Hi mio, I have a problem with my DR500gw, one day it just started speaking a different language, I flashed a different firmware to it and it did not boot completely, I formatted it thru the pittasoft gui and the symptom came back. Any help will be appreciated. I posted a link in youtube for your reference. waiting for your reply. https://www.youtube.com/watch?v=lx9ZUTdD4h4
