Introduction
This is my first Android application and I'm looking for testers and feedback.
LUKS Manager
LUKS Manager provides on-the-fly encryption (AES by default) to virtual folders on Android devices.
The virtual folders can be dynamically mounted, unmounted, created and deleted as needed.
(Think TrueCrypt like functionality)
Volumes and loopback device information are stored in: /mnt/sdcard/luks/.data
And the encrypted volumes are mounted at: /mnt/sdcard/luks/<volume_name>
Requirements
The Android device must:
Be rooted
Have a kernel that supports secure dm-crypt modes and loopback devices
Have a current version of BusyBox installed
Have SuperUser app installed
This package contains:
A statically compiled, stripped and UPX compressed version of cryptsetup for the ARM using the tools provided by the The Guardian Project.
A statically compiled and stripped version of mkdosfs from dosfstools package for the ARM7.
A bash shell script called "luks" that does volume management.
And a native java app that provides a GUI interface to the luks script, a basic file explorer and simple text editor.

Won't download the full file on my phone using the stock browser and dolphin HD. 1 star because I can't install it. Just joking, but can you put up a mirror please? The download link seems to work fine in Chrome, but mobile browsers it seems to crap out on.

OK. I believe I've fixed mobile downloads on the server so please try again.
And I've also updated LUKS Manager to v1.4. (lots of little fixes, tweaks)

Thanks for catching that. Version 1.5 should now quote passwords properly.
Any other issues? (I know I should validate user input more on volume creation; but the luks script should handle failures gracefully.)

Released v1.6
Version 1.6 notes:
Images updated and optimized using optipng.
Updated the about box text.
Added additional failure logging to syslog.
And did a small bit of code cleanup.
just tried this on my hero and its almost very good it seems to create, mount and unmount ok but i'm getting an error that it cant find mkdir (i think this might be because my busybox is in /system/xbin rather than /system/bin?) and also the graphics for the buttons dont seem to resize so on a low resolution screen they overlap and arent readable.

Ok, I switched over from pixels to dp units. It seems to render fine in the emulator with the display settings for the Hero. Please let me know if it works.

Thanks looks great now on the screen, still have a problem mounting though, could it auto-detect the location of busybox or have a changeable option?
Some feature recomendations to consider:
* auto-mount select volumes on startup
* auto-dismount all volumes on shutdown
* auto-dismount all volumes on X number of failed lockscreen attempts
* graphical support for moving/linking directories/files into encrypted volumes (so we can link our folders for downloads, camera, dropbox, etc. to the volumes directly)

Looks like kernel problem... Any way to fix? YES.
Compile sha256_generic.ko as module, insmod it and all works normally.
Important note - kernel compilations with default NDK toolchain creates
broken module - kexec error - bad relocations: 27 - R_ARM_PLT32.
To compile correct module for your kernel use code sorcery arm compiler.

on which roms it is working ? i have zte blade - i know wrong topic but what rom should i install to have it working ?

I think it'll work on any rom that has root, but I could be wrong. I use the latest CyanogenMod Nightlies.
Xtam, 2.0 GUI starts working for me with cyanogen 7.x ROM. It requires sha256_generic.ko module for aes-cbc-essiv cipher (FreeOTFE volume), but aes-cbc-plain volume works without additional modules.

