I'm getting ready to return my recently purchased skyrocket due to the "no sim card" error (it never worked since purchase last week). I had already installed a few custom ROMs and radios trying to get it to work, so I went thru the process of attempting to return it to stock. In download mode I don't see any indication of the flash counter having incremented. However, when I type *#06#, the IMEI number shows the expected number followed by a /6. On a different stock ROM it showed /7. It seems to be changing as I flash different ROMs. Does anyone know what this number indicates?

OK it looks like this is the IMEI SV (Software Version) number. Does anyone know if this affects the Samsung Warranty? Should it be some specific value, and if so, how to force the expected value?

Hi everyone,
I have read up a lot on different people in similar situations to myself, but none of the solutions I have found have been successful. Anyway, here goes:
01) I rooted my GT-N7100 (Samsung Galaxy Note II) using Odin and then installed Cyanogenmod onto it.
02) I decided that I did not like CM, so I downloaded the stock rom for the handset and went through the process of putting the phone back to normal
03) This was successful, however, during the process my IMEI number has changed on the OS level, so that now the IMEI written on the device is different to the one that is displayed in the device status.
I am not trying to change my IMEI number to anything other than the number that it is supposed to be, I just want to be able to make calls and use my mobile data again. If anyone has any ideas about how I can go about editing the current IMEI number, I would be really appreciate it. I'm aware that this is a taboo subject due to the legality of changing the number, but all I want to do is get my phone back to the way it was.
Please feel free to ask me for any further information.
Thanks in advance.
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?
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 Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.
Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !
First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?
Bump.
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!
