use adb to copy it to your computer, save it and extract a copy so you can modify the copy.

Try creating a blank nandroid.md5 file with notepad and then place the same in the backup folder and then try restoring backup.

just save as .txt then change the extension to md5 using file explorer or similar.
if you long press on a file in file explorer it should popup with some options. Select rename and change the extension from txt to md5

[Q] Create a Flashable Zip Out Of a Nandroid Backup of /System

Hi, I've gathered some resources for creating my Touchwiz 4.0 rom but I need to know how to make a flashable zip from a nandroid backup of /system.
How would I do this?
Another question while I'm here.. I get this error when using kitchen: Imgur Link , any suggestions?

You don't need nandroid backup
Just need /system partition
Connect your device to PC
Go to platform-tools folders where you have installed adb.
Make a folder system in this folder.
Open Command Prompt in that folder and type
Code:
adb pull /system system
It will take some time.
When it's completed. What you have to do is replace the system folder in any ROMs flashable zip and modify it's updater-script to suit your needs
Thanks for taking the time to answer my question!

[TOOL][EFS][LINUX][ROOT]Simple efs backup S3 Mini

Hello XDA,
I wanted to share a simple script for Linux, that is backing up your efs-partition.
Instructions
1. Download the .zip file
2. Extract it
3. Open terminal and "cd" to the directory, where you extracted it.
4. type
Code:
./efs_backup.sh
if you got "rm failed for /sdcard/efs_tmp.img, No such file or directory", just ignore it
5. You can now find a file named "efs_backup_cwm.zip", you can flash it with cwm to restore your efs-partition
Why should I do that?
That's a simple question: Every Rom you flash and every root-app you use could have a simple bug and override/delete your efs-partition
What is the efs-partition?
It's a partition, wich is needed for any device-specific number like IMEI, Wlan-MAC-adress and so on. If it gets deleted/damaged, your mobile
will nothing more than a Mp3-player, unless you can flash back your old efs-partition.
Can you release it for Windows?
No, because I think every android-user should have linux installed on their pc and it doesn't cost anything. I have a dual-boot, too. If you want it on Windows, feel free to port it, it
won't be hard. If you want to install linux, I suggest you a debian-based distribution, because there will be the best support for android.
I WILL NOT ANSWER TO STUPID QUESTIONS!
I AM NOT RESPONSIBLE FOR ANY DAMAGE ON YOUR DEVICE!
THIS IS UNTESTED!
TWRP has efs as a backup option. But thanks for the alternative! I'll keep this one in case TWRP fails for some reason

i think you could always just copy the EFS folder with a root explorer, correct me if im wrong

Can't turn WiFi on after flashing.

Hey,
Today I used a ROM to flash my mobile (Samsung J5 2016 edition, model: J510FN) and I just used the perfect ROM, and it fits perfectly. But when I try to turn on WiFi it goes back swipe to off automatically when I swipe it to on.
I used this rom (version v1.1 because v2 and v3 were gone and bad): https://forum.xda-developers.com/galaxy-j5/development/rom-light-stock-rom-v1-t3467865
Someone knows what to do? I'm a beginner, so please explain it good. I have everything btw like Odin, TWRP, latest SuperSU, etc.
Please help.
Thanks
From your stock rom Copy the folder named Permissions from /system/etc and paste it at the same location in your new downloaded rom.
DONOT delete the existing folder , just replace the files.
Good Luck Cheers

You mean an img file , right?
If you have twrp or cwm backup of your stock rom , you can extract it from that file(ext4.system.tar.a) , if you dont have a twrp/cwm backup , you can try to flash stock rom from that img file and then copy necessary files into sdcard and then re flash your new rom and paste the existing files.
Good luck/

No, its an md5 file. Inside the md5 file (when I open it with winrar) it only shows hidedcache files etc and also boot.img
I need to have go to the patch (system/etc/permissions

Then you might need to flash your stock rom first and then copy the necessary files.
I have an Mediatek device , steps to troubleshoot are same , but I have a zip of my stock rom created to access stock files when ever i need them.
I would advise you to do the same for future troubleshooting..
Good Luck mate

And what are the nessecary files? Only the permissions folder or more?

Permission folder worked for me , but i would insist you to copy the entire /system partition as backup once you have flashed the stock rom just in case.
If permission folder doesnt work , then try replacing files starting with wlan from /system/lib/modules from stock to port
Do only when permissions folder doesnt work.
