Ethereum sent to Ether Classic Wallet

Hi, Ive read how to access my Trezor Wallet via MEW to solve my mistake but the Trezor version I’m running (1.11.2) will not allow access. As I understand it, I need to downgrade the firmware to a prior version, but what version should that be and where can I find that version? Thanks Eric

you don’t need to downgrade the firmware. What is exactly is your is issue with accessing MEW?
