I’ve been working through Christian’s marvelously clear explanation for installing ICS on my TP (http://www.makeuseof.com/tag/install-android-ice-cream-sandwich-hp-touchpad-minutes/) and have run into the same problem as some others: when I’ve gotten to the command-line work, I get the “unable to find device” message. The USB icon is definitely on my TP screen, and I’ve tried the fixes suggested in the Comments, like a new USB cable, disconnecting my hubs, etc. No good. I’m broken-hearted; I have ICS on my new Galaxy S3, and I would love to make my TP versatile again by doing the same there. Have you any suggestions? Would it make sense to *not* Eject the TP before trying, even though the instructions say to do that? When I Eject, the TP no longer appears as a drive, so I can see why my PC can’t see it. I’d be very grateful for your help, and thanks in advance.
