[TUTORIAL] Remounting/restoring/backup the /EFS partition

/EFS partition contains a lot of information about your phone, f.e: wifi/bt mac address and your IMEI (nv_data.bin).
It's highly recommended to backup the whole partition, or at least copy the files from the efs directory.
CORRUPTED OR NOT?
You can check if the efs is mounted or completly damaged with this command:
adb shell
mount
You will see something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Red part means /efs is mounted.
IF YOUR PHONE HAVE CORRECT EFS PARTITION:
1, Root your phone - there are several methods to do this.
2, Install root explorer or Estrongs file explorer and copy /efs dir to your sdcard - this will copy the files.
or
2, Make a backup from the whole partition -this is better if you flash a phone with wrong ops, the only way to restore using this backup.
Backup:
adb shell
su
dd if=/dev/block/stl4 of=/sdcard/efs.rfs
Restore:
Add efs.rfs to an unix compatible tar and flash with odin as efs file:
IF YOUR PHONE /EFS IS CORRUPTED:
Flash the included /efs tar with odin:
This will remount your efs partition and (if you have a backup or fixed nv_data.bin) you just need to overwrite files with a file explorer.

confirm WORKING 100% ... all you just need later is the nv_data.bin fixed
Thanks so much for your efforts

I am using I5801 JPB (with restored bootscreen and Rooted via SuperoneClick)
while using "adb shell" command at Better terminal its showing "adb: not found"
I flashed my I5801 from JP9, JPA and JPB till date..
is it possible to restore the backup now..??

Because you need adb.
If you do on phone (Terminal emualtor) adb shell not needed, just su and the other commands.

how to make .tar file because backup file is .rfs format help me i want my imei back

ok, using the dd method i made the backup of my /efs to a efs.rfs file that have ~4 MB
But when i go to the efs folder (on / ) or see the copy i've made to my SD card, there is no files at all on this folder. How can we "see" those files (nv_data.bin) ?

Hi
For backup I simply copied my /efs folder to SD card using root explorer.
Then I modified nv_data files to get unlocked.
there was no SSNV in the files.
I have a working unlocked phone now but the problem is that IMEI is all zeros like 000000000!
Can I use that folder to restore my files?

Download the Tar Utility from GnuWin32's SourceForge Page.
Code:
hxxp://sourceforge.net/projects/gnuwin32/files/tar/1.13-1/tar-1.13-1-bin.exe/download
(change it to http)
It'll install the tar.exe executable and required dlls in C:\Program Files\GnuWin32\bin
Copy those to where you have your rfs (or you can add the bin folder to your PATH Environment Var, google for help on how to do that)
Now type:
Code:
tar -cf efs.tar efs.rfs

Yes, you can, just copy nv_data to /efs.
Windows users can use IZARC to create tar files.

HI,I am having LG F500L,running Android 5.1,build number LMY47D,sofware version F500L09a. At first, I backup my system img to the phone memory. I typed these commands
Send_Command.exe \\.\COM3
then type id
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img.
After done, I opened my phone storage then there is a file named system.img.
Then I downloaded rooted img F500L10w online provided by a forumer. I renamed it to system2.img and copy it to phone storage. Then I open cmd typed these commands
Send_Command.exe \\.\COM3
then type id
dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0
After done, my phone reboot and stuck at LG Logo screen.
OK,then i want to flash back my stock system.img. I type these commands again.
Send_Command.exe \\.\COM3
then type id
usually it will show uid=0(root) gid=0(root) context=u:r:recovery:s0 , but there straight show # after 1 seconds.
Then i type dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0
after 1 second it show #
Now my phone stuck at LG Logo screen. I cannot flash back to stock img. Can i know how to solve this?Thanks.

Partition "persist" erased! Dump needed [Redmi Note 4G single SIM]

Hello everyone,
Let me explain veeeery briefly my story.
During an update, the phone froze and I had to turn it off. I'll spare you all that happened next, but in practice "cache" and "persist" partition have failed.
Now, the first one is minor and I could rebuild it and format it without much thought, the second one, unfortunately, I could not retrieve it and I was forced to do the same thing. Too bad that the "persist" partition holds all the necessary configurations to operate the various sensors of the smartphone.
Always avoiding to tell you all the attempts I made (and trust me, I made them all), the last remaining solution, and probably the working one, is to get a dump of the "persist" partition to flash via fastboot. That is, I need a backup of this memory space (taken from a Xiaomi Redmi Notes 4G (Qualcomm) - single SIM, working of course).
Here's how to create this file, then you will have to send it to me (There are few simple steps).
-----------------------------------------------------
Connect the phone to PC with USB.
First, verify that the device is responding ADB (Use ADB while the phone is in recovery mode, as a matter of privileges)
Code:
adb devices
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you see a character string, then the device is connected.
Now enter into Shell and check the "persist" partition number
[Each line is a command where to give ENTER - After the # I just put a comment. Type just the previous part.]
Code:
adb shell [B][COLOR="DarkRed"]#Enter into shell[/COLOR][/B]
parted /dev/block/mmcblk0 [B][COLOR="darkred"]#Start a tool to manage partitions[/COLOR][/B]
unit MB [B][COLOR="darkred"]#Set size in MB[/COLOR][/B]
print [B][COLOR="darkred"]#Display the partitions list[/COLOR][/B]
You should see a partitions list. In my case (and probably in all the Xiaomi devices), the "persist" partition is the #26.
At this point it's possible to dump (Backup) that memory space.
If you are still in the "parted" tool, then you need to quit it first, typing "quit", to get back in the shell (but without going further out from the shell)
Code:
quit [B][COLOR="darkred"]#Quit the "parted" tool[/COLOR][/B]
dd if=/dev/block/mmcblk0[COLOR="SeaGreen"][B]p26[/B][/COLOR] of=/sdcard/persist.img [B][COLOR="DarkRed"]#dump from partition #26, one highlighted in green (persist), making a file into internal memory[/COLOR][/B]
Done!
Now you have just to take that file and send it to me. If you want to continue using terminal (since you have already), you can copy the files to your PC as follows:
Code:
exit [B][COLOR="DarkRed"]#if you are still into shell, then you need to exit[/COLOR][/B]
adb pull /sdcard/persist.img C:\
Now you copied the file (that was created into internal memory) to your PC, in the C: \ drive
Please attach this file on reply.
Thank you!

