I am done with my research and yes I came with a big F in my certificate. I am exhausted, disgusted and utterly pissed! With that said, here is what happened, what I did to solve it and what was the aftermath.
What happened?
I got a Samsung Galaxy Note 3 SM-N900 as a gift from my friend. He purchased it from United States. As you can expect, I wasn't aware of this popular issue for Galaxy Note 3 because I didn't plan on purchasing it. If I would, I would have done my research. The phone, as beautiful as it was, arrived in its perfect state and worked like charm with one of the Bangladesh carriers (I used Grameenphone just in case any of you were curious).
Things were working great until I had to go to US myself. I had a transit in Saudi Arabia for about 12 hours. In the meantime, I purchased on of their local SIM card and stuffed inside Galaxy Note 3 (stop biting your nails. I know I screwed up). It worked like charm too. Arrived in US. Purchased a T-Mobile SIM card and surprisingly it worked great with that one too.
Things changed when I came back to Bangladesh though. Now that I am in my home country, the baby doesn't recognize its mother anymore. Not even a single carrier's SIM card gets detected inside NOTE 3. Instead there is a "X" sign on the top of the SIM card icon. To make it worse, the IMEI number is also gone. I know you wouldn't believe but I didn't go through any flashing process whatsoever. The only thing happened is I changed my location geographically. Since then, I never got it working. I never actually tried to get it working as I had so many phones in my stock.
But things changed. With time, my primary and secondary phones disappeared and I am only left with my Galaxy Note 3 (the last one got stolen). As a last resort, I tried everything but failed. According to the popular issues in internet, my phone doesn't ask for any sort of codes whatsoever. I am actually never greeted with that screen. The problem I have is, no matter which SIM I put in, it never detects. Any network related number execution obviously returns with "Not registered under network" (codes like *#06#). Tried the Region unlock away app by Chainfire and also didn't work. Tried tonnes of custom ROMs that didn't solve either. Right now before posting this question, I am downloading the stock 5.0 firmware from SamMobile for Bangladesh carriers. I hope it works but it will be my final try. After that, I live that upon you experts. Can you suggest what to do?
The actual problem
1) No SIM card is detected.
2) IMEI and IMEI SV says Unknown
3) Also a nifty info is after I used the Region Lock Away, it said the process failed because it "couldn't locate CSC data! You could try flashing a CSC package to correct this"
4) Just if you are curious, yes of course my device is rooted and currently running Lineage OS.
Thanks in advance.
2) IMEI and IMEI SV says Unknown

Now would you call it a self destruct if I said I don't have anything backed up? The IMEI disappeared when I arrived in Bangladesh and turned the phone on with the local carrier.
There has to be some way to get the SIM working, right?
Self destruct if you mean fail to read the basics then yes.
Suggest search IMEI problem amongst theo thousands of posts one or two succeeded .

My i9500 has driven my crazy since yesterday, I even stayed up all night trying to find a way to restoring its IMEI. So here's the problem:
I was playing a game called "Friendly Fire" and decided to turn off its notifications using Application Manager. Everything was fine until a few hours later when I opened up my phone and saw the mobile signal was gone, only a circle with the diagonal dash inside it left. At that time I thought it was fine but then suddenly it popped up the message "Please enter SIM card unlock number" or sth like that, which was an error indeed because my i9500 is an unlocked version. I though it was the mobile network who locked the SIM, but when I tried putting the SIM into other phones, they all worked! And so I started to find a way to unlock my i9500 by ServiceMode Menu but I could never reach the ServiceMode Menu, it only showed a blank screen. I checked my IMEI and it now said "null/null". I had never rooted or flashed any ROM on it so it was really really strange. So I reached a topic on "how to solve the null/null IMEI" on i9500 because it seemed that many people got this problem. However, nothing helped I even rooted my phone to see whether I can back up then restore the 'efs' folder. Well, I did manage to do so but the IMEI would not change at all. The strange thing is that when the phone was just booted up, if I enter *#06# the IMEI shows "null/null", but if I enter *#1234# first then *#06# it shows the generic IMEI (0049...), which was useless as well. I tried different methods, flashing to different official stock rom, but nothing worked. Also, when I flashed an official stock rom, Kies did not show the right region of the firmware but "XXX" for every firmware I tried. And of course, my mobile signal was lost so I could not make any call/text/3G/LTE/etc., but the rest (wifi, bluetooth, gaming, etc.) was okay, it is basically an ipod touch right now
I wonder if anyone can help me with my problem? I know my real IMEI number (at the back of the phone) and that's it. I bought it from another country so it would not be possible for me to bring it to the Samsung store where I got it from. I could not remember the country where its first firmware came from Is there any way to find out that?
Many thanks for reading my trouble :crying:
Well this weird, I am wondering if an android virus could do that....

