how do i move a file to /system/bin ?

i rooted my verizon galaxy tab and i can run Root apps, but i cant move a wpa_supplicant file to my /system/root using Astro.
Is this a root issue or do i need something better than Astro? I also tried OI file manager but it just says "cannot move file here".

By default, /system is (usually) mounted read-only. You probably need to remount it read-write.

Code:
adb remount /system
adb push [path-to-file] /system/bin
If remount doesn't work, try
Code:
adb shell mount -t yaffs2 -o rw,remount /dev/block/mtdblock3 /system

Mac Terminal system remount syntax

I have an Atrix on AT&T. Which means there's a bootloader encryption, and the carrier prevents non-market apk installations, which I have resolved since my phone is rooted and I have changed the boot animation already.
In order to do these things, I found Ghost Commander that would let me chmod my system directories...which is fine, but I feel kind of gimped that I can't do it on terminal.
Basically, what I want to be able to do is remount /system as rw using terminal.
This method doesn't work on both terminal and emulator on my phone. I have done:
Terminal:
Code:
sudo su
cd [sdk directory]
./adb devices
./adb shell
su
mount -o remount,rw -t ext3 /dev/block/mmcblk0p12 /system
and this is where I get stuck because I just get an Invalid argument error.
Here is some info about my sytem -
Usage: mount [-r] [-w] [-o options] [-t type] device directory
/dev/block/mmcblk0p12 /system ext3 ro,noatime,nodiratime, data=ordered 0 0
Been searching for the answers for a while now and tried all kinds of syntax, and now I'm here. What am I doing wrong? Thanks

Try:
mount -o remount,rw /system
The remount option automatically looks up the info for /system so you shouldn't have to bother with the details.

Hmm, I tried that thanks, and I still got 'Usage: mount [-r] [-w] [-o options] [-t type] device directory'

Hmm, I can't think of any reason that wouldn't work but it sounds like your phone is locked down pretty tight. Do you know if others have been able to remount /system?
What version of busybox do you have? Maybe you could try updating it. There are one or two free busybox updater apps on the market, if you can use them.

Have you tried just 'adb remount'?
Does the mount command require busybox? Do you have that properly installed?

That requires adbd itself to be run in root mode (this is different from being rooted on the phone) & you could do that only on insecure boot image. mount/unmount both happen to come from the busybox package. It would be hard to contemplate that Motorola actually changed that but nothing would stop them from. You could try updating the busybox utility onboard your phone. There is nothing with your usage of the command - it would work the same way on my Nexus S

I do have Busybox in /system/xbin. Thinking that maybe the xbin directory may need to have the rewrite permissions, I changed its permissions to 777 using the chmod command in phone Terminal. I did the remount command 'mount -o remount,rw -t ext3 /dev/block/mmcblk0p12 /system' in shell on the phone, and I THOUGHT I BRICKED! Haha, but it just turned off, and I rebooted to find that my button backlights were turned off...which I fixed with the brightness file.
Anyhow, I think I'll just use the chmod command because that seems to work. NeoA, I think you are right about the adbd to run in root mode, because I've seen discussions about that before.
Thanks for the feedback guys! At least I know I wasn't having syntax errors to say the least

So did it remount it as rw? The mount command was running before, just giving errors, but if it's running that should mean the permissions were ok.

try
Code:
busybox mount -o remount,rw /system

"mount: can't find /system/app in /proc/mounts"
but
Code:
busybox chmod 777 /system
is good enough for me, for now

Using chmod to change permissions won't actually give you rw access to the system partition since it won't change whether it's mounted as read-only or r/w. To be able to run the chmod command, the system must already have been mounted as r/w or you would have received a "Read-only file system" error. It must have gotten mounted as read/write when the remount command caused a reboot. You can see how /system is mounted by just typing "mount" in adb shell which will list all of the mounted partitions.

