注意：TA-082 版的PSP用户不要运行此程序！！！否则变成板砖不要扔我
使用方法：
这个完全版包括降级器和所需的其它文件
这个软件是免费的…………（貌似不重要，不翻了），需要用1.50版配合使用
1.50用户的使用步骤
-------------------------------
1、拷贝downhelper和downhelper%文件夹到1.50主机记忆棒上的 /PSP/GAME/ 目录下
2、搞一个1.50升级程序（请用google）放到记忆棒的 /PSP/GAME/UPDATE 下
3、运行downhelper程序，他会获得必要的文件
4、完成后程序会推出，你现在能删除调 /PSP/GAME/UPDATE 下的升级文件了
5、注意看，你的记忆棒根目录下会有一个叫 "DOWNDATER" 的新文件夹，这个是2.71需要用的数据文件
2.71用户的使用步骤
-------------------------------
1、拷贝降级器到你记忆棒上的 /MS_ROOT/ 目录下
2、拷贝刚才在1.50上生成的 DOWNDATER 到你记忆棒的根目录下
3、请先检查你的PSP有多于50%的电力并插上了电源
4、进入系统自带的看图功能
5、下面，会发生两种可能：
a:你会看到一个完全红色的屏幕，这表示降级器正在工作中，等它完成，当完成的时候会死机，不要惊慌，手动重启你的PSP，如果没有意外你的PSP就是1.50的了
b:没有看到红色屏幕，降级代码没有运行，别担心。如果屏幕不是红色的，你可以安全的重启PSP
OK，降级到此结束。
使用方法原文：
This is the FULL version, which includes the required DOWNDATER folder and related files.
This software is free, unlicensed and comes with no warranty.
Despite it has been tested and it has worked, a program that rewrites a big part of the flash (flash0) is always dangerous. You are the only responsable of whatever happens to your psp using this unlicensed program.
This program requires that someone with a 1.50 runs a little program and send you the output so you can init the downdate process. (by legal reasons i cannot provide those files directly, that's why this is needed).
The 1.50 program is TOTALLY safe, it only dumps the flash of a 1.50 user and it also extracts some special
prx's found in the 1.50 updater.
The downdater directory outputted is exactly the same than the created by the 2.60/2.50 downdater.
IMPORTANT NOTE: TA-082 users, this doesn't work on these psp's. DO NOT RUN IT.
Instruction for the 1.50 user
-----------------------------
1) Copy the folders downhelper and downhelper% from the folder 1.50 HELPER folder to
/PSP/GAME/ in your memstick.
2) Obtain the 1.50 updater EBOOT file (Google) and put it in /PSP/GAME/UPDATE in your memstick.
3) Init the downhelper program.
It will dump your flash and some files from the updater eboot to the memstick.
4) After that, the program will exit. You can now delete the updater from /PSP/GAME/UPDATE
5) You'll notice that you have a new folder in the root of your memstick called "DOWNDATER".
That's the folder you'll have to send to a 2.71 to let him use the downdater.
Instructions for the 2.71 user
-------------------------------
1) Copy the files inside MS_ROOT to the root of your memory stick.
2) Wait someone with 1.50 to pass you a folder called DOWNDATER and copy it to the root of your memstick.
3) It is recomended that you have the psp at more than 50% battery and connected to AC
4) Go to the xmb photo viewer.
At this point will one of the following things:
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.
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).
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.
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:
- A fresh formatted memory stick.
- A 32 MB memory stick (and fresh formatted)
Many thanks to:
- Person that found and exploited the tif bug: Nopx86
- hitchhikr for finding the kernel exploit.
