How to enter flash mode

In Power off state, use Volume- & power key to enter Hboot, and directly select the fastboot interface.

for fastboot boot requirement, need dts matched by following:

INFO[435302364] [DEBUG] Board pid:379, pcbid:0x80, soc version:0 INFOx10000

P.S. Seems this fastboot interface can't use general fastboot for flashing partition, need to use another method to flash.

Installation

"The device must as S-OFF mode for installing custom kernel!"

For S-ON device, maybe recovery partition install lk2nd and boot to lk2nd can ignore the hboot limitation and can modify the system partition. (in recovery it'll always read-only.)

P.S. this device is named as Desire 820f (d820f), not d820s
