Yes, I have tried three different wall chargers (All worked prior to update). Tried two separate USB chargers into my computer... Also tried to plug the USB cords into a wall adapter. I don't have an external Charger to test it unfortunately....
do you happen to have another battery. my standard battery died exactly one week after the warranty ran out. it just quit charging. it might have been that the same thing happened to you at just the wrong time and may all be a coincendence.
