(a)I have a q, what are the steps should be taken to restore the DB.
as i have to recover/restore the DB using the new ctl(restore ctl file)

(b) I found out that to restore ctl file the Db should be mounted. What if i lost the ctl file, I cannot restore the ctl file?. during my back procedure i do the following
backup
current controlfile
tag = my_cf
format '/backup/prod/backup/full/ctl/cf_%d_%t_%u.f';

(C) CAN YOU EXPLAIN WHAT I DID WRONG IN THE ABOVE STEPS 1-7
Thx
In adv

ther is no restoring a database in there - is that intentional?

you restored an old controlfile and did nothing else, so it was out of sync with all the datafiles

why did you do that?
