As I said on social media today, it’s 2019 and I’m updating the Firmware on a Zune, fight me. 😉 There’s even an article on Vice about the Zune diehards. The Zune is a deeply under-respected piece of history and its UI marked the start of Microsoft’s fluent design.
Seriously, though, I got this Zune and it’s going to be used by my 11 year old because I don’t want him to have a phone yet. He’s got a little cheap no-name brand MP3 player and he’s filled it up and basically outgrown it. I could get him an iPod Touch or something but he digs retro things (GBC, GBA, etc) so my buddy gave me a Zune in the box. Hasn’t been touched…but it has a super old non-metro UI firmware.
Can a Zune be updated in 2019? Surely it can. Isn’t Zune dead? I hooked up a 3D0 to my 4k flatscreen last week, so it’s dead when I say it’s dead.
IMPORTANT UPDATE: After I spent time doing this out I found out on Twitter that there’s a small but active Zune community on Reddit! Props for them to doing this in several ways as well. The simplest way to update today is to point resources.zune.net to zuneupdate.com’s IP address in your hosts file. The way I did it does use the files directly from Microsoft and gives you full control, but it’s overly complex for regular folks for as long as the zuneupdate.com server exists as a mirror. Use the method that works easier for you and that you trust and understand!
- First, GET ZUNE: the Zune Software version 4.8 is up at the Microsoft Download Center and it installs just fun on Windows 10. I’ve also made a copy in my Dropbox if this ever disappears. You should too!
- Second, GET FIRMWARE: the Zune Firmware is still on the Microsoft sites as well. This is an x86 MSI so don’t bother trying to install it, we’re going to open it up like an archive instead. Save this file forever.
Third, FAKE THE ZUNE UPDATE SERVER: Since the Zune servers are gone, you need to pretend to be the old Zune Server. The Zune Software will “phone home” to Microsoft at resources.zune.net (which is gone) to look for firmware. Since the Zune software was made in a simpler time (a decade ago) it doesn’t use SSL or do any checking for the cert to confirm the identity of the Zune server. This would be sad in 2019, but it’s super useful to us when bringing this old hardware back to life. Again, there’s as half dozen ways to do this. Feel feel to do whatever makes you happy as an HTTP GET is an HTTP GET, isn’t it?
NERDS: If you use Fiddler or any HTTP sniffer you can launch the Zune software and see it phone home for resources.zune.net/firmware/v4_5/zuneprod.xml and get a 404. It if had found this, it’d look at your Zune model and then figure out which cab (cabinet) archive to get the firmware from. We can easily spoof this HTTP GET.
NERDS^2: Why didn’t I use the Fiddler Autoresponder to record and replay the HTTP GETS? I tried. However, there’s a number of different files that the Zune software could request and I only have the one Zune and I couldn’t figure out how to model it in Fiddler. If I could do this, we could just install Fidder and avoid editing the hosts file AND using a tiny web server.
From an admin command prompt, run notepad windowssystem32driversetchosts and add this line:
This says “if you ever want stuff from resources.zune.net, I’ll handle it myself.” Who is “myself?” It’s our computer! It’ll be a little web server you (or I) will run on our own, on localhost AKA 127.0.0.1.
Now download dot.net core, it’s small and fast to install programming environment. Don’t worry, we aren’t coding, we are just using the tools it includes. It won’t mess up your machine or install anything at startup.
Grab any 2.x .NET SDK from https://dot.net and install it from an MSI. Then go to a command prompt and run these commands. first we’ll run dotnet once to warm it up, then get the server and run it from our zunestuff folder. We’ll install a tiny static webserver called dotnet serve. See below:
dotnet tool install --global dotnet-serve
dotnet serve -p 80
If you get any errors that dotnet serve can’t be found, just close the command prompt and open it again to update your PATH. If you get errors that port 80 is open, be sure to stop IIS or Skype Desktop or anything that might be listening on port 80.
Now, remember where I said you’d extract all those cabs and files out of the Firmware MSI? BUT when we load the Zune software and watch network traffic, we see it’s asking for resources.zune.net/firmware/v4_5/zuneprod.xml. We need to answer (since Zune is gone, it’s on us now)
You’ll want to make folders like this: C:usersYOURNAMEdownloadszunestufffirmwarev4_5 copy/rename copy FirmwareUpdate.xml to zuneprod.xml and have it live in that directory. It’ll look like this:
The zuneprod.xml file has relative URls inside like this, one for each model of the Zune that maps from USB hardware id to cab file. Open zuneprod.xml in a text editor and add http://resources.zune.net/ before each of the firmware file cabinets. For example if you’re using notepad, your find and replace will look like this.
- UPDATE: As mentioned above, I did all this work (about an hour of traffic sniffing) and spoofed the server locally then found out that someone made http://zuneupdate.com as an online static spoof! It also doesn’t use HTTPS, and if you’d like, you can skip the local spoof and point your your windowssystem32driversetchosts with an entry pointing resources.zune.net to its IP address – which at the time of this writing was 220.127.116.11. Your hosts file would look like this, in that case. If this useful resource ever goes away, use the localhost hack above.
- Now run the Zune software, connect your Zune. Notice here that I know it’s working because I launch the Zune app and go to Settings | Device then Update and I can see dotnet serve in my other window serving the zuneprod.xml in response.
It’s worth pointing out that the original Zune server was somewhat smart and would only return firmware if we NEEDED a firmware update. Since we are faking it, we always return the same response. You may be prompted to install new firmware if you manually ask for an update. But you only need to get on the latest (3.30 for my brown Zune 30) and then you’re good…forever.
