Temporary disable root SU - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi, I want to run application which does not run on rooted devices (it displays warning that my device is rooted).
I have found promising solution:
adb shell
su
mount -o remount,rw /system /system
mv /system/bin/su /system/bin/backupsu
mount -o remount,ro /system /system
exit
Click to expand...
Click to collapse
but I get error on mv command that there is no such su file (even though su command is available in shell):
mv: bad '/system/bin/su': No such file or directory
Click to expand...
Click to collapse
Where is my su command located in file system?

Found it with command:
type su
Click to expand...
Click to collapse
its located
/sbin/su

{Behold 2 }[How-to] Root for App's working with Persistent root

First off, I want to say thanks to Kam187 & the Creators of asroot
Okay, Below is the Method I used for getting Root working for my app's.
Even though Shell is running as Root, any Call's made to su trigger's the white List Superuser.apk, So don't think your phone is wide open. G1's & MT3G Setup's are the same regard sh.
I'm not sure is the apk is counted as warez or not, if so I hope a Mod will remove the link to the Apk or let me know to Remove it...
Okay, File's Need to complete the Task is....
Try3 Placed in C:\SDK\tools> found here > File's attached below
SU for /system/bin found here > File's attached below
Superuser app control for our App's found Here > File's attached below
Next, Mount the SDCARD and place the SU file in the root of the sdcard like so ( /sdcard ). This is Important!!!
From here we do the Following.. ( Kam187 script the I edited ).
adb push try3 /data/local
adb shell chmod 0755 /data/local/try3
adb shell
/data/local/try3 /system/bin/sh
mount -o rw,remount /dev/st9 /system
chmod 04755 /system/bin/sh
cat /sdcard/su > /system/bin/su1
cat /sdcard/su > /system/bin/su
chmod 04755 /system/bin/su
su
cat /system/bin/playlogo > /system/bin/playlogo_real
/system/bin/chmod 0755 /system/bin/playlogo_real
echo "#!/system/bin/sh
/data/local/try3 /system/bin/sh
mount -o rw,remount /dev/st9 /system
chmod 04755 /system/bin/sh
cat /system/bin/su1 > /system/bin/su
chmod 04755 /system/bin/su
/system/bin/playlogo_real" > /system/bin/playlogo

Once Done, place the Superuser.apk in your SDK tools Directory.
Mine happens to look like this
C:\SDK\tools>
Click to expand...
Click to collapse
Once you have that Copied over, Open a Command prompt and CD to your sdk\tools directory and type the following.
adb install Superuser.apk
Click to expand...
Click to collapse
Once done, do a reboot of the Phone, Once boot up is complete open a Command Prompt ( or app that needs Root ).
For Command Prompt, type:
adb shell
Click to expand...
Click to collapse
su
Click to expand...
Click to collapse
If done correctly you will now see the deny or allow prompt on the Phone, or just open any app that needs root & you will see the same window.

Why 'adb remount' failed on a Rooted neuxs one

Hi,
I have rooted my Nexus one. I can do "'adb shell and then 'su' under the shell"
But on my MacOS Desktop, when I execute 'adb remount', it still said
$ adb remount
remount failed: Operation not permitted
Click to expand...
Click to collapse
Can anyone please help me resolve this?
Thank you.
[size=+4]DO *NOT* POST QUESTIONS IN THIS FORUM - only tips/info/etc.[/size]
Right at the top. Why does this have to be repeated on a daily basis?
Can you please move my thread to the right forum? I can't find a way to do it.
Anyhow, to answer you question... you "adb remount" is disabled in production releases... just rooting does not allow this.
You need a modified boot image where ro.secure=0 in default.props, instead of ro.secure=1. The ro.secure flag in the boot image indicates whether the root filesystem can be remounted as read/write... 0 indicated it can be... 1 indicated it cannot be.
If ro.secure=0, this is referred to as insecure boot.
Most custom ROMs have this by default... some rooted stock ROMs do not have this...
Will the Modified GRI40 (2.3.3 Gingerbread) ROM from this
http:// forum.xda-developers.com/showthread.php?t=968396
Does what I need? Thanks.
Or you can also use these commands to mount and unmount the system partition as writable:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
mount -o remount,ro /dev/block/mtdblock3 /system
Thank you. That seems to be an easier solution for me.
But after I did
$ adb shell
$ su
# mount -o remount,rw /dev/block/mtdblock3 /system
Click to expand...

