Xiaomi AX3600 GD9FS2G8F2A NAND flash dump file?

Briked my Xiaomi AX3600, sadly to me standard TFTP recovery do not work, last hope is to flash NAND flash with programer.
Maybe somebody have GD9FS2G8F2A NAND dump and willing to share?

Found the link to https://www.right.com.cn/forum/thread-7659973-1-1.html, but it is imposible to register for people outside china.

Thank you in advance!
