ok, I cracked the screen of this N800 a WHILE ago when I fell and it was in my pocket. After that, I somehow bricked the replacement unit I bought. Since the screen was fine on that one and the cracked one was still functional (minus the black sections from the crack) I decided to use a tutorial I found online to disassemble both units and put the working screen on the working unit (and the cracked screen on the bricked unit)... after reassembling, it refuses to power on. If I hit the power button (or plug it in) the NOKIA screen pops on for 1 second, then goes completely off... it repeats this maybe 3 or 4 times, then stays off... is this a lost cause, or can I fix this issue? It won't even let me reflash... the "power blink" happens no matter what I do, battery, cable, or plugged in by usb...
