Hello guys,

I faced a problem with my ledger, it failed and doesn't work after I tried to update it to version 1.4.2 via Ledger Live.

Short summary what happened.

I never updated ledger before due to different reasons and had 1.3.1 and 1.1 MCU. Yesterday I decided to do it. I followed the instruction, installed ledger live and started the update process but during update several times different errors pop up, after each new error and search what to do with specific problem I managed to update MCU to version 1.5, BUT after that ledger got notification that MCU is not genuine and doesn't have identifiers and also I had to launch it in not secure mode. Booting option doesn't work, as it resets ledger to "MCU is not genuine" and I can't continue confirmation on Ledger live unless you agree (3 clicks) and in this mode ledger can't update and I have note "Ooops, try again, some connection failed". I read and tried everything what was written, changed computers, USB cabled, reinstalled all applications, restarted computers, and I did everything several times, nothing works. Seed restore also doesn't work, as "MCU is not genuine" resets connection to unsafe and everything repeats. Cry

It is like dead circle. I contacted ledger support, but nothing new from what I have already read or tried, they copy paste the same text I already tried. I sent them logs and screens and flow what and how happened but no reply.

As a bottom line I spent many hours on some bug which probably won't be fixed in the nearest future.

I have a few options what to do and want to ask for advice about that. I need solution only for ETH and ETH tokens, happy that I have never used it for other coins.

1) Mia offline Mnemonic Code Converter [/url]export all the keys and via MEW transfer tokens to other wallet (like this one https://iancoleman.io/bip39/)
2) Restore ledger seed on Trezor wallet. I found a few links that it is possible but not sure what problems I can face, if anyone knows what should be done or known in advance, I will appreciate if you share your experience.
3) Your option.

What would you recommend and why?

Just for reference, this is a matter of principle, I don't want to buy one more ledger just to restore the old one. The existing problem had happened due to some bug on their side which they can't solve and I have no wish to spend even $1 on them again.

Thank you all in advance.

This is a very bad situation, and I fully understand that you are disappointed with Ledger Nano S. Most of users have problems with firmware update, but with 1.4.1 version because of some driver problems and MCU update. I also check for this error on internet and there is many cases like yours - some are just give up and other managed to find a solution.

You did not write on what OS you are trying to make this update, but maybe you have problems with drivers ( I have problem on Windows 7) so check this thread, maybe there is something which can help you to solve problem. Also I see you try to make update on Ledger Live, maybe problem is in this - we all update firmware with Chrome App - Ledger Manager which is still work these days - maybe it's worth trying.

I read that one user is fix error like yours by doing this :

I manage to go through this by doing the following steps:

Connect ledger nano s to computer.

Verify MCU genuine appears.

Push 2 buttons on top at same time, read the instructions to safe mode.

Open ledger manager, it gonna show up with message that new firmware is available.

Install new firmware and its done, things back to normal and im in with new firmware.

Hope this helps.

MCU firmware is not genuine after the MCU update

It is good that you have only ETH on your device, so you can use few option to get back your coins, all info you need is in this link : Export your accounts
