Lost IMEI Number? - Nexus 4 Q&A, Help & Troubleshooting

Hey guys. I would love some help here; recently I had my Nexus 4 lost, and found again. I called Virgin (My phone company) and cut my phone service off. Once I found it, I called and turned it back on. For about an hour it kept saying that the network could not be found, and when I tried to force it to connect in the settings, it said my sim card couldn't be used on the network. I did factory reset from the menu, but it only got worse. It than wouldn't even recognize I had a sim card. I looked online about IMEI and typed in #*06#* or whatever it was, and there was nothing there. Completely blank. I have no idea what to do, and am currently trying to flash stock rom. If it helps, I was running Paranoid Android 3.99 RC2 when I turned my phone service off. Any replies would be appreciated. Thanks.
*EDIT*: I restored to Android 4.4 using the factory image provided by Google, and I now have a IMEI number, but it still wont allow me to connect to the network.
*EDIT 2*: After doing some research on the Virgin site, I found out that there was a blacklist that your phones IMEI goes on after reporting it stolen. Basically, when I called in to get it off of it, it was never taken off. Those ****ers said it was going to cost me $150. This thread can be kept for future reference to other people, or deleted if needed. Thanks.

Below are the threads with same issue.. Have a look over them and see if it helps.
In all the cases, the users were on PA RC2.(This ROM might be causing some problems)

Thanks for the info, but I now have a IMEI number when I flashed Google's stock 4.4 image, but it still says it cant connect to the network. Any ideas?

Just restore any CWM or TWRP backup. It worked for me after i lost my imei and basband while flashing 4.4.

Nothing to do about a blacklist. Ask them again and explain the situation. Contact a consumer rights organization otherwise.

"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

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...

Not Registered on Network

Hi guys,
I recently picked up a used S4 on Craigslist for cheap because the guy "screwed up" using Odin and flashed something that caused his phone to not register on any networks. I figured, what the hell, it's cheap enough and I might be able to restore it. So far I've restored the Rogers firmware over Odin and tried installing a custom rom/recovery too. I'm still getting this problem unfortunately. The IMEI reported with *#06# and in the status screen does match the sticker on the inside of the phone.
So I'm sure everyone's going to suggest that the phone was stolen and the IMEI has been blacklisted. My provider (Fido/Rogers) apparently doesn't care if the IMEI is blacklisted, they'll let it run anyway. I called up Fido anyway (since I'm a Fido customer) and asked them about the IMEI of this phone and they say they don't have any record of anyone calling in reporting it stolen and they don't have an IMEI database so she didn't have much to say about it.
Does anyone have any other suggestions? I've also flashed just the kernel, and I will flash a modem onto it too. I know my SIM card works, and both my SIM card and the last owners SIM cards don't work. I know the radio works because it picks up the emergency signal fine, and the SIM tray isn't damaged because when I put in my Fido SIM the Fido APN's automatically come up, as well as the lock screen goes from "No SIM inserted" to "unregistered SIM." Could my EFS partition be borked? Wifi works and IMEI shows up correctly.
The buyer said he would take the phone back if I can't fix it, but I want to try a bit more before I give up. If anyone has any ideas or suggestions, that would be great. Thanks a lot in advance XDA!
Summary:
-Used S4
-Owner flashed something wrong in Odin
-Gets "Not registered to network" error, unregistered SIM error
-Tried restoring
-Tried new ROM/Recovery
-Carrier says IMEI is fine, also tried directly registering the IMEI to my account
-IMEI is correct in settings/sticker on back of phone
-Wifi/everything else all works
Sounds like it's SIM locked to a different network. Try the the guide here: http://forum.xda-developers.com/showthread.php?t=2285431

My girlfriend has a Bell sim, which when we insert, gives us the "Please enter unlock code" screen.
My sim does not do that. I know this device is for my carrier, but I figure the easiest way to get this going is to just unlock it and see if the problem persists on other networks.
I've tried that unlock tutorial before. The first time I tried it, when I just got the phone from the previous owner, it said "Golden-backup does not exist" so I couldn't do the restore step of that guide. After Odin-flashing everything and starting over, I can't even get into the UMTS menu anymore! I'll try another restore and give it another go though.
Edit: Another problem. I did a restore again using Odin and notices that it never properly wipes the phone. When I finish flashing, my Wifi still autoconnects on first boot, and every few seconds, a process crashes causing the phone to freeze. Has anyone heard of this kind of problem before?
Quick update:
Managed to Odin-flash it to the earliest firmware I could find for the phone without any crashing or freezing problems. Trying to do the network unlock method mentioned online. It does not work, even though I'm following the instructions to a T. Could it be that my EFS partition is borked and that the NV rebuild can't happen, meaning my radio configuration would also be borked?
Edit: Oh and when I booted up my phone for the first time, the phone was actually ON Fido! But within a few seconds, it went back to "Emergency calls only."
Hmm, that is some odd behavior, and definitely not a carrier lock. Shame it's never that simple to fix.
Not quite the same as your issue, but I lost my ability to make and receive calls after flashing a newer modem on an AOSP firmware. Flashing custom kernels, older modems, the latest stock rom and kernel were no help at all. I tried everything I could think of short of groveling. In the end the only way I got everything working again was to flash the original factory firmware my phone shipped with, factory wipe it from stock recovery, then flash it again. If you've already tried that (and I'm guessing you have), consider contacting Samsung regarding warranty. They've been really good to me in the past, even with second-hand phones.
I can confirm that Odin doesn't clean everything out. In my trials I also noticed that flashing via ODIN without a factory reset presented no setup wizard, caused lots of FC's and left some previous files hanging around.
Sounds like a bad sim tray.

