Hey,
my Ainol Novo 9 Spark can't write on my extSD/USB devices. I tried to format/remount but nothing helps. The SD Card is working fine in my Galaxy Note

It's kinda easy to fix just open /etc/permissions/platform.xml find:
Code:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_rw" />
[B] <group gid="media_rw" />[/B]
</permission>
and add the bold line
Thanks a lot! It worked
First of all, I would like to thank poolmaker who had a tutorial over at the Xperia Z1 forum. So go on over and give him thanks!
First you must be rooted. Second must have a file explorer. I personally use ES File Explorer so the steps below will be covering that file explorer.
Open ES File Explorer.
Open the Tools Menu.
Make sure Root Explorer is turned on and long press over the name "Root Explorer".
A sub-menu pops up, select Mount R/W. (if you don't do this the changes you make will not stick.) The next menu that pops up, you want to make /system RW by selecting the radio button.
You then want to navigate to /system/etc/permissions.
Scroll down and find platform.xml and make a copy of it and save it somewhere.
Open the original file with ES Note Editor and then press the menu (the 3 vertical dots) to edit.
Make the following changes
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
<permission name="android.permission.WRITE_MEDIA_STORAGE" >
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>

Save the changes you make.
Before you exit, check the permissions of the edited platform.xml. They should be (rw-/r–/r–).
Reboot your phone and enjoy being able to download/write/copy to your external SD card again.
This is a great tutorial to do it manually.
However you can also just install this app https://play.google.com/store/apps/details?id=nextapp.sdfix
Install, run it and uninstall.

Of course that is always an option, there are actually a few apps on the market that do this. I just thought since it is xda, people might want to do it manually.

I went through the whole tutorial, it worked great. Then I scrolled down and noticed there was an app, oh well. Thanks for the write-up!
Please help. Can anyone give me a copy of their original platform.xml? Seems like I messed up mine. Can't find my back up. Help would be greatly appreciated. Thanks in advance.
I followed the steps in the first post and after I rebooted, messages keep popping up saying this and that failed to start and now I can't even use the phone because they pop up every 3 seconds.. I also can't see any files through a file browser or on the computer. I have a copy of my platform file on the phone but no way to get to it because no files show up in the file explorer. Any ideas? My phone is basically useless right now.

I am so sorry for what is most likely a stupid question, but what is advantage of this? Does this address the issue of 4.4.x where we can't store our app data on our micro sd cards? Thanks in the advance for the help
What is the purpose of the mount r/w option?
I think I understand this but when I selected Root on, I was able to copy and overwrite and rename system files like SystemUI.apk. I did not have mount RW for the /system folder. So what exactly does the mounting do?
Bob
The app didn't work for me, but this manual write up did it!
Thanks saved me from having to install a new rom.
Thank you for this tutorial!!!

That's weird. It's working for me. Hopefully this works for you. Just copy and paste into Notepad++ or equivalent and name it platform.xml I've also attached it, just remove the .txt extension.

There's also an Xposed module for this too: http://forum.xda-developers.com/xposed/modules/kitkat-sd-card-access-t2790992 . A "semi-manual" option, if you will. I did both the manual run-through and then tried the Xposed mod to confirm they both made the same edit and both worked.
this did not work me i did this and went into dolphin browser on my galaxy tab 4 8.0 sm-t330nu and tried to download a picture and got that popup saying i cant do it why?

Hi _eroz
Just to say Thank you.
PLus I discovered the ES Task, and I had to root my phone. I feel that I 'll play with it even more, like changing rom...
I made a huge mistake. I edited the platform.xml cause i read that after i could use apps on sd card, but i made a mistake and now i cant reach my internal and external card neither, i cant reach google play. I tried to factory reset it, but not helped, just my root gone. After i succeed to root it again, but i cant edit again with ES file explorer cause its need SuperSU pro(before not needed) so i cant restore it. Please help me
Now i finally can change the file, but i havent got the original settings
Anyone can link yours platform.xml file? My settings was a similar kitkat file, but now its looks like this:
name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
</permission>
<permission name="android.permission.WRITE_MEDIA_STORAGE" >
<group gid="media_rw" />
</permission>
The group gid was different there, but i dont know what was them
Hello guys! I'm having some problems with my Z2! The system and Stock Sony apps won't recognize my SDCard, but I can access it through Root Explorer and ZArchiver.
The part of my Permission.xml file regarding external storage is as follows
<permission name="android.permission.READ_EXTERNAL_STORAGE">
<group gid="sdcard_r"/>
</permission>
<permission name="android.permission.WRITE_EXTERNAL_STORAGE">
<group gid="sdcard_r"/>
<group gid="sdcard_rw"/>
<group gid="media_rw"/>
</permission>
<permission name="android.permission.ACCESS_ALL_EXTERNAL_STORAGE">
<group gid="sdcard_r"/>
<group gid="sdcard_rw"/>
<group gid="sdcard_all"/>
</permission>
<permission name="android.permission.WRITE_MEDIA_STORAGE">
<group gid="media_rw"/>
</permission>
Is there something wrong?
I'm running rooted stock 5.1.1 firmware (23.4.A.1.232) and locked bootloader.
Update: If I remove it and reinsert while the phone is on, everything comes back to normal. But, after a restart, the problem happens again.
bump!
yes it happen to me too.. by the way..i reflash stock rom and root again.. please beware do not put your memory card out before you unmount it. .. :fingers-crossed::fingers-crossed::fingers-crossed:sorry for my english.. i hope you understand.
I have a phone with android 4.4.2 and want to edit the permissions of the external storage, but not sure what should i change.
Almost all apps seem to exclusively focus on internal storage, to the point they ignore external storage completely, and that's what i want to change.
On platform.xml right now, the READ_EXTERNAL_STORAGE says:
<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
</permission>

What would change if if it said this instead? :
<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="media_rw" />
<group gid="sdcard_all" />
</permission>
Click to expand...
Click to collapse
Or how can i give apps total permission for the external storage.
