So I recently rooted my NC 1.2 with manual nooter. Everything seems to be fine but I am trying to install the amazon appstore and I am having some trouble. I download the apk to my sd card, but I cannot copy it to /system/apps. I have astro file manager, and E S File Explorer installed. I think the problem may be that I don't yet have write access for /system/apps but the option to mess with that in E S File explorer is greyed out. Anyone have any suggestions? Thanks.
