Directory blind not working for most apps - Nexus 7 Q&A, Help & Troubleshooting

I'm on 4.2.1. I tried dead trigger, NFS, and temple run.
Only temple run worked. The other two want me to download the files again.
Sent from my Nexus 7 using Tapatalk 2

That's why I went back to 4.1.2.. 4.2's emulated directory structure doesn't behave well with file explorers or directory bind. The way to bind them is to make your former /sdcard source /storage/shell/emulated/0. My source was /sdcard/usbStorage/sda1/iBird_Pro, and it will bind if I make the source /storage/shell/emulated/0/usbStorage/sdb1/iBird_Pro. Notice it didn't bind using sda1. I had to unmount and remount the USB flash drive as sdb1. Also note, my apps wouldn't find the data at the target location, and Directory Bind won't let me make the target its true location at /storage/shell/emulated/0/iBird_Pro
I tried all the fuse, emulated, legacy, and symlinked alternatives. The only successful binding uses the /storage/shell/emulated/0 path.
/data/media/
/storage/sdcard0/
/sdcard/
etc. don't work
What works in 4.1.2
Formerly:
S: /sdcard/usbStorage/sda1/iBird_Pro
T: /sdcard/iBird_Pro
Has to be in 4.2
Now:
S: /storage/shell/emulated/0/usbStorage/sdb1/iBird_Pro
T: /sdcard/iBird_Pro
Should be:
S: /storage/shell/emulated/0/usbStorage/sdb1/iBird_Pro
T: /storage/shell/emulated/0/iBird_Pro

[HOWTO] for Gamers: dirty workaround to have Gameloft files on external_sd

No need for scripts. Search for GL to SD app, much easier.
------
I'm not a heavy gamer, but usually have tons of games installed on my phone for my kid to play with (trying to resist to the "daddy, I wanna a PSP" while I can, at least with the phone I can control when he plays ).
With the advent of HD games, it become more and more difficult to manage multiple game installations on sdcard. The last drop was Asphalt6, with its +500M of downloaded files.... soon will have to use external hard disks to use games on our phones . Most of the "heavy" games are from Gameloft, and the problem lies on the installation pack that doesn't ask for a location to install additional files, always assuming sdcard.
Looked around, and the only workaround I've found was a crack that opens the game apk and changes the download destination directory. Well, I wasn't very comfortable in using this, and it only worked on some games.
So I configured the following "dirty" workaround, I know it's not perfect, but it resolved my problem so I decided to share here.
Basically I've moved gameloft directory from sdcard to external_sd and created a bind mount point called gameloft on sdcard pointing to external_sd. This has the problem that you can only mount that bind point before using the gameloft games, because if you keep it mounted and use storage usb you'll have problems mounting sdcard.
So I've created two scripts - one to mount it, another to unmount it -, and using script manager created a shortcut (actually is a script manager widget) to both scripts on my screen. Whenever I want to use/install gameloft games I mount it, and in the end dismount the bind.
Additional steps for gamming, but restored my sdcard space and now I can use my 16G external sd for that files. Note that if your external card is slow, the game load will be slower.
EDIT: This procedure needs root and busybox. Sorry forgot to mention earlier, I never had my phone not rooted
So, the how-to for anyone who wants to try:
1 - copy /sdcard/gameloft to /sdcard/external_sd/gameloft (if you don't have any GL games installed just create the folder /sdcard/external_sd/gameloft)
2 - remove /sdcard/gameloft/ contents
3 - create the following scripts on sdcard:
mount_gl.sh
Code:
#!/system/bin/sh
# mounts bind point
if [ -e /sdcard/gameloft ];
then
if [ -e /sdcard/external_sd/gameloft ];
then
busybox mount -o bind /sdcard/external_sd/gameloft/ /sdcard/gameloft
else
echo "no gameloft dir on external_sd"
fi;
else
echo "no gameloft dir on sdcard"
fi;
umount_gl.sh
Code:
#!/system/bin/sh
# UNmounts bind point
if [ -e /sdcard/gameloft ];
then
busybox umount -l /sdcard/gameloft
else
echo "no gameloft dir on sdcard"
fi;
Run first to mount, and check /sdcard/gameloft/ contents. If everything ok, start game and try.
Remember that to simplify you can create shortcuts of the scripts using script manager.
Try not to leave the bind mounted. If by any chance you forget to unmount the bind and use usb storage, you wont be able to mount sdcard, but there's no need to stress . Just unmount usb storage, open adb shell (or a terminal on phone) and issue the command:
# umount /sdcard/gameloft
after that mount usb storage, unmount it again, and everything will be back to normal.
If you at some point regret the change, just move the content of /sdcard/external_sd/gameloft to /sdcard/gameloft/.
The usual disclaimer: I provide this to share my findings, use it at your own risk. AFAIK there's no risk on this operation, besides the fact you could have to download files again if something goes wrong, but I didn't test this on any other phones besides mine.
EDIT 08/19: updated scripts with feedback from thread - added busybox to mount/umount and added -l switch to umount.
Cheers
nice idea.
Can I do this method with symbolic link too?
No. Symlinks are not supported by fat filesystem, the only way I've found was trough bind mount point.

