I bought vs980 on Ebay, it is not working GPS - no satellite.
On the stock firmware 4.4.2 *#06# is not emei, on firmware Cloudy G3 - there.
In my opinion the damaged section EFS or no correct data in nvram.
Maybe someone will share a full backup to check.
P/S. Sorry for my English.

Well here is my very first post. After much research and study on this site, I have finally confused myself or my phone or both.
So I recently got my hands on my first Galaxy s GT-i9000, bought from a Ukraine guy here in NZ.
Everything works normally except i have no service anywhere i try. Thats how i got it cheap.
It came with VNZ 2.3.3 GB update and with the unknown IMEI problem.
After many attempts, I had managed to get the IMEI and baseband back.
I have since discovered that the original nv.data.bin file was setup for Israel network, Cellcom.
I have tried to flash it with Vodafone firmware again and all seems fine except for No Service. It says its on GPRS mode and the signal is -111dBm 1asu with no change at all.
I have then tried flashing to Cellcom rom that i finally found but it ends up with unknown IMEI AND baseband and I can't seem to get it loaded onto this firmware. But does it really matter what firmware/modem it uses, especially since the phone is in New Zealand.
I've checked and it says it is all unlocked, so it seems that way. But neither Samsung NZ or Vodafone can tell me the real lock status since the phone wasn't originally setup for NZ.
What to do? Anyone from NZ with an imported phone having this issue?
So anyone with this experience got some ideas?
I'm not 100% sure if this is relevant to your situation, but do you have a backup of your EFS?

I've made several backups. They seem to vary though because of the different roms I've flashed with odin.
Sometimes it changes product I'd depending on what regional firmware I try. For example at the moment its running on VNZ but the product I'd is showing up as I9000HKXCEL when it should be set for vodafone. I'm working out how I could change the EFS so that the default code is NZ.
Would it work by editing somehow the product code inside the nv_data.bak file? Would that ruin the IMEI? I have backups over backups if I were to test.
Hey,
NZer (quite an inexperienced one when it comes to Android but I'll try my best) here as well
Uhm. Check the back of the phone, behind the battery. I believe the IMEI of the phone should be written there. Look through your backups and see if any match.
Also, firmware doesn't matter. Think this phone was bought here, but I'm running a UK firmware on it (and previously a Korean one) and its fine.
That's about as much as I can help :/

Hey there thanks kiwi.
Its a weird one I have. I'm currently stuck on vodafone firmware because now when ever I change rom the imei goes away and backups seem to be gettin less reliable lol.
hmm I'm now wondering about what the correct permission and owner settings should be for the efs folder and files. Been using root explorer for most of my alterations.

Thanks for your advice pidio.
I must be doing something wrong.I've I've flashed from sams site and have tried both the latest VNZ 2.3.3 and the latest cellcom israel 2.3.3.
Only one that's working so far is Vnz but when I check with SGSToolbox, the product code is showing cellcom in both the nv_data.bak and data.bin.
It seems my imei or efs setup is "stuck" and won't give me a break through with essentially the "no service" issue.
Hardware wise, despite the bluetooth and WiFi working fine, although chewing the battery life badly and heating up quickly, can the GSM CDWMA part die out separately?
hmmm
Boy I'm so glad I never had this much trouble with the good ol' budget Huawei X5.
Hi!
Resume:
My note has some weird problem with the modems. I'm getting "Unknown" baseband, modem verison, phone number, IMEI etc. with all the modems I tried except one, which shows the correct IMEI and modem version but still not working(I can even see the mobile networks with that one, but I it doesn't connect and gives me "Refresing SIM data" messages).

I always have been using custom roms(only TW) and updating my note to the latest version and I never had a problem.
One day, some months after the last rom update, started to lose the phone network conection and I was getting pop-ups with "Refreshing SIM data"(was very annoying because that was turning on the phone screen every few minutes). Sometimes I had phone network and sometimes I hadn't. The disconnections became more frequently. The phone also started to eat up the free space for apps, so I had to remove several apps to install or update even a small one.
So I decided to change to a different ROM to see if that fixes both problems, but I got the actual problem.
I was in AllianceRom v3 JB when that happened.
I flashed this AryaMod 5.5 JB following their instructions and I got this weird problem. In the "About phone" says that the Baseband version, IMEI, IMEI SV, Network and My phone number are "Unknown". I can't even search for mobile networks because it says "Insert SIM card" when I try to open the Mobile networks menu. Tehre are no signal bars, only a "denied" icon on the status bar.
I tested all JB modems and some from ICS from the "all modems" thread, but I was getting the same "Unknown" things in each one, except the XXLSO, where the Baseband version, IMEI and IMEI SV were okey. I could also find mobile networks with this modem, and the "Refreshing SIM data" thing returned, but it was not possible to connect to a network. With this one, there aresignal bars, but they are empty.
I flashed the AllianceRom and even the old ICS rom I had before, but the problem persisted, even with the modems they came with.
Now I'm on the latest Samsung rom(LT4), unmodified and flashed with odin and the problem persist.
I found this old thread. His initial problem is very similar to mine, but they don't know what caused it nor how to fix it.
I have also found something about corruped IMEIs that you can fix doing something with the ADB and restoring EFS folder, but I think that is not my case because I can see my original IMEI with the XXLSO modem (and I my EFS folder looks OK, anyway I have no backup of that).
I don't expect to get a step-by-step tutorial about how to fix this, but I hope somebody can put me in the right direction. I will post the solution if I find one!
What are the first 4 digits of your imei

