Database Corrupt: error 823

Hello there
After i tried to run DBCC CheckDb and it gave error, i has made to detach
the database.
When i tried to attach i got error 823: error (Bad page id).
What i can do now to fix the MDF file?You would want to restore from a backup. If you do not have a backup, the
following might help you recover what left of your data. Any doubt, contact
MS support.
1. make a backup of your *.mdf, *.ldf
2. set the db in emergency mode
exec sp_configure 'update','1'
reconfigure with override
go
update sysdatabases
set status=32768
where name='your_db'
go
--stop sqlserver
shutdown
--now restart sqlserver
go
3. rebuild log
dbcc rebuild_log('your_db','<fullpath_log_filename>')
go
4. attempt to fix with loss of data
exec sp_dboption 'your_db', 'single user', 'true'
dbcc checkdb('your_db',repair_allow_data_loss
)
go
5. reset db status
update sysdatabases
set status=0
where name='your_db'
go
6. turn off update
exec sp_configure 'update','0'
reconfigure with override
go
7. restart sqlserver
