@Luke1931 Plugging into a powered on computer is the only way I can get my Tab A7 to go into recovery mode. It's a bit of a faff and people without one are screwed. I tried headphones and also the power adaptor but only the PC method works. Anyway the keys to hold down when it is turned off and plugged into a PC are Power and VOL UP together until the logo appears. Do not hold them any longer or the tablet will turn off again. In recovery mode she can factory reset without entering Samsung Account Details