When i execute the script in script manager show me this error:

It looks like you don't have busybox installed. Do you have it?
My bad, didn't mention it on OP, sorry.
Try to open a terminal emulator on phone and execute:
$ sh /mnt/sdcard/mount_gl.sh
just to make sure its not script manager related.

u can use busybox umount -l /sdcard/gameloft in case umount doesn't work. when sdcard being used by some background program, normal umount not working. Tested with O2X though
I use JVR with latest semaphore kernel and i guess that this kernel has busybox v1.16.2. Am i wrong?

The code is wrong in the mount script, there's duplication
it should be:
Code:
#!/system/bin/sh
# mounts bind point
if [ -e /sdcard/gameloft ];
then
mount -o bind /sdcard/external_sd/gameloft/ /sdcard/gameloft
else
echo "no gameloft dir on external_sd"
fi;
and make sure you leave the /sdcard/gameloft folder where it is (even though it'll be empty)

can confirm this works, OP's unmount brings up 'files in use' or similar error sometimes..
on a side note, didn't know android was so picky when it comes to case.. if "Busybox" is used then you get a busybox: not found error, has to be lowercase
anyway, for the sake of clarity for other users:
Code:
busybox umount -l /sdcard/gameloft

I'm testing different locations, so no duplication. But be free to optimize the scripts, my programing is quite rusty this days.
Android is linux based, thus sensitive to capitalised words. About mount needing busybox, already happened to me on some rom/kernel combination. Using surface + talon and don't need to add busybox before the commands thought.
Sorry about the problems, like I said only tested on my sgs.

Dont have HoS, so thanks for the feedback. Maybe gameloft is making some control over the installed files because of illegal copy. Wish they put the same effort on resolving the installation issue, dont know why its so hard to ask the location instead of assuming a location for the download files.

I thought symlinks could do the trick as well (you wouldn't need scripts), but using mount points is a smart way as well! Thanks for sharing!

The script is generic, you can make it work on another Android Phone with internal SD such as LG, Atrix, etc.
I'm using this patch (Auto_Patch_APK_for_Samsung_by_Duero__include_Java_.exe) in order to place the game data into external memory. Most of Gameloft games work using this method except games which download from market. Just patch the apk file and after install them your game data will stored in folder Gl at your external memory.
So far only this games which not able to patch into external SD

Is it possible to mount and unmount usb storage via script?
What I'd like to achieve is the following:
usb storage mount script:
1. unbind directories
2. mount as usb storage
usb storage unmount script:
1. unmount usb storage
2. 10 sec pause
3. bind directories
This way, instead of running the script when playing games (or in my case, using music streaming app such as MOG and Grooveshark), I can run the scripts when I want to mount/unmount as usb storage. After all, I'd be using music apps more than I would use usb storage.

[Q] ADB Syntax to remount Micro SD Card?

I periodically get my sdcard to a state where it is read only. Not sure what causes this but a fix is to remount the sdcard. Currently I've been going into CWM and remounting it that way, but would like to do it via the terminal or adb. I found what I thought was the correct command online but I'm getting a usage error when I try it out.
Error:
Usage: mount [-r] [-w] [-o options] [-t type] device directory
Is this command correct for a Droid 2 (A955):
mount -o rw,remount -t /sdcard
Thanks!
I'll need to test this when I get home, but I believe you're missing the device before the directory. (ie. /dev/whatever)
Interesting. Copying and pasting your syntax worked fine for me. Sounds like you need a different copy of busybox. I'm running v1.16.2.
Huh? So it worked for you? Odd.
I just flashed the latest zombiestomped ROM (1.71) a few days ago and that has resolved the issue I was having that necessitated remounting my sdcard all the time. I never did figure out what was causing it to get locked into read-only mode.
Well I appreciate you verifying my syntax. At least now if I ever need to do that in the future I'll know what to do.
No problem. I can almost guarantee it was the version of busybox you had installed, as that's what provides the common linux tools like mount. They aren't the real binaries, but they're meant to be super-small applications that work just like the real thing, intended for small embedded systems.

