How to make /etc/hosts writeable?
Posted: 03 Oct 2020 10:51
I am trying to dynamically replace /etc/hosts with my custom hosts file.
(AdAway is working perfectly on my phone but I need to modify my hosts dynamically using Automagic, which has Root functions enabled)
Using Execute Root Command, these are what I have tried and the result:
stderr: mv: bad '/etc/hosts': Read-only file system
stderr: mount: '/system' not in /proc/mounts
stdout:
Anyone has any idea how to replace /etc/hosts?
