I've just sent to my Ledger ETH Wallet some ERC20 Token,
But the wallet is not ERC20 Friendly
How can I send them to my MEW?
I'm not an ETH expert. However, have you tried exporting the wallet file or the unencrypted private keys and importing those into myetherwallet? Since myetherwallet is ERC20 supported and connects to remote nodes, you should be able to access your ERC20 balance.
If this doesn't work then i'm really sorry but i haven't had enough experience to help you. But i have and am using myetherwallet to store ICO tokens right now so i have experience and can vouch that it works.
