Link to the old openwrt Forum is dead? Any help with this?

The first link to the forum is dead :-/

Is there any guidance how to flash the easybox 904 xDSL the easy way in 2020?

"There fore it is useful to connect to the board via serial adapter. (Of course you need the unlocked uboot, see https://forum.openwrt.org/viewtopic.php?pid=284534#p284534 how to flash)."
