Alright, its figured out.
Downgrading and upgrading the code via the console, corrupts the configuration, there by allowing to login to the switch with the default username and password.

Should be:
From Technical Document:

To reset an OmniStack to factory defaults - you'll need to connect via a console serial cable, then:
hit any key when prompted by boot process immediately after power-up to get to boot/diagnostic menu
enter 'c'<return> (don't enter the quote marks!)
enter <return> until line displays: "Boot Flags :0xb" then enter '0x1000'<return> at end of line
enter <return> until back at the "[Boot]:" prompt
enter '@'<return> to boot
system is now reset to factory defaults
Login as 'admin', initial password 'switch'
enter 'pw admin', to set a more suitable password


Other:
Stop Auto boot
With L list all files in NVRAM
Delete mpm.cfg and mpm.cnf with the command R

I think it will reset the whole switch, so config is gone as well. If you have another user (smmp?) use this for login and reset the password for admin
