Zyxel NSA320s restore - mtd1 needed

Hello everyone,

I am looking for a way to recreate mtd1 (populate it with stock env values). I have a dump of original envs:

/tmp # ./fw_printenv
bootargs=console=ttyS0,115200 mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) root=/dev/nfs rw init=/init
bootcmd=nand read.e 0x2000000 $(kernel_addr) 0xA00000; bootm 0x2000000
bootdelay=2
baudrate=115200
loads_echo=0
ipaddr=10.4.52.165
serverip=10.4.52.7
rootpath=/srv/ubuntu
netmask=255.255.255.0
nandEcc=1bit
kernel_addr=C80000
MODEL_ID=AF03
PRODUCT_NAME=STG-326
FEATURE_BIT=00
CONTRY_TYPE=FF
VENDOR_NAME=MitraStar Technology Corp.
run_diag=yes
ethaddr=4C:9E:FF:58:A4:10

and I have original boot (mtd0) - but I don't know how do I restore those envs back to mtd1 (I am afraid to type it by hand, to avoid bricking the device). Can you please help me and send me stock mtd1 from Zyxel NSA320s? Any help would be greatly appreciated!

newer Kirkwoods like yours cannot be bricked, as long as you have serial connection to the board's TTL pins you can reload a whole uboot over serial or fix the envs by using the uboot's own tools
