Manual:RouterBOARD bad blocks
110
Important! As you can see in the screenshot above, RouterOS shows you writes per NAND TOTAL, not writes per
sector. This is different than the given 100'000 write guarantee per sector.
Manual:Password reset
RouterOS password can only be reset by reinstalling the router, or using the reset button (or jumper hole) in case the
hardware is RouterBOARD.
For X86 devices, only complete reinstall will clear the password, along with other configuration. For RouterBOARD
devices, several methods exist, depending on our model.
Button reset
Most RouterBOARD devices are fitted with a reset button.
Using: unplug the device power, hold the button, apply power and wait until the USER LED starts flashing. Now
release the button to clear configuration.
Note: If you wait until LED stops flashing, and only then release the button - this will instead launch Netinstall
mode, to reinstall RouterOS.
