I thought I'd post this...even though I'm a noob...so that others can benefit if possible. If you're using the JRummy BusyBox installer, please be careful with the Advanced Install option. Here's why:
After rooting my phone I installed JRummy's BusyBox installer. First, after checking busybox.net for the latest stable install version, I did a full install without the symlink apps option selected. Then I did another full install with the symlink apps option checked. Finally, after reading through the entire list of available commands and what they did, I decided to do an advanced install. I selected "Remove Symlinks" for each of the busybox commands I wanted NOT to have available in Terminal Emulator.
Soon after the advanced installation, I noticed that Terminal Emulator wasn't working. Then I noticed that my WiFi connection wasn't working...specifically the part in which the phone attempts to lease an address using DHCP. After emailing the developer with my issue, I tried to re-install BusyBox manually based on a link he included in the reply. I could push the file to the phone using 'adb push' but when I tried to open a shell to run the install commands, I would get the following error: exec '/system/bin/sh' failed: No such file or directory (2) . Long story short, I had to re-flash the phone using Odin to fix it.
In the AFWall+ logs, around the time I ran the Advanced Install, there were a bunch of entries like this: ld_library_path=/vendor/lib:/system/lib busybox rm /system/xbin/strings exit. There may have been a -s after the 'rm' command and before the directory but I'm not completely sure. After I flashed the phone with Odin, I opened Root Explorer and took a look at the files under /system/bin/. I noticed that the commands that can be run without installing busybox...like ls, or ifconfig...were linked to 'toolbox'. /system/bin/sh was linked to mksh.
After more research and reading, I'm about 90% sure what happened. Here's an excerpt from the email I sent to the developer:
<snip>
Basically, the "Remove Symlinks" option in your app does either one of two things:
It removes the directories entirely
It removes the symlinks to busybox, but doesn't restore the original symlinks that were present before busybox was installed.

So if you're using this particular installer, please be careful with the Advanced Option.
Please help

Hello I installed BusyBox and I had same issue with WIFI also others for example after reboot of my tablet wholle setting is set to orignaly(language and everithing).How can put back everithing?Does exist some apps etc???Thank you.
OMG... i installed busybox with this app into /system/xbin on my dopo d7015 with advanced install... and then the problems started... 0 total internal size, wifi not acquiring ip with dhcp ... no factory restore could fix it. then i eventually learned that /system/bin/sh didn't exist when trying to adb shell. i've downloaded an sh binary and copied it, now i have valid internal total size, and android terminal works... but wifi won't even turn on now! like an idiot i didn't backup before i started playing with the tablet... i have no clue as to how to fix it! please someone help me!
With one version of this app, it said Busy box 1.20.x is not compatible for my phone. But busy box installer by Stericson does the job perfectly.

Let me first say that I have read every post I could find on this subject and tried them all with no success. I rooted my Aria using the Ubuntu Live CD so I could use Titanium backup and eventually try different roms. My phone is still using the stock rom. I then installed Titanium backup which reports "your system settings will prevent you from restoring applications. to correct this go to your phone's settings, then in "applications" and tick the "unknown sources" check box."
The unknown sources check box is of course not there because I have not been able to successfully run the code for allowing non-market apps.
From terminal in the Ubuntu Live CD with USB cable connected and set to charge only. I tried and got "remount failed: operation not permitted." at the adb remount step.
Linux Code:
sudo su
adb remount
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
echo "update secure set value = 1 where name = 'install_non_market_apps';"|sqlite3 ./settings.db
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
adb reboot
I downloaded the android-sdk_r07 and extracted it to my C drive. From a Windows command prompt, I changed to the sdk\tools folder. Adb devices sees the phone but adb remount fails with "remount failed: operation not permitted."
Windows Code:
adb remount
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
echo update secure set value = 1 where name = 'install_non_market_apps';|sqlite3 settings.db
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
I found a post from attn1 that I have not tried that said:
"Put your phone in recovery mode. Go to advanced>mount system and mount data. Follow steps in post #13 (using the windows or linux code above) in cmd screen and you'll be fine." I am not comfortable in trying this approach as there are not enough specific step details and I don't want brick my phone.
I would really appreciate the correct detailed steps to enable non-market apps using the supplied code either from Windows or the Ubuntu Live CD. Thank you in advance.
You are rooted, so boot into recovery and create a nandroid backup; if something goes wrong when pushing settings.db and you cannot boot, restore your nandroid backup. Then, as attn1 stated, perform the same steps you mention above, but while the phone is in recovery and you have mounted the system and data folders.

