Fix blurry issue on Chuwi Hipad Pro

Hello Tanzawa,

You need to do these before using fastboot to unlock bootloader.

  1. install adb driver
  2. go to Settings > System > Developer options > OEM unlocking

There are a number of Hipad Pro users tried to unlock bootloader via fastboot command lines but cannot do it yet. Seem like their devices need official unlock tool. Not sure if this would happen to your device.
