Hello everyone, recently I've flashed the Superman ROM V.3.0.1 on my S7 Edge and everything was fine until I went to general settings on my phone and saw my IMEI is now UNKNOWN. I know this thread may be already solved, and yes, these days I was looking for answers for my problem but I need to know for sure what alternatives I have to recover my IMEI. I have to mention, my phone is 100% original, it has its own IMEI from the beginning, not a copy or MTK device. I saw some sollutions based on some kind of programs to restore manually the IMEI with a command, and this method for me it's not like the best thing to do in this situation..
When I am dialing *#06# I receive the following information: " SM-G935F is not supported on showIMEI ".
I've checked through TWRP ( version 3.1.1.0 ) the partition EFS, is still there ( it has 2mb ). What do you guys think about this? Flashing the stock ROM from sammobile may solve my problem? What alternatives do I have?
Thank you!

Hello All,
I am new to rooting phones and recently tried something on a galaxy S2. I had a korean version of S2 model SHW-250s which was locked. I lost my new phone so tried unlocking this myself...looked at some youtube videos some blogs and finally decided to use this method posted by someone:
1)Flash these two files using ODIN to convert the korean model into international version :
GTI9100_ext4.pit
9100XWLPW_I9100ODDLPC_I9100DDLPB_HOME.tar.md5 (stock ICS firmware for my country).
This successfully converted my phone to S2i9100.
2)Then to unlock I used a siyah kernel as posted by a developer :: Siyah-v3.2b8
This successfully installed SU and i checked using RootChecker apps that there is root access.
3)Then to unlock my phone i used GalaxSimUnlock app (did rooting as this app required root access)
This successfully unlocked my phone. I was able to call receive messages with new carrier.
I installed some more general apps used it for 5 days.
Sudddenly i started facing network issues. I was not able to make or receive calls. Strangely, I was getting data connection from network but not able to make or receive calls. I could not register on any network.
I tried running GalxSimUnlock app again and it said Unable to read NV data.Since I was naive i tried reinstalling the stock ROM and SIYAH kernel to see if it helps. It didnt.
When i researched further i came to know there's probably something wrong in the NV_data.bin file in EFS . But i hadnt taken backup of EFS previously. Now can anythng be done to restore the EFS and make the phone work? Please help me....
When i run GalaxSimUnlock app it shows everything in green except IMEI number which it blinks in red. But I am able to see a IMEI number and it doesnt look like something default. I am getting everything else MAC id, baseband version etc.
Thanks everybody...please forgive my language if not upto the mark as i am pretty naive about this stuff.
Please Review this thread [GUIDE] Recover your IMEI in 9 steps.
If you have specific question on the process, you can post this thread as well.
If that does not work and you need further help, please post in Galaxy S II Q&A, Help & Troubleshooting
Hey Buddy....Thanks for replying....i just saw you have written you flashed the original ROM on your device again...but as I wrote I have flashed another ROM and didnt take back up of original one and cannot find the SKT korea S2 ROm for this one...Is it ok if i employ the procedure told by you without flashing original ROM...what is CSC? Is there anything else you wanna tell me before i start the process? please forgive for my ignorance Im quite new to all this...
You will have to ask on the thread I linked regarding the Rom. You will have the right experts for your device there.
CSC is sales code., you can check your ROM CSC by dialling *#1234# . First two digits represents country and last three represents release time.
ok thanks...i will post the question there
Per Suggestion from my Collegue @It_ler,
The kernel you have is older. Latest SiyahKernel for the stock JB ROM he has on his device is SiyahKernel S2-v5.0.1.
If you have questions about the kernel, then use the [KERNEL][REF][Q&A] Siyah 5.0+[ICS/CM10] 6.0b5+[JB/CM10.1] +DISCUSSION+. NON-DEV!!! (SiyahKernel discussion) thread.
Hello dear ones, I'm lost and I need your help.
I've bought a used SM-g920f, knox x0. It worked flawlessly. Until the first evening when in the middle of a phone call the phone app crashed. After resetting the phone it was still unable to connect to network. I have noticed that baseband/IMEI were set to unknown and so it could not read my sim card.
First I have tried the obvious - upgrading from lollipop to marshmallow. It went easy but did not help. Neither did help resenting to factory settings.
