2.71系统降级1.50程序包下载

2.71用户的操作指南

降级有风险，操作时请认真按照说明进行

1) Copy the files inside MS_ROOT to the root of your memory stick.
1)将MS_ROOT里的文件复制到你棒子的根目录下

2) Wait someone with 1.50 to pass you a folder called DOWNDATER and copy it to the root of your memstick.
2)等待1.5的朋友将他生成的"DOWNDATER"文件夹传给你,然后复制到棒子的根目录下

3) It is recomended that you have the psp at more than 50% batteery and connected to AC
强烈建议psp电池电量在50%以上,而且连接充电器

4) Go to the xmb photo viewer.
4)进入xmb照片查看器

At this point will one of the following things:
到了这步还有以下事情

a) You'll see a full red screen. This indicates that the downdater is doing its job.
Wait for it to finish. When it finish it will crash on purpose. Restart your psp manually
and you'll probably have a 1.50 if nothing went wrong.
a)你会看到全红屏,这说明降级软件正在工作,请等待程序完成.当它完成之后会死机(程序中有意这样设置).手动重启然后如果没什么出错的话就会得到1.5的机子

b) You don't see the red screen. This indicates that the downdater code has not started
to execute. (even if the memstick blinks(or no), it doesn't matter! if the screen is not red, you can safely restart
the psp at this point).
b)如果没有看到红屏.这表示降级代码没有开始执行(即使如果棒子的指示灯在跳,没关系,只要屏幕没红,在这步你就可以安全的重启)

This happen because of inestability in the tiff.
Don't worry, just restart the psp and keep trying until you reach the red screen of downdate.
The downdater code is NEVER executed partially. It's either executed totally or nothing.
这是由于tiff的不稳定而造成的.
不用担心,重启然后一直试直到看到降级程序的红屏
降级代码不会不完全运行的,要么全部运行要么什么都没有运行.

It depends of "luck" but usually the downdater will start to execute in a average of 1/10 times.
Things that may increase the probabilities:
这要看你的rp了,但是通常降级程序平均有十分之一的几率开始运行降级代码
以下的东东可能会增加几率
- A fresh formatted memory stick.
- A 32 MB memory stick (and fresh formatted)
-新格式化的棒子
-32兆的棒子（而且新格式化的）
