Hey,
for years I've been remounting /system read-write with the following call from a root shell:
Code:
mount -o remount,rw /system
With Android 7.1.2 and specifically the SuperMan ROM on my SGS7 edge, this no longer works:
Code:
mount -o remount,rw /system
mount: '/dev/block/platform/155a0000.ufs/by-name/SYSTEM'->'/system': Device or resource busy
A bit of searching on the web revealed that the following, however, does work:
Code:
mount -o rw,remount /system
Can someone figure out why the order would matter?
I find this especially curious because e.g. the Synapse app seems to use remount,rw as well, at least I see the same error when trying to use it to remount the `/system` partition.
Thanks for any insights!

Trying to push files from adb to my phone but it wont let me because its a read only system.
I've done adb shell mount -o rw,remount /dev/block/mtdblock3 /system but it does not work, I'm running windows 7 could this be a problem?
Make sure that USB Debugging is enabled on the phone.
Settings...Applications...Development
C:\Users\Jake\Desktop\android-sdk-windows\tools>adb shell mount -o rw,remount /d
ev/block/mtdblock3 /system
mount: mounting /dev/block/mtdblock3 on /system failed: Invalid argument
C:\Users\Jake\Desktop\android-sdk-windows\tools>
It is enabled.
Are you in recovery mode when you're trying this? Or booted regularly?
If you're in recovery mode you'd mount it like this:
mount -o rw /dev/block/mtdblock3 /system

follow my tutorial for ADB set-up. http://forum.xda-developers.com/showthread.php?p=6054534#post6054534
I noticed you dont have SDK in C:/ root....
or a simple command like this should mount it as read/write:
adb remount
its what i have been doing and seems to do the same thing with less commands, unless someone can point out the difference for me.
Otherwise, try
mount -o rw,remount /dev/block/mtd3 /system
That should do it. The /dev/block/mtdblock3 is only required in recovery.

I would also like to know the difference between the two commands:
adb remount
and
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

having the SDK in C:\ root is not a necessity. People do it because it is easy to do it that way.
Hello all,
I am trying to push a file to my system, however I do not seem to be able to mount my system partition.
When I try to execute the following command, I always get the error "Operation not permitted" :
Code:
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
My phone is rooted and my USB debugging is on !!
Anyone no what could cause this. It has always worked when I was still on 1.6 (rooted) and now it doesn't allow me access.
When I use Rootexplorer, I have R/W access, so root works.
Anyone has any tips or advise ?
Try...
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
Tried that, and get permission denied
Should have added, make sure your screens on on the phone and allow SuperUser access when you type su.
never mind, one sec
I'm stuck in Recovery and trying to push a file to /system to try to fix things, however I'm not able to mount it as read/write using adb
$ mount -o remount,rw /dev/stl12 /system
mount -o remount,rw /dev/stl12 /system
mount: Operation not permitted
su
Permission denied
Any solution?
Ok so the Rezound has the bootloader unlocked and rooted with 1click method.
Root Explorer, and Root Checker verify.
Going into adb I am trying to adb rm /system/app/".apk"
It doesnt work.
I tried adb remount and it is not letting me and says operation not permitted.
If I type in adb shell I get the $, then type in su and get #
Titanium Backup. More than worth the money. You can freeze, remove, and backup anything/everything.

Try ROM Toolbox. You can find it free in Market.
Code:
busybox mount -o rw,remount -t yaffs2 /dev/block/mmcblk029p /system
This Will Mount The System As "read/write" And Switch It To "ro" To Go Back To "read-only"

I would suggest to drop the extra bits that someone could mis-type and shorten this to
"busybox mount -o remount,rw /system"
It's worked for me and takes a little chance out of the equation. Just my opinion take it for what it's worth.
I Was In A Rush Yesterday That I Typed In The Wrong Code And Just Realized It Now When He Said It Didn't Work. It's All Fixed Thanks For The Suggestions Always Appreciated On My Posts Or Threads.
Hello everyone, my issue is when i try this, it works:
Code:
mount -o remount,rw /dev/block/stl6 /system
But, when i try this, it doesn't work:
Code:
mount -o remount,rw /dev/block/stl6 /system/media
So my question is if i want to set "rw" for only /system/media(not for other folders in the system folder) without using root explorer, how do i do that?
Any help would be appreciated.
Thanks
The read/write permissions here are set for mount points, not properties of individual folders so you can't set it that way.