I have rooted and installed twrp recovery adb and stuff.
After almost two days playing with it, I seem to be out of options.
What I tried:
Flashing Different roms - stock and non-stock. (G920FXXS3DPB2_G920FXEU3DPB1_G920FXXS3DPB3_HOME, G920FXXS3DPB2_G920FOXX3DPB2_G920FXXS3DPB3_HOME, Pure-Stock.ExtraLiteROM_XXU3DPCA.DEODEX-v5.5.by.ambasadi, XtreStoLite-ROM-3.0-Final-DPCA) - I do not know the country of origin of this device. (the back is from testing unit), is there some way to know correct original stock ROM ?
Flashing Different modems - (G920FXXS3DPB1_Modem_TWRP, G920FXXU3DPB6_Modem_TWRP, G920FXXU3ZPA1_Modem_TWRP)
Checked sim card in another phone/different card in this phone - if sim card would be invalid, would I still get missing baseband?
Xposed Imei Changer - it did change IMEI. But that's it. Baseband still missing.
*#0011# and other *# stuff..
And I have wiped /efs (it did generate new nv_data. Guess now even broken IMEI would make ma happy)
Any ideas ?
How can I know what can be wrong? /efs partition? wrong firmware combination? hardware issue?
In Samsung Phone Info I get empty on Modem Board, Hardware Revision,Samsung Serial Number,Baseband Version.
Than you for any help or idea!
tried smart Switch emergency reinitialization?
Just to be sure, knox is triped now?
Im installed a custom rom (CM13 6.0) For My Galaxy J7 (SM-J700F) After that my IMEI had changed and i can't use my netword and calls again .
how i restore my old IMEI again ?!
I think if you flash the stock rom your old imei will be back
If possible Plz Find another J7 which have custom recovery and backup his efs than put it folder from his phone to ur phone In backup folder than restore it...
I think its backur network....
Note: Do it first before Flash any rom... Backup all files with twrp
Same Problem here
Hi I'm using the Galaxy J700H phone its like 2mos old, and have the exact same problem, so please can someone help? My problem is, I think also is my IMEI number? When i dialed *#06# on my phone my IMEI is 350000000006 and FTW that's not even my IMEI anymore, I have the original IMEI number here backed up but i tried everything, step by step. But sadly nothing worked out. I used this sim card in all of my phones and lastly when i wiped out my phone and flashed custom rom in it, then this happened, then i decided to flash the stock rom that has been downloaded from the sammbobile.com website, after that nothing happened. My phone always displays EMERGENCY CALLS ONLY.. pls help
Hello everyone.
Sorry if my questions are silly, I'm quite new here... and I need some explanations.
I bought a phone ( reconditioned, on PriceMinister) that I'm having some trouble with.
The main issue is that IMEI (MEID) written on the back of the phone does not match the one shown when i dial *#06#. Still, the S/N is the same.
Also the model written on the back ( SM-G920F ) does not match the one when I enter Odin mode, ( SM-G920P)
1) Is it safe to name my IMEI N° here or elsewere on the net ?
2) Is it possible that I changed this IMEI myself, being unaware of what I was doing while flashing TWRP, or some ROM that I randomly tried ??
3) What tools can I use in order to know what is really the model of my phone ( TWRP SM-G920F alias zerolfte does not work, but zerofltespr does. Still the Pi3 ROM works when I state the model being SM-920F !)
Thank you for your suggestions.

Hi folks,
I tried to install MicroG-LineageOS14.1 https://download.lineage.microg.org/a5y17lte/ but noticed that SIM card, IMEI are not recognized with this ROM.
So I decided to going back to stock Android8 Oreo, but now, SIM card is recognized, but I don't have any IMEI number if I call *#06# or by looking in phone information.
What can I do to recover the IMEI ? I have a Nandroid backup of LineageOS 14.1, maybe /efs (if it's the good partition) have the good informations ?
(I know my real IMEI number)
Any hint to recover my phone please ?
Regards
OK, figured myself by searching, reading, digging a lot:
restored /efs partition (2MB) from my Nandroid backup of Lineage14.1 had worked
W00t !
hello, i have the same problem and no backup. Any ideas on how i can solve this?
