Hello aspirant,
Yes, you have to register again with a new phone number and mail id while making a new but another registration. No doubt you once registered and then opted the reset option, still in the site of the respective deemed university, the officials keep a record of the email ids and contact number if once you have registered and if you reset. Simpler terms, they keep a unique record. You can't be able to use that again. So for that, you have to use another phone number and email id so as to make a new registration.
Hope, it helps you.
