This might help. It's for the Cudy WR3000, but it looks like an identical issue.

Support for Cudy WR3000

further OEM firmware investigation got me this line blocking dropbear /etc/init.d/dropbear [ -f /etc/rom_release -a x"$(bdinfo factory)" != x1 ] && return removing it was faster than puzzling this code then to make it survive sysupgrade echo "/etc/init.d/dropbear" >> /etc/sysupgrade.conf I've done it by booting initramfs-kernel in safemode and mount root but there might be other solution like sysupgrade edit .
