Glad you got it back to working again. I've been relying on the app on my iPhone because the only PC I have is an 11 year old laptop that runs Vista. Unfortunately, the version of etube that supports 8050 won't run on Vista. Everything I read says the app is wonky and definitely don't use it to upgrade firmware. I've been thinking about picking up a cheap laptop to use for etube and your issues have pushed me to do go ahead and order it.
