2521  Bitcoin / Electrum / Re: Old wallet Electrum 3.0.3.0 and Android JellyBean 4.3 on: October 25, 2021, 10:59:24 AM
.
Problem is, the version in the website may be different than what they've released in Playstore so you might encounter errors during installation.
Probably Jellybean might not support the latest version, few days after the latest version is released on electrum office website, it will also be taken to playstore, and just only the latest update unlike the Electrum official site that you can still downgrade the app to electrum previous version.
I shouldn't have used the word "version".
I mean, the "release version" apk's may be different than the uploaded binaries in the Playstore.
If those are different, it might fail to install-over the currently installed old version.
2522  Bitcoin / Electrum / Re: Old wallet Electrum 3.0.3.0 and Android JellyBean 4.3 on: October 25, 2021, 06:05:31 AM
Can someone help me with a step by step on what version would I need that can run with 4.3 jellybean and how to  actually update the wallet?
I don't have an old Android jellybean device to test but, you can check which version will work from the downloads archive page of Electrum:
Link: https://download.electrum.org/

The lowest version that can connect to servers is version 3.3.4, download the file "Electrum-3.3.4.0-release.apk" and install it to your phone.
Problem is, the version in the website may be different than what they've released in Playstore so you might encounter errors during installation.

how i can Make sure Bitcoin Core's prune setting is disabled ?  

this is size storage in my computer - https://ibb.co/yqndVtj
I see, so the main disk doesn't have enough space for the blockchain that's why pruning is enabled.

You can use your 'disk D' as the data directory then disable pruning in Bitcoin-qt's setting:
  • Open Bitcoin Core (bitcoin-qt) and open the settings: "Settings->Options..."
  • Click "Open Configuration File" below and 'bitcoin.conf' will open using your notepad.
  • Type/Paste: datadir=D:\Bitcoin into that text file, save it, then close it.
  • Lastly, uncheck "Prune block storage to" to disable pruning (I have already told you this when you're just starting the sync process).

Restart Bitcoin core to reload the config file and it will sync from scratch after that.
That's all you need for now, wait until it's fully synced, then you can always use importprivkey to your 'blank wallet' if you found more keys.

how i can add 4 keys in bitcoin core to check ?
-snip-
how about if the 4 keys encoded by MD5 ?
If those are hashed with MD5, then you wont be able to reverse them easily since it's not reversible.
MD5 is broken so you may be able to bruteforce or exploit the vulnerabilities but that's a job for experts in that field.

If those are HEX, do the same procedure that you did to the previous four keys in the OP to encode them into WIF.
Then import it to your "blank wallet" using the steps I've mentioned in my previous post.

Make sure Bitcoin Core's prune setting is disabled so you can rescan after it's fully synced or you'll just waste your internet bandwidth and time.
2525  Other / Beginners & Help / Re: Bitcoin core slow-Stalls while updating? on: October 24, 2021, 03:53:14 AM
Thanks I will give that a try, but what does that tell me, when I run it.
There, you can find "Error:" and "Warning:" lines of text that will tell the reason why your Bitcoin Core is stuck at 89%.

Additional info: Windows10 may not be able to open a ".log" file directly as text so, select a text editor (like notepad) when it prompts you.
The debug log will be saved in the data directory, if you're not using the default - %appdata%/bitcoin, you should look in your custom bitcoin data directory.
2526  Other / Beginners & Help / Re: I need help with hexadecimal keys on: October 24, 2021, 03:43:11 AM
Hmmm... unfortunately, I don't know how the old bitcoin.com worked and I have no idea about an old "China site" where you bought the bitcoins.
Armory is another Bitcoin client that only uses Bitcoin Core to download and verify the blockchain, here's its board if you want to know more about it: /index.php?board=97.0

-snip-
I knew its complecated and many thinges and i have file name ( DaYi ) same ( array file ) !
It's complicated alright  :-X
Anyways, if those "four keys" are the same ones you've imported to Bitcoin Core, then let it sync so it can find the coins.
Bitcoin core is capable of checking all outputs of different script types derived from the private key.
If Bitcoin Core has fully synced and it has no balance, enter rescanblockchain command for the last time to make sure that it's really empty.

Other than that, I have no further response.

Hi man - i got this - see the pic
<image edited out | broken link>
It means that your blockchain is set to be "pruned", it can't use rescan because it doesn't have the older blocks because 'pruning' will delete the older blocks after the set size was reached.

