Copying a font in /system/fonts resulted in a 'read only file system' error.
Googling around looks that the /system folder is mounted read only.
How can I (temporarily) set this folder to read/write ?
By using a rooted file explorer or Super Manager .

Thanks, this works.
When I set /shystem to r/w I can manipulate files / copy files to this folder even from an SSH terminal from my Mac.
Worked extremely well!
Thanks for the help guys. I had installed Beans Stock Rom and lost my VVM support. The market even said my device was not compatible. Tried all prior versions of VVM and none worked until I got this file and used Root Explorer to install it and set permissions as described. Thanks heavens.

Ok so I have rooted my Hero and all is well. I've been trying to replace the sound files in system/media/audio/ui where the keyboard sounds are. I find that I cannot move a file into that folder, or apparently any of those folders. When I try to paste a copied or cut file using root explorer into the ui folder, the file just doesn't appear.
Why is this?

have you tried with and without file extention?
Yes. Root explorer just won't let me move any files around in the phone memory. Do I have to do it using adb?
I have a feeling its Root Explorer not working properly in Hero.
I could do this easily on my magic, but I get the same thing - looks like its copied the file, but when I paste, nothing happens at all.
I did manage to delete the Stocks app. from the device (don't use it or need it) using root explorer but other attempts to copy and pasdte have failed.
I have however managed to successfully use Astro File Manager to copy a wallpaper file from the device memory and paste to the SDcard. Will explore Astro a little further and see if it can do more on the device.

Phew, not just me being thick then....
I spent most of today trying to backup an .apk from /data/app-private to /sdcard. No luck with Root Explorer, adb pull or a 'cp' from the shell. "Remote file does not exist" was the result of the last two, but it's displayed by ls.
I think anything in app-private is a no go anyway as it contains copy protected apps. With regard to astro - it can copy from device in certain locations, and paste to sd to back up, but it can't delete from the device, and it can't copy or move files to the device.

Hmm, thanks Daisy. Will get on to the app's developer, as it was his advice to gain the ability to change location settings that I tried to follow.

Unless you made other changes than rooting, the /system partition is mounted read-only by default. As far as I know, you'll have to follow one of the root guides to mount it read-write (like you probably did to get /system/bin/su in place) and then do whatever changes you'd like.
Personally, I got tired of the boot audio real fast, so I changed useAudio in /system/media/boot_animation.xml from "1" to "0". Ahh, blessed boot silence...

Hi everybody
My problem is with my GPS signal. I searched in the forum and I found a topic ( http://forum.xda-developers.com/showthread.php?t=1060963 ) with a correct gps configuration. I followed the steps but when I edit gps.conf file I can't do becouse I haven't permissions. In other topic talk about how I can do to give file permissions with:
- adb shell
- su
- mount -o remount,rw /dev/block/mtdblock3 /system
I following this steps but when I edit the gps.conf file (with root explorer) and I put the new configuration and reboot the terminal, the file don't change and has the old configuration.
What's the problem? I don't know
Sorry for my bad english
Thanks !!
Your problem is that the phone is s-on. You can't edit /system when your phone is on. Boot into Clockwork Recovery, mount usb + system, and debug with abd or a program like Android Commander. Then reboot your phone.

Thanks you man !! I could edit the file and the gps works perfectly.
I hope this post will serve to other people's
Thanks for all !!
I've been away from a computer for a couple of weeks now, but I needed to edit my gps.conf yesterday, so here's what I did. It was actually pretty enjoyable.
I used Root Explorer throughout.
I created a new folder where I would carry out all of my operations on my SD card. I then copied the existing gps.conf to that folder.
Then I edited the file with Root Explorer's built in text editor and created a folder named "system" and a subfolder inside that folder named "etc". Then I moved gps.conf into "etc".
Next, I longpressed the "system" folder and zipped it. From there, I flashed it with CWM and the GPS has been working flawlessly since.

I don't knew this interesting way.
Thanks for share it.
I have installed the Deodexed 407 Rom, and installed Streakmod Recovery and also installed superuser.zip, so in theory, from what I have read my streak should now be rooted.
But when I try and edit a file, the build.prop file in /system with Astro File Manager I alter some of the settings and save it, but when I reopen the file the changes had not been saved. I have tried seeing if I can change the permissions on the file, but without success.
I would be grateful if someone could assist me in where I am going wrong, hopefully it is something simple or a wrong setting that I am not quite doing correct.

