Ive been trying for months because downloading the beta was a mistake i admit. I have tried to downgrade to 8 but ive been getting an error. Its been a nightmare. And now the past few days everytime i unlock my iphone and ipad mini it tells ios9 is available and to upgrade but ive not been able to. Its been so frustrating. I cant take it to the genius bar because the next appointment isnt till Friday. The glitch after unlocking has me pulling my hair out. Should i just walk in? Would they take me? Help!
