I deleted mixer patchs files

[tekinsan]

Hi, i was deleted my mixer_ paths.xml , mixer_paths_i2s.xml and mixer_paths_tasha.xml, please dont ask me why, it was big mistake.
my phone is rooted but i cant past new mixer files too in etc folder. i was found a mixer_paths.xml ( and just this can be pasted on etc but i was delete codes inside) now i cant change nothing( not working copy paste and i cant changing permission settings)
How can i fix this ?
