Ok, there's a new test version of this so we can proceed step by step.
It's at the same URL as before. If you're in doubt, the new version has MD5 of:
6b6405084318556f9bf39e3462d4332d
Flash it to recovery using EDL or fastboot or dd. Go to recovery.
Code:
C:\>adb shell
# start ttyscreen
-- it will type something to the terminal --
^C
# reboot
