Hey.
I am no stranger to Android hacking so I downloaded newest ROM for my Doogee DG280 (mt6582).
I flashed it, then backed up using SPFlashTool, processed using MTKDroidTools to mod boot and recovery
and from this new CWM I installed SuperSU update from ZIP file.
So far so good, BUT:
Once any application requests root (i.e. calls "su"), it loses the rights to READ from sdcard (actual or emulated, doesn't matter).
I am emphasising READ because common problem on Kitkat is that the apps cannot write on SD card, which is easily
fixed by the SDFix app (tried it - no help).
So basically, all my apps can now read/write sdcard, but once an app requests root access, from that moment it can only write
to the SD, but not read from it. This creates lots of ****ty situations - for example, I download a file to an SD card and want to
copy it to /system/media/audio using Total Commander. So I do this, Total Commander says it needs to remount the partition.
I click Yes, it requests the root, remounts the partition (success) to rw and then tries to copy the file from SD but because it now
has root, it has lost the rights to actually read the file I want to copy.
Funny thing is, when I connect USB debugging and use ADB, the ADB is rooted as well and it CAN read from the sd card.
So there is a workaround for me now to use Android terminal, connect to the adbd on localhost and execute all the commands
I need but that is VERY nasty and of course it only works for manual operations.
Many root apps use sdcard to store data, for example Lucky Patcher stores downloaded patches on SD card. But with this bug
it cannot.
Anyone encountered this problem? Any solutions?
Try flashing this zip in recovery. Remember to take a backup before flashing. Did wonders for my phone running on MTK6582 chipset on KK ROM.

no help
Unfortunately, didn't help. I examined the package and it does the same as SDFix app (which I already tried). But all these apps focus on giving write access to SD cards for ordinary apps.
I have a different problem - my apps actualy CAN read/write SD card right to the moment when they request root (call "su" binary). After that, they lose read access to the card.
Have you tried installing Busybox?
Maybe this helps: use SuperSU, disable the "mount namespace separation" option in SuperSU's settings. Reboot.

I have successfully configured my phone to install apps on the sd-card before. But because of some problems, I have to do a restore, and my latest back up file was before I partitioned my card and do the conversion stuffs. Now, I noticed that my free phone storage is filling up fast when installing apps. But using Ap2sd, I can see that the phone can detect my partition(304mb free out of 457mb to be exact). Do I have to re-run the conversion of extensions again? I'm pretty hesitant to do so until someone confirms that its needed since I did a nand restore.
Another thing - my sd card keeps on going to R/O privilege. I have to always use Root Explorer to change its permission state. Is this a common bug or what? Thanks
It's probably a corrupted a2sd script. Try another version of it and make sure that it is supported by your ROM.
it's true it will work, you will see
Hi Guys,
I have karbonn A15 android ICS(4.0.4) smartphone, its not rooted.
I want to move the app Data to my external sd card, i tried to move the data folder from the internal SD (android/data) to External SD (root folder), just to check whether it releases any memory in the storage section in phone settings. but the internal storage was same, there was no change, can anyone tell me where does the app data resides in the internal memory, its fine if i can move app data manually to the external sd card.
I also want some clarification on below questions:
1. Also i want to know whether there is any risk rooting phone like (Bricking Phone), as i have bricked my previous Galaxy Ace when i rooted and used ROM manager.
2. Also i have heard about Folder Binding app which automatically transfers App Data to External Sd Card, is there any risk of bricking phone.
3. Whats the easiest method to root Karbonn A15 phone, i am not that tech savvy, so easiest method would be grateful in rooting device.
My concern is just to move App Data to External Sd Card, because i have some app whose Data increase very frequently (E.g: FireFox app).
Answers to this would be really appreciated.

Rooting:
here are the steps
the driver files are included on the phone internal card called pcdrivers.zip. you can connect the usb mount the internal usb storage and copy the file to your pc. if you face any problems you can download the file from here
1. Enable USB Debugging -> Under SETTINGS -> DEVELOPER OPTIONS
2. Install the drivers for the phone.
3. download "Android Root Unlock" from sourceforge.net and extract it to your Disktop
4. navigate to the above folder and run the batch file ICS_Root_Unlocker.bat
the batch file will reboot your phone a couple of times and will wait with a message "Press Any Key to continue"
IMPORTANT NOTE : if you PC is saying "PRESS ANY KEY" note if your phone is on or rebooting....
if it is Rebooting, wait for it to start before pressing a key
5. After a couple of boots the phone will be rooted
6. verify that the Root is complete by observing a "Superuser" shortcut in the application list
Moving Apps:
Once rooted, download Folder Mount From the Play Store
- Once installed, open FolderMount and grant superuser access when asked.
- In FolderMount, you have the options to:
- Name your folder (IE: "Generic Game 1")
- Select the "Source" Folder (the one on your local storage)
- Select the "Destination" Folder (the one on your SD Card)
When you enter these details, it will then move them to your SD Card!
I highly recomend FolderMount Pro, because it also shows you filesizes when browsing.
Common Locations of Large Files:
Two common locations for games (IE: Gameloft games, EA Games, etc.)
Android/data
Android/obb
I know it's not the easiest process ever, but hopefully I've explained it enough to get people started.

