I'm sure this has been addressed but a search wouldn't located it. I had this woman bring a phone in and ask me to get this spy app to work on her son's phone, it has to be written on the /system. She paid someone on Craigslist to root it. I'm able to get the # in terminal emulator, and s-off is there but I'm still unable to write to /system. Even once mounting it through Clock workMod. The phone is running cm7 by the way. Any ideas on how to make the /system writable.

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

You *CAN'T* modify the / filesystem. It is part of your BOOT partition, which CANNOT be remounted rw. You would have to read, modify, and write the boot partition.

Maybe you're typing it in too literally. It should actually read like this:
mount -o remount,rw /dev/block/mtdblock3 /system
There was a typo with -oremount, there should be a space after -o.
Hope that helps.
PS. That command worked for me on a device where everything else failed.

actually, / can be mounted rw, but changes are lost on reboot

I would recommended not posting in the g1 section. The Asus forums would be a lot more helpful.

Download EStrong File Manager and within the settings of it, enable mounting of the system as read/write.
Or, download Terminal Emulator and type this in:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
Or, try typing this in terminal/cmd:
Code:
adb remount
Or, if you plan on doing it all from recovery you could do:
Code:
adb shell "mount system"
and then you could do it all from there.
Next time, please post in the proper forum.
Read-Only /system... i just deleted the file, tich push should update/replace and then it worked... only had this bug when i was trying to modify Trebuchet.apk (homescreen)
Hi guys
Not being a linux expert, i'm stuck with the following problem..
i'm using a program who uses low level adb commands to write on the phone extSdCard...
problem: this extSdcard is seen as a readonly filesystem.
What has to be done to make this FS RW instaed of RO ?
This does not happen under windows where I can write to the extSd without problems
thks in advance for the tip
Sorry if this has been covered,but how would I go about pushing a file by using the phone only?Is that possible to do in a terminal?And if so what commands would be used.Thanks

all you'd need to do is go into a terminal, then su, mount with rw permissions, then cp file /path/to/destination
and how do I mount with permissions?that's what I was missing,thanks

Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Go to Market and search for SU file manager or check out http://www.androlib.com/android.application.com-protocol-su-fbs-jmwq.aspx
It's not free, but it's cheap, and has pretty much replaced all the file explorer/editor/utility-type apps I used to screw around with. For all intents and purposes, you can use it to do just about anything you'd otherwise need adb to do.
Sorry if this has already been asked. I tried searching and couldn't seem to find clear terminal commands. All of them either didn't seem to work, or were actually adb commands.
What are the exact commands for installing an app through terminal?
I'm trying to find the easiest commands to help a friend that needs to install an app on his phone. He doesn't have a data plan so he can't go into the market to install it, and isn't near the computer for adb.
I've used this command set before to install an app to system before:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cat /sdcard/'name-of-app'.apk > /system/app/'name-of-app'.apk
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
But that is a little to complicated for him, and would be especially hard to explain over the phone, because like I said, he has no data plan.
Now I've seen this command around here:
su
cd /sdcard
install 'name-of-app'.apk /system/app/'name-of-app'.apk
But I tried that on my phone before giving it to him and it didn't seem to work.
So what are the commands for installing an app through the terminal to either system or data?
Install the sdk...
adb install application.apk

You just have to copy the application to /system/app (cp command), /system/ has to be mounted first of course.

I personally hate the automounting CDROM image with HTC software. I know it's fairly common knowledge how to disable it but below are the commands for anyone that cares. Make sure android debugging is enabled and enter the applicable command in your computer's terminal. As with other /system edits, this will only stick if you have S-OFF. You may need your phone screen unlocked to accept the su prompt if you haven't already granted ADB root access.
Disable HTC Virtual CDROM:
Code:
adb shell su root -c "mount -o remount,rw /system /system; mv /system/etc/CDROM.ISO /system/etc/CDROM.ISO.bak; mount -o remount,ro /system /system"
Re-Enable HTC Virtual CDROM:
Code:
adb shell su root -c "mount -o remount,rw /system /system; mv /system/etc/CDROM.ISO.bak /system/etc/CDROM.ISO; mount -o remount,ro /system /system"
i didnt know
I didn't know either... thanks!:good:
Never even crossed my ind to remove that annoying "feature"
Cheers man

Nope, I'm in IT so I always rename and not delete for small files. Personal preference.
I had no idea. Thanks so much
Nice. So glad to get rid of that stupid thing. I wanted to do that before but couldn't find where the file was located. Worked great. Thanks alot!
Thanks, just used root explore, found the file, and just added .bak to it.
Put a bootable Linux rescue ISO in there :angel:
unfortunately, I can't find that file. it exist because the silly CD popups every time I plug my phone in, but the .iso isn't in system/etc. my phone seems to be slightly stupid when doing a search. Oh well. Good info to have. Thanks for posting the instructions. I appreciate it.
For some reason I have never been able to mount my system r/w through adb or terminal emulator. I'm not quite sure what I'm doing wrong since I've been doing it for years now. I imagine it has to do with root. I can use ES file explorer and modify system to my hearts content just not through adb or terminal emulator. I am on 7.1.1 Pure Nexus with ElementalX 1.08 and SuperSU with 2.79 binaries. I've tried to mount multiple different ways and all result in same error.
Code:
sailfish:/ # mount -o remount,rw /system
mount: '/dev/block/bootdevice/by-name/system_b'->'/system': Device or resource busy
Nvm found it. I guess it's same as Pixel C.
Code:
mount -o rw,remount /system

Same here but with Oneplus 3T.
I think its kind of encripted "new way" in Android 7.1.1
Also, if you check the magisk thread there is a way to use the mount remount command inside root browser

Nope just a different mount syntax not encrypted at all. I was kinda thinking same at first like a security feature or root keeping you from so you don't accidentally modifying system.
mount -o rw,remount /system
Instead of
mount -o remount,rw /system

Sadly I tried your new syntax, adb did some stuff, but it does not work either.
Anyway thank you very much, your solution almost got it.
