You should backup your efs before installing custom rom. Mines has been repaired. Thanks to my friend who give his efs folder.

This is because /data is not mounted...
You have to go to recovery mode to mount & push.
You can also try the PC-Suite in my signature, which will do this all automatic

Oke, choose backup rom from Rom Manager. It rebooted my phone, did a backup for:
Backing up boot,
Backing up recovery
Backing up system
Backing up data (took some time )
Backing up .android_secure
Backing up cache
Backing up sd-ext
Generating md5 sum
Reboot my phone. So now I have a nandroid backup from which I can always recover right?

Help me to recover my IMEI (nv_data.bin)

I tried to delete nv_data.bin and nv_data.bin.md5 in order to recover original version from .nv_data.bak and .nv_data.bak.md5 after reboot but failed.
Firstly I remounted efs partition with -w flag:
Code:
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
First file've been deleted but for second message 'read-only system' shows up. And when i unmount and then mount again first file appears again.
I tried to do these from terminal emulator, adb shell from booted phone and in recovery mode (with CF4 installed).
My firmware version XWKE7. I bought phone as sim free at clove.co.uk
Can anyone suggest what can i do?
From what I have read from the SGS forum if your efs folder is missing your imei your stuck, only thing to do is flash some stock FW from odin and return it, hope you can return it under warranty mate.

[Q] efs folder empty, 'E: unable to mount /efs' error

So I think I lost the efs files while flashing cm10.2. I do have it backed up in my stock rom,but I can't restore it because of a 'E: unable to mount /efs' error in twrp. I still have my IMEI, can make calls and sms, but the efs folder is empty according to root browser, es file manager and twrp. What can I do to fix the unable to mount /efs thing? Thanks!
EDIT: I'm using a GT-i9505
If you don't succeed otherwise flash full stock rom with PIT and restore your backup. Backup internal sd first.

I wonder if you can take your backed up efs folder and push it back onto the phone with adb??
Or, download EFS12.tar file then flash it, you done.

That is not for I9505, for I9505 u can clear EFS without risk. The problem is you already have a couupted EFS file, so no point to backup it.

So im working on trying to get twrp up on the HD 8 but i need a backup of someones elses recovery. Its located at /dev/block/mmcblk0p7
Update please if you have root, go to adb then type adb shell and then su. after that just run this command dd if=/dev/block/mmcblk0p7 of=/storage/sdcard1/recovery.img, if you want it to go somewhere else then just change the part that says storage/sdcard1(for example if you want it to go to the device storage then just remove the 1) the recovery image should then be on your sd card. please then attach or send the recovery image to me. Thank you

[needed]persist backup of moto g5 plus which is not bricked yet

Hey guys as you know that we are able to get back volte successfully in Moto g5 plus by restoring PERSIST BACKUP.
So I think MAYBE persist partition got corrupted during flashing back stock.
But that backup is from MOTO G4 PLUS ,and some user facing a problem that whenever they reboot volte and imei again gone,and Everytime they have to restore efs (maybe because of that persist partition)so I am requesting you ,can someone please pull out persist backup of STOCK MOTO G5 PLUS WITH WORKING VOLTE (OR G5 PLUS WHICH IS NOT BRICKED YET).
I AM ATTACHING A TWRP FOR TAKING BACKUP WHICH IS MADE BY DEVELOPER.
SO YOU HAVE TO JUST GO IN TO BACKUP AND TAKE BACKUP OF PERSIST PARTITION
You can download twrp from below link.
https://potterroms.ddns.net/TWRP/twrp-3.2.1-1-potter_persist.img
I am not responsible for any brick/damage caused during you taking backu
Alright, so I got a Persist backup using the partition backup & restore app. I don't use VoLTE, but my IMEI hasn't become zero. I'm on Oreo. It's saved as a .img file. If this is helpful I'll upload the file. @akshu2697

DELETED
With a lot of research, I was able to dump the persist partition using adb. My dump will do no good, as I have only been able to get persist back by OP's method. We need someone to dump who has not flashed an oreo rom. Ok, that being said, here is how.
Make sure your phone is rooted.
Make sure usb debugging is enabled.
Boot phone into recovery.
Open adb with phone connected to pc.
Code:
adb devices
You should see your device listed.
Code:
adb shell
You should get ~# and something like a backward arrow [6N. That was mine yours may differ. If you have ~$ instead of ~# you are not rooted properly. If you used magisk you may have to add the sudo module.
Code:
ls -al /dev/block/platform/soc/7824900.sdhci/by-name
This will give you a list of all partitions. Look through them and find one described as persist. Mine was this:
Code:
lrwxrwxrwx 1 root root 21 Jan 1970 persist -> /dev/block/mmcblk0p30
We are interested in the address /dev/block/mmcblk0p30.
We need to type in
Code:
dd if=/yourMountingPoint of=/yourDestination/partitionType
where /yourMounting point is the persist address, if like mine /dev/block/mmcblk0p30. /your destination will be where you want to save it, and partition type should be persist.img.
My command was this
Code:
dd if=/dev/block/mmcblk0p30 of=/external_sd/persist.img
This will give us a proper persist .img file.
Here it is.
I clean flash stock rom (potter_NPNS25.137-93-4) before getting the persist file, was on crDroid 7.1 before. I don't know if volte is working because we don't have it on my country, but I never flashed Oreo before and never lost imei or 4g/lte, so it should be fine.
Hope it helps us and use at your own risk.

Aren't you the OP of this? I thought you needed a way to dump the original partitions, and I provided the method with step by step to do so. I've never coded for android systems, but I'm very familiar with close cousin linux, so I suppose I could investigate and learn. However I would think whomever developed the G4 plus method could use the above dump for our phone. I guess I assumed it was you who discovered this method. I'll dig into it further when I get some time, but getting the clean persist dump was what was asked to do.
I was able to write the above persist.img file by:
1. transfer persist.img to my external_sd
2. booting into twrp
3. opening terminal
4. entering
Code:
dd if=/external_sd/persist.img of=/dev/block/mmcblk0p30
However, this placed my EMEI to 0, and I had to restore my saved efs with moto g4 + persist to get signal back. But remember, I had problem with efs every time I reboot, so my case may not be typical of those of you whose moto g4+ persist was working fine for. I would be curious if N1vBruno's persist was at the same address as mine, namely
Code:
/dev/block/mmcblk0p30
Guys who have restored their VoLTE, does your IMEI match the one that came with your phone or has it changed to something else?
I'm just being curious as I thought using someone else's persist backup would restore his IMEI to your phone, or was it efs?
Please correct me if I'm wrong.
