RB2011-iL-RM after botnet attack

Hi!

I have problem with RM2011iL-RM after botnet attack, I am unable to load newer firmware. Device currently runs on 6.40.3 and it ignoresany attempts to load firmware. When I load npk file to files section, its not upgradeing after system reboot command. Netinstall doesntwork either, I have tried various systems and machines with no luck. Probably its still infected because after connecting it to the internet modem in my house, modem stopped working(!) I tried autoupgrade via internet but after downloading 98% of files, connection breaks, Mikrotik is restarting. How can I format partition if there is no serial onboard? Please help me.

Regards, Kamil.

Netinstall is the solution. There are some topic on netinstall and how to make it work on this forum, have a look.

Okay, disabling APIPA solved problem with connection. Thank You.
