"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...

I have checked the IMEI was clear.

i dont know if this helps but i had the same problem ....the exact same problem you are having ,only its that i was having it on the note 2 , also i didnt have the warranty cause of the same reason as yours,so eventually i fixed it after 4 month ,
i first installed the miui rom, then flashed the dmg1 modem on my phone and used the ariza patc, i think it has to be done in the same order cause i had done all three of those before but to no result.maybe you can try this...

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

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 i9500 suddenly lost signal, imei, baseband, etc.

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.

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

Samsung Galaxy s5 (sm-g900t) no signal, not service.

My samsung galaxy s5 g900t started having problem this morning. I;ve been using blisspop rom since 3 month ago and everything was fine. But now my phone wont even find a signal. The signal bar is empty. I though it might have been because of an app. therefore i deleted any unusual app, and nothing happened. Then i proceeded to factory reset and nothing happened, then i decided to change the rom, and nothing happened ( i changed to 6 different roms, all between LP and MM. I proceeded to flash the stock firmware via odin, it successfully flashed the stock firmware, However nothing happened. It has an empty signal bar with and x on the inside. So far I've tried with different sim cards and it happens the same. NOTHING. My phone has been using heavy duty covers since day 1. The last cover i bought was the Love Mei one. Which is Extremely heavy duty. (combination between aluminum and rubber).However im starting to think that i will have to buy a new part of the phone. I know about phones, and software related, however i dont know as much as a professional or amateur would about hardware (external)
Can someone please give me suggestions about what to do before proceeding to buy a new part? If i have to buy a new part, which one do i have to buy? the antenna? or what? I've posted the picture of the screenshot ( look at the signal bar) Forgive me if someone has posted the same issue, however the suggestions xda was telling me are far from being the same than my problem.

Do you still have an IMEI if you type *#06# ?
If not, I hope you backed up your EFS partition before flashing ROMs

No. I didnt. Okay i though it was a lost cause. Here is what happened, somehow my EFS folder got erased, and my imei and S/N were gone along with it. After you lost those 2 essential things every company turns their back on you. So, it is either you fix it by buying one of those boxes that fix imeis and networks related, or buy a new logical board on ebay; or just give up and proceed to buy a new phone. However, even though i saw that my imei was null, and my S/N was also gone, Having no backups of EFS, I was at the edge of giving up. Until i decided to do the following: I installed the firmware that came with the phone. which it was a 4.4.2 version. Then i upgraded it to 5.0. And..... Everything was back... however my IMEI is not the same that came with the phone. Which is kind of odd. How did i get a new IMEI by just goning back and for between upgrades? Who knows.... Anyway, now I have full bar as its supposed to be. And currently 4g. (There was another thing i did but i will refrain from telling, since it isnt that interesting)

Very strange, but good news it's working
I'd would strongly advise you to back up that EFS partition asap now just in case

Ueah. I never thought that would happen to me. Thats why i never did the backup. I did it as soon as i saw that i got signal, service, imei and sn back. Haha

No-one ever thinks it will happen to them, that's why I backed mine up before I even decided to flash anything custom at all

Samsung Galaxy S4 I9500 - NO SIGNAL (IMEI/IMEISV:null/null;Baseband Version:Unknown)

Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer...
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.

My imei & baseband went missing after installing a rom. Now i have no mobile network

Hello everyone Happy Holidays i know all us get some kind of technical issue now and then and as far as im concern this isnt the first time someone else has a problem identical to mine which is having a missing imei and baseband resulting in my Samsung Galaxy Note 4 T Mobile popping up a message saying "no mobile network" everytime i try to make a call due to me flashing a new rom. So i dont think there will be a problem if anybody who knows enough about this subject answers how they were able to solve this problem they had.

Usually a result of corrupted efs folder. You just need to restore this folder from a previous backup and you should be good to go.
You should always, always, always, ALWAYS backup your efs folder no matter what device you have. It's a very improbable thing to happen to get this error, but when it does happen it's a pain to get it back and running without a backup of the efs data.
If you do not have this backed up, the only suggestion would be to take it to a repair center if available.

I really appreciate you being a good fellow and trying to help me out but i already solved the problem my installing a new rom. I did restore my Efs back up with Twrp by the way but that didnt help the only thing left was to use octoplus but i found another way around it ?

Just be careful, I used to own a Galaxy Note 1 and it would temporarly fix my problem just flashing stock, but after a few days it went bad again. I never was able to fix it so I gave it to my little sister as a tablet lol
