I recently unrooted my OG droid and flashed the stock SBF. I was able to install apps saved to my SD card and some from the market. Now 2 days ago I can't install any apps. This includes the market and amazon. They get downloaded, but hang upon install. I can't clear market cache as it only shows computing and never shows how much data/cache there is. Rebooted phone several times and I'm still not able to install apps. Anyone have any suggestions?
