Hi,
I have flashed about 50 different roms on my galaxy s3 and never had any problem with it.
Now suddenly when i flash a new rom i get the dummy imei 0049...... and i get blocked by my cell provider.
I flashed the stock rom and this helped to get my original imei back. So i taught well i can flash a new rom now maybe something went wrong. But again i got the dummy imei. So i flashed stock again and backed up my EFS. Flashed a custom rom and restored my EFS but i still get the dummy imei.
I really don't know what to do now. How can i flash a custom rom and keep my normal imei.
Already tried different roms and different android versions.
You were lucky the first time you switched to stock your imei got restored. You should've backed it up before hand. Refer this , it will help

Sorry to ask but, how do i do that? Is it this? http://forum.xda-developers.com/showthread.php?t=1506330
Ive flashed the AT&T stock rom already and it doesnt fix it
I had to do this the other day, for the same reason. Returning to stock Gingerbread from the link you posted did not restore the IMEI for me. However, I found a stock ICS .tar online that DID restore my IMEI: http://www.hotfile.com/dl/162779447/3bb6230/I717UCLF6_I717ATTLF6_ATT.zip.html
I did a full nandroid backup, flashed stock ICS and verified the IMEI had returned, re-flashed TWRP and made a backup of only the EFS partition, restored my full nandroid backup and then restored the new EFS backup over that. Worked great and I had almost no downtime.
Only issue I have now is flashing the GB modem sets my IMEI as 0. I normally wouldn't care, because I can still connect to everything, but Cerberus won't run without a valid IMEI. Restoring my EFS backup does nothing. Returning to the ICS modem restores the IMEI again. Blah.
still availible?
Do you by any chance still got the file, I have been looking for such a file like that, my imei shows null as well as the baseband does and i have tried every single modem or ROM i've found , had no luck, most of the roms will just reboot every 2 min on my galaxy note, but 1 stock ICS at&t rom, works perfectly but got no luck getting back my imei, would be so great if you could help.

Hey there people, first I wanna thank you for great community.
So I flashed a new rom (like i do every week ), of course I always have an efs backup (ktool and ARIZA).
this time after the phone rebooted the IMEI just didnt work,(exist but doesn't work), I've been contacted with the carrier and send the phone to repair.(and flashed a carrier stock rom of course).
they said the IMEI is "****ed up" and they changed it with JTAG, don't know about board switching.. they gave me the phone with stock rom so I flashed a new one, this time when I did the phone just gone back to the old IMEI (the one that doesn't work), I gave it back to them and they changed the IMEI again.
now I would like to flash a new rom and I dont want it to get back to the old IMEI..
you think if I'll back up the new IMEI and then flash the new rom (the IMEI will just go back to the old one) i could just restore it?
or is there any way I could flash a new rom without it would go back to old IMEI ??

Instead of bumping posts go to the service centre .
Your question and what's happened is beyond my understanding .
Only your carrier / vendor / Samsung can lawfully change an IMEI .

I know that, and I did.
I've been contacted with the carrier and send the phone to repair.(and flashed a carrier stock rom of course).
they said the IMEI is "****ed up" and they changed it with JTAG, don't know about board switching
now I have a stock rom and I'd like to flash a new rom, don't want it to go back to the old IMEI

Two choices one flash new rom or two dont flash new rom .
You say the service centre changed your IMEI so you now have a new IMEI .
jje
yes they did. I have a new IMEI, one that works but they game it to me with stock rom, I'd like to flash a new rom, and every time I do.. the old IMEI is being restored, my question is if I'll back up the new IMEI and flash a new rom (the old IMEI will come back) I could just restore it from back up?
I didn't find someone with the same problem

What JJEgan is trying to say, I think, is that talk of changing IMEI is taboo in these forums. You would be better off asking your service centre about the IMEI reverting to the old one after some time. Not about the custom ROMs of course.

Yes in a way IMEI is not a topic that can go to far .
Real reply is the IMEI has legitimately been changed the user is looking for another user with the exact same situation i guess . But their is none so he bumps and bumps posts .
Why the f*** would old IMEI come back if its been legitimately changed .
So as i said flash your rom or go back to the service centre to clarify .
END.

Hi all. I rooted my phone couple of weeks ago and I didn't like the rom that I flashed and I decided the unroot my phone. So today I tried to unroot my phone and applied triangle away solution. Everything went perfect. I flashed a stock rom, I unrooted my phone successfully. Since this I have no connection at all. No 2g, no 3g. I've done some research on the Internet but couldn't find a proper answer. The phone shows the imei number but it doesn't match with the number under the battery. What should I do?

As per the faqs and guides restore your backed up EFS folder .
Not read the basics and no EFS backup then its a paid for service repair.
jje
I have no efs back up. I rooted my other phone million times but I've never backed it up. So jje you basically mean there is no exact solution for the issue. I need to send my phone to the service?
If you flashed a custom rom it may have a EFS backup look for EFSbackup.tar on your phone .
Looked for it but there is nothing. I've sent a PM one of the XDA users who is an expert with IMEI. I'm waiting for his answer. If he can't fix it I'll visit a Samsung repair centre. The phone is now out of warranty, isn't it? How much they are gonna charge me roughly?
did you try to flash an emg2 or emg4 baseband? some have reported that this can restore network connection

You are amazing mate. Your suggestion fixed the problem. I now have 2G, 3G connection on my phone. Thank you so much.
make sure that going forward if you flash any other baseband or rom that includes a baseband as all stock roms do and also some custom roms as well, that you flash one that is newer than what you have now. the older basebands can no longer read the efs folder because beginning with emg4 the efs folder is modified so older radios will not work properly. back up your efs folder because it may get corrupted. if that happens than only a backup can restore your network connection, this time you got lucky it was not corrupted yet. the format changed but the info was intact. please read the stickies all the answers are there.

