Kookoo: After 4 great years my Acer Iconia A501 has finally decided it has had enough. The poor Android is lying down with the red triangle, and I can't boot into recovery mode or boot it from sd card using an update.zip. So, it's time for us to part ways, BUT. I am pretty sure that I unless it's a hardware fault, it can be resurrected. So how do I ensure that if someone manages to resurrect this tablet, they can't access the information stored on it?
Job done. (Be aware of exploding Lithium battery potential)
