I'm getting an error when I try and ugprade my Android version. I'll start with the history and spec first:
Google Nexus One, bought in April 2010, it had Eclair (2.1) on it. I wanted Froyo 2.2 (for the hotspot/tethering) but the update delays being what they were I ended up rooting it, getting clockworkmod, and installing CyanogenMod 6 (based on 2.2). It's been the same ever since and I've been happy with it. It's only because a month or two ago it stopped being able to update any of the apps that I'm even wanting to upgrade, otherwise I'd be happy with CM6. I can no longer update or even search for apps. If I can't go back to plain Android because I've gone CyanogenMod, that's fine, I'll just go for a newer version of it.
I'm not wanting to live on the bleeding edge with ICS4 on this old-timer (yes I've heard it runs but with bugs), so if I can, I'll go for a plain vanilla Gingerbread 2.3.3.
I downloaded 2.3.3 from and renamed it update.zip and put it in the root of my SD card. I shut the phone down and then followed the instructions I found .
It seemed like it would be easy, but I'm getting this error after choosing "Apply sdcard: update.zip". After the error I show two screenshots of how I got to that point.
