RB2011L-IN keep rebooting

Sir/Madam,

I have RB2011L-IN routerboard with Level 4 license. It was running in routeros-6.0rc11.
I tried to upgrade in routeros-6.1 by uploading the routeros-mipsbe-6.1.npk into the Mikrotik File but I accidentally uploading also the user-manager-6.1-mipsbe.npk. When rebooted, it won’t boot up again and keep rebooting. The LED indicators #6-10 keep flashing around every 10 seconds.

Any advice to fix this problem?

Thanks,
Leon

I suspect that it is time to netinstall the device.
