  1) Create New
  2) Restore Existing
  Please choose: 2
  Please paste the path to your XUD backup to restore your channel balance, your keys and other historical data: ./sda
  Checking files... Path not available. Do you wish to continue WITHOUT restoring channel balance, keys and historical data? [Y/n]

Enter your 24 word mnemonic separated by spaces:

Good idea! So one super small addon for Roman's case above @rsercano : Do you wish to continue WITHOUT restoring channel balance, keys and historical data? [Y/n] -> Do you wish to continue WITHOUT restoring channel balance, keys and historical data? [y/N]
