我将pin10和pin9短接的，需要强制恢复才能进行刷机，但是我通过usb识别到的不是7f21，而是一个7020 ，通过看那个表没有与之对应的，我不知道为啥短接了，识别到是错的
I short-connected pin10 and pin9, and forced recovery was required before I could refresh the machine. However, what I identified through usb was not 7f21, but a 7020. After looking at the watch, I did not know why I short-connected it, and I recognized that it was wrong
然后通过guide输入刷机指令
Then enter the brush command through guide
下面错误
