I'm getting the replacement screen/digitizer from a reputable US dealer on EBAY. I have watched two videos on YouTube that aren't directly related - one, disassembling the entire Maven but not specifically screen replacement. two, screen replacement of a ZTE phone, but not the Maven.
You can find these by doing a search in YouTube.
When I disassemble my phone within the week and replace the screen/digitizer, I will post it.
