Some problems with Electrum wallet

[Ry4eek]

The wallet was created on a laptop with win7, later I successfully transferred everything to a new laptop with win10. Wallet is ok work. I have already recreated a lot of wallets by my seed. All without success. As I wrote above: I managed to check my addresses, all bitcoins are in place. But when I restore my wallet there is no history and other addresses. I'm at a dead end.

Sorry, just to clarify, because it isn't 100% clear to me from previous posts and replies...

When you are restoring from seed, does the new "empty" wallet, have the same type of addresses as your "old" wallet did? That is to say... old wallet had addresses that start with "1"... new wallet also has addresses that start with "1"?

Or are they completely different? Old wallet = addresses start with "1", new wallet = addresses start with "bc1"? etc...

You should post the bitcoin address here that you got from your friend as you posted here so that we know which format of bitcoin address you have if it's segwit or a legacy wallet.
Or possibly that your backup seed has incorrect order or one of the words in your seed is wrong spelling.

Let me know if how many words in your backup seed?

[Ry4eek]

Sure.

This is one of the last addresses that could be found:

1PHVbLfVTyJ758eH5tvWBBecpu8TxDknj2

18ooViJEKTqf6TvfqzQuo71wLdnsg1EnXa

13XQo8CruU1KejcHXF3nobzvxzHdxVWJ33

There are 12 words in my seed.

I have only one wallet. I have never created others.

There are obviously two possible problems here which cause that wallet is show 0 balance. The first and most obvious is that seed is not correct, which means that even just one wrong letter reconstructs completely different wallet (different addresses). To exclude the possibility that you have wrong word, check that your seed is 100% correct by using this list : bips/bip-0039/english.txt

I found a similar case here, and it seems that in some cases wallet can be corrupted or there is a bug in some version of Electrum when user change password and then update to latest version.

One user is crack his "lost" password with Amazon Instance, and what he found is pretty strange. His password is changed, but he do not remember that he is set this password. Perhaps this can be solution of the problem : Strange Password Problem

[Abdussamad]

His seed is a valid seed based on what he's said above. It's an electrum seed and it was generated in jan of last year. Electrum seeds have a checksum in them so if he managed to restore his wallet using it there can be no doubt it's a valid seed.

I can only conclude that he either extended the seed with custom words/characters that he no longer remembers or that he never wrote down the seed for the wallet with the coins in it.

By the way, I want to say that this happened after the previous version of the wallet was not synchronized, I updated the wallet. And then it happened, the wrong password and not clear wallet when restoring

let's try to use previous version you have, but dont insert addres you have balance, look when sync or not.
or lets move your electrum file folder and redownload then use manually choose server look when sync.

previous versions are unsafe. don't encourage people to do unsafe things.

For a moment suppose you are right. Explain, then, as I enter my seed, I get access to the wallet?

Can anyone share developer contacts?

Maybe you created more than one wallet in the past and the seed you have is for a different wallet than the one with bitcoins in it. Did you create many wallets in the past? Were there problems with the storage drive (hard drive/ssd) of your win 7 laptop?

Ask for help on #electrum irc channel on freenode.

Created only one wallet for storage. Sometimes I went to check. No, there were no problems.

Why not try the Bitcoin recovery from here BTCrecovery and use the seedrecover.py in python?

and maybe there is a mistake from your seed that is why you can't find the correct wallet address.  The script above will help you find that wallet as it uses it for recovering a wallet if you don't know the exact phrase order or your back up phrase has a missing word.

[Ry4eek]

I found out: my wallet is 100%. Found one of the addresses (empty) of the old wallet coincides with the restored wallet. But addresses with a positive balance are missing. Even the master public key match.

[Abdussamad]

try 1c here

[WeirdRian]

I think that you had a non standard gap limit in your wallet and you had more addresses in the previous wallet.... just an idea though.

Maybe try to set the gap limit to 50 and see if any of the extra created addresses matches the old ones.
