Hey there,

I just have updatet to Nougat. I made the mistake to copy my data backup to the partition before the first boot. It seems to have provocated some permission issue.

For instance i couldnt make screenshots because the app couldnt write to data/pictures.
I also have issues with updating/installing apps, resulting in error 492. It isn't possible either to backup any app with TitaniumBU (no space error).

I suspect that every folder created prior to the boot has an incorrect permission set. Probably read only. How can i fix it?

Thanks in advance

(i am rooted)