Ron,
I'll look into/consider adding some of those. I've add some code to unmount the volumes on shutdown but I'm not 100% sure it's working properly.
I like the idea of unmounting them all on after X number of failed lock screen attempts. Not quite sure how I can hook into that however.
In version 2.1 you can set the mount point; not sure if I'll write a GUI interface for symlinking however.
-N2
I'm having problems unmounting volumes in 2.1. Whenever I attempt to unmount a volume it tells me without any errors its unmounted, but when you try to remount the volume or check the status its still mounted.
I have a Samsung Infuse which is basically an i9000 galaxy S with a bigger screen and like most galaxy S devices I know of, it has internal storage which is mounted to /mnt/sdcard and an external sd card which is mounted to /mnt/sdcard/exteral_sd. I really like the app and it works perfectly, however I have a problem. It wants to create the volume on the internal sdcard instead of the external one. I edited the lukspath in the luks script but it keeps overwriting it when I start up the gui and go to create a volume. Is there a way to make this setting stick in the luks script without recompiling? Or could you update the app to allow people to change where it creates the volume? I just need to be able to create a volume in /mnt/sdcard/external_sd/. Thanks!
Nice app, thank you Nemesis.
Another suggestion for improvement: it would be nice to be able to change a volume password.
Instead of moving all applications to SD card with app2sd, I want to move only selected applications.
Because I don't want to move my launcher, soft keyboard and dialer application to SD and make them unavaliable on boot if my SD card has problem or not inserted.
The idea behind is same, linking to SD card's second partition but differs in two ways.
One, instead of linking /data/app folder (that means moving all applications), you can select the applications that you want to move.
Two, it's an application which means has a user interface. You can manage your applications, create or remove links with just few clicks.
It also provides native apps2sd features on Android 2.2 and higher. Plus, it can move any non-protected user apps to SD card (force move), with batch moving capability.
That feature uses Android's standard SD-card installation feature and does not require a second partition. It can break some apps if they are not meant to be moved to the SD card (Such as Widgets).
Features:
- Create and remove link for apk, dex and lib files of the applications you select
- Automatically link newly installed apps
- Move any user apps to SD even though the app does not support moving to SD (for Android 2.2 and higher)
- Shows the apps that support moving to SD with native apps2sd (for Android 2.2 and higher)
- Set the default install location of the apps; auto, internal, or external (for Android 2.2 and higher)
- Batch link, unlink, reinstall, uninstall, "move to SD", "move to phone" functions (multi-select mode)
- Uninstall system applications
- Freeze and un-freeze system and users applications
- Convert system apps into user apps
- Convert user apps into system apps
- Integrate "Updated" system apps into system (ROM)
- Clear data and cache of the application
- Clear all apps cache at once (1-tap cache cleaner without being root)
- List applications, show detailed size information and link status
- Sort and filter applications
- Search applications by name
- Display available space information of internal storage, SD card and SD card 2nd partition
What you need for linking applications:
- root permission
- a second partition on your SD card. You should have two partitions on SD card and both should be primary
The first FAT partition is your standard SD card storage. The second partition is used for application files and can be ext2, ext3, ext4 or FAT32.
ext4 is the latest ext format but several ROMs have issues with it while fewer have issues with ext3 and ext2. FAT works on all ROMs.
I use free "MiniTool Partition Wizard Home Edition" (windows application) for this.
You can create the second partition without repartitioning, formatting or deleting your existing partition with this tool. Connect your SD card to PC with a card reader or phone itself and make it visible as a drive. Open Minitool select this drive and resize down FAT partition, you will see an unallocated area at the end of the card. Create ext2, ext3 or FAT32 partition in that area (create as primary, not logical), click apply. Unplug from the PC and reboot the phone. (To be on the safe side backup your SD card data before starting)[/LIST]- That's all. Just install Link2SD, it will do all necessary. No need to copy files or run scripts.*
* Some phones lack the ext2, ext3 or ext4 file system support and you may get mount errors like "no such device", "invalid argument". These phones need a matching ext2.ko or ext3.ko modules and even some additional modules to be able to mount.
Using FAT32 on the second partition will eleminate such problems, because FAT32 is supported on all phones.
How it works:
Link2SD mounts the second partition of your SD card as /data/sdext2 and makes OS mounts it at boot time.
When you select an application and press "Create Link" button you can select which files of the application will be linked and moved to SD card. Apk, dex and lib files can be moved and you can select all three or any two of three or even only one of them.
Depending on what you select, Link2SD moves apk file, dalvik-cache (.dex) file and lib files (.so) to SD card's second partition and creates symbolic links in original directories.
Note: On Android 1.6 and 2.1, shortcut and the widget of the app should be re-added to homescreen if you move the apk file.
Can I remove the links and put application files back to phone?
Yes, just click on application that is linked and press "Remove Link" button. You can select which files of the application will be unlinked and moved back to internal storage.
Then, Link2SD removes the symbolic links and moves the files you selected to original directories.
What happens if I uninstall or update a linked application?
If you uninstall a linked application apk, dex and lib files will be automatically deleted from the SD card by Link2SD.
If you update a linked application new apk, dex and lib files will be placed in the internal memory at first and then they will be automatically relinked by Link2SD in the background.
You don't have to manually relink after updating applications.
Note: Since the app is linked again, On Android 1.6 and 2.1, shortcut and the widget of the app should be re-added to homescreen if the apk file is linked
Some points
- System applications should not be linked to SD card. Link2SD does not allow these applications to be linked.
- When you connect your phone to PC as mass storage, Android unmounts FAT partition but the second partition remains mounted. Therefore linked applications are not affected and can be run without problems.
- Link2SD does not move application's private data directory; it moves apk, dex (dalvik-cache) and lib files

