Imei (efs) has flown down
how to properly recover or report a problem in the subject
AT: I have a backup of efs and it was made before imei and serial number went off.
ABOUT: There should be no problems. If the backup is not "empty", then efs will be restored. Set the phone aside and read all the instructions carefully.
AT: I made a backup on one version of the firmware (modem), but I want to restore to another.
ABOUT: We restore the backup only on the version of the firmware and modem on which the backup is made. It is important. If the version of OS and / or modems is different, then the probability of recovering efs is very small. efs since OS 4.1.2 (
firmware until July 2013 ) can not be restored to OS 4.1.2 (after July 2013) and to OS 4.3.
AT: I have a backup, but I do not remember from which version of the firmware (modem).
ABOUT: The answer is in the cap.
Determining the version of PDA / MODEM in the efs backup (efs, efs.tar, efs.img) AT: I have the same device. Can I restore a backup from it?
ABOUT: No, donor backup from another device is not suitable. All data is personal. Edit the efs section files in the hex editor does not work - the information is encrypted, the key is not matched. Edit build.prop useless
AT: I do not have backup efs.
ABOUT: If you do not have a backup, but after the loss of efs, you didn’t flash anything anymore, then the option of replacing .bak files in the efs section is possible.
1. If there is no root-access, then we get it -
Samsung GT-I9300 Galaxy S III - Official firmware (Post # 27590273) 2. Copy the efs folder to a computer or to an external sdcard 3. Check for the presence of files in the efs folder: .nv_data.bak
.nv_data.bak.md5
.nv_core.bak
.nv_core.bak.md5If any, then you need to flash on the previous firmware with the modem that was before the firmware. You can learn
So Delete files in the copied efs folder: .nv_data
.nv_data.md5
.nv_core
.nv_core.md5rename files: .nv_data.bak
.nv_data.bak.md5
.nv_core.bak
.nv_core.bak.md5to just deleted (i.e. remove the .bak extension in the title)
4. Move files to the / efs partition. 5. Set rights and owners for files / folders according to how it is painted.here How to set rights manually Reboot device AT: I have no efs backup, no .bak files in the efs section.
ABOUT: At home, you have only one way - patched modem firmware or stand-alone modem patch.
AT: Nothing helped me.
ABOUT: Contact the service or purchase a Samsung Remote Unlock Client program account.
If problems arise, all questions should be sent to the address of the service in which you restored efs or the Samsung Remote Unlock Client caliper, if you restored efs through it.
