I9000XXJPC has become a major headache, and now the sim card won't work with other firmware. The first time I updated via Kies, everything was fine for a little while. After realising it's buggy, I went back to JG4 and renamed nv_data.bin etc..
The second time I installed JPC for a bit of a play around was via Odin, and that went fine, but still buggy firmare. This time when I went back to JG4, the sim card doesn't work properly. It asks for the PIN, sits on "Unlocking Sim Card" for a bit, then asks for the PIN again, saying it's incorrect. After entering the correct pin another 2 or 3 times, TWlauncher appears, but there is no service.
Odin didn't make a backup of nv_data.bin, but I had made a copy myself just in case. Restoring this does allow Kies to see the proper product code, but makes no difference with the sim card.
Is there anything at all I can try? It seems as though flashing JPC via Odin has altered more than just the /efs directory, but I don't know what. It might also be possible that anyone else on JPC will discover the same if they go back to 2.1, but I hope it hasn't done too much damage. I tried another sim card from another network and it's the exact same situation (works only with JPC).
To anyone who hasn't tried I9000XXJPC, don't! It's not worth the hassle.
Basically, sim cards now only works with JPC..what can I do? I have 3-button recovery, so can try just about anything if need be.

Thanks, I read and tried so much but somehow missed that. At least it's a known problem thanks.
Edit: I thought it had something to do with the dates of the files. hmmm now I'm stuck.
Dear experts, I need your help please!
After years of flashing and enjoying the know how in this forum, I got into serious trouble for the first time.
I flashed ICS333, and I guess, my IMEI was lost (0049...). But everything worked fine, so I didn't fix it. After a few weeks I got the known FC-bug of the ROM and reflashed it. The phone boot looped, so I had to do some wiping and reflashing. When I managed it to boot again, it didn't recognize my SIM card anymore, just as if it wasn't there.
Here is what I did already:
Checked the SIM card with another phone: Works fine.
Flashed a stock rom on SGS: SIM still not working.
Restored IMEI via Nitrality. Got a "new" one, different to "0049", but: SIM not working.
Erased the nv-Files in the EFS-Folder. Product Code is VD2 again. It was KOR before, and should be correct now as I am in Germany and Vodafone-Customer. But again: No SIM card detected.
Followed the instructions in the "Restore your IMEI"-Tutorials, even though it is restored already. Used Terminal, BusyBox, Ghost Commander. Didn't help...
As you can see I tried EVERYTHING I could find on the net in the last few days, and I am really exhausted and clueless now. Can anyone help me please!?!?
Please erase this thread. During all the IMEI- and country-code-trouble (that really occured, I swear!) I fixed the problem without knowing it. Because I inserted the SIM the wrong way constantly. This is sooo embarrassing. Shame on me for steeling your time! :/
Thanks for the laugh, this is highly amusing!
THANK YOU!!
I mean literally!! I had exactly the same problem as you! Never would've noticed it if it weren't for your story!
although i feel a little stupid right now
Please help
i have the same problem only i cant fix my imei, after flashing the phone it changed to 00499.. it made no nv_data.bin.bak
If the efs folder havent been backed up, what can i do? I tried changing the nv_data file like some tutorials here explain, but no luck(tried couple of times, it defently not compatible with my galaxy s3), i believe these tutorials are for erlier galaxies.
Please help!
Thank you

Hi there,
I am by no means an expert on any of this, but I've come across an issue what makes my phone unusable even though I have only had it for a month or so.
After getting the phone, a friend of my flashed Slimrom (version 1) for me on my phone. I've flashed myself before, but I had no idea how to get the device rooted for me. That went well untill I got a message of "full storage" last night, even though there was about 60% empty internal memory left. After some moving around I decided to factory reset, and when that didn't work reflash the ROM.
The issue seemed resolved however for some reason my phone no longer recognizes my simcard. My simcard still works (tested it on a different phone) but it never asks for either the pin didgets. If I try to go to to mobile services it just says "error could not find any mobile networks" and even after flashing the newer rom Version 2,5 and now flashing CarbonRom I can't get it to work!
I am left clueless, if anyone could help me out it'd be great as I am really dependant from this phone!
You have a so called developer IMEI now (starting with 004999...). Please check this.
This is the reason why the sim card isn't recognized anymore.
You can change the simcard pin after each restart and it works.
Or use one of my Roms with a workaround (I have this IMEI problem too).

Thank you so much for responding! If I try to retrieve the IMEI by typing in: #*06*, all I get is a blank. I however was able to find it with a sticker inside the phone. I guess there isn't a simple command to getting this changed. I can't even find the simcard pin change in my settings, it's not in the security tab atleast.
I will do anything for a ROM right now just to be able to get my service up and running, but I'd like to fix the phone for the long run. Any idea on how this is best achieved?

