Every time I try to install a .zip file I get this error: "finding update package" "opening update package" That will pop up and quickly disappear then take me back to the main menu. This happened's to all the .zip files that I tried installing. (tried both named update.zip and the name it came with when I downloaded it on the computer). I tried this by using ROM manger, and holding X and the power button. I've tried using Clock mod and SPRrecovery and nothing still. People have been saying that the file is corrupt. I've tried different files and still get that error. Anyway to fix this?
