Now, before you continue I highly recommend syncing the account thats there with your phone, or at least making sure the sync is up-to-date. When I did this next part, all the contacts and settings and stuff on my phone got erased. They DID come back later when I re-synced the original account with my phone, so no worries (also my friend’s contacts/settings didn’t disappear at all so idk whats up with that