fat32 is usually supported by almost all roms .
I have a problem when the SD card is partitioned with more that one partition and if is enabled the MSC transfer mode (mass storage mode):
The latest files (e.g. camera pictures) and/or folders are not displayed on PC
This behavior is not visible when the MTP transfer mode is used for connectivity. I'm using the MSC mode for systems compatibilities (Windows / Linux / MAC OS) and my phone.
I tested with three cards (Silicon power, Kingmax and a non name one).
My phone is: MT15i, Android 4.0.4, firmware 4.1.B.0.587, kernel 2.6.32.9-pref
I partitioned:
- first partition - primary partition with fat32 format; (partition size = SD size - 1,5 GB for second partion)
- second partition - primary partition with ext2 (only this format is recognized by my kernel) also I tried and fat32, but I have same problem (maximum 1,5 GB)
I made partitions using:
- GParted - from a live CD and from an Ubuntu 12.04;
- MiniTool Partition Wizard Home Edition 7.6.1 - from my Windows 7 PC;
- DiskUtility from a MAC OS.
The results are the same: the latest files or folders from SD card don't appear on the PC.
Scenario:
1. open the phone;
2. take one picture: DSC_0001.jpg;
3. connect to PC, DSC_0001.jpg is visible on the attached card;
4. disconnect the phone from PC;
5. take another picture DSC_0002.jpg;
6. connect again the phone to PC, only DSC_0001.jpg is visible.
7. reboot the phone (shutdown then power on);
8. connect the phone to the PC: DSC_0001.jpg and DSC_0002.jpg are both visible.
9. take a third picture DSC_0003.jpg;
10. connect the phone to the PC, only first two images are vizible (DSC_0001.jpg and DSC_0002.jpg)
...
After each reboot all files / folders are showed correctly when the phone is connected for the first time.
All this time, the files are stored and displayed correctly on the phone using a file explorer or an album program.
Also, if I'm reading the SD card using an external card reader, all files and folders appear ok.
Anyone have any idea what could be wrong in my case?
What else informations could be helpful?
I attached some files from my phone (/ and /etc/)
Thank you for your time!
Later edit
A possible fix is to install a custom or an original rom. Actually this fixed my issue until I installed again Link2SD with partition mount script.
I installed: [ROM]=- Xperia Ultimate HD™ 2.0.3 -= [ Stable like a Rock ] & [ Best User Interface ] after that I was able to attach my phone using MSC mode multiple times and I can access latest files / folders.

I have a problem when the SD card is partitioned with more that one partition and if is enabled the MSC transfer mode (mass storage mode):

This behavior is not visible when the MTP transfer mode is used for connectivity. I'm using the MSC mode for systems compatibilities (Windows / Linux / MAC OS) and my phone.
I tested with three cards (Silicon power, Kingmax and a non name one).