Is there any method/app that can provide a similar functionality without rooting the phone? I tried rooting my Karbonn A21 without success and do not really want to brick it?
Also is there any way of backing up the phone and app data before rooting? Will the existing apps and data be wiped out by rooting?
Thanks in advance.

You can use App2SD but you have to check if your device is compatible or not.
you can use Kies to backup your apps, settings, etc.

foldermount
so quick question, i transferred games to external sd, worked fine and all, but after a while my games asked me to download the files again, anyone know a solution?
I m using foldermount but there is write error mention that was unable to write into the external sdcard caused by a permission issue where normal apps are not able to write anything into storage/ext_sd. What should I do next to solve this problem? Attempt to recover using the apps not solving it.
This is what i mean.
Moving app Data to External SD card
in particular the movement of android apps data from internal memory to SD card is a simple process, but the problem with these issues is your smartphone is to be a latest version like 4.3 version.
Idea
Can I move the game folders from Internal Storage: Android/data -> SD card: Android/data, will it work on non rooted phone? In the Data folder on the SD card are partition of some apps and they work just fine. Same with folder "obb".
moving apps data and obb to External sdcard.
I recommend using an app called folder mount. ..it needs root but it's as easy as fishing in a barrel. .. I am using It and it works fine... and now you have a clear space in your internal storage.
Hey, I followed above instructions and my phone Samsung S5 6.0.1 successfully rooted, but now I've entered into an endless restarting loop.
Please help what's the problem might be?
ABOUT
This is a solution for the dreaded warning about running low on internal memory on 2011 Xperia phones. My own Xperia Mini Pro has only 420MB of internal storage and this fills up quickly when installing apps. In this post I provide instructions and scripts to use the external SD card to extend the available internal storage, a so called “int2ext” solution which there are many flavours of.
The goal has been to solve the storage problem while at the same doing as small changes as possible to the system as possible (not unlocking bootloader, not installing custom recovery, etc).
Note that when the SD card is used to extend internal storage you should never power on the phone without the SD card inserted. Failing that you will probably need to factory reset and start over with the installation.
The whole 2011 Xperia range should be compatible, maybe other devices too.
BACKGROUND
After trying (and failing) with a number of the other solutions for enlarging internal storage with the external SD card, I've made my own solution that works on the Xperia Mini Pro (XMP) stock ICS ROM. In the second post I describe some properties of my implementation that may count as advantages for some, YMMV though.
COMPARED TO OTHER SOLUTIONS
See second post for technical description.
PREREQUISITES
Sony-Ericsson stock ICS ROM installed on your phone (you don’t need unlocked bootloader, recovery or any other mods)
Remove any other similar apps or tweaks (Link2SD, Apps2SD, INT2EXT etc) as they may interfere with this implementation. The installation script will abort if any of these are found.
USB Debugging enabled in your phone’s Developer settings.
Micro-SD card to install in the phone’s SD slot.
Cydia Impactor (optional)
Download from http://www.cydiaimpactor.com/.
Flashtool (optional)
Download from http://www.flashtool.net/. I have used version 0.9.18.6 which worked fine for the XMP while 0.9.20.0 had some problems. I have been told this has been fixed in 0.9.21.0 but have not verified it myself.
DOWNLOAD SCRIPTS
You find zip files as attachments at the bottom of this post.
INSTALLING
Check current firmware CDA (optional)
It is good to have a record of the exact firmware variant and version currently installed in case you need to flash back the stock ROM.
Go to the right place in the phone’s service menu:
open Phone Dialer
dial the secret code appropriate for your phone (for XMP it is *#*#7378423#*#*)
go into Service Info
go into Software Info
Note down the CDA number shown under the Customization Number heading
(see also http://www.hanfei.name/what-is-cust...xperia-device-and-how-to-view-or-find-it.html)
Partition your SD card
Your SD card should be partitioned as an MBR disk with (at least) two primary partitions:
The first partition should be formatted as FAT32 and will become your new (and smaller) SD card storage that you seen when connecting the phone to a computer.
The second partition should be formatted as Linux Ext2 and will become your extended internal storage.
You can have more partitions after these but these scripts will only care about the first two. I use a 16GB SD card and split even with 8GB to each partition.
