I put the routeros-mipsbe-6.38.1.npk file on the root of my routerboard and rebooted it. Now it is bricked- in a continuous reboot loop.
I've tried holding the reset button for 1sec, 5sec, 10sec on boot. I think my only remaining option is netinstall, but I don't have a Windows machine anywhere. OSX only.
I do have another Mikrotik board. Can I do a netinstall from that? Do I have any other options aside from scrounging up a Windows box to do netinstall?
