Hi! Yesterday I got the same problem, after flashing some random 4.2.2 rom. Anyways, I tried flashing a lot of original firmworks via odin, and after that flashing basebands provided in OP's post. Nothing worked. So I flashed ISC rom and after that I flashed omega rom. Still nothing. Then I flashed basebands again, and it worked. I don't really get it why. Could someone explain? And, can I go to CM roms? Also, I can make/recieve calls, but smses are not working at all. Thanks
[Galaxy S III General] danarama:
It's not really possible to explain why. If you have EFS v2, then all you should need is an EFS v2 Baseband. This should work on any ROM
[Galaxy S III General] kzkan:
Yes I did like mentioned above and result is perfect. Thanks a lot otherwise ı would sent my s3 to garbage
[Galaxy S III General] Kyle07:
I wanted to switch to ME7 baseband based on some comments on the Temasek thread with regard to improved signal. Before I flashed CM10.2 I ran Omega MG6 with MG4 baseband.

So, I restored EFS (backup made

before

flashing MG6 ROM), using ktool, and then booted to recovery to flash ME7 baseband. After reboot, no signal.

I have several EFS backups from before the MG4 EFS conversion and none of the backups left me with signal after boot.

The only way to get signal back was to reflash MG4 modem and then restore EFS backup made post MG4 flash.

Why are my backups for "EFS v1" not working? Any idea?

Any assistance would be greatly appreciated!

Did you completely delete efs contents before restoring? Sometimes you have to do so. And other times, the backups just don't work :(
[Galaxy S III General] Kyle07:
Hmmm. I haven't tried that no. I'll give that a go when I'm feeling brave again.

I'm aware of that. I restored the applicable backup in each case. Or am I confused?

GOOD NEWS

finnaly I got my sgs3 - i9300 working and working like a charm...

First of all

- what was the issue?

# I was on " XperianZe-0.9.9_AROMA_JKay_Elegant6-EMC3 "

I installed " I9300_Omega_v47_XXEMG6 "

I was not happy with battery, while installing the omega the installer from aroma took my efs backup.

Then I tried to revert to xperian, I was screwed

IMEI WAS GONE - GENERIC IMEI

I used a tool called k tool ( it's free on market )

I formated efs partition and used the dump to restore.....

I am in hurry so pm me for detailed help....

But let Me tell you

- rootsu suggested you take the device to service center

- and service center guys died trying, 1st time I took phone to s.c ,the phone was in boot loop they failed. 2nd time the phone was on, they failed.

- even octopus box failed

- jtag failed

- riff box failed.

Even my efs partition was so corrupted It was not being mounted... I did not even had. Info backup....

Brother it's an achievement for me....

Update to post 1:

You can download an EFS v2 baseband (CWM) flashable package

Includes MH1
[Galaxy S III General] Egozy:
Flashed MH1 just now, twice, and when I go into "About phone", I still see Baseband Version: I9300XXEMG4
[Galaxy S III General] Egozy:
Seems like the EFSv2 flashable (the Aroma thingy) doesn't flash anything. Tried the 3 options, two times each one, and I'm still on the same MG4 I had before.
[Galaxy S III General] danarama:
Think I uploaded a broken one by mistake. Can tell instantly if broken as the Install is instant and no backup done.

Thanks for helping

1) I had Omega v43 4.1.2 working fine for a long time, then flashed v46 4.2.2, problems started then

2) Yes I have tried wiping everything, and factory reset

3) I rooted with Samsung GS3 ToolKit, installed Root Explorer and checked EFS folder to be empty.

