Please read general > Sticky roll-up thread / IMEI / EFS - Know this stuff.
Every ROM since July changes EFS. Why would only July ROMs do the upgrade then not August?

i have just 2 or 3 simple questions. especific quesitons that i cannot find the answer on your post. or maybe the answer is on the next 11 pages? you mention on your post only MG4 roms or newer. don't say anything about Mh2 . so the questions is kinda easy, would i am able to have signal and imea read on a 4.1.2 if i flash a mg4 modem after install ? . and same thing happen to 4.2.2 or 4.3 will i have to always flash a custom modem to have my imea readden?

I've got this fragment you wrote.
"If you have ever flashed XXEMG* (or newer) ROM, to keep your IMEI working, you must:
Stay with the EFS v2 basebands (MG* or newer). You may flash other ROMs but must return to the MG* (or newer) baseband
Restore your EFS backup (taken before XXEMG* or newer ROM install) to use older (EFS v1) basebands. EFS backup must be an EFSv1 backup to use an EFS v1 baseband
If the above don't work, consider sending for repair... "
SO i will have to back up and restore the mg4 mh2 efs every time i want to change rom for a older one.. do you know if 4.3 (as it will be obviosly new) will have a mg4 or mh2 mh1 modem? . im kinda having problems on my calls . internet and messanging are just fine . but some times when i want to call the automatic operator says " the call could not be proccesed" but dunno if this is a signal problem or it is just me.
does k tools back up v2 efs?

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.

MG4 is perfectly safe, it is a BTU firmware intended for the UK, it works extremely well and it is the users of this forum that don't know what they are doing that make it unsafe... It's as simple as 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 searched and think I know what I'm doing, but I wonder if some kind soul could confirm what I think, before I eff my phone up?
I'm currently running a 4.2.2 Samsung ROM (Archidroid) but I'm not happy with the lag. I want to go back to a 4.1.2 ROM.
Am I correct in thinking that I can just flash the new ROM and then restore my EFS backup, and I won't have a problem with losing my IMEI/phone going into factory mode, etc? My EFS backup was done when I was on a 4.1 ROM. Or do I need to restore EFS before flashing the new ROM?
Thanking you!

just back up efs every time. be sure> flashing firmwares based on MG, changes efs format to a new one. after that if you wanna flash a firmware based on previous releases(to XXEMG4), you will be facing network problems like no data connection, no calls, no text messages etc., so once you flash a firmware i.e released after MG4, be sure the next custom rom/ stock f/w you flash is newer to it. good luck
Can I not flash an older firmware safely by restoring my EFS? Or is it risky?

Yeah thanks, I've read that more than once:
If you have ever flashed XXEMG* (or newer) ROM, to keep your IMEI working, you must:
1. Stay with the EFS v2 basebands (MG* or newer). You may flash other ROMs but must return to the MG* (or newer) baseband
2. Restore your EFS backup (taken before XXEMG* or newer ROM install) to use older (EFS v1) basebands. EFS backup must be an EFSv1 backup to use an EFS v1 baseband
3. If the above don't work, consider sending for repair...
This is the part I am worried about.

that's what exactly i was trying to tell you. XXEMG4 f/w is some what problematic but the f/w-s released after that are good enough. once you flash any of these f/w-s, back up your efs for sure.
:good:
Yes, but I want to go back to a ROM with an earlier baseband than EMG4, so I can use a custom kernel. The performance on later ROMs with the standard kernel (which is all you can use at the moment) is not satisfactory.
So my question is, in order to go back to a ROM based on firmware earlier than EMG4, can it be done SAFELY? If so, do I need to restore my EFS backup before I flash the ROM or afterwards? Or, if it's not safe then what should I do to minimise my chances of messing my phone up?

Try different 4.1.2 stock roms prior to 'MG' series. Make a clean installation.
As you were on 4.2.2, you were probably not on efs v2. Take backup of efs.
Sent Via I9300, Stock XXUFME7, 4.2.2.
how to restore to 4.1.2??
I have installed 4.4.2 AOKP firmware on S3 GT I9300. I have backup of previous version 4.1.2 through CWM backup. Now i am trying to restore 4.1.2 backup through CWM but unable to do. I have tried a lot but can't restore previous.
Plz anybody help me resolving this issue. how to restore my previous version 4.1.2 from 4.2.2 with the existing backup?
Thankss if anybody help me out.
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 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.

I hope you have an efs backup. if not follow the steps in the linked thread.
btw which 4.1.2 did you flash. when you flash 4.3 rom efs will change to v2 so you need a rom with efs v2 baseband (everything newer than xeemg4)

yeah I know but which one (the build number) something like XXELLA or XXEMG4...? you can see it in settings menu
in fact if you have flashed a firmware older than XXEMG4 then also its baseband is flashed, and these old basebands are not compatible with efs v2 which has been flashed through your sammy 4.3 update.
This could PROBABLY have caused your imei problem and you would only have to flash a baseband newer than XXEMG4 to PROBABLY solve it. or your efs is corrupt than you should follow the steps in the stickies
