I've been enjoying this build for a bit, but decided to try some different launchers. Yesterday I downloaded Go Launcher and ADW Launcher EX from the Market, and tried them each once (I just clicked "open" after the Market installed them.) When I was done trying them out, I tapped the home button, expecting to choose which app I wanted to use as the launcher (and return to the stock HC one.) Instead, the screen dimmed and nothing came up.
I rebooted, and the when I unlocked the tablet, I got a blank screen + task bar at the bottom. From the task bar, I was able to get into Settings --> Apps, and from there I uninstalled Go Launcher & ADW, tried the home button, and still just a blank screen. Another reboot, same story. In Apps, I can see both Launcher and HTC Sense, and was going to "Clear Defaults" on them so I could select either one, but "Clear Defaults" as well as "Clear Cache" and "Clear Data" for both Sense and Launcher are grayed out.
I'm pretty stuck now. Any suggestions? And if a flash is suggested, can I do that without losing all my config settings (like Wifi)?