If I copy contents of old EFS folder to /efs I get 0049*** instead of null / null. If I reboot, the EFS is empty again and I get null/null

I presume that this old rom can boot without anything inside efs folder. Any newer ROM flashed, does not boot
[Galaxy S III General] Crowds:
Just a thought/question

Couldn't we just bk place efs folder i.e. on extsdcard or anywhere else and just copy/paste to \system and give same permissions?

it didnt work later i induvidually deleted efs folder contents that worked ; finally copied the backed up contents from tar.gz and copied to EFS folder and rebooted and it worked . IMEI restored + network no service issue solved + i'm not crying anymore :D thanks . gathered quite alot of info from several threads :)

[Galaxy S III General] kangerX:
if you've been flashing a lot there s chance that some ROMs might ve had the auto efs backup script. just look for efs.tar.gz backup in sdcard. I got lucky because a ROM I flashed on jul16 saved my efs. if not there's a thread thread '9 steps to restore IMEI' last resort in case you didn't back up... might work.
[Galaxy S III General] jorgefcbastos:
Okay, this is my problem.

One week ago, I was using Cyanogenmod 10,1 when something in a normal update went wrong. Then I could realize IMEI was gone and couldn't detect network.

After that, I could restore IMEI because I had the original efs folder. However, I still hadn't network and was in factory mode so I had to search for a solution.

First I flashed the MG4 ROM and then I could exit factory mode following this guide step by step. In this moment I still can't make calls and the IMEI which I had before is gone (serial number either).

Having some difficulties to find the correct information. Is it possible to have network back? I remember that I have the original efs folder backed up. Would appreciate your help. There's a lot of posts and threads and I'm not the best in English, so I'm having some difficulties. Thank you.
[Galaxy S III General] danarama:
So what rom and modem are you on now?
[Galaxy S III General] kangerX:
Well delete every content from efs folder of phone (don't try to delete whole efs , because it won't. You all need to delete contents separately within efs) after that simply copy backed up efs folder contents to phone's efs folder and reboot !

PS: I used root explorer (duh!)

Added the above, including MG2/4 baseband aroma zip (sans RIL) and EFS backup

Just did what chris_marsh said and something weird happened: I wasn't in factory mode befone cleaning the efs folder (file by file) and now I'm in the factory mode again, but my IMEI and serial number is okay once more. So, I can't understand what is happening. What to do first, and what's next? A help would be precious.
[Galaxy S III General] danarama:
Next, use the commands in post 1 to exit factory mode.
[Galaxy S III General] jorgefcbastos:
Did it. Now I'm out of factory mode and have IMEI.

Next?

Copied EFS folder contents to empty EFS folder

Installed GSII repair. steps 2,3 reboot

EFS Empty

Restored from GSII_repair, set permissions as per your post.

Restarted

EFS folder empty again

UPDATE* I ticked all the boxes for permissions of the actual EFS folder then used HCK tool to format EFS. Restarted and now I have contents in the EFS folder. Also, WIFI is working now

Baseband now says - I9300XXLH1

so good news... but... IMEI still 0049***

That's a generic imei. That's not yours. You should now try gs2 repair from there.

No. It never corrupts it. It alters it. But if you're flashing stock roms, that's fine. Problem is for people who want to use older basebands

2) Yes the phone is booted and running, everything works apart from IMEI problem. Wifi is okay, the is network. But IMEI won't register on network so I can't make or receive calls

You need to either

1) restore EFS every time

2) flash one of the modems from post 1 every time

I will own a sg3 in a couple of day and I have a few questions.

Then, if I flash an older rom (stock or not) I will get "no network". My question is, if I flash back the newest stock rom won't be my problem solved? As the newest rom should be able to read the efs.

Permissions. They must be correct. You can't get tge correct permissions simply by pasting your backup with es. You'd have to use adb like post 1. Tools do this all for you.

Philz recovery is the best tool for me but I too use folder dump.

[Galaxy S III General] danarama:
Every file on your phone has a permission set on it.

Read yes / no

Write yes / no

Execute yes / no

By who?

Owner yes / no

Group yes / no

Other yes / no

With the incorrect permissions set on files, things don't work properly.

If you backup the way you suggest, all these individual permissions are lost and you'll need to set them manually to make EFS work correctly.

Make sense?
