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.

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

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.

Hello Everyone,
I have recently rooted my phone again but am having an issue. I cannot do an adb remount becase it says that permission is denied. This is going to be due to the fact that when I adb shell it starts with a $ instead of #. If I do the following it will work so that I can push files and system files:
PHP:
adb shell //enter adb shell
su //activate superuser
mount -o rw,remount /dev/block/mmcblock1p21 /system //mounts the drive and allows read/write
exit //exit superuser
exit //exit shell
adb push xxxxxxxxxx.apk /system/xxxxxxxxx/ //push whatever file is needed
My question is why can I not just adb push or remount? Does anyone know how to make it so that I auto superuser when doing adb shell so i get # instead of $?
you should be able to just type adb remount and have the /system turned either RW or RO depending on what its changing from...
Have you granted superuser permissions to adb? It should pop up on the phone.
yes superuser works on the phone. I can access superuser and it will work but I have to do it manually.

I understand that it should allow it but its not. That is exactly what this post is for. If i do the commands list in the first window this is manually change it to RW and then after I finish I set it back to RO.

Right, but a superuser request will pop up when you use adb remount. Try it again and check the phone for it.
its not getting to that point. It is giving me an error on the command prompt. I have checked for it and the SU wasnt there
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 expand...
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

I've unlocked my phone via HTCDev, which to my understanding should give enough permissions and whatnot for adb to work on system files too.
I'm trying to push application to replace system application, I know the application works, I got both signed & unsigned versions of it but same thing with either one of them.
adb remount says "remount failed: operation not permitted" and adb push [file] /system/apps says "failed to copy '[file]' to '/system/apps/': read-only file system
--
What am I doing wrong, or do I really have to root the phone just to get one damn application replaced with modified one?
Bump
Have you rooted?

You need to have SU# access, which be definition needs root permissions. If you haven't already, use the all in one tool kit to flash clockwork and root that beech. Then when in ADB you enter SU and you will get a prompt like this #, indicating you have root privileges.
Update, I have rooted, stock rom still though
If I use adb shell, I get $, but writing "su" in shell gives me #
still, I've tried both the adb remount and in shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
the latter seems to work, but however still when I try to push something to /system/app it still says permission denied
edit:
not quite sure what I did, but i finally got SUCCESS from installing from shell
how did you install through the shell

"adb remount" requires you to have the "ro.secure = 0" line in /default.prop on your tablet.
You need adbd insecure from Chainfire or KK-Boot boot image.

Or you can use adb shell
Asuming your rooted, and mount -o rw, remount

Of course. (as long as you get it right: "mount -o remount,rw /system")
But the OP claimed that having to do that meant that ADB doesn't "fully work" because "adb remount" doesn't work. That requires ro.secure to be set to zero.
C:\Users\HieAnh>adb root
restarting adbd as root
C:\Users\HieAnh>adb remount
Not running as root. Try "adb root" first.

after i do :"adb root" to cmd,
then i get :"restarting adbd as root"
next i do :"adb remount"
but i get :"Not running as root. Try "adb root" first."
a big question for this problem
my phone is rooted, switch ro.secure=0, ro.debuggle=1
pls help me
What response do you get when you type su in shell?

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'"
...

You have to mount /data partitton as RW.
