Ax3600 link not working

Hi, I am trying to install OpenWRT in my Xiaomi AX3600 according to this link
https://openwrt.org/toh/xiaomi/ax3600#tab__patch_bdata_method
However, when I try to download from this link (I guess it is a file containing the create_exploit.js file)

It seems to be no longer available. Can anyone please re-upload or to send me it? Thank you
