Now that I have a replacement unit on the way, a bit of an off-topic question if I may. Will I need to re-import my wallet into sparrow even if I'm using the same seed? I assume that would be the same XFP as well. I'm planning to just restore the cold card backup file I generated with the previous cold card.
You mean to pair your new device
(with SEED which equals to the old one) to Sparrow again to be able to control your stash, right? I don't think there will be a need to do this. Sparrow is descriptor based wallet, relevant descriptor on Sparrow is kept untouched, thus your new device will posses all power to communicate with Sparrow.
(Tell us If I'm wrong )
