RB433AH not booting

Dear All,

Please help me find a solution! I’ve configured 433AH, and it worked well. After that, I’ve shut it down and then inserted an SD card.
Next time, it did not boot up. I’ve put a consol on it, and it says:
/etc/rc.d/rc.start : 5: /etc/rc.d/rc.sysinit: not found
System halted.

It sounds very bad to me…

Any idea what to do now?

Thanks!

use netinstall

I have succesfully “netinstalled” the OS. It recognized the key, but now it says level 5, baut it was level 4.
I don’t know if it has a valid key or not.
It prints the following:
software-id: “4KXK-LTT”
upgradable-to: v4.x
nlevel: 5
features:
And there is no expires in when I checking through winbox.

What to do? I’m afraid it’ll stop working after 24 hours. Altough it didn’t tell me.

Thanks.

if it says you have a L4 key, it will work and will never expire.

if it says you have a L4 key now, you had it before as well. Keys are complicated things, your router couldn’t get a L4 key out of nowhere.
