please help

I sent from my old wallet Bitcoin QT to Electrum wallet and still didnt receive it nor it is back in my old wallet (10 days).

It seems like majority of the network has already dropped your transaction from their mempool. For Bitcoin Core, you need to manually remove the transaction before you can make a new transaction to send to your Electrum address.

To do so, open a command prompt and type either of the commands:
For 32bit Bitcoin Core: For 64bit Bitcoin Core: .

I dont know how to write " before C:\
I tried more options:

You have not to write the quotes, you need to paste or write it without the quotes like C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe -zapwallettxes

^^ you can see from my image i tried that first and it was not working

just use the run command (shortcut Win + R). same command unless you installed core on a custom directory.

this is still not solved. Whoever will offer solution that will work for me will receive 0.3 BTC from me

Judging from your post history you've been struggling with this since October last year?

Alternative solution:
In Bitcoin Core, click Help > Debug window > Console

IF you set a password, type this:
walletpassphrase yourpassword 600

THEN type:
dumpprivkey <address that holds the 6 BTC>
Import the private key into Electrum.

My Bitcoin address (https://blockchain.info/address/1PjpEgknyKxQKXtMcYFDym8odkfohFGkui) is in my profile (https://bitcointalk.org/index.php?action=profile;u=459836) :)

Ill give it a shot once my wallet is synced (167 weeks behind...), will be few days

Zapwallettxes is only available for Bitcoin Core 0.10 and above. That may be the reason why it isn't working?

Try updating it and trying my command again.

You don't need to sync Bitcoin Core to export a private key.

You started this thread in May, does that mean your wallet wasn't synced at that moment?

i have wallet Bitcoin Qt version 4.8.3, no idea what is bitcoin core



im installing old wallet on other laptop, i guess i will have to sync anyway since later i need to send those recovered 5.7BTC to my new wallet

clarification needed ... keep in my mind you have to exactly tell me what to do since im clueless  ;D
I found Help - Debug - Console in my Bitcoin Qt Wallet.
Why would I set password there? I know my password.
So I just use that dump command there?

That is the main problem here. Bitcoin Qt was the earlier version of Bitcoin Core and no one should be using a version that is that old. Go to https://bitcoin.org/en/download and you should be able to upgrade by downloading and installing a newer version.
I wouldn't recommend anyone that doesn't know Bitcoin a lot to handle private key by themselves. Anyway, if you really wish to continue, you are not setting your password there, you are unlocking your wallet.

So, key in:
walletpassphrase password843 600           

<To unlock your wallet with the password of password843 for 600 seconds>
dumpprivkey 1myaddressthatIwanttoexport

<To get the private key of your address.>

After this, just copy the private key (starting with 5 or K or L). You can choose to "sweep" the wallet and all of the value will be transferred to your wallet. Just go to Wallet>Private Keys and you should be able to sweep your address. Just paste your private key into the dialog and select an address by pressing the address button and it should be swept to your wallet.

Please make a backup of your private key before doing this. Consider trying to upgrade your Bitcoin Core first and use this method as a last resort.

this is how it went in console...  ???


17:20:58 walletpassphrase passwordXYZ 600


17:20:58 Error: running with an unencrypted wallet, but walletpassphrase was called. (code -15)


17:21:53 dumpprivkey 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgt


17:21:53 Invalid Bitcoin address (code -5)

That's not a valid bitcoin address. Where did you get that?
Also you can skip the walletpassphrase if you don't have a passphrase for your wallet (it's always recommended to use a passphrase though).

check my first pic ITT, it is the address i sent BTC to originally

It's not a valid address (https://blockchain.info/search/1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgt).
You don't need that address, you need the address holding the coins. That is the address where you sent it from, not to.

Judging by your whole story, and judging by how long you've been struggling with it: can't you get help from someone locally? Someone you trust, who knows what he is doing, and can help you just on your location?

no one local knows bitcoins at all. Can I find out address "From" when I sync old wallet? Will it show up there in transactions or somewhere else?

So 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgt is actually 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgT. Bitcoin addresses are case sensitive.


Your addresses with balance are listed under File > Sending addresses. Your screenshot shows that transaction so that means you've already synced. You should be able to see the from address you used unless you've deleted your block data.

