Hello.
I've tried to restore my original IMEI, since mine is set to 004999010640000, which is a fake. I've used repair application on Android Market and tried to fix it manually, but with no effect. It is still the same IMEI, regardless, what I do. I may be doing something wrong, but I am not sure. I run on ICS 4.0.1 and it is an original ROM. Rooted. Could you possibly help me with this case? I have an Internet connection and I can make calls, but IMEI is still fake. I also have power menu and lock screen working, so it is just matter of corrupted IMEI number, in my humble opinion.
I hope you help me.
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

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.
I have a stock Galaxy Note I717. I have not done anything to it as far as rooting or loading custom roms or such. A few days ago I no longer had any service. I ruled out the SIM card since it works fine in my wife's phone. I then noticed that the baseband and IMEI were unknown. I have tried factory resets to no avail and Keis won't recognize the phone so I can't get an update through that. I have seen other posts about reloading the EFS folder, but the problem is since I was not updating the phone at all, I was unaware of this folder. Any help would be appreciated.
Hi,
I got this phone from a friend and I don't know the history of it but is unable to detect any SIM card and the Baseband and IMEI appear as Unknown.
Do you have any idea on how to fix it?. Thanks in advance.
i had the same problem on 850FQ i bought few days earlier.
I digged deeper into the Issue and found out when someone wants to unlock their phone it can be done by 2 ways ONE: with an unlock code which people can buy from many online sites TWO: Using some hardware device i dont know its name. The repair guy told me sometimes a phones IMEI is also changed during the unlocking process and if the process is buggy then it may also damage IMEI AND BASEBAND.
Unknown imei/baseband can also be caused by a damaged "modem chip" or it can be caused by corrupt "EFS AND MODEM" folder while flashing custom roms. But since there is no ROOT and No firmwares available for the "A" model i guess your corrupt baseband is either due to "buggy unlocking" or it is a hardware malfunction. People who have the same problem in F or other models can try restoring factory firmwares with odin (from sammobile) but the folks with "A" Model are out of luck. i sold my phone as a demo unit cus i wasn't able to recover its baseband and imei.
Try a factory reset without simcard inserted, see if the imei comes back. if not you may sell it as a demo unit or keep the device for camera and music needs
