Same thing happened to me last night. I was ib too much of a hurry and one of the adhesive tabs broke off. I thought, being the smart ass that I am, that the battery wouldn't need heating and i could just lever it out. Well I urge you all to follow the above proceedures very, very closly !!

Goodbye iPhone 6+ and I havnt backed it up for two months, thats another thing you should all be religious about. World of Pain here I come
