Hi,
Two days ago I've flashed a new ROM, and that caused my IMEI to get generic (004999010640000)
I have a backup of the efs folder!!
But every time that I erase the efs folder, It's being re-created automatically...
I don't know how, and what makes it happen...
I can't restore my backup... it's always get overridden by something..

I know on the Vibrant you had to backup the efs folder so that you don't screw up your IMEI when flashing custom ROMs. Is there a similar folder on the G2X that needs to be backed up in order to prevent the same thing from happening?
I got the EFS backup, My efs.tar generated by EFS Professional is about 20MB, reasonable size for the whole EFS Folder???
Why does it get erased after i re-boot?? How can I Restore, and keep the restore in???

Hello, i performed an EFS folder backup using EFS Professional. My question is, why it needs Busybox to work? I must have Busybox installed if i need to restore the EFS folder? I'm on 4.2 stock and rooted.
PS: the backup went ok, no errors. There is anothe better way to backup EFS on gt-i9105P?
PS2: Restoring a nandroid backup, also restore the EFS folder?
there is very little chance that your efs folder will be blown up .. now that you have a backup , you need not need to worry .. while flashing roms and wiping dat , and restoring roms via cwm backup and restore you only need to restore the rom and not the efs folder backup .. if in case , you do not find your imei no. or your efs folder and stuff , you can at any given time restore it manually .. correct me if i am wrong but that is how it works . all the best and Happy Flashing
Hello peopleI am new to the S7 devs, since I've been browsing in the XDA S7 forum I've noticed a lot of people that lost their IMEI or corrupted it during installing custom ROMS.
It feels so bad even to imagine it, I was wondering if there is someone who can explain what makes a ROM corrupt IMEI or the EFS partition, and why some ROMS does the damage to people and not for others?
And whether having an EFS backup can save you in all cases or there are some cases where you really have no hope even with a full phone backup (all partition included)?
I am a big fan of custom ROMS but unfortunately, I can't afford to lose that phone at the moment.
So I was hoping that someone will shine some knowledge by answering what I asked and also provide some advice to do in the future to avoid as much as possible to end up with a Bricked phone or a useless one without IMEI.
Thank you very much in advance and don't be lazy on typing some lines that might help some people even if it's not me at the moment

What is EFS?
The EFS refers to a folder called EFS which can store information like meid, imei, serial number, config, diag settings and radio settings, etc in an encrypted format at the file system level stores. So it is very neccessary for us to backup EFS before flashing ROMs.
How will you lose the EFS folder?
How will you lose the EFS folder?
As far as I known, you always lose your EFS by mistaken operations. For example, flash ROMs or wipe data using an uncorrect method. Even wrong power on & off ways like taking out the battery to force shutdown as starting could corrupt your EFS, too. Rooting and flashing ROMs usually have no influence on EFS data, but you know everything can happen in the real word. There are some ways you can check whether your EFS folder is lost: inputting *#06# on dialler, going to settings/about phone/status or checking mac address.
What results if you lose the EFS folder?
The loss of the EFS folder may bring about an incredible disaster on your device such as no imei information, base band unknown, no radios and so on which mean your device will no longer be recognized by your carrier. After knowing that, won't you back up the folder?
How to back up the EFS folder?
Bofore backing up the EFS folder you need make sure your Andriod device is rooted. Then, install Custom Recovery on your device. Open the Custom Recovery, select the Backup option, and go on select the paritions containing EFS, then "Swipe to Back Up" to begin the backup process.
There are as well two Apps from wanan to backup your EFS one is EFS Backup and the other Partitions Backup
Always remember before playing with your phone, to read a lot, and always do BACKUPS
I lost the funcionality Phone in my N8000. I think i lost the imei e someone more else. How can i restore my efs? I have a backup of my efs in format zip and format tar made 5 years ago ( i dont remember what application i used) , but i can not install via Odin or via Twrp, said Invalid Zip format on checking Digest File. I think the problem is checking the md5 generation that is not compatible with Odin and Twrp.

It is not solved, when reboot the system, the imei of phone, N8000 is another, is from another file from i used to recover.
Manually from my backup what files and permissions i have to copy to the /efs in root of my N8000? First i copy nv_data.bin, nv_data.bin.md5 and the folder /imei and works. I do not known the original permissions of the files, perhaps now the problem is this.
Someone can help me?
Thanks