Edit:
Hmm. You sure you didn't get the bitcoins to https://blockchain.info/address/16ukC1ftC1WLxmTmb8Wpi1vjKUAMoNpCk already? I see two 6BTC transactions and two 4.6999233BTC transactions which kinda look like double spends.

I think we're making progress.

This means you don't have to do "walletpassphrase".

nerioseole figured out what went wrong: the last t had to be a T.
Edit: steven0021 said the same, I had the page open for a while.

Now try this phrase again! If it works, import the private key into Electrum.

Do not post/screenshot the private key here!

That's a different address.

Yeah but double spend doesn't have to be spending to the same address and OP have sent btc to it according to the screenshot. Anywho it's just a guess for now.

01:01:10 dumpprivkey 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgT


01:01:10 Private key for address 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgT is not known (code -4)


"Your screenshot shows that transaction so that means you've already synced."
it was synced on old laptop that got reinstalled, i have backup of old wallet and need to sync again to be able to access File - sending addresses


"Hmm. You sure you didn't get the bitcoins to https://blockchain.info/address/16ukC1ftC1WLxmTmb8Wpi1vjKUAMoNpCk already? I see two 6BTC transactions and two 4.6999233BTC transactions which kinda look like double spends."
i did receive this payment 4.699 to new Electrum wallet, only last one 6 BTC didnt arrive and did not come back to old wallet (months time). And i did send last two payments (6.011 BTC - arrived, and 6.00 did not arrive) to exactly same address 1FFWn3rgS6JSREQvpSKr7P6AU5TUELjMgT

total 4 payments, it went like this:
25.2. sent 4.699 , received 25.2.
26.2. sent 6.00, received 26.2.
19.4. sent 6.011, received 20.4.
20.4. sent 6.00, DID NOT receive

So they're not double spends. All you should do now is resync bitcoin core and use dumpprivkey on the sending address, or just create a normal transaction again but with higher fee, I see you're using zero fee for the other 3 transactions and that can lead to a really long confirmation time (and ended up getting dropped).

You can't use dumpprivkey to get the private key of an address that does not belong to your bitcoin core wallet so doing that with an address from your electrum wallet or any other wallet you're currently using isn't going to work, and kinda pointless if it's an address from an electrum wallet that you still have access to and doesn't have problem sending from.

those 6 BTC are not back into my old Bitcoin QT wallet, how can I send it again ?
I was using dumpprivkey from old Bitcoin QT wallet obviously (but not synced one)... Sync will take a week since I can run it only during night because it slows down my laptop a lot

This won't work. Rescan will not do anything if the transaction is not already confirmed. Rescan merely scans the Blockchain for any transaction that wasn't included in the wallet. Since the 6BTC transaction wasn't confirmed, that transaction will not appear. If it hasn't been synchronised to the point where the 6BTC was sent to the wallet, the 6BTC will not appear.

OP, can you just update to the latest version and use -zapwallettxes? It would surely work. No risk of messing anything up, no confusion.

You will have to sync to see and to send since you don't know which address you used. If you don't mind only getting a large portion of your btc go ahead and try getting the private key of the address 1ABkfeKE28Jk1ZALiUAaK1W1miuabTkHsz (have 5.58810473BTC), 1AaQ8e41HE21wRNfQpegivcQUGCahSFfpQ (have 0.02BTC), 1Docw23ZiWJthC6zuKb2Xk9Q9AZZRrQY1t (0.01189527BTC). They're most likely yours.

Remember not to post the private keys here and just sweep it to electrum.

Just to clarify, is your bitcoin core wallet still showing the dropped transaction from your screenshot? If so you really should update and do zapwallettxes.

ok i had to send my backup . dat file to my friend and he solved it. problem was there was only 5.58 btc left in wallet, thats why 6 btc transaction didnt went through. My friend told me LoyceV gave correct advice, so I sent him 0.2 btc, enjoy&thx :)

Thanks :O
I just saw a popup from this transaction, which got me curious. Google brought me back to this thread.

Also: congratulations on finally getting it back! Price went up a lot since you started this thread.
And: very cool thing to tip me for this! I totally didn't expect that after this long :)
