It’s not entirely clear from your post what state your device is currently in. How did you reset your Trezor device - did you do a Factory reset?
Anyway, if you set it up from the start then you choose Recover an existing wallet instead of Create a new wallet (see image below), then input your existing Recovery seed (backup). You also need your Passphrase at hand to be able to access any Hidden wallet.
If you recover your exisiting wallet then you don’t make a new backup. You only make a backup when you create a new wallet and thereby creating a new batch of 12 words as your Recovery seed.
A newly created wallet is always empty. If you had any funds in your previous wallet (with the other Recovery seed) then they are not recovered when you created a new wallet and you must do a recovery of that wallet if you want the funds back.
Yes, but you checked the recovery of your new wallet. The old wallet your had before the Factory reset is connected to your other, previous, Recovery seed (backup).
Please don’t proceed with storing any funds in your Trezor until you fully understand this, and other basics, or else I fear you’ll quickly find yourself in a situation where you’ve lost funds and aren’t able to recover them.
What should I do? How do start over completely new? I want to reset it completely and do a new backup, should I use a different computer because the one I’m using has a backup on it?
Can I start fresh, in the initial set up, i put a wrong passphrase on the screen ( the screen was too small and it didnt ask for confirmation so I didn’t know what passports it was
Second time, I did a new setup but it didn’t ask for a backup which got me worried
Third time now, I wiped the data of the device and uninstaller ttrzor suite, so hopefully I can do the whole sequence again, including a new backup
