It's somehow stuck on this firmware.
I tried upgrading to 1.0.36, the form accepts the file and restarts fine but it restarts into this same firmware version again.
Tried downgrading to 1.0.32,1.0.31,1.0.29 every single time it accepts and validates the file but reboots into the old one again.
Got this and newer firmwares from Netlink
