yesterday I've recieved my Chromecast with 38xxxxxxxxxxx serial, which I've bought in the US. I've rooted it and everything went well. But I wasn't aware, that I would need the Flashcast USB drive afterwards to flash additional addons. So I've used my 64 GB main thumb drive for rooting my Chromecast. Is there a easy and fast possibility to create another Flashcast USB drive without re-rooting my chromecast? I have alot of smaller drives, which I would have used, if I'd have known, that I would continue to need the USB drive after rooting my chromecast.
