Samsung MM-A920 - Software Upgrade

So I reset my phone just now for the first time in a long time.  When it booted up, it said:

Information: A new software version is available for your phone.  Would you like to continue?  (Yes/No)

Would I like to continue booting my phone? Or would I like to download the software? I'm not sure which, actually. Well, pressing yes then prompts with:

Warning: Once the update has started, it will proceed until completed. You will not be able to use your phone during this process, even for emergency calls. The process will take 10 minutes to complete. (Next/Cancel)

OK, why not? Let's do it!

Next leads to:

Information: Please select from the 3 options below?
1. More Details
2. Update Phone SW
3. Cancel
(Yes)

The UI is starting to look silly. Of course, I had to go with #1 first. That gives this:

Description: Priority: High
Part 1 of 2 software update. Please proceed to Update Phone Software again after this part is complete (OK)

Yes, it was missing the period. This is good, though. That means I get to do this twice. Pressing #2 gives a progress bar and a "please wait". Then it goes into what looks like text mode and shows another progress bar with an "initializing" and a % complete.
Then it switched to, "Your phone is being optimized, please wait..." and another progress bar. This part is taking longer.

After resetting it says:

Information: Update Complete! (OK)

Then it goes in to a "reporting status" progress bar and then, finally, we're back in to the phone. No notice or reminder that there is another half of this upgrade to go...
