Correctly hashes against

MD5SUM = 8e42ffe324a9109031dd4f9dd53fdc9a

SHA1SUM = 49789b240cab9a8e91c1f5a3eb0b6be0b07b5732

For the 4.4.2 (KOT49H) Image (NOTE: The original flash that I showed the output for was for the later image 4.4.2_r2 (Verizon) (KVT49L)) In the past I have had more success with the KOT49H image and will continue testing using this image.

Here is the latest attempt at flashing using the flash-all.sh script

I agree that these write speeds seem a little too quick

Sidenote: Before I tried this last flash I was able to confirm that the digitizer is functional. The devices appeared to boot into the factory image (screen was still black) I was some how able to get the accessibility options enabled so that the devices would speak out my actions. I did not complete this tutorial. This leads me to believe there is some more bizarre underlying screen issue. Possibly a loose cable?