G2 No Network ISSIUE

Hello everybody.
I am having a big issiue with my G2 right now so i thought that i can fix it asking here.
My problem is that recently i was loosing my mobile network connection and for this reason i decided to restore the stock firmware on my device ( I was using CloudyG2 ).
After i restored the stock firmware the mobile network is working great but after a simple restart or power off and boot again the network itself dissapears. After a couple of tryes i noticed that the fields called Baseband and IMEI are the right ones but after the reboot they both become Unknown. I also noticed that the firmware once installed the stock one is V30d-EUR-xx but after the reboot it is just V30d.
I wanted to ask what can i do to fix the problem? After the reboot i am seeing the ANDROID IS UPDATING screen but for less than 8 seconds. I think this is why the network dissapears and i loose connection and the firmware name changes. Can it be that android updates after it initializes all the applications and this shadow update make my phone unusable?
I wanted also to say that i tryed to use BlissPop or Cyanogen ROMS and the network work perfectly with those, it is not about 3G or LTE band being not compatible. But still i would like to know why i get this problems. I also want to say that i, one time, flashed the phone using the TOT flash method but that flash mode is only for US AT&T phones, so for this reason maybe i loose the network. I returned to stock using the KDZ firmware.
I am ataching the screenshot to explain my problem better, just in case, sorry but they are in italian.

Thank you, if you have any questions please ask me

Maybe the only thing i can do is restore every single partition with a working D802 32GB european phone.
Can someone please run this scripts in a terminal ( phone needs root access ) and share them with mega? Thank you

OEM_NV_BACKUP The NV partition is invalid!

Hello experts!
After updating to OOS 2.2.1 through stock updater, after reboot I get:
Code:
OEM_NV_BACKUP The NV partition is invalid!
Of course, no IMEI, no network on both SIMs.
Been googling all day, to no avail.
No root, stock recovery, EFS available.
I have tried:
This one:
http://forum.xda-developers.com/oneplus-2/general/guide-official-stock-reset-to-oos-2-2-0-t3290707
And this one, similar to first one:
http://forum.xda-developers.com/showpost.php?p=62440352&postcount=21 (Oneplus Two - Solution for Hard Bricked Device).
Is there a hope or I need to send it to repair center?
Tagging @Zyxxeil @Lord Boeffla, maybe some ideas will pop up.
EDIT:
EFS backup restoration in TWRP does not fix it.
Thanks in advance!
Juraj

do you have any back up of your EFS partition in twrp backup?? if you have restore that partition and see.

As said....no.
TWRP did not backed it up.
Any other method/idea, ayone?
EDIT:
Just figured out that I have EFS backed up (oem_stanvbk.emmc.win). I will restore it from twrp, lets see how it goes.

OEM_NV_BACKUP The NV partition is invalid!
Of course, no IMEI, no network on both SIMs.
Been googling all day, to no avail.
No root, stock recovery, EFS available.
I have tried:
This one:
http://forum.xda-developers.com/oneplus-2/general/guide-official-stock-reset-to-oos-2-2-0-t3290707
And this one, similar to first one:
http://forum.xda-developers.com/showpost.php?p=62440352&postcount=21 (Oneplus Two - Solution for Hard Bricked Device).
Is there a hope or I need to send it to repair center?
Tagging @Zyxxeil @Lord Boeffla, maybe some ideas will pop up.
EDIT:
EFS backup restoration in TWRP does not fix it.
Thanks in advance!

Can someone please check what files are inside TWRP EFS backup?

I have exactly the same.
Why restoration of it does not solve it?
If I pull
/dev/block/mmcblk0p10
/dev/block/mmcblk0p11
with dd:
dd if=/dev/block/mmcblk0p10 of=/sdcard/modemst1.bin bs=512
dd if=/dev/block/mmcblk0p11 of=/sdcard/modemst2.bin bs=512
to sdcard, they have 1M each, whilst backup is 10M.
Can anyone try the same?
EDIT:
above mmcblk is for OPO, OPT has /dev/block/mmcblk0p20.
And size is ok if I do dd with it.

bump, anyone?
