You Flashed DEVIL KERNEL?
If you did http://forum.xda-developers.com/galaxy-s3/orig-development/kernel-devil2-2-3-2-omni-cm-samsung-t2528624 the first flashers LOSE Their baseband too.
Try to read the thread on how they fixed the problem. Are you running on CM? Dual Boot?

Bump for me

Flash the full stock rom for your country with Odin then factory reset in recovery. If efs is not read by the stock rom then restore your efs backup.
No backup then you'll have to pay for a repair.

If your IMEI is 0049 or null, try to use a patched MG4 modem first. Revolutionary roms don't have modem in them so that can cause some issues occasionally.
Let me know if it works.

Hello There,
I think the problem is the rom itself, i advise you to degrade your phone to its stock rom/orig rom and find a better rom.

Well my IMEI seems to be normal,it is not recommended to post it here?
Ps there is a way to find what was the original ROM of the phone?
Ps the imei shown on the phone is the same of the one shown on the back of the phone
Is this a good thing? Means no corrupted imei?

- I would recommend never to post imei anywhere
- If the imei matches then all's ok.
- Stock rom depends on the country. You can search on sammobile and flash with Odin. 4.3 not recommended if you like flashing roms.

What i can do to restore network?

I advise to flash patched modems
You should try 2
Before mg version and after mg version
To check work both efs versions
If you don't know about efs stuff I advice to read imei thread in the sticky. Good luck with flashing modems :good:

[Q] GT-i9300 imei null/null, unknown baseband

I have an i9300 with a blank efs folder. The phone corrupted and was stuck in a boot loop. This happened when battery run out while file sharing was in progress via bluetooth to another android samsung. I flashed it with 4.22 android jelly bean immediately XXUFME3 but it remained stuck on boot loop, I never backedup efs file. Later found the original ROM although it comes up as custom rom, which is i9300XXEMB5_i9300OXAEMB5 but still no luck as it stuck in boot loop. My sister has the same identical phone both were purchased together in Dubai. I did factory reset etc, no luck still in boot loop.
I later gave it to a mobile shop who flashed it with a rom for free, didn't charge me because it came up as imei null/null and baseband unknown. The phone now boots and has Build number of IMM76D.I9300BUALE6 and is german language I believe. I had read some threads by now and I immediately rooted the phone and backed it up, but my efs folder is blank.
Last night I flashed the phone 2 times with i9300xxemb5 rom and rooted it and it still boot looped even factory reset or cache delete don't solve boot loop, Then I restored the working rom of build i9300BUALE6 from CWM and powered phone on and got a baseband of i9300XXEMB5 and Build of i9300BUALE6 also got an imei of 004999xxxxx0000/01 and the phone found the network and my efs folder which had been blank all this time was full of files. In my haste I realized the sim was not plugged in and removed battery, when I restarted with sim, baseband was gone and imei was null/null. I repeated my steps in hopes I could get this fluke opportunity but nothing yet. Was this a miracles I didn't seize by not backing up the efs folder?
My sister's phone is an identical model bought together with mine is,
AP:i9300xxemb5
CP:i9300xxemb5
CSC:i9300oxaemb5
So my question is I need the original stock rom for my sisters phone that won't get stuck in a boot loop on my phone
My phone is now
AP:i9300buale6
CP:unknown
CSC:i9300vfgale6
Also can this be fixed by backing up my sister's efs folder or backing up her phone and flashing it on my phone. I can't get warranty for this phone now since it has binary counter of 12, don't have proof of purchase and also I am not in Dubai but in Africa. What Rom file should I try to flash. Also because this is a custom rom I am not getting samsung serial port in device manager can't use NV writer. Any help is appreciated.
If you don't have an efs backup then you need a service centre, you cannot repair it. Trying to use another phone's efs folder won't work and is illegal in many countries.
Read the sticky on efs:
http://forum.xda-developers.com/showthread.php?t=2393289
If its a custom rom their is a very small chance that it included backup pf EFS .
Look for EFS tar file on phone .
I say slim chance and judged by the OP probably no chance .
004999xxxxx0000/0 that's just the generic non working IMEI .

Sorry to hijack this thread but I dropped my S3 i9300 on water and have the imei null /null and baseband unknown problem, therefore SIM cards are not recognized. Do you think my problem can be solved by doing something without taking it to samsung service? Meanwhile I ordered a SIM /SD tray replacement but my bet is it won't solve the problem.
Thank you.

hi from what you explained it seems that right now your phone has no baseband. 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

A custom kernel has no connection with the lost of IMEI or it's a solution for the recovery of an IMEI. So no, no custom kernels will help you with your problem.
Either try ashraf's suggestion or ultimately bring it to a Samsung service center for repair.