Blank ist the other version of a ruined IMEI.
Search here in the forum: there are some threads regarding backup of EFS and restoring IMEI (if you made a backup before).
And one member is offering to repair the IMEI if you can proove that you have the original (the sticker). See his website http://www.cvxcvx.pl/?lang=en
Alternative: try my Pristine XXLSZ v1.9 with the workaround I use all the time without problems. After you can be sure if it is only the IMEI problem or something more difficult with your sim.
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!
Dear XDA I9070 experts I really need some help here.
First I want to apologize if I have some errors, my english is not very good, so sorry about that, I will try to do my best to explain and give the best background information if anyone can help me.
My actual phone is an Motorola Atrix 2, and I have flashed roms several times following the procedures explained on the threads here in this awesome site XDA step by step. So being able to flash roms with no problem at all I tried to do the same on my wifes old Samsung I9070.
I followed a thread that explained how to flash a ROM from GB to Kit Kat for the I9070 step by step here on XDA. The thread is this one:
http://forum.xda-developers.com/showthread.php?t=2198341
It all went fine but being that the phone was not being used by anybody I forgot to insert a SIM CARD before the flashing procedure. I really don't know if that makes a difference, but when the mobile booted the first time after the ROM flashing I inserted my SIM card and to my surprise I didnt recognized it... booted the phone again several times and nothing, but the SIM card is being detected right away on my Motorola.
So I tried to do some research about that and some people suggested to go back to stock firmware, and others told that it was a problem with the EFS folder.
So I tried going back to stock JB with ODIN, but this time with the SIM CARD inserted, and nothing, the same problem. So I tried inspecting the EFS folder and I think that is the problem but I need some advice on this.
The EFS FOLDER has this content:
A bunch of files named CRYPTPROP...
DECRYPT_KEY
ESSIV
GUARDFIL
NV.LOG
NV_DATA.BIN.MD5
And some folders inside... Thats all. I didnt made any backups of the phone or the EFS folder
So I tried using the code *#06# and it gives a valid IMEI 3544******* etc
I really don't know how the phone still shows a valid IMEI with the file NV_DATA.BIN missing, so I checked the phone information and found this:
Inside SETTINGS:
MODEL NUMBER: GT-I9070
ANDROID VERSION: 4.1.2
BASEBAND VERSION: I9070XXLQL
KERNEL VERSION: 3.0.31 - 1485715
BUILD NUMBER: JZO54K.I9070XXLQL
Inside SETTINGS - STATUS:
NETWORK: UNKNOWN
SERVICE STATE: OUT OF SERVICE
MOBILE NETWORK STATE: DISCONNECTED
MY PHONE NUMBER: UNKNOWN
IMEI: 3544******
Maybe the EFS folder is not all bad, I really dont know, please I need some advice here. My motorola screen is dying and I need to recover this one as it is a good phone. Thanks in advance for your help.

Your baseband is not missing, but anyway you can try this: http://forum.xda-developers.com/showthread.php?t=2677807
P.S. And you did factory reset after going from GB to JB?

I followed all the steps and still No SIM... Insert SIM card message :crying::crying::crying:
And to answer your question... yes I did factory reset several times... wiped cache, everything... several times after flashing :crying:
Any other suggestions?, I really don't know what else to do... thanks in advance for your help and time.
What JB rom did you flash? Link? Perhaps any Baseband problem ... and where are you from?

Thank you Flo0008 for you help... I used a firmware from Sammobile... this one exactly I9070XXLQL_I9070ITVLQ5_ITV as it was one of the more recent ones.
By the way I'm from Venezuela, but I bought the phone new and unlocked from amazon, the phone is in mint condition and my wife used it for more than a year without any problems, also we use the same carrier... it was not used anymore since December 2013 and recently I charged it for a full battery and did the firmware flashing and since then I'm facing the No SIM card, Insert SIM card message.
Could it be the firmware I selected I9070XXLQL_I9070ITVLQ5_ITV the problem?... It's from Italy... maybe you can recommend using another one.
Thanks in advance!
I had similar situation once when I tried different SIM card. My solution was to put SIM a bit twisted into its bed.
[\] instead of [|].
It took few tries but finally it got detected and working.
Sent from my SGS Adv. using xda-developers app.
most likely your phone was *not* SIM unlocked before you flashed it: I did the same thing to mine and read many similar stories here and there.
I never found a solution and bricked my phone while trying to fix it. I went up to copiing a full ROM dump from another working 9070P: the copy succeded and phone worked (IMEI cloned etc...) but still no SIM card recognized (it was a spare free one so not a problem
If I manage to achieve my unbrick procedure (http://forum.xda-developers.com/showthread.php?t=2701363), we might be able to fix that by reseting the full ROM to a valid state.
Facing the No Sim issues
i am facing the same problem, and it was all of a sudden."No SIM"
I sent the phone to service center, but they failed to repair.
i have tried everything, hard reset, downgrade to GB, upgrading again to JB (via ODIN), custom ROMs, but no luck.
what i figured out is my phone works on some older SIM cards, which have square shaped Chip (like the one in BSNL sim).
any suggestions????