There are many ways to perform the partitioning; I put the card in the SD slot on my computer and use the Minitool Partition Wizard Free Edition (http://www.minitool.com/partition-manager/partition-wizard-home.html) under Windows. For kicks you can install it using the Chocolatey auto-installer (https://chocolatey.org/packages/partitionwizard) if you like. You have more info about Minitool and other tools here:
http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning
Note 1: Remember to set that partitions should be primary as some tools may default to logical and not primary partitions.
Note 2: You probably want to copy all your SD card files to your computer while partitioning and formatting, and copy them back after, as all data will be erased on the SD card.
Prepare your phone
Insert the partitioned SD card.
Enable USB debugging in Developer settings.
Have a USB cable ready for connecting between your phone and computer.
Root
If you have already rooted you can skip this step. All you need is the su binary on the system - you don't need the SuperSU app installed.
I use Cydia Impactor to root:
connect phone
select "# drop SuperSU su to /system/xbin/su"
click Start
(see also http://forum.xda-developers.com/showthread.php?t=2399464)
You can verify that it worked by opening a root shell.
I do this from Cydia Impactor:
menu Device > Open Shell…
type “su” at the prompt
type “id”
“uid=0(root)” should be shown
Update Busybox
The existing Busybox on the XMP is too old and will not support the way directories are mounted here. I have used Busybox 1.22.1 so I highly recommend that you install this version using the procedure below. If you already have this or a higher version installed you can skip this step but please verify that you have all the needed applets in your Busybox binary by checking against all the busybox aliases at the top of my scripts.
I use Flashtool to upgrade Busybox:
connect phone
Device menu > Install busybox
choose version 1.22.1
Install init.d support
The stock ROM does not have init.d support so we need to add it. If you have already added init.d support using some other software then you can skip this step.
Unpack the init.d.mikewse-<nn>.zip file to a directory (f ex init.d.mikewse) on your SD card.
Open a root shell on the phone using Cydia Impactor:
menu Device > Open Shell…
su
Install by running the install script:
Code:
sh /sdcard/init.d.mikewse/install.sh
You can verify the installation by checking the existence of the init.d directory:
Code:
ls -d /system/etc/init.d
The init.d function will be active after the next reboot and you can see messages from it in the kernel log:
Code:
dmesg | grep init.d
Install int2ext support
Unpack the int2ext.mikewse-<nn>.zip file to a directory (f ex int2ext.mikewse) on your SD card.
Open a root shell on the phone using Cydia Impactor:
menu Device > Open Shell…
su
Install by running the install script:
Code:
sh /sdcard/int2ext.mikewse/install.sh
You can verify the installation by checking the existence of the int2ext boot file:
Code:
ls /system/etc/init.d/40int2ext
The int2ext function will be active after the next reboot and you can see messages from it in the kernel log:
Code:
dmesg | grep int2ext
You should also be able to see the new larger size of your storage in the Storage menu of system settings.
Tweak what’s put on the SD card
The default int2ext script is set up with a good compromise between what files are delegated to the SD card vs are kept in the original location in internal storage. Apk files and app data are delegated to the SD card while unpacked app code (dalvik-cache) is kept on internal storage for speed and availability.
If you are installing a large number of apps your dalvik-cache may grow too large for internal storage. You can check how much it has filled up from a root shell:
Code:
df /mnt/int-stor
and also see how much of this is due to files in dalvik-cache:
Code:
du -s /mnt/int-stor/dalvik-cache
If you are hitting the limit then you can configure delegation of dalvik-cache to the SD card:
open a text editor with the 40int2ext file that you unzipped to the SD card in the int2ext.mikewse directory
edit the line
Code:
EXTDIRS="app app-private data"
so it becomes
Code:
EXTDIRS="app app-private data dalvik-cache"
then reinstall int2ext by running the install script again
REFLASH STOCK ROM
If you want to start from fresh or need to recover from some failure in the installation then you can flash back the stock ROM using Flashtool.
First let Flashtool download and assemble the appropriate stock ROM for you:
click XperiFirm icon in toolbar (furthest to right)
select your phone model
select the appropriate CDA (collected at the beginning of this post)
click the release info in the right pane to start download
Then flash it to the phone:
click Flash icon in toolbar (furthest to left)
choose Flashmode
follow instructions (for XMP press Volume Down)
If you have any questions or problems regarding Flashtool there are lots of threads on XDA were you can find solutions about drivers etc.

