and he asked me to learn busybox commands then I read this thread which offers an app to backup this folder

My question :Is there anyone who tried this app to backup efs folder on GSII ?
and does this app need rooted phone ?
Thanks
The commands are in the first link you posted, and yes you need a rooted phone.
I know but I need a way without busybox as It's very long
and I wanted to know anyone used the app which I posted on GSII
Just install the cf-root kernel, it has busybox built in.
Never used the app since it isn't needed, typing out a command isn't that trivial.

It's not hard, i just copy/pasted the commands from the first thread, but i know a bit about linux command line commands.
If you typo you could break stuff, that's life.
Or just try the app, maybe read the thread to see if other people have had it work for them.
The only risk free thing you can do with your phone is turn it off and put it back in the box

thanks for your help I really want to know a bit about these commands but I can't know how ? the topic give url to learn all commands not a bit of them
If you can tell me how I will be grateful
but as you know a bit about linux command you need to change anything in the commands or you just copied it ?
Thanks again for trying help me
If you are rooted you can just install galaxy s unlock by helroz and it has an option to just back up for /efs folder before you unlock. just select the backup option and don't do the unlock. No command line stuff required. The efs will be backed up to your phone storage.

Code:
su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs
The tar command with zcvf takes the input, in this case the efs folder and compresses it into a file in the output location, in this case on the internal sd card, while maintaining unix permissions, important for if you need to restore, this will make a small file.
Code:
su
cat /dev/block/mmcblk0p1 > /sdcard/efs/efs_dev-block-mmcblk0p1.img
Su gains root
Cat means catalog aka copy contents of what you point it at, in this case you are copying the whole partition where the efs folder sits.
In unix terms a folder can sit on any partition and be mounted into any point in the file system, just because a folder sits under "/" which is the root directory doesn't mean it's on the same partition, hard drive, or bit of flash memory.
We dump the whole partition so that if something goes wrong you can flash it back, i know heimdall which is an alternative flashing program can flash back different parts of the rom.
It's best to have both these backups to make sure and to give you different recovery options, flash via a program for the img or copying over the contents in the case of the tar file.
I hope this helps

Nope, but you can do it via a terminal editor on the phone.

To restore you can copy the contents of the tar file you made over the EFS folder, or if you ended up with an img flash it via Heimdall
ps dont share your EFS folder backup, as someone could use it to clone your phone

Crash could happen because you don't have enough memory. I did it for some system files on my phone and it always worked fine. But I always deleted the files I wanted to replace first

I would imagine adb would be your best option
Sent from my PG86100 using xda app-developers app
Oh GOD seriously?
Man you cannot replace the WHOLE system in any way except from recovery or bootloader...........NO ADB NO ES NOTHING will work.
ADB is feature that relies in the system of android. And when replacing the WHOLE system, the files needed for adb to work cannot change as they are in use, or if they change your phone will crash.
You can in no way change necessary system files while android is booted up beacause they are in use. Your whole operating system is in /system. Only recovery or bootloader will do.

Im pretty sure you can't. ADB commands does not work in fastboot and vice-versa. ADB only works in Android environment AFAIK. Though you can use fastboot flash commands and not adb push....

Yes, as long as they are not needed for the system to function properly. You can replace them with ES or Push them via ADB with root access.
Hello
Some of application such as Sygic, Aptoid, Waze and others cannot access to sdcard unless I reboot.
When verffying with Root Explorere I have noticed that the default access to Sdcard is R/O. As soon as I change that to Read/Write every thing goes right.
The problem is R/O keeps come back and apps cannot run until I do modification again.
Anyone can help please as to fix permenantly this issue.

There are two ways
1 the easy way is an app from playstore to do that at every boot
Are many can do this
2 the hard way is a script
You can paste it to init.d folder or script manager execute at every boot
Do you have gtab?
And sd card should not have sysrw option
Something wrong with install of rom

Peculiar problem. Will have to do some tests and look at some logs to find out the cause.
1. Can you create or delete files/dirs. on the SDcard, and do these changes persist after a reboot? Or do they vanish--like the changes never happened?
2. What's the output of this command right after a reboot?
Code:
$ [B]mount[/B]

There is no such device as a gTablet 7.7. Is this the tablet you have?
1. Use the standard file manager app and create or delete some files and directories on the SDcard. Reboot the gTablet. Verify that the changes you made remain after the reboot.
2. The $ character is just a prompt, used to indicate that the commands that follow can be executed by any user. Don't type that into the Terminal emulator app. Type in only the stuff shown in bold.
3. Setup adb (see the sticky threads) to make entering commands and collecting logs easier.
4. From now on post the exact error or diagnostic messages that you see. Or, make screenshots and post them.
I am very sorry to post my message here by mistzke.
Anyway I would like to thank all for your help and would like to inform you that the probme had been solved in installing a new tom.

