Hi all, i've purchased an SM-G900F but there is a problem, it has rooted.
I've noticed those :
- I can see IMEI number (if i do #*06#) but my EFS folder is empty
- When turn on WiFi , the device will reboot automatically and appear " Factory Mode is On"
- i can make first call with sim , after i'm unable to call , but the 3G network works
- Whit ES File Explorer i've see that my efs folder is empty (But i can see my IMEI with secret code)
- In Device Info i see one time "Official Status" and another time "Personalized Status"
I'm tinking that old owner is a very st......d guy. Howewer these are all information :
Model : SM-G900F
Version : 4.4.2
BASEBAND : NE2
BUILD : NE2
What do you think? How i can solve the problems?
EDIT 1 : i've formatted from recovery , now it ask me to insert the samsung account of old owner...
- Use Phone INFO ★Samsung★ app to obtain more detailed information about your device, including Model, Baseband, Bootloader, CSC, IMEI, S/N, etc...
- May be the Reactivation lock has been enabled. You should ask the ex-owner for the account.

reactivation lock is on. you will need to contact old owner. There is also a way to "fix" that but not sure if it is appropriate for XDA.

The guy was not traceable now. He's vanished ....
You are kinda between a rock and a hard place if reactivation lock is enabled and you don't have the login to toggle that. In most cases that means that the phone is stolen and this is an explicit anti theft feature. You need that login from the original owner. Or if you have the original receipt, you might be able to convince a Samsung repair center to disable the reactivation lock for you.
In any event, as to your original question the most likely cause of the problem is a corrupt configuration file, namely a text file named "factorymode". You can try this repair from the command line or a root aware text editor.
Code:
echo -n ON > /efs/FactoryApp/factorymode

Great. But you neglected to tell us if you tried (or even noticed) the suggestion to check your factory mode configuration file. The contents should show "ON" (yes, "ON") and the permissions 0644. Your efs folder may appear empty to you when it really isn't. It depends on whether you have your file browser (or command line options) set to display hidden and system files or not.

y factory mode is on , because i can't acces my wifi, and it appear that factory mode is on. I've set to see hidden files , but now i haven't root on my device
Edit: terminal emulator say : no such file or directory
Edit 2 : Solved with terminal emulator and busy box Thanks to @leoaudio13 for his dump
These are the command for mount efs :
su
mke2fs /dev/block/mmcblk0p12
mount -w -t ext4 /dev/block/mmcblk0p12
reboot
After then , with text editor i've disabled FactoryApp in efs folder tanks to all
.
For the benefit of anyone else reading this thread, do not repeat the steps in the post above until
you understand what they do. A typo in those steps could easily cause you endless grief.
Glad you go it working.
If those steps fixed your issue, then you mislead us with erroneous information earlier. You said that you had an empty efs folder earlier. But those steps would not have been necessary or effective if that was accurate. You must have had a missing efs partition. There is a considerable difference between an empty and nonexistent item and that datum would have led us to a solution.
On a normal phone, there would be an extant efs folder and it would be automatically mounted at boot. A missing folder strongly suggests that the wrong firmware or a flash error took place. Presumably by the previous owner.
Anyone using the make filesystem command mke2fs /dev/block/mmcblk0p12 should be very careful with typos as an incorrect address could cause major corruption that would be difficult to recover from.

Ive got almost the same problem, i bought my s5 to a friend who visited Philippines from Korea, He acquired the Phone in a Pawnshop in korea, i restore the phone and now it asked me for a password which i dont know, send it to the Technician, Force to delete the account (dont know how) but the problem is that, Phone has NO SIGNAL from then on, it has a NO signal above instead of a bar signal, EFS folder is empty, IMEI was null 000000000000000.
Anybody has the same experience? how can i fix this? please help.

could be a block imei by the operator? if it is POSSIBLE to solve? or it could be due however to the efs folder, or the firmware, modem?

it's a different problem , you have a null imei , in your case it's more difficult to resolve.

As you can read i said, Ive got almost the same problem, i don't say we have the same problem. in a sense that previous owner account or the reactivation lock is present. sorry if i made a statement that bothers you, just looking for a solution.
hello guys, always about the efs folder I was reading this post: http://forum.xda-developers.com/showthread.php?t=2705524.
according to you through this tool is possiblile restore the backup I had done with samsung tool? I would like to try this because the efs folder on my sm-g900f is 23kb, but the backup I had done with samsung tool is 14mb !! what do you think?
Need stock SystemUI.apk and SystemUI.odex for tab 3 7.0" (SM-T210).
I tried to change the notification panel and screwed up. I REPLACED the STOCK System.apk and DELETED the STOCK System.odex without having a backup. After that the notification panel is gone and the background turned black but i can still use the tab.
Any advices?? ??

If you search your Build Number you will find a full firmware you could flash
Is rooted ?
I wonder what a factory reset 'available from menu' would do ?

Tried factory reset but the prob still remains. I think factory reset depends on the files on the root folder of the device. So if i change or delete something in the root/system/... . Factory reset will just erase the files outside root folder. Its juz my understanding though. ?
Install stock firmware for your device, and always make a nandroid backup.
Hello XDA...
Ive been reading up on this for a few days and im confused and curious.
My IMEI is showing unknown in about device / status and entering *#06# into the dialer shows / 17. The weird thing is 4g LTE, MMS, SMS, and phone calls all work. I got the phone off of eBay already Sim unlocked. Since then I have rooted the phone and updated to official 4.4.4.
I did some research and I read that the IMEI is stored in the nv_data.dat file which I do not have in my efs/imei directory. I use Root Explorer and I have it set to show hidden files. As I said I got the phone off of eBay so I don't know if it was unlocked using a code, a box, or if it was factory unlocked.
Here is what im wondering.
#1. When you sim unlock a phone does the nv_data.dat file disappear? (This might depend on the method? Maybe? IDK...)
#2. Does 4.4.4 handle the storage of the IMEI differently? If so how does it store it.
#3. Can I get the IMEI to show up again?
I do know my IMEI as it is on the sticker behind the battery along with the model number and serial number. But why android isn't showing it is really bothering me.
Additional Information that might help.
Model = SGH-I337 (AT&T Branded)
Android Version = 4.4.4
Rooted = Yes
Busy Box = Yes
Baseband version = I337UCUFNJ4
IMEISV = 17
Carrier = NET10 (Using NET10 AT&T Sim)
If additional info is needed please ask. I have tried to give all the info I could think of that would be useful to this question.
Thanks in advance for your time and patience.