[Q] Android 4.2: "Public" folder for every user?

Hi folks!
I searched the forum, but couldn't find a proper solution yet.
Is it possible to create a shared ("public") folder, which is accessible for every user on the N7?
As the user accounts seem to be managed under /data/media/ID I already tried:
adb shell
su
mkdir /data/media/pub
chmod 777 /data/media/pub
chown media_rw.media_rw /data/media/pub
ln -s /data/media/pub /data/media/0/pub
So logically the symlink is correct, unfortunately the user doesn't have access to /data/media (which I suspected), so the symlink to /data/media/pub is inaccessible for user 0.
Also other locations doesn't seem to work. On / and /mnt I cannot create a folder, as this is read-only mounted by default, and I don't want to fiddle around with various "mount -o rw/ro" scripts on bootup etc.
Does anybody managed to create a shared folder for every user?
Thanks in advance!

I'm having the same problem. I have a owner account in which I put some files (4 Gb) that should be available to every user. But user 10 and 11 can't access these files. Where Can I put those files, so that every account can easily access them?
I figured out that each user has a directory under /mnt/shell/emulated (0, 10, 11, etc.). So I created a directory "public" via root under /mnt/shell/emulated/public and made it worldwide writable via chmod -R 777 /mnt/shell/emulated/public. Afterwards I created public folders in each user directories.
It works like a charm when mounting via:
Code:
mount -o bind,allow_other /mnt/shell/emulated/public/ /mnt/shell/emulated/0/public/
I tried to build a simple script and it works when executing it in root shell via ADB. Unfortunately I didn't manage to automate this on boot. I couldn't find any "init.d" directory and also via "Script Manager - SManager" it wasn't working.
Code:
#!/system/bin/sh
PUBLIC_DIR=public
if [ -d /mnt/shell/emulated/$PUBLIC_DIR ]; then
for USER_PATH in /mnt/shell/emulated/*; do
if [ -d $USER_PATH/$PUBLIC_DIR ]; then
busybox mount -o bind,allow_other /mnt/shell/emulated/$PUBLIC_DIR $USER_PATH/$PUBLIC_DIR
fi
done
fi
Any ideas?
It's a start. It would be nice to incorporate it in an app.
It would be even better if it is a standard option in Android 4.2

I agree. At the moment, it seems to be possible only with a lot of fiddle and root including busybox. I don't know, if Google ever will implement such a feature, since it kind of breaks the separation idea of multi user spaces.
I hope, I'm able to figure out, how to get the script working. Everything works except the mount line which requires root privileges. Furthermore the script works correctly when executed from root shell via ADB.
Regards!
Did the updated super SU change anything?

I found an easy to implement solution to make a shared directory on the Nexus 7
I used ES file-explorer and set the setting so that it had all the read and write permissions and can go upwards to /
Then I make a new directory in /storage/emulated and give it some name. E.g. /storage/emulated/allusers
Then select the properties of this directory and change it so that everyone has all available permissions.
Now copy the files you want to share in this directory and change the permissions of these files as well.
Now you van change to another account and still read and write these files.
It's a bit of a hassle but it works
★******************
Well I Was too quick. The directory I created suddenly disappeared. I can't find the contents anymore. Where o where would these files go?

Has anyone tried “mkdir /data/media/legacy/pub" instead of “mkdir /data/media/pub"?
I noticed that every user has full access to this legacy folder... In fact, I kinda use this folder to move files between different users!
Well, yes it works. Need to be root though. But it works. Thanks a lot.
I found a solution.
Use the android/obb folder since it is shared space. I added a Movies folder there can can access it from multiple accounts. For MX player to see the movie files I had to uncheck the recognize no media option under settings but it works.
Thank you, I'll try this option too, Better than the solution mentioned above that needs root.

