Trezor1 updated/how to reset wallet

i read the post that after an update you might not see your coins -
how do I restore the wallet? The wallet without the coins is still on the trezorsuite.
(i ensured I have the right seed phrases & passcode)

the instructions on the earlier post I read seems to be for a new trezor.

many thanks

ignore the above question - i had a different passcode - i got in thanks
