I was trying to update one of my units and in the middle of updating applications, (Connecting for the first time), it decided to shut off. Now it doesn't matter if I switch the battery or SIM card, the thing still doesn't power on. All that happens is that once the battery is placed back inside the device it starts blinking red. It blinks twice, pause, two blinks, pause, etc. Any solutions. I can't power it up to reload the OS or anything. Thanks
