So I'm trying to restore a very old wallet from the darkcoin days. It's in the format darkcoin_wallet_backup_2014-xx-xx. Instructions for restoring this type of file point to using the android Dash wallet. But it doesn't work sadly. The restore wallet screen comes up and asks for a pin. It also says to put the file into /Downloads and there is a dropdown requester for specifying the file to restore, however it does not work to select a file. No dropdown activates. I've tried this on an Android 7 and Android 6.0.1 devices with the same behavior. Is the pin requested for the current wallet or for the wallet being restored? I'm very, very interested in getting this to work obviously!
