Set vibration strength on boot

Note: you have to use custom kernel: http://forum.xda-developers.com/huaw...ernel-t3219576

Default voltage is 126. Higher voltage might damage your vibrator.
Value 60 is less than default and for me it gets me more haptic feedback with lower acoustic levels.

1. connect to watch with adb
   
   
   

   Code:

   
   

   ---

   adb shell

   ---

   
   


2. switch to user root
   
   
   

   Code:

   
   

   ---

   su

   ---

   
   


3. first you need to remount system partition to read/write
   
   
   

   Code:

   
   

   ---

   mount -o remount,rw /system

   ---

   
   


4. then you will create script that will set vibrator to certain value on boot
   
   
   

   Code:

   
   

   ---

   echo '#!/system/bin/sh\necho 60 > /sys/module/drv2605/parameters/current_voltage' > /system/etc/init.d/vibrator.sh

   ---

   
   


5. now you need to make the script runnable (permissions to run)
   
   
   

   Code:

   
   

   ---

   chmod 777 /system/etc/init.d/vibrator.sh

   ---

   
   


6. remount back to readonly
   
   
   

   Code:

   
   

   ---

   mount -o remount,ro /system

   ---

   
   


7. now reboot the watch

After reboot the first attempt to vibrate will be still on default vibration strength, next one (and all after that) will be with voltage you have set.
