Lightbulb [TUTORIAL] How to write/copy/download to the external sd card

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.
  1. Open ES File Explorer.
  2. Open the Tools Menu.
  3. Make sure Root Explorer is turned on and long press over the name "Root Explorer".
  4. 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.
  5. You then want to navigate to /system/etc/permissions.
  6. Scroll down and find platform.xml and make a copy of it and save it somewhere.
  7. Open the original file with ES Note Editor and then press the menu (the 3 vertical dots) to edit.
  8. Make the following changes
    Quote:
    <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>
  9. Save the changes you make.
  10. Before you exit, check the permissions of the edited platform.xml. They should be (rw-/r/r).
  11. Reboot your phone and enjoy being able to download/write/copy to your external SD card again.

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 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

Default 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?
