[Q] Samsung Galaxy S4 i9500 suddenly lost signal, imei, baseband, etc. - Galaxy S 4 Q&A, Help & Troubleshooting

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

"Original thread"
Hello everyone,
Well, back again with the problem that can't find any solution anywhere.
I've opened a thread about fake imei on this site earlier which can find a solution already. Now the imei and the S/N become original one but the phone still can't make any call. I found the thread about a patch that can fix this issue but it works with NOTE2 and S3 only... so, I'm afraid to try that with my S4 GT-I9500 since it's very hard to find a fix for its problem... I don't want another problem for my phone now...
So, the status of the phone is unlock, root, on latest stock firmware(I9500XXUBMG1), Baseband is I9500DXUBMF8,
Software status on phone: Network=Unknown, Mobile Network Type=Edge:2, Service State=Out of service...
When I check with AndroidDump the Telephony said:
IMEI=(my original IMEI)
CallState=IDLE
DataActivity=NONE
DataState=DISCONNECTED
NetworkType=EDGE
PhoneType=GSM
SimState=READY
CellLocation=[16427,50572,-1]
DeviceSoftwareVersion=01
Line1Number= (it's blank)
NetworkCountryIso=th
NetworkOperator=52018
NetworkOperatorName= (it's blank...again)
SimCountryIso=th
SimOperator=52018
SimSerialNumber= (my sim serial number)
SubscriberId=52018961057xxxx (this is my IMSI)
VoiceMailAlphaTag=VOICEMAIL
VoiceMailNumber=1802 (this is the voice mail number of my sim operator)
Now, let's go back a bit for earlier problem of my phone...
It's been stuck on Samsung logo(bootloop) because of EFS folder corrupted(Error mount efs)
Solution: I forced the efs to mount by enter the command in Terminal Emulator on Recovery mode, then the phone reboot normally with wifi connect but fake Imei(004999xxxxxxx) and S/N 00000000000. So, I can't make any call since then but can connect wifi.
After that with the fake Imei and S/N all zero I've finally found a mobile repair shop that can write the original Imei and S/N for me with the SPT Box. So, my phone has the original Imei and S/N now but when I try to make call it said "Not registered on network"
If I choose the network manually(My operator is DTAC) it will be Network(DTAC)unavailable... If set to choose automatically, it looks fine but when I attempt to call it said "Not registered on network" again...
The phone still can connect to WiFi, as usual... but can't make call...like before fix the Imei and S/N
Contacted the operator of my sim already and they said it seems to be the problem of the phone so, I have to contact Samsung... but my phone has no service with Samsung coz it's the phone from another country and it's been root already...
I've tried every way I can(found on this site and other site...) None work...
So... anyone has any idea why my phone can't make any call???... and HOW EXACTLY TO FIX IT???
Thank you again for you time and help...

This is why you should always back up your EFS folder. If your IMEI ever gets lost you can restore using the EFS backup folder very easily.

