NO one found this folder on the galaxy mini....the phone can turn on or not?? if yes u can unbrick...

efs folders are unique you have just removed your imei now if you don't have your own backup nothing can be done
now your mobile is a mp4 player if anyone uploads his efs file his mobile will also be a mp4player

Just because you're a Recognized Contributor, that doesn't mean you can bull****.
That is not true! Admit it, you don't know how pull the /efs ot from your phone
Like you said, /efs folder contains alot of things that are unique for each phone (WiFi MAC adress, IMEI, product code and what not), so we can't just give someone our /efs. Even if we could, the way of pulling those files from the phone are not known to me.
Wish we knew a way to backup it, when something like this happens - you just put the backup and away you go

just because am an rc that doesn't mean am bullying
nothing difficult in backing up efs file just go to /efs and copy those files to your sdcard and they will be backed up
but efs is visible only in operator specific models in normal phones imei is hardcodded in the mobile
mine galaxy s is of at&t and I can see the efs folder, prior of flashing roms on it I did a backup of that folder
and sometimes it got deleted then I just need to copy them back
can't see on original galaxy s of my friend
the thing is one imei cannot be used in two mobile there can be many conflicts and some also related to laws
only one sim can be used at a time on a single imei
that's why I said mp4player but you can still try to share your efs files if it works then just keep it else delete it

op if you have your operator specific firmware and it contains an efs.rfs file then you may have the possibility of getting back your imei
just try it, may work

Things on Galaxy S and on our mini are a little bit different for that /efs matter, because nvdata.bin is in devblock5 or something like that, an on Galaxy S it's in a different place. Strange, but it is that way, i tried all the Galaxy S tutorials to make a backup and none of them worked.
And yeah, you cant just copy the folder since that will **** up th permissions and then the files are almost useless.
Yeah, he has a great MP4 now, unfortunately :/
I know imei is unique, thats why i said ''if we could give our efs''

just copying the efs files works great for me
I never changed permission of efs files
and had done it three times by just copying

If you distroy your IMEI becouse of bml/efs you can repair it with JTAG. Write full dump then repair its IMEI (to be the one from you stiker). Generaly this is a Service job becouse you dont't have the necessary tools.

i don't have this /efs folder, but i still can browse internet, call my friends, do a SMS, play music. Just like a normal phone do.

if you cant see that doesn't mean you don't have efs
it is just that you cannot see it like you cannot see bootloader, kernel etc.

I'll highly appreciate your help ppl!!

Where did you copy your Backup
Sent from my GT-I9100 using Tapatalk 2

I made a backup via cwm..im trying to restore "data" and "system" via advanced restore and see wether it works..currently doing that

OK let me know then!
If it not works, try the app nitrality from market, you can try to restore your efs backup with the app
Sent from my GT-I9100 using Tapatalk 2

didnt work.
So now I am fully restoring it via CWM, before i was rebooting into CWM mode, and then advance restoring.

Ok I'm gonna also try that app and let you know!
Btw thank you so much for your help man!! Im so bloody depressed! :-(
The damage is reversible right? I mean im not a gonner am I? I'll keep you updated!

Since you made an backup of your efs folder its always possible to restore so no reason for getting depressed mate!
Sent from my GT-I9100 using Tapatalk 2

I restored it fully, but after the phone rebooted, it just got stuck at the boot screen..i took out the battery after 5 mins as it was still stuck at the boot screen.
What do you suggest now? I'll try that app you suggested once I get my firmware working!
Retiring for bed, will follow up on your advice when i wake up..

Go into the recovery and make a factory reset, if the Akku trick won't work

Did you make sure you flashed with a .pit file as well,? You must do this down grading as the file partitions are different from ics

Ok I tried to go into recovery mode, but the phone would just boot again, from the very first boot screen (where samsung is displayed at the bottom)..so should i flash again with the .pit thingy?

ok guyz nitrality didnt work..flashed it with gingerbread with .pit again..no imei number

Do you have a back up of your efs folder?

Yes i have the efs backup on my pc and ds car. I tried copying the efs to system root dir, but no luck.

the nv_data.bin file is 2MB in the backup folder on my sd card, but as soon as I copy the whole efs folder to root dir, this nv_data.bin file is 0bytes size..

One question, when u copied your Backup into the root directory
Did you made a reboot then?

No I did not reboot after copying it to the root directory. Let me try and I'll let you know

I copied nfs to root again, but the nv_data.bin file is reduced from 2mb to 0bytes as soon as its copied...and reobooted but still no luck...

What app do you use for copy your Backup and another question, in what folder exactly do you copy it

he restores IMEI.. may be he can help you.

He can do this when you can show and prove that you have and own the original imei number. He can't "invent" one.
So you should check this first.

No, because using hardware equipment is part of the repair process.
Until now I do not know a "software" restore mechanism (if you do not have a working backup of your old efs).
And I read and checked a lot of threads about this because I have a device where the IMEI is written in letters inside the device but not anymore in the efs - I have the so-called developer IMEI.

You should fist explore your note with root explorer. Depending on the rom you're using, you may have a backup of your efs partition (some rom do it automaticaly).
Watch your SD card if ther is a file called "efs.img"
You can also look inside the efs partition if there are files called .nv_data.bak and another one called .nv_data.bak.md5
If yes, you can fix it yourself.

Pssst, do not tell anybody. But I guess that developer door is closed now, since November nothing (I check for OTA updates every day - I can do the install XXLSA/restore GB backup process while deep sleeping now).

i have found in the efs folder from internal memory the files! what now?
take a look!

Rename nv_data.bin to nv_data.bak
Rename nv_data.bin.md5 to nv_data.bin.md5.bak
Then:
Rename .nv_data.bak to nv_data.bin (remove the point at the begining)
Rename .nv_data.bak.md5 to nv_data.bin.md5 (remove the point as well)
Restart your phone and let us know.

ok ,i will copy those files from my backup efs folder in the interlan folder efs..rename it and i will process something in terminal?! or i will just reboot the phone?

well you are stubborn, stubborness is annoying but can lead to great inventions and progress. However to save you time shiuld you fail, you will not without an efs backup be able to fix this. Imei gone is gone, no efs backup then need Samsung or cvxcvx.

All can be done with root explorer. Just long press the file to rename and then chose "rename" and edit the name.
Files don't have to be moved, everithing needed is inside the efs folder.
After renaming those files, just reboot the phone.

so i delete the efs folder from internal memory and i did what you said to me and nothing take a look at the pictures

S3 MINI i8190 IMEI NULL after cyanogenmod update

Hi guys,
Yesterday I updated my cyanogenmod 11 with newest version doing a wipe cache first. After rebooting my phone seems to have an issue: the IMEI is null and I can't call or receive calls.
So I decided to flash the stock rom with odin, I thought that this could help, but nothing to do, the IMEI is still null and I can't use the phone
The first time I installed cyanogen I made a backup (using TWRP function), looking for that backup files, I discovered a file called efs.ext4.win, but if I try to open it with an unrar program, I see these files inside:
\.files
\bluetooth
\FactoryApp
\imei
\RFHAL
\RFHAL.DEF
\wifi
GUARDFIL
gyro_cal_data
pre_recovery.log
I don't see any "nv_data.bin" file or something like that. Is that normal?
Anyway, I think that EFS folder is corrupt or missing, i don't know. Is there a way to solve this issue? Thank you.

Thanks for replying.
I tried to restore EFS folder using TWRP and my backup, but nothing changed, I still don't have Imei and baseband.
Do you think that flashing a PIT file could help me?
Thank you so much.
