How do I change from BSC to ETH on MetaMask?

To switch from Binance Smart Chain to Ethereum mainnet:

MetaMask is one of the best crypto wallets out there and easy to use. Supported by many BSC applications . You can use it as a browser extension or mobile app.

Send your ETH/ERC20 back to Binance from your Ledger BSC account. Send a small amount of BNB coins to your Ledger BSC account via the BSC network, the BNB will be used to pay for the transaction to send your ETH/ERC20 back to Binance.
