Note that the number at the end indicates the size to write in hex.

Then we proceed to flashing OpenWrt itself (which we called nsa325.bin for less typing): Setenv bootcmd 'run setenv bootargs ubi part ubi ubi read 0x800000 kernel bootm 0x800000'ДЄfter the device reboots into the OpenWrt u-boot we adjust the device's MAC address (adjust the values, see the sticker under the NAS case): Now we set the correct environment variables:

If your USB stick isn't recognized/found by u-boot, try putting an active (powered) USB hub between the NAS and the flash drive.ДЄfter plugging in the USB stick (use the rear USB ports), into the NAS, with the correct files and booting into u-boot, first step is to install OpenWrt's u-boot: Make sure to write down your device's MAC address as we need to set it later! Otherwise it would get lost! Please note that to write to NAND you have to erase the NAND first, which means all data on the NAND will be deleted! Meaning stock firmware, bootloader, settings and everything will be gone! So make sure you got the proper files ready before you start as it's vital that you flash the new bootloader before you restart your device as it would otherwise get soft-bricked. Use the latest u-boot.kwb from the 18.x.x release instead. Rename the -factory.bin to something simple like nsa325.bin.ДЄttention: the u-boot.kwb from 19.x.x release is bugged and won't allow access to any mass storage.

We will then copy the required files to the USB stick and command the device through a terminal (using serial) to load and flash our files to NAND.Д¬opy the u-boot.kwb and -factory.bin files to a FAT32 formatted USB stick with msdos partition table (single partition). Zyxel products are typically used by small businesses as firewalls and VPN gateways. So in addition to using a fixed password, it appears the password was also sent in the clear over FTP. We require a USB stick (FAT32 formatted, single partition) and a 3.3V USB to serial adapter. According to Zyxel, the password was used 'to deliver automatic firmware updates to connected access points through FTP' 2.
