USB to TTL converter delivered today, so I have succefully debricked Belkin. I have find out, that I can´t flash openwrt or stock firmware (tested flashing via U-Boot), so I am still using latest LEDE.
If I try to flash last openwrt i get this (bricked Belkin 4 days ago):

I think, that I am stucked on last LEDE for now and I can only hope, that this problem will be solved with flashing newer LEDE in future.
