:) Thank you guys
I've removed the power completely and after that, it worked.
Pretty strange anyway... Never get into this until now.
Once again thank you all!
thanks mate!
No, I don't have any USB device connected (never did).
And I'm installing the same way I've done it many, many times.
What's different now?
I'm upgrading from 384.4_2 and it's happen something that never did - after everything is done I'm still on 384.4_2.
I've rebooted the router and tried again - the same result.
What could be this?
