Not sure if you're aware of this, but your tx has an empty scriptsig, maybe that's the issue.

(Just a wild guess)
2  Bitcoin / Electrum / Re: Problem with my wallet on electrum ""Cannot read the file" on: September 24, 2025, 02:46:42 PM
The version of electrum is old from 2018. I made an upload on the official website, and then i can't access my wallet anymore since this day.

There are some text but no "seed" found. It's not a hardware problem. It's when the upload has made, some of us, had this exact problem.

I try to contact many times Electrum, they never answered. Its the version of electrum in 2018 who was corrupted. I install it and realize it was too late.

I don't have any chances ? Some people contact me, telling me that can do it , with contrat, asking me 20 % if they succeeded.

It's true ?

Have you been able to verify (using an blockchain explorer) that the coins are still in your addresses and did not move since 2018?

Attempting to bruteforce the password (using a *strong* multi-GPU rig) might work, assuming the file is an Electrum file and the password is not too long/complex.  Over the years I managed to help other users recover electrum passwords.   See this case where I was able to help another user recover their coins last month:

https://bitcointalk.org/index.php?topic=5228226

Feel free to DM if you would like me to give it a try.  I typically need as much information as possible to get started.

Note: I will be quite busy in the next few days, and might not be able to respond quickly.  
Note: Be very careful not to answer DMs from random users.

hi, i have it inform of a qrcode with pasword below.

i hav a wallet.dat file  which has a form of code that i dont underwtand, its more in the form of symbols than lettrs or digits

Before going any further, as a safety measure be sure to make several copies of the wallet.dat and password to avoid losing them again.
Also beware of any scammers trying to contact you by PM. 
4  Bitcoin / Electrum / Re: How do I connect to servers? on: September 07, 2025, 12:52:02 PM
I did he AV stuff. Electrum not listed as a threat. And I switched the AV protection off and started Electrum, and still not connected.

But I found the log files and inhem is this:
interface.[ex.btcmp.com:50002] | disconnecting due to: ErrorGettingSSLCertFromServer(ConnectError(ConnectionRefusedError(22, 'The remote computer refused the network connection', None, 1225, None)))

So it eems the remote servers listed by Electrum are refusing to connect to my computer.
Do I need to have my Electrum verified or authorised? By using signatures?

 

You could try to add some of the servers to your hosts file
See:  https://github.com/spesmilo/electrum/issues/4940

(or try from another computer if possible.)

In any case, it looks like something specific to your system. 
Electrum has been rock solid lately, no downtime for the last few weeks / months.

5  Bitcoin / Electrum / Re: How do I connect to servers? on: September 04, 2025, 04:48:32 PM
Button is red

No special network  

When I change from auto-connection to manual selection and select a server nothing happens or changes, ecpt the name of the servere in the server field changes to to the server I selected

Try right-clicking on a server in the list and click "Use as server".  The network icon should turn green.  If it doesn't, check if your AV or firewall is blocking some outgoing connections.

Also, can you confirm what version of Windows and Electrum you are running?

Bruteforcing the password (using a strong GPU setup) is feasible if the password is short, but I wouldn't bet the farm on it.

Over the years I managed to help other users recover their wallet passwords, using my GPU rig - of course, this is only feasible if the password isn't too strong.  My most recent successfully recovery was this one (Electrum password):

https://bitcointalk.org/index.php?topic=5228226.20

My fee is more reasonable and backlog shorter than some of the larger recovery companies. Happy to provide more detail by PM.
 
Note that the more context information you can provide, the better the odds of success. Also, I don't work on stolen wallets.
7  Bitcoin / Bitcoin Technical Support / Re: Bitcoin node 2009....HELP. on: August 30, 2025, 03:51:52 PM
I have a bitcoin application from 2009.  I would like to try to get it running again to see what's in it?  Any help?  I have it saved on windows 7.  It was last accessed via VM on windows 7.  I believe the file to be from Windows XP or from windows vista.  I have a block with the corresponding signature and id like to use atleast one for my family.  Anyone willing to help?

Post screenshots, post signatures if you want effective help.
Vague statements are a waste of time for everyone.

So anyone able to help me figure this out its on an old legacy wallet from a wallet.dat file of mine and I did encrypt it but can most likely hash the password I put I have a good idea on what it may be but if you know how I can bypass this I will give whoever 10k reward its been so long since i messed with this stuff an I was way smater back then.

https://www.blockchain.com/explorer/addresses/btc/1ApiCgLSysQFeF7V2MFTEHiRsep7AR8Pyx right here is the wallet I got from a dump on receiving addresses on the .dat file for proof

Did you have any luck recovering this?
 
If not, feel free to shoot me a PM - FYI I managed to recover a long-lost wallet password for another member just a few days ago (using my multi-GPU setup).

Thanks!  I'd rather not provide a lot of detail on specific cases, but in a nutshell the first challenge was to manually reconstruct the damaged wallet json to be valid. Once that was done, password recovery was rather quick (using my multi-GPU setup), as I was given some pretty helpful hints, and the password itself was not overly complex. Even pure brute force probably would have cracked it as well.

I'm happy to announce that I was able to complete bb3456's wallet recovery!
 
Btc has been recovered, after being stuck in limbo for almost 10 years.  
The job was a technical challenge on several levels, but it all worked out just fine in the end.

@bb3456  Many thanks for your trust, and the very nice fee.

Confirmed, I was able to make a 0.3 sat/vB tx using this server.
I don't know how you got it to work because it didn't work for me. After I switched to the server, I saw the usual notification that the server won't broadcast my transaction when I set the transaction fee below 1 sat. I restarted Electrum a few times but that didn't work either. When I closed the send tab a few times and opened it again, it allowed me to enter a few below 1 sat/vByte without that notification popping up and the "preview" button became clickable. But what I noticed was that the equivalent amount in USD was as if I had set the fee to 1 sat/vByte. The wallet didn't lower it regardless if I set it to 0.7, 0.5, 0.3 sats, etc. There was also a notification next to the total fee that said "xxx amount of sats will be added to the transaction." It always added enough to make the fee 1 sat/vByte.

Are you sure you didn't see the same and you just think that you broadcasted the transaction at 0.3 sat/vByte when in fact you didn't?

I tried another 0.4 sat/vB tx to be sure, and it just worked. I'm not using a custom build of electrum or any unusual settings.

No idea if I'm just lucky or something. Smiley   This is the server I'm currently connected to: electrum.pabu.io:50002

This is what I'm starting to discover.  Since I really don't have any idea what the password was, I can't really start a tokens file or password file.  running this on my laptop, or even PC isn't realistic.....


Do you take less than 20% to try?  I'm basically looking at WalletRecoveryService, as it's the only chance I have (not knowing my seed words either).

Sure, just sent you a DM

Do you remember anything about the password that was used? Length, special symbols, randomly generated or not, etc.
I successfully recovered an old wallet of mine using hashcat, but it does have a bit of a learning curve and needs a good GPU setup.
