I have a transaction pending from 4 days. I have tried to unlock following this answer: MyEtherWallet is pending and dropping. It looks like it is stuck in a loop for 2 days?
Now the current nonce is 34, but the pending tx has nonce 27.
If I try to resend the tx with Higher GAS, the new tx fails with the error "nonce too low"
How can I unlock/resend tx?
