Bootloader upgrade

Manual:Bootloader upgrade
This page shows how to upgrade the Bootloader firmware of a RouterBOARD device.
First, check your RouterOS version - does it have the routerboard package installed?
[admin@MikroTik] > system package print
Flags: X - disabled
# NAME VERSION SCHEDULED
0 system 4.0
1 routing 4.0
2 hotspot 4.0
3 advanced-tools 4.0
4 mpls 4.0
5 security 4.0
6 X ipv6 4.0
7 ppp 4.0
8 dhcp 4.0
9 routeros-mipsbe 4.0
10 routerboard 4.0
11 wireless 4.0

Then, check your RouterBOARD Bootloader version:
[admin@MikroTik] > system routerboard print
routerboard: yes
model: "750"
serial-number: "1FC201DD513B"
current-firmware: "2.18"
upgrade-firmware: "2.20"
[admin@MikroTik] >
In this case you see, that there is a newer version of the Bootloader firmware available already inside your current
RouterOS version. Note! New Bootloader versions come with the routerboard.npk package when you install and
upgrade your router, this is why always make sure you have not forgotten to install this package.
Do the upgrade command now:
[admin@MikroTik] > system routerboard upgrade
Routerboot will be upgraded.
Manual:Bootloader upgrade 2
Second method
If for some reason routerboard.npk package is not, and can not be installed for your RouterOS version, you can
upload the Bootloader file directly to the Files folder in RouterOS, and do the command then. Bootloader FWF files
are available on the RouterBOARD homepage [1].
Third method
If there is no IP connectivity with your RouterBOARD, you can also use the Serial Console XMODEM transfer to
send the FWF file to the router, while connected via Serial Console. From the Bootloader menu it s possible to
upgrade the firmware with this method. This method is the last resort, and should be used only if the first two
methods are not available.