[TIPS][SCRIPTS][ROOT]egingell's scripts. Updated 11/22/13 11:30 MST

I will be using this thread to post my scripts and link them to other threads as needed. For this thread, I am assuming you know what you're doing. You don't need mad hacking skills and you don't need to be an expert (I'm sure as hell not), but knowing your way around the file system and basic shell scripting are helpful.
Some background: I am using the stock ROM and kernel (SGS2 - GB27, SGS4 - MDC), so all of my tips revolve around using stock and all of my scripts (even the flashable ones) will work without flashing from recovery (just extract the script from the ZIP and execute it while the phone is in phone-mode - you know... powered on ).
You are welcome to use my scripts in your apps. I only ask that you give me some credit.
I am not responsible for bricking your phone. I have only tested my scripts on my personal Samsung Galaxy S2 and S4 from Sprint. You are welcome to try on your phone, but I offer no warranties or guarantees as to whether they will work or not. Back up your ****!
All of this requires root!
Below is a list of the scripts I have written for y'alls. Enjoy.
Custom df: Shows where irregular mounts ("mount -o bind") are mounted. [ Forum post | Download ]
Currently doesn't work on my SGS4.
Easily move Phonesky.apk and GoogleServicesFramework.apk to /system or /preload for Multi DPI Play Store. [ Forum post | Download ]
Untested on my SGS4, but there's no reason to think that it won't work.
Use your SGS2's internal SD card for Link2SD instead of making a second partition on your external SD card (although, depending on the setup, you may still need to make a tiny partition on your external SD card) and your external SD card as your internal SD card [ Forum post ]
Untested on my SGS4. I have no need for it.
Clean up Link2SD: Delete files associated with Link2SD when uninstalling it. It does not revert the links Link2SD makes. It only deletes the mount scripts. [ Forum post | Download ]
If you use the debuggerd script to enable init.d, running this script will cause you to lose init.d.
Untested on my SGS4, but there's no reason to think that it won't work.
Delete Samsung's bloatware from the Sprint SGS2. [ Forum post | Download ]
Untested on my SGS4, but there's no reason to think that it won't work; however, it was written specifically for the SGS2's bloatware. See thread S4 System Apps Safe To Remove for a list of SGS4 bloatware apps.
Google Home Launcher (from Kit Kat).
Works on Jelly Bean.
Below are some other tweaks.
You can use custom boot animations with the stock ROM. All you need to do is swipe a "/system/bin/bootanimation" binary file from another ROM (such as @rujelus22's Blu Kuban FL24 (ICS) or Blu Kuban GB27 (JB 4.1.2)), paste it into "/system/bin", and make it executable.
For JB 4.2.2, make sure the user and group are root and shell respectively. This doesn't seem to be a problem with JB 4.1.2 and below. It's also possible that my initial testing involved a boot animation that didn't work on my SGS4, so if it works with root as both user and group, then roll with it. :good:
Also for JB 4.2.2, use the file from a JB 4.2.2 ROM, such as The Blu Kuban S4.
You can enable init.d scripts very easily by renaming "/system/bin/debuggerd" to "/system/bin/debuggerd.bin", replace it with the following, and make both files executable. If "/system/bin/debugger.bin" already exists, then edit "/system/xbin/busybox run-parts /system/etc/init.d" into "/system/bin/debuggerd".
As with the above, make sure the user and group are root and shell.
Code:
[color=green]#!/system/bin/sh[/color]
LOG=/data/debuggerd.log
echo "$(date)" > $LOG
echo "init.d" >> $LOG
/system/xbin/busybox run-parts /system/etc/init.d 1>>$LOG 2>>$LOG
echo "$(date) finished" >> $LOG
echo debuggerd.bin launched >> $LOG
exec /system/bin/debuggerd.bin
Below are some tips.
Most of the things you can do with a custom kernel, you can do with the stock kernel, it just requires more work and more risk.
If you replace an odexed system app with a deodexed system app, make sure you delete the app's ODEX file (it's the same file name except with the extension .odex).
Conversely: if you replace a deodexed system app with an odexed system app, you better have the ODEX file to go with it.
You can clear the dalvik-cache without a custom kernel by deleting the contents of "/data/dalvik-cache". You can even delete an individual app's dalvik-cache by finding the file "/data/dalvik-cache/[email protected]@[email protected]" or "/data/dalvik-cache/[email protected]@[email protected]" and delete it.
You can manually uninstall a system app's update by finding the file "/data/app/.apk" and delete it.
You can manually delete all user data by deleting the contents of "/data/data". You can even delete an individual app's data by finding the folder "/data/data/" and delete it.
Making scripts and binaries executable:
They must be on an EXT formatted filesystem (e.g. /data, /system, /preload).
They must be at least readable and executable by the user 'shell' (755 (read/execute for all, write only for user - "u=rwx,a=rx" if your busybox supports that method) is what I usually use).
Code:
chown root:shell ""
chmod 755 ""
chmod u=rwx,a=rx "" # busybox must support symbolic modes
Changing file permissions requires read/write access to the filesystem on which the file resides:
Code:
mount -o remount,rw /system # make the /system partition read/write
mount -o remount,ro /system # make the /system partition read only
The stock kernel is considered "production" whether or not it's rooted; therefore, you cannot use ADB to push or pull files directly to or from protected partitions, nor run ADB as root, nor use ADB's remount command, so you have to use unprotected partitions as a sort of buffer. You can, however, access the ADB shell and issue the "su" command wherein you can use "cp" to copy files to or from protected partitions prior to using ADB to push or pull the desired file. However, there is an app aptly named [root] adbd Insecure by @Chainfire that patches the ADB daemon to get around this limitation.
Example:
Code:
c:/android-sdk> adb shell
[email protected]:/ $ su
[email protected]:/ # cp /system/bin/debuggerd /sdcard/debuggerd
[COLOR="green"]-- open a new command prompt window --[/COLOR]
c:\android-sdk> adb pull /sdcard/debuggerd debuggerd
c:\android-sdk> adb push debuggerd /sdcard/debuggerd
[COLOR="green"]-- switch to the first command prompt window --[/color]
[email protected]:/ # mount -o remount,rw /system
[email protected]:/ # cp /sdcard/debuggerd /system/bin/debuggerd
[email protected]:/ # chown root:shell /system/bin/debuggerd
[email protected]:/ # chmod 755 /system/bin/debuggerd
[email protected]:/ # mount -o remount,ro /system
Some noteworthy files and folders:
/proc/self/mountinfo: If you can read it, it tells you where your partitions and folder binds are mounted.
/proc/partitions: Shows all of your SD card's partitions, how many blocks each has, and their vold numbers (eg "179 1 30578964 mmcnlk0p1").
/dev/block/platform/dw_mmc/by-name: This folder contains symlinks to your internal eMMC's partitions indexed by what they are for (eg UMS for your internal SD card - "realpath /dev/block/platform/dw_mmc/by-name/UMS" will print out the device path (ie "/dev/block/mmcblk0p11")).
/dev/block/platform/dw_mmc/by-num: This folder is like the previous except that they are indexed by partition number (eg "p11").
/proc/version: Shows what version of Linux is currently being used.
/data/system/batterystats.bin: Delete this when your battery is fully charged and still plugged in to recalibrate it.
Footnotes:
For "/data/app", "/data/data", and "/data/dalvik-cache" files you need to know the package name. There are various apps that will tell you, including Link2SD (mentioned above), Titanium Backup, and the web URL of the app in the Play Store (ex: https://play.google.com/store/apps/details?id=com.devname.appname).

