Hardware MikroTik hardware general

Hi,

I was upgrading my RB133 router with routeros-mipsle-6.0. The routerboard now wont start and keeps giving me the following error.

Any assistance will be appreciated.

Hi, you have old routerboot. Before upgrade you must have routerboot 2.18. Now reinstal router with netinstall http://wiki.mikrotik.com/wiki/Manual:Netinstall
then upgrade routerboot to 2.18 and install 6.1 http://download2.mikrotik.com/routeros/6.1/routeros-mipsle-6.1.npk

See comment on download page:
Before upgrading RouterBOARD 1xx or 5xx series devices (MIPS-LE) to version >=5.17, please upgrade your RouterBOOT firmware by uploading one of the following files to your corresponding device, and issuing command “/system routerboard upgrade”. Download for: [RB1xx]; [RB5xx]

I just got a few RB133c3s that I am trying to reset to defaults.

  • They boot fine, but I don’t know the password to log in.
  • I can’t figure out how to get the reset button/jumper to reset the ROS configuration.
  • When using netinstall/bootp, they give a one-line “kernel panic” message.

As a last resort, I want to try upgrading the boot loader via xmodem–but although the available documentation says to download the routerboot image from routerboard.com, I can’t find a link to it anywhere. Can someone please send me a current link to download routerboot 2.18 for mipsle? Or tell me exactly how to use the button/jumper to reset the ROS configuration?