Thank you winsettr for your post. It looks like running the commands from recovery did indeed work. Titanium backup no longer reports the "your system settings will prevent you from restoring applications. To correct this go to your phone's settings, then in "applications" error.
However, I expected to see the settings\applications unknown sources check box check box and it is not there. I guess I will have to try side-loading an app to confirm that it will work.
I think that gui option would be part of the rom, a part that AT&T has removed... So yeah, see if side- loading works now.
Sent from my Liberty using XDA App
FYI, I am indeed able to side load now from an .apk copied to the sd card. However, I am not able to install from an internet link. Trying to do so generates a "your phone is not authorized" error message.
Until you get a custom rom running, I wouldn't worry too much. Sounds like you can get any app you want (just download internet apps to sd then install). There may be an additional setting in settings.db but that's beyond my knowledge...

I have wasted more than 3 days trying to figure out how to configure openvpn
on S2.
I tried the following roms:
Villainrom 1.4
Cognition S2 v1.07
Skyrom 1.0
Lite'ning Rom v1.5
and none of them seems to work.
I tried everything mentioned in :
http://forum.xda-developers.com/showthread.php?t=1115984&highlight=openvpn
http://forum.xda-developers.com/showthread.php?t=1074492&highlight=openvpn
but openvpn does not work.
I also own a HTC desire and configuration files work without a problem.
I tried manually installing openvpn as described in the posts but it does not work.
The problems are:
If I install openvpn manually as described in the threads above it does not connect to the openvpn server.
I installed openvpn from the market by selecting the folder for the binary
/system/xbin
and tried all the possibilities for path for ifconfig/route.
- /system/bin
- /system/xbin
- /system/xbin/bb
The default folder for ifconfig/route should be /system/bin (result from which ifconfig) and only that selection does not give the horrible
"FATAL: Linux ifconfig failed: could not execute external program".
but openvpn still does not work.
Any ideas ?
Hello,
I have the same problem, with same error
but I have successfully get connected to my vpn (vpntunnel.se) but its useless since the route doesnt use the vpn connection.
If anyone could help...
i have same problem too. some help would be good
Could this help?
I'd love to get this working too but I have not made any attempts yet so I'm monitoring this thread.
Searching for that exact error message on google led me to this thread which you may already have found.
In particular, even though it's about the galaxy i5800, the following comment may shed some light:
you may not use the pre-installed busybox from samsung (which is found in /sbin). It is a reduced version of busybox that does not include suitable ifconfig- and route-commands for openvpn. thus you have to install a full version of busybox... normally this is done, when you root your phone according to descriptions found in this forum.
you can alternatively install titanium backup (which installs its own busybox) and copy the "full" busybox from titanum backup to /system/xbin.