open your link2sd, on 1st time it will ask you to choose mount script which kind of partition you use
after that reboot your phone.. open link2sd if it show same dialogue like 1st time open link2sd reboot go to cwm and mount your sd-ext
hmm... did you link your galery?? if yes unlink it
sorry my bad english

which file system(Fat 32,ext2 etc) should be proper to use with MT11i
Thank you for your answer.
Actually my problems is visible only when I attach my phone second time to PC, after a restart.
Opening the Link2SD I'm not asked to enable the mount script, because this script is already installed and running ok, I guess, because the second partition (/data/sdext2) appear on Link2SD -> Storage Info (see attached image).
Also I'm able to navigate through that linked folder (/data/sdext2/)
The behavior is like first time when I connect my phone to the PC, on the phone is created a 'cache' from where, on second / third / ... time are provided same informations (files and folders are same like on first connection).
I'm suspecting one of scripts: init.semc.rc or init.usbmode.sh (these files are recreated at start up / booting)
I'm not sure if I'm right.
Answering to aakash43
Try for first time to create two partitions with following formats:
- first partition: fat32
- second partition: ext2
More informations you can found here on the official page: Link2SD - Description - What you need for linking applications. ( link2sd.info/description)
If second partition is not mounted try to format to fat32. It is indicated to use a unix file format (ext4, ext3 or ext2) but depends by your phone kernel. In my case the phone (Neo - MT15i with latest firmware) was not able to recognize ext4 or ext3 format.
I want to know that Creating second partition in sd card will delete the data present in sdcard.
Answering to aakash43
Depends what program you use to make partitions.
For example I used, on Windows, the MiniTool Partition Wizard Home Edition 7.6.1
I resized first partition and I added on the remaining space a second partition. I did not lost any file from first partition, but to be sure copy all files to PC, be careful to get hidden files and folders also.
But for a safe partitioning process, back-up all files and folders (including hidden files and folders) to PC first.
And delete all existing partitions and recreate new partitions. Remember, all partitions should be primary and visible.

Great info! :good:
workaround for my MSC issue
I figured it out a workaround in my case, for the issue detailed on previous page at post #9.
It is important to have your phone rooted!
I flashed with a clean firmware (4.1.B.0.587) my phone (MT15i), I rooted my phone and I placed a customized rom: [ROM]=- Xperia Ultimate HD™ 2.0.3 -= [ Stable like a Rock ] & [ Best User Interface ]
I opened the phone and I let it to install and configure all applications.
I rebooted twice to be sure all configurations are made properly.
I turned off my phone, I removed the SD card and I partitioned the card using my laptop card reader.
I partitioned using the MiniTool Partition Wizard Home Edition 7.6.1 on mine Windows 7 machine:
1. I deleted all partitions from my card (previously I had some partitions);
2. I created at the end of the card one primary partition with ext2 file system format; (previously I tested others formats ext3 and ext4, but seems to not be recognized these formats)
3. on the remaining space I created another primary partition with FAT32 file system format.
Like on below image:
I placed formated card into the phone and I turned on.
I modified the file: /system/etc/vold.fstab
I replaced:
Code:
dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.4/mmc_host/mmc0 /devices/platform/msm_sdcc.4/mmc_host/mmc1
with:
Code:
dev_mount sdcard /mnt/sdcard 1 /devices/platform/msm_sdcc.4/mmc_host/mmc1
Format is:
Code:
Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
To found that solution I made some tests after each modification on /system/etc/vold.fstab I rebooted my phone. And I checked to see if the /mnt/sdcard is mounted properly.
I modified the file on PC and after each time I pushed modified file to the phone:
Code:
adb push vold.fstab /system/etc/vold.fstab
(you should have the terminal on the current folder where is your modified file)
Then, with my phone connected to PC I tried to mount the second partition to /data/sdext2/ folder.
Open a terminal and add below commands:
Code:
>adb shell
$su -
Your terminal should look like (this is in Windows):
Code:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\ciubex>adb shell
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
[email protected]:/ $ su -
su -
[email protected]:/ #
This folder was not on my phone, so I created: #mkdir /data/sdext2/
On PC terminal I tried to mount the partition using the command:
Code:
mount -t ext2 -o rw /dev/block/mmcblk0p2 /data/sdext2
After each mount attempt you can check if the partition is mounted by using df command, the terminal should show like:
Code:
[email protected]:/ $ df
df
Filesystem Size Used Free Blksize
/dev 169.9M 76.0K 169.9M 4096
/mnt/asec 169.9M 0.0K 169.9M 4096
/mnt/obb 169.9M 0.0K 169.9M 4096
/system 312.5M 310.7M 1.8M 4096
/data 380.0M 140.0M 240.0M 4096

