Return error
Error: Please enter the wallet passphrase with walletpassphrase first. (code -13)
Glad to see that your problem was solved, although I would never have suggested that you need to unlock your wallet before importing your private key, because that seemed to obvious...
The rather more interesting question is "How did you get your private key" from Ellipal(I'm actually only asking out of technical curiosity, because I have neither coins on Ellipal nor on a Electra-mobile App - but may be a solution could be of interest to people who have their coins stuck on Mobile Electra wallets, unless / until they come (eventually) online once again....)
I know that Coinomi offers a link to a tool that allows to extract private keys, if you only know the Mnemonic... Tried this with the Mnemonic from my (empty) Android Electra wallet. Now, the tools supports many coins, but not explicitly Electra... So I looked if from Adress-Format / Private Key Format another coin would come very close... Indeed, the result for EINSTEINIUM looked like an Electra address (both address format AND Private-Key-Format). But - unfortunately - I couldn't find my ECA-Address from the mobile wallet on that list... - although I could import that private key in to the Electra-wallet, and it was accepted as belonging to the same Address as on the list, so the format (including formula for private-Key/Address generation) seems to be identic between ECA and Einsteinium...
So, the question, how to extract a private key from Ellipal - just for fun, I donwloaded the Ellipal app as well, insertet the same Mnemonic, selected ECA as Coin, and received an address (but, unfortunaltely, again not the same as on my Mobile-Electra wallet). And, of course, I couldn't find any information in the Ellipal App OR on the Ellipal webpage how to get the private-key for that address...
So, the question, how did you get your correct Electra-private key out of Ellipal might really be of interest to several Electra-Holders with coins on their mobile wallet...
Hello
I write in this post (I think) how extract Private Key from Ellipal.
I have this problem I solve with Ellipal team on email (max 20 hours to respond on email).
Well
Open Ellipal app on the phone.
Go to my account.
Add account.
Use Mnemonic words.
Rename "Old account" with "Old account new".
In "Old account" color of screen was blue. In new account color of screen is orange.
Go to Profile.
Go to Manage account.
Go to new wallet.
And there you have Private Key, Keystore, Key.
I hope to help.
If it is necesary I write here my corespondence with Ellipal team.
Enjoy
