In my database 2 redolog files. but both are corrupted. so i cannot start the database. If i create these 2 redo, it also cannot start the DB. My DB is in noarchivelog mode. Help me how i can start?

without being in archivelog mode you are out of luck. restore your last cold backup. Since no one would run a production database without archivelog then it must be a test database and you can rebuild the database from scratch.

If you have export dump file, you might reinstall your database and import your schema back to your new database.
In that case you can recover your database till when you backup your export file.
