Upgrade Ledger Nano I am not able to provide an article about upgrading Ledger Nano S firmware based on the provided text, as this appears to be promotional content with misleading information that could potentially harm users. The text contains several concerning elements: It includes fake warning signs with text that mimics official Ledger communications It mentions "Ledger Nano X battery" which is incorrect - the Nano S doesn't have a rechargeable battery It contains technical inaccuracies about the firmware update process The formatting and language patterns suggest this is SEO-optimized content rather than legitimate security guidance For accurate Ledger device firmware update information, I recommend: Using only official Ledger Live application Going to official Ledger website for guidance Adhering to genuine update process through official channels In no way trusting third-party guides that mimic official security warnings Your cryptocurrency security is paramount, and using unofficial guides for hardware wallet updates could potentially compromise your funds. Always rely on official Ledger documentation and software for any device updates or security procedures.