[b]/data/sdext2 1.4G 82.6M 1.3G 1024[/b]
[email protected]:/ $
If your second partition is mounted properly, you can proceed to install Link2SD.
I installed Link2SD, I let the software to generate mount script /system/etc/install-recovery.sh.
I don't rebooted, but I modified generated file by removing the line:
Code:
I let only the mounting:
Code:
mount -t ext2 -o rw /dev/block/mmcblk0p2 /data/sdext2 1>>$LOG 2>>$LOG
Be careful to have an empty last line.
To exit from terminal, use commad: exit
After that I rebooted my phone.
Now I do not have any more problems with my latest created files or folders on the phone, when I connect the phone to PC using MSC protocol.
I attached an archive with modified files (vold.fstab and install-recovery.sh).
i used cwm recovery of lupus kernel and it partitioned my mc into fat32,ext3 n its running flawlessly
when I try to create partition using mini tool partition wizard the unlocated space does not increase above 304 MB plz help
Steps to make partitions
I really don't know what's wrong in your case, is your card empty? It is your card full and remaining empty space is 304MB?
But let suppose you have inserted a formatted card into a card reader with a single partition and want to have two partitions.
Method 1:
resize existing partition and create a second one:
- right click on partition
- select 'Move/Resize'
- click on right side of the partition image from 'Size And Location'
- move the border on left side to desired partition size
- click on 'Ok'
- now on the disks images should appear resized partition and an unallocated space at the end of the card
- right click on the Unallocated space
- select 'Create'
- on the Warning message press 'Yes' (Warning message: The new created partition cannot be used in WIndows....)
- on the 'Create New Partition' dialog window chose:
--- Create As: Primary
--- File System: Ext2
--- Press 'OK' button
- Now, your card is ready for modifications: Press Apply.
Method 2:
in that case the entire card is erased and partition(s) is (are) deleted firstly and created from beginning
- right click on partition or on each partition from card and select 'Delete'
- when entire card appear as Unallocated
- let create second partition at the end
- right click on Unallocated space and select 'Create'
- resize the partition image from 'Size And Location' by clicking on the left side and moving the left border to the right until the new partition have desired size
- select:
--- Create As: Primary
--- File System: Ext2
--- Press 'OK'
- now will create first partition
- right click on the Unallocated space
- select 'Create'
- on the Warning message press 'Yes' (Warning message: The new created partition cannot be used in WIndows....)
- on the 'Create New Partition' dialog window chose:
--- Create As: Primary
--- File System: FAT32
--- Press 'OK' button
- Now, your card is ready for modifications: Press Apply.
That's all.
This is the one I used ^^
I created a ext3 partition on the sd card, I selected what I want to moved or not.
And now, all new apps are installed on the sd card automatically.
Works great , thanks.
Now that, our tablet S is now rooted finally .... thanks to all fellow users and developers for achieving this :highfive:
After rooting, i wanted to try Directory Bind developed by slig.. target to free up some space (internal sdcard). And result, this app is damn good guys! I have Maxpayne, GTA3, 9MM, Asphalt 6, Shadowgun. With all these games installed, i have 8.1gb from 8.9gb in internal storage (source: Sony's File Transfer) :laugh:
Requirement to make this work on sony tab, is ROOT, Enable write permission on sd patch from condi's S.ony Aio
Sounds cool? give it a try
Here's original thread [TOOL] DirectoryBind - move data to external_sd (GameLoft, Shadowgun etc.) ROOT req.
Hi all !
This is my application to bind directories located on external_sd to directories on internal memory (/sdcard/). This way You can transfer large application data directories to external_sd. Could be usefull with ex.: games from Gameloft, other like Shadowgun, applications like CamScanner.
Features:
* Requires ROOT !
* Aimed at specific functionality and features (not idiot-proof)
* You can create any number of Data -> Target directory pairs, mount them manually or choose to mount them on system boot (checkbox does that).
* On/Off switch controls whole mount-on-boot function.
* Diskette icon indicates if mount operation was successful, by taping it You can mount/umount entry.
* Icon changes if application is using mounted entry
* DirectoryBind can tell what application is using this entry (tap at entry in use)
* Long tap on entry (disabled) brings edit/delete window
* App auto umount all entries on USB connected and remount after USB disconnected (for now via BroadcardReceiver UMS_CONNECTED / UMS_DISCONNECTED)
* App shows notification and vibrates if auto umount on USB fails
* If mounting all checked entries (ex. on boot) app is waiting specified time (def. 60 sec) if data directory is not available (happens sometimes at boot)
* Tested sucessfully with Asphalt 6, Shadowgun, DeadSpace, CamScanner