Dear Ashraf sharif,
My sgs3 gt i9300 currently has baseband version I9300 DDEMG2 and bulid number JZ054K.I9300XXEMG5.
I had flashed resurrection remix rom and i got my IMEI changed and baseband version unknown then i restored everything back with a lot of help form rootsu,now my issues are:-
which all baseband i can flash or which roms are suited for this ie what should i look for in a rom while flashing as far as baseband and not ****ing up my imei is concerned?
and does that means in addition to flashing a custom rom i need to flash a baseband also as you mentioned that few custom roms have baseband ie all doesn't have basebands???
thanks in advance.......
I am no expert on this issue as I have not experienced it myself. With that being said , it is my understanding that once a g series modem or baseband is used reverting to an older baseband will result in no network. Read the thread in general called " attention 19300xxemg4 changes efs folder". some firmwares do not touch the baseband only affecting system+ kernel+ recovery.
Since you are on mg2 baseband it is probably safest for you to stick with it because it works . If you do decide to change it make sure you flash a baseband that is either the same or newer. Also make sure csc code is correct for your region.
Make several backups of your efs and save to external sd and computer and flashdrive. Read the stickies .
wait and see before flashing . Read reviews for newly released firmwares. This is how I avoided this relatively new issue with efs imei . I simply read the thread "attention 1900xxemg4 changes efs folder.
Hello All.
I have a Samsung Galaxy S3 international (GT-I9300 - OS 4.0.4 - I9300DXLE8 baseband) I applied a ROM update (4.2.1) and lost signal. I then flashed again using various ROMS but nothing. I did some research about the EFS folder and using the XXEMG4 modem binary to get the IMEI number back from the generic one but now I cannot connect to any of the mobile carriers that are found. I have to admit, before I discovered the XXEMG4 issue (from a thread here) I did (mistakenly) look in to the EFS folder and I confess I most likely have messed that up and that may be the reason I cannot get a signal any further even though I can get the correct IMEI?
Is there anything I can do which would not involve sending the phone to Samsung? Flashing the stock ROM did not fix it and now, I have found, regardless of what ROM I flash, I must also flash the XXEMG4 modem as well otherwise I just get a generic IMEI number. I blame myself and my own stupidity for not reading more about the EFS system first (and not making a backup either) so I just wanted clarification that there is nothing more I can do.
To summarise:
Updated ROM and lost IMEI (generic)
Did not back up EFS folder
Flashed various ROMS - no service & generic IMEI
Flashed ROM with XXEMG4 modem
Phone IMEI is correct but still no service - emergency calls only
Ariza patch did nothing, factory reset does nothing, stock ROM does nothing.
Many thanks for your time.
Install the patched mg4 modem and all should be fixed

Start from beginning flash leaked firmware via odin from sammobile
Then root by cfroot
Install recovery and then flash custom recovery..
Also if u do have a backup of stock with working imei then u cn restore that if u dnt want to do the odin procedure..
Thanks for the replies but I seem to have fixed it.
I restored back to stock ROM, restored EFS Backup using KTools and restarted the phone and all is well.
I am now backing the phone up completely using EFS Pro.
Many thanks.
If you've corrupted files in the efs folder then no, there is nothing you can do yourself. The repair should not be too expensive as no hardware needed replacing.
Edit. You wrote 'didn't backup efs', but now say you've solved it by restoring your backup -which is the whole point of taking a backup before you flash anything.

greetings, ive read several threads about the IMEI and efs thing but unfortunately i havent found a solution for my problem yet.
I´ve lost my IMEI because i deleted my efs folder from the root folder of my phone (galaxy s3) and i had no backup. Someone restored the IMEI with Zbox or Octopusbox (not sure which one it was) and everything worked fine. So i made an efs backup and flashed Cyanogenmod, but after flashing the Rom my IMEI was lost again (0049...) and the phone couldnt find a network. Restoring the efs backup did not work and so i had to go back to stock and let the guy restore the IMEI again.
And here comes my question: I am currently on stock rom with rooted kernel (havent flashed any rom since the second restore because i dont want to risk losing the IMEI again) and i really like to change the Rom because you know stock rom is kinda bad. Does anyone have a clue what i need to look out for or why my IMEI gets corrupted on flashing another Rom?
What version of firmware did it come back from the repair with?
Usually a poor repair will install an older firmware, with efs v1, as boxes won't work on v2. Trying to update to a newer firmware, v2, will corrupt the imei.

the firmware wasnt changed at all, it was UGMK6 stock with CF-rooted Kernel. the IMEI got restored via samsung tool on my pc and it got connected to the box via UsbOverEthernet client. The console only showed like:
-checking root access
-writing IMEI to phone
-patching modem
-ok
is there a way to check if i have efs v1 or v2?
