Hi,
After using Android Revolution HD, I flashed back my original ROM. Now the phone doesn't register to the network and my IMEI number is 004999010640000. How can I get my old IMEI back so I can use my phone correctly?
I have to mention that I have no EFS backup.
Thanks in advance...
Did you read the stickies in general? I only ask because there is a whole thread about this.

One thing you can do to possibly recover your imei and network settings is to flash a stock rom that uses mg4 or mg2 baseband. use a rom from sammobile and flash with odin make sure you use a rom with an mg2 or mg4 baseband. good luck
make sure to read the stickies
Flash stock ROM, stock recovery, don't forget triangle away and give it back to warranty, I did this 2 weeks ago, and now my phone's fine (Don't forget and EFS Backup now)

Good day.
I was going back & forth from Stock & SuperNexus 2.0 just fine. Then I tried Android Revolution ROM, and now my problem is everytime I flash Stock or any other ROM, I can't text or call. The signal bar is fine. It's just that I can only make Emergency calls and it says Network Not Registered. But if I flash back Android Revolution, it's fine again. I've tried the clean routine (Factory Reset/Wipe Cash/Wipe Dalvik), still no luck.
Anyone encountered this before or any solution/suggestions?
Thank you.

is your imei intact? does it match what is under your battery? how about serial number? did you flash a rom with an mg4 or mg2 baseband? do you have a backup of your efs folder? read these before flashing anything further http://forum.xda-developers.com/showthread.php?t=2393289 http://forum.xda-developers.com/showthread.php?t=2377731
good luck!
Thank you for the reply. Im guessing that's what happened. But I will try to determine if my IMEI changed, so is my efs.
I hope there's a workaround and its reversible.
Thank you again.

if you did not back up your efs folder and if your imei has changed than most likely you flashed a newer baseband from mg4 mg5 or mg6 roms . and then reverted to an older baseband which can no longer read your efs folder. some people have been able to fix the problem by flashing once again an mg4 or mg5 or mg6 rom. perhaps doing this will allow you to regain your network connection and efs folder.
I checked. My IMEI and SERIAL Numbers are still the same with what's written on the back of my phone.
I've also confirmed on the Android Revolution HD 29 thread that it doesn't change the efs.
Any other ideas guys?
Thank you.

android revolution 29 modifies the efs folder so that it cant be used by older modems. it uses the mg4 baseband. since your imei is intact i am guessing that you are either back on android revolution or a rom that uses either mg4 or mg2 baseband as those are the only basebands that will work with the modified efs folder. if you still have no network but imei abd serial number are intact then check your apn settings to see if they are correct and compatible with your carrier

Android Revolution HD 29.0
--- release date: 31 July 2013 ---
•Based on latest official Samsung 9300XXEMG4 firmware
•Other minor changes and fixes
•Included and updated custom components:
I see. Yes, I am on AR29 right now since it's the only ROM I have that's has a working cellular network.
I made a recovery (cwm) backup when I was on SuperNexus, which I had no network problem with.
1) Can I extract my efs from there & flash that? Or...
2) Can I try and restore that backup without any major problems?
My ultimate goal really is to go back to my Stock ROM.
Btw, thank you so much for your patience Sir.
Sent from my GT-I9300 using xda app-developers app
cwm does not backup efs . for efs backup use hc-ktool from play market and efs pro. make backups and leave them on your ext sd card as well as your computer. you can flash any stock firmware from sammobile.com as long as the rom is in the "G" series. for example mg4 or mg5 or mg6. any rom from a-f will not read the efs as they all use older basebands. basically you cannot go backwards.there are many roms now that use mg basebands if you cant find one that matches the csc for your country than try any other firmware as long as it is a G rom or higher.
Very educational Sir.
Thank you again for your help.
It's much appreciated.
Good day.

I too use supernexus and stock. Also had this issue. You can still use any rom , you just have to flash a mg4 onwards baseband. For example, you can be on the supernexus ROM with mg4 baseband and you can make calls as usual.