You were ABSOLUTELY right. I had done NOTHING wrong, my IMEI had been blacklisted by a weird mistake of a mobile company.
I'll explain my jourey, in the hopes that it can help somebody, since, I HAVE A SOLUTION for every single case of this issue.
1) When I got my gt-i9500, of course I rooted it, then i proceeed to flash PAC-ROM on it, but I had to go back to Stock (Arrow Modified Version) since PAC-ROM is FULL of glitches ans bugs.
2) After a week of being using ARROW, i got the "NOT REGISTERED ON NETWORK" problem. Not instantly, no, AFTER A WEEK OF USING AS MY DEFAULT ROM. I got really scared, since I DIDN'T MAKE A BACKUP OF MY EFS FOLDER, and when I review my IMEI, it wasn't even the 00049... generic one, it was null/null. So i shat my pants, thinking I had ruined my S4 for good. But I started reading. First i had to get my IMEI back to its original form, and then work around the network issue (THAT'S THE ORDER, ACTUALLY)
3) So I downloaded a whole bunch of modems and tried one after one, with no success, some of them put the generic IMEI on my phone, some of them got my IMEI back to null/null. I was worried and drinking industrial quantities of wine at this point. So i went for the obvious but way more boring solution. I TRIED FLASHING STOCK ROMS on my S4. I live in Perú, so I only have 2 choices to do this, and actually my carrier stock rom is not even listed on SamMobile.com (I'm on Nextel Peruvian 3G network). The 2 choices i tried, neither got my signal or my IMEI BACK. I started going desperate, but keept on reading.
4) Tried the MTK Droid Tools to recover my IMEI. I had never even used The ADB android interface before, but learned rather quickly. Got my S4 connected, shell rooted, and still couldn't change my IMEI; since MTK Droid Tools (and please trust me on this one) ONLY WORKS FOR THE CHINESSE/KOREAN VERSIONS OF THE S4. So don't even bother, you might learn ALOT about the android ADB interface, but won't fix your IMEI.
5) Finally I started downloading a bunch of Stock roms in order to get my IMEI fixed automaticaly by flashing them through ODIN. And the I stumble upon THIS ROM: http://www.sammobile.com/firmwares/3/?download=17396 WHICH SEEMED like a divine answer from heaven since, just by flashing it, got me back my ORIGINAL IMEI.
6) At this point i had discovered that INDEED the MODEM: I9500UBUBMG9 does get your IMEI back to its original state. (That's your answer). SO, I was in a Stock rom, with my original IMEI, bu had NO FREAKING SIGNAL WHAT SO EVER. STILL HAD THE "Not registered on network" FREAKING problem. So I, finally, gave up, came here, and got the answer that It might had to do with my IMEI being blacklisted. I refused to believe so, since there are this stories on the internet, that you can actually screw your EFS folder by installing a custom AOKP rom without backing it up, and that there's this "RF CAL" file that only samsung knows how to fix and once it's corrupted, you won't be able to connect to any network, ever. BUT HERE'S THE THING, THAT story IS A LIE.
7) I went to NEXTEL (My carrrier) support (They sold me the phone) today, and YES, OMG YES, my IMEI had been blacklisted, AND HERE'S THE CATCH: ANYONE (At least that can happen in my country) ANYONE, can call your mobile operator, reporting your phone has been stolen, and the op will block NOT ONLY YOUR NUMBER, but your freakining IMEI, blacklisting it, and making it IMPOSIBLE for you to get connected on ANY network.
SO Here is my conclussion to this WEIRD case:
1) If you have the NOT REGISTERED ON NETWORK and you have the WRONG IMEI issue (Meaning, your IMEI is the generic: 00049... or Null/Null) , flash via ODIN, THIS STOCK ROM: http://www.sammobile.com/firmwares/3/?download=17396, just... flash it, I DON'T CARE IF YOU'VE READ THAT YOU JUST NEED THE MODEM, I garantee that if you flash this stock rom, your IMEI will go back to its original state.
2) If your S4 is on an Stock Rom, and you have your original IMEI; and you still can't connect to your network, It means your original imei has been blacklisted, and you NEED to talk to sammy or your carrier to fix this, or contact someone who can undo this situation.
That's it. I hope that my journey helps someone that is trying to get this "NOT REGISTERED ON NETWORK" issue solved, as I've been trying to for the entire weekend. Just... don't give up. http://forum.xda-developers.com/images/smilies/good.gif

BUT HERE'S THE THING, THAT story IS A LIE.
7) I went to NEXTEL (My carrrier) support (They sold me the phone) today, and YES, OMG YES, my IMEI had been blacklisted, AND HERE'S THE CATCH: ANYONE (At least that can happen in my country) ANYONE, can call your mobile operator, reporting your phone has been stolen, and the op will block NOT ONLY YOUR NUMBER, but your freakining IMEI, blacklisting it, and making it IMPOSIBLE for you to get connected on ANY network.
SO Here is my conclussion to this WEIRD case:
1) If you have the NOT REGISTERED ON NETWORK and you have the WRONG IMEI issue (Meaning, your IMEI is the generic: 00049... or Null/Null) , flash via ODIN, THIS STOCK ROM: http://www.sammobile.com/firmwares/3/?download=17396, just... flash it, I DON'T CARE IF YOU'VE READ THAT YOU JUST NEED THE MODEM, I garantee that if you flash this stock rom, your IMEI will go back to its original state.
2) If your S4 is on an Stock Rom, and you have your original IMEI; and you still can't connect to your network, It means your original imei has been blacklisted, and you NEED to talk to sammy or your carrier to fix this, or contact someone who can undo this situation.
That's it. I hope that my journey helps someone that is trying to get this "NOT REGISTERED ON NETWORK" issue solved, as I've been trying to for the entire weekend. Just... don't give up. http://forum.xda-developers.com/images/smilies/good.gif