Alright, so after going nutts (several times) I solved this issue (several times) only to always find I dont really know what the error is. But then again, I know more about Geological disasters than I know about Android ...
Anyways, heres my solution which appears to work. However, it goes away once you reboot (easily fixed) and disappears completely after you update firmware - but I made shortcuts.
The thing is, that the original busybox is not installed where openvpn looks for it. Regardless of this, openvpn has no idea how to use ifconfig / route commands in /system/bin directory.
So this is what I do:
1) Install busybox (from the market, get ver 1.19) to /system/xbin
2) Install openvpn to /system/xbin and point ifconfig/route to /system/xbin/bb (during installation).
3) Link the new busybox to the /bb directory MANUALLY with these commands (customized to steps 1/2 - you can change them to your liking but dont forget to update step 3 as well):
ln -s /system/xbin/busybox /system/xbin/bb/ifconfig
ln -s /system/xbin/busybox /system/xbin/bb/route
Click to expand...
Click to collapse
What it does is place a busybox link to ifconfig and route in /bb directory.
Funny thing - Whenever I tried linking ifconfig/route to other places (like /system/xbin) it just didn't work. It made the tunnel, but tun0 int was always down (thats why it says "connect to as xx.xx.xx.xx" missing the tunnel internal IP - as in, no routing).
Challanges - when you soft reset, something dies. Not sure if its the busybox or the links. However, simply "reinstalling" busybox to /system/xbin solves it (its not really reinstalling, its just going into the busybox installer. Its only recreating links).
When you install an update/new cfw, everything dies. Reinstall busybox and re-enter the link commands.
Hope this helps, hope some android programmer tells me why it works this way. gluck.
Hi, I've been trying to move all my game data from my internal SD card to my larger external SD card with no joy.
I have used condi's AIO tool to install init.d support, which reported as successful, but when I follow obicom's instructions as listed in POST #43 of this thread http://forum.xda-developers.com/showthread.php?t=1490116&page=5
I repeatedly receive the message "Operation not permitted."
I have used both ADB Shell and Terminal Emulator with the same result.
I'm obviously doing something wrong as other people appear to have had success with these instructions, I just don't know what.
Here's what I've done: (on rooted ICS from condi's AIO tool)
Installed init'd support "successfully"
Moved all data from sdcard/Android/data over to sdcard2/game_data
In ADB Shell/Terminal Emu. entered the following line;
mount -o bind /sdcard2/game_data /sdcard/Android/data
and this is where I get the "Operation not permitted" message.
Any ideas?
Once you're in shell, before running the mount command, run the command 'su' first (without the quotes). Your prompt should change from $ to # and try running the mount command again.
Explained: In most Linux systems, unless the fstab has been specifically setup to do it with the user option, filesystems can only be mounted by root. In rooted versions of Android, the normal user can elevate into a root prompt with su, then allowing you to mount and unmount any filesystems.
Ahaaa
Awesome! Can't believe it was something so simple, thanks, and thanks for explaining the reason.
I must have somehow totally missed the "su" instruction in the other thread.
Half of my games work, the other just seem to need re-installing which is no big drama.
Again, thanks, it's much appreciated mate.

Hi, is there a way I can create a script (or the like) that would do this, and other similar directory changes, at boot?
At present I need to enter these manually each time the tablet starts, which isn't too much of a drama for me but when other people use it they end up downloading the data all over again when they start a game.
Thanks
There is an app available on Google Play called Script Manager (which can be used to create scripts to run at boot as su (which mount command require), which should do what you need. You'll need to use a plain text editor (I believe there is one included with Script Manager) to enter each of the mount command you want to run on a separate line. Then set the file to executable (chmod +x scriptname), and add it to Script Manager.
Note that I haven't used it in a while, so follow whatever instructions Script Manager gives you. They're probably more up to date.

I tried to upgrade the busybox with different manner (busybox, busybox installer, manual installation from xda), but no one works properly.

Can someone explain to me the good way to upgrade the busybox?
Thanks.

Hi,
As i said, i tried the different busybox installers and the installation was ok, but i each time, i lost the shell from adb.
That's just my problem.
So i just want to understand why the upgrade of the busybox broke the original archos busybox?
Moreover some application need to have other busybox installed.

Ahhh right, the quest for knowledge Your problem is as much to do with adb ( /sbin/adbd to be precise ) as it is to do with busybox, firstly you've probably wiped out the symlinks in /bin, especially /bin/sh which is the location that adbd on archos looks to run the when you do adb shell from your desktop. This is not the default location which just about every other android OEM adheares ,that is /system/bin/sh.
If you are going to upgrade the archos busybox be aware that a large number of symlinks back to /bin/busybox exist not only in /bin but also in /usr/bin /usr/sbin
Archos for reasons I still haven't fathomed, really went to town on restructuring and customized Android on the platform level.
A little tip if you've got more question, to save you bumping threads , which really does upset some folks round here... you'll probably get more more if you add more details, such as error messages etc. Saying " i lost the shell from adb." doesn't really help anyone who might be able to offer assistance. There about 10 different ways adb can fail to connect, Did the device disappear from the list or report as offline. or even come up with the message "- exec '/bin/sh' failed: No such file or directory (2) -".??
Hopefully that's helped.
Hi SirOrch,
i don't know why you loose your adb shell, but concerning busybox... the things on Archos tablets are like this:
Basically on a non rooted device we got a squashfs image mounted read only.
This image contains the stock busybox compiled by Archos (sharing system's uclibc) with limited functionality,
but containing enough tools to handle the daily job.
The path to this busybox is "hard-coded" as well. It's location is /bin which is the second entry in the path environment.
You might check that by typing printenv in your console.
The first entry should be /data/local/bin on your device.
So if you like to replace stock busybox with an advanced one, you should make sure that it will be installed to /data/local/bin.
Often there's no need to use all this apk Android Market stuff to get a proper busybox installation.
Sometimes it's little better to really understand what's happening under the hood.
Most busybox app's are statically linked, because with a static binary you don't have to take care of the device's libc or uclibc.
So you might easily extract on of the apk's or get one from xda-developers.
There are many floating around in the end.
If got one push it to /data/local/bin with adb.
You might need softlinks in this directory as well. This could be done by hand as well.
Anyway if you are a lazy person, who doesn't care about what's happening, go to the market install busybox.
Then check at /data/local/bin if it is there.
If it got installed elsewhere, some commands will still use stock busybox.
Extended commands might then use the installed one.
So check it out...
EDIT:
... aaaargh again simultaneous posting.

