Tried this tool -
http://brainwalletx.github.io/ chains tab, armory and put in the 18 4 char alphas in the paper backup text box. This generates addresses but none of them have anything in them (at least not the first 20 and the tool seems to be limited to generating the first 100).
That tool should work but it can only generate legacy addresses (
P2PKH),
if you've used the other addresses in Armory before, then your only option is to use Armory to restore that backup.
Note: When copying your root key into that tool, paste it one line at a time (
9 set of 4 characters per line).
-snip-
Is there any chance a different tool is going to come up with some addresses or is this the wrong wallet root key (I definitely have one somewhere that has something)?
There's a great chance that the tool is working as intended if the restored "
Wallet ID" is correct,
in brainwalletX's Armory tool, it should show up above as "
uid: xxxxxxxxx"
