原帖内容：

I present to you my port of Davee's 6.35/6.31 downgrader to 6.38.
This a very simple app, just put the official 6.20 updater in (ms0/ef0 accordingly)PSP/GAME/UPDATE, and run the downgrader, this will reboot into the 6.20 "update", and allow you to downgrader to 6.20. Has been tested on 1k, 2k, 3k, and Go (doesn't support 07g or 09g, although, I might add support for them to go to 6.35 instead of 6.20, sometime in the near future).
I will be releasing the source on May 29th.
Thanks:
To Davee for making the original 6.35/6.31 downgrader
To ultimakillz and skyend for being my mentors when I first entered the scene.
To n00b81 for teaching me a lot of things.
To Davee, Freddy, TheLemonMan, Hellcat, and Draan for answering any question's I've had.
To TiPi and Nymphaea for allowing me to work on their VSH sploit, which gained me alot of knowledge and experience.
To Npt for hosting such an awesome competition!
And to many others that I'm probably forgetting.

No screenshots added because it's only text (splash screen as pic1).
Important note: You run the application at your OWN risk. I am not held accountable if you ** up your PSP.
Another important note: After you downgrade to 6.20, you will get a BSOD (saying that your system information is corrupted), this is OK, just click circle to reset your system information and you will be back to normal.
Final important note: It *should* still support 6.35/6.31, but I haven't actually tested it. I don't see why not though, all of it is in firmware detection.

Make sure you have a PSP Model below 07-09g first.
1. Grab the 6.20 UPDATE EBOOT.PBP and place it at PSP/GAME/UPDATE
2. Place the downgrader in PSP/GAME/638 Downgrader/
3. Run the downgrader, follow the instructions and then wait for it to boot the 6.20 OFW Update
4. When PSP Reboots press O to reset settings, Enjoy.

操作翻译：

首先确定你的PSP主板低于07-09g
1 把6.20的EBOOT.PBP放入：PSP/GAME/UPDATE
2 把downgrader放入：PSP/GAME/638 Downgrader/
3 运行downgrader，按提示操作，然后等待6.20 OFW升级画面的出现
4 升级完毕，PSP重启后按O恢复设定

试了一下
肥P1000 用这个。。。可以进入6.20升级程序。
然后自动重启...提示设定（日期什么的）损坏。..按O修复。
再次进入确认一下。。的确是……6。20、、
