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.

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?
Hi all,
I have a Samsung Galaxy S4 (Value Edition) GT-i9515 bought from Soudi Arabia. Since the device is not registered on any passport, its IMEI was blocked in Turkey. Shortly, I have to change its IMEI.
- The device is not replica so I cannot use MTK Tools (ie. MobileUncle).
- Device has a Exynos processor, so QPST does not work also.
So I have tried to change it manually in EFS and the strange thing comes here:
When I have dialed *#06#, I see the original IMEI, no problem. However, I cannot view the IMEI in EFS backup.
I mean, I have backed up the EFS folder with EFS Pro and it has generated a file with "tar.gz" extension and a file named "efs.img.ext4" in it.
When I opened that file with Hex WorkShop and moved to 0x80000 BOOM: While I expect to find the IMEI there, it is ".;9........S..." (where "dot" denotes null)
Here comes the question: Where does that device store IMEI number and how can I change it without a box?
Thanks,
NOTE: Since there is no subforum for GT-i9515 under S4, I have opened the thread here. I suggest to add a subtitle for GT-i9515 under S4 forum. Because that model is so problematic

Changing IMEI and such is not allowed to discuss on xda.

Hello.
When I changed ROM, both IMEI numbers were deleted. The phone options are "unknown". Besides the IMEI number all the information is correct - I have a good MEID, IMEI SV, Wifi MAC, Bluetooth address.
I have a copy of the NVRAM partition .qcn however, when trying to restore by QPST I get an error "The ESN on the phone does not match the ESN of this file containing RF calibration data".
When I try to save IMEI via Qualcomm_Smartphone_Write_IMEI, it pops up an error reading "Read IMEI1 fail!".
By changing the value of parameter 00550 in the QXDM and using WRITE, the value 0x00 is still read after the parameters are read again.
Please help me how can I save my phone. I was desperate.
Could someone be able to share a copy of EFS with TWRP?
My model is 2016031.
Rom: Global stable 8.5.3.0 (MALMIED).
Please help and apologize for my bad english.
