Did you have EMG4 at any point?
edit > Pardus is EMG4,
Have you still got the MG4 baseband?

Baseband = modem = radio.
it MUST be MG4 on an MG4 ROM. Pardus comes with MG4 baseband. Did you flash another?
Ariza is not a baseband :/

Be explicit please. Was it mg4?
If it was mg4, you need to send for repair

I don't know was it mg4 I buyed the phone couple days ago, and then i flashed leaked 4.2.2 firmware, then i installed pardus rom then i noticed no network, and when i look at my IMEI 0049 first 4 numbers

The thing is mg4 baseband changes format of efs folder. Pardus is mg4. So now there are 2 choices...
1) restore efs (not option you said)
2) ensure you have mg4 baseband.
Once you have flashed mg4, mg4 is the only baseband that can read efs (and in turn - imei).
So make sure you have mg4 baseband
If you do have mg4 baseband already and imei still gone, you need to send for repair

Don't flash anything until you take time to read the faqs and guides .
basic knowledge is required ignorance just leads to a bricked phone .

And back up your efs now, today, to three different places, then back it up to two more to be sure.

No network connection after custom ROM install

Hi,
I was trying some different ROM's on my i9300 (UK 3 network) and had various problems with all of them but eventually decided to stick with Omega v46.1 Jelly Bean 4.2.2. All seemed to be good last night in the house but today I can't connect to the network (wifi works fine). I tried restoring a backup and re-flashing to stock (using Odin) but I still can't connect to the network.
Thoughts?

Apn correct? Does the imei match the sticker?
What was the last rom you had that could connect

Ok. I believe pardus uses XXEMG4 as a base? Could you check that please?
If so read the imei / efs thread linked in my signature

And yes Pradus does use XXEMG4
Given I don't have a backup of my /efs what are my options?
As per the thread, you have 2 options.
1) go back to pardus
2) locate an mg4 baseband and flash it

Thank you kangerx, so basically if i install a MG6 ROM i have to stick with it or restore from backup right?
No, you can use any rom. You must stick with an MG baseband or newer

Network Not Registered on Stock or other ROMs besides Android Revolution HD

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.
Sent from my GT-I9300 using xda app-developers app
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.
Sent from my GT-I9300 using xda app-developers app
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.

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:

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

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.

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?

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.
