# S-ON-on helpo

## HTC aranĝaĵoj

AdAway does not work when you are using a device with so called S-ON. This 'feature' exists on many HTC devices and prevents AdAway from writing the hosts file.

## S-ON/S-OFF?

S-OFF means that the NAND portion of the device is unlocked and can be written to. The default setting for HTC devices is S-ON, which means that neither can you access certain areas of the system nor can you guarantee a permanent root. Furthermore, signature check for firmware images is also ensured by the S-ON flag.

## Do I have S-ON or S-OFF?

Boot into the Boot Menu on your device by holding down volume down button while pressing power and the text on top will show the flag status as either S-OFF or S-ON. A full root generally means S-OFF.

## Workaround

Prerequisite: You have to install a working Android SDK with ADB shell on your PC.

1. Boot into the Boot Menu on your device by holding down volume down button while pressing power.
2. Use volume down to select recovery then power to boot it.
3. In clockwork recovery go to "partitions menu".
4. Select mount /system, mount /sdcard and mount /data.
5. Plug in your USB cord and open a command line on your pc.
6. Enter adb shell and type `ln -s /data/hosts /system/etc/hosts` (This creates a symbolic link, which allows AdAway to edit the hosts file stored in `/data` while allowing the OS to use the file as if it were stored in `/system`.)
7. Reboot your device and set Target hosts file to /data/hosts in AdAway's preferences.
8. AdAway should work now.
