Exploring SDCard0 via the native File Manager or ES Explorer yields 'empty folder'. The phone believes the files are there still, as evidenced by the Settings/Storage info displayed, which shows accurately the amount of space remaining. But the files are not accessible.
On attempting to browse the SDCard0 storage using Droid Over Wifi, there are two error messages
Error!*(12:58:40) Error reading directory: /storage/sdcard0
Error!*(12:59:8) DroidOverWifi does not have permissions to read directory: /storage/sdcard0/Download.
I've been running low on memory to install new apps, and hoped to reallocate some data to external storage. To that end I installed Towelroot, Link2SD, a root uninstaller and SuperSU. I used Towelroot to access normally inaccessible files in ES Explorer, but made no changes. I didn't change any of the partitioning or add or delete any files.
There is an annoying Carrier bootup logo that I hoped to uninstall, but this uninstall was unsuccessful.
The phone isn't writing to internal storage anymore either. It wasn't possible to access Viber images that are/were stored there, or to take and save a screenshot using the simultaneous power/volume down buttons..
Running Android 4.3 on a Huawei Phone.
How do I get the 'permissions' back for access to SDCard0 as per usual?
