Funny to see "abill_uk" thanked this post..! The person is in a problem so it would be better to help him out rather than giving a "thanks: ...however, coming to the problem - I too faced a similar problem like this, I charged the gadget using external charger for nearly 1-1.30 hours. It repeats the on-off sequence but dont care about it...it will charge. But to bring it to life again I did 'reflash'. Might be this would be your last option if other solutions dont work out.. All the Best. Do let me know
