Sweeping is just the same as "sending"... you cannot sweep a seed, nor can you sweep a master private key... you can only sweep individual private keys.
So, first up, create a new Electrum wallet -> "standard" wallet -> Create new seed -> WRITE THE SEED DOWN!
Now, you're ready to get all your coins from Mycelium to Electrum... you have two options:
1. Open Mycelium, send all your coins to an address from your new "seeded" Electrum wallet
or
2. As jackg said, Create a new wallet -> call it "restoredMyceliumWallet" -> "standard" wallet -> I already have a seed -> enter the seed, click the options buttton, select "BIP39" -> When prompted, leave the derivation path as: m/44'/0'/0'
(NOTE: This will recreate your Mycelium wallet... however, it will ONLY recreate the first "account" from Mycelium, if you had multipled accounts, things get a bit more complicated.)
- Once the wallet is recreated, you should be able to see all your transaction history, addresses and coins.
- Now send all your coins from their to the receive address from your new Electrum wallet.
All your coins are now in an Electrum "seeded" wallet.

I really wish all this FUD about ElectronCash would just stop... it's opensource... it's clean... it's safe... This thread should be locked.  To the best of my knowledge. Not one single person who downloaded ElectronCash from the OFFICIAL site: https://electroncash.org/#download has lost either BTC or BCH because of something that ElectronCash has done.It is NOT the fault of ElectronCash dev's that people are stupid and download scam versions of the software from scam sites... or they're careless with their private keys/seeds... or that they have pre-existing malware/keyloggers on their computers. Take the proper precautions ie. move your BTC to a completely new wallet, not just new addresses... a completely new wallet with new seed... BEFORE you try and get your BCH and you will have no problems. I've been running ElectronCash since it came out in August... ALL my BTC and BCH are still safe. |

"Don't believe everything you read on the Internet" -- Abraham Lincoln Did you even read ANYTHING after the first post in that read? If you did, you'll notice that it was just a minor issue with ElectronCash connecting to BTC servers and displaying the incorrect transactions. To the best of my knowledge... No one who downloaded the "official" ElectronCash ( https://electroncash.org/#download) has lost either BTC or BCH because of something that ElectronCash has done. It has been around now for almost 4 months... if it truly WAS untrustworthy... we'd know about it by now. Usually it is because they've downloaded a scam version of the software from a copycat scam site... or they have been careless with private keys or seeds... or have had malware/keyloggers present on their system. I've been using ElectronCash since it came out at the time of the fork... all my BTC and BCH are safe. |

No... that just means you failed to give it a mandatory option like --wallet or --datadir or --dumpwallet etc  Mine does the same thing when I just type "pywallet.py" with nothing else If you type: or You'll notice it doesn't give you that message I'm fairly sure that bsddb is included with Python, installed by the other components or isn't strictly required. I don't remember ever installing it separately... only the default Python 2.7... and then used the install.bat in the pywallet directory after I extracted the files. Unless you specifically see an error message that says something like "no module named: bsddb" then I don't think it is an issue. Just try running the recovery and see what output you get. |

No, you don't need to transfer the confirmed transaction to your offline PC (if you're using an "airgapped" offline PC setup). All the offline PC is used for is "signing" transactions. When you create a transaction on the Online PC and transfer it to the Offline PC, it'll include ALL the information the offline PC needs ps. one piece of advice... unless you are super comfortable using "mBTC" aka milliBitcoin units... I would suggest going to "Tools -> Preference -> Appearance" and changing the units to "BTC" and set the decimal places to 8 NOTE: you may need to close the preferences window and re-open it to be able to change the decimals to 8 |

Do you need v3.0.2 for any reason? If not, try v2.9.3 and see if that works... https://download.electrum.org/2.9.3/It might be that even though you managed to get v3 to start on Win7, it might still not be functioning correctly. |

You can't just export the private key from a 2FA wallet... it is a multiSig... it has 3 keys per address. You'll notice that the imported address is now a "1" address in Electron Cash. This is why your final balance is 0... it is a different address.
To get an Electrum 2FA wallet into Electron Cash... you need to:
1. in ELECTRUM... File -> New\Restore -> Give it a unique name like "disabled2FAwallet" -> Wallet With Two Factor Authentication -> I already have a seed -> Enter the seed for your 2FA wallet -> select "DISABLE" when prompted to "keep or disable" 2FA functionality
- This will create a copy of your wallet file with TWO private keys in it.
2. in ElectronCash... Open the "disabled2FAwallet" file that you created in Step 1.
- You should see all your "3" addresses and correct BCH balance.
You can now send your BCH where you want.