I bought it in the U.S. in July, from an official Samsung store. Well, the box containing the phone and the phone itself were "made in China", I thought most products have those words? It would be ridiculous if that is the problem because it also has a line like "Korean product"...
I wonder if Octopusbox or SPTbox may fix the problem? I don't know those two things very well though.
I had the same problem on a different samsung phone (Note 2) and i was getting imei 0049 or something like that, Basically my imei had changed or gone. The issue i found out to be a baseband issue so what i had done was downloaded a few compatible basebands and flashed them via odin and eventually got my imei back. There is also this link for you to have a look at http://forum.cyanogenmod.com/topic/77400-booting-issues-and-imei-loose/ just in case it helps. Hope you get sorted.
solve problem
According to your description, you can have a try resert your Samsung galaxy s 4 and then restart it to see weather it is OK? If it still not fine, send it to Samsung After-sales service
Hello
I have been looking for solution all over the internet. Googling my problem and couldn't find a fix. So here is my story.
I've bought a original Samsung galaxy S4 from Thailand. It worked fine etc. no problems at all (I used my home country sim). When I came back
from my vacation the phone still worked fine until I removed my battery and took my sim card away and but it back on. The phone says no service and imei is null / null.
I have tried the IMEI null / null with Odin, I have rooted my phone, I have downloaded new modem also tried to open it by going system main menu (*#0011#) but it was plain black no numbers or anything. Also I have confirmed that my Samsung is genuine. I suspect that my phone is SIM-/country locked
So the majority of the post that I read were back from 2013 summer so Samsung has propably fixed or patched some of the fixes.
Thanks in advance
Maybe start reading further down as Ive seen several threads about that problem in the last 2 weeks.....
I have read through this forum for hours and in no way savvy with this stuff; I have learnt a lot so thank you but please help me.
I just don't know how to tell what the problem is with my phone therefore i don't know which of the 100s of solutions here to apply.
its a S4 i337 previously used on AT&T LTE network, I traveled overseas and used other country's sim card for a short time after giving it to service provider to program. i believe phone was rooted and settings changed for this to happen, though i did not do them or know what they did.
I returned to U.S. and reinserted AT&T sim, made one call, but phone seems to trigger anti theft or network suspend right after. I have had it unlocked twice by AT&T but first use thereafter seems to reblock me out of their network and i get message that this device is blocked from network use. When I call they say phone shows stolen and i repeat process above only to get reblocked again.
I don't know if it is APN settings, previous rooting or what that is causing this? I found an app called SuperSU on the phone, i clicked on its settings and clicked "full unroot" which made app icon disappear but can't tell if I am really unrooted or not. I have also done factory reset and lost everything already, I just want phone to work back on AT&T network as before.

please help me… i am not sure if i need to reroot, delete binary counter, flash with files???? i have read some about odin files, don't know what is the latest and which sources are safe…just confused all around.
please someone tell me where to start
please tell me where to start? do i need safestrap?

Take it to a best buy Samsung service counter and have them reflash the firmware or update it to MK2. Wipe everything (including internal and external SD card) Then, call att to unblock it again. If it relocks, then go back to the Samsung service counter, tell them the issue and see if they can restore your efs for you from a backup. If they can, do it and then unblock it.
If after all this it relocks, its not your device. Its att who are at fault. Then all you can do is to yell at them.
EDIT:
Another possibility is that the ppl who unlocked your phone overseas stole your imei number and used it to revive a blocked stolen phone. In that case your imei is in an international stolen imei database and you are probably out of luck.

