I added your success report to the "success reports" list. Using a custom runme.sh script is the OLD way of debricking, before we started recommending simple debricking by simply flashing uncorrupted firmware images.
It is great to have the "old debricking method" working here, but I think we still need to find out how to get USB Downloader mode working. Or at least, we need a way to make using runme.sh more noob-friendly. Thanks guys!
