近日,关于3.50系统降级以及“神奇电池â€的传说已经广为流传。在网络上有人号 称可以将所有版本的PSP软件降级至
1.50,哪怕是最新的3.50系统主机都能轻而易举的被搞定。这一说法刚刚传出,立刻遭到了许多人士的质 疑:凭借往日
对于降级的一些消息和“常识â€这种降级显然是不可能的。之后,为了证明自己说法的 真实性,当事人上传了一段视频
,在视频里清除的看到当事人将一台全新的系统为3.50系统的PSP降级为了2.71。这立刻在网络上引起 了轰动。并且由
于降级过程中使用到了一块神秘的电池,不明真相的网友,立刻由此引发了大胆的假设:电池可以降级!但其实, 电池
只是作为钥匙,开启了PSP的工厂模式。而这次的降级其实是一次“修复†工程。
3.50 downgrading and the lengedery magic battery have been on the internet for quite a long time.
Someone claims that they could downgrade any FW PSP to 1.50 including the newest 3.50. Few people
believe them, because... only a battery??? Several days ago, a guy (saleclerk in a game shop in
Shenzhen China) posted a video clip of sucessfully downgrading a 3.50 to 2.71, in this video, he
seems to try to hide something when he loaded the battery on the PSP, which makes more people think
it might be the MAGIC battery.
Well, actually, the battery is only a key, a key to open "Factory Mode" on the PSP. And this
downgrading process is actually a "recovery" process.
为了揭开这次降级事件的真相,levelup.cn特别观察员琥珀以及《掌机王SP》编辑米格特别前往 进行调查采访以及
拍摄。再次感谢相关人士对本次采访的支持(由于某些原因,以及事先的协定,在此不方便透露相关人士的更多情 况,
敬请谅解)。
To clear this up, the "special speculator" on levelup.cn, Hupo aka amber (I don't know to translate
the exact word, you can take him as a moderator) and an editor from "King of Portable Consoles SP"
Mige, found this man, had an interview and took another downgrading video clip. The identities and
backgrounds of the other people who are involved in this article will not be exposed as they agreed.
在文章开始之前,先给出一张List,让大家有个心理准备
·降级是真的,并且可以对付任何版本主机
·电池确实不是普通电池,是特质的
·电池不是降级的主角,而是一把钥匙。降级的主角还是记忆棒里面的程序
First of all, a list:
1. the downgrading is real, and it's good for any FW PSP
2. the battery is NOT an ordinary battery in our PSP, it is special
3. the battery is ONLY a key, the most important part is the programs in the memory stick
现在我就开始一步一步的来分析这次降级吧,降级的过程其实简单分为三个步骤
The downgrading process is in 3 (here is a typo in the original article, 4 steps actually) steps
第一步:打开记忆棒仓盖,装入存有神秘程序的记忆棒。前文说过“神奇电池â€仅仅是 一把钥匙,降级的主角还是记忆
棒里面的程序
1. open the cover of the battery compartment, put in an ordinary battery, install the memory stick.
Again, the "magic battery" is only a key, the most important part is the programs in the memory
stick
第二步:关机,卸下普通电池。并且连接上安全可靠的外置电源,然后将“神奇电池†放入电池仓,神奇电池并不能给
PSP供电进行降级。
2. shut down the PSP, uninstalled the ordinary battery. Connect the PSP to AC, put the "magic
battery" in
第三步:拨动电源开关,启动PSP。当屏幕上显示出特定画面时即可取下“神奇电池†,让PSP完全由外接电源供电。这
时已经开始执行降级程序,并开始对固件芯片进行操作。
3. turn on the PSP. when the screen shows some special information, take off the "magic battery",
and now the PSP should reply on the AC only
第四步,当记忆棒指示灯停止闪烁,并且在屏幕上出现OK画面,表示操作已经完成时即可关闭电源,取出记忆棒 ,然
后重新开机,这时系统版本显示应该为2.71。
4. when the memory stick stops blinking, and the screen shows "OK", it means the whole downgrade
process is finished. turn off the PSP, take out the memory stick, reboot, the FW should be 2.71
电池:
Battery
细心观察的玩家一定发现,PSP的电池接口有三根金手指。而多出来的第三根金手指附带有其他的作用,根据先 前SONY公
布的一些情报来看,PSP的电池是附带有信息识别功能的,也就是说主机会检测电池的身份是否合法,然而这对 于国内的
组装电池生产者来说形同虚设。尽管如此,我们取得了一个很重要的信息,PSP对于电池具备一定的信息检测机 制。而在
这次降级的过程中,这块“神奇电池â€就更进一步的发挥了这一机制的作用:PSP启 动后,在没有读取任何固件信息的情
况下首先读取电能供应机关——电池上的信息;而神奇电池上的这段信息则告诉P SP进行一项特定的任务——读取记忆棒
。
Take a closer look at the battery, we could see that it has three "gold fingers" (pins ?). The extra
third one has its special mission. According to the earlier information from SONY, this battery
could identify information, which means that the PSP could check whether the "magic battery" is
legal or official. However, this identity checking for the clone manufaturers in China is nothing.