it's so amazing that the mobile company staff have so much power, isn't it? I thought the report process should be a bit more formal, with a note from the policeman or something. Otherwise it's so easy to get fxxked up for doing nothing...

[Q] Samsung galaxy s4 no IMEI and more

Yesterdag I received a Samsung Galaxy S4 I9500 from a friend.
He said the phone came from India, but he was sure he was unlocked.
After putting in the SIM card, the phone did nothing, it didn't recognize the SIM and didn't even ask for a PIN Code.
So I thought that he was locked, I wanted to use *#0011# to go in ServiceMode and unlock the phone. But after going into the ServiceMode, it didn't show any options at all. It was just a screen with ServiceMode on top.
I know there are other codes to come in ServiceMode but even these wouldn't work.
After that, I did *#06#, and a little popup came on the screen with "IMEI null/null"
I found the fix on the internet for this, but even this was without succes.
I tried several other roms and modems, but that didn't give me any progress.
Does anyone has an idea how to fix this? I really don't know what to do anymore.
The phone is brand new. Nothing has happened with it.
Thanks in advance!
Flash one STOCK ROM in Download Mode using Odin 3.09
*EDIT: If after these steps the imei still null/null then the problem is hardware. U will have to let ur phone in SAT (Technical Service Assistant)
I find that almost impossible to believe. In my experience with the Galaxy series of phones over the past couple of yrs, IMEI's do not disappear for no reason all by themselves without anything being done to the phone. 'Your friend' has left out a bunch of information here.

Hello, thanks for the fast reply.
I don't think so, he unboxed it, tried a sim card. After he saw the sim wasn't read at all.
He gave the phone to me ..
He came straight out of the box without a IMEI number in the phone.

IMEI number messed up

Hi,
Let see if someone can help me.
Im trying to help out a friends cousin, he came here to sweden from the war and hes mobile dosent work, so he cant call back home to contact anyone there.
This is what i need help with.
He have a Samsung Galaxy Note 4 SM-N910C and he bought it in turky, to be avaible to use it in hes contry they had to root it in turky (this is what he said) and they rooted it for him.
But the dident seem to leave a backup of the orgininal efs map or anything, have checked the phone storage and even the SDCARD he bought at the same time that he have never formate.
So since the IMEI number is wrong he cant connect to any network here in sweden, the IMEI number goes to some Philips phone.
So i tryed to restore the IMEI to the one on the back of the Note 4 phone, i though i was succsessfull since *#06# shows the right IMEI number now, that match the one on the back.
But when i go into Settings->About Device->Status the IMEI number is still the Philips one, i tryed to recreate and remove the efs folder but ended up with NULL or 000000000 IMEI at Device status.
Can someone help me? me rly wanna be avaible to call home and do video calls with rest of hes family still at home in the war.
I even tryed upgrade firmware and downgrade i have tryed a custom firmware and official.
Tryed changing mode firmware and everthing, been trying to get it to work for 4 days now.
And he dont have any money to buy a box to fix the phone.
Thanks,
As far as I'm aware, transferring IMEI numbers etc is Illegal. This reeks of something illegal.

Greetings,
Changing the IMEI is illegal in most countries and therefore discussing it on XDA is forbidden. I hope you understand.

Samsung Galaxy Note 3 SM-N900 Region lock issue

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
RESTORE your backed up EFS folder .

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 .

Samsung S7 SM-G930F wrong IMEI and model number

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...
