I recently flashed my Samsung Galaxy S III with ultima rom.
It installed perfectly. However, my sim is not shown. No mobile networks are shown. I am from Pakistan.

READ the faqs and guides before flashing .
Is your IMEI correct of not restore your backed up EFS folder .
No EFS backup as per the instructions then you require a service centre repair .
Read the faqs and guides critical to understand post one and two BEFORE flashing
before sending to service center you can try installing a stock rom from sammobile via odin. this sometimes recovers the imei and network connection. you need to install a stock rom and reset your flash counter anyway if you want to keep your warranty
Make sure to flash a recent rom that uses mg2 or mg4 baseband.

What modem did you install? if you installed XXEMG4 it would have formatted your 'efs'
Check your IMEI by dialing *#06#
for more info check this link
The modem does not format or erase the efs folder. It alters the format so older modems can't use it. That is why if there is no efs backup prior to using mg4 or mg2 modem. It is impossible to revert to older modem

Its actually the rom not the modem and yes, ultima is based on a version of the rom that alters efs.

Not sure what you're asking.
Read general > Sticky roll-up thread > "IMEI / EFS - Know this stuff"
Everything I have read, but if you want to return a Nandroid backup, if you will?
It's nowhere
if your nandroid backup does not use an mg2 or mg4 modem than it will not restore your network. if you want to fix your phone go to sammobile.com choose any rom that uses mg2 or mg4 modem. flash it with odin. if that doesn't work take it to a service center

I haven't found a custom ROM I've liked, so I want to go back to the stock Samsung ROM for my i9300 (UK).
Which should I download and flash to my phone? I9300XXEMG4?
I would, it's best BTU firmware to date

I had to Google "BTU". I believe it's a UK firmware variant.
The other UK firmware variants seem to be: "BTC, CPW, H3G, O2I, O2U, ORA, OXA*, TMU, TSC, VIR, VOD, XEU"
What's the difference between them all, and is BTU the one I want?
BTU is unbranded like from carphone warehouse as opposed to branded that you get direct from the carrier
please try to remember; questions go in the q&a section. General isn't for questions

I don't know what that means.
If you dont know what that means, you definitely shouldn't be flashing things!
I'm not sure how basic I need to be so i'll be as basic as I can.
The s3 has an efs partition. This is a partition on your internal memory that stores your imei number among other things
The imei number is mucho important. Without a working imei number, your phone cannot operate on a mobile network. In otherwords, your phone is nothing more than a miniature wifi tablet.
Every official rom comes with a baseband. This is also known as modem or radio. This is software and its responsible for connecting your phone's telephony Services via the radio hardware to the network.
Many rooted users change their baseband in the hope that they get better signal / battery life
Now here is the problem. The latest official 4.1.2 changes the format of the efs. The mg4 baseband "updates" efs. The baseband works fine and can read the imei and the phone can continue to operate on the network. However this new efs format is not backwards compatible. This means any older baseband (packaged with any rom other than mg4) cannot read imei, meaning you cannot connect to the network. At the moment, only the mg4 baseband can read the updates efs so once you flash this rom (and baseband) it is not possible to use any other baseband. If you flash any rom older than mg4, it will only connect if you then put the mg4 baseband back on.... unless you backed up efs before flashing mg4... in otherwords, once flashed mg4, unless you backed up efs, you can never go backwards with the baseband. Or rom....

"JUST... DONT!"
Or make sure to read a guide about flashing roms before you flash any rom. Especially about backing up your efs folder. A lot of the custom roms have options for doing that or do that automatically so chances are you may already have an efs backup, but better not risk it.
Well he could flash that rom but he has to back up his old efs first for getting safe.
But I do not think he is able to do that due to he is unknowing.

Dude learn reading.
Flashing the BTU EMG4 Firmware will change your efs for ever, so if there is any bug or part in this firmware you do not like, the way for backflash will be complicated.
The old modems are not able to run with the new efs, so U have to flash the new modem on the older firmware.
Or you flash back your original efs back.
But this could be very dangerous because people are scared to do that.

Hey Guys,
So I had my usual SIM card working as usual on G4 stock 4.1.2 firmware. I later on flashed CM10.2 20130814 Nightly build after which my phone was stuck on Emergency Calls only. I flashed three different stock 4.1.2 official firmwares after that but nothing seemed to fix it. They recognised my SIM and carrier though they weren't able to make calls and whenever I tried to it gave me the error message "Not registered on Network".
It is a fully unlocked i9300. I would really like your guys help on this.
Questions go in the Q&A forum, report your post and ask for it to be moved.
Does your IMEI number in phone match the one under the battery?
Did you make a backup of your efs folder like all the guides recommend?
If your IMEI has changed and you don't have a backup then flashing the latest full stock via odin on your pc sometimes enables the partition to be read again.

Well, This is the Q&A section. Anyways, I didn't make a backup of EFS. I tried flashing stock as mentioned in the OP but it didn't prevail so what should be the next line of action? xD
Hah! Sorry, my browser took me back to q&a from general.
Does the IMEI match?
If not then you need a repair.
I am currently back to flashing another stock firmware so didn't check. If it doesn't match then what sort of repair would it need?

