1、下载所有文件

2、跳线连接GND-FEL，插电脑，装驱动 zadig-2.8.exe

https://linux-sunxi.org/FEL/USBBoot#Using_sunxi-fel_on_Windows

--来自百度网盘超级会员V5的分享

3、打开下载文件夹，输入cmd 回车

4、执行以下命令，等有空再写批处理吧……

sunxi-fel spl sunxi-spl.bin 
sunxi-fel -p write 0x4a000000 u-boot-dtb-temporary.bin 
sunxi-fel -p write 0x42000000 sunxi-spl-with-ecc-toshiba.bin
sunxi-fel -p write 0x43000000 sunxi-spl-with-ecc-hynix.bin 
sunxi-fel -p write 0x43400000 u-boot-dtb-perm.img 
sunxi-fel -p write 0x44300000 flash_bootloader_erase_nand.scr 
sunxi-fel -p write 0x44400000 bootimage_swupdate.itb 
sunxi-fel exe 0x4a000000

执行完毕，等待一段时间后chip会自动关闭
然后再去掉跳线，重新插上usb
长按chip上的小按键亮灯开机，或者是pocketchip按到开机，等一段时间，设备管理器里会出现串口，如果没有就装一下串口驱动
zadig-2.8.exe

5、装RNDIS驱动

选RNDIS那个文件夹
然后在浏览器里打开http://chip.local/或者http://10.10.10.10/
选ntc-chip_2022.02.25.swu等刷完

感谢网友@777提供的刷机图
