You have to remount /system for write access. Default is read only.
Simply follow this guide:
"Once downloaded and installed, Open the
application and hit Menu, then tap "Settings",
this will bring you to the apps Settings Menu.
Once in the Settings Menu, scroll all the way
down to Root Settings . In Root Settings,
"check" Root Explorer and Mount File System"

If you're still having problems with this, I installed fx file explorer and fx file explorer (root add-on) apps from the play store. The apps were created by NextApp, Inc. The fx file explorer has a lock icon that you click on in the upper right corner that will give r/w capabilities necessary to save any changes.

The root setting is now in the menu. Select Root Explorer and you can set the correct permission

Please I rooted my samsung galaxy s4 two weeks ago and I want to remount the key but the file wont save after editing.Please someone help me to solve this problem.I used Root Explorer, es file explorer and fx file explorer but keeps failing.Please help me out.God bless you all

[Q] root access with ES File Explorer?

Will someone please help me get root access with ES File Explorer?
I was looking for a good file explorer utility with a root explorer feature. I already had ES File Explorer installed and saw that it supposedly has a root explorer feature. Well, I've searched all through it and I must be missing something because I can't find any way to explore anything on my NT except for the sd card.
I've went into the settings, down to the Root settings and checked Root Explorer and Mount File System but this hasn't seemed to help. I see no way to "get to" the root directory. If I try using the up arrow to move up a level in the directory tree, I can't get up any further than the sd card. It just say press again to close.
What am I missing?
Thanks to anyone that may be able to help get to where I want to be.

In settings, and you need to set home directory as "/". Then you'll have access to the entire file system.
What tgraves said as I have complete access to my nook with Es File explorer.
duh! That was so easy. Now I really feel like an idiot.
I think my wife is right. Sometimes I can make even the simplest things seem soooo hard...
Thanks for your help guys.

Not a problem
I wanted to say thanks as well as I was wondering the same thing today, didn't think it would be so simple as just changing the home
ES File Explorer Root
Good tip.
Thanks
don't worry... this was a great thread to start because i just found it with google and was looking for this answer also!
whoot!
Tell your wife she's always right
Trust me...
If you don't want to change your home directory to '/', you hit favorites and hit the icon that looks like a phone. That should take you to '/'. I think that's what the icon looked like. Anyways it's in the favorites menu.

I had been looking for the exact same thing. Thanks for your help.
I have the little phone icon so I assume I'm in the root directory. Next question - since this is where the additional 12 GB of space is, is there a "best place" to put my files that I don't want to tote around on my sd card? We're talking music, docs, etc.
Also - Is there a method so I can see "/" when connected to my laptop? Would rather move files directly to the root directory than have to copy to sd card then copy/paste to "/"
I find root explorer to be better.
Sent from my BNTV250 using xda premium
in the setting, tick all the boxes for "root settings" then from the "/" directory, you will be able to access the internal storage and others ( sd, 1gb space allowance)
What I meant was, is there any specific folder under "/" that I should put my own stuff in, or maybe create a new one?
B&N put all the reserved free space in '/data'. See this thread for workarounds. Accessing it via USB is another story, so you'll probably need to copy files to the 1gb partition then move it. Another option would be to use Wifi File Manager. Depending on the speeds you get via USB it may not be a bad alternative.
When using ES File Explorer to move music files from /data to /data/media it says "invalid path." When I tried moving it to a new folder I created under /data, it also failed.
Questions:
1. Is every folder under /data locked away from access thru ES File Explorer?
2. Is my only option to store content directly under /data?
Root the Access.
hi..
I have ES File Explorer installed and i want to install other font(.ttf). but when try to copy from sdcard and paste in '/system/font' folder, it shows an error : copy failed.
In Setting --> Root Setting, only first two options are enabled 1) Root Explorer and 2) Up to Root. other two 3) Mount File System and 4) Backup System Apps are disabled.
Also, when I try to check 1st one Root Explorer, it shows an error:
When 'SU Request' dialog popup, please select 'always allow'
can any one help me to install font in my android device?

Have you enabled Root Explorer's "Mount R/W"?

How do I set /system to read-write?

Greetings...I decided to create this thread to ask this question since the original thread was related to a different question...
A previous thread suggested to select mount r/w to enable read/write using Root Explorer...
I have ES File Explorer installed...Is that the same as Root Explorer?...
I select ES File Explorer and I can position myself on either /, /root, /system
directories but I don't see where I can select mount r/w to enable read write....
Sorry for the confusion, but I'd really like to get this resolved...
Thank you...
In ES file explorer go to settings scroll down, at the end you will see Root Settings with 2 options Root explorer and Mount File System check both.

