[revolver183]

C-4.

[J03Z]

um whats C-4?:S lol. and yeah id also like 2 know if anyone knows how to get unicode support on d zune without opening it.. well im indian and only speak english.. lol. but still it would be cool to iF**** off all those pod supporters and zune haters by boasting a zune LOL.

UPDATE:
Yes, you *can* trick the update software to update the font files for you. No need to open the case and do the hard drive swap.
I used the same process used to 'downgrade' to older versions of the firmware, but added the .TTC files as well. There are many different methods (found months ago).
----
AFAIK: nobody has released a public tool to downgrade the firmware (AFAIK I was the first to do it, and since then a few people bragged about it, and several people started working on a replacement version to get around the ZUNE.EXE dependence).

Anybody have a tool (nearly) ready for public release ?
If not I'll probably polish up my version and release it to the unwashed masses.
----
IMHO this is only a marginally interesting hack. The real pay-dirt is if we can use the technique to find an exploit to make homebrew a reality.

I'm confused. Does this mean that the users will be able to do the Non-US character hack without getting access to the system partition?

[ZunePet]

Sorry for not being clear. I am trying to address 3 different audiences.
I repeated my earlier 'dingbats' experiment with a sealed Zune. Software only. Exact same results (boxes before, dingbats font after).
The only remaining work is to produce a firmware update tool that is easy to use for newbies, and a tutorial.
----
To general Zune owners:
Yes, soon you will be able to display UNICODE song names on your Zune (Chinese, Korean, Japanese, dingbats). Custom fonts should also be possible.
No hardware modifications needed. No expensive ZIF adapters. No need to remove the Zune case.
Someone will provide a simple and free program that you will run on your Windows machine. It will copy over the font files for you (software only).
Keep checking the boards.

-----
To more technical audience:
The update software (part of ZUNE.EXE) will copy the font files to the system partition for you. This is not a general purpose access to the system partition. It is used to update the 3 BIN files as well as special files like TTF (true type fonts) and TTC (true type font collections). See the 'mtpusbfn' module in the firmware for more details.
So far we can only use the 4 special .TTC font collections since they are hard coded in the registry.
----
And to hackers who have tried firmware updates already:
If you have a nearly-working update program, and you are looking for fame, please let me know. I have a working version, but it is quick-and-dirty and relies on a specific version of the ZUNE.EXE program.

[Trogdor]

I AM SO EXCITED
more zune customizibilities yes!

[swifty]

Awesome stuff guys, keep up the good work

Hopefully we will one day have homebrew on the Zune!

That's great ZunePet. I remember you from Zune-Linux. I haven't attempted to write an update program yet but I'll give it a go. I'll assume given the fact that we're writing a new program that we shouldn't modify the Zune executable, Am I correct? And what version of ZUNE.EXE does your updater rely on? The oldest one I assume? How can I obtain this version?

Thanks ZunePet, your a huge part on this whole project. The whole community appreciates it a lot.

EDIT: If I could take a look at your updater that would be great. I'm curious to see how you approached this. And maybe I could attempt to write a more Newb friendly version based on your updater.

O sounds hella cool because i have some Japanese letters but they only show up in little rectangles or blocks w/e but all this sounds to complicated for me

Seconded. The H&M Team has been looking into Windows CE APIs for awhile, but nobody has been skilled enough to code something useful with them.

[Krebo]

Is it possible to add codecs through this method? Trivial changes shouldn't be an issue, no?

[Deiparous]

Such methodologies are largely untried, largely since it is mostly luck if they work. But such things might not happen. ZB's hack and mods team is working on finding other such anomalies as this now that it has been made apparent that there is a possibility for more serious hacks.

Yes. There is a possibility that user can upload there custom firmware cabinet file with zune software during zune update process.

[Deiparous]

As for the digital signature problems, what is worse is that it checks the signature of the contents of the cab files. So we can't even put on a fake firmware using the same method as in this hack. Getting it past the software would be easy, but the hardware checks it.

[scheme]

I mean the custom firmware cabinet file is the file that contains original firmware (NK.bin and etc.) and fonts files.

Actually, for now I'm not interested in the custom firmware, cause it is beyond my capability. ㅜ_ㅜ

[fightclub]

here is a link for a font exploit used on the xbox... this is the first font exploit i believe.. maybe applicable...

I don't know. I doubt that and as of now there is no way of proving that until we're able to recompile the cab files. But that's not what we're doing anyway. We're uploading files to the Zune's system partition (obviously nothing is checked there since we added Korean fonts) and if we could add a corrupted file to the system partition we could possibly crash the firmware.

Problems:
No way of adding files to system partition easily yet.
We need to make a corrupted file that the Zune will still try to read.
We need to write custom firmware and have the Zune run it.

This is another step but it's still far from done. So I don't think anyone should get too excited.

EDIT: That may be useful fightclub as long as that really is for a font file. It may be for some weird Xbox font file.

What are you talking about? Recompiling the cab files is relatively easy, the hard part is getting past the signature checks. What do you doubt?

[ghostz]

hey i dont understand this custom firmware stuff but what i f u make a custom one and DS the file that nedds to be DS and see if the zune takes the custom made




or is that even possible?

The cab files are checked but I doubt the Zune checks it's contents. But that doesn't matter because we can't really crack the digital signature checks even if we did recompile the cab file.

ghostz: Even if we removed the firmware the Zune has a flash chip that backups the firmware and puts it right back on.
