When I try do Fix Permissions in recovery (TWRP 18.104.22.168) it gives error
Can't check permissions.
(/data/system/packages.xml not found)
(a) TWRP detected /data but it's empty.
(b) TWRP can't mount /data properly.
I already try mount /data first but still no go...
Edit: Reply from Rom developer Pixelfreak: "i have no packages.xml in my rom... the compile make no packages.xml...i work not with TWRP to much mistakes with this"
You are using a ROM with DataOnExt activated. Set the correct path in TWRP -> Settings -> DataOnExt.
