  • How to change clock frequency in Android?

  Set Governor:
  
  adb shell echo "userspace" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  
  Set Frequency in KHz:
  
  adb shell su -c "echo "702000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"
  //min frequency
  adb shell su -c "echo "384000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq"  
  //MAX frequency
  adb shell su -c "echo "384000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" 
  
  Get current CPU Frequency:
  
  adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
  
  Show availables governors:
  
  adb shell su -c "cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors"
  
  Disable service that overwrite cpu online file:
  
  adb shell su -c "stop mpdecision" 
  
  It's necessary to do this before enabling or disabling core. mp decision is restarted if the system is restarted.
  
  Disable core:
  
  adb shell su -c "echo "0" > /sys/devices/system/cpu/cpu3/online"
  
  If that doesn't work:
  
  & chmod 444 /sys/devices/system/cpu/cpu1/online
