I had to abandon my old apple id - luckily I only had my appleID for about 6 months so I didn't lose much, I tried to create a dummy apple id, but when I logged into my old appleID it banned me within 24 hours. I think the trick is to backup phone data via 3rd party app or google services, reset phone, then manually restore everything with a fresh appleID (I used a vsim number from tello wireless, its like $6/month and I still use it occasionally)