You can try but i doubt that it'll restore your IMEI. If that doesn't work then you have no choice other than to bring it to Samsung for repair.

I don't know about perseus kernel but I don't think it will help. your imei and efs foder was intact before flashing4.2.2. I understand that the problem began before flashing 4,2,2. but if you ever had a rom that used an mg4 or mg2 modem and then used an older modem your phone would lose its network connection and would probably display a generic imei number. if it says null usually that means it is corrupted or no modem is installed . either way if you send to service center you need to flash a stock rom and reset your flash counter . since some people have recovered their efs and imei by flashing newer modems or firm wares that use them why not try it before sending phone to service center

Thanks but you didn't read my first post. I did not flash any rom (or even root) before the problem, which started from dropping the phone on water...so I have no warranty left This means I can take the phone anyway I want (custom kernel, rooted) to samsung service cause they will charge me anywat.
But I think I will try to flash a rom like the other user sayd because I flashed the Perseus Kernel and the phone is now unstable and reboots randonly...
Cheers
my mistake that post was for the op of this thread
I don't care anymore that my original answer was
deemed not acceptable enough and warranted a second opinion. I am once and for all, going to put this nonsense to bed.
If you lost your imei because you submerged your phone in water it is a hardware issue. It is INCONCEIVABLE that flashing a rom, kernel or baseband will restore the imei. A SOFTWARE solution will NOT repair DAMAGED HARDWARE. This is obvious!
If your Blu ray player cannot read disks because the disk tray fell off, upgrading the laser driver wont help. This is exactly the same.
Depending which hardware failed, replacing the tray may help although given the symptoms, it seems much more likely that your radio stack is damaged. Take it somewhere to get it repaired and stop wasting time pretending software will fix your issue. It's IMPOSSIBLE

by highlighting i want to emphasise these points (do let me know have i understood correctly)
1) i'm on stock XXEMG5 and yours is MH1 which means yours is ahead of mine and how's it better or it's just region specific???
2)you are on MG2 baseband/modem does that means you also have to be restricted to MG2 baseband/modem only when flashing roms????
thanks in advance.....

I see you're still struggling to understand this.
2) If the ROM is MG (M = 2013, G = July) or Newer, the ROM changes EFS format. This means if you flash one of these ROMs without backing up your EFS, you are restricted to using an MG modem or newer as only Modems from July 2013 can read new EFS format. I'm really not sure how I can make this any simpler to understand.
However, if you flash the modem separately from the ROM, EFS is not changed. So for example, if you are on ME7 ROM, you can flash MG2 modem without affecting EFS.
I hope this is clear now.

Dear rootSU,
you've been very patient with me and i really appreciate your efforts at making me understand and i've understood a lot because of you only,but what puzzles me is that
1)this restriction is for those who've not backed up EFS whereas in my case i had in the very beginning only made an EFS backup.
2)and if i flash ME7 ROM then since am coming from MG5 to ME7 my imei would again be corrupt and i'll have to flash MG2 baseband...right??even if i have an EFS backup(EFS PRO won't restore my imei in this case despite a backup)?
thanks in advance

[Q] Galaxy S3 - Android revolution V32 - How to fix signal problem ?

Hello everybody,
I don't know if I am in the right section to post but I can't post something on the topic for the android revolution rom.
I was on a stock rom XEMG4 and I install the android revolution V32. I think the Rom is perfect but useful for me because I have no signal !
I've put everything in the APN.
I don't know how to fix it ?
Sorry for the English I'm from Belgium.
Thx for help
Please check your IMEI no. If it is the same as of the one on the box. and did you flashed older modems?...

that's actually downgrading you have done! the EFS versions do no match and hence no signal. go through the link under my signature!
I have done a mega wipe so I think I loose my efs and don't have done a backup.
I reinstall a stockrom and with this one no problem of signal but when I reinstall the Android Revolution ROM no more signal...
Do I install Android Revolution and after flash the EfsV2 on my SGS3 because I'm on a EMG4 stock rom ?
I root my phone and install es explorer and i see that i have a file efs but nothing in.

I don't think so, I just install the rom like explain in the tutorial of phonandroid (French site)
what happens is the ROMs after MG4 changes the EFS partition format so the older roms cant read efs partition if you roll back to older version of the roms. that is the only thing I can think of... Or otherwise your phone might be SIM locked to another network...