Random boot sound using your notification sounds
The attached ZIP contains a script that can be run pre or post boot. It just needs to be executable.
Preboot requires init.d. See the OP for enabling it if you are on a stock rooted ROM and requires the file to be readable and executable ("chmod 755" works fine).
Postboot requires an app such as Scripter (ROM Toolbox) or Script Manager to execute the script at boot.
Requires the variable $RANDOM. You can make sure it's available from the command line ("echo $RANDOM").
Use this script at your own risk. I provide no warranties or guarantees.
What does this script do?
Check for carrier boot up sounds (sub folders in the "/system/media/audio/ui" folder) and moves them to "/system/media/audio/notifications" renaming them as needed.
Create symlinks in the above folders to "/system/media/audio/ui/PowerOn.ogg".
Check if "/system/media/audio/notifications/PowerOn.ogg" is present and copy it to "/system/media/audio/ui/PowerOn.ogg" it's not.
Count the number of files in "/system/media/audio/notifications".
Grab a random number between 1 and the number of files found inclusive (math notation: "[1, numFiles]").
Go through "/system/media/audio/notifications" and copy the file at index random to "/system/media/audio/ui/PowerOn.ogg".
Notes:
The stock file is included. If you want a different sound in its place, you can either comment out that line in the script and delete the "/system/media/audio/notifications/<subfolder>_PowerOn.ogg" files from "/system/media/audio/notifications" or just replace "/system/media/audio/notifications/PowerOn.ogg" with some other sound file and still delete the "/system/media/audio/notifications/<subfolder>_PowerOn.ogg" files from "/system/media/audio/notifications".
If you want more sounds, just copy them to "/system/media/audio/notifications" (OGG files only).
The script does not check for valid files and blindly renames the destination file to "PowerOn.ogg".
It does not look in "/sdcard/media/audio/notifications" or anywhere else for audio files.
I do not recommend using alarms or ringtones files as they are usually looped which can cause the media scanner to get stuck and overheat your phone or tablet - those files may continue to play even if you can't hear them.
If you can't hear a sound on boot, it is likely that the file is either invalid or has no audio (ex: my /system/media/audio/ui/BST/PowerOn.ogg has no audio).
It was tested and works on a Samsung Galaxy S2 (stock JB 4.1.2) and a Samsung Galaxy S4 (stock JB 4.2.2) both from Sprint and using stock kernels.
There's no obvious reason it won't work on other phones and tablets with other ROMs from other carriers.
Nice work E.