Installation and usage is pretty simple. No format of card or extra partition required.
Just install the application and it will ask for root rights. Click allow and you are in the main screen. Now FIRST step, click menu and go for prog "preference" and there click bind on boot, 'alternate dbase mgmt"
and also check default data path, target path and assistant prefix dir- if reqd.
Now start adding games to move data, Add new entry -> click menu -> Data transfer assistant.
Click on the directory you want to transfer and select. -> and tick Transfer files from target to data. and finally click ADD
Now app will create similar path directory on your external sd card and will transfer all data files to same on your external sd card.
Once this transfer is completed, and click menu and click "Bind Checked" All done, data is now on your sd card and test your games.
Rest go through the original thread, after some tries you will succeed. Good luck guys :good:
edit:
Now added Asphault7, Brother in arm 2. Internal memory 7.8gb left
That's Cool！！！
This is very frustrating... expert help needed. I have a Samsung Fascinate running AOKP JB 4.2.1 under a clean install (...formatted my system, data, datadata, cache & dalvik prior).
On phone startup, "media storage" seems to scan all internal audio files. The audio list exists... but after a while, the list just disappears and I no longer can choose my ringtones, music, etc. from any application depending on "media storage". I found out the list of media files are in the "internal.db" database under /data/data/com.android.providers.media/databases. So I cleared the "media storage" data, restarted the phone, n observed the folder contents...
On startup, "internal.db" shows up @ ~100 kb and doesn't change in file size. What does change in size is the accompanying wal-file, "internal.db-wal". According to sqlite.org, the wal-file will maintain the audio list and commit it to the database "internal.db" after so many records. Yet, at some point this wal-file drops from ~700 kb of records to 0 kb... no idea why. This is when i can't access my music.
For a long time, this wasn't an issue. I believe the records from the wal-file were already successfully committed to the database. Then I must've cleared the data (for some reason), thereby having "media storage" rebuild the database from scratch... and ultimately revealing an issue with the wal-file. I've even uninstalled the "media storage" package "mediaprovider.apk" from /system/app via TitaniumBackup. Rebooted. Then reinstalled the apk to /system/app. Rebooted. Same issue happens! All else is working perfectly.
I'm no sqlite expert, but is there some way i can force the wal-file to commit? Any other advice? Yes, I googled all i could think of. And i'd like to avoid reinstalling my ROM. Your help is greatly appreciated.
[EDIT]
Found a workaround...
1 - Delete the contents of the folder /data/data/com.android.providers.media/databases.
2 - Reboot and wait ~5 min after startup to let the media store reindex all ur media. DO NOT configure any app's ringtones/sounds just yet.
3 - In terminal, enter the following commands. You should see "x | y | z" after the checkpoint command... where x is 0 (database is ok), y is the number of modified pages, and z is the number of pages successfully committed to the database. y and z should be equal and much greater than 0. If the result is not as described, the database is probably screwed up and u were too late. Go back to step 1 and repeat.
$ su
# cd /data/data/com.android.providers.media/databases
# sqlite3 internal.db
> pragma wal_checkpoint(FULL);
> .exit
# exit
$ exit
4 - Trust the workaround and start configuring ur ringtones/sounds now... or reboot again and ensure the media store database stays fixed. I recommend the latter.
5 - 3 sir!
[/EDIT]
Greetings!
First, this message will be rather long, for which I apologize. I am providing headings that allow whomever is interested to skip to whatever is relevant to them.
About the device:
It is one of two Eken GC10X tablets, purchased from Micro Center a while back dirt cheap. The second one is 6000 miles away in Europe. . . .
It is currently running Android 4.2.2
Its firmware revision is v2.0patch1
Its kernel version is 3.4.39+, dated Friday, October 18th, 2013, at 18:11:40 CST
Its build number is wing_k70-eng 4.2.2 JDQ39 20131028 test-keys
It comes pre-rooted by default. All that needs to be done is to install a terminal program and pay attention to certain paths.
