How to enter flash mode

  • Apply for bootloader unlocking file at ZUI official website (Chinese): https://www.zui.com/iunlock

  • After unlocking, you get a menu to select boot mode every time the phone powers on. Choose bootloader to enter fastboot mode.

Installation

Notes

Partitions

The persist partition stores device-specific information like WLAN & Bluetooth MAC. You'd better leave it as is. I don't know how to recover it.

LED / Torch / Screen brightness / vibrator

Write brightness or boolean value to specific sysfs files:

  • Front panel LED light: /sys/class/leds/{red,green,blue}/{brightness,blink}
  • Torch light: /sys/class/leds/led:torch_{0,1}/brightness (torch_0 is cold light, torch_1 is warm light)
  • Screen brightness: /sys/class/leds/lcd-backlight/brightness
  • Vibrator: echo $TIME_MS > /sys/class/timed_output/vibrator/enable

For brightness range, check the max_brightness file.

WiFi

Loading wlan driver on boot (default setting) will significantly increase booting time (half a min -> 3 minutes to GUI). I don't know why.
