I have 2 wallets in Multibit HD, had already made transactions through them and suddenly I can not "unlock" the wallets. Although I use the correct password and words, the application gives error with the message "The password did not unlocked the wallet".

One of the options is to recover the wallet but although using the passwords and words correct also gives error, does not create the new wallet. Everything that tries to do will give the same error related to wallet, does not unlock.

I sent email to multibit, they told me this is a known bug and advised to import these wallets by Breadwallet or Bitcoin core. But all options to import request the "private keys" from my multibit wallets but unfortunately I did not write down, do not know where I kept these private keys, do not know where they are and how to recover them by multibit.
 
Cause I can't open my wallets by multibit I ask you

how to recover private keys from these wallets created by Multibit that I can't unlock?
What is the procedure for importing these Multibit wallets by Bitcoin core?

I appreciate any hint you sent.
Grateful.

To recover your MultiBit HD "wallet words", you can use: https://github.com/gurnec/decrypt_bitcoinj_seed

You will need to install "Python" as per the instructions on github, make sure you install version 2.7.x of Python... NOT Python3.

Once you have your Wallet Words, you can restore your wallet using "Breadwallet" (iOS or Android) or "Simple Bitcoin Wallet" (Android). These are currently the only two wallets that I know of that are compatible with MultiBit HD seeds/"wallet words"

NOTE: As far as I'm aware, the wallet is not compatible with Bitcoin Core? Huh

Thank you HCP for your response but what I lost was the private keys of these wallets.....the wallet words I've got stored in a encrypted file. It's ok.
I've already downloaded Breadwallet but I need to complete the recovery of my private keys first. I don't even know what else to do.
I appreciate anything you could do for me. Thanks.

No... you don't need to worry about the private keys. If you have the wallet words, then the wallet software can automatically regenerate the private keys using those words. That is the whole point behind HD wallets Wink You will only need the private keys to access your coins if using Breadwallet (or Simple Bitcoin Wallet) is not an option and you need to use different wallet software.

Just put your 12 word seed into Breadwallet and it should regenerate your wallet with the same addresses and transaction history and balance.

Wallet words look something like (12 'random' english words):
common witness right fence monster venture brick wood nominee deliver entire tongue

Private keys (in WIF format start with a 5, K or L) look like:

#greatSuccess Cool

Just for the record, if you recovered to Breadwallet... I don't endorse or recommend this wallet for long term storage. I haven't used it past some very basic testing... and mobile wallets on a mobile device are just "lost" bitcoins waiting to happen in my opinion (lost/stolen/damaged device)...

I would recommend that you send your coins to another (more secure) wallet for long term use... but that's just me Wink

I agree HCP, all the wallets I've tried have some kind of problem. I tried breadwallet only to import my lost multibit wallet. By your experience, which one would you suggest me? And don't worry, everything will happen at my own risk. I appreciate your attention.

For the past 2 days i thought i lost them all. No words, zip.aes not working. aes file corrupt.
BUT, I just managed to recover 100+ BTC today after crying for a day and working for the past 48 hrs.
The solution was rather so simple at the end. I will make a thread about it to help the rest.

But stop using Multibit HD. I cannot stress this enough.
One day it's working fine, the next boom...gone...dead...locked.
