Is there a way I can transfer the bitcoin to Electrum despite it being an older firmware update? I tried setting up the wallet a few times but the BTC balance never shows up. Thank you to anyone who can help.
I don't think having an old firmware should affect your balance.
Did you try connecting the wallet directly through Electrum itself?

Use a hardware wallet.Do you recognize the addresses? Do you your transaction history (and any outgoing transaction etc...)?
