o.k, this is surprising - while I can see the information following your link, this is most likely a web-cache picture. Because if I then seek it on google-play - it doesn't show anymore.

So, if you still can download it, this would be a problem of google - that they don't update all their sites / local stores at the same time. In my area, I can't download it anymore.

But to the rest: There is no team actually developing Electra, and this has been announced in early december, and the end of live of the mobile wallet has as well be announced as taking effect on january 1.

The former Team left to XEP.

As I didn't agree that the mobile wallet holders should be left out in this way, I tried to help by looking for options (I'm not a developper, and not a holder of ECA on mobile wallets - so it's just a technical problem I was looking for a work around / to help others).

The tool I was able to adapt marginally to include / support ECA - and that as you showed - works if you have a Mnemonic in English - seems to use a different set of characters for Korean (I looked them up on the code - the words seem to be flatter than on the BIP 39 mnemonic word list.. - So - may be - the tools doesn't work with korean - or - in case there would be some diffentiation in the korean alphabet as well as with UPPER CASE / lower case letters - it would only support the other variant ("lower case")

And yes, everytime you hit a language select button on the tool, it seems to download much of the code from the original website, ignoring the information already displayed - thus deleting the entry for Electra [But if you DONT select language, it should still work, as it will recognize words in all languages in wordlist - but only in lower case (and what would be korean "lower case" - I don't know),
