I just installed Android Q and was trying to mount the filesystem as RW in Android Terminal.
When I run:
su
mount -o remount,rw /system
I get an error that says '/dev/block/sda33' is read-only
I tried an app from the Play Store called "Mount /system RO/RW" but it didn't make a difference
I was just wondering if there is a solution yet for this?
Same issue, have not been able to rectify it.

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
So I'm totally unable to do anything to my /system in CWM via ADB.
Code:
> adb remount
remount failed: Operation not permitted
> adb push item.apk /system/app/item.apk
Failed: Permission denied
adb shell
$: su
Segmentation fault
$: rootsh
~# mount /system
mount: mounting /dev/block/mmcblk0p9 on /system failed: Device or resource busy
~# su
# mount /system
mount: mounting /dev/block/mmcblk0p9 on /system failed: Device or resource busy
# mount /system/app
can't find /system/app in /etc/fstab/
Pressing "unmount /system" in CWM results in "Error unmounting /system!" message. I tried pressing "Fix Permissions" but it didn't help. The only thing it did was that "su" results in "Segmentation fault" instead of "Permission denied". I just flashed my Lite'nin ROM again but it didn't fix anything.
I do have root access in normal OS so I can probably do some stuff in terminal emulator. But why is /system busy all the time?
try this:
adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p9

Thanks. That apparently mounted the /system but adb was still unable to push the files there. Maybe that is because "su" is still not working, only "rootsh". So I moved the file to my sdcard and then moved it to /system in shell.

since you are using a Secured Kernel(probably the CF-Root with CWM), you have to push the files to /sdcard
and then copy the files from the sdcard to the /system directory.
you can only push files with adb directly to the /system directory, when you are using an insecured kernel.

Oh. Thanks for the info, that cleared things up! I thought you only need to have a custom recovery in order to push with adb but apparently it's about the kernel.

this not working for me ,still can't mount the system i can't rm9 at ADB at all please help me !
Can anyone give me the command to mount /system/app as rw I screwed up something in there and can't seem to figure out how to mount it correctly so I can fix it via ADB
***Edit****
I was able to figure it out. The command was:
mount -o remount,rw /system
Is there some kind of trick to mounting system as rw so adaway can modify the hosts file. I have cm10 on here ATM
Did you try something like 'adb shell mount -o remount,rw /' ?
HTH
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!
