ADB question

I have read many posts about ADB push/remount permission issues, etc. But unfortunately I still have not figured out what's wrong with my situation. First of all, I don't have a micro SD card, so I have to push files directly to the phone memory.
I firstly tried "adb push" but seems it doesn't work for me
$ adb push email.apk /system/app
failed to copy 'email.apk' to '/system/app/email.apk': Read-only file system

Click to collapse
Then I searched online and people said you need to remount first. Then I got the infamous permission problem
$ adb remount
remount failed: Operation not permitted
Click to expand...
Click to collapse
Then I tried open shell first. no go
$ adb shell
$ mount -o remount rw system/app
mount: Operation not permitted
Click to expand...
Click to collapse
I searched more and found it can get su permission so to make things work. But when I hit "su(enter)" after open adb shell, I don't see the "#" showing up but still got an error message after waiting for a while
$ adb shell
$ su
Permission denied

Any one can please tell what's wrong with my operation? I rooted my G2x but didn't flash it. I installed the ROM manager and installed CWM but didn't proceed to reboot into recovery mode.

you need to look at your phone and allow superuser app to grant permission

su app? how should I set it? I didn't see anyone mentioned that. Do you care to give a bit more details? Thanks.

I think I figured out. I have to manually run the superuser app and let it say in active. Then when I type in "adb shell" the app on the handset will ask my permission. Thanks for the reminder.
Plus I am doing the following as the following that I read from another thread
adb shell
$ su
# mkdir /data/yourname
# chmod 777 /data/yourname
# exit
$ exit
adb push gps.conf /data/yourname
adb shell
$ su
# mount -o remount,rw /dev/block/mtdblock6 /system (copy biggrin.gif)
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system (copy biggrin.gif)
# mv /data/yourname/gps.conf /system/etc

Root and ADB

My Xoom is rooted and running tiamat 1.41.
I'm trying to push a file onto the xoom and having trouble with it.
I have the Android SDK installed.
When I type ADB DEVICES, it shows my xoom listed as a long string of letters and numbers.
I figured out I could get into the shell by using ADB -s ###### shell (where #### is the numbers/letters shown as the device).
If I type remount, i get permission denied.
If I try to push a file onto the Xoom, I get permission denied.
What am I missing here and how do I mount the Xoom so that I can push files onto the it?
Anyone know where the libflashplayer.so goes? I have the official flash installed and don't see it in /system/lib

you have to cd into the directory where adb is. most people put it right on the root of there C drive so in terminal type "cd c:\android-sdk-windows\platform-tools" without quotes then type "adb remount" and you should be mounted
if you need more help with adb check out this guide http://androidsamurai.com/forum/viewtopic.php?f=12&t=4&sid=b8c229b771793d03bb84efbcf562e55b

I have tools and platform-tools directories in my PATH so I can run them from any directory. Even running it from the directory containing the executable fails with 'remount failed - operation not permitted'

you could try uninstalling and reinstalling android sdk

What does running "getprop ro.secure" say? (in adb shell/terminal on the tablet)

You're not in insecure mode. I thought flashing that kernel would put you into insecure mode? Maybe you need to reflash?
If you still actually have a working su binary, copy the file somewhere writeable, then su to root, then copy it from there again to the location.

Need help with adb :\

Hey everyone!
Recently I've had problems with using the command "adb remount". I thought it was a kernel problem but it happened with both Trinity and
Elementalx kernel. I have installed the universal naked drivers 0.73 for my nexus 5. I think it is a root problem since nothing pops up on my phone
when entering "adb root". I have tried to retype it several times and it doesn't say "adb is already running as root" or something like that like it used
to. It keeps repeating "restarting adbd as root" whenever I type that command. Sorry if I'm not clear :/
Thanks everyone!

I personally prefer to run adb via recovery. Have you tried this?

I have also failed to use remount in android.
The solution is as rootsu suggests.
Boot to recovery and do
Adb shell mount /system
Or
Adb shell mount /data
Which ever partition you want to be changing

I don't think so. It's just easier.
With SlimKat and elementalx*
I have adb and apps set as root in slimkat although I doubt this is a requirement in non-AOSP roms that do not have this option. Need USB debugging on and the screen unlocked

Root user cannot 'remount'

Hi,
after a lots of hassle I finally accessed the root access into my Sony z2 tablet. But the Root Checker Basic app says
Sorry! Root access is not properly installed on this device.
Click to expand...
Click to collapse
I can still run
Code:
adb root
without error. And the
Code:
adb shell whoami
returns "root".
Still when I run
Code:
adb remount
it says
remount of /system failed; couldn't make block device /dev/block/platform/msm_sdcc.1/by-name/system writable: Permission denied
remount failed
Click to expand...

I need to remount the device because I want to move an APK to the "/system/priv-apps" folder.

Did you try remounting directly from an adb shell ?
mount -o remount,rw /system

Are you trying to mount as root ? (your shell prompt should start with # and not $). If not, use "su" command to get root and then try mounting again.
If remount fails even from a root shell, check your SELinux status with "getenforce" command.

Yes, I am trying to mount as root so that I can move an APK to "system/priv-apps". My shell prompt does start with #. I cannot use "su", it says "[-] Daemon is stop".
I checked SELinux status. It says "Enforcing", then I tried "adb shell setenforce 0" it says "setenforce: Couldn't set enforcing status to '0': Permission denied". :'(

Likely SELinux is preventing remount.
Are you still using the original software or a custom ROM ?

Original software (I gained the root access using KingRoot, tried everything else, didn't work)

I would either flash SuperSU with a custom recovery (assuming you can unlock the bootloader) or flash a third party ROM.

I tried recovering with custom ROM but failed. Here I asked a question for reference, but didn't find working solution.

The ADB driver does not care at all whether phone's Android is rooted or not. As you correctly stated one have to run adb root for ADB to gain root access device's Android.
I don't want to examine why adb root in your case doesn't work.
Anyways the following should be a workaround:
Code:
adb devices
adb shell "su -c 'mount -o remount,rw /system'"
...