Interesting. If the IMEI was stolen, what would the phone show? Would they clone the IMEI (so it would show the same IMEI) or would it come up as UNKNOWN or blank or something. Reason I am asking is that I've been try to fix an issue with my father-in-law's phone that completely lost the ability to connect to wifi/data after having his S4 "unlocked" in Vietnam to use a local SIM there. Tried may reflashes with MK2 and custom TW ROM's but none work with wifi anymore (data works ok).
If data and calling works then the imei is fine. Its some other issue..

All is speculation but there is a small posibility that when you gave your phone that person gave you another phone which indeed was stolen. Your best bet is to go to the samsung guys right now or learning how to restock your phone. You tube search videos How To Unroot & Unbrick Samsung Galaxy S4
so its been a few days now with no service. it turns out my phone has somehow been programmed with a different imei that comes up as stolen according to at&t. so the theory of my imei having been stolen is pretty possible. every time i have the phone unblocked from the network, one phone call or message causes it to trigger the stolen phone alert and kick me out the at&t network. i have been to the at&t store with my device and the original packaging that shows my original and correct imei but the one that the phone is registering on screen does not match what is on my actual handset sticker and original packaging. the phone never left my sight the entire trip so i am 100% positive my handset was never switched, if anything it was reprogrammed with the stolen imei and they stole mine which is now working fine out there for some crook
i just can't believe that at&t can't verify my original imei that came with the phone i bought from them and just reprogram my phone and get my service going again. its looking like i will need to find a way to recover my imei myself. although i just got the 4.4.2 update that force placed itself on my zero service phone. hope this post helps to alert others to be careful of this type of thing.
Wow! what country did u visit?
If your s4 had insurance I would report the phone as stolen and give the original Imei to be blacklisted and try to get a new phone.

You can do unroot and factory reset by follow this link
http://forum.xda-developers.com/showthread.php?t=2624397
I did it yesterday and good the news you can update your phone to 4.4.2
I had been looking at this phone for a while on ebay and despite well... ebay... I had temporary lapse of good judgement and maybe a bit of alcohol and pulled the trigger.
I got the phone thinking it was a SM-N910F, everything I'd read said it would work on US AT&T sans some bands for LTE.
The phone came and it was in good condition. The box and the serial label behind the battery all say SM-N910F.
I turned the phone on, it has a beautiful screen, everything seems to work fine, works with wifi no problems, so far so good.
I turned it off, popped in my ATT SIM and turned back on and, uh oh, got an invalid SIM error.
Ok so next step, I go to the ATT store, they check the IMEI and confirm that yes it will work on their network and they give me a new SIM for good measure. Their new SIM still shows invalid in the phone and the sales guy is confused but then I tell him I got the phone off ebay and he gives me a look of pity. No problem though I wanted the international phone so I could learn about flashing ROMs and such without leaving me with a non-working brick and no communications device.
So I read through XDA posts and various tutorials over the web and try to find out why it's not accepting my SIM.
I flash TWRP, and root the phone, that worked fine.
Then I decide that maybe upgrading the firmware to Lollipop and flashing a new ROM might fix the problem. I go to Sammobile, download N910FXXU1BOB4_N910FOXA1BOB4_DBT because that seemed like a good one that would work. Then try flashing it via ODIN.
ODIN Fails, SECURE_CHECK_FAIL : aboot. Some more reading later I find out that usually happens because you're trying to flash the wrong thing.
So I dig further. I can still get into the stock kitkat software on the phone so I download *Samsung* Phone Info and check out what I've currently got on the phone, but now I'm totally confused because I don't know what to make of it and this is where I need some help.
I've got screenshots but due to being new I can't post a link, I can email them if they'll help.
Settings > Device Info shows SM-N910F with baseband of N910FXXU1ANK4... that looks right
but then I fire up Phone Info and it shows a phone model of SM-N910P which would be a Sprint CDMA phone? and a country CSC of CHN?
so this phone is truly international
European phone, Chinese CSC, with USA Sprint firmware?
Where do I even begin, can anyone suggest what I can do to untangle the mess?
Have you check the box "OEM unlocking" in the developer options menu? This allowed me to use Odin the first time on my tmobile note 4.
If you don't have a developer options menu in your settings, go to about device and press build number 7 times until it tells you you are now a developer.
try a European version BTU from sam i have the same model SM-N910F root is an issue i'm looking at.
as the SM-N910F is Euro i would use that firmware.
Hope it helps.
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
