I was only testing in worst case scenario.
If I loose my hardware and the only thing I have is a paper wallet.
Can I restore my wallet in another wallet software using the root key?
Then I cant send my funds to a hardware wallet.
Or maybe using a Linux LiveDVD on a machine disconnect from the internet. Putting bitcoin core client in usb stick and run it in that machine.
And generate a new wallet in bitcoin core client with my root key from the paper wallet.
I don't know if the bitcoin core client can do this not connect to the blockchain.
My goal is the restore a wallet in a safe way. The ideal would be restore the wallet in offline machine but without Armory.
Answer is the same, you cannot do this with the current Armory wallet format. You'll have to wait for the next version that comes with an update to the wallet format.
