I do not have the balance two, so I do not know if this applies –
Double check before trying!
If you can’t reset from incontrol, I found with a balance without LCD, holding the reset button briefly reset the admin password without doing the full factory reset. Holding it longer (10 seconds – I’m not sure the exact duration) resets it fully I believe. Double check before doing so.