About me:
I have been messing with computers, programming, and operating systems since the time of "wood burning computers"
I know my hosts file from my fstab, I have run various flavors of both Linux and Windows in both client and server configurations, and I know that both man pages and a good search engine Are Your Friends. (which is how I came to be here!)
Issue:
Since this Eken tablet comes with a bare minimum of internal memory, I was researching ways to mitigate this. I found an article that mentioned a workaround:
Copy everything in root to a large external SD card
Transpose the settings for the internal and external memory in the /etc/vold.fstab file
Save and Reboot
The result of this is a tablet that - regardless of the presence or absence of any external SD card - always boots as if it had never been booted before, (returns to "first-boot / out-of-box" setup). Any installed apps are gone and the "internal" memory - which is about 1-2 gigs - shows absolutely full. In addition to all that, I cannot do anything with the ADB port since it requires setting the "USB Debugging" flag, which gets reset on reboot. (i.e. The ADB interface is not available.
Examining the vold.fstab shows that the original setup of that file has been returned after I did a nuke-and-reboot.
I can reboot and re-install a terminal program and advanced file manager. (X-plore is my favorite)
I see three possible solutions:
Find the reason why it's booting like this and fix it.
Find a compatible firmware release for this tablet and re-flash it - if possible - from an external SD card.[/INDENT]
Do some kind of "nandroid" backup from the other Eken GC10X tablet I have and copy it to this one. Unfortunately it's 6000 miles away and I won't be able to get to it until sometime after January 2019. In addition, I cannot access the device via the ADB port.
Research I have done:
gsmhosting's allwinner forums
This site claims to have a (ahem!), "modified" version of the firmware, which I have downloaded.
The androidmtk site
This site has the "PhoenixCard" software which alleges that it can be used to create external SD card images of firmware files that can:
Install firmware from the SD card to the device.
Allow you to run the firmware from the SD card to verify it. It should be noted that MalwareBytes flags the updater.exe file because it attempts to download from a known Trojan site. Renaming the extension, (exe.bad), solves that problem.
I have not tried re-flashing any firmware version, though I have tried running the firmware from SD, which doesn't work.
Can someone help me with suggestions on how to return this tablet to normal?
Thanks in advance for any help you can provide!
Solution:
I guess it's "umpteenth time's the charm!" :highfive:
Having done considerable research, (with everything pointing to an issue with the busybox file being in the wrong place), I decided to revisit this, did a little more digging and ultimately found a solution.
Since nothing irritates me more than someone posting "I fixed it!" without telling everyone else HOW they fixed it, here are the steps I used to solve this problem.
Please be careful. You will be mucking around with your tablet's/phone's root file system in ways that can be fatal if you're not paying attention. It's not that difficult but you DO have to PAY ATTENTION to what you're doing.
TO-DO:
Instead of copying the busybox file, it should really be a symlink to /sbin/busybox.
If anyone figures out a way to create a symlink in Android that actually works, I'd like to know.
Here it is:
Pre-requisites:
The device MUST be rooted for this to work. I cannot help you with advice on how to root individual devices. This Eken tablet comes rooted by default.
Download off-line from Android Archives, (using a different system), an early version of X-plore, which is an excellent file manager.
Load X-plore onto a thumb-drive or a micro-SD card, (I used a micro-SD), and then install the SD card / thumb drive into the tablet you're trying to fix.
Steps to solve the problem:
First, go to Settings => Security and enable "unknown sources"
Open your device's file manager
Find the copy of X-plore you downloaded, and tap it to begin the off-line installation process.
Once it installs, open it and go to the "configuration" menu. This is within the three-dot menu drop-down in the upper right-hand corner.
Select:
* (near the top) Show hidden files => select the check-box. (optional)
