Users who have not completed EOS mapping now can recover the EOS account. Please select import "Ethereum private key" when you are importing "EOS Wallet". It can help you fallback the original ERC20 EOS token to the EOS main network. However, the Ethereum wallet address needs to satisfy the following conditions:
1. You failed to register
2. You registered a malformed key
3. You had an outgoing transaction from your ethereum address within the block range of the snapshot.
4. Your address is not a contract.
If you're eligible for fallback registration, use this tool to generate your EOS private key.