I go to another shell and i did
adb push sqlite3 /system
failed to copy 'sqlite3' to '/system/sqlite3': Read-only file system
$ adb push sqlite3 /system/bin
failed to copy 'sqlite3' to '/system/bin/sqlite3': Permission denied
Click to expand...
Click to collapse
It still does not let me push 'sqlite3' to /system or /system/bin
That is what I need.
Thank you for any more pointers.

Don't try to combine adb commands with shell commands.
Copy/move/push the file to your sdcard first.
Then open a root shell, mount it as rw, then copy the file from your sdcard to the directory you want.
Thanks. but I get 'failed on '/sdcard/sqlite3' - Cross-device link'
$ su
# mount -o remount,rw /dev/block/mtdblock3 /system
# mv /sdcard/sqlite3 /system/
failed on '/sdcard/sqlite3' - Cross-device link
# ls -l /sdcard/sqlite3

I get the 'sqlite3' from SuperOneClickv1.7-ShortFuse.zip.
Wholly crap, don't use the mv command! Bad idea!!! mv does not move the data, it moves the hardlink to the data! Thank your lucky stars mv wouldn't let you do it.
Use cp instead. cp will actually copy the data to where you're going.
Thank you. But I don't have 'cp' in my adb shell.
# cp
cp: not found
# /system/bin/cp
/system/bin/cp: not found

I use 'cat' command to move to /system/bin
How do you have mv but not cp? Do you not have BusyBox installed?
No. I just need to search 'BusyBox' on Android market and install it? That is?

The cat command will work fine, no busybox needed: cat source_file > dest_file

Woah there partner. Cat shouldn't be used on binary files, only ascii files. While it might work fine, it is not the recommended practice and really should not be done.
OP, Yes, BusyBox can be installed from the market.

On standard Unix/Linux/etc. systems, cat works fine for binary files. It's only under DOS that cat or type shouldn't be used for binaries.
back in my ADB days.. itd say remount failed or w.e but i could still access my phone..
but i dont know.. ever since i switched to linux i stopped using ADB.. hahah

[Q] Cant cp or mv modules to dir "access denied"

I am trying to copy modules to /system/lib/modules/. I have rooted with Gingerbreak. I have superuser permissions both with adb and from terminal emulator. I have changed system to rw both from TE and with ADB. I used this command: mount -o remount,rw -t ext4 /dev/block/mmcblk0p3 system/ What am I doing wrong. System shows up as mounted rw when checking with cat /proc/mounts
Well, that basically works for me, but unless you did a typo on the "system/" only in the forums you got it slightly wrong.
su
mount -o remount,rw /dev/block/mmcblk0p3 /system
Click to expand...
Click to collapse
You don't need the "-t ext4" option.
Do I need busybox? It wasn't a typo. I get "permission denied" when I try to push the file. Not "access denied" as in the name. If it makes any difference. I have tried to cp from adb shell also. Same problem.
After installing busybox all went fine.

[solved]adb remount

Hello,
Has anyone gotten adb remount to work? I always get
remount failed: operation not permitted
Click to expand...
Click to collapse
I've also tried
Code:
mount -o remount,rw /dev/block/mmcblk0p4 /system
both from adb and in the terminal emulator but I get the same response
Trying to push anything to /system just results in
failed to copy '<file>' to '/system/<path>': Read-only file system
Click to expand...
Click to collapse
Any ideas?
Root?
You are rooted right? and didn't forget to "su" before those shell commands? because the shell command works fine for me, I remount system and changed the fonts
apparently I was just making it more complicated than it needs to be. You don't need to specify the mount point. Just use
mount -o remount,rw /system

Re-root failed

I´m trying to root my phone. It has been rooted before but something messed up and i dant have root anymoore.
I use this method
Code:
adb shell
/preinstall/dosu
/bin/mount -o remount,rw /system
cp /preinstall/su /system/bin/
chmod 6755 /system/bin/su
PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk
When i write
Code:
/bin/mount -o remount,rw /system
i get
Code:
/bin/mount: not found
if i check with Astro the file seems to be there.
Anyone know how to solve this?

Did you solved this problem yet?
You might try:
/system/bin/mount -o remount,rw /system
The /bin partition is osh, perhaps you remade this in some way that adb can not read/execute it?