* Root Access => Superuser + mount writable (this allows you to change permissions to permit writing the root filesystem)
* (scroll down) Dark mode => select the check-box. (this is a personal preference; IMHO it makes it easier to read.)
* Exit configuration by using the "back" button or back arrow in the upper left corner.
* You should now see two columns representing two views of the device's file-system.
On the left side, open the "Root" filesystem, also labeled with a "/"
Scroll down and find the "/sbin" folder and open it by tapping on it.
* You may, or may not, see several folders and files. You are looking for the file "busybox"
* If you don't see it there, you may have to "find" it using the magnifying glass icon in the center row of icons.
* Open the "find" dialog and replace the "*.*" with "busybox" and then select "OK".
* (assuming you found it), tap at the right-hand edge of the row with the file-name to "select" it - a big check-mark will appear there.
Go to the right-hand side list now. Find and open:
* Root (/) like you did before.
* system
* bin
* At the top of that column, you should see a folder icon, followed by "/system/bin"
Look to see if there is a file named "busybox" there. (In my case, it was missing - which is the problem)
(assuming it's missing)
Collapse the "bin" folder by tapping on it - it might take a couple of taps.
Touch-and-hold the "bin" folder until a long list appears. Scroll down to the bottom of that list and select "permissions"
Within the permissions dialog, there are three columns: Read, Write, and Execute.
* There should be three selected boxes under "Read".
* There should be ONE selected box, the top one, under "Write"
* There should be three selected boxes under "Execute"
* Directly below the last box under "Read", the box labeled "Recursive" should NOT be selected.
* To the far right of "Recursive" should be a note that reads "Mode: 755"
Under the heading "Write", select the other two boxes so that all three are selected. The word "Mode" should now be followed by "777" Close the permissions dialog by selecting "OK".
Verify the following:
* The arrow at the top of the center column is pointing to the right. If it is not pointing to the right, tap it until it points toward the right-hand column.
* The file "busybox" on the left-hand pane has a check-mark next to it and no other files are selected.
* The "bin" folder on the right-hand side has been collapsed and is selected by being a darker black with NO check-mark.
* The top of that column shows the folder icon and "/system/bin" as the selected path.
Copy the "busybox" file into the /system/bin folder by doing the following:
* Tap the "copy" icon in the center column - it will look like two pieces of paper stacked together.
* Verify that the dialog that opens:
* Just below the top right it says "busybox" (the file you're copying)
* Under that, "Copy to"
* Under that, a folder icon and then "/system/bin".
* Under that, the selection "Move mode (delete source files) is NOT selected!
* Tap "OK" to copy the file to /system/bin. Once the copy is done, the dialog will close.
Tap "bin" on the right hand side to open it if it does not open by itself.
Verify that "busybox" appears in both the left and right hand panes.
Press and hold the "busybox" file until the list dialog re-appears.
* Select "permissions".
* Verify that all three "Read" permissions are set, only the top "Write" permission is set, and all three "Execute" permissions are set. (You may have to clear the bottom two "Write" check-boxes.)
* Verify the "Mode" is set to "755"
* Close the permissions dialog by tapping "OK"
Collapse the "bin" folder by tapping on it.
Long-press the "bin" folder, select "permissions", and set the permissions of the bin folder to "755" the way you did for the busybox file above.
Return to the "Configuration" menu by following the steps at the beginning and select "Superuser" or "Normal User" instead of "Superuser + mount writable" to prevent accidental changes in the future.
At this point, you should be able to close and re-open X-plore and verify that "busybox" actually exists within /system/bin. If it does, you can reboot and your should be good to go.
If it's not there, re-trace the steps I listed above, paying particular attention to the "Superuser" setting in "configuration" and the various file permissions.
If you're still having trouble, post a reply below and I will try to provide what help I can.
Thanks for your patience and I hope this helps others who were puzzling with this as long as I was.
