Hi I bought a demo dxg on ebay and on developers menu I chose M update on mmc and put the password from the sir alex tool.Now it stays on the guy with the tree screen.I can get to the development menu and the reset screen,the progression bar shows but nothing happens comes back the screen with the tree.I got a serial adapter as described here and I tried Hyperterminal but I see nothing.I tried with 3.3 5v nothing,Tried to modify the adapter to output 1.8v ,but still I see nothing.I jumped Tx Rx i see nothing in the Hyperterminal.Maby I fried the kindle ? or the addapter is no good.Please help!!Thanks
