hello, i have a question, in galaxy is recomended that make a bkack up of efs folder, for IMEI, is the same in WT19i?, and if it is, where is the folder with IMEI number thz.
Why would one need to backup IMEI?
Doesn't matter what you do with your phone, it won't change. The IMEI is written deep in the system(not in /system or ROM, even deeper). Where exactly, we don't know.
Can't remember, how was that file system called...
IMEI
hello thz, i see Galaxy s2 have a folder called efs where is the imei, and in some cases it cant damage and you lost it, for that reson thery recomended backup it, THZ

Sorry to inform that,IMEI on samsung phones gets messed up very easily.Flash 2/3 custom roms and you'll probably end with a generic IMEI.I had a galaxy SII with generic imei.I tried a lot to recover the imei.But as i didn't have the backup of "EFS" folder,I was unable to restore it.Now using a xperia mini pro.Don't know if phones from sony has these kinds of problem or not...!! Searching....!!

I have a Samsung Galaxy S II with lost IMEI & unknown baseband, ( the source of such a problem usually is the corruptness of the efs folder or missing ), My question is if the efs folder is missing would it be possible to use another backup from another backup of the efs folder from different S2 and edit in the details needed?
You can restore from your backed up EFS folder .
Or search XDA >>> EFS will find a number of posts and some fixes .

Hi mate, I don't have a backup of the folder so can't restore
no, you can not use a efs from another phone as the imei is unique to each phone. you would end up bricking it.
You need to send it in for reflashing with specialized tools which will rebuilds your efs folder.
I have the same problem here.. any idea how to rebuild the efs folder?

Theres also a Dev called Odia that can restore lost EFS/IMEI folders.Costs i think but its worth it if you cant get it done yourself.Send him a PM.

I managed a solution to get your phone back, not perfect but works.

Cant understand why people do not make a backup of the EFS. If they all took the time to read the stickies, they would know how important this is. Learn to walk before you start to run.

That's assuming they indeed read the stickies, of course.
Reading
Read Stickies is important, but sometimes there are procedures that don't work well, or as expected, so problems like this will appear and they must have a solution.
restore with a backup folder!
You may not of personally made a backup but a lot of roms and kernels do it for you automatically, so you may have one or more backups and not even know it.
Check if you have one in /data/.siyah if you have used said kernel.
Check your sdcard for any made by roms they usually make a folder named something like efs_backup
Last I looked in addition to the backup I made 5 minutes after buying the phone I have 20+ made from each rom upgrade.
Hi, I'm new to rooting etc. Is it too late to backup an efs folder after I rooted the phone but have done nothing else?

As long as your EMS folder is intact and IMEI is correct, its not too late. There are a number of apps and programs to backup your imei. Ktool is one of the best and simplest to use. Also try EFS pro.

Mate when people buy a phone, they don't expect that their phone's EFS will get meshed up. In my case I have Galaxy S and my wife has Galaxy S2. She has been using her phone for year and half, no major problem. Last week it suddenly lost the network connection. I tried different SIM but still no good and started searching to resolve the issue and I found how to access IMEI. It was empty. She didn't do anything, no new apps installed. Mobile service provider can't help..

Recover IMEI on the Galaxy S II and Other Samsung Devices in Nine Steps
credits to xda and vaskodagamma
Sometimes bad things happen and you don’t even know it. Flashing modules can wreck your WiFi, kernels can bork your camera and, and flashing some ROMs can mess with your EFS folder—and thus your IMEI—on Samsung devices including the popular Galaxy S II I9100.
XDA Forum Member vaskodogamagmail has posted about a method that may help users restore their IMEI if the all-important EFS folder is modified by accident. In a nut shell, restoring your backed up IMEI involves deleting the corrupted EFS folder, creating a new one, and doing a few file modifications with a root-enabled file explorer. In the words of the developer:
so I researched. searched all the forums and didn’t find anything that could cure my phone’s IMEI and set it to the original IMEI number. so I experimented and after some hours, I fixed my IMEI.
one thing that led me to the conclusion that ” .nv_data ” file is the thing that I need to fix the IMEI is that they share a very look alike name, and they have the same 2MB size.
While the guide was written with the Galaxy S II in mind, the method should work on all Samsung devices with EFS folders. Those looking to restore their IMEI should visit the original thread for additional information and the full method. Just be sure to back up your device, including the contents of your EFS folder, before getting started.
so head over to the thread

fool huh. this is an info, and just read the comments on that page and its not for someone who has fully lost imei.
Lol. it suggest to backup efs. In order to do so we need to mount the efs partition first. Doing so is the most common cause of lost imei in the first place.

OP haven't read older threads from forums
okie.. Now those who hav lost there IMEI must be on Network locked rite?? As of in INDIA we dont hav these network locked phones much.. Only some providers gave some phones but these branded devices are rarely network locked.. So i checked my phone with Root explorer and also in recovery menu no file such named as EFS(encrypted file system) which mainly holds the IMEI.. May be these nw providers afraid that the person might change the IMEi..

EFS(encrypted file system) is for Microsoft.
Android /efs is different from EFS. And our method of storing imei is different from other Samsung devices. So the OP method Won't work.

EFS is not a folder btw its partition which is never mounted to use with some file explorer things as you can see how much loss you can get just by mounting this thing manually

Hello Guys,
I have an 8 month old i9100 that never had a custom rom or even root, but for more than a week los it's baseband information/IMEI and all the rest. The EFS folder was intact, no file missing and I tried all the known restore methods of restoring the IMEI but with no succes.
My question is: can it be a hardware problem? The service said the board need replacement. I have to mention that the phone had some serios drops in it's lifetime, but non of them when this problem occured.
I need some advices...
Thank you!
hardware prblm cause no root,custum roms,or changes,tweaks u made ..but phone had serious drops u say...so the board mus b damaged..do u hav efs bckup,if yes then root an restore using helcats tool..

