Edit fixed:
After 3 days of testing many methods here is steps that working:
1- copy your efs folder files to sdcard
2- after flash stock 4.1.2 root and adb try to format your efs using efs professional if no error go to last step but if you get (cant mount efs error) and phone doesn't boot go to next step
3-download this file Here and flash with odin this will fix can't mount efs and phone will boot normaly but no network
4- using xplore file manger and set access to root and mount and copy replace efs folder files with your original efs folder in step 1
After this network will work for stock and aosp roms
Please use this only if you getting unknown baseband on aosp roms

I'm currently on omega 43.3 based on xxemc3 with modem DDDLJ1. Planning to move to a sammy based 4.3 rom. Are the following steps ok? Or do I need to add more
1. Backup up data + EFS
2. wipe internal sd
3. boot into cwm
4. install.
A little confused about the modem. Which one should I install ?
Also once I've moved on to 4.3 in case I need to come back to 4.1.2 what are the steps I need to follow?

Nandroid backup + EFS backup + titanium backup + whatever you back up your sms with if applicable
Wipe data / factory reset from recovery
Flash ROM
Use whatever modem you want, it's not relevant.

the modem being compatible with efs v1/v2 will not cause any issues?

Well yes, that's a given. The modem that comes with the rom will work, or reflash the modem you have now. Obviously without an EFS v1 backup, you cannot use an EFS v1 modem. This hasn't changed. But why anyone would need an EFS v1 modem nowadays is beyond me.

Reason why I asked about the efs v1 modems was that I still haven't moved on to the newer modem versions. Have'nt updated since omega v43.3. Guess it's time to change

Well hopefully, you should be able to restore EFS v1 backup after flash and use an older modem. But before flashign latest rom, you could try and flash just one of the latest modems and see how they work for you.
But while flashing the new ROM, you'll get a new modem so you don't need to bother you with a EFS backup. The backup is only here in case of troubles.

Read the faqs and guides .
EFS Pro and other methods .
i read it 100 times, tried with EFS pro but nothing happend :/ ....can i flash efs.tar via odin???
No, try philz recovery instead. Your phone may have been on such on old firmware for a reason, usually a botched efs repair.

ok tnx, now i flashed ultima rom with mg4 modem, now iget out from factory mod with terminal emulator...how i can restore efs.tar with philz reovery???? where is the option to restore in philz?? i have latest philz??
i put efs_Backup in sdcard1/clockwordmod/backup and when i start to restore efs there is a message "nothing to restore in /storage/sdcard1/clockwordmod/backup/.efs_backup/
Try manually extracting the .tar file on your pc. Copy all the files to the efs folder aims file manager, set permissions then reboot.
im on good way, all what i need to do is restoring efs, but i cant, i tried with coping files and seting perrmision but nothing hapend :/ can you help me trought teamviewer??
You must restore the full package. After this try a hard Reset.
You must delete the old files (not more than need)
i restored efs but nothing happend, downgrade to 4.0.4 offical and restore efs folder again nothing, i send it to repair service and wait for it now
Phone: [Samsung i9300 international ]
Hello XDA. I was trying to restore the EFS in this phone with the GalaxySim unlock App right after flashing the Slimkat ROM which gave me a no signal problem. The IMEI appeared as unknown and baseband too so i proceded to trying to restore the EFS backup i had in my pc.
I followed the procedure by doing tap in restore EFS in the app , chose the EFS folder option and then restarted. After that I can only see the Samsung logo and doesn't boot. Since the beginning i got this used phone I could never load the custom recovery (TWRP) from the button combo, it always went straight to Odin telling me to press vol up to go to download mode.
The only way around to get to TWRP was by using Goomanager and using the reboot to recovery mode option. That's how i managed to install the Slimkat ROM. After that I always get the red exclamation sign while booting but still everything was fine except for the phone signal not working at all.
What can i do now by using only download mode? What are my alternatives?
I hope you can help me.
Thank you.
EDIT 1:
I managed to boot to TWRP with adb shell by "adb reboot recovery"
and when i try to flash a custom ROM or the backup before the Slimkat it shows this error:
"E: failed to mount /efs ".
EDIT 2:
So now that it's a EFS failed to mount case , i'm following this:
http://forum.xda-developers.com/showpost.php?p=37533150&postcount=12
but i dont know what version of busybox to download. Which binary should i get?
I recommend that you stop flashing anything else on the phone until you confirm that the model # is gt-i9300 in download mode.
After confirming the model #, download the latest stock ROM from sammobile.com and flash it in Odin. Boot the stock ROM and see if the imei is properly displayed.

This is on the back under the battery:
Model: GT-I9300
FCC ID: A3LGTI9300A
SSN: I9300GSMH
Also when I try to charge the phone by the wall socket the battery animation seems to be just frozen. Which stock ROM should I download? Does it matter the country? I don't know from which country might be this phone.
Have you had the from new or did you get it used?
If you got it used, I wouldn't trust the label. You should confirm the model number in download mode.

It's correct the model, it's a used phone and:
Custom binary download: yes (11 counts)
Current binary: custom
System status: custom
Flash the latest stock ROM from sammobile.com with Odin. This will remove root and don't forget to perform a factory reset before booting the stock ROM for the first time.

