I have a new RK 2918 tablet from Yuandao - the N90. I am having a couple of problems. It has some Chinese games that I can't figure out how to delete them. I stumbled upon a list of the files but when I selected delete, it wouldn't allow me to delete. Is there any way short of reflashing my chip to get rid of things? When I try to download an app, it comes up saying "China Mobile Unknown N90" and "can't download app for your country". Any help would be greatly appreciated. I am very experienced on PC's but new to Android.
