Some file need to set permissions if u edit or modify that file. Here I will show u how to set permissions on ur iphone using ifile. If u not yet have ifile, u can find in cydia.
Open ur ifile, then find ur file u want to set. Then touch blue narrow
Then scroll down u will see
– Read = 4
– Write = 2
– Execute = 1
If u want to set 775, so
* User : read,write,execute (4+2+1)
* Group = read,write,execute (4+2+1)
* World = read,execute (4+1).
Please leave ur comment
