Remount rw - Epic 4G Q&A, Help & Troubleshooting

Runnin ee03. However need some input while using terminal. When at the SU prompt remount rw does not work says comand not found. Busybox issue maybe or was the command removed?

Superuser su binary

I've noticed that the su binary installed by superuser doesn't survive a reboot. Anyone else have this problem? Any fixes?

Same here. Have to re update after each reboot

same here, had to update the binary too
How do you update the su?
Launch superuser, go to settings and scroll to the bottom.

I've found 3 su:
/system/bin/jk-su (original from the oneclick/permanent)
/system/xbin/su (symlink to /sdx/su)
/sdx/su (superuser updates this one)
Superuser does not update /system/bin/jk-su so I decided to.
So far its working.

How did you update it yourself?
Here's what worked for me. Keep in mind I am rooted using oneclick 2.2.4 which comes with busybox and remount scripts.
1. Update the su binary using superuser.
2. Launch a terminal (I use better terminal emulator pro)
3. Run 'su' from the terminal
4. Mount system rw with 'remount rw'
5. Remove jk-su with 'rm /system/bin/jk-su'
6. Copy the su binary superuser installed with 'cp /sdx/su /system/bin/jk-su'
7. Reboot and it should survive.
Notes:
Do not include single quotes when running the commands.
I'm paranoid about permissions so as root in terminal I ran:
chown root.shell /system/bin/jk-su
chmod 755 /system/bin/jk-su
To match the permissions of the removed jk-su. I'm not sure if this was necessary.
I haven't tested using adb yet so I don't know the steps.
Sent from my SPH-D700 using XDA App
Code:
#cp /sdx/su /system/bin/jk-su
cp: not found
the last part does not work (i have the same root method)
i have to re-root the phone when i get home today. but i will try to move the updated binary with root explorer instead of the command line.
Replace 'cp' with 'busybox cp'.

I have this exact same problem on my Samsung Moment (have to update SU every reboot).
The directory structure seem a bit different. For example, there's no /system/bin/jk-su (in fact, if I find / -name 'jk-su' I get no results at all).
I am poking around the directory structure trying to figure out where to find the source and destination su files that I'm going to have to overwrite and I can't seem to figure which is which. Does anyone have any idea how to do the functional equivalent of dangdang's post on a Moment?
Thanks!

It was the most relevant post after doing a search. Forum etiquette blows my mind. I can only imagine how much "use the search feature!" I'd have gotten if I'd have made a new post about this. Oh well, I tried.

most likely SU is built into your kernel and short of rebuilding or repacking your kernel you cant update it..

[Q] Rooting Help

I apologize if this is already answered somewhere. I searched everywhere and could not find anything, but I might be using the wrong wording.
Anyways I am attempting to root my G2. I have managed to get adb onto the computer and it recognizes my phone. However, the next step in the wiki says to:
ON YOUR PC: Unzip the gfree_temp-root.zip files to a folder. From a cmd window or terminal, navigate to that folder and execute these commands:
$ adb push su /sdcard/su
$ adb push Superuser.apk /sdcard/Superuser.apk
$ adb push rage /data/local/tmp/rage
$ adb push busybox /data/local/tmp/busybox
$ adb push root /data/local/tmp/root
$ adb shell chmod 0755 /data/local/tmp/*​
However, it gives me error messages such as 'adb' is not recognized. I'm sure I am missing stupid but I cannot figure it out. Thanks in advance.
Just use visionary, it is much easier. Click temp root and when it is done perm root

I don't trust visionary. I want to go about this the safest way which is the gfree method.

Make sure that the adb (and other stuff tha got installed) is in your PATH environment, or cd to that diectory and work from there.

I checked the path a few times because I thought that was the problem. However, it all looks good. I'm going to try on another computer tonight and see if that helps.
Did you make sure that all the necessary drivers were installed?
When you type 'ADB Devices' does it show your phone?
I used visionary and terminal emulator and haven't had any problems at all.

Yes it shows my phone when I type 'ADB Devices' That's what's causing my confusion. I've reinstalled all the drivers that are needed. From what I am seeing it SHOULD work.

[Q] ADB PUSH : Permission Denied (AlphaRevX Rooted)

Hi Guys,
I have rooted my Wildfire with AlphaRevX long time back and i tried many different ROMs.
Currently i have installed JokerDroid4.2 ROM.
When i start adb shell its going to normal user($) but not root(#) and when i type su in the shell its going to root(#).
So, when i want to push files to /system/app using adb push its throwing exception of permission denied.
I have seen many threads regarding this problem but couldnot find proper answer to my problem.
Workaround im using is pusing my files to /data/local and after getting root access using adb shell and su im moving it to /system/app
(OfCourse throughout the process /system is mounted as re-write)
Please solve my problem..
EDIT : I allowed the superuser to give permission to adb shell when i typed su command but when i use adb push its not asking me for permission from superuser.
Thanks,
Sandeep
You need to set permision /rw ,to system folder via root explore,then do adb push

Have you already tried "adb remount"?

This should indeed solve all your problems. Just type that command, wait for the "remount succeeded" notification and than try to write in your system folders.
The reason is that your /system is not mounted as read/write (r/w) when you boot your phone, but as read-only (r/o). So afther the remount command /systemfiles will stay r/w, but when you reboot your phone, it will return r/o again.

How do i run it with root?
if i write sudo adb <command> (example)
it's says sudo: adb no such command
Run the command su first, it'll ask you for your root password (if you set it up) and root persists until you exit
Sent from my R800x using XDA App
su + adb command (su adb push)
not works :|
ok
i got SUPERUSER PERMISSION
i type
adb shell
then
su
and then it asked for allow or deny i press allow
no effects yet
Just double checking, are you running as root on ubuntu?
Sent from my R800x using XDA App
just type su on it's own and hit enter, then adb commands on a separate line (after entering linux root password, obviously)
also (i'm not sure how much this will affect it) try running chmod on adb...
Happened to me, make sure your SD card isn't mounted while your using adb

[Q] CM9. can't mount /system rw

Whenever I try and mount system as writable I get
Mount: operation not permitted
The error occurs whether I use adb or terminal.
Sorry! Realized after posting I'd gone into the wrong forum! Could a mod move it please? Or delete it and I'll make a new one?
Maybe try to download the ICS rooting.zip and run the macro using fastboot.
Open up terminal emulator and type:
su
mount -o remount,rw / system

This won't work on the a100. You still need the mempodroid exploit.
Works on mine. It's only a small price to pay to have the CM9 goodness on my tablet and it's R/W until next reboot.

This method doesn't work on my tablet.
Isn' there any other method to acquire r/w?

Either of the ICS root methods in the dev section should fix it

You might try "busybox" after the su and before the mount command, e.g.: 'busybox mount -o remount,rw /system'
Busybox knows about these things.
AZBOLIVE
just type in "su" enter it then type commands as normal.
your permissions wont let you at present,
letting the system know to run su works good.
hope it helps!
