my electrum wallet of 2016

[Centurio]

Hi all,

I have an issue with my electrum wallet from 2016. I did some days mining with my AMD APU for nicehash. As I did not use a passwordmanager this time, and wanted to have a good password.... oh, it does not matter anyway now.

I got my keystore file. I think it is the same as the wallet.dat.  But not sure here. The interestsing part seems to be this one here. But it is missing the private key.

"keystore": {
        "type": "bip32",
        "xprv": null,
        "xpub": "xpub661Myxpubkey111positions"

    },

There is more in the file. But mostly addresses I created to restore the wallet... There are some transactions from nicehash too.

So if there is no private key, no seed and no password. It is not possible to restore any BTC right?

I have checked the example hashes of the electrum wallets versions on hascat wiki. But I did not find anything. With John2electrum I only got the message: "This wallet is not encrypted". Nice, but how does it helps me. I remember parts of my password but that's all.

I still have a dd copy of my harddrive. But it's 4 years past since the wallet was created and it's only 120GB drive.

Any advice is welcome.
