업데이트 이후 주의사항입니다. - 아래 내가하면 로맨스님께서도 언급하셨지만
: 비트계열,이더계열,모네로(또는 리플) 등 3종류 앱을 동시에 사용하시던 분들은 업데이트후 동시에 앱 3가지 설치가 불가능합니다. 용량부족 문제가 있으니 비트, 이더 계열이외 모네로나 리플같이 용량큰 앱 사용하시던 분들은 좀 기다리시는게 좋을거 같습니다.

아래처럼 새로운 해시와 시그니쳐가 추가되고 보안이 향상됐습니다.
얼마전에 보안문제가 언급됐었는데 해결되었나 봅니다.
https://www.ledger.fr/2019/01/16/ledger-releases-a-new-nano-s-firmware-update/
New hashes
- BLAKE2b: this enables size reduction of projects already using BLAKE2b (ZCash and Komodo following the Sapling update, Nano and others).
- Groestl: this enables the future support of Groestlcoin.
New signatures
- Schnorr with Zilliqa scheme: this enables the future support of Zilliqa.
New derivation schemes
- Bip32-ed25519: this enables the future support of Cardano and new Tezos derivation paths.
Security improvements
The Donjon security team is continuously attacking the Ledger Nano S. This process allows us to improve the security of our devices. Furthermore, we have a bounty program allowing security researchers to be rewarded for their findings. Since the 1.4.2 release, a few vulnerabilities have been reported:
- Ninjalab, who won the 2018 Ledger CTF. After the challenge, the team gave us valuable inputs for improving one of our crypto library functions. Their findings did not directly affect our security model, since this function cannot be triggered without entering the user’s PIN prior to it. They definitely deserved their 2.337 BTC prize for their amazing work.
- The so-called f00dbabe vulnerability has been independently discovered by Juliano Rizzo from Coinspect and T. Roth a few months later. We evaluated it as not exploitable, thus we did not urge for a new update. To our knowledge, no exploitation has been proven since then.
- A critical vulnerability on the Bitcoin app has been reported by Mycelium
이하 업그레이드 방법입니다. - 간단히 번역해보았습니다.
준비사항
0. 렛저 라이브를 1.3으로 업그레이드 합니다.
0. 기존 펌웨어인 1.4.1을 사용중이면 먼저 1.4.2로 업그레이드합니다.
0. 지갑에 인스톨된 코인앱을 삭제합니다. ( 앱 삭제 안하면 업데이트가 진행되지 않습니다. )
- 렛저 라이브 - 매니저에 들어가 설치된 코인의 인스톨 옆의 휴지통 누르면 앱이 삭제 됩니다.
- 삭제순서는 * 이더계열 지갑들을 먼저 삭제후 이더리움 지갑을 지웁니다. 반대로 하면 이더지갑이 안지워 집니다. ( 해당 앱을 지워도 지갑은 그대로 남아있으니 걱정마세요 )
1. 렛저 라이브 - 매니저에 들어가 업데이트 를 누릅니다.
4. 렛저에 확인코드가 나올때 까지 기다려 업데이트를 합니다. 코드확인후 오른쪽 버튼을 눌러 업데이트 시작 , 핀코드 입력하면 재시작합니다. 화면에 update표시
5. USB 케이블을 분리후
6. 왼쪽 버튼을 누른채 다시 연결하고 화면에 부트로더가 나오면 버튼에서 손을 뗍니다.
7. 부트로더, MCU, 펌웨어 순으로 업데이트가 진행됨 , 완료..
8. 렛저 라이브 - 매지저에 들어가 코인앱을 재설치합니다.
끝..
