashed. you said that you tried to flash stock, but it doesn`t work, but a little more details would maybe make a difference, like which fw, and what exactly is happening, what does about the phone menu says.
So far, since baseband is unknown I would try to flash modem fw with odin (for exact fw that is in the phone). before that usb settings should be set to CP, by dialing *#0808#
or if you decide tu run custom fw, you can always try asking in that rom thread, maybe someone already had issues like that with that rom and fixed them, or the developer of that rom can help fix it.
Boot your s6 to download and flash stock rom via odin from samsung it maybe work
I have a Cricket branded galaxy s6 on the Cricket network and I was having some issues with the fingerprint reader which led to an eventual factory reset after trying many other things and of course I forgot to turn off reactivation lock beforehand. When booting back up I realized my Samsung account wouldn't sync up and I realized what I had done and after trying numerous things to fix that problem it led to me flashing the firmware for my phone and of course I didn't make a copy of the efs folder. So now my phone cannot connect to any network because the IMEI number is showing as unknown and so is the sim card status. So my question is... Is there anything I can do now to regain network connectivity?
If you are rooted you may restore nv_data.bak and nv_core.bak, that may get your IMEI back, if not, you can purchase a new and clean CERT file to get a new authentic IMEI back.
Would the phone have to have been rooted before deleting the IMEI number? I still have the original IMEI number written down as well
Dear XDA members,
this is my first post, so please be a bit patient if I do something wrong
I got a very stubborn phone from some relative - he complained that sometimes the voice is fading during voice call. Otherwise the phone was working flawlessly, no other issues/trouble, was working across Europe. It was imported to Europe from Asia, which seems to have some importance, but we'll get there.
When I got it, the first thing I tried was OTA update - however there was some error (it still had 5.11 version back in December 2018). Not thinking too much (and not being aware about CSC codes) I got Odin and flashed it with 7.0 stock firmware. At first moment everything seemed fine, but after some time I inserted my SIM-card and I noticed that phone can't register to mobile network - then I tried another SIM-card from another carrier and result was the same. I tried to flash with few another ROMs with different CSC codes - but the result was exactly the same.
The IMEI and serial numbers reported by phone were in line with info on sticker and engraving on the back cover, but then I found that *#0011# shows IMEI Status: NG.
Wondering if the phone is not black listed I checked it's IMEI at imei.info web site and to my surprise it reported different Samsung serial number than the one on back sticker/cover! I opened back cover and I found that the phone has been manipulated, there's no sticker on the battery with phone info, but is some "Chinese" OK sticker...
I searched the XDA-forum and tried various fixes:
1) deleting nv_data from /efs partition in order to restore factory IMEI, etc., (https://forum.xda-developers.com/showpost.php?p=75927733&postcount=37),
2) flashing with combination firmware (https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516 tried both A and B methods),
3) downgrading to 5.1.1,
4) HEX editing efs partition backup to change Samsung serial number to the one reported by imei.info - I replaced sn in three places, phone reports "edited" sn, but I have no clue if it's not causing any checksum errors, I still have "original" backup,
5) repeating 1,2,3 with "new serial number",
6) installing NexusOS-9.
None of the above made it possible to connect to mobile network, checking with *#0011# after each of the above (except for NexusOS) still shows IMEI: NG
Is there any other way that could help that issue? What does IMEI: NG actually mean?
I checked with some phone repair shops, and none of them seemed to be equipped with Z3X-toolbox, at one place I heard that they can try to fix it, but give no guarantee of success, since the phone looks to be non-original.
As I wrote at the beginning - non-original or refurbished in Asia, the phone worked without any issues in few European countries, so I assume that IMEI is not black listed anywhere.
Thank you in advance for any guidance!

So I have 2 phones (both S7e), but one lost its IMEI / having "can't mount /efs" problem. This phone unluckily doesn't have a back up of its own EFS / IMEI digitally, but it still has the phone sticker that has its associated IMEI. Now, my plan was to TWRP restore a backup from the working phone to the unusable one so that I can fix the EFS problem and right after, "edit" the IMEI number to what it's supposed to according to the sticker left on the phone.
My questions are:
1) is this possible?
2) if so, can someone help me find out the proper steps/tools to help me change the IMEI on the 2nd phone with the temporarily duplicated IMEI
3) any tips on making sure I don't have both phones running and get blacklisted for having 2 phones with the same IMEI on i was thinking just to leave both phones on airplane mode or at the very least, turn off the first phone until I get the second phone working