Make ADB work for all users - Jelly Bean 4.2.2 (Updated 07/15/13 00:35 MST)
With Android 4.2.2, ADB now requires RSA keys. This poses a problem when attempting to connect to the device's ADB server from the device itself and the device won't ask for authorization unless it's connected via USB. Well, there's hope, yet.
For the following, I'm assuming you used my method for adding init.d support to your device.
Use these scripts at your own risk. I provide no warranties or guarantees.
Add the following script to /system/bin/debuggerd. If you use an alternate method, please note that it must be executed by the debugger daemon. You must do this first or you'll have to manually restart the debugger daemon after editing this file and executing the run-once script (next step), so edit this file first and save it.
Code:
if [ ! -e "/.android" ]; then
busybox mount -o rw,remount /
mkdir /.android
mount -o bind /data/.android /.android
busybox mount -o ro,remount /
fi
Then run this script once from the device (not over ADB on your PC).
Code:
[COLOR="Green"]#!/system/bin/sh[/COLOR]
HOME=/data
adb kill-server
adb start-server
stop adbd
cat /data/.android/adbkey.pub >> /data/misc/adb/adb_keys
echo "" >> /data/misc/adb/adb_keys # Add a blank line at the end of the file
start adbd
HOME=/
adb kill-server
stop debuggerd
start debuggerd
Notes:
You can also find the abdkey.pub file on your Windows' PC here, C:\Users\<user name>\.android\adbkey.pub. Copy it to your device by whatever means necessary, then append it to /data/misc/adb/adb_keys and you won't need to initially use the USB to allow the PC connection. Not really necessary unless your PC has no USB or you've broken your USB cable.
This may have inadvertently corrected the mounting issue introduced in Jelly Bean 4.2.2.
You can also allow other Android 4.2.2 devices, but it requires ADB version 1.0.31 and for you to manually append the contents of /data/.android/adbkey.pub from device A (the one you want to use to ADB on) to /data/misc/adb/adb_keys on device B (the target device).
Don't delete /data/.android
This won't fix apps. Just allow you to use ADB to connect to your device from itself.
Tested on my SGS4. No reason it won't work on other devices.
If you already have a /data/.android directory, you may not need to do this. On my SGS4, HOME defaults to "/" which the ADB daemon can't write to, so it can't make the RSA key.
The run-once script temporarily changes HOME to "/data", a writable directory, so the ADB daemon can write the RSA key then it append it to the allowed clients file then restarts the debugger daemon thus binding /data/.android to the /.android directory allowing all Linux users ADB access to the device.
Reassigning HOME to a new value on one user only changes its value for that user which is why I'm binding /data/.android to /.android.
Code:
# Example
[email protected]:/ $ echo $HOME
/
[email protected]:/ $ HOME=/data
[email protected]:/ $ echo $HOME
/data
[email protected]:/ $ su 1000
[email protected]:/ $ echo $HOME
/
Alternatively (much easier):
Make the .android folder in /data (mkdir /data/.android).
Add the script, the first code block in this post, to your debuggerd file or an init.d script.
Restart the debugger (stop debuggerd; start debuggerd) or reboot the phone.
Restart ADB (stop adbd; start adbd).
Copy the newly created public key to the allowed clients (cat /data/.android/adbkey.pub >> /data/misc/adb/adb_keys; echo "" >> /data/misc/adb/adb_keys).
Restart the ADB server (adb kill-server; adb start-server).
SGS4 Bloatware Remover
I have written a live-script to delete all of the SGS4 bloatware except GoogleContactsSycAdapter and SecLauncher3. If you want to delete those, remove the "#" from that line in the script. If you want to exclude an app, add a "#" to that line and put the app name in quotes (ie AppName / becomes "#AppName" / (including the forward slash) or just remove that line. If you remove the last item (YouTube in this case), remove the forward slash from the previous line.
Use this scripts at your own risk. I provide no warranties or guarantees.
What this script does:
Move the app's APK and ODEX to /sdcard/SystemAppsBackup.
Delete its dalvik-cache.
Reboot the phone. If it doesn't reboot, you'll have to do this yourself.
What this script does not do:
Delete the app's data. Because the script doesn't know the package name.
Delete its Play Store update (located in /data/app). Because the script doesn't know the package name.
Mount the SD card if it's not mounted. If you want backups, make sure the SD card is mounted.
Care if you delete a system app you wanted to keep. Most apps that you would want to keep may be available in the Play Store.
Restore apps.
Notes:
Apps will crash left and right when you execute this script in running mode. Don't fret, this is normal.
This is a live-script which means you have to manually execute the script either with a terminal emulator, a script executor like Scripter, or ADB.
This is not flashable.
If executing via ADB in Recovery mode, you may need to mount the SD card to /storage/sdcard0 manually or settle for no backups.
If you restore an app from /sdcard/SystemAppsBackup, make sure you get the ODEX file if present and set the permissions for both to 644.
This list is based off the list in the thread, S4 System Apps Safe To Remove.
Here You Go Guys, I took me about 30 mins, but I have successfully added all the app in the Op to a flashable Zip.
The Zip is base of TrulyClean v1.6 script code, I just deleted his ;delete/system/...apk and replaced it with all the ones from the OP

