Hi to all. I'm Abe Wayer.
I'm dreaming to start changing at first my own mobile OS end maybe going to develop a day.
Today it's just all the afternoon that i google....
I became root, I partitioned my sd and installing sdk & adb tools in a couple of days.
something goes quickly something not.
I have a galaxy ace with 2.3.6
I thought to start my develop time using adb.
first at all adb push.
So i made:
adb push test.txt /sdcard/test.txt
And i have: permission denied
I googled a lot and nothing worked:
Debug usb is on.
I umounted sdcard from /media (I use linux)
I've tried this as well:
mount -o remount , rw /dev/block/void/179:9 /sdcard
or
mount -r -w -o remount -t vfat /dev/block/void/179:9 /sdcard
But nothing work!
If im not able to push a file on a sd what i dream for?
My sdcard has two partition linux call them sdc1 & sdc2 first is 1500 Mib second 400
Thanks for your help
No Links too?
Please give me a hand!:crying:
Dont you have a guide ive not fought?
Please.....
News:
I've tried:
adb shel => su =>fdisk -l
and i've got the device name but if do:
# mount rw -o remount, rw -t fat32 /dev/stl10 /sdcard
I always have:
Usage: mount [-r] [-w] [-o options] [-t type] device directory
But is there somewhere on the web an adb shel man complete with examples?
How do i obtain -w permission on my sd card?
adb pull works so i can read....
if i try ls -l /sdcard i got: lrwxrwxrwx root root 2012-12-18 02:01 sdcard -> /mnt/sdcard
So root can write.
Have i to change owner to the card?
Or simply with adb i'd say i'm root?
have i to umount sdcard?
Please!

Wrong usage, correct usage (provided that the device is correct):
Code:
mount -o rw, remount -t fat32 /dev/stl10 /sdcard

Doesn't work as well.
my fdisk -l output is this:
# fdisk -l

255 heads, 63 sectors/track, 5 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/bml10 doesn't contain a valid partition table

You don't know that. This is just a symbolic link, not the volume itself. Do:
$ ls -l /mnt/sdcard
This will show you if the card is mounted properly. Also issue a "mount" command, no parameter. But you should not need to remount it, the sdcard is handled by magic via the vold daemon. As soon as you remove it from the GNU/Linux machine, vold will mount it in Android.

Do: $ ls -l /mnt/sdcard

With ls - /mnt I have:
# ls -l /mnt/
drwxr-xr-x root system 2012-12-18 02:01 obb
drwxr-xr-x root system 2012-12-19 14:27 asec
drwx------ root root 2012-12-18 02:01 secure
d--------- system system 2012-12-18 02:01 sdcard
So sdcar has not permissions?
mount about sdcard says
/dev/block/vold/179:9 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/block/vold/179:9 /mnt/secure/asec vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
tmpfs /mnt/sdcard/.android_secure tmpfs ro,relatime,size=0k,mode=000 0 0
It goes to be mounted rw but for some errors it came to be remounted ro?
I've proved with:
mount -o rw, remount -t vfat /dev/block/vold/179:9 /sdcard , And
mount -o rw, remount -t vfat /dev/block/vold/179:9 /mnt/sdcard
but the answer's always:
Usage: mount [-r] [-w] [-o options] [-t type] device directory
any ideas?
/dev/block/vold/179:9 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,g id=1015,fmask=0702,dmask=0702,allow_utime=0020,cod epage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

