+This router supports dual boot, and has two partitions for the firmware, `ubi` and `ubi2`
+
+To check the current active partition you can use the following command:
+```sh
+cat /proc/cmdline
+```
+The result will be something like the following:
+```
+console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 rootubi=ubi
+```
+If `rootubi=ubi` it means that the active partition is `mtd6`
+
+If `rootubi=ubi2` it means that the active partition is `mtd7`
+
+{% include alert.html content="When you flash a new firmware via the web interface the router will automatically write the new firmware in the inactive partition, hence if the firmware upgrade is successfull it will automatically swap the boot partition at next reboot.

+## Firmware Version V5.70(ACDZ.0)C0 no-brand
 
-- [source GPL package V5.70(ACDZ.0)C0](https://github.com/ErnyTech/zyxel-ex5601t0)
+Here is a no-brand firmware compiled starting from Zyxel provided OpenSource package under GPL license (link at the bottom of this page) plus the following modifications that you can track on the following repo:
+https://github.com/pameruoso/zyxel-ex5601t0
 
+1. Added start-up script to reset and enable root access via ssh.
+The script reads the device serial number and resets the root password with that. Do not try to reset the root password because that will last until next reboot.
+2. the `/bin` path contains `sfp_wan.sh_wind` and `check_sfp_link.sh_wind` scripts which are very similar to the standard `sfp_wan.sh` and `check_sfp_link.sh` scripts. If everything works with the original ones do not swap them. If you want to allow 2.5gbit HSGMII with AFM0003 sfp stick you need to swap and enable the `_wind` scripts.
+3. Additional packages installed: `mtr`, `htop`, `openvpn`, `wireguard`.

-The firmware contains the following modifications too:
 
-1. Added start-up script to reset and enable root access via ssh with password "passwd". Do not try to reset the root password because that will last until next reboot.
-2. the /bin path contains sfp_wan.sh_wind and check_sfp_link.sh_wind scripts which are very similar to the standard sfp_wan.sh and check_sfp_link.sh scripts.
