after the 1 click root - not able to mount some directories in root explorer?

I used the post to install the one click root for the samsung epic 4g (sprint), and it appears to have worked. However - after entering root explorer, only some of the directories allow me to edit files. I click the remount as r/w button but nothing happens. Any thoughts?

Are you sure you granted root permissions to root explorer when it first ran? Run the superuser app from the app drawer and see if root explorer is on the list of apps that are allowed root permission.
I just tried v2.17.2 and it works fine. I tried changing the permissions on /system/xbin/busybox, it said filesystem mounted ro, then I press the mount rw button and redid the permission change, this time it worked no problem.

Thanks for your response-
yes, when i ran root explorer it asked if i wanted to grant superuser and i said yes. some folders allow it to remount, but - say the /system/bin folder - it doesnt allow it at all.

for further background, i used the automated instructions here for my root:
http://forum.xda-developers.com/showthread.php?t=1342728
i did option A like 5 times and also did option C (as i have EK02).
When opening root explorer it tells me that i have super user permissions. one thing to note- if i go to /system/xbin, i do not see a busybox directory. is there something else i should be installing?
in fact, i cant mount anything under the system directory or sub directories, but above that, i was able to change to r/w mode. i could also mount the /vendor directory right beside the /system directory...

If you were able to remount "/" as r/w then the problem isn't with root. That is basicly an "I'm a little bit pregnant situation" Either you are or you aren't.
Now if you weren't able to get root in the first place, then I'd look at the root.
As to busybox, there is no directory. There should be a file /system/xbin/busybox Also there should be a bunch of symlinks from various apps it supports to busybox.

I see - yea i did validate that busybox is not allowing for a mount or any type of change on that file/directory including busybox but the file is present. any suggestions on what else may be locking down this system directory?

I don't know if root file explorer is implemented it's own concept of ro/rw to protect you from making mistakes or it is using the system facilities. If it is using the system facilities, then once you remount /system as rw, then everything under /system is automatically rw. It is all the same partition.
I would try it from "adb shell" (do not type $ or # symbols)
Code:
$ su
# mount -o remount,rw /system /system
# cd /system/xbin
# chmod 755 busybox
If it lets you do that with no errors, then you have remounted /system/xbin as rw and the problem is with root file explorer. For that, you'd have to check with them or someone more well-versed in why that might be failing.

i appreciate your help
I went off googling the adb stuff/installed it and java's jdk stuff. then figured out how to run that adb shell stuff and validated that it worked (permissions were changed in places that this app didnt allow). knowing that the problem is actually with root explorer helps a ton.. as I just assumed it was working

[Q] Acer A100 on ICS and Rooted but unable to rename files

Hello, I was recently able to upate my A100 to ICS. I followed the root instructions in the developer section and it worked great. Both Titanium Backup and Superuser say I'm rooted but I can't move/rename the wpa_supplicant file. I really need to be able to use ad hoc to tether to my phone. Did I do something wrong in rooting my tablet? Any help would be much appreciated.
Thanks.

You need to mount system as r/w. Which file manager are you using?

I personaly used Root Explorer, its free and it has a friendly little buttong that has R/o R/W which allows you to read only to read and write

I redid the root and reinstalled Superuser, Root Browser, Titanium and Terminal...they all I'm rooted but when I try to move or rename the wpa_supplicant file it says failed. When I try to mount on Terminal it says it can't because I don't have root. What's going on lol? Did I do something wrong or is my version of ICS incompatible with the rooting method? Please help...

I noticed the same problem with Root Browser. It is probably not using the standard /system/bin/mount or /system/xbin/mount. Also it may be ZeroNulls mount script not taking in account for all possible mount scenarios. You could try my mount script in this thread forum.xda-developers.com/showthread.php?t=1512787 and replace your /system/bin/mount and /system/xbin/mount.
If you are sure it's rooted then remounting from a terminal will work. Are you typing su before trying to remount?
If you are and it still doesn't work try this instead
Code:
$ su
# mount -o remount,rw /dev/block/mmcblk0p3 /system/
BTW root explorer is not free

Thanks for your help. I didn't know I had to type 'su' first lol. That worked...kinda. Because I have to retype that everytime I rename or move something. Is that some kind of bug in the script?

Yes that is a bug in the script. Using my mount script Root Browser is able to modify /system files.

Looks like the old wpa_supplicant file isn't working. I did a search but haven't found any yet that work. Has anyone been able to activate ad-hoc on their A100 with ICS?

Why not just click the "remount r/w" button in Root Explorer (navigate to /system, then click it)? From my experience, whenever another app can't mount /system by itself, Root Explorer always helps it outta trouble.

If Root Explorer doesn't remount, there's a good chance you aren't properly rooted. You can verify this by 1) flashing the latest SuperSU zip or 2) flash another ROM and see if things work.

I CAN mount/remount system as r/w and then r/o using root explorer and i also get a notificatioin that superuser granted to root explorer. But Metamorph still doesnt work. It worked on my previous version as said in 1st post so dont know what the problem is.
i guess its a app specific problem then?

Did the update change OS, by that I mean 4.2.2 to 4.3? Perhaps metamorph doesn't work properly with 4.3. Have you tried uninstalling it and reinstalling the app?
If all you are doing is changing softkey images, I am pretty sure AOKP has options to do that within the ROM

metamorph has not been updated lately and therefore has not been made compatible with 4.3+ hence why you receive the /system rw error . if you check busybox and run the script or manually thru terminal you can verify if /system is RW or not.

Assuming you have a similar problem, how exactly is it going? This thread is a bit 'outdated' now because OP had trouble with an app intended for earlier Android versions. Apparently he was trying to use Stericson's Metamorph on a wrong Android version, thus it wasn't able to mount system R/W...

Es file explorer issue ,

On my op3 , I get an error when I try to use it for root explorer
Any help will be appreciated.
Thanks .
I tried reinstall the app as well as super su.
No luck

is your phone rooted?

Same here. Use an older version of ES File Explorer. It works

Did the spyware scandal not put you off using es ?

I'm currently using Fx Explorer

Cool thanks! I just remembered, I used to use Total Commander as well. Giving that and Fx Explorer a try!

just like ghostofcain, I use fx (with plus package). Perfect for me (even if there could be more clouds available tho).

Solid Explorer is awesome, too!
Sent from my LG-D855 using XDA-Developers mobile app

the same exact issue i encounter with my nexus 6.. not allowing me to select the root option.. workaround is to use solid explorer

Here u go this works, u may have to re flash su if it does not work after reboot
Download terminal and then enter the following
Attention!!!!! May break Android pay
su
mount -o remount,rw /system
touch /sbin/su
touch /system/bin/su
touch /system/xbin/su
mount -o remount,ro /system
exit
reboot

Doesn't work on my device.
The rw remount command is accepted without error message; but when I input "touch /sbin/su", an error comes up which says that the file system is read-only.

Simply use another root explorer app for access to system files.

For future issues:
Magisk mirrors all relevant partitions under /sbin.
The path to the block device /system is (only for system_as_root devices!!)
Code:
/sbin/.magisk/block/system_root
and it's mounted under
Code:
/sbin/.magisk/mirror/system_root
If you want to mount /system as r/w, you need this command
Code:
mount -o rw,remount -t ext4 /sbin/.magisk/block/system_root /sbin/.magisk/mirror/system_root
