I’ve been trying to wipe my iwork 10 (USB-C version) in order to sell it. I managed to wipe android quite easily but Windows is being difficult. When I do it through the settings menu (You can factory reset there) it fails at around 40%. It gives off no error code but just says it failed and nothing is removed. I tried it through reinstalling windows through a windows ISO file but the setup never starts.
Any ideas how I can wipe this tablet?