Looking For 4.1.2
In fact I was looking for a solution to switch back to Custom 4.1.2 as it was the perfect ROM so far for me.
I have downloaded it from Sammobile but after Installing it via Odin I am unable to see any network and the Phone's IMIE is changed. I would greatly appreciate anyone to come up with solution for that....

With suggestion of a good mate, I am finally able to go back to 4.1.2.....
All I had to do was just Install the Patched Modem MG4

Dear friends I recently installed I9300XXUGMJ9_I9300VFGGMJ5_VDI_2.tar (Android 4.3) on my Galaxy S III International version. But as we know the firmware is full of messy bugs I just installed the old 4.1.2 firmware from Samsmobile and kies too.. But the problem is that I can't access my network. There seems to be only emergency calls... Can you guys get me this problem fixed? Is there any way to downgrade my phone to old 4.1.2 Jelly Bean. I desperately require some help.

Check your IMEI number, wheather it was changed to 0049XXXX - I have had the same problem. I downloaded from Sammobile firmware v4.3 and flash your phone with odin. My IMEI and network connection was restored. Looks like Samsung does not like us to downgrade the firmwares.

Its not a problem if users care to read the faqs and guides first .
Solution.....
Hello guys....
I am very thankful to the xda forum and all the members who helped me to get through a serious problem..
Recently I installed 4.3 Leaked version on my GT-I9300 and the ROM proved to be worst ROM of life. So I decided to go back to 4.1.2.
I installed the custom ROM via Odin but I confronted a serious issue, when I was finished the installation I found that there was no network at all... Samsung's official told me that it is impossible to reverse the Android version...
I had no clue what to do. I flashed many ROMs but no solution at all. My IMIE was also kinda jumbled..
Many guys said it is EFS issue... But it is not EFS issue...
It is all because of different Modem issue.. all you need to do is just install a clean custom ROM from http://www.sammobile.com/firmwares/2/ and Install the patched modem... you are done..
So here is the solution:
1. Download your desired CUSTOM ROM for your Country from Sammobile...
Link http://www.sammobile.com/firmwares/2/
2. Install the ROM via Odin
3. Root it and Install your favorite recovery.
4. Install the Patched MG4 Modem Zip in Recovery Mode. Link https://www.dropbox.com/s/geispctijp...9300XXEMG4.zip
You are done....
This problem is all about MODEM version, so I don't think if EFS tricks are involved here.....
Finally credits go to all the XDA Members who put their heart and soul to present all the required guidance for me to be able to downgrade to lower Android Version.. I have only compiled the whole stuff into a single thread....
Thanks,,,
Plenty of solutions....

Dear sir,
Actually the problem is not finding the solutions but finding the right solution.
Worth members of XDA Forum post a lot of solutions for a particular problem and thus newbies like me get even more confused... So it definitely takes some time for us to come to a point when we are able to get the desired results.
Sometimes, we are not able to clarify our queries.....
As in my problem only a Modem was required while I was looking for EFS solutions!
After Flashing the MG4 modem my battery life has become worst. I don't know if it is because of the Modem.. but whenever my phone is on airplane mode then the battery remains at the same percentage but while on network my battery keeps on draining without even texting or calling

[Q] After flashing stock samsung rom, i have been stuck on emergency calls only,help?

Hi,
After flashing stock s3 rom my sim card is not being detected. i know the sim card works because i tried it on another phone and i have a feeling my efs file has been made corrupt as my imei has been completely changes to 0049xxxx. Also i cannot connect to any wifi network but theyre being found . ive looked everywhere and found no answer. Please help me on how i can fix it.
I'm guessing that you made no efs backup? Do your phone's cellular functions or wi-fi work while running a custom rom? What kind of GS3 do you own (i9300 or i9305?).

You cannot go backwards to 4.1 with out a efs v1 back up. Somewhere in 4.3 samsung updated it to v2.
Without a back up you can only use the latest 4.3 and upwards.

You need to use 4.3 or use a modem that supports efs "V2". The reason CM does not work is because it doesn't touch the modem so its still using the one from 4.1 which was the last one you tried.
Options:
1. Flash and use 4.3.
2. Flash 4.3 then install another rom like CM.
3. Flash a efs "V2" Modem.
Either way I suggest you backup your efs become you corrupt it.

Looks like you didn't read the links i gave you or even looked at the stickies or done a basoc search.
Im not willing to help someone who won't help themselves.
Im here to help and guide not to do it for you.
If you thought otherwise im sorry i gave that impression. If so you need to wait for someone else.
