The recovery steps you tried look correct to me. Do you have all of the archived redo logs from the time of the last backup until the time of the error? If so, the recovery should succeed.
I am surprised though that the recovery wants to start with the very first archived redo log. Was the database in archivelog mode at the time of the problem? Or did someone change it to archivelog mode later? Or, maybe the “ALTER DATABASE OPEN RESETLOGS” succeeded, at least in terms of resetting the archive sequence number to zero, but without restoring the data you need.
From now on, please do regular exports as well as backups. From an export, it is much easier to recover an individual table than it is from a backup.
Another option for you may be to create a new Oracle instance, then use it to open the backed up data files and export the table you need, then shut that down, open your main database and import that table.