Did you install GravityBox on your SGS4 then uninstall it and now you can't hear your games or music?
I think it has to do with GravityBox's "Volume Steps" option not undoing when GB is uninstalled. This is how I fixed it (forum post).
Stock ROM - SGS4 - init.d
I recently found out that my debuggerd hack to enable init.d support on my stock SGS4 wasn't working. So, I did this and now it works.
Make a file named "install-recovery.sh" and drop it into /system/etc. Whatever script you put in here will execute at boot up so long as the user/permissions are correct.
Code:
chown shell:shell "/system/etc/install-recovery.sh"
chmod 755 "/system/etc/install-recovery.sh"
chmod u=rwx,a=rx "/system/etc/install-recovery.sh" # busybox must support symbolic modes
Use this script at your own risk. I provide no warranties or guarantees.
My "/system/etc/install-recovery.sh" script:
Code:
[COLOR="Green"]#!/system/bin/sh[/COLOR]
LOG="/data/install-recovery.log";
echo "Executing install-recovery.sh" > $LOG;
echo "" >> $LOG;
echo "$(date) install-recovery hack..." > $LOG
echo "" >> $LOG
echo "init.d" >> $LOG
[COLOR="green"]# I can't get run-parts to work for some reason, but this will run every *.sh script in /system/etc/init.d as root.[/COLOR]
for N in /system/etc/init.d/*.sh; do
su -c "$N" 1>>$LOG 2>>$LOG
done;
Notes:
Mount binding (in JB 4.2.2+) seems to work. E.g. mount -o bind /folder1 /folder2
$(date) does not provide the correct date (mine said: "Wed Apr 15 13:24:13 MST 1970").
The Package Manager is not available. (There may be other unavailabilities, but I don't intend to test it thoroughly.)
Somethings I discovered recently while doing a no-data system restore for the second time in the same night and some tips relating to system restores:
* When doing a no-data restore, disabled/frozen system apps remain disabled.
* Apps that can't be disabled even with Titanium Backup will not remain disabled after a reboot and will sometimes crash/FC repeatedly until uninstalled.
* If an app won't open or FCs, try converting it to a system app and back to user app or vice versa.
* Don't integrate system app updates into the ROM. In the event that you have to do a no-data restore, those updates will be retained.
* Don't convert user apps to system apps for the same reason.
* Disregard the previous two tips if disk space is a problem. It's just more time consuming (redownloading updates, reintegrating, and reinstalling) after a restore.
* Save all modified system files, such as /system/bin/debuggerd, /system/build.prop, /system/etc/install-recovery.sh, and if your ROM uses /system/etc/unit.d, any modified or extra files there. If you use them, you'll need them after a restore.
* For a smoother post no-data restore, use Titanium Backup's labels so you can batch-uninstall those pesky system apps you don't want.

