How to enter flash mode
In Power off state, use Volume- & power key to enter Hboot, and directly select the fastboot interface. P.S. Seems this fastboot interface can't use general fastboot for flashing partition, need to use another method to flash.
"The device must as S-OFF mode for installing custom kernel!"
P.S. this device is named as Desire 820u (d820u), not d820s P.S. the system image is same as Desire 820 Single SIM, but device tree image is different.
