Hello all,

I cleaned my warehouse and between other ancient hardware, i found a RB333..
I connected it, power, ethernet and serial, as an idiot I managed to format nand, so i re-installed routeros and wrote a mail to MT support for a new key.
I also forgot it open for a few days, so the licence expired, but the strange is that it boots, starts services, stop services, reboots but no sign at the terminal.
As if serial port is not working.. For sure it worked. Sometimes, when i attach the power, a character is displayed on the terminal. Just this..
Of course i pressed the reset button while booting, I tried almost everything..
I need the serial to reformat nand and install new software..

Any suggestions ?
I tried misc power supplies from 12V to 24V. The serial cable is working for sure, i tried it with some RB133s i have.

The only way is to ask support@mikrotik.com for help.

I just did

Use NetInstall to reinstall RouterOS they will give you another I thing 72h or 48h hours working time to enter licence. They counting time only when working.
For licence make supout.rif and send to support they will generate licence for that board without time limit.