Problem: /efs partition format changed
The latest 4.1.2 UK (XXEMG4) and India (XXEMG5) ROM releases (Which come with MG4 and MG2 basebands respectively), actually change the format of efs.
If you have flashed a, XXEMG4/5 ROM at any point, you are now in a situation whereby only an MG4/2 baseband can read the IMEI in /efs. The new efs format is not backwards compatible with older basebands. Probably, all new basebands will be compatible so in time this issue should diminish I expect.
If you have ever flashed XXEMG4/5 ROM, to keep your IMEI working, you must:
Stay with the basebands MG4/2. You may flash other ROMs but must return to the MG4/2 baseband.
Restore your efs backup (taken before XXEMG4/5 ROM install) to use older basebands.
Please note, it is flashing the ROM that alters efs format, not the basebands themselves. You can flash the MG4 or 2 baseband safely on their own and return to an older baseband without issue.
You can download an MG2/4 baseband package HERE
Aroma installer, choose between MG2 and MG4 basebands
Basebands alone do not alter efs format
Backs up EFS in an uncompressed format (Use Root Explorer to restore)
Does NOT include RIL, works on AOSP and Sammy

NO it didn't work as i installed the latest firmware through odin, and then get OTA as well but it didnt solve the issue, then i installed the MK6 BTU firmware but it didnt work as well.
tired of installing the ROM's and Patches but non of them worked, is there any posibility to get it in working condition or should i use it as IPOD???
Take it to a repair centre and pay them to recode it, make sure it works on 4.3 firmware before you pay them.
Patches are a work around for modified efs problems, a corrupt or wiped efs can only be solved by professional repair.
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.

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

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
Hi guys , so i was having some problems with calls on my gs3 , (i was sending sms and atuff normally, but from yesterday till today i could make calls in the morning, i tried my moms phone and the carrier signas and status seems ok. so i tough it was a modem problem, i flashed "I9300UBEMH2_I9300UBEMH1_I9300UWHEMH1_HOME.tar.md5" from panama and the signal was OK . so i tried to reflash another modem and i got the "no sim card" error. tried a bunch of modems and none of them worked.
So now im flashing the stock one, but as far as i know it wont read my imei because of the panama was MG4 or MH1 it changed the efs format. But i will flash a mg4 modem with the stuck UBELL1 from movistar southamerica and see if it works .
My problem here is , can i flash an mg4 rom make a back up of the efs with ktools and restore the efs backup on a previous not mg4 rom? and it will read my emai ? (this is happening because i didn't made a back up of my original efs)
Also i was wondering, what will happen when i want to install a 4.2.2 again in the future? or a 4.3? i won't be able to do it since i need to use a mg4 modem to have signal? or can i back up a working efs with a mg4 rom and restore the efs back up on a stock not mg4?
#BTW my sg3 is still attached to movistar (is not unlocked)

This question doesn't make sense.

This is already answered in the thread you said you read.
today i had some idea. But not im not sure about it . So here it is. I am wondering if its completely necesary to use mg4 modems forever on my device to get my imei readen. So is there any kind of method to take the v2 imei readen only for mg4 modems . and make it readable for another basebands modems? like ubell1 ? . i tried installing a 4.2.2 rom, then flashing the mg4 modem. once the imei got readen i made a efs backup with HCk tool , then i change rom and restore the mg4 efs backup . But i got nothing . the imei is not being read.
do you know if what im trying to do is possible? or maybe (as i said before) i will have to forever use mg4 modems on my device? .
with mg4 modems im not having problems is just that , it's a pain in the ass being changing of basebands everytime i want to flash a new rom.
You can only use mg2, mg4 or mh1. Basically any modem released since July. Stop living in the past

Or best stop using Rom that force baseband install.
Hi,
I've encountered a problem today. By mistake i have restarted my phone after the wipe, and soft bricked my phone. Then I tried to flash to stock with odin and after a few tries managed to do it But the problem is, after the flash i've got a "selected network unavailable" notification. Tried many things, different stock firmwares, reinstalled many times, but to no luck. After that i've installed aospa and tried to restore my efs backup, but that didn't help either. My imei is intact and in download mode my model is shown too.. What can I try doing to make it work? I can provide any information you ask.. My model is I9300 International. Baseband version in "about phone" tab is: I9300XXEMG4, the stock rom i've installed is as shown in *#1234#: PDA: I9300XXEMG4 CSC: I9300OXXEMG3 MODEM: I9300XXEMG4
Go read the sticky thread on efs in general forum.
If your efs backup was made when your firmware was older than EMG4 then you need to downgrade to the old firmware before you restore it, as efs format changed at EMG4.
Both the imei and serial numbers are required to obtain network.

I have both imei and serial correct, but how do I check which baseband I made the efs backup on? Because I don't remember..
Your serial and imei is ok.
So I think you should flash a patched modem matches with your firmware

You have just saved my life. Indeed flashing patched modem matching my firmware (UGNA8) after flashing Boeffla-Kernel on stock helped regain my network Connection. May it be a remainder of how easily you can mess up your phone
So officially, problem solved.