I had trouble with my handset after it got run over in the street, making it's otterbox earn it's money. The only bad symptom after that episode was Emergency calls only kept recurring.
I cut a tiny square of transparent scotch tape, avoided touching the sticky side, and placed it squarely on the SIM chip's backside, to make it fit the sim slot more snugly. It sounds like you should try stacking two or three layers on your chip as it sounds to be more loose than mine is.
Hi everybody! Thanks for all the help trying to fix it! It ended up being that the guys the previous owner had unlock it used the debug-menu unlock method and my phone was one of the ones that doesn't accept it. Lots of other people complained about similar problems as me in the free unlock method thread. In the end, I paid for the FastGSM USB Unlock method and it fixed the problem.
OH MY GOSH YOU JUST SAVED ME from buying another phone!! THANKS so much.. I added 3 layers of tape on the back of my sim and it works!!! weird.. cause I have the Dual Sim.. and it was the first sim that would not work. the second sim was fine.. anyways.. THANKS SO MUCH!!

[Q] Blocked from AT&T after international travel

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 someone tell me where to start

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.

so not able to use phone.
kindly help me
Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.
OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?
I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.
do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.

No Network

Hi good people, I am facing a problem. Around 8 hours back I tried calling someone but the call didn't connect so I restarted the phone and then I lost the network. I tried reboot, flashed different ROMs (unofficial CM14, cm13 nightly build n MM nougat backup), tried with GAPPS and without GAPPS but the problem is persisting. I even tried swapping the Sim cards before that but of no use. I tried debugging by using *#*#4636#*#* but ping test is failed and also there is "TURN RADIO ON" I believe ideally it should be "TURN RADIO OFF". please have a look at the screenshots. I'm almost dying without making important calls.
Update: Guys I have got it working.. Kindly look into my below posts. Please don't misguide people for small issues.
Thanks
In the screenshot we can also see, GSM SERVICE IS OFF. it stays the same even after clean flashing a new custom ROM.
Got it working. Flashed latest COS ROM file however the situation was still the same. Then I removed sim, switched on airplane mode restarted. After reboot inserted Sim then again restarted n then I got the signal
1. Removed Sim card, switched on airplane mode from both power menu and notification toggle.
2. Restart, inserted Sim card and switched off airplane setting from setting. (Notification toggle and power menu didn't work) then got the network.
Please note I tried with only one sim in sim 1 tray. Later I got the network for 2nd sim as well

Which rom did you flash and what was your method of flashing?
You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?
I've had the same problem for almost a month now... and i gave my phone to the service center. They called up to inform me that its a motherboard failure and they'll fix it.. I'll provide further info when I get my phone back (probably in 3-4 days)
P.S I tried almost every method to make it work. So if you couldn't make it work in first 2 days or so, dont waste your time and just give it for the servicing (make sure its in Stock OS so that they dont ask any questions about root xD )

I flashed almost every latest ROM. But no ROM got the network back. So as a last resort I flashed COS 12.1 and still didn't get the network. Then I removed both the sims, activated flight mode restarted the device, left it couple of minutes and inserted only one sim in first slot. Holla I got the network. Then everything is back to normal
If u r facing the same problem I would suggest u to activate flight mode n restart. If it doesn't work try by removing sim cards, if it still doesn't work try COS 12.1.

You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?

Usual procedure of flashing. Wipe cache, dalvik, system and data. Flash ROM + Gapps. Reboot
Try to search in the forum. There is a lot of threads with the same problem with the Zuk Z1. It is a hardware problem.

Your modem and baseband sections may be damaged. Modem structure is hidden under qualcomm structure. To Access and repair those sections, you need to do some modifications. I managed to make my Zuk Z1 worked again with some tweaking. Altering that part of the phone is illegal due to its restricted elements such as IMEI number. That's why I cannot post a tutorial here. İt is not allowed. However, I can help you if you personally contact me. I hope you get your signal back soon.

Please follow xda rules and don't tell people illegal things where they get in trouble. Keep in mind, that's not an illegal forum
Sure thing but I have already mentioned it. I didn't post anything illegal. So, take it easy.