You have to mount the system as ReadWrite and there was no need for a new thread. You should've posted in the rooting thread
Sorry, for not putting it in the rooting thread, but didn't want to clog a general rooting thread with a specific problem.
I have solved this now thanks, but not with Astro File manager as I still cannot seem to change the permissions with that app, but used advanced tools app instead.
Thanks again anyway.
Yes i had same problem trying do root operations with file expert. I used root file explorer instead. Weird thing being that even with rooting permissions ticked file explorer failed.
For most root-enabled browsers, just enabling root permissions won't give you write access. You'll need to find a second option to mount the /system directory as read/write. That's normally somewhere in the Settings menu or on the directory's long-press menu.

It's mainly dependant on the kernel, all custom kernels automatically mount system as RW and all stock kernels mount it as RO
At least root explorer tells you that it's read only if you attempt to modify it without remounting, I havnt used ASTRO in a long time so I cant comment on that
Root explorer better for me

Hi,
I tried changing file permission on one of the folders where I saved my photos to read-only using "Root Browser Lite".
The following error message came up: "Changing permission was not successful. Please note that some file systems do not allow permission changes".
I tried using ES file explorer but it also failed.
Could someone please tell me how I could change the file or folder permission. I wanted to prevent the photos from being accidentally deleted by my children when I let them browse their photos..
My phone I9300 was rooted using CF Auto Root.
Thanks
Get root explorer, it's much better.
Simply long press on a folder and the permissions option is there.

Don't forget to set to rw at the top of root explorer before attempting to change permissions
If you're talking about the internal memory, you can do chattr +i /data/media/[name of folder] to set the immutable bit. EDIT: You need BusyBox installed for the chattr command
This works because /storage/sdcard0 (JB's usual mountpoint for the internal eMMC) is a fake FAT32 file system Google created for compatibility; the internal eMMC can really be found at /data/media, which is of the ext4 filesystem.
For the external memory, you can try SGS3 Easy UMS and set the read only property on the folder using your computer. (I can't find mattrib for Android.) There is no guarantee that Android/Linux programs will obey the RO attribute, however.
The reason why Root Browser Lite & ES File Explorer didn't work is because they work on UNIX file permissions, while a file system formatted using FAT obviously doesn't understand them - it would expect DOS/FAT attributes. That said, though, have you already backed up the data you consider to be important?
100% work

=============
Thank you all for your advice. The file system explanation betw FAT and ext4 fs makes sense. I have BusyBox installed.
Via Terminal Emulator, when I did "chattr -i /data/media/DCIM/Camera", I got a "permission denied".
Is there something that prevented me from this?
I'm running ICS.
Thanks
Did you type su before the command..
Just asking..

Thanks Zoot1.
I did that.
Image Gallary is still showing /mnt/sdcard/DCIM/Camera as "writeable".
What is the difference between two folders /data/media/DCIM/Camera and /mnt/sdcard/DCIM/Camera?
Thanks,
Note that I used +i in my example invocation of chattr. - removes the attribute; + sets it, which is what you want

Thanks qwerty12, after 'chattr +i folder name' , I return to root browser lite to change permission on mnt/sdcard/DCIM/Camera, I still get permission denied. What did I do wrong?

Mount System RW
The problem is that your system is currently in RO (Read-Only) mode.
Even if you are root, can't mess with system files if the setup is like that.
ES File Explorer works because it has an option (that DOES work) to mount the system in RW (Read-write) mode.
On my ES File Explorer Version 3.0.0 it goes like this:
Android menú button--->Tools---->Root Explorer--->Mount R/W.
Set: /system (or all of the options) to: RW----->OK.
Now, explore your files using the ES File Explorer interface on your phone and you should be able to erase every file and apk you want even if they are system files.

Hi,
I tried to edit the file "state" in "/sys/devices/virtual/switch/hdmi/" to unlock HDMI checking according to some internet posts I found. The problem is that it won't let me edit the file. I used Root explorer. My phone is rooted.
I also tried using Terminal emulator + Busybox to directly edit the file but it still didn't work. The file can be copied to other directory, and the copied file in the new directory can be edited, but the original file cannot be deleted or edited. When I tried to delete it, the message showed "Operation not permitted".
Any idea? Do I have to use "mount" command ? If so, please suggest. I am new to android and linux.
