Importing bitcoinj mnemonic into electrum or deriving private keys from mnemonic
Just restore as normal using electrum and on the screen where you have to enter the derivation path you set it to m/0' and choose legacy as the script type. Then create another wallet via file &gt; new/restore for the p2wpkh addresses. This time choose native segwit as the wallet type and enter m/1' as the derivation path.
