helo,
i am using samsung galaxy s2 GT-i9100
i flashed cm9 before and then i flashed samsung europe stock.
and now i see, my imei number has been changed.
can anyone help me to revert or change imei again!
Problem i am facing:
1.) call , message not allowed. (Gprs is working fine)
when i call, it says error "Mobile network not available"
i think its becuase my imei is changed to some europe imei now.
i want to get my real imei back , to make calls etc.
so, can u suggest me things to do?
did you make any efs backup? if you did then just restore if not... then it will be really difficult... there is few threads about it around somewhere in this forum ( seen it few times ) use search and i wish you good luck
ps. next time install ktool from hellcat and backup efs

I have a question.
My phone (samsung galaxy s2 gt 9001) has a generic imei, it is completely diffrent than original number imei under battery.
Phone works fine and I can make calls.
I want to flash phone to android 4.0 but I do wonder if phone will return to original imei after flashing (and let me do only emergency calls - original imei is probably blacklisted) or phone will still keep generic imei and allow me to make all calls.
thank you for your help
Did you make an /efs-Backup?
Did this happen after flashing something or...more information please!
You should always back up your EFS folder, which stores your original IMEI. I hope you did, have a look here anyway: http://forum.xda-developers.com/showthread.php?t=1264021
Chris.
You say your IMEI is probably blacklisted .
Stolen phone ???
A factory reset or flash of new firmware is always the first step to try EFS recovery so yes their is a chance of correct IMEI .

flash clean,stock firmware...an always backup efs folder tht is in good state...
Hello guys,
I`ve been watching all this topics for a while cuz I have some problems with my Galaxy S3. I`ll tell you what i did.
All worked fine, had the 4.1.1 official rom + root, then i wanted to go to 4.1.2 so i flashed an UK stock ROM. After that i kept getting the "Sim has been removed" error need restart bla bla.. so i search all around for a fix.. i changed 2 SIM cards and nothing. Then I flashed a Poland version 4.1.2 Stock. That version was better but I encountered the "Call ended" error.. calls would end after 3-4mins or i could not call at all. Then i flashed (and this is when the problem started) Stock Vodafone Spain and got "No network". I must say my IMEI/ SN all are intact.
Then I patched only radio modem from the UK ROM with Odin, but with "PHONE" option (i know i did wrong).. i wanted to change only the modem and it worked cuz i checked with *#1234#.. but from that moment not even one ROM has worked in showing me the network. On About phone says "Network: Unknown". Sometimes it connects to Vodafone but when I try to call says "No network service".
Now my phone is in second service and they can`t make it get a network on. They tryed the neverlock thing but i think was already unblocked.
I tryed rooting and using this Ariza. and were 2 versions there.. I tryed v5 only and didnt worked.
I tried the ##72786# and I get the following message: Connection Problem or invalid MMI code (found somewhere that for this code i need to have Wifi on to work?)
Now i`m thinking to get my phone back and dunno reflash with a good .pit file ? or just reRoot and try v4 Ariza.. I`m really sad, it`s been 5 days and I can`t think on nothing else to do.. I even called Samsung official service and they said to send it to them.
If you have any idea, pls need help. tnx
Check your IMEI is the same as under the battery .
Samsung will reject warranty .

you are right.. IMEI and SN are not the same.. pff what to do now?
Restore your backed up EFS folder.
jje
But i think i backed up the EFS folder with the modified IMEI. What can i do now?
nothing. replace the motherboard
SOLVED!
Ok so tnx to JJEgan i checked all the IMEI numbers and only 2 of them were modified. Thing is before I pached the v5 Ariza, I did a EFS backup with that program. That backup img saved my phone.
Firstly I got my phone back from service with 4.2.1 official ROM (thats nice, cost me 0 $ ). I rooted with CF-Auto and used Ariza patch (v4). But my imei was still wrong so after that I used EFS_Backup_Restore_new_ADB.rar to restore my IMEI/SN with the old EFS backup then I used another programEFS Professional v2.0. I checked the option to repair No network and clicked Restore. After that I restarted my phone and I got the messages from provider with APN settings and so on.
Thank you for the help :good:
worked till first restart... now No network again, I`m not a samsung/android fan anymore..
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!

Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
i have a sm g925f s6 edge which was working fine until about a week ago
after a restart I lost my imei and my baseband
which comes back after almost 6 restart and often after restoring the backup of my efs
ps: I have a backup of my efs
but every time I restart I lose my imei and my baseband
and I have to restart several times and restore my efs to hope to solve the problem again except that it does not work all the time
actually my baseband and imei are there so dontt want to reboot
if someone know whats is the pb if not i will to change the motherboard
