Nexus 5 SDCARD files are not writable from PC USB I was trying to update my TWRP thought Google play store TWRP app. It did apply some sdcard pactch, which I later removed it. 

But after that when ever I try to access files of my nexus 5 storage I cant write or delete stuff.

Below image you can see my phone is getting detected, But I cant copy paste music in my phone.



Also, if I try to access my sdcard from Root file manager it comes empty,

I have even tried uninstalling MTP drivers and installed again. But it seems some File permission issue on my sdcard itself !!
It was sdcard permission issue created by TWRP Manager app from google play store.

I had to flashed 5.0 and then 5.0.1 again from fastboot. everything works fine now.