From any country or at least close to where i got it from? 4.3 android i guess?
I have never found the country to make difference so pick a country closer to you with the language you need.

Thank you for your help. It worked and now its running a stock firmware but I cant get wifi working on it, it keeps saying connecting-saved-secured and reconnects. The phone signal its fine and can make calls without problem but now i flashed TWRP and It doesn't let me get into it nor with the button combo or the Goomanager. I want to backup this EFS asap and try another custom ROM.
You can't get into recovery mode at all?

I can at the moment, it was just USB debugging that was off. Again i used the adb command to reboot into recovery. Now , what TWRP version should i get to backup the EFS in .bin or any other format that i can flash with Odin. Can you recommend me a ROM that doesn't mess with the EFS?
I haven't had an s3 for over 2 years but I recommend flashing the latest tar version TWRP in Odin.
Alright, I did a backup of the EFS in .img and a modem backup in .bin with this:
http://forum.xda-developers.com/galaxy-s3/general/tool-backup-restore-efs-imei-sgsiii-t1901098
then i proceeded to flash a custom ROM and wifi works but now the phone signal goes intermmitent, the icon with the bars goes full and empty constantly, it identifies my provider tho. Airplane mode triggers on/off automatically. Should I restore the EFS from stock ?
Edit: flashed the modem.bin from stock. Airplane mode still intermmitent.
Don't touch the EFS if the phone is showing the correct imei. You flashed the latest stock ROM? Does this signal problem happen on stock too?

In stock there was no problem at all with the signal. The wifi thing was my router actually, some authentication problem related with the use of the password.
Edit: flashed another modem that was tested by other user with the same ROM and phone went completely unstable and couldn't identify the network. Went back to my back up of modem, still airplane mode goes on/off.
I suggest flashing the latest stock ROM and then test. I only used stock modems and bootloaders on all of my Samsung phones.
If the phone doesn't work properly on stock, custom ROMs may exacerbate the problem.
After a long day of testing, only the latest stock ROM works properly while every other custom ROM has the same problem with the phone signal, CM11, slimkat... What's happening?
Edit: flashed CM13.. still the same.
Sounds like you are limited to stock or stock-based custom ROMs.
Hi.
Yesterday i flashed on my phone ressurection remix on nougat. It booted up properly and everything was ok. So i decided to flash Boeffla kernel as i think its best. Phone was starting more than hour and then truned off. I booted it up in recovery mode just to reinstall system without the kernel and then first problem appeared. It couldn't mount E:/data because i had this problem once i knowed what to do (format data and data/storage) after this i flashed cm 13 to be sure that everything is working. There 2nd problem appeared, it had 0049 imei. I thought that i'll just flash the backup that i had in my phone but i forgot that it was deleted as i formated storage. I looked in my computer for efs backup and found a backup made by this
PHP:
https://forum.xda-developers.com/galaxy-s3/general/tool-backup-restore-efs-imei-sgsiii-t1901098
and restored it. After that i rebooted phone and i gave me "unknown" imei and baseband. What can i do? I also have efs pro backup but the app don't see it ;-;
Thanks for any help it will be appreciated
ps. If it's corrupted backup i can pay for writing the proper one, but i want to make sure that the backup i broken
you can open efs.img with 7zip and copy in twrp that files nv_data.bin and nv_data.bin.md5 to efs partition?
stock rom working ?
imo erase efs and radio partition and reflash in twrp, maybe that custom roms dont working for you (depends on version galaxy s3)
Before flashing anything else to phone, I also recommend flashing the latest stock ROM from sammobile.com with Odin to see if that restores the imei.
It cannot be opened as an archive. Customs are working properly because before this error with /data partition i used this rom and everything worked properly, then i decided to flash the boeffla kernel which i think caused whole problem. After flashing other modems it stays unknown
EDIT: I tried also zuluman patch modem but it didn't work. I don't have chance to go to stock by odin because my pc is not recognising it in download mode(probably broken usb port in phone)
its should working (opening with 7zip), do you have recovery twrp ? (easer way that "play" with updater-script)
stock rom you can flash via terminal in twrp
Did you flash the correct Boeffla kernel?. Are you sure you flashed the correct Boeffla kernel?.

Latest for lineage os which is a variation of cm and ressurection remix is some kind based on it if im not wrong ofc
I presume you wiped dalvik and reinstalled resurrection remix so the only way to go is back to stock. Any problems after that, at least you'll have a solid base to work from.

Stock + zulumans patch worked, backup wasn't corrupted. Thanks all of you guys that tried to help. I appreciate that
Hi everyone,i am asking for your help i am noob at this. So i wanted to install a custom rom on my s9+ (Pixle Expirience),after using the rom i installed a random android pie kernel,then the rom woudnt boot.So i installed a normal custom rom that i knew it worked.I flash that but i didint have mobile data and i coudnt see my IMEI and my flight mode was plain blue instead of gray(but my wifi worked like everything elese).Then i installed stock firmware via odin,still nothing.
Then i panic and found some software which with u can insert your IMEI,but i have accidentally wiped my efs.So now when i install firmware it is stuck at samsung logo,and in TWRP it says failed to mount /efs Invalid argument.So i ask u if u can guide me on what to do and how to get efs file.Your help is appreciated.Thank you
