Hi!
So I have this problem with my Samsung Galaxy SII that it doesn't recognize the SIM card for the most of the time. When this problem started, the phone was completely stock (Not rooted/Not a single flashing made by me). Android version was the latest official 4.1.2.
Problem description:
I could be using the phone completely normally and then suddenly it reports that there is no SIM card. Now with pulling out and putting back the SIM card and rebooting couple of times, it might recognize the SIM card again and work for a while (few hours).
What I've tried to fix this:
1. Tried the SIM card on another phone, it worked perfectly.
2. Tried another SIM card on my S2, didn't work any better.
3. I thought that as the warranty is over, I might aswell just root my S2 and install the CyanogenMod 12.1 and check if this fixes the problem (Well it didn't).
4. I saw that my IMEI number shows nothing so I did this: [GUIDE] Recover your IMEI in 9 steps..
Well step 4 didn't bring back the IMEI number but now after rebooting a couple of times when I got my SIM card to be recognized again and then checked the IMEI, it was correct. Though the SIM card wasn't detected after a while again.5. Well now I flashed back the original Android 4.1.2 and checked the IMEI number (SIM not detected), it showed "null/null".
6. I went back to CyanogenMod 12.1 and saw that when it's showing blank IMEI, it's also showing "Baseband version: Unknown.
7. Flashed a new Modem+RIL, not helping either.
8. Tried many other things which I can't remember now but found by googling.
So it's sometimes working and also shows the correct IMEI and baseband and sometimes they are all gone?
My question here is that is there anything I can still try to get it working. And also if anyone knows where the problem could be? Is it some part that is faulty or is it the software that is messing with me? I'm quite handy at taking apart and changing the parts inside if that is the case. It's just that I'm not going to pay over 100€ for a new motherboard to get it fixed.
Thanks for any replies!

Ok, so to begin........ I had the power button problem on my Captivate as well as other problems, phone would get hot and smell and do weird things. So I decided to buy a broken phone off ebay and change out the motherboard.
I swapped boards and the new board had a lock on it so I couldnt get into the phone so I restored it to factory defaults. After that I was able to get into the phone and it works great except for the fact it will not connect to the network! So I have a camera and a wifi device.
Here is a list of problems I see.....
When phone boots up without sim card it doesnt ask for a sim card to be inserted
when sim card is inserted it doesnt read it (card and card holder work fine on other motherboard)
No network but wifi works fine
Baseband version - unkown
phone number - unknown
mobile network type - unknown
service state - out of service
mobile network state - disconnected
imei - unknown
imei sv - unknown
I have tried pretty much everything I have read on the forum....
Rooted phone and installed a custom rom and corn kernel - no luck
Mobiletechvideo method - no luck
moved efs folder from old motherboard to new motherboard - no luck
did a CWM backup on old motherboard and copied it to new motherboard and ran CWM recovery - no luck
tried Galaxy S unlock and no matter what I do only get the FFFFFF code
Flashed other modems - no luck
in hex editor my nv_data.bin files look fine.......
00188008|2e|34|00|00|00|00|ff|41|.4....A
00188010|54|54|00|00|00|00|53|47|TT....SG
00188018|48|2d|49|38|39|37|5a|4b|H-I897ZK
00188020|41|41|54|54|00|00|00|00|AATT....
So anyway, Im at the end of my rope so hopefully I can get some insight before I just give up (which I keep saying I'm going to do but havent yet, lol)
Thanks!
Hey everyone! This is my first post on this forum, although I visit it regularly. However, I have some major problems with my Galaxy S III and I've been trying to solve them since 3 days. Firstly, I want to say that I really did read most of the threads here, but I couldn't find a solution, so I decided to make a new one. So, my phone is not locked, but I realized that I couldn't connect to a network outside the country I live in. I use the same sim card which I use in my country, so I thought I have some roaming problems, because when I got back, everything was alright. I mean, I used my sim card without any problems immediately after I came back. Now I am out of the country again and I faced the same problem with my sim card, which is working on other phones. I tried other sim cards on my phone and I still cannot get into a mobile network. After that, I decided to look around the forum and I realized that I have updated to 4.1.2 two months ago and I probably have problems with EFS since I am with xxemg4 rom. I had an EFS back up on my external SD card and I tried to back it up using ktool, but without any effects. Then I decided to downgrade, I used different stock roms, even modified ones (such as MIUM and CM 10), but nothing couldn't help. Tried ariza patch, tried to patch the modem, tried "EFSv2 basebands" and they did nothing. Everything just got worse. My IMEI now starts with 0049, even my serial number is not the same. I tried to use nv_items_reader_writer to get back my IMEI but it doesn't recognize my phone. Then I tried to use the #7284# command, but my phone doesn't recognize it. I am out of ideas and I dont know what to do. I cannot take my phone to service, because I am not in my country and I dont have international warranty. I welcome every suggestion.

