How to write Android firmware

Dear community

I offer some ways to swipe Android firmware.
We currently offer firmware in two formats:

android9-*-rkupdate.img
android9-*-gpt.img

rkupdate

Rockchip official firmware format. We can use official tools to burn.
linux tool

RKTools/linux/Linux_Upgrade_Tool_*.zip

windows tool

RKTools/windows/AndroidTool

Connect to your storage medium(emmc/sd/…).
Press the maskrom button and plug in the power supply.

In Linux, for example

  1. Display device list
$ upgrade_tool ld

List of rockusb connected(1)
DevNo=1	Vid=0x2207,Pid=0x330c,LocationID=10402	Mode=Maskrom

  1. Burn the firmware
$ upgrade_tool uf android9-*-rkupdate.img

gpt

Radxa custom format.

SDCard
Emmc

If you don’t want to use tools

#/dev/sdc is my sdcard
dd if=android9-*-gpt.img of=/dev/sdc bs=4M status=progress

I would be inclined to NOT use the word “burn” in this context. That word is a hangover from the days of WRITE-ONCE media. Things like non-erasable PROM, CD/DVD-R, etc.

Instead say “How to write Android firmware”.

OK, Thank you. I will modify it.
