My device showed that the update downloaded and I waited 24 hours before actually running the update. I started the update and walked away from the phone. I wish I would've watched it run the update because it doesn't look like it installed. My device shows that I am still on 5.1.1 and on the System Update screen, under Last System Update, it says "Software not updated to 23.31.24.en.US Download failed. However, when I run "Check for System Updates" it says "Your device's software is up to date".
Something obviously went wrong with either my download or the installation. Can anyone say where on the device the download file is located? I thought if I could remove the 'bad' download, perhaps my phone would recognize there is an update available. Any suggestions?
