Hi,
Apologies if in wrong section, but I have a query about updating the platform.xml file on my Samsung Galaxy Trend GT-S7580
to allow rw access to the external sd card.
I have rooted the phone and mounted the file system, via Mount /system (rw/ro) app. (check root and Titanium backup confirm it as rooted)
I can navigate to and update/save the platform.xml file, however whenever I restart the phone the file reverts to its original and my changed are lost.
Before restarting I was able to create a new folder etc on the sxt sd card, but again after restarting the folder seemed to be gone too!
Is there anything I am doing wrong, or additional steps I am missing out on?
Any help is much appreciated
Update .... turns out its the microSD card that is the problem. Cant seen to write or delete from it even though its not read only.
Got a new card and hey presto, worked fine

Hello, I have a question. I have the Samsung galaxy ace root and the root explorer I can see the files but the problem is that I have a problem with the sd card.
Explaining the root problem is that I open explorer and I get the root folder and there I give app data and then and there I get all the apps installed on the internal card and cell phone so I give the app and I can give install message so that if I give to see all your arxibos will I see, because I want to do the same thing but in the applications installed on the sd card is all that installed him stan to see how the d internal memory but the memory externally. Not if I explain here is better:
when I get into /data/app

imageshack.us/photo/my-images/842/37418692.jpg/

and when I'm in /mnt/sdcard
imageshack.us/photo/my-images/204/24011522.jpg/
The purpose of this is that in / mnt / sdcard no data / app so I can not give the application to see as before in / data / app so you can see the configuration files of the game
Even in the pc let me.
PS: the big problem is that the file is read-only and even changing the permissions and putting it all clicked not even let me delete or modify files in that folder or glue or anything.
Let's see if anyone can answer me. thanks
I just has my USCC Galaxy S3 replaced under warranty. To save my internal SD files, I used an ADB pull /storage/sdcard0 in recovery. When I got the new phone rooted and CM10 installed, I booted to recovery and used an ADB push to restore the files. The files all ended back on the SD card, but now my apps cannot write to the folders on the SD card. The permissions are set to 644, and I cannot change them. I have tried with chmod and through file managers to change to 777, and although they claim success, the permissions stay 644. I'm unsure where to go from here, but I really would like to keep these files on my device. Any ideas on how to fix these permissions? Thanks!
Try copying/moving files around using the phone's file manager, & see if the changes stick. Also try "adb shell" -> "su", and change permissions that way, & see if it sticks.
Make sure you have an updated busybox.
Well, I tried moving them with file manager, su and updated busybox, changing permissions, and then I finally decided to go into recovery, pull, and format /sdcard. Once I did that, my apps were able to use the card again. I then was able to copy over the files via usb mount to windows. This seems to be working so far.
Thanks!
Hello all!
I'm not sure if this has come up yet with anybody here, and I didn't see a post referencing it. I just rooted my Shield Tablet and
installed Titanium Backup. When I went to the preferences to change the backup folder to my external SD card it told me that
it was read-only and wouldn't allow me to use it at all.
I just want to save anybody else in a similar situation some time. I'm unable to link things currently but all the credit goes to

1. Using a root-enabled file manager, navigate to /system/etc/permissions
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...<group gid="media_rw" />
4. Save the changes to the file.
5. Restart.

I would also add that you must mount the partition as R/W first or you will not be able to save the edit.

I had some issues with the SD card as well. Now that you have root access go to the play store and install SD fix and netapp sd fix. Install them both and run them. I started with netapp SD fix and it said it worked but only certain apps got the right permissions. After i also installed the SD fix (kitkat) Both of them said status of good to go. And now all apps worked with the SD card. Be sure to also use the Root checker app to verify that your root is sticking.
If you have your Shield or Shield Tablet rooted, I would suggest installing Xposed Framework and then installing the "HandleExternalStorage" module. That will give you back read/write access to external storage. I'm able to read/write to my 128GB Micro SD in my Shield and Shield Tablet and to my 64GB card in a memory card reader using an OTG cable with no issues.

Just stumbled upon this post and appreciate the information! Have an S5 and was wondering why I couldn't use my extSDcard for backups. Seems ridiculous to be limited to internal storage... One simple line of code and all is working flawlessly.
I've got 12S, rooted and all things seem to work well. I have a singular SD card question:
When I boot into system, I can read and write to the SD card just fine. There is one exception, I am unable to copy/see/read my TWRP backups with any app, and when I plug in my phone, which is booted into system/desktop, Android File Transfer sees all things on my SD card just fine, except TWRP backups. Root explorer is the same, it sees all files, etc on the SD card, except for the TWRP backups.
I can boot into recovery and Android File Transfer will see the backups fine, and I can copy from there. I'd like to be able to work with them while booted into system. I have used the TWRP SD fix, which does not change anything.
I am using Selinux to soften permissions. When I try and use Root Explorer or the like, to fully open up the permission of the TWRP directory or backups, I get a "Permissions Change Failed".
Any help is appreciated.
So its a long story guys.
I am Iman. And i have a samsung galaxy star pro ( i know its old, but i just need the solution, not advices to buy a new phone)
Yesterday i rooted my samsung galaxy star pro, with pc kingoroot pc software. And it was sucessfully rooted. Today I installed, link2sd, RoesoftRamExpander and FOLDERMOUNT in my phone.
Ok so when i was using folder mount when i opened the app it gave an error type of thing that a faculty error has came and it will have to do something to the sdcard (internal storage sd card) and it also said that i will create a backup as well.
I just clicked ok, and then using folder mount, i didnt found it effective because all the data was in KB's so i uninstalled folder mount. Now when i opened gallery it said that data is low than 100 mb delete some files. I rushed to settings>storage and saw the Phone memory was 4 Gb/4GB full. (my phone even doesnt supports apps2sd so i cant change default storage to ext sd card)
ok so now i opened es file explorer and the sd card was empty. I opened up /device and searched a file called sdcard.backup and it was there, which means that i have the backup. Now how can i restore it please??????????????? I really need to restore it. if theres an app to do it than tell me , i have also gone in foldermount settings but found nothing there. I can install apps, because the apps go to device/system>data