No. I guess I'll just have to find ROMS with mg4 onwards. Stock or otherwise.

flash a stock f/w XXEMG4 or later via odin and then root it. then flash any custom rom via recovery(CWM touch or PHILZ). the custom rom(any AOSP rom)continues to use the same modem you have on the stock f/w.
:good:
Thanks I'll try to do it

when you flashed a custom rom you probably used a rom that included a newer baseband. Such as emg2 or emg4. maybe you did not have the correct apn settings and you were not connecting to your network . then when you flashed stock , perhaps you flashed and older baseband. that older baseband can no longer read your efs partition which contains imei and serial. a possible solution if you did not back up your efs folder is to flash an emg2 or emg4 baseband . or a full stock rom which uses an emg2 or emg4 baseband. all of this is explained in the stickies. the best way to learn is to read them. good luck
Ok.thanks. i wil inform

Hi,
I've got an Galaxy GT-I9300 and recently I flashed some custom roms, with no problems. But at the last time, my IMEI has changed to a generic and I received the 'Emergency Only'. Fortunately I had a backup of my original efs folder, made by KTool. So I restored it using some tutorials from xda and other forums and my original IMEI is back.
But it's frequently losing signal, then the signal returns with 'emergency', then gets normal, then lose signal again and etc.
My question is, can I restore an efs.img or *.tar.gz made by KTool using the EFS Pro? So I could wipe the efs folder and restore the backup, clean...
I'm now with WanamLite XXUFME7.
Sorry for my bad english :/
Thank you all!

Critical you read the first two posts .
I was using the UBEMH2, Omega Rom 4.1.2. When I flashed the Wanam XXUFME7 (4.2.2) it broken IMEI and got 0049..
Now it seems good, I haven't noticed no one or very few conection losses.
One more question, my counter is 1 and I have a custom recovery + custom rom. When I used Triangle Away to reset counter, even with stock recovery, the counter didn't get 0.
What do I need to do?

AFAIK this will happen unless you are running both a stock kernel AND recovery.
And how do I know if I'm with a stock kernel? Or by using a custom rom, the kernel is automaticaly custom too?

I had the same problem a few days ago when i was flashing cm10. Just restore back to stock firmware, root it and back up efs folder. then try to flash any rom and just restore the efs back up you did with stock firmware. it should be fine. if it is not working still, try to flash mg4 modem.
Thanks for your explanation!
Since yesterday it seems be fine, no more connection losses or 'emergency calls'. Maybe it was caused by a problem with my carrier. I'll keep it this way and if the issue appear again, I do what you said.
Can somebody help me with my last question, please?

Your efs folder is corrupt, pay for a repair or use a patched modem and kernel in 4.3

I get that update but when i update something happens if i backup my efs then if i restore would it work.
If you don't like the answer then fix it yourself, best of luck.

Do you know if your s3 ever had imei issues, got unlocked through means other than imei code, or did you ever used patched modem (or ariza)?
If yes, stay on 4.1.2, or do as adviced and get a patched modem and kernel for 4.3.
Your efs might be damaged, to stay on the safe side, backup everything before attempting to upgrade or patch stuff.
Ok thanks so do you mean by downloading another modem for my 4.3

Totally stock 4.3 need for GT-i9300 iv searched sammobile but there are so many I'm unsure, I'm in the UK and my device is unlocked, my problem no matter what I flash I'm getting no signal, imei and serial number intact and so is baseband thanks in advance
Sent from my GT-I9300 using XDA Free mobile app
Try the patched kernel and modem thread, if signal is restored with both flashed then you have issues in your efs folder.
Hey just looked but its pretty confusing to me, I have efs backup but no access to computer, was planning on flashing stock through mobile Odin
Sent from my GT-I9300 using XDA Free mobile app
In that case just flash the latest firmware, best do a full wipe including internal storage and preload first. Use Odin on a pc, mobile Odin won't flash all the partitions so you'll end up with some leftovers which might be the source of your problem.
Firmware
