samsung galaxy s4 Unknown IMEI Unknown Baseband Unknown Network - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

i was using this phone for like 3 years
just recently it started doing this where it would show no service and a quick reboot would fix the problem
now as of friday the day after thanksgiving the phone shows null everything no matter how many times i reboot and ive put new simcards in to check if that was the problem and it wasnt the simcard
i doubt the efs files are corrupted because i only flash stock OTA updates through odin no custom ROMS and ive taken very good care of this phone and follow tutorials to the "T" when i do anything of that sort
but anyways ill list everything that is null/unknown so you have a better idea of what the problem might be and in advanced id like to thank you for any help you may give me
i just want to give this phone to my mom to use.. its crazy right when im done paying it off that it stops working its basically an ipod now hopefully you can help me fix that
here we go....
Baseband Version: Unknown
Network: Unknown
Mobile Network Type: Unknown
Service State: Out Of Service
Mobile Network State: Disconnected
My Phone Number: Unknown
IMEI: Unknown
IMEISV: Unknown
Serial number :12580db0
if you need anymore information i will gladly give it to you thanks
and for the record that information is with a working sim card in it
i was on rooted 5.1 or something like that when it started doing it
and i downgraded through odin to stock OTA NB1 4.4.2

URGENT Help! Emergency Calls Only

i'm sorry for the long post, i really appreciate your help
i really need help to get this galaxy s3 GT-I9300 to regonize my sim card.
i bought it from ebay i've used it for a long time works fine,
but because it's an unlocked version and from ebay i'm not sure what region it is
i messed with rooting and stuff and decided to do "restore to stock".
i thought it'd be easy like the nexus or iphone, i followed this guide. it restored the system apps/firmware fine but still keeps all existing data instead of deleting them like it said.
and then when it boots it shows "LaFleur" which i never saw before
and now it's "emergency calls only" does not recognize sim (100% not the physcial sim card problem)
i tried this but did not work.
i also went to settings -> mobile networks-> search results were AT&T (correct carrier i'm using) but it says "your sim card does not allow a connection to this network"
i know i made something wrong with the software not hardware but i can't understand why official tool (Samsung Kies) broke my device.
Please help because i receive a lot of calls so i need to get this working again ASAP. Thanks a lot
I'm sorry i just realized that i posted in the wrong forum, it should be in Q&A
By using kies you've restored what ever firmware the phone was manufactured with, it doesn't sound like an unlocked handset.
Instead follow the guide in general forum, stickies, to flash your own countries generic rom, then factory reset.
Your network issue is likely to be a result of the handset not being properly unlocked. None of the free patches to unlock work with newer firmwares -by updating you've reinstated the network lock. If you made a backup of the efs folder before you started then you might be able to restore and go back to a firmware that can be patched.
Otherwise you've have to buy an unlock code.

I also have the feelings that this phone was not properly unlocked. So the eBay guy sold me not a factory unlocked version but a version he unlocked on his own?
Forgot to mention my IMEI is now 0049... My baseband now has "BELL" in it (Canada carrier?) Also it does show the phone number in About-Status. But network state is out of service.
I don't understand how an official program changed my IMEI to a generic one and I have no EFS backup.
Mod Edit
Please refer to the stickies in General before posting.

[q] sprint galaxy s4 : Unknown - baseband/imei/software version

My phone was previously unlocked... I installed a custom rom and after that my phone started acting up... It wont read the sim card and when i went to check the settings it tell me that the baseband is unknown the imei is unknown ans the software version is also unknown.... If anyone has had this issue and has been able to fix this can someone please help me
I happened to me once, and I flashed a Stock original ROM via ODIN and it fixed it, although I had to call Sprint because whenever I tried to make a call it gave me an error message, apparently I got "kicked off the network". Next time do a back up of your efs folder!!!!!!!

I tried that more than 5 times but my efs foldel does not have the nv_data.bin it seems to be missing... and i cant call sprint because i am not on their network

''not registered on network'' error please help!!!

ok straight of the bat im a total noob with odin alll android firmwares and phones etc.
much to your displeasure i am an apple fanboy... but i really need your help guys!
my situation is as follows: i bought a samsung galaxy s4 relatively cheap of an aquaintance, i used a link on a forum here to see if it was blacklisted and results say it wasnt, i bought an unlock code and it worked ''network unlock sucessful'' YAY... then i try and call the number and after a while im redirected to 02 messaging service. next i try to dial out and i get hit with the not registered on network error. now funny enough i get a warning triangle saying no service yet i get service bars and even 3g; also when i select a network manually and choose 02 it says registered.it also says emergency calls only.
basically i need your guys advice and solutions...
why it may be this way: well as soon as i got i rooted it and it worked i believe this was on 4.3, pretty much as soon as i had done this it was throwing this error at me, after a long time i came back to it and researched more into this golden restore, and the phone was locked to ee now there modem doesnt allow access to the service menu so i changed my modem, when flashing on odin i have tried pda and phone,,,(idek what im doing) i have a GT-I9505 on rooted 4.3 (not sure which root) with baseband: I9505XXUEMK8 and a build number:JSS15J.I9505XXUEMJ8
basically im asking one of you guys how do i reset this to stock 4.3 by flashing with odin, its originally locked to ee but now its been unlocked so can i use btu not ee files? have any of you had this problem and how did you overcome it?

Unknown Imei number

Hey everyone, I know this is an age old question but all the other threads I've seen like this don't seem to fit my exact situation!
Long story short I bought a S4 with Koodo from a secondhand store. I know it's with Koodo cause the Koodo service app is on it. It also had super su on it so it was rooted before.
basically it says Imei unknown and when I try to put my Sim card in it says "emergency call only".
All the other threads I saw mentioned that their baseband version was unknown as well and the Imei sv number was unknown as well, both of the numbers however are viable in the about device tab in my phone. It does say Bluetooth address unavailable though
I am running andriod 5.0.1!
so what can I do (if anything)
Thank you for all your help! If you need any more info please let me know

@irfanbd94: You should have posted your comments to your thread instead of this one.
Take your phone in for service. Trying to transfer the IMEI of a defunct phone to your working phone is illegal, period. No discussion of how to do it is allowed.
