Zyxel z2 ( NBG6817 ) env-vars and u-boot

hey there, i just got an NBG6817 that was flashed with a custom built firmware and also a recent u-boot. it does allow switching firmwares by holding down the WPS button but it messed up all the u-boot env variables

So can I generously get a copy of the " fw_printenv " command of a fellow owner ? :cold_sweat:

and a copy of the bootloader from mtdblocks ( it would be mtd8 : APPSBL for u-boot and mtd9:APPSBLENV for the env. vars on OpenWrt ) or if someone can just send me the whole mtdblocks saved as an archive and i'll just figure it out !

thanks !

is there anywhere else I can ask to get a dump ?
