I tried updating to 7-18 firmware update (mine came as 7-5). I downloaded the file from PD site to my SD card. However, when I tried to install, the machine first freezes. I had to hard reset twice to get it out of the booting loop. Finally when the installation bar appeared, I thought I was succeeding. But the orange bar only got barely 1/2" long when the PDN rebooted itself. At first I thought it's a faulty firmware and tried downloading another one from this forum. But same thing happened. My question is: Is this orange installation bar supposed to go all the way to the end before the booting begin? Do I have a faulty machine on hand?
