Descargar Chronoswitch Downgrader version 6

-> Added support for 6.61
-> Added support for 09g units to 6.20
[What does it do?]
Allows users who are incontent with their firmware to downgrade to 6.20 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)
[I'm a dev, sup?]