Did you flash any other modem with XXEMG4 rom? ....The modems after XXEMG4(along with xxemg4) reformats your EFS Partition so if you use any modem before XXEMG4 it will not be able to read your EFS partiton and thus your IMEI number also cant be read and it turns it to 0049 which is invalid thus you cant get any connection (mobile data/Calls/SMS etc)
What you can do is flash any modems after XXEMG4 or just flash the XXEMG4 modem itself ....that should reformat the EFS partition and thus your IMEI will be back to normal
Other than that what you can do is flash any rom after the XXEMG4 rom which again had the new EFS format in them.....samsung suddenly changed their plans and pushed these firmwares out with such a format
If you found this helpful why not press the thanks button

Hi guys
I have a big issue with my S3 GT I9300. This morning, everything was running well and suddenly i got the error message "No SIM card, insert a SIM card". I didn't try to flash any ROM, or put any root or something. I was on my desk, the phone was on the table and when i checked it a few minutes later : no network and SIM card error message...
Until now i was on I9300XXUFME3 ROM. I tried to clean the sim card, the sim card slot, push the sim card while the phone was turning on (maybe it wasn't touching correctly the pin), but still getting the same issue. My IMEI is OK, still the original one (no 00 or 0049, etc).
That's why i decided ot flash a orginal ROM and flashed my phone to I9300XXUGMJ9. Flash is OK but still getting the network issue (no sim card inserted)..
I couldn't try my phone with an other SIM as I was alone at the office but i guess the issue comes from the phone as my SIM card is not old at all (i have it for 6 months only) and I don't remove it often from the phone.. Until this morning, my phone (bought it from someone 6 months ago= was working perfectly and I didn't flash it since May 2013, so I don't really understand..
I also tried Ariza's patch (http://forum.xda-developers.com/showthread.php?t=1918601) but when I press "Apply fix", it starts downloading and stays at 0%.. Nothing seems to be downloading.
Any help would be very greatful guys, thank you.. :crying:
Don't go flash crazy, you'll do more damage with that patch.
Sounds like your sim card reader is faulty, not an expensive item to have repaired.

Hello,
I just went to an Orange store here in Paris and the issue was simply a deffective SIM card.. They replaced it by a new one and got the issue fixed
Thanks a lot guys for your kind help!
Hi guys, i have similar problem, i tried different sim cards, none worked, tried changing the whole card reader with a brand new one, but it didn't fix the problem.
everything started approximately a month ago, or even more, i tried rooting the phone after applying the update but i missed up and almost killed the hone, after allot of effort i managed to bring it back to life and re-installed the firmware update, but the phone started giving me the "Not registered on network" error, and the IMEI changed to that 0049 thing, then it started telling me to insertsim card.
the thing is, before all this happens I had no idea how to important it is to backup, so I have no EFS backup
so, any ideas what could be the cause? and how to fix it?
Hi mates,
Bought an second-hand D802 without checking the lock status. It worked when I tested it, but after a couple of hours it gave out the "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted". The phone automatically rebooted after 5 seconds and when it restarted it just said Invalid SIM.
It kept doing this many times a day. I needed to restart it 3-5 times to get it back with a signal.
Took it to a friend that has an Octopus Box, he struggled to Repair the security, even got the IMEI 0 but managed to restore it. Unfortunately with no success because the phone is in the same state. He software unlocked it again but with the same "Invalid SIM - Please insert a valid sim and restart".
I read throughout the forum that an EFS restore from another working factory unlocked D802 might get rid of the Hard Lock status, but no one confirmed a success for any G2 model.
Does anybody have the slightest idea of what can be done ?
Thanks!
Ok so I downgraded to 4.2.2 and now testing to see if the "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted" error disappeared. It displayed the first time I started the phone but let's hope it won't reappear. If in 2-3 days it will be all ok I will put out a guide for everyone that has this error with the G2.
Having the same issue. My phone is the d801. I had a backup efs but restoring it hasn't helped at all. Flashed stock kitkat rom and it worked for a few hours without the problem but now it's back up again.

I too flashed to 4.2.2 and it worked for a few hours but then started acting up again. Luckily after scouring for hours discovered it could be my sim card. Went and replaced it and now back up and running
but for anyone else there is a better how on returning to 4.2.2 than the one here on xda. Google pastebin Restore Stock G2 Firmware and there's a step by step with photos.
Ok this is whats happened so far.....
My daughters i9300 Phone's battery charge port was not working but instead of taking to it a shop to get fixed she purchased a faulty one off ebay to swap over the board.
But opening the ebay one it shows i9305 so I carried on swapping it over
After starting the device it shows i9305N on boot screen
Flashed a few Roms but each one shows *#06# : null/null
Sim not inserted so cant get into APN Settings

Have tried the one which was in her own phone but same thing happens
Everything else works fine apart fom this signal issue and imei
At first when I started the one from ebay up it was in Korean and I put her Sim card in it and it showed signal
So after wiping it and trying Roms I am not sure what modem or other files where in this phone
Is it just a modem issue or something else?
One which installed just now is I9305NXXUFNI4_NEEFNI4_4.4.4_KK Which I know is Nordic and I am in the UK
Have also tried UK Roms and same issue!
So does anyone have PIT,CSC files for Odin that I can try flashing and with Stable and preferably bloatware removed ROM
Thanks
Anyone?? tried new Sim Card slot and still shows this.....
