Please can anyone confirm that they have restored a Nano wallet on a Nano S without the black (security) card and are now able to release the funds?

As long as you have access to your 24 word seed, you can always restore your private-/public- keys.
The black security card is used as a physical 2FA as an additional security layer to the nano/wallet.
This card is only used to send funds from this specific hardware device. Its not related to your seed in any way.

You can import the seed into any BIP39 compatible wallet (e.g. electrum, can be downloaded here: https://electrum.org/#download).
Just choose to restore from seed and check the 'BIP 39 seed' option.

If you are holding quite 'large' amounts, i would recommend to make sure your PC is free from malware before typing in the seed. Better safe than sorry.


Note: Next time please start a new thread instead of hijacking/resuscitating an old one.

Thank you for replying I had tried this Electrum wallet restoration before, it didn't worth then nor now. The program freezes up while asking me to wait. I waited 3.5 hours without any progress from that point before noting this here. On another PC when I was attempting this the Electrum program just straight crashed repeatedly when trying to perform this function! I will try again tonight, but the Ledger info doesn't say anything about restoring a Nano wallet in a nano S Without the Black Security card cipher specifically. Honestly I have no further interest in trusting a product with any funds whatsoever that provides ZERO functional Customer Support for 3 weeks now. I'm not bagging, just pointing out how ridiculous this is on face value alone. This is supposed to be a legitimate company providing a legitimate product, how can this be the case when their products are not supported at all! I take responsibility for not having a card, that's not however the biggest issue here. The solution through their site suggested for this exact problem absolutely fails. This is wholly both illogical and unethical. This product takes funds without the black card and now holds them hostage without it. Since they chose to make the protocols to release the funds different from those necessary to deposit them, a working solution for this problem simply MUST be offered or they are absolutely not doing good business. This isn't any form of judgement, these are simply the facts. The wallet does not so much as mention any separate security card while taking funds, for it to now need this new external literature without any warning whatsoever is a clear cut product failure! I have been very patient and extremely diligent to find a solution, this is extremely stressful and it's wrong for Ledger to treat customers like this!

Please can anyone confirm that they have restored a Nano wallet on a Nano S without the black (security) card and are now able to release the funds? I won't keep a Ledger product after this nightmare, but I would buy a new one and use it and then resell it at a loss (especially now) to accomplish this.

The way this kind of hardware wallets works is that the keys/seeds are never exposed to the computer. When a transaction is initiated, the computer scripts the unsigned transaction and sends it to your ledger nano to sign. The transaction is then brought back to the computer to broadcast. This way, the private key is never really exposed to your vulnerable computer.

Electrum will not be able to restore the seed since it uses BIP39. You can however, convert it into xpriv and import into Electrum.

Electrum can restore BIP39 seeds as well if needed. You just have to click the option for it.

Do you know if the Ledger Wallet Ethereum can also support Tokens
 

ERC20 Tokens to more specific yes, I'm not sure If they support it directly from their Google chrome extension, If not, you could use Myetherwallet as they provided a tutorial about it: https://ledger.groovehq.com/knowledge_base/topics/how-to-secure-your-eth-tokens-augur-rep-dot-dot-dot-with-your-nano-s

I appreciate the detailed , I hope you don't mind If I use the quote from your statement in the thread I made. I also have another question , If It's impossible to recover using Electrum as It doesn't use BIP 39 then why the wallet gives you the ability to choose between Ledger wallet , Trezor & KeePey ? or that's only an alternative for this https://www.ledgerwallet.com/apps/bitcoin ?
I don't mind, that is my knowledge of how everything works and I may not be 100% correct though I am certain. Smiley

Since the seeds and everything are contained inside the device, Electrum just acts as a gateway for the transactions to be scripted. Electrum doesn't need to care what kind of seed it uses, Electrum just generates the transactions and help to broadcast it. Electrum doesn't touch the seeds or the keys.

Lets just imagine Ledger as a wallet and Electrum as the node that provides the information.

I'm speaking about all the versions (Ledger Nano , Nano S & Ledger Blue) here. I checked their support page : http://support.ledgerwallet.com/knowledge_base/topics/what-happens-if-i-lose-my-ledger-wallet It says that It's possible to recover your wallet using a BIP39 compatible software wallet and Electrum wasn't mentioned there and from what I understood from Electrum documentation , BIP 39 is not used on the seed unlike Multibit HD and Mycelium , so how come Ledger is supported in Electrum (I saw a few screenshots where you could choose Ledger , KeePey and trezor) when It's not using BIP 39 ?
I'm not using any hardware wallets for the moment and I only need this information's for the thread I made in service discussion (about hardware wallets) , I want to provide the most info for the users.
