I used the 215 originally. My phone won't stay on long enough for my to try the 219. I know there has got to be some way to power it while doing this though. I also couldn't find a USB hub locally so I spliced two cables together, power coming from wall wart, data going to PC. Still no luck for some reason. Also, from what I understand, 17/18 was webtop. That's also the error it gives me on the phone for the reason it isn't booting.
