Had same problem to. Chmod things didnt fix it for me
So i wrote a bat file that fix it everytime I want to run on Android.
I just save the bat and then I drag the folder of android in the bat file.
Here is the script.
If [%*]== Echo No Folder entered&Goto:EOF
If NOT Exist "%*" Echo This folder %* does not exist&Goto:EOF
If Exist "%*\Private" (
For /D %%I In (*) Do (
If /I Not "%%I"=="Private" cacls "%%I" /t /e /c /g Everyone:w&cacls "%%I" /t /e /c /g Everyone:c
) Else (
cacls "%*" /t /e /c /g Everyone:w
cacls "%*" /t /e /c /g Everyone:c
Hope it helps Stupid solution but it works.
