My latest version v0.3 (heavily modified version of the original as found in Post #1)
Made changes to correct major errors from my previous version, to put more fault checks in place and provide better instructions for non Nexus 5 devices to use. Version number is in the Window Title from v0.3. The process only takes ~2 minutes as opposed to the original script which takes ~15 - 20 minutes.
NABENDU1 you can use whatever your want from the script as you are the original developer of it and this is my contribution to what you have started.