Thanks for reading, the four first digits are 3595.
Maybe this is a stupid question, but have you tried re-seating your Sim card, or even a different Sim?
Sent from my Nexus 5 using Tapatalk
I tried both. Also I have been using the SIM with another phone for weeks and works fine. Tried to take out the battery and wait few minutes and other "stupid" things like re-flash a ROM, re-wipe all, etc..
Maybe it's the programed obsolescence, you can use the Note as PDA but if you want a phone, go and buy another...
@ThaiDai or @nokiamodeln91 I believe knows of a way to fix this if its an EFS issue...but you don't have a developer imei
Did you have an old efs backup from when u first rooted your phone?

If it was a corrupted IMEI issue then it should not come back when the xxlso modem is flashed.. And also not sure why it goes to unknown when any other modem is used.. Could there be any physical damage to the sim tray? Dropped the phone?
I have no backup of efs... I had one "nandroid" but deleted it after everything was okey...
I could delete the efs folder, so this unknown problem will turn a known one :victory:
I dropped the phone a very few times, maybe in one of those something broke a little and has increased more with the usage? (the disconnections from the network became spontaneus and progressively).
I found this other thread, I could try the same but I can't find the original GB firmware, every link I find is in hotfile.
Check in Samsung-updates.com firmware section. There are 2 GB roms there..
I found a efs backup from may 2012, probably auto-created when first installed ICS.
I flashed the stock GB rom and restored it following this tutorial for my .tar.gz file, but didn't work, so the device may be lost. I only have 3 more backups: boot.img, data.ext4.tar and system.ext4.tar. I guess they are useless to fix this...
Thay you for you support!
HELLO EVERYONE.
i have a samsung i9305T i flashed it wth L.P rom then suddenly
my imei went 0049. i tried anything bUt no luck. so i decided to flash a stock one
4.1.2 my imei was back. But when i try to insert my network sim it says.
NOT REGISTERED ON NETWORK . tho ived used this phone before here in the philippines
so im sure it is unlocked.
any help guys.? thank you in advance does my baseband caused the issue?
please help ...
Hi,
I'm not an expert at all but i have a theory :
I think you get a corrupted EFS. You flashed L.P rom so the format of your EFS changed to V2. So when you tried to return to 4.1.2, the phone can't read your efs anymore.
I think the solution is to flash a newer baseband, for example the L.P baseband or a KK baseband.

Hope it helps.
Hello, so here's my problem. After changing mainboard to another i9305 mainboard, i cant make phone calls or use mobile data (except when i'm on 2nd floor in my house or in very open area). All i know for now is new mainboards' imei and that there was i9305 xxbma6(Singapore) firmware. I'm from Lithuania. Please help !
For now i have installed XXUFNJ1 FW version Poland (nearest i could find to my country :/ ), rooted and ready for your solutions
Some pictures:
Please someone help me :/ i have tried to flash every single baseband from this site
http://forum.xda-developers.com/galaxy-s3/development-i9305/modems-i9305-cwm-flashable-modems-t2010116
But still no service.
have you checked if you have properly attached the antennas?
Hello
I recently lost my s10 and now got my hands on a new one (exact same model)
I thought i was smart and restored a TWRP backup from the lost phone on the new one
I guess the mistake was that there was also the efs partition included in the backup
The rom (newest beyond) works without problems but the sim card is not recognized and baseband and IMEI both show unknown
so i flashed the original samsung firmware with odin but even then i have baseband and IMEI unknown
Did i just screw my new s10 or does anyone have an idea?
any help much appreciated
Anyone has an idea what I could try?
Or did I really kill my phone for good
My guess is that you may have wiped out the new phone specifics, such as IMEI and other things. I'm not sure if you can recover that in some way, or if you need to just find a way to get your old IMEI back. I would probably try to restore my old IMEI if I can (see if you can identify the old one from your carrier's website or something, for example).

I know the original imei, it's printed on the phone but how could i flash that to my phone? Seems to be impossible
There are ways, but they are not allowed to be discussed here on XDA. I've seen Youtube videos that cover it as well.
