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

[Q] Having trouble mounting \system in rw on BAMF 1.5

Hey guys,
Loaded BAMF 1.5 yesterday and have been enjoying the ROM thus far. However, I've been trying to push my custom widget.txt to the \system\customize\ folder so I can have my own power controls in the notifcation bar. I have tried the Mount rw/ro app from the Market, and have also tried mounting rw using adb (mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system).
Each time, when I use the command: adb push widget.txt /system/customize/ I get the error: failed to copy 'widget.txt' to '\system\customize\': Read-only file system
Where am I going wrong?

I'm pretty sure the TB is using EXT3, not YAFFS2.
Try
Code:
mount -o remount,rw -t ext3 /dev/block/mtdblock3 /system

Even easier, assuming you have busybox. busybox mount isn't as lame as the standard mount which is provided, so you don't have to tell it as much, it can figure things out on its own:
busybox mount -o remount,rw /system
busybox mount -o remount,ro /system
Click to expand...
Click to collapse

even easier.
sysrw
sysro
Doesn't anyone ever read the first post of my rom?

I'm an idiot. Thanks for the ext3 vs yaffs2 reminder.
I'll try busybox at some point also to check
And to Adrynalyne, apparently I didn't read the first post...my bad. Thanks for reading mine, though. I'll pay closer attention in the future.

INT2EXT

i want to use INT2EXT in cm9 i followed this tutorial
xpmode said:
INT2EXT+ INSTALLATION TUTORIAL
IF YOU ALREADY HAVE S2E, LINK2SD OR SIMILAR, YOU MUST REPARTITION SD CARD AND FACTORY WIPE
int2ext+ is a relatively new script that instead of making symbolic links(Link2SD) or moving certain partitions(S2E) to sd, extends your internal storage into your ext partition in sd, which means S2E's potential space saving and Link2SD's stability combined together and gives you something to brag about.
PREPARATIONS
Download the latest build of CyanogenMod 9.
Download the latest version of CronMod INT2EXT+ here.
Open CyanogenMod 9 zip.
Navigate to /system/etc/init.d
Open INT2EXT+ zip.
Navigate to /system/etc/init.d
Add the file called 40int2ext in the /system/etc/init.d directory in CM9 zip.
INSTALLATION
Go to recovery, do factory reset and advanced > partition sd card.
Select 1024M for ext(for some reason, I selected 4096 and it only read the first 1GB-ish) and 0M for swap.
Wait until it says Done and goes to menu.
Go to Mounts and Storage.
Select USB storage and connect your phone to your computer.
Copy your modified CM9 zip file to the root of your sd.
Select unmount.
Reflash ROM.
Reboot.
After reboot, go to settings > developer settings > root access and select Apps and ADB.
Go to your adb directory and do adb shell.
Type su.
Then do:
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
Reboot.
After reboot, reboot into recovery and flash gapps.zip normally.
Then go to Applications and enjoy your new, extended internal storage.

can someone help me how to do adb shell and go to adb directory

Use the directory that you used to root your device.

Err, now that's funny. To do adb shell, all you have to do is put in the command adb shell
Isn't that funny? xD
What the guide meant for adb directory is the place where the adb.exe file is kept.
So all you have to do is put in cmd:
adb shell
and while you're in shell you just put in those commands:
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
After that to close the terminal, type in:
exit
then adb reboot
Hope that helps =)

Hmmm, you don't need adb for this. Just use terminal emulator on your phone. It comes installed by default on CM9 roms. Or you can search play store for android terminal emulator. The app is by Jack Palevich
Code:
su
mount -rwo remount /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -ro remount /system
Then again, I don't really see why it is necessary to deny execute permissions to these scripts in first place. They are just empty shells - unless they have been modified.
I'm using int2ext4 right now and never really had to...
EDIT: If you want to reverse these changes then
Code:
su
mount -rwo remount /system
chmod -R 755 /system/etc/init.d
mount -ro remount /system

As of link2sd it uses installrecovery.sh file in /system/etc to mount sd-ext partition. It then moves apps/data/dalvik-cache to sd-ext and places symlinks at the original locations.
Take a look here where i've explained why symlink based apps/scripts should not be used on HTC explorer.
Hit thanks if i helped!:good::good:

[Q] Mounting /system read-write fails under adb shell, CM11

Hi! My problem is that I want to mod /system/etc stuff. But problem is: I can't mount /system rw in adb shell!
I'm using CM11 20140622 Nightly
What i've tried:
- sysrw command(alias sysrw='mount -o remount,rw /system')
- by hand(mount -o remount,rw /dev/block/platform/msm_sdcc.1/by-name/system /system)
None of those commands produce output and they exit 0
- ES File Explorer and CM File Manager
I don't know how, but mounting rw in UI always works, but not over adb.
Can anyone tell me a solution how to mount /system rw successfully over shell?

There is actually and it's set to "Apps and ADB", but I might try out next nightly. It might doesn't have that problem anymore. Prolly some SELinux conflict or kernel blocks something

Now it works.
I think it was CM problem.

For posterity, I'm adding what worked for me on LolliKat (which is cm11) for doing this from the phone's console/shell: I had to use the command `/system/bin/mount` rather than just `mount`. Once that had been done once, the other methods would work fine until reboot. (I was doing this because somehow link2sd had lost its ability to "update mount scripts" and "integrate system app updates".
These all worked for me:
/system/bin/mount -o remount,rw /system
/system/bin/mount -o remount,rw -t yaffs2 /system
/system/bin/mount -o remount,rw -t yaffs2 /system /system
/system/bin/mount -o remount,rw -t yaffs2 /dev/block/mtdblock8 /system

Android P preview5 rooted, gain su,but i/o error after remount /vendor partition

Have flash my new pixel 2 with latest android P preview5, rooted with twrp and magisk 16.04, I can get su under adb shell
I can remount the system as rw but fail in /vendor, an mount: '/dev/block/dm-0'->'/vendor': I/O error is coming accross
130|walleye:/ $ su
walleye:/ # mount -o rw,remount -t auto /system
walleye:/ # mount -o rw,remount -t auto /vendor
mount: '/dev/block/dm-0'->'/vendor': I/O error
1|walleye:/ # cp /mnt/sdcard/xxxx.so /vendor/etc
cp: /vendor/etc/xxx.so: Read-only file system
I'm pretty sure this is working in a rooted pixel XL of android OREO,
copy the file in TWRP file manager can't work either, I can see the file is copied into the vendor in TWRP, but file gone away after reboot into system, any suggestion is pretty appreciated !

Have tried magisk 16.7, but in vain, system partition can be remounted as "RW", however not the case in /vendor,
any tool can help to remount a partition during runtime ?

I found disable AVB2.0 / dm-verity can do the trick, now I can remount /vendor partition without I/O error !

If i can ever get my Gf to stop playing with my pixel 2 ( she has an iphone ). Ill update from DP4>DP5 and see how far i get.

Im having no issues after the update.
- flashed DP5 with Deuces Script.
- Flashed Twrp 3.2.2
-Booted system to setup initially.
-Booted to twrp installed Magisk 16.7
-reboot system .
havent had an I/O error. rooted fine.

after unchecking Preserve AVB v2.0/dm-verity in app, Magisk needs to be reinstalled. Quoted from here:
in Magisk Manager, “Uninstall > Restore Images” to restore the images, check “Preserve AVB 2.0/dm-verity” box in Advanced Settings, then reinstall Magisk via the app.
