Anyhow, I managed to do it. I booted new LEDE iniramfs kernel.. Then did ubiformat, ubiattach, ubimkvol on mtd6 ONLY, I labeled it "rootfs" mounted it, transfered rootfs.tar.gz and extracted.. then booted initramfs kernel of old openwrt and formatted mtd5 ONLY and only block device like mtd erase kernel then I mounted kernel mtdblock5 , transfered -lzma.elf kernel and rebooted. viola, boots with lot of nand errors, but I see it working good.
so .. if I could help someone.. here it is.! I hope there can be some nand error checking in sysupgrade! sysupgrade says it flashed success but bootloader says there is no kernel. Other device - no problem.