Hi gentlemen,
Thanks for your help and sorry to forget to give you the error message i had:
the message was : - exec '/bin/sh' failed: No such file or directory (2) -
After investigation i found my mistake:
- In manual mode, i forget to change the ownership of busybox to root in /bin.
- when i tried to use any application from the market, the busybox was well updated in /system/xbin but the application also delete the busybox in /bin and don't change the symlinks in /bin. That's explain why adb shell won't work.
Regards.

Hi
I've installed CM10.2 (last update) (http://forum.xda-developers.com/showthread.php?t=2499796) on my Archos 80G9. It also runs the SDE firmware from Archos (http://forum.xda-developers.com/showthread.php?t=1653566). So far, so good, it runs quite nicely, all things concerned. Here's a screenshot to the system info: https://www.dropbox.com/s/0ri8n4jb6gyrfz7/Screenshot_2014-11-17-20-56-01.png?dl=0
Now I'm trying to install X-posed Framework, but this won't work. When I try, I get an error that tells me /system can't be mounted. (Screenshot: https://www.dropbox.com/s/ryaryqkie023sl4/Screenshot_2014-11-17-20-40-16.png?dl=0 )
When I take a look is ES3 if the folder is mounted, it looks like this: https://www.dropbox.com/s/4kwv0ja16qz52tq/Screenshot_2014-11-17-20-49-21.png?dl=0 . I can't tick the other boxes here, I get the message "sorry, operation failed" when I try.
I've already tried to use the "mount -o remount,rw /" command, to no avail...
I have no idea how I have to fix this problem and if it's even fixable.
Does anyone have any idea? Thanks in advance!
Same here...
No solution for that yet.
Before you type the mount command did you type "su" first (without the quotes)?
Just opening up terminal gives you regular user permissions which will not let you run the mount command. You need to become root/superuser first and that's what su does.
Yes I did ... Terminal emulator gives a notification that It's been granted superuser permission, but it still doesn 't Work.
Sent from my Ascend Y300 using XDA Free mobile app
Can you send a screenshot of the "mount" comand and response?
Did the prompt change from $ to #? What was the output of "mount"?
If terminal doesn't work try with superuser adb (allow superuser not only from applications, but from adb). Connect to the device with "adb shell" and issue this command.
Hi, thanks for your response. Here are two screenshots: the first is of the mount command in Terminal Emulator, the second of the same via abd shell. No results.
Very strange, since filesystem seems to be remounted rw Ok.
In fact, I've installed xposed some two days ago on 101g9/cm10.2, so this should work.
Let's try to sort it out.
1) What version of xposed do you try to install? I've used latest stable (2.6 IIRC).
2) Do you use "standard" installation mode in xposed settings (just under the popup window on your screenshot)?
3) Try to issue the following commands in shell after remounting "/" (terminal or adb - doesn't matter)
# touch /system/bin/mytest.tmp
# ls -la /system/bin/mytest.tmp
If the file is created Ok, then the filesystem is mounted read-write correctly.
You can delete this file afterwards with
# rm /system/bin/mytest.tmp
4) Did you grant permanent or one-time superuser permission for xposed? If one-time, try permanent: it can be so, that "cp" fails due to lack of superuser permission.

