I have one that hasn't been used in a long time and it has old firmware (1.2) I have no idea how to update it and have contacted Ledger support, but have not received a response. The website says to use Ledger Live, but that it cannot update firmware older than 1.3 and below. It also says to contact support about a replacement device. I'd rather find a way to update it - if anybody can help, I would appreciate it so much. Thanks in advance for those who provide answers.