DEVELOPER INFO
If you publish a modified version of these scripts or include them in a ROM then please give credit by linking to this thread.
GOALS AND TECHNICAL DESCRIPTION
Here's a few thoughts that have influenced the implementation:
Working for autostart apps, widgets etc
I have seen mentions that Link2SD and others have problems with redirecting widgets and other types of early-start apps. I have not seen this myself and suspect this may have to do with other factors (f ex doing install steps in the wrong sequence may bork your installed apps).
Anyway, I have verified that my solution works with all apps (early-start, system and downloaded) on the XMP.
No extra bells and whistles
Many of the available solutions add extra "nice to have" features to make scripts more universal or maybe optimize speed on some devices. I actually ran into problems with some of these optimizations on the XMP so deciced to only perform what is exactly necessary on the XMP and nothing else. This script only performs mounting of partitions and moving of files therein.
Mount the /data base directory on external SD card
Several other solutions keep /data mounted on internal storage and just redirects /data/app and others to the SD card. That is good in theory but at least on the XMP this causes you to still get warnings that storage is full as the phone detects that your apps take up more space than fits in /data. With my solution the phone will see the enlarged /data partition and will f ex report this correctly in the Storage menu.
Keep most /data subdirs uninterrupted on internal storage
There are some critical directories on /data that should be available without interruption from boot and onwards. Having these come and go during startup can lead to different problems such as signal loss (correlated to /data/radio). To avoid surprises this script only keeps the typical hogger directories app, app-private and data on the SD card and rebinds everything else back to internal storage in one rbind-mount command that eliminates interruption of these subdirs.
If you want you can customize which /data subdirectories are used on the SD card by simply editing the EXTDIRS variable in the 40int2ext script. Existing files will be moved accordingly on the next boot.
Simple install script run from terminal instead of flashing from recovery
Stock ROM doesn't have recovery with flash function so I have instead made simple install scripts that you run from the Android shell.
Follow standard principles
Like several other solutions this script hooks the debuggerd binary as that seem to be triggered earliest during startup. I also look for installations of other solutions and will abort if any are found as that could lead to problems.
Naming is kept similar to other solutions apart from the strange habit to use "sd-ext" as the name for internal storage. In my implementation internal storage is mounted to /mnt/int-stor and the external SD card to /mnt/sd-ext.
CHANGE LOG
1.0 (2016-05-03)
Inital version
I spent a lot of time on this and finally reaching out for help.
None of my apps are able to access storage (internal sd card) for writing, even after granting permission manually or when prompted.
Setup: flashed with TWRP 2.7.1: aicp_klimtwifi_n-12.1-NIGHTLY_20171121.zip (which is Android 7.1) and open_gapps-arm-7.1-stock-20171123.zip. also used CFautoroot to gain root access (successfully).
But all downloads from Chrome fail because of unknown errors. Trying to create a folder inside Download in File Manager results in an error saying this requires elevated access. All these apps have storage permissions.
I can install new apps from play store. In the terminal as root, I can see that everything in /storage/sdcard0 is owned by root/sdcard_rw and has drwxrwx--x access bits.
Trying to fix file system permission in TRWP resulted in a nasty boot loop and I had to retrace my steps.
Not quite sure how to proceed. I'm not worried about data loss. For instance, I would happily use TRWP to reformat internal storage (if there is such an option), but I'm getting worried of digging a deeper and deeper hole for myself.
I can copy/move files from internal storage to SD Card if I use the built-in file manager. However, if I use any 3rd party file manager, the operation will fail. It is as though the SD Card is read-only. I can copy from the SD Card to internal storage just fine.
I've tried ES File Explorer, File Manager Pro, Solid Explorer and they all failed. I've given grants to write to the root of SD-Card. Does anyone have any idea how to fix this?
Try with a real file manager like

Mixplorer works great. Root Explorer also works.
Thank you for your recommendation!
I really don't get it. At first, nothing works. Then when I install Root Explorer and grant storage access to the root of the SD-card, it immediately works.
Then I tried MiXplorer and it also works. Now when I return to Solid Explorer and it is working now.
What's going on? Does Root Explorer unlock something which makes it "click"? I don't get it at all. I only hope it is reliable in the long run and not switching "on" and "off" randomly.