1) I had 2.7 Experimental, so I uninstalled it and installed 2.6 Stable instead.
2) I do indeed use the "classical" option for installing Xposed.
3) Tried it, gave the following result: the file is created in /System/bin, so I guess /sytem is mounted okay. (see screenshots)
4) I use SuperSU, XPosed had root acces (see screenshot)
Seems to me /system is mounted fine, but Xposed just doesn't know it...
Ok.
The problem is with xposed, obviously.
For me, it complained that it can not remount /system (obviously), but then installed Ok.
So, what I would do
1) Check the filesystem mounts. May be, for some reason, you have /system mount (quite improbably, but nonetheless). Try in the terminal
# mount
It will show a list of all active mounts with the following format
[what is mounted] [where mounted] [blah-blah and stuff]
For example, from anothe device
/dev/block/platform/hi_mci.1/by-name/system /system ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
You can see that something is mounted at "/system" readonly ("ro" attribute)
2) Check if the /system/bin/app_process.orig already exists
# ls -la /system/bin/app_process.orig
3) Try to use logcat to obtain info. That is tricky
a) On the PC issue command "adb logcat > logcat.txt"
b) Start xposed installer, try to install, get an error
c) on PC press Ctrl-C

Alright, did all of it.
1) Don't fully understand what is listed here, but in the first screenshot is the list of mounts.
2) Checked it, doesn't seem to exist, see second screenshot.
3) Logcat is attached.
Ok, it appears that I got the problem. Need a little time to think how to solve this.
The problem is rather technical. In newer androids supersu has isolated filesystem mounts for different processes.
It means that if you remount filesystem rw in one process, it (read-write-ness) is not accessible to the other process.
I have a little older cm10.2 build (for low-memory devices), perhaps, this was enforced later.
http://su.chainfire.eu/#how-mount (3.5)
So you're saying there's a good chance that if I install version 22_12_2013-13_29_20 (which i was planning anyway), instead of the latest one, the problem could be fixed?
Hmm, I installed the previous version of CM10.2, the problem seems to be persisting...
I noticed something today. I can create and remove files in /system using the emulator. I can't however do this using ES3 file explorer, even though it has root access. I was trying to edit the build.prop file, but it wouldn't let me save my changes.
I then tried to copy a file to /system in es3, this didn't work. Creating a tmp file using emulator did work. Seems I do have rw access to /system, but not with all apps...

Well, it seems like what I've said, filesystem mount encapsulation.
I've noticed one thing - you are using the standalone supersu application. And for me superuser mode is integrated in the system settings near the developer options. May be this is the case, internal superuser is patched already.
Alright, I'll uninstall superSU for now, give it a go with the built-in superuser app. I'll let you know!
Supersu application, theoretically, could have replaced libsuperuser and other stuff integrated in the CM.
So, if just uninstalling does not work, perhaps it will make sense to reinstall CM itself.
P.S. I have mixed feelings with CM. On the one hand it is definitely more fluid, than 3.* or 4.* stock ROMs. On the other hand deep sleep works, well, strange, and the tablet sometimes freezes in the sleep or turns off by itself.
Yes, I have enabled deep sleep, but the battery drains definitely faster in the sleep. For me it is essential, since I mostly use it as a amazon kindle / google books / pdf reader terminal. And most of the time it just sleeps.

Eureka! I re-installed CM, issued the mount-command i used earlier and installed X-posed! I used the built-in superuser app, no such problems as before. I did have to issue the mount-command, but that isn't a problem Is it normal I have to re-issue the mount-command each time I want to access /system rw?
Thanks a million! I can't believe it was something this trivial But I'm so glad it's solved, thanks!

I don't use the deepsleep-option. I do use Greenify to ensure certain apps (like Youtube or Chrome) aren't active in the background. Boot manager to be sure only essential apps boot in the first place. This seems to save me some battery life. Airplane mode as well.
I got this tablet from my dad because it was so slow he couldn't work with it. Even after factory reset, it very quickly became sluggish again. With CM, it feels like it's a new tablet. So no doubts about CM for me
I do have another issue: My pc won't show the tablet in explorer. I can access it via ADB, but I can't access the storage via explorer... I suppose I best start a new topic for that...
Glad the issue was solved. I wonder why the superuser application didn't work.. Deepsleep - it allowed the tablet to lose, say, 10-15% charge during a week sleep. Very handy if the tablet is used not often - really miss it.
Explorer connection - if I remeber correctly, you should go to settings -> storage (where the size of apps/pictures etc is shown). Then press the three dots in the upper right corner, select "usb computer connection" and select MTP.
P.S. I wonder also if CM12/Android 5.0 in the "development" section is worth a try...