[Q] mount: Operation not permitted

Whenever i type:
adb shell "mount -o remount,rw /dev/block/stl9 /system"​
i get the error: mount: Operation not permitted
adb shell "su mount -o rw,remount /dev/block/stl6 /system"​
i get Permission Denied
can anyone tell me what to do??????

Try to get "shell root" with Superoneclick. Then try again.

Happens the same with me. I was adviced to flash the last fugumod (Which also speeds up your phone) but haven't had time to try.

Because fugumod has allready rooted shell. You can use superoneclick to gain temporal shell root. After a restart will be lost.

For the 1st, you are not root.
For the second, you should not put 2 commands in 1. Enter 1 command by 1.
Code:
adb shell
$ su
# mount -o remount,rw /dev/block/stl6 /system
or if you want to put 2 or more commands, add a ";" between each command :
Code:
adb shell "su; mount -o remount,rw /dev/block/stl6 /system"
but you will have to send CTRL+C as qtadb doesnt seem to like 2 commands in 1.

What if I'm root and still get the same error?

[Q] removing BT5 arm off xoom

Hey, I installed BT5 arm on the Motorola Xoom wifi and i would like to know how to completely remove it from my device. My device is rooted and i have tried to delete the whole BT5 file with astro file manager and absolute file manager but neither of them worked. I was wondering if anyone knows another way of doing it.

I tried deleting it with commands in terminal emulator but its a read only file. Wouldn't chmod help with that? If so how would i use it?

Go read the backtrack 5 thread. There is a link on how to remove it. That really should be the first thing you check before asking

ok thanks, ill do that the next time i have a problem

I couldn't find it. I think it might be a tiamat BT5 img and i have the remover tool but im not quite sure how to use it. I just flashed it like i would do with a rom but it says installation failed. what would i do to fix that?

Common knowledge - system must be set to RW
Here is an alternate route- manually
How To:
ADB Shell Folder Removal - (we will use BT5 as an example)
++++++++++++++++++++++++++++
1. Connect Xoom to pc
2. Boot into recovery
3. Toggle to internal storage as /sdcard
4. mount /data
Enter adb shell via pc
(cd to file location) in this case BT5, is in the sdcard directory
Code:
Code:
cd /sdcard #
(once typed, you will be at.... /data/media prompt)
if after the above command and you are not at the /data/media prompt start over)
Code:
Code:
rm -r BT5
(BT5 is the stubborn Folder)
*Side note ... This works for any other stubborn folder that you want to delete as well...
USE AT YOU OWN RISK - MAKE SURE YOU DO A BACKUP FIRST
If this was helpful Hit The Thanks!

Come on now, lol Your device must be set to rw. Google can guide you.

I looked up on google how to mount system rw and thats where [email protected]:/ # mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system came from. then i tried rm -r BT5 after that and it was still denied. so i tried to
do chmod 777 BT5 to give all permissions and then when i tried to remove it again it was still denied.
I looked up the permissions of the file and its set to rwxrwxr-x. so chmod apparently didn't work

FP4 /e/os remounting /system ends in I/O error

I am trying to edit my gps.conf because of some accuracy problems but before I can push the new one I need to make the system rw first. When I try to remount it I get the following errors:
FP4:/ # su
FP4:/ # mount -o remount,rw /system
mount: '/system' not in /proc/mounts
FP4:/ # mount -o rw,remount /
mount: '/dev/block/dm-8'->'/': I/O error
When I try just remount the following happens:
C:\platform-tools>adb remount
Skipping /system for remount
Skipping /system_ext for remount
Skipping /product for remount
Skipping /vendor for remount
Skipping /odm for remount
remount failed
disabling verity ends in the error "Device is locked. Please unlock the device first" - Even though that is not the case.
I read somewhere that this is bad news but I am unsure. I cant even install busybox apk because it fails to write to system.
I have never tried to touch the system partition before so I am unsure how I killed something, if that is actually the case.
Do you guys have any idea how to fix this? Thank you!
