I know this is an old post, but today I replaced my Dell Venue8 touchscreen and the horizontal axis was reversed. I found this post, but the reflash batch files didnt work.
I however found another post here: http://mydspclub.com/forum.php?mod=viewthread&tid=465

My original screen was the JWXFW and the replacement I got was the Y3J89. After running the TPK version above, it updated the FW and my tablet is now as good as new!
