How Stored :- Not Known
Source of transfer :- IRC
Bitcoin Address :- No
Wallet.dat file :- No
S/w used :- Bitcoin Core
How did you use Bitcoin Core if you don't have a wallet.dat file?
That makes no sense at all.
You can't receive Bitcoins if you don't give the sender a bitcoin address.
Pl Note :- I was asked to install a software which turned a normal hard drive to a nano ledger s.
It doesn't work like that.
The Ledger device uses a special USB hardware with a special firmware.
You can't just install the software on any USB.
I have used raspberry pi's (raspbian jessie) to see the coins
You can't see coins; Bitcoins don't exist at all.
They're just stored as UTXOs on the blockchain.
What you need to spend certain UTXOs assigned to you are private keys (they start with 5, K or L), if you don't have a private key then you don't have any bitcoins at all.
and validate its settings and it really does work
How exactly do you "validate the settings"?
What works?
![Huh](https://bitcointalk.org/Smileys/default/huh.gif)
but only thing is ,I am not able to take the bitcoins out of a text file.
WTF?
Bitcoins aren't stored on text files.
What exactly is on the text file?
Is it a string of alphanumeric characters starting with 5, K or L?
Post the first 3 or so characters.
Either you were scammed or you're trolling.
