Need Help to get wordpress website back (tabel prefix problem)

Hi,

when i am trying to access wordpress login page it’s redirecting me to wp-admin/install.php page and website also shows white death screen and the problem is we also don’t have backup and reached to hosting provider they also dosen’t have. i tried all the ways means all plugins and themes deactivate. also wp-config.php file checked there is all information are correct but table prefix missing so i tried default table_prefix

$table_prefix = ‘wp_’; but can’t works and in table list there is no table starting with wp_ .
all tables are starting from:-
1) advertisement_
2) default_setup
3) listing_
4) seller_
5) setup_
6) tmp_
7) visitor_ etc but not with wp_

so there is any way or solution to get website back?

I hope we find solution

thanks