Root Explorer has been the ultimate for me. I bought the paid version when it first came out years ago. It always acomplishes whatever task I need it to do.
Not Working
Not working for me.. I am using Honor V10... recently, I installed the android 10 (EMUI 10) update via ota (over the air). I have tried Root Explorer, ES file manager pro, but no file manager is able to write to external card except default file manager (which is pre installed)
PS: My phone is not rooted.

I still have the same problem...
I have a new P30 Pro and Nano SD card Just arrived.
I can write (and read) the card by external reader, connecting the phone via USB to a PC, etc. etc.
But when the card is on the phone I can only use Heawei file manager!!!
I have enable the option allow apps to write to external card.
I've just update on EMUI 10 build 10.0.0186
I can't beleive I tried a lot file manager and also some alternative app like quickpic and no one works good!!!!
Fix the problem...
After enable the option allow apps to write to external card, I tried to disable developer settings.
Also tried to active some app I've disable before... 2 app, default browser and HiCare!
That's all and now I have no problem writing Nano SD card with all of my app!!!
I also rebbot the phone sveral time...

I enabled the default browser and the HiCare app (actually they were not disabled, so I just opened them to complete their setup) but this did not help either.
I even formatted the memory card (using my phone "format card" option) and then reset my phone to factory defaults and set it up again from the beginning without restoring backups.
I still have not found a solution to thus issue, though.
Any ideas anyone?

Hi there.
I have the exact same problem.
None of those steps helped me
I tried installing every single Root Explorer there is in the Play Store, but none worked.
Which one of the Root Explorer apps that we can find on Play Store did the trick for you ?

I had to instal FX file commander to get SD card write permission....I can't make it stick, every time I reboot I have to reset the sd card write permission.
I have similar problems relating to this thread on my mate 20 pro after updating to Android 10 (EMUI 10). I've tried all the methods mentioned here and it worked briefly before restarting the phone. After restarting the phone, it went back to being unable to copy files to External Storage.
I noticed that i was able to delete and rename files on the external storage but i just can't seem to copy anything into it.
I can copy files from the external card to internal storage but not the other way around.
Tried using MiXplorer, the only way i can copy files into the external card is by this method:
i copied the file and it shows error, but there's an image of the file created on the external card with 0 kb. Then i overwrite the file and replacing the '0 kb' file and it worked. And another method to just to use the built-in file manager which is a pain to use and the UI are crappy.
It was a lengthy method and therefore I decided to downgrade to Android 9 for now.
I also noticed i can't change the download directory of my Ttorrent app to any folder of my choice in external storage.
anyone can suggest a better method to overwrite this external drive issue? Thanks in advanced.

This this the "official" reply at the Huawei forums:
https://consumer.huawei.com/en/comm...-disabled-for-3rd-party-apps-!/topicId_90489/
Now, what I've come to notice is the following:
- All Huawei and Google apps I have tried, do have access to the memory card (e.g. Google Maps is allowed to save its offline maps on the SD card, the same for Google News and the articles it downloads)
- Some 3rd party apps do have access. E.g. Here We Go maps can save its maps on the external card. ASR Voice Recorder can save its recordings to a specific memory card folder, the one that is automatically created -on the card- by the app when it is installed on the phone. Maybe there are other app that we will find they can, too.
- So it seems that the rule is not general, as Huawei implies at that thread I have posted above.
My biggest concern was that MixPlorer has now limited use, and this is kind of sad as it was my favorite explorer.
Huawei Files manager is not bad, it's actually quite OK, but it bothers me that you cannot add 3rd party clouds on it. If it had that option I would be happy with it. I like it that it has that "favorites" option. For now I have created a folder "My Archives" on the internal memory and I initially save almost everything there (e.g. my Nova Launcher backups). Then I use Huawei Files manager to move them to the external memory card on the folders I want.

Hey that's a good idea of creating a temp folder on your internal drive before using Huawei file manager to transfer everything out to your external card. However it requires additional steps to get it done but it's a good idea nonetheless. Thanks for that suggestion. For me i'm so used to be using solid explorer to do all my file operations as it has google drive integration which makes it easy n fast to transfer between drives. So i guess my best bet is to downgrade to android 9, it's just much more comfortable to work with and in my opinion, android 10 is not that big of a deal and not much substantial changes anyway. Hehe.
Every reboot I always have this facing problem!
Sometime I must reboot because my smartphone switch off for low battery....
When I reboot try to disable and re-enable the special option in developer menù, also try to uninstall and after install again the memory card (from setup/memory menù).
After that try to copy some file to memory card with default file manager an default Gallery...
Sometimes it is enough sometimes I have to try more and more... But after several time it works!
Xplore
Try xplore by lonely cat games. It's working on my mate 20 pro and survived reboots.
