So I bought some crypto some years ago, and have used a Nano Ledger S to "protect" them. Now I see the Ledger needs upgrading (current MCU 1.1 and firmware 1.3.1). I have my recovery phrase written down. Are there any things I need to avoid doing when upgrading the Ledger?
I find the instructions on ledger.com confusing. I have tried to use the Ledger Live software without success.
Should I buy a new Nano Ledger, or try to upgrade the old?