Veronica(lavero.burgos) thank you very, very much!...Much appreciated...
I'm almost done...I've completed steps 1 - 3 below and saved it...
How do I complete step #4?...
(Again, THANK YOU very much!)...
___________________________________________________________
Method 1: Using Root Explorer
1. Set /system to read-write
2. open the file /system/bin/clrbootcount.sh in text editor
3. Add the following line at the bottom:
Code:
setprop persist.service.mount.umsauto 0
4. Save and set permissions to 755 (All Read, Top Write, All Execute)
In ES file explorer long press the file you want to change permissions, scroll down and select properties from the list. A window will pop up then change it like this:
User: check read, write and execute
Group: check read and execute
Other: check read and execute

That did it!...Many thanks again lavero.burgos...
Just one thing I want to point out - I did not see "OWNER" in the list, but "Other" instead...Does that sound right?...
So, this is how I updated the file:
User: Read, Execute
Group: Read, Execute
Other: Read, Write, Execute
Thank you...
Yeah that's fine sorry got confused with RT lol, just one thing User should be write permission and not "Other"

Assuming your NT is rooted or running CM, the "Mount R/W" option is on the "Root Explorer" menu.

Same here. Tried link2sd and it worked once until phone was rebooted, then it can't create script.
I found this at www link2sd info/faq:
In order to use Link2SD you need to do "S-OFF" to disable this NAND lock. (a.k.a. "NAND unlock" or "unlocking the bootloader")
So maybe the bootloader has to be unlocked to move apps to SD. ???

Hello Guys,
Hold ON!! Hold ON!!!
You no need to do all that stuff to increase your phone's internal memory. Using Link2SD on L9 for increasing memory is a HORRIBLE !dea.
If you have a Class 10 (at least Class 8) SD Card with good storage capacity then Just Follow Me:-
1. First Download This script file and Install SManager (free app) from the link below:-
Script
SManager
2. Now use a file manager with root access and copy above script file to /system/etc/ Folder of your device.
3. Run SManager, It will start with explorer. Tap on UP Arrow at top left until the first directory icon left only with "/".
4. Now tap on etc-> /system/etc, in list. It will take you directly to /system/etc/ Folder of your device.
5. Find extsd2internalsd-jellybean.sh file which you copied in 2. Step. Tap on it.
6. An open as ... dialog will appear. Tap on Script/Executable
7. Next dialog will appear with some icons and text with it.
8. Now tap on Su icon (Android with crossed bones).
9. Then tap on Boot icon (gear).
10. Now last one, just tap on RUN Button.
DONE
now go to setting=> storage and check the size of internal memory :silly::silly:
this tutorial will exchange your phone's internal storage with external storage.
and all this tutorial is not my work. All credits goes to Roker1, so thanks to him. Just explained it in a simple way that I am using my Self

Okay Let me clear your confusions.
Before copying script to etc folder es explorer have to obtain root access.
To do so, open es file explorer, tap in a small icon with a globe behind mobile, located at top left of ES file Explorer.
A menu from left side will appear, tap on TOOLS option, it will get expanded.
Now scroll Down until you see ROOT Explorer option with on OFF button.
Tap on OFF button in front off Root Explorer. A message or dialog will appear asking to allow root access to es file explorer (if your l9 is rooted & super user is installed).
Tap on allow. Now the off button should change to ON. Thats it, ES file explorer has gained root access. Now try to copy that script file to etc folder and then follow rest of tutorial.
if still you are confused, let me know
gdjindal said:

After looking your above queries, it look's like you are not familiar to android development or to any other programming languages.

Root permission is getting denied because your es explorer is not allowed. to do so i have updated my last answer just chk it out.

Thanks gdjindal! I have some questions.
Does the SD need two partitions? Does this move any system apps to SD? Does it automatically move EVERYTHING else to SD or just apps newly installed after setting this up? Can you control which apps to move and/or move things back to internal? What happens if your SD card fails? Can this setup be uninstalled and revert back to stock? Do apps operate much slower running from SD this way?
Thanks again!

I believe so. Root Explorer is "on" and Mount R/W permission is set as Path/ =RO, /persdata/absolute=RW, /system=RW, /firmware-mdm=RO.
Does that sound right?
OK, I went ahead and bought "Root Explorer" and was able to copy the Calendar apk into the system/app folder. But I still can't get it to install. system/app is mounted as R/W but when I tap on the apk and run "install" it says "application not installed" every time. Any ideas why? FWIW, the apk is "SecCalendar_NAmerica_SPen.apk" and should be the apk for the stock Calendar app.

The not installing is normal, see what permissions another system app has, apply the same.to the one youre copying. Reboot and it should work.

OK, I'm now stumped. I've changed permissions and "owner" so it's identical to all other .apk's in the system/app folder. But after rebooting it still isn't installed. It looks right in the system/app folder, but the application is not in my app drawer. (No icon, widget, etc.) Any other ideas?
I know this is old but I'm having the same problem. The file is Read Only and I can't figure out how to change the path so that I can copy it to system/app.
Thank you
