In theory here it is solution:

Trustcoin, the company behind the 2fa, doesn't support BCH, so I paste what I replied to another user: 'I've seen that this worked for some.. In your electron cash wallet choose new/restore from your menu. Choose restore and choose make 2fa wallet, NOT standard. Import old wallet by enter your seed, it will confirm that it is a 2fa wallet and ask if you want to keep or disable, choose DISABLE. Hope it works for you as well.'

But unfortunately if I'm choosing enter seed, it's showing me Electron Cash termination because of error.. on second macbook it's just stucking in this place and after hours nothing is changing.. I have really problem and for me there are around 20bch to recover.. Will really appreciate for help.

So ... I have problem ..

Sound strange, but I've tried really everything and I can't send money from my wallet.

1) I have all private keys which are coming from electrum wallet . I have also all addresses (money are there)
2) I have passphrase.

1) First I wanted to do it through Bitcoin ABC - I could only import addresses. When I put private keys answer is "null".
2) Then I tried Electron Cash. Everything was great, cuz all bitcoin cash appeared, but then I couldn't send them anywhere. My account have "2nd step auth" and I see error (16: mandatory-script-verify-flag-failed (Signature must use SIGHASH_FORKID)) ..
3) So reading above I've used my passphrase to create new wallet on Electron Cash, disable 2FA . Then I have added all my private keys, but message was "no input found". - this is problematic now.
4) I wanted to file -> new/restore file and there put my passphrase to unlock my 2FA, but there is opening window "please wait".. and after hours still same..

So I really don't know what to do.

Can anyone help? I really have to solve it.

Thank you!

Hello,

I'm looking for business partner who has account on Bitstamp, Kraken, CEX, Gemini, itBit, Gdax, Coinbase, wherever where price is around 1450$ (for now) and who would like to trade with me. I'm buying 1-2% below those prices as many times a day as it is possible. Would be good to have instant transfer (fill up VISA, like CEX is doing - but I have no account there yet). If not then SEPA is also acceptable.. If you have account on CEX, we have really good business to do together. If we make e.g. 5 transactions per day and this is my minimum target then you are also making good percentage per day..
I'm looking for deals around 10 BTC (on first deals) up to 100-200btc later on. I'm not interested in trading 1btc.

Best Regards
Waiting for good business seekers!

I'm still fighting for it
Those keys are not what I needed to recover cash..

Thank you guys !

Because there were more helpers as soon as will receive bitcoins I'm going to send 50usd to apocalyptic and findftp !
Apocalyptic if you could send me your address on pm
Watashi, also thank you for involve but I'm using Mac : ) It's for sure good info for future people who will look for solution.

Hmm... already did all process until last point...

Is there any ready software which can allow me simply change this code through base 58 encode? or the best from priv key to wif? 

I mean, becuase if I have 100 private keys then it's going to kill my brain

Hello..
I lost some cash in my corrupted wallet.dat .. I'm trying to desperately recover it.. Already found many private keys in hex editor but have problem with importing them to bitcoin wallet.

I found that this is structure of private and public key

 // structure of a private key:
 // "308201130201010420" + private key (32 bytes) + " 2020101302c06072a8648ce3d0101022100ffffffffffffffffffffffffffffffffffffffffffff fffffffffffefffffc2f300604010004010704410479be667ef9dcbbac55a06295ce870b07029bf cdb2dce28d959f2815b16f81798483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47 d08ffb10d4b8022100fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364 141020101a14403420004" + public key (64 bytes)
 
 // structure of compressed private key
 // "3081D30201010420" + private key (32 bytes) + "a08185308182020101302c06072a8648ce3d0101022100fffffffffffffffffffffffffffffffff ffffffffffffffffffffffefffffc2f300604010004010704210279be667ef9dcbbac55a06295ce 870b07029bfcdb2dce28d959f2815b16f81798022100fffffffffffffffffffffffffffffffebaa edce6af48a03bbfd25e8cd0364141020101a124032200" + compressed public key (33 bytes)
 

My private keys are structured as compressed. If I'm adding it to my console as command:

importprivkey FC3F143D1C92B2054EC37DA0B491AAE37CE7BAA77A5F1577B17191D2F7936C01 (key modified due to privacy)

Then on output I have "Invalid private key encoding (code -5)"

How can I change compressed priv key to priv key? or just to wallet import format?
For help I'm sharing with 100usd as it's important for me.

A few questions:
1. You are not actually asking about sharing a *wallet* between users, just the block chain, correct regardless of the subject?  (Bitcoin Core, presumably)

yes I mean blockchain, u r right.

2. Are you intending to have both users running Bitcoin Core simultaneously?

that is also correct.

3. Are you talking about merely copying the downloaded data with the second user or actually sharing the downloaded block chain at the same time?

No matter which solution, just working. Tried first one.

A few notes:
1. If you used a bootstrap file, that is slower than actually letting it sync.  At least since 0.10.x.

oh.. didnt know..

2. If you copy (not move) the bitcoin folder to the new user and just let Bitcoin Core run there, that can save time.  You won't be sharing the wallet or the block chain between users.

To be honest I tried copying but the problem if I'm going to create bitcoin folder here ~/Library/Application Support/
and paste all data from copied blockchain it's not getting anything imported. More its updating bitcoin wallet once again and i dont even know where because for sure not in this path (after deleting folder it was downloading still but nothing appeared) and not in place where I set directory on main user.  Its strange..

Hello,

I have huge issue because must share my bitcoin blockchain through different users.
Just finished downloading all data on one user and to avoid downloading it again wanted to share it with different user (just need it very fast - today).
To share blockchain used applications folder (I'm OS X user) and copied all data to place where bitcoin should download files but before it started downloading (made backup before run wallet). Strange thing is that after creating bootstrap file there is nothing happen to import anything..
More, after I deleted bitcoin file from downloading location after running bitcoin wallet its running and downloading files but probably somewhere else? Don't know where because nothing was created after deleting my copied file with bootstrap.. That's true that I changed location of files folder on main user to documents/bitcoin but it's also not downloading it there as second user.

Really must to solve it in next hours otherwise have some problems.. Could u help me somehow import all data from first user to second user, so there is no reason to download all files again? Strongly appreciate.
