Which one, actually, you ask? How to restore a wallet or how to restore someone's wallet?
Because if you are asking for a procedure to restore a wallet, we have some guides here, but it depends on what wallet. Is that Electrum, Bitcoin Core, or any other wallet?
Adding more details can help us to know if that wallet is recoverable or not.
If that's other people's wallet, you should have some experience before offering a recovery service.
I’m talking about restoring my personal wallet,I will like to have the guides you have so I can restore my wallet and it is Electrum and I stored my bitcoin in a Trezor cold storage wallet.
You should probably start by telling us the kind of wallet software you used back then to keep your Bitcoins. What's the file name or file extension of the wallets files (this could give a clue about the kind of wallet software you used)
Did you encrypt the wallets? If you did, you might want to remember the passwords you used back then.
It’s a Electrum software and I still remember the password I used back then, I jus need some detailed steps and procedures on how I can restore the wallet.
Is it fair to assume that you didn't make a backup of your seed? If you have your seed and optional passphrase and know the derivation paths where your bitcoins are (in case they are non-standard), then you don't need the actual wallet file to recover your coins. Bitcoin Core is an exception to this rule.
If the wallet file is encrypted with a password, you will need to remember it to decrypt the wallet. A password can perhaps be brute forced if it's really simple or if you have a good idea of what it was and perhaps you are only missing a part of it. If it's a really complex and long password with all sorts of characters, it might be an impossible task.
Probably yes because the wallet was missing almost five years ago, what I need currently is jus the procedure or guide I can possibly use to easily recover my wallets and have my bitcoin back..
