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

its not corrupted because everything is fine in JB 4.1.2 And I tried to use another modem and kernel in 4.3 but it didn't work
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.
Dude your answer is not good, its not my fault

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

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.

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

Nothing well....
I've flashed a stock rom MG4
After I've made root and installed Philz Revovery
I've installed BlackBox 1.3.1 but nothing changed
See my screen
IMEI is always generic and I can't use phone :crying:

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)

Hi, this two sensors just stopped working after update to 4.3. I've tried installing custom rom but still nothing. All my other sensors are working fine but theese two aren't giving me any data. Any help?
Factory reset and flash full stock rom with odin. If still the same then you have a hardware fault.

I've tried that but still not working. Do I need to downgrade to 4.1.2?
I don't think it will make any difference, but won't harm to check. Make sure you use an efs v2 4.1 firmware.

Now you lost me. What is efs v2 4.1 firmware?
Firmware EMG4 and later all require efs v2 format for the IMEI number to be read, by updating to 4.3 you now have v2 and cannot use a firmware earlier than EMG4, otherwise your efs (and IMEI) will be corrupted.

Flashing a 4.1 firmware should not corrupt efs, but only if you use EMG4 or later firmware. Anything earlier will not work.
Flash the full firmware with Odin, then factory reset. Backup your efs first.

I too have a phone with either 4.3 or was it 4.2.
Anyway can i downgrade it all the way back to 4.04, with odin (i have the firmware package downloaded from sammobile)?
Or is 4.1 the lowest i can go?
Thanks
If you go below 4.1 version EMG4 then you will lose your imei, also risk sds.

Oh. Bummer.
I actually seem to have just the 4.1 EMG4 installed now.
And of course no backup of 4.04 EFS.
So thats that then :/
(wanted to get back to 4.04 because it had T9 on/off button and "add word" option.
4.04 would kill your phone, not worth it for a keyboard.

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.