I don't know if it will be able to scan for balances (from the succeeding blocks) of your newly created wallet's imported keys because I haven't experienced that scenario.
If you have enough disk space for the blockchain and other data (about 400GB+), you can consider disabling pruning in "Settings->Options...->Prune block storage to".
Then restart the sync process.

Plus you need the whole blockchain in case you'll need to import other possible keys from your backup in case those four aren't private keys.

at first i use private key start with 5
the secound use privatekey wif Compressed start with L
The order isn't important, the important part is to use the rescan flag only in the last key.

another issue is that I have my blockchain downloaded on my ssd drive, i do the bitcoin-cli datadir to it, it connects but bitcoincore is still downloading the blocks to my home folder. I am unsure how to stop this other download.
I have my blockchain downloaded on an ssd, so I routed the bitcoin core gui to read from the ssd, it connected and synced and is running.
That's because the start parameter you added to bitcoin-qt wont be used by bitcoind or you're using it with default start parameters.
You mentioned that you've used the GUI to set the custom data directory.

Anyway, to make a global default, add datadir=YOUR_SSD_DATA_DIR to your "bitcoin.conf" file in the default data directory.
If you don't have a bitcoin.conf file there, create one.

Default bitcoin datadir: https://en.bitcoin.it/wiki/Data_directory#Default_Location
2529  Bitcoin / Electrum / Re: Help with my Electrum wallet on: October 23, 2021, 03:45:08 AM
Hi all,

I used the original seed to restore the wallet, as that of the wallet I sent the btc from. I've read that I should try change servers on electrum but I'm not too sure how to do this?
To change server:
Click the green circle icon at the lower-righthand side of Electrum,
Untick "Select server automatically", then right-click on a server of your choice and select "Use as server".

But if it's already green, changing the server wont be needed.

Quote from: Dwolmarans
It's been two days and the btc hasn't reflected in the receiving address and still nothing is showing on my electrum wallet.
-snip-
I will also try check the different wallets like suggested. On this pc it is the first time electrum has been logged onto it
It's been two days but have you let Electrum open for a while and did not closed it right after checking the balance?
Because it needs time to download the blockchain headers.

If nothing checks-out: I highly suspect that you're looking at a different wallet file, if no, restored a different seed.

after Blank Wallet name wallet i have 4 choices ?
No, I mean select the second choice "Make Blank Wallet" not 'blank wallet name', you should put a wallet name or 'Create' button wont be clickable.

After creating the wallet, go to console (Window->Console). Select the blank wallet in the "Wallet:" drop-down menu.
Then type the commands, one at a time;
For the first three:
Code:
importprivkey "Your_Private_Key" "" false
For the fourth key:
Code:
importprivkey "Your_Private_Key" "" true
Change "Your_Private_Key" into those encoded WIF private keys.

i didnt understand If you use Electrum, let the wallet open for a few minutes for it to sync (blockchain headers - 55mb file).
its open fast and i try all keys says 0 and try one of them says same thing 0
Electrum needs the blockchain headers to function which it doesn't have initially.
So if it's the first time Electrum is used, it will have to download the said file which is about 55mb in size so you'll have to wait for it to be completed in the background.

But if about 10 minutes have passed, your internet is "good" and the Electrum's connection status is 'Green' (lower-right circle),
then the imported WIF keys are really empty (at least for P2PKH outputs).

I bought them between (2009 - 2012) Procedures may vary  Huh
It barely reached the year when compressed public key was introduced to Bitcoin client,
If it's before April 2012, you shouldn't be looking for compressed addresses because it's not available in the client at that time.

You may have to search for P2PK outputs as well, which doesn't have an address but the public key itself.
IDK any other client that support it aside from Bitcoin Core; if you want, you can import those keys to Bitcoin Core but it will require you to download and verify the blockchain before you can check for balance.
Your transactions are quite early so you'll likely see the transactions earlier in the sync process if it has any balance.

Import command (do right after creating a "Blank Wallet"): https://bitcoincore.org/en/doc/0.21.0/rpc/wallet/importprivkey/
Use "false" rescan flag for the first three, then "true" to the last one.

finished and all they start 5
You can now import those to a wallet of your choice, or my suggested client: Electrum.
If you use Electrum, let the wallet open for a few minutes for it to sync (blockchain headers - 55mb file).
If there's no balance, those may not be private keys or those are for compressed public keys, in that case, use the tool in the post above.
2533  Other / Beginners & Help / Re: I need help with hexadecimal keys on: October 22, 2021, 04:50:15 AM
One by one; pasting them all will produce invalid result.
The result should be similar to the WIF (Wallet Import Format) displayed in the linked thread above, it should start with '5'.

