[FIX] SD Card Write Restriction ALL Firmwares and Models topic


Hi!
This is my first thread and I just wanted to share this information about SD card write restriction on Samsung devices with you.
I found a solution when I was having a problem of my own.

Description of problem:



I have a Galaxy Tab 4 10.1 SM-T535 running Lollipop 5.0.2 but this problem also happened while on KitKat 4.4.2. So, my navigation app downloads maps from its server, it's normal, right? And it gives me choice whether I want to download it to the internal or external storage, that's normal too. But just as it finished downloading it'd say that it can't load the map from external memory 'cause... "f*** you"...? THAT is NOT cool. And after some research I found this solution.


Solution:
Fixing this problem can be easily done if you have root access. Here’s how you can do it (Please be aware that you’re performing these changes on your own risk!):
1. Make sure that you have root access
2. Perform a NANDROID backup to be completely safe
3. Use a root-enabled file manager (like the paid version of Root Explorer, you can get it from... many sources ;) ) and navigate to /system/etc/permissions
4. Edit platform.xml and find “WRITE_EXTERNAL_STORAGE“
5. Add an additional group definition for this permission: <group gid=”media_rw” />
6. Save the changes and restart your device
You are now able to write on your external SD card again!!! :D

I hope I helped someone with this thread.
GOOD LUCK!