It's not my phone and I had to use the EFS folder I found. I tried with other nv_data.bin files but no result. is like phone refuses to read the file. No previous EFS backup as the user of the phone has no idea about custom FW and stuff like that... he uses what he buys.
go in efs and delete nv data.bin and nv data.bin md5 an there is a imei folder u can delete and replace with the backdup efs.....but sure u hav the good efs bckup or the phone is fu---ed up

already did everything I could... nothing seems to work. Also, afik if you delete the efs folder, the system creates another one with nv_data.bin inside, ofcourse not a good one. In reality, in this phone if I delete the efs, at reboot it gets recreated but with no nv_data.bin inside...weird
Wow M8! I just posted a question regarding a GS2 i bought from a friend with the exact same problem. If you find something let me know, If i do ill let you know then. But i guess its not because of the drops the phone has taken because the one i bought is intact. But exact same issue here....
Hi everyone! I know i'm not the first one who has this problem but i'm one of them.
I read and tried everything on what i could find about this, but i can't get it fixed! please help!
The situation:
I have a I9100 Galaxy S2, and it works fine, except for the cell phone functionality. It sais "Baseband unknown", has no imei number (also no 0049... imei), and i tried multiple EFS folders (i also have one from a friend who got it from his own Galaxy S2.). But no work.
In fact, i read that if you delete the EFS folder, it should autocreate a new one. It kinda did, but it only generates a bluetooth, upgaddr and wifi folder. Nothing more nothing less.
I flashed another rom, i flashed another phone image with Odin. I tried to erase all kinds of stuff with the clockwordmod recovery. But nothing helps so far.
If i'm correct from my standing, it looks like the baseband is broken itself. Why else wouldn't it even recreate the EFS folder? I'm starting to think that my original EFS folder (which i backed up before replacing it) was fine, but it's not even being read anymore...
Can anyone help me?
Thank you!
bump, still trying. Flashed a new clockworkmod recovery and with adb reformatted the efs partition as listed on xda somewhere. Then rebooted.
The Bluetooth does get a new mac address, so that part is good, but baseband still unknown and imei totally empty.
Also, the phone should regenerate the efs folder itself right? Well it doesn't. That means, it makes a bluetooth and a wifi folder, but that's it. No files or whatever...
Help please!!
m8 y u even delete the efs folder????? anywayz u got a backup so jus copy papte the files of efs...an flash stock rom....if u get un known base band then revert one step back --tht is flash a stock rom then come to present rom--then check///or u can flash cwm modems available suited to tht rom...but make sure u r pure stock--pda,modem,csc.....an yes copy the good efs folder on ext sd card too ,,so tht u can set same permissions like the ones ur copying to phone efs folder(sometimes the permissions change afta reboot)
i'm facing the same problem
Hi guys,
I have searched high and low for this issue. I have found a lot of forums on how to fix the problem but none of them pertain to my circumstances. I installed Omega ICS ROM v 13.1 a week or two ago. I then decided to install Omega JB v18. I then upgraded to Omega JB v21 as well. In preparation for the official Samsung JB ROM, I went back to ICS. I started by downgrading to Omega v13.1 ICS followed by stock Samsung ICS ROM I9300XXALE8. A couple of days after doing this, all of a sudden, whilst on a call, I lost signal and then the stop sign icon appeared in the top toolbar. I have no radio, no wifi, no bluetooth and no lock screen & power menu. After all of the reading I have done, I have managed to discover that my EFS has disappeared. I have rooted the phone and installed ES File explorer and have looked inside the EFS folder only to find that it is blank. I did have a Nandbackup but managed to delete it in my attempts to recover my phone (yes I know im stupid but I didnt realise the significance of the backup until I realised what was missing!!). So, no EFS backup. Seemingly nothing in the EFS folder on the phones root. Any help would be greatly appreciated. One thing I did notice, which I am sure is significant in some way, is that when I put Omega JB on it, my sdcard mounted as "sdcard0" or something along those lines. Again, because I am fairly new to the custom ROM world, I didnt realise the significance of this until I had down graded back to ICS.
Please help!!!!
Thanks again.

If you do not have backup of efs folder. You have no chance of getting imei back.
You can go to service centre for rebuilding efs folder.

Flashing any roms can destroy the EFS thats why its always rule one to backup EFS folder . Multiple flashing up down up down increases the risk .
Did not Omega backup your EFS .
You say
have no radio, no wifi, no bluetooth and no lock screen & power menu
Thats not the signs of IMEI corruption as it plays no part in power menu or lockscreen .

I think that S3 has some problem in securing it's EFS folder.
I flashed my S2 with hundred's of roms and never faced this issue.
Secondly in my experience lock screen and power menu is efs folder issue.

A reminder about 2 things:
1) swapping/changing/etc IMEI's is illegal
2) giving someone else your EFS folder wont work, your phone will just default to the generic IMEI which is normally no better.

Hey. This is one of the things I had read about and tried and it came back with nothing. I don't recall the error message but I think it said it couldn't find the partition or folder or something. I am certain that it has to do with Omega Jb and the fact that it installed and mounted sdcard as sdcard0 and somehow, when going back to omega ics, this has occurred. Another thing I have just now remembered is that I had also setup a swap partition on my ext sdcard and had it mounted. This was all working fine for a few days though so I don't see how that caused it. Was really odd. Anyways, thanks for all the help, but I am going to pay for it to be repaired.
