Hello!

Everyone's heard about the Ledger Recover.

There are last versions of Firmware/Software BEFORE Ledger Live was implemented:

Ledger Nano X
OS version 2.1.0
Released 14 February 2023

Ledger Nano S Plus
Firmware version 1.1.0
Released 14 February 2023

Ledger Live 2.53.1
Released on February 8th, 2023

Who has an experience of building Ledger Live from the source code. Have you tried to change update links to make an update before Ledger Live was released?

For now I found in source code a request through the Websocket for the firmware update.
wss://scriptrunner.api.live.ledger.com/update/install?firmware=nanos%2B%2F1.1.1%2Ffw_1.0.2%2Fupgrade_osu_1.1.1&perso=perso_11&firmwareKey=nanos%2B%2F1.1.1%2Ffw_1.0.2%2Fupgrade_osu_1.1.1_key&livecommonversion=33.5.0

Here is the path where the firmware update piece of code is located: ledger-live-develop\libs\ledger-live-common\src\deviceSDK\commands\firmwareUpdate
Github page for Ledger Live to build: https://github.com/LedgerHQ/ledger-live

[Piece of code]
BASE_SOCKET_URL: {
    def: "wss://scriptrunner.api.live.ledger.com/update",
    parser: stringParser,
    desc: "Ledger script runner API",
  },

For Apps installation Ledger Live uses this domain: scriptrunner.api.live.aws.prd.ldg-tech.com.

Are here anyone who already done the research and have successfully downgraded / made previous update of ledger firmware?
I would happy to receive any tech information that you can share here. Wait for further comments.
