I'm just having root from Magisk 13 on B25. I used ES File Explorer to convert some app into system app but /system doesn't give me rw permission. I keep change back to RO on my root explorer.
I diid terminal command and have this
mount -o remount,rw /system
mount: '/dev/block/bootdevice/by-name/system'->'/system': Device or resource busy
Click to expand...
Click to collapse
and this
mount | grep \system
/dev/block/sde13 on /system type ext4 (ro,seclabel,relatime,discard,data=ordered)
/dev/block/loop0 on /system/etc/hosts type ext4 (rw,seclabel,relatime,data=ordered)
Click to expand...

I feel like the security doesn't let me change permission for system somehow.
Thanks in advanced!
NVm, i solved the issue. I haven't disable the write protection. I guess i need to do it after upgrade android.

I'v just rooted my Tab, I don't know if I'm losing the plot but I can't figure out how to write to the system partition? I can't find any apps that will work (for free) and "adb remount" doesn't work. "remount failed: Operation not permitted"
Am I missing something?

adb remount doesn't work because /default.prop needs ro.secure set to 0 (not 1). This can't be changed easily without modifying the boot.img.
However, you can remount /system as a r/w filesystem using ADB by opening a shell and:
Code:
su
mount -o rw,remount -t ext3 /dev/block/mmcblk0p1 /system
or
Code:
su
mount -o rw,remount -t ext3 /dev/mtdblock3 /system

Thanks, so which should I actually use, the former or the latter?
I've personally used the first command, but I saw the second one on another thread and it seems to work as well.
To be honest, I think it's ignoring the parameter anyway.

Hello,
Has anyone gotten adb remount to work? I always get
remount failed: operation not permitted
Click to expand...
Click to collapse
I've also tried
Code:
mount -o remount,rw /dev/block/mmcblk0p4 /system
both from adb and in the terminal emulator but I get the same response
Trying to push anything to /system just results in
failed to copy '<file>' to '/system/<path>': Read-only file system

Any ideas?
Root?
You are rooted right? and didn't forget to "su" before those shell commands? because the shell command works fine for me, I remount system and changed the fonts
apparently I was just making it more complicated than it needs to be. You don't need to specify the mount point. Just use
mount -o remount,rw /system
I'm rooted via the standard root, with CWM installed.
When I attempt to mount /system as read-write with mount -o rw,remount /dev/block/system /system, about 10 seconds later it remounts as -ro.
This means I can't change anything on there, is anyone else having this issue and is there a fix?

I had a similar problem once and I fixed it by restoring an old nandroid backup, I was never able to figure out what caused it.
I had the same issue when I installed the ota2 update, then tried to reroot. I think I was able to change permissions by installing, then opening superuser app.
Im on OTA1.
Hello,
I've got the same problem. With the following programs i have read/write access to /system only for seconds:
Esexplorer, file manager hd, root explorer, total commander , especially: adb shell
Strange thing: i have no problems with permissons when using x-plore or titanium backup.
(Currently OTA2)
Installing superuser again does not fix anything.
I have the same problem here (OTA2) :-/
A workaround I found is to chain the remount-command with the command you want to execute on /system:
Code:
$ su
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p3 /system && cp /sdcard/Download/kernel_modules/cifs.ko /system/lib/modules/
# ls /system/lib/modules/
bcm4329.ko
cifs.ko
scsi_wait_scan.ko
Brilliant!

Remount /flex partition as r/w using adb. Use these commands in cmd :
Code:
adb shell
Code:
su
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock14 /flex
Now use root explorer and delete the apk's from the /flex/app folder. Then wipe dalvik-cache in CWM Recovery.

/Flex is deodexed. There is no odex file in /fex.
