3.50可以软降了!附中文教程

今天noobz组织终于放出的官方3.50的降级程序,一如我们所知道的，一张音乐方块的UMD是必不可少的，但暂时只支持美版和欧版，日版暂不支持。

Here are the steps to downgrade any 3.50 PSP to 1.50:
降级步骤
1  - If you have a 3.50 PSP skip to step 6
      如果你的PSP已经是3.50的固件，请直接到第6步。

2  - Download 3.50 update from here:
        http://dl.qj.net/PSP-Firmware-3.50-(North-America)-PSP/pg/12/fid/13840/catid/163
      下载3.50固件 http://dl.qj.net/PSP-Firmware-3.50-(North-America)-PSP/pg/12/fid/13840/catid/163
3  - Unzip and place the file in <pspdrive>:/PSP/GAME/UPDATE
      解压并放入记忆棒的 <pspdrive>:/PSP/GAME/UPDATE  文件夹内
4  - On the PSP, run the 3.50 update from the memory stick under the Game menu.
      在PSP上运行3.50的升级程序
5  - Delete <pspdrive>:/PSP/GAME/UPDATE
      升级完成后删除3.50的升级程序
6  - Copy the contents of the folder MS_ROOT from the 3.50 downgrader ZIP to
     the memory stick
     复制降级包中的MS_ROOT文件夹内的PSP文件夹到记忆棒根目录（最好事先把记忆棒先格式化下，但不是必须。）
7  - Unzip the 1.50 update to a temporary folder. Rename the EBOOT.PBP to
     UPDATE.PBP and copy it to <pspdrive>:/PSP/GAME/UPDATE/ .   DO NOT
     OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP!
     解压1.50的升级程序到一个临时文件夹，并把EBOOT.PBP 更名为UPDATE.PBP，
    然后复制到<pspdrive>:/PSP/GAME/UPDATE/
    不要覆盖 PSP/GAME/UPDATE/EBOOT.PBP文件  切记要改名
8  - Load Lumines and press x to start the game
      运行音乐方块游戏
9  - The screen will clear to black and fill with a light blue colour, then
     the PSP will reset itself
      屏幕将变黑然后变成蓝屏，随后PSP将自动复位
10 - Check that HEN is running by going to system settings, then to
     "System Information" and it should show up as system version
     350 HEN
     检查系统信息 中的系统版本是否是 350 HEN

11 - If it is showing up as HEN then go to the memory stick and
     run the x.yz update
     如果上步没有出错，运行游戏下的 x.yz update 程序
12 - If you have an unpatched TA-082 or higher motherboard, you will be
     prompted to allow the downgrader to patch your motherboard so it
     can be safely downgraded.  The downgrader will not let you proceed
     without patching, if your motherboard requires it.
     如果你是一个TA-082或者更高级的主办，你将被程序引导为你的主板打补丁来更安全的降级
13 - Before the downgrader does anything to your PSP it will ask
     for you to agree to what it is doing, if you no longer want to
     continue press the Right Shoulder Button (R-TRIGGER).
     在降级之前，程序将询问你是否确定要降级，如果不同意，请按R-TRIGGER
14 - Once you have agreed to start the downgrade do not unplug the
     PSP, or try and restart it
     一旦你同意降级，请不要动任何案件或者复位PSP
15 - Once finished the PSP will ask you to press X, and reset itself
       降级完成后程序将要求你按X键来从起PSP
16 - If it comes up saying that the settings are corrupt, press x
     to continue, this will mean you will need to re-enter the
     settings for network connections into your PSP, otherwise go to
     step 18
     如果提醒设置破损，按X继续，这意味着你将从新设置你的PSP 网络连接设置。
     如果没有提示  直接进入18步
17 - Load the included NetConfigBackup application in your PSP, and select to
     restore, this will take the backup that was done of the network config
     that was done automatically during the downgrade.
     运行NetConfigBackup 程序在PSP上，选择 restore 来修复 你的PSP网络设置
18 - All done now :-)  Hopefully you now have a 1.50 PSP.  Enjoy it responsibly.
      所有降级步骤完成，您现在已经有了一个固件版本为1.50的PSP，Enjoy it 。