If you sent the BTC to your nano, it's likely that somebody replayed the transaction onto the BCH network, unless your ledger was using a segeit address.
That's actually impossible... BCH has full 2-way replay protection... BTC transactions are not valid on BCH network... BCH transactions are not valid on BTC network. To get your BCH: Download Electron Cash (a Electrum fork for Bitcoin Cash), import your old Electrum wallet and send your BCH to your Nano S Bitcoin Gold address.
errrr... I really hope you meant Bitcoin CASH address!! haha... Man, so many "Bitcoins"... gold, cash and now diamond... getting confusing!  In any case, I'm pretty sure that you CAN'T accidentally send to a BTG address... they changed the address format, so it SHOULD get rejected. |

Slow but steady progress... hopefully this time, the recover process will actually be able to decrypt the keys it finds in the wallet file... so that the recovered_wallet.dat is able to be dumped properly |

Try creating a file that just has: And see if that works with your wallet file that has the password "tes"... it should test ALL passwords with 3 characters... including lowercase, UPPERCASE, numbers, but excluding symbols. It should generate a few thousand guesses... but should find "tes"... otherwise, you're not running btcrecover correctly. What command are you using to run btcrecover? |
|
|
|
But then, in my last try, I got a blank space after entering enter. So I tried the same password again, and got the same blank space.
So do I have the right password?
If you see something like: "null" after you type in the walletpassphrase command and press enter... Then yes, it sounds like you do indeed have the correct password...  I had some special characters in the password, but I didnt need to put in marks in the console of that reason.
Might just be if you have a space in the passphrase then... Anyway, glad you managed to figure it out. Good luck with rescuing the funds... just follow TryNinja's suggestion exporting the private keys... and importing them into Electrum. |

Huh... I guess your Python is NOT installed to C:\Python27 then... do you happen to know where is it installed to?
Can you do a search on your computer for pip.exe?

Hey guys, I have been in the forums for quite a while and I noticed that long transactions has been one of the most issues of users nowadays. I am offering a FREE transaction accelerator.
ORLY? "Date Registered: 2017-10-28, 03:52:00"  I know your service is "free" and all... but being here like 4 weeks and claiming to be a long term member while fishing for "tips", most likely by using free accelerators like AntPool and ViaBTC and confirmtx?? |

You can "steal" coins from Electrum with any combination of: 1. The Seed 2. The wallet file and wallet password (if password protected) 3. The wallet file (if not password protected) 4. Private keys If someone else has any one of those, your coins are effectively gone |

Please post the real transaction ID to prove your claim.
It IS a real transaction ID https://blockchain.info/tx/4910d016caed9c447652e0a372f73b9acc262f2a957db1fe85544b33baf65523You'll also notice that it paid a fee of: Fee per byte 463.422 sat/Band it took 1,135 minutes to get a confirmation: Included In Blocks 494114 ( 2017-11-12 23:04:46 + 1,135 minutes ) Take a look at those users. They are all newbies, and possibly made to troll us.
Nevermind the newbies... it's the Sr. Members, heroes and legendaries who don't seem to know some BTC basics and are likely "bought" accounts that bother me |

Bitcoin network is operating fine... it is most likely an issue with your setup or network... Which Bitcoin wallet exactly? Bitcoin Core?
If so, did you go into Settings -> Options ->Network
Is uPNP selected? what about "allow incoming connections"?
Is your machine connected to a VPN? Is it behind a firewall?

3. I contacted their support and their response was: "I'm really sorry but it is considered invalid because it was less than 0.01. If it is below 0.01 the blockchain takes it in as a fee and won't update the tokens." Are they actually helpless, or have they just stolen my money? To be fair, it was my fault for authorising the transaction at an amount less than the minimum investment.
This is pretty much bullshit... the "blockchain" doesn't take anything as a fee. Those coins have been assigned to a private key which THEY are in control of. They may not consider your investment valid as it is below 0.01 BTC, but they can sure as hell access those coins and send them back. If they don't they're basically treating your payment as a "donation", which is an expensive lesson to learn... and a bit shit on their behalf. It probably makes no difference in the long run because, as cpfreeplz has already mentioned, you should NEVER fund ICO's directly from Exchange addresses... fairly sure Bittrex even have a warning about this: Do not withdrawal directly to a crowdfund or ICO. We will not credit your account with tokens from that sale.
So, you likely never would have got the tokens anyway 4. I used the 'extended public key' on my hardware wallet which then generated a barcode that I scanned in to MyCelium. I then scanned the MyCelium barcode at the ATM. Funds seem to have sent, but they're not appearing in my balance on my hardware wallet.
What wallet app are you using? The Ledger chrome app? If so, did you select "Legacy" or "SegWit" chain? |

You have created a "SegWit" wallet... Electrum generates "bech32" SegWit P2WPKH addresses (that start "bc1") which are not backwards compatible with a lot of wallets... instead of the more common and fully backwards compatible SegWit P2SH-P2WPKH addresses that start with a "3". Refer: https://bitcoincore.org/en/segwit_wallet_dev/If you want to use SegWit, you'll need to use a different wallet for now until bech32 addresses become more commonly "accepted". If you want to continue using Electrum, You'll need to create a "Standard" wallet... and select "Standard" instead of "SegWit" |

It also needs it "fee" functionality to be revamped with the ability to either let you specify custom fees or to at least use fees that are relevant in todays bitcoin environment. It uses "fixed" fees that are often WAY to low to get transactions confirmed in a reasonable length of time (if ever) |