I have tried a lot of custom Roms. I'm on Neat ROM Lite now. Not sure which ROM changed my file access permission settings to cause this problem but I'm not able to delete any files from my external memory card. I was able to delete when I was on stock rom. The other problem is for a few apps I get an error message which says can't install on usb/sd card. I have posted this in another thread
some time back but got no response. Some one please point me in the right direction.
This is what my file permission looks like.
PS: I am able to delete when my fone is connected to PC via USB. So I don't think it has anything to do with a faulty sd card.

Create a blank file and type that command in it. Now save it and rename it to 95mountsd with no extension
Now, if you have init.d support, place it in /system/etc/init.d and reboot
Command will run on every boot itself
Thank you, it worked. Now could please have a look at my other issue, in this post I'd be really thankful.
Can you please tell me what could be the reason for my default rw settings to change, coz I remember when I had stock os I never had to do all this.

Hello. I installed emui 9.1 on my mate20pro with the dload method. I unlocked the bootloader again and rooted the system with patched recovery. The phone is rooted, but the system partition remains in ro. I have tried various apps to mount the system in rw, but without success. I have also tried some commands found on the net both through adb and emulator, but nothing to do. I have also tried using rootexplorer which has been granted root permissions, but fails to modify anything, nor to insert or delete files within the system folders. What can be done?

it's the new filesystem called erofs (Extendable Read-Only File System)
So there's nothing to do?
Sorry OP if this is off topic , but its about magisk and root in 9.1
I have the "system partition remains in ro" issue too , its annoying yes , but I have a bigger problem
When "rooted" , the phone app ( dialer ), and the contacts app both get broken and crash .. So I have to fastbootflash twrp and lose root to make those apps to work normally again
Anyone with the same problem ?
I need root so I can change and use the font ( I like ) with a magisk module

Magisk can already 'replace on the fly' file from /system systemless-y.
It dies already support erofs.
Check Magisk documentations.
There is also a way to mount custom erofs partition....

Build your own erofs partitions (cf. erofs.mkfs)
Unmount stock ones and mount yours.
I just did some test 48h ago on erofs /cust and it seems to work...

So far, out-of-the-box, Magisk is already ready to replace systemless-ly files and paths on /system easily when used with modules.
-Module just need a a small tweak to add Magisk systemless-ly compatibility to other erofs partitions like /cust
Another way would be to bind or mount...

Hi, I saw that you managed to get a custom erofs partition mounted using magisk. I was wondering if the same could be done for the/product folder because that would allow me to fix the DPI scaling issues found on EMUI 9.0-9.1. Would it be possible to see the code for your magisk module?
Ok, So.
After having a look at what I did with this WorkInProgress...
So far there is 2 main way I thought about and played with:
Method A
A1/
Using the mkfs.erofs tool to make your custom erofs partition and mount it over the original one. (mayne umount it before)
Thanks @ph03n!x for his work on mkfs.erofs.
Thanks @ante0 for his android arm build.
A2/
I did not yet tryed to flash via fastboot or adb these modded erofs images.
Method B
What I'm actually doing is just mounting systemless-y with a magisk module whole folders over erofs one ;
In post-fs-data.sh, I'm doing:
mount -o bind $MODDIR/cust /cust
mount -o bind $MODDIR/version /version
With a ~150MB custom /cust it is working ; It should be tryed/perfected for bigger folders.
Another way, to not replace/spoof the whole folders could be to mount the whole list of custom files at their respective path (-to be tested)
PS: I'm not sure if update-binary module's file should be modded with some:
mount /cust 2>/dev/null

I'm rather new to this trying to do something similar on my EMUI9.1 using Magisk, I'm having a problem that i can replace anything in most other folders without much problem like /etc/ for example, but when i try to substitute /vendor/, whatever i put it the folder does not only fail to get substituted, it even disappears from the $MODDIR/system/vendor folder upon restart!
I.e. let's say I create a new file in $MODDIR/system/etc. Upon restart i'm successfully seeing that same file appear /etc.
However when I create a new file under $MODDIR/system/vendor, Upon restart i'm not seeing that under /vendor. ALSO the file is gone from $MODDIR/system/vendor like it was never there.
Any idea what is happening? I've also tried manually mounting in the post-fs-data.sh, where i put the following:
mount -o bind $MODDIR/system/vendor /vendor
That actually caused my system to freeze on the loading screen. I had to reset magisk to non-modded settings in order to get it to run again.
Any help's appreciated.
