[Q] Problem with IMEI, SN and Network - Galaxy S III Q&A, Help & Troubleshooting

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

[Q] No service error

Hi guys
This is related to my brother's Galaxy S II. He had been using it for a couple of weeks when suddenly (according to him, wouldn't say if he dropped it or anything), he got disconnected from the mobile network.
He rebooted the phone, and got a no service error. When going into Mobile Network settings, it reads 'Insert SIM to access mobile network settings', even with the SIM inserted.
I tried his SIM in his phone - no luck.
I tried my SIM in his phone - no luck.
I tried his SIM in my phone - works.
Tried flashing two new ROMs - no luck.
I suppose this is the phone's SIM reader, then, but have you had any similar problems with it? Do you reckon this will be covered by warranty?
Thanks in advance.
You tried his sim on your phone and no luck? I thought you said his phone is the one wiyh no signal? Anyway, can you still see the imei on his phone?

Yes, I tried his sim on my phone too, just to see if the SIM was broken (which it wasn't). His phone has no signal, that is correct.
IMEI and IMEI SV list 'unknown' in phone info, but on the original boxing it's listed as 358150044627942.
Baseband also Unknown?
Maybe he flashed some custom Roms and lost his imei.

Yes sir, Baseband is also unknown. He wouldn't know how to flash custom ROMs, so I doubt that's the case.
Is this something we can fix ourselves, or would it need shipping off to service?
Thanks.
If you are sure that he doesnt flash any custom rom and only update with KIES you should bring the phone to Sammy support.
You can search the forum and find some threads were people lost their IMEI 'cause they flash custom roms. Then you can recover it when you backuped your EFS.
http://forum.xda-developers.com/showthread.php?t=1261948
But in this case you i think you havent any EFS backup.
My mistake: I had flashed LightningMod to his phone, but he had no problems using it after I flashed it -- the error only appeared after a couple of weeks.
OK, so seems like we're just gonna send it to Samsung, as I'm leaving the country on Tuesday anyway. Have reverted to stock rom and kernel, and I guess we'll blame it on KIES or something. Judging on our past experiences with Samsung it shouldn't be a problem anyway.
Please use the Q&A Forum for questions Thanks

[Q] Not registered on the network

Hi guys, i'm from Bulgaria and have a problem with my Samsung Galaxy S3 i9300.
When I put a sim card in and try to dial a number - "Not registered on the network".
I've tried more then 5 different roms (official from sammobile.com(4.1.2 and 4.3) and unofficial from xda forums 4.1.2), but every time pop up the error with network. Tried with Azrila patch and nothings goin' on.
I've tried to put another sim card and then error again. This and my sims are working in other phones normally
I've tried more then 10 time factory reset and so on.
The old owner of the phone probably was rooted the phone, because i've seen installed on it CWM 3.60 and android version was 4.1.2.
My IMEI and SN are correct in Android and on the label under the battery.
Now the phone was with official rom from sammobile 4.3.
The phone has no warranty.
Please can you help me to solve this bad problem.
Thanks.
IMEI blacklisted is most probable cause, followed by efs corruption, sim reader failure, wrong modem or other hardware issue.

IMEI, Baseband Blank/Unknown, No SIM Card Detected

Hello everyone,
I have Samsung Galaxy S2 international GT-I9100. It fall into water. After that everything working fine excerpt IMEI null/null, Baseband Unknown, No SIM Card Detected. I exhibited it and dryed for a month. When I compiled it up again, same problem.
After that I decided to change the moatherboard. I bought new one, change it, turn phone on and same problem!! After that I install new ROM via Odin. And the problem still exist! How this is possible?? Oh and I want to mention that I can't access service mode. When I try to access it service mode is opened but menu is blank!
What you think the problem is?? Maybe smaller motherboard, because the small one at the bottom of the phone I didn't change. I am very desperate after so many tries so please help me.
Thanks a lot
anyone???

most probably your efs folder is corrupt or some hardware faulty. Do you have any sort of efs backup with you ?
If you have no backup, you're probably boned. Download as many stock roms as you can & start flashing. If that doesn't work, take it to a local mobile repair shop; many have equipment which can re-write the IMEI to the device fairly cheaply.
Thanks for answers, no I didn't make any backup for efs, so today I will start flashing all available ROMs for my country if this will not work I will take it to the service.

I9100 No SIM card/no IMEI/Unknown Baseband

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!

No service, IMEI not lost. Data working

Hi,
Its been very recently that I bought SGS3 i9300 *exynos not qualcomm, in used phone and I'm pretty much in the dark what material does SAMSUNG puts into his phones to make them full of *beep*.
I was running XXELKC 4.1.2 firmware and I decied to just root > recovery > CM12.1 or CM13 SGS3.
Well everything went well but I ended up with no sim card error. Then I thought that might be my sim card is corrupted so I put in a newly replaced microsim card and put in the phone still no good.
Then I did wipe system+cache+dalvik+data and installed CM13 from TWRP. Still ended up in no simcard error.
Then I got to know about XXEMG emergency zip radio which is cross-efs compatible so I flashed that one. I ended up in NO IMEI/Baseband
I flashed XXELKC PDA file back and phone booted with its own IMEI number preserved.
Now I have working DATA connection but phone doesn't register on network for calls/sms.
What is the possible issue here?
I cannot find working modems link as the REF thread has dead link to modems.
I do not know how to fix this phone, and I've made myself a promise that this is my first and last samsung phone ever. Please help through this one for the last time, even it means working phone on a JB 4.1 firmware but I want the simcard/network/calls working to resell it and get rid of it.
Thank you for actually roaming around in Q&A section and taking a look.
Nobody?