In this downgrading process, the battery proves the function: when boots up, the console didn't read
any FW data, but reads the data on the battery. Then the battery told PSP to do another task -- read
the mem stick
这一过程完全是不通过PSP的固件系统芯片控制的,而是更加底层的“工厂模式â€, 所以之前尽管Dark_AleX对于PSP的
系统固件进行了地毯式的研究和解析仍然没有发现这个特殊的存在。
This process is not through PSP FW chip, but a even lower level "factory mode", so I guess this why
although Dark_Alex masters every single detail of FW, he didn't find this mode.
当PSP被要求在加载系统程序前读取记忆棒,那么可以做的事情就很多了。因为这里已经完全将系统固件隔离了 ,也就不
存在什么高版本低版本,哪怕系统已经由于误操作而完全无法启动(变砖),仍然可以使用工厂模式 来重写系统。
打个比方,这种方式就好比用系统引导盘重装系统,你只需要一张能够引导系统的光盘即可;而此前的降级就好比 在
WinXP下重装系统,你不仅仅需要安装光盘,你还需要一个能正常运行的系统。
When the PSP is required to read the mem stick before load FW programs, there are lots of things we
could do. Because it doesn't matter higher or lower FW on this PSP, we could rewrite it now. It's
like you use a bootable CD reinstall your windows system, all you need is a BOOTABLE CD. You could
install Win98 if you are in WINXP.
记忆棒:
Mem stick:
电池起到了“钥匙â€的作用,开启了PSP的工厂模式,让PSP在加载操作系统前先 读取记忆棒上的程序。那么记忆棒上到
底有些什么神奇的程序呢?由于先前的保密协定,这里不能直接透露这个程序的名字,然而可以告诉大家的是,这 个程
序的作用就是向固件芯片写入系统程序。这个过程其实和我们通常意义上说的降级没什么区别,不过就是写入一个 特定
版本的系统而已。
OK, the battery is a key that opens "factory mode". Now we move to the mem stick. As agreed, we will not expose the name of this program, what we could say is the function of this program is to write FW. This process is not different from what we call downgrade in general, but just write to a specific FW 2.71.
细心的玩家,看完前面的降级过程介绍,肯定会产生一个疑问:为什么从3.50
降到的是2.71而不是1.50?这个问题其实很简单。因为2.71系统是支持TA-086主板的最低版本系统。在工厂模式下所使
用的其实还是SONY官方的系统文件,因为非SONY官方系统是无法通过工厂模式的校验的。而在没有打补丁 的前提下,
TA-086主板是无法直接运行1.50系统。而Dark_AleX也是花费大半年时间的不断摸索和研究才制作出 了TA-82/TA-086主
板运行1.50系统的补丁,并由此制作了通用型2.71降级程序。使用工厂模式“降级â 到2.71,然后再用Dark_AleX的通
用降级程序降至1.50是最为安全和可靠的做法。
Then, why 2.71? Because 2.71 is the lowest FW that TA-086 supports. Even under "factory mode", the program is still using official FW from sony, unofficial FW (homebrews etc.) will not pass the "factory mode" checking in the first place. And if w/o patch, TA-086 doesn't support 1.50. Dark_Alex et al., put lots of time on this patch and successfully gave us a universal 2.71 downgrader. Therefore, the best way to do (if we could) is to downgrade higher FW to 2.71 with this "factory mode", then use Dark_Alex's downgrader back to 1.50.
这次降级的意义:
尽管3.50系统的“音乐方块降级包â€已经推出,但本文所提及的这种降级由于是一 种“工厂模式â€的固件操作行为。对
于3.60乃至更高版本的系统降级都具有极其重要的意义,由于无需主机系统的支持,对于已经变砖的机器也能 轻而易举
的实现恢复。如果工厂模式能够破解而无需使用神奇电池启动,那么PSP的破解将进入一个新的篇 章。
If it also works on FW3.60, or if we could get in "factory mode" w/o the battery, it will be
great...blah blah blah
