Sent from my HTC Butterfly s using XDA Premium 4 mobile app
I just read a reply from koniiiik, this one in here:

As he says: "The problem in this case is that many HTC devices, including the Butterfly s, implement some kind of write protection on the /system partition. Its effects are that even when you remount /system as read-write and make changes there, they don't actually hit the partition and appear to be stored in RAM.
.....
In order to change the contents of the /system partition persistently, you can't make changes from within a full Android environment, you have to make them in your recovery."
So, this is my problem. In my uderstanding, the only way I can make my permissions file and hosts file (for adaway) to work, is by flashing in recovery.
Ok, I did a flasheable zip to fix the permissions to write to SD and it worked perfect. How can I host it if another member need it?
