I had a K1 and dropped it and cracked the screen. It ran OK but the screen looked horrible. I bought a used one which just decided not to work anymore (except to show the Lenovo flash). I decided to replace the guts of the first into the frame of the second. I followed the manual in taking them apart. BUt when I put the working frame and working guts together,it cranks up and wants me to swipe my finger, but the touch screen will not respond. Any ideas on what I did wrong? THanks.
