This is different from any other thread, because my Nexus 7 ... IS rooted, has been found and opened with the PC for 9 months or so. The problem, is that I had a hard-drive failure. The C Drive died and so good old WinXP needed to be reinsatlled on a new 360 GB hard-drive. That's all been set up. I was able to get the drivers to my rooted phone, pulled off the phone, so the phone, it's sdcard and all are accesable by PC, that part's good now. I've been trying Wuggs, Nexus Root Tool, (repeatedly) and the ADB drivers, are installed, and show as Nexus 7, in device manager, ... than the fun start's. Of course settings/developer options/debugging is turned on. This tablet, isn't being opened or found as a usb device and given a drive letter, at all. (accept in device manager) so ...? Deleted the drivers and reinstalled them, the tool kit, can't confirm they are installed all the way or correctly. I have tried other USB port's, shortened the cord, minimal running programs on the PC tried the other drivers PdaNet, etc. I've booted into recovery with the USB cord plugged in, (with device manager on my screen) so I could see any changes, it seems to correctly identify the found tablet and act's as if it's all set up. Nothing's working though. I want a "connect to PC" window, and the choice to connect as MTP (media device), or install driver given, but that's not possible when the USB cable is plugged in. What should I do? What have I forgotten, (or never learned) about these driver installations? Thanks.
