Regardless of your password or wallet file being corrupted... You should still be able to recover using the seed. The fact that your seed is coming up with an empty wallet, leads us to the only logical conclusion. Which is that, unfortunately, some how you have ended up using a different wallet than the one you copied the seed down for. Undecided Possibly a wallet file that you had already  generated before creating the one that you have the seed for... But then by accident you started using the first wallet which you didn't have the seed for.

How many files are in the "wallets" directory if you select "file -> open"?

If you have multiple... Do any of the other wallet files contain the same addresses as the wallet restored with your seed?

I should but i can't. I'm sure about the sed words, sure about the password. I make three copies of it. I have only 3 wallets, i check the password of each and the seed , everything is in the right place. I try old versions of electrum. I try in a second pc.
I don't know what to do seriously. I am sure the wallet is corrupted, because normally i can restore an older version. On this particular wallet, i can't.
My only chance, it's maybe to restore the old password but i don't know if it's possible and how to do it.

I only use this wallet when i change the version. I am sure that when i install first the 3.4 version and 24 hours later the 3.5 version with changing the password, it makes something about the wallet and the password...

I have the seed before the upgrade and the new one.
I'm a bit confused about this... So, you have 2 seeds? Why do you have 2 seeds? Huh

You should have had one before the upgrade and you should be using the same one after the upgrade.

Was your old seed an old MultiBit HD seed that you imported to Electrum? If so, you would have used the BIP39 seed option... When you do this, Electrum doesn't check the seed for correctness, so you need to be extra careful when typing it in. Also, just checking that when you restored from seed after the upgrade that you changed the derivation path from the default of m/44'/0'/0' to m/0' right?

Or when you migrated from MultiBit did you create a new Electrum seed and moved the coins from old addresses to new addresses?

No one seed. Only one.
No , i don't imported multibit seed on electrum. I transfer my bitcoins from multibit wallet to electrum wallet. It was 1 year ago.
Since, i did not have any problem. All begins with first installation of electrum 3.04 and next electrum 3.05 and when i change my password.

i really think my wallet.dat is corrupted.

Oh, so you actually changed your password during the upgrade? Then it sounds like you have mis-typed your password when you were entering the new one... maybe you had capslock on my mistake? or if you used the "shift" key to type uppercase/symbols then you may have inadvertently typed some extra uppercase or accidental lowercase letters or typed a letter instead of a "symbol" etc...

In this case, btcrecover might be very helpful... it can automatically try various combinations of common "typing errors"... especially if you are fairly confident you know what the password SHOULD be.

As for the seed words... I'm wondering if during the upgrade, you got the seed words for a new unused default wallet by mistake? and not the seed words for your actual wallet. Where/how did you double check the seed words? and did you not have an earlier backup of the seed words written down somewhere?

It is also possible that you've simply spelled one of the words wrong and it just happens to make a valid seed. Some of the words are very similar and it is easy to mix them up (kid, kind, kit, kite etc)

If you know of one of the first few btc addresses from the wallet, btcrecover also has a "seed recovery" option that might be able to identify errors in your seed if it is simply one or two wrong words (this won't work if it is just completely the wrong seed however)

Not during the upgrade, after the upgrade. It was a security problem. So i change it.
I'm sure 100 % of my password. VERY VERY SURE. I have the seed before the upgrade and the new one.
I check everything 10 times, believe me. I'm not kidding with this kind of stuff.

I had a similar problem with Multibit. And that's why i transfer all on Electrum. Now, i'm stuck with 2.5 btc on the wind.
I don't know what to do. I try with btcrecover but i can't make it works... I'm desperate..
Thanks electrum

1 / Last time was the 8 th january.
2 / I have the seed words. When i put them, i have my wallet back, but no money on it, no transactions, no history, nothing...
3 / Standard Wallet
4 / 2.8 to 3.04 first and 24 hours later 3.05 all from the Electrum official Website. I did all the verification, i was very suspicious about the new version...
If you look in the wallets folder (http://docs.electrum.org/en/latest/faq.html#where-is-my-wallet-file-located), are there other wallet files there? It's possible that you were not using the "default_wallet" with the earlier version of Electrum, and when you updated to the newer version, on first start, it defaulted back to "default_wallet", hence why your password is not working.

As for the seed restoring an empty wallet, have you ever used your seed words to restore your wallet before? It would seem you have a "valid" seed, but not the seed for your wallet Undecided I've seen several users over the last few months who have written down a valid seed but have some how ended up using a different wallet... So, when they try and restore from seed, they get an empty wallet.

Good point. I try it , but it's not default wallet or other one.
When i put the new version, i changed my password. I wrote it. And i check again the seed words and i wrote it.
I'm sure 100 % of my seed words and my password. I tried everything except using btcrecover... This is a shame.

Who have any solutions, it will be great and i will a reward for getting my wallet back.

There are no viruses in Electrum that remove the installed applications of antivirus. I used the official update of Electrum for but I have no problem. I think your downloaded software is infected or you download unknown wallet. So download the official wallet and used Electrum , do not worry.

I used the same official electrum, i check it. I have a big problem with it.

I gat the new version of Electrum... Now impossible to open my wallet with the right password...
Then the password you are typing in is incorrect. When was the last time you used the password you are trying to open the wallet? Was it months ago? or was it yesterday?


Quote
And when i try to recover it wth the seed words, it doesn't works...
How exactly are the seed words "doesn't works"? Is it giving an error? Is the "next" button not available... is it just showing a 0 balance? do you see any transaction history?

What sort of wallet was it? Standard? MultiSig? 2FA?

What wallet version did you upgrade from? What version have you just installed?

Can you confirm you downloaded the file from: https://electrum.org/#download and did you check the digital signature?

Something wrong with Electrum and this story...Be very careful and thanks for any help.

I did verifying signature's process with GPG Kleopatra. electrum 3.0.5 verified but says the data could not be verified. Is there any problem with Electrum 3.0.5?
No... it is just the way that GPG works... you can import keys, but not TRUST them... until you explicitiy trust the key you will see something like:



NOTE: THIS IS A GOOD SIGNATURE! The signature checks out, and the file is signed with the signature... YOU just haven't trusted it yet.


If you "trust" ThomasV... then you can sign the key, saying that you vouch for Thomas and he is legit and all things signed with his key are legit... then you will see something like this:




The important thing is that you DON'T see a red warning like this:


If you see "Invalid Signature" then that is BAD!

Very strange Electrum 3.04 seems a phising link for me...They say to update but i can't read nothing on electrum official website.

This warning is written at the top of the electrum website home page. I don't know how you missed it.

https://electrum.org/#home


I don't see it either. could you give us a screenshot?
Maybe electrum.org is hacked.

For the record, the v3.0.5 downloads are here: https://download.electrum.org/3.0.5/
Huh? It has been showing 3.0.5 for me for a long time. Try clearing your cache.


Version 3.0.5 got released about 13 hours ago, as a follow up to 3.0.4 (which mostly shut down the vulnerability) [1].
No way you got 3.0.5 for a long time now. You might verify the signature of your current version to exclude the possibility of a malicious application.