A wallet can import/export multiple private keys, you may have exported those 4.
2534  Other / Beginners & Help / Re: I need help with hexadecimal keys on: October 22, 2021, 04:31:14 AM
the next step is base58 or ?
Yes, if those are private keys, the next step to be able to import those to a wallet is to convert them into WIF (base58check).
The easiest way is to use a converter tool.

This one should work (brainwalletx.github.io/#converter) but must be used in an offline environment and downloaded & run from source.
To convert the keys, go to "Converter" tab, copy your PrvKey (HEX) into the "Source Text", then select "B58Check" in the 'Convert To' tabs.
The result should be the private key in WIF format, depending on the age of those keys, you may or not need to convert them into compressed WIF.

Then import those keys to a wallet, I'd suggest Electrum (electrum.org).
Here's the steps to verify Electrum (recommended before using it): https://bitcoinelectrum.com/how-to-verify-your-electrum-download/
Here's the steps for importing keys: https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/

Note: Do not share the private keys.
2535  Bitcoin / Electrum / Re: Help with my Electrum wallet on: October 22, 2021, 04:10:02 AM
-snip- I then logged onto my main pc but it doesn't show any transactions in my history how can I recover this?
my btc doesn't show in my electrum wallet so that means it hasn't been sent back for not being confirmed.
Bitcoin transaction don't work that way.
If it wasn't sent at all, the coins wont be moved and the previous inbound transaction should still be displayed in the wallet's history.
In an event of dropped transaction, Electrum will just show it as "local transaction" (blue computer icon) that can be easily removed from the history using right-click menu.
But being dropped from mempools is a rare occasion.

If there's nothing in the history, I think you're looking at a different wallet file, Electrum can have more than one wallet.
Try to check your other wallet files in menu "File->Open" or "File->Recently open".

If you meant by "restore the seed" by saying "logged onto", and it's the first time Electrum was launched in that PC.
It may need a few minutes (55mb file) to sync depending on your internet speed.

ECDSA Private key in HEX should be 64-characters.

Read this thread to know about the other possible private key formats, specifically the part about "Bitcoin private keys":

I am on the BTCarmory.com site. I clicked on the link for the signing keys (Armory signing key (4922589A).) and it comes up as a bad request? -snip-
That page in BTCArmory is pretty old and keyserver.ubuntu.com must have updated its URL scheme for search queries.
The current working link should have at least "&op=index" after the original link.

So this link should work: keyserver.ubuntu.com/pks/lookup?search=goatpig&op=index | original link

-snip- When I open the electrum app I have my default wallet and another wallet which contains my Bitcoin. It says I have 1.1912 mbtc. I believe it's about 80 bucks. But for the life of me I cannot figure out how to move it out of there.
I believe you're aware of the 'send' tab since it's pretty much fool-proof and you've managed to send from Coinbase to Electrum.
So what's the actual issue? Can't send the full balance when sending it out; or Cant send at all?

What's written inside the '[]' after your main wallet's 'wallet name' in Electrum's title bar?
[2fa], [imported, watching only], [standard, watching only] or [standard]?

copy the wallet you want transfer to > press send > paste the wallet > press send and confirm with your Electrum password
Correction: Wallet = Address

What is "the addresses are not covered by the user’s seed phrase” and how to deal with this matter?
It means that your backup phrase (seed phrase) wont be able to restore those addresses (like what's happening).
IDK but it could happen if you've encountered client-side issues like errors/corruption that made it produce addresses from an 'entirely different' or 'randomly modified' master key.
But no one knows if it's what really happened when you created those 7 missing addresses.

Quote from: NatalyDNA
Is there any possibility to find support from somewhere else and pay for this issue to be checked, explained and solved on my behalf?
They won't be better than blockchain.com's support or this forum since no one has full access to your wallet.
You'll likely get the same response from this thread.
Worse case is, you might be contacted by some scammers that pose as their support that will likely give you false hopes then demand a "fee" for the supposed "recovered bitcoins".

Blockchain.com's support wont be much of help since it's a non-custodial wallet (they claim). (Github Repository | note: I haven't reviewed it)
They can only help you with the custodial parts of the wallet (eg. Trading wallet); login & balance update issues - things involving their encrypted/watch-only copy of your wallet in their database.
