[VERSION 7.0]
    -> Added support for Infinity

[VERSION 6.1]
    -> Added support for 11g units to 6.60

[VERSION 6]
    -> Added support for 6.61

[VERSION 5]
    -> Added support for 09g units to 6.20

[What does it do?]
Allows users to downgrade their PSP using the Sony Updater.

[How do I use it?]
Copy the "PSP" folder to your PSP. The downgrader is "signed" and can be launched from OFW XMB. You need to copy the 6.20 update to PSP/GAME/UPDATE/EBOOT.PBP and for PSPgo it must be the eflash it is placed on. After setup run the downgrader and follow the onscreen instructions.

[What does it technically do?]
6.20-6.35: It uses the utility/power exploit to gain kernel access and reboots into the updater with a special PRX running. This PRX uses the pspdecrypt functionality to decrypt the updater PRX when needed. This allows the updater to boot in the newer firmwares.
6.38/6.39: It uses my http_storage exploit to gain kernel access.  Basically, http_storage has a vulnerability in it, where I can write -1 to anywhere in memory.
6.60: Uses sceNetMPulldown to gain kernel access.
6.61: same as 6.60 (only certloader kexploit is patched in 6.61)

该用户已被禁言

刚刚试了然并卵，依然不能把最后一批出厂的09G 6.60 降回6.20

这个是6.61 Infinity专用的，听我群友说官方6.61用Downgrader 6.0的降级程序把6.61降到官方6.60，再降到6.20。不过据说，6.61 Infinity用这个降级容易中招。

中招指的是变砖？现在有安全6.61无限降级的方法吗？
