How to upgrade routerboard to 3.38.3?
I want ot use this new functionality:
https://wiki.mikrotik.com/wiki/Manual:RouterBOARD_settings#Protected_bootloader
changed few days ago:
“reformat-hold-button-max (5s .. 600s; Default: 10m) Increase the security even further by setting the max hold time, this means that you must release the reset button within a specified time interval. If you set t he “reformat-hold-button” to 60s and “reformat-hold-button-max” to 65s, it will mean that you must hold the button 60 to 65 seconds, not less and not more, making guesses impossible. Introduced in RouterBOOT 3.38.3”
but i have routerboard 3.33 on ros 6.38.1
How to upgrade?
