I've never used the command adb remount. Only adb shell and adb devices.

If I use adb shell it doesnt let me push files into certain folders. It says push is not a command... I'm trying to change my bootscreen

Hmm, I would help you if I could, but I don't know the steps for changing the boot screen. I haven't had the need for adb remount, sorry.

Just curious if you made sure usb debugging is on.

Kaik541 · Aug 15, 2010

I've also never used the adb remount, but as for your comment about pushing... push isn't ran from "adb shell"

you should be doing "adb push <file to push> /path/to/where/it/goes/<file>"

Of course this needs root and, in places where the NAND is mounted as read only, you must do the remount option with r/w

There are tons of guides on how to do this on our forum, but I'm too lazy to find them.

The thing is, I'm already rooted so I don't know why I can't do those commands. I will try to mount with "adb remount r/w"?

I get exactly the same thing but can't seem to find any help

I was having a similar issue. Maybe I can help.

First, I am already rooted and have busybox installed. Don't know if that matters, but can't hurt.

Here's what you can do:

Code:

C:\Program Files\android-sdk-windows\tools>adb shell
* daemon not running. starting it now *
* daemon started successfully *
$ mount
mount
rootfs / rootfs ro 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
/dev/block/stl6 /mnt/.lfs j4fs rw 0 0
tmpfs /sqlite_stmt_journals tmpfs rw,size=4096k 0 0
none /dev/cpuctl cgroup rw,cpu 0 0
[COLOR="Red"]/dev/block/stl9 /system rfs rw,vfat,llw,check=no,gid/uid/rwx,iocharset=utf8 0 0[/COLOR]
/dev/block/mmcblk0p2 /data rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,ioc
harset=utf8 0 0
/dev/block/stl10 /dbdata rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocha
rset=utf8 0 0
/dev/block/stl11 /cache rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iochar
set=utf8 0 0
/dev/block/stl3 /efs rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset
=utf8 0 0
/dev/block//vold/179:1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=
1015,fmask=0102,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,s
hortname=mixed,utf8,errors=remount-ro 0 0
$

At this point, we can see that /system is mounted at /dev/block/stl9. With that knowledge:

Code:

$ su
# mount -o remount,rw /dev/block/stl9 /system

Now your free to do whatever it is you were trying to do. When you're done, don't forget to :

Code:

# mount -o remount,ro /dev/block/stl9 /system

That should do it. Standard disclaimer, not responsible, blah,blah,blah...

How can I add these commands as aliases to the phone's shell?

Everything is fine until I get to
$ su
I get "Permission denied"

Hmm... anyone has any tips? Thanks!

slifer315 · Nov 30, 2010

when you type su into the command prompt, you should get a pop-up on your phone saying unknown is requesting superuser permissions and you need to allow it or you will get denied permission.

jvanja · Nov 30, 2010

Thanks! I passed that.. Now Im confused about whats the next step to push an apk into /system/app. I tried exiting from shell ("exit" twice until I saw C:\Program Files\android-sdk-windows\tools>) and then tried adb push.... but again I got No permission message ..
any advice?

Did you do the "mount -o remount,ro ..." before you exited the shell ? sounds like your still on Read-only .

-First thing copy the .apk app into the sdk tools folder.
-Then do the following

Code:

adb shell
su
mount -o remount,rw /dev/block/stl9 /system
exit
exit

-Now from your windows command prompt in sdk tools folder
adb push my_app.apk /system/app

-Once your finish
adb reboot

After the reboot your /system is returned to it's original read-only state.

Thats exactly what I did..:/ Does shell give you a confirm that you got the rw rights after doing:
mount -o remount,rw /dev/block/stl9 /system??

In my case it only responded with the same line below..

No it wont say anything. After you've done the remount,rw check your mount with "mount" in the shell. The /dev/block/stl9 /system line should read like this.

Code:

/dev/block/stl9 /system rfs [color=green]rw[/color],vfat,llw,check=no,gid/uid/rwx,iocharset=utf8 0 0

rather then

Code:

/dev/block/stl9 /system rfs [color=red]ro[/color],vfat,llw,check=no,gid/uid/rwx,iocharset=utf8 0 0
