    Re-download the update.zip in case the original was corrupt; no MD5 checksum is provided so compare file sizes. If there's any difference then you can assume that the original was defective. If not then the source file itself is probably defective.

    Wow, that's for Gingerbread (2.3)!

    Anyway, yeah, that update.zip file is not an "official" update.zip file that would (or could) have come from the manufacturer--i.e., it's not an officially signed file ("jarsigner.exe -verify update.zip" yields "jarsigner: java.lang.SecurityException: SHA1 digest error for META-INF/com/google/android/updater-script"--which indicates that the contents of the META-INF's folder (i.e., the file signature(s) does NOT match it's contents).

    This jibes with it's contents is basically a simple root package installer (su, Superuser.apk, busybox, etc.) which is normally installed by a custom recovery (which would have been ClockworkMod recovery for 2.3) and would typically not be installable by a stock recovery as the web site instructions--unless you've got a (very rare) device that somehow does not check the signature of an update.zip file.

    For the record, here's the update.zip file's MD5 and SHA1 sums to compare with what you might have downloaded:

    c:\Users\Scary Alien\Downloads>md5sum update.zip
    eac189609fd71de6bf053e7ff2636d7e *update.zip

    c:\Users\Scary Alien\Downloads>sha1sum update.zip
    89108755e3cf1d6c298e60fc963881dacb3d313d *update.zip​
