Thank you HCP. Yes, the receiving BTC address starts with a 3 and it's a 2FA wallet, script type p2sh.
Would you be able to help me to recover that? I am new and very interested in feel positive about the this new asset class for the long run. I don't have much but I can pay you from the recover coin. Thank you.
Try this:
1. In Electrum, make a new wallet by choosing: "Wallet with two-factor authentication" -> "I already have a seed" -> Paste your 2FA wallet seed -> Next and select "Disable". (Do not enter a password)
2. Now close Electrum, find the wallet file you just created (check %appdata%/Electrum/wallets) and open it with a text editor.
3. You will find 3 xpub and 2 xprv addresses at the bottom of the file. Save them.
4. Open Electrum-LTC[1] and create a multi-sig wallet with a 2-of-3 scheme with the first xprv address and the other two xpub addresses.
5. Then, make a second wallet for the second signer with the second xprv and the other two xpub addresses.
Edit: If this doesn't work, follow this:
