Robinsod, in cooperation with Team Infectus and others from the Xboxhacker forums have a "proof of concept" in regards to downgrading an Xbox 360 kernel. Some modding enthusiasts will remember that on January 9th, 2007 an unexpected Xbox Live Dashboard update was released. Xbox Live director, Major Nelson had this to say about the update:

Quote:
Earlier today the team pushed out a dashboard update over Xbox Live. There is nothing major in this one, it just addresses a few performance and stability issues.

In truth, it turned out that this update, which is Kernel and Dashboard version 4552, fixed what we call the "hypervisor exploit." This exploit allowed modders to create a modified King Kong game disc, and booting this would let the modder run the machine in hypervisor mode, allowing unsigned code. In layman's terms that means that with the Xbox 360 kernel version 4532 (Fall 2006) and kernel version 4548, the system was capable of running Linux or other unsigned code. An additional bonus was that the 4552 update prevented downgrading the Xbox 360 kernel. Before this update, it was possible to change kernel versions freely.

Since this time, a lot of research and work has been into finding a way to downgrade an Xbox 360 kernel. The next step they found was that if you have your console-specific, individual CPU key, you could downgrade the kernel. Meaning, that if somebody had taken the time to run Linux when they had kernel version 4532, and use Linux to get their CPU key, they could upgrade to version 4552 or newer, and still be able to downgrade at a later time. This was a huge breakthrough, because it was like a shimmer of hope. Before this, it was thought that if you didn't take precautions before the 4552 update, there was never a chance of downgrading. Now, if a person could somehow find their CPU key, they could downgrade their Xbox 360. The problem shifted from finding a way to downgrade, to finding the CPU key.

Fast forward to about a month ago. A theory was posted by Xboxhacker member arnezami. Instead of trying to find the CPU key, why not find the hash instead? The theory was that, in order for a hash to work, it has to check the kernel against a stored hash, and it does this on a byte-by-byte basis. They needed to find two hashes, one for the CB section and one for the CF section, both hashes are 16 bytes long. Essentially, one would go through every possible value for a single byte, recording the time it takes for the Xbox 360 to fail. When the first byte fails, the Xbox 360 fails right then. When the first byte is correct, the Xbox 360 then proceeds to check the second byte. This small difference in time must be large enough to be able to clearly identify. Using an Infectus modchip, Robinsod went through every possible value for the first byte, recording the time. One attempt was longer than all the others. He had found the first byte. This was repeated until every byte from both hashes was found. And, in the end, over a span of three nights, Robinsod had succeeded in downgrading an Xbox 360 without knowing the CPU key.

This was purely a proof of concept at this point. Much more work needs to be done - like limiting the hardware needed to replicate this, fixing some minor bugs, and trying to automate the process. At this time, it is a very long and diffi*** process. Here's hoping that it will get faster, easier, and cheaper. Right now it looks like folks interested might want to purchase an Infectus modchip.

This process would downgrade the kernel to version 1888, the original version when you first powered on the system. This can then be upgraded to kernel 4532. Then you can run Linux to find your CPU key and fuseset values. You can also use an xD memory card and installed reader to boot a different kernel just by inserting the xD memory card you want. Imagine a card for kernel 4532 to use Linux and run homebrew, a card with the latest kernel to use on Xbox Live, and even cards for different regions (you could switch between NTSC and PAL).

Hopefully this will push homebrew development for the Xbox 360, which right now is nonexistant. The only homebrew making use of the hypervisor exploit right now, is Free60 Linux. With everybody having the ability to downgrade their kernel and use the hypervisor exploit, it would be nice to be able to run programs like Xbox Media Center, classic system emulators, and alternate dashboards.

For all of you people who just care about playing backups and using modified firmware, this has nothing to do with you at all. But I promise the next news update will be DVD firmware related. .

最后一句让人期待啊

Robinsod, 在与队Infectus 和其他人合作下从Xboxhacker 论坛有concept" "proof; 关于降低Xbox 360仁。一些modding 的热心者记得, 在2007 年1月9 日一次意想不到的Xbox 活仪表板更新被发布了。Xbox活主任, 主要纳尔逊有这说关于更新:

行情:
队更加早期的今天推出了一次仪表板更新在Xbox活。有没什么主要在这一个, 它正义地址几表现和稳定问题。

实际上, 它结果, 这次更新, 是仁和仪表板版本4552, 固定了什么我们称"hypervisor exploit." 这盘剥允许modders 创造一个修改过的Kong 国王游戏圆盘, 和孕穗这会让modder 运行机器在hypervisor 方式下, 允许未签名的代码。用意味的layman's 术语以Xbox 360 仁版本4532 (秋天2006) 并且仁版本4548, 系统是能跑Linux 或其它未签名的代码。另外的奖金是, 4552 更新防止降低Xbox 360 仁。在这次更新之前, 它是可能自由地改变仁版本。

从这时间, 很多研究和工作是入发现方式降低Xbox 360 仁。他们发现的下步是如果您有您的控制台具体, 单独CPU 钥匙, 您能降低仁。意味, 那如果某人需要了时间跑Linux 当他们有仁版本4532, 和用途Linux 得到他们的CPU 钥匙, 他们能升级到版本4552 或更新, 和仍然能降低等级在最新时光。这是巨大的突破, 因为它是象希望淡光。在这之前, 它被认为如果您didn't 作为防备措施在4552 之前更新, 那里从未是降低等级的机会。现在, 如果人能以某种方法发现他们的CPU 钥匙, 他们能降低他们的Xbox 360 。问题转移了从发现方式降低等级, 对发现CPU 钥匙。

快速今后对大约一个月前。理论由Xboxhacker 成员arnezami 张贴了。而不是设法发现CPU 钥匙, 为什么改为不发现回锅碎肉? 理论是, 为了回锅碎肉工作, 它必须检查仁反对被存放的回锅碎肉, 并且它做这根据字节由字节依据。他们需要发现二hashes, 一为CB 部分并且一个为锎部分, 两hashes 是16 个字节长。根本上, 你会审阅每可能的价值为它需要为Xbox 360 对失败的一个唯一字节, 记录时间。当第一字节失败, Xbox 360 然后失败。当第一字节是正确的, Xbox 360 然后进行检查第二个字节。这小时差必须是足够大的能清楚地辨认。使用Infectus modchip, Robinsod 审阅每可能的价值为第一字节, 记录时间。一企图比所有其他长的。他发现了第一字节。这被重覆了直到每个字节从两hashes 被发现了。并且, 在最后, 在三夜间距, Robinsod 成功降低Xbox 360 没有知道CPU 钥匙。

这这时纯净地是概念证明。更多工作需要被完成- 象限制硬件必要复制这, 修理某些未成年人烦扰, 和设法自动化过程。此时, 这是一个非常长和困难的过程。Here's 希望, 它快速地将得到, 更加容易, 和更加便宜。它现在看起来象伙计感兴趣也许想要购买Infectus modchip 。

这个过程会降低仁对版本1888 年, 原著当您第一次供给动力了在系统。这可能然后被升级到仁4532 。然后您能跑Linux 发现您的CPU 钥匙和fuseset 价值。您能并且使用xD 存储卡和安装的读者解雇一个另外仁由插入您要的xD 存储卡。想象一张卡片为仁4532 使用Linux 和跑homebrew、一张卡片以最新的仁使用在Xbox 活, 和甚而卡片为不同的地区(您能交换在NTSC 和PAL 之间) 。

有希望地这将推挤homebrew 发展为Xbox 360, 现在是nonexistant 。唯一的homebrew 现在利用hypervisor 盘剥, 是Free60 Linux 。用大家有能力降低他们的仁和使用hypervisor 盘剥, 好能运行节目象Xbox 媒介中心、经典系统仿真器, 和供选择仪表板。

你们大家正义关心关于演奏备份和使用修改固件的人们, 这吃没什么做与您根本。但我许诺下次新闻更新将是DVD 固件被关系。
凑合着看哈………………………………………………

你们用的翻译引擎太烂了。。。。

太烂太烂，还不如自己看。

我晕啊....什么跟什么.....完全看不懂......直接看英文算了...

谁能说个大概什么意思呀