Your sdcard is mounted just fine, no need to try to change anything there. Don't confuse the sdcard with its mount point, different things.
Make sure you've got read access to your test file, and push it to some place you know you are allowed to write. And use the full path /mnt/sdcard/file.name just to be sure.
Also, again, do a "ls - l /mnt/sdcard" to see its really there.
I had the same problem when I didn't root correctly, check if you have root correctly by using a root app. (like root checker or root explorer)
I converted my card to ext4 and need to change the default mount options. Right now they are:
Code:
/dev/block/vold/179:33 /mnt/media_rw/sdcard1 ext4 rw,dirsync,context=u:object_r:sdcard_external:s0,nosuid,nodev,noexec,noatime 0 0
/dev/fuse /storage/sdcard1 fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
But I need to replace it with
Code:
/dev/block/vold/179:33 /storage/sdcard1 ext4 rw,noatime,nosuid,nodev wait
So far, everything I tried failed:
- Editing fstab.qcom is useless because it is being recreated at each boot.
- adding a umount/mount init script
Code:
#!/system/bin/sh
VOLD="$(mount | grep -E -o -m 1 ".{0,0}179:.{0,2}")"
sleep 8
su
umount /storage/sdcard1
umount /mnt/media_rw/sdcard1
mount -rw -t ext4 -o noatime,nosuid,nodev /dev/block/vold/$VOLD /storage/sdcard1
is also useless, because although it works, it only kicks in AFTER the system is already on the desktop, which is too late.
This is all on Android 4.3.1 (but it's the same story with 4.4)
Why I want to do it?
Because although ext4 sdcard is mounted fine with read and write, the system does not see it as external anymore. As a result, many, many apps just won't work claiming there is no sdcard in the system. Even DiskUsage app does not see it.
I suppose this is because it is mounted either with FUSE or remounted directly as ext4 too late (after the system completed boot).
Any ideas?
Hi,
My device is on 4.4.4:
I did the following as root
mount -o bind /system/test /sdcard/test
As root user, command mount returns the following
Code:
/dev/block/mmcblk0p12 /storage/sdcard0/test ext4 ro,seclabel,relatime,user_xattr,barrier=1,data=ordered 0 0
However, a normal user do not see the mount points being applied at all.
i.e. doing mount as a normal user does not return
Code:
/dev/block/mmcblk0p12 /storage/sdcard0/test ext4 ro,seclabel,relatime,user_xattr,barrier=1,data=ordered 0 0
How to make it such that normal user would see the mount options executed by root?
Edited:
I used an app called Folder Mount (requires root)
doing mount it returns the following for both normal user and root user:
Code:
/dev/block/mmcblk0p12 /mnt/media_rw/sdcard0/UCDownloads/cache/com.UCMobile.intl/httpCache ext4 ro,seclabel,noatime,nodiratime,user_xattr,barrier=1,data=ordered 0 0
So it looks like mounting with this app does propagate the mount options to also the normal user and not just root user. How do I achieve this?
Edited 2:
Another observation:
Running the exact same command
mount -o bind /system/test /sdcard/test
on another device (4.4.4) works. Now this looks like a device specific issue (but still, folder mount works on the original device). I would really appreciate it if someone know a little about what could possibly be the reason here and share it here.
Thank you.
I have a second partition on my SDCARD at /dev/block/mmcblk1p2, all I want to do is ensure that it is always mounted as /storage/sdcard0/mount seems simple I can do it in 5 second on Linux, on Android, it seems impossible I can try to add a hack, but that is lost every-time I update the ROM. There has to be some simple way to do it, that I'm missing. The best I have is to load up a terminal emulated su to root and run: mount -t ext4 /dev/block/mmcblk1p2 /storage/sdcard0/mount
Now in theory, the following would work but for 2 things:
mkdir /storage/sdcard0/mount
su - root -c 'mount -t ext4 /dev/block/mmcblk1p2 /storage/sdcard0/mount'
But for the fact the Android's su does not understand -c so that is out. as well as the fact that non-root users (u0_a216 in my case) can not access /storage/sdcard0.
All I want is a simple way to ensure that this is always mounted where I want it when I need it, yet this simple task is nearly impossible it appears on Android, so why is that?
The issue here is that the fat32 partition does not support large files so I need a separate partition that does such as ext4, in reality if the external sdcard could just be ext4 there would be no issues, and it would be faster, but that is Android for you.
Any suggestions?
Thanks,
ERIC
Insert mount script to init.d folder...
via XDA Premium
Ok, I have this mostly working with juicessh and tasker now for now
I have 2 shell scripts:
mountDev.sh:
Code:
mkdir /storage/sdcard2
chmod 777 /storage/sdcard2
mount -t ext4 /dev/block/mmcblk1p2 /storage/sdcard2
umountDev.sh
Code:
umount /storage/sdcard2
rmdir /storage/sdcard2
In Tasker I have 2 tasks defined:
I'm using the JuiceSSH plugin to open a terminal to localhost I then execute:
To Mount:
Code:
su -l --shell=/system/bin/sh --command='cd /storage/sdcard0 ; sh ./mountDSev.sh ; exit' ; exit
To umount:
Code:
su -l --shell=/system/bin/sh --command='cd /storage/sdcard0 ; sh ./mountDSev.sh ; exit' ; exit
I then created 2 icons, 1 for each operation on the home screen. I also created a Device Boot event to automatically execute and mount the task.
This works, mostly, however even though it is root, sometimes I get errors such as /storage/ is readonly, which makes no sense since it could create the directory at boot, but can not remove the directory later on, since it is readonly. Its a minor thing currently, but annoying.
The benefit of this is it is easy to transfer between ROM images and devices without worrying about it being wiped out every-time I update. In theory it also works without init.d support being enabled. Down side is it you need Tasker and the JuiceSSH plug-in so it costs money.
Hope this helps others.

Hi guys! I've checked a bunch of threads for answers and to make sure I wasn't double posting, but if I am please direct me to the right place and I'll close this thread super quick!!
So I'm trying to mount /system as rw in order to delete an embedded application. BUT I keep getting stopped at every turn. I'm sure I'm missing something obvious, but any help would be super awesome.
- 1st try: Just mounting the system as rw -> mount: Operation not permitted
- 2nd try: Getting more information about system using grep and attempt to mount again -> mount: Operation not permitted
This is what I got so far (as root):
Code:
# mount -o rw,remount /system
mount -o rw,remount /system
mount: Operation not permitted
# mount | grep system
mount | grep system
/dev/block/dm-0 /system ext4 ro,seclabel,relatime,discard,data=ordered 0 0
# mount -o rw,remount /dev/block/dm-0 /system
mount -o rw,remount /dev/block/dm-0 /system
mount: Operation not permitted
Any thoughts on where I should go from here?
Oh for system information, I'm running 6.0.1.
