I recently flashed sbf so I could do the new OTA update, but lost root. I have Z4 on my SD card, but can't figure out how to install it. I have a couple of app installers, but they don't seem to see anything on my SD card. I know it's there, along with a bunch of other stuff, because I have Astro and when I open it it's right there. How can I install it, can I do it with Astro? Any suggestions would be greatly appreciated.
