This solution is based on the experience with some HTC and Nexus devices, however it will work on any device running Android Lollipop or newer/older Android OS with SELinux (Security-Enhanced Linux) kernel security module.
What's the problem? Sometimes you might not be able to access the content of the internal userdata memory, also known as "virtual SD card" - located as /data/media/0 on the userdata partition. The "bad" workaround is to boot the device in a recovery mode and gain the access to all files from there, but this doesn't solve the problem at all.
Repair Process
Note: root required!
Note: root required!
- Download this mini-sdk package and extract it to c:\mini-sdk
- Connect your device to the PC
- Start up the device normally, wait until system is fully loaded
- Open a command prompt on the PC (cmd.exe), type and confirm each command with ENTER:
- cd /d c:\mini-sdk
- adb shell
- su
- restorecon -FR /data/media/0
- exit
What's going to happen? Restorecon is a program used to restore file(s) default SELinux security contexts. It can be run at any time to correct errors or to add support for new policy. With a corrected SELinux security context for the /data/media/0 you will be able to access the content of the virtual SD card again.
