Welcome to our AndroidForums, @darknight216 .

Can you tell us exactly what mount command you are using to try to remount /system in read-write mode and also include the output of a simple "mount" command, too?

Thanks!

i have try all the command in this post http://androidforums.com/threads/cant-mount-system-as-r-w.970540/ but everytime my terminal say read only file system.. i have alredy try root file explorer and other app like this but nothing.. i m italian and i buy my cellphone in a wind store so i want to remount the system for change boot animation and remove file host to make a new one and get playstore work again

Please provide the output of a simple mount command (or even better: mount | grep system).

Thanks .

Good as place as any to ask this. I have seen this symbol in command lines. What does it mean? I can't find it anywhere on my keyboard.

That's the vertical bar or pipe command/operation (see/try shift of the "\" character/key).

It's used to pipe / redirect the output from one command to another.

This is my output for grep /system..

u0_a188@hwSCL-Q:/ $ mount | grep /system

/dev/block/bootdevice/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0

And if I do a simple mount it mean this is read only system

Very similar to this:

I'm thinking there might be some sort of write protection employed here. However on an HTC device, it will mount r/w until reboot at least. Try maybe Kernel Aduitor to set SELinux to permissive. Probably a command for that though.

u0_a188@hwSCL-Q:/ $ mount | grep /system

/dev/block/bootdevice/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0

And if I do a simple mount it mean this is read only system

Okay, let's try this sequence then:

# mount | grep system
# mount -o remount,rw -t ext4 /dev/block/bootdevice/by-name/system /system
# mount | grep system​

Hopefully, this version of the mount command will work vs. the generic ones you saw and tried before and that the second "mount | grep system" will show "rw" instead of "ro".

u0_a188@hwSCL-Q:/ $ mount | grep system
/dev/block/bootdevice/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0
-t ext4 /dev/block/bootdevice/by-name/system /system <
mount: Operation not permitted
255|u0_a188@hwSCL-Q:/ $

I dont know if I copy all right but I m sure in the command console was right but it say operation not permitted

 

[scary alien]

Hmm, I can't tell from the above, but you did type (or paste) this command on a line all by itself?

mount -o remount,rw -t ext4 /dev/block/bootdevice/by-name/system /system​

Also, I don't see that you su'd to root since your prompt is still a "$". I.e., normally, you'd do this first:

$ su
#​

Notice how the prompt changes from "$" to a "#"?

Are you sure you're rooted?

 

[darknight216]

Yes I m sure I m rooted because all my app that need root work and my root checker is working

 

[scary alien]

Not sure what's going on here, @darknight216...

You tried this, too, right?:

mount -o remount,rw /system​

 

[darknight216]

Yeah but nothing... read only file system

Another very similar issue. @scary alien Maybe you can merge these.
