51.1.2.0_user_512073320 Source Code Uploaded

AFTVnews.com · Aug 18, 2014

Amazon has already made the current "root blocking" software update's source code available. This is a bit strange since for the previous version, 51.1.1.0_user_511070220, they didn't upload the source until the update was "official" (i.e., their documentation page listed it as the latest version).

I've created a page at AFTVnews.com/software to keep track of all the Fire TV software versions. Feel free to comment on the page or in this thread if I'm missing any information, or I have something listed incorrectly.

So I think I am going to call shenanigans on Amazon. The kernel source is the same between 51.1.1.0 and 51.1.2.0, yet towelroot, which exploits a kernel bug stopped working. If they fixed the kernel to patch the exploit, it should show up in the diff.

perhaps puts to the kernel build tree is frozen. it may be a simple file change which breaks it. They released the code to show you where it wasn't so you could undo. I'm sure there is a smart developer who knows leaving it open to towelroot means more device sales. he just has to appease his boss who was given the call "shut it down"

That's very interesting. So you're saying it looks like they explicitly blocked towelroot without patching the exploit that towelroot uses?

No. I think they patched the kernel but didn't include that change in the source drop.

Is it possible that towelroot may still work on the latest update with some tweaks to the modstrings?

Ah, ok. That does make more sense.

If I put trust in Amazon that they didn't slip a change in the kernel without putting it in the source drop, then that's a possibility. I don't really know much about towelroot, but I did notice about the modstrings when I was reading about it.

I guess the only way to tell would be to diff the firmware update instead of the source?
