To cut a long story short my friend lost a passphrase for a ledger wallet.
So following the advice of some helpful people here I asked them to use iancoleman.io to try the 24 word see combined with some possible passphrases and compare the addresses.
 However her address begins with a "b", and Iancolman.io doesn't seem to give addresses in that format.
Can anyone suggest a solution?
Thanks
