Read-Only Filesystem?

---

Hello, all!

I'm trying edit a file in /etc/ and adb says 'Failed to copy: Read-only filesystem'

Now, is this actually true? Or is this simply a permissions issue? I'm doing this on a non-rooted phone, so I can't 'touch' anything without permission errors, but is it a futile task if the filesystem is read only anyway?

I'm trying to do this from a non-rooted environment as I had intended on making this into an application, but I imagine that if I can't touch or push these files from an adb shell then I won't be able to from the application space either.

It's frustrating not to be able to edit the filesystem of my own phone, I'll be rooting if this is just a permissions problem and not an issue of a non-writable filesystem. Perhaps I could still make an application for rooted-only phones.. hrm..

Any thoughts on this?

/etc is an alias for /system/etc, and /system is a partition mounted as ro (you can confirm this yourself by running mount)

Ah, bugger. So this is hopeless (without modifying and then reflashing)?

Thanks very much.

you need to mount it read write,

mount -oremount,rw /dev/block/mtdblock3 /system

then it will be read/write

try adb remount. if it failes you need root sorry.

Hello, i have the same error and I have root. i have tried adb remount and the mount -oremount,rw /dev/block/mtdblock3 /system

still dotn work. I want to move a script to /

so i only have to type sh debian.sh

nvm I figured it out. i just put it on system and then just type sh debian.sh on the terminal and it works

what is the error message? saying it dont work doesnt provide enough info for us to help....

it says sh: cant open aw.sh

so i still have to put the path or cd to where the file is. Is there a way to make /system my home?

no you cant make system your home, system is system, home is home. you can make a symlink if you are familiar with linux - might want to read up about shell commands
