Unlocking the bootloader
See Unlocking Bootloaders/Lenovo ZUI
How to enter flash mode
- 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.