Creating directories in / and all the files contained therein must be redone on every boot. That said, you just need to make root writable and make the directory.
mount -o remount,rw /
mkdir /whatever
mount -o remount,ro /
Note: Every time you wish to create, modify, or delete files you'll have to make root writable.

Ouya SD Card Mount Enable [SD Card Read FIX]

Lets start by saying i did not have anything to do with the making of this I'm just re-posting for the people who had it tough like me.
What i did was use Ouya Tool Box to root, su, busy box etc.
Installed ES file explorer, ES Task Man
Edited /system/etc/vold.fstab
--------------------------------------------

This should be able to be done on any Ouya since they are all rooted, but you have to have root access.
This fix will give you full access to your USB flash drive as a "sd card". It will even be listed in the 'storage settings' and will be visible from Windows under the "Ouya Console" drive that pops up when it is connected.
First you must mount /system read-write. You can either use adb shell, or sideload "Android Terminal emulator" if you have a keyboard:
adb shell
mount -o remount,rw /system
After this you need to edit the file /system/etc/vold.fstab. There will be two lines at the end:
Change this:
dev_mount sdcard /storage/sdcard1 auto /devices/platform/sdhci-tegra.0/mmc_host/mmc2
dev_mount usbdrive /mnt/usbdrive auto /devices/platform/tegra-ehci.2/usb2
to this:
#dev_mount sdcard /storage/sdcard1 auto /devices/platform/sdhci-tegra.0/mmc_host/mmc2
dev_mount usbdrive /storage/sdcard1 auto /devices/platform/tegra-ehci.2/usb2
How does this work? Well, the first line, we comment out. It refers to a storage device on the tegra that is connected to nothing at all, basically the on chip SD/MMC that we have no slot to stick said MMC card to. The second line, we tell vold to detect the USB stick we boot with or insert, as a SD card. Really any storage device can be here (try it with a hard disk!) but in our case we want the first USB storage device to be here. In theory this hotplugs well, as I have tested removing it and reinserting it locally. It will look like an SD card to the Ouya. I am going to test moving an app to it and running it in a moment.
Really this file hack should not be necessary, the proper way to do this is editing init.rc and changing
export SECONDARY_STORAGE /storage/sdcard1
to
export SECONDARY_STORAGE /mnt/usbdrive
However /init.rc cannot be edited without modifying the bootloader, and since Ouya has no button to go into recovery yet, I am not willing to risk or even talk about editing /init.rc in your boot image.
Anyway, if anyone else wants to try this and confirm it works for them i'll watch this thread for a bit. Maybe the Ouya devs can incorporate it into a build, or just set SECONDARY_STORAGE in /init.rc right.
However the fix I just gave is easier because if you change SECONDARY_STORAGE you're gonna have to change every reference to /storage/sdcard1 down the line.

FYI, they might have included it in an upgraded, since my usb cards gets mounted to: /mnt/usbdrive, but there also seams to be a symbolic link in the root folder, which is quite nice.

sadly I I did not like the way that was working. So I found this method. It shows you in the storage menu that you have something mounted (SD it says) It feels more natural and I don't know if its a placebo effect but things are faster and xfering faster
Help?

!!!! please don't use this method now. I tried it a few days ago and it did not work after a Ouya Update. sorry. i should have mentioned.

ES definitely shows the USB drive as a USB drive, which as a result, has made ePSXe (installed from the Play Store) able to find my PSX ROMs. RetroArch still says sdcard0 and sdcard1, and on sdcard1 (the USB drive), it shows as empty.
What to do?

i dont know what else to tell you homie. when my ouya turns on i look to see if the LED indicator is blinking "access" behaviour. If it doesn't it didn't read it. If you don't have a LED sorry. check /mnt/usbdrive thats what i use now. all my emus etc. can see it.

It's definitely being read. Has a little blinking LED. If ES and ePSXe are reading it, I know it's working. Just gotta figure out why RetroArch won't read it, or find some other emulators that will.
What emulators are you using?
If you got the PSX emulator to read your Roms already then it sounds like it is the Retroarch messing up. I would recommend loading individual emulators anyways.
