mfi.re/?dhq6etclola41av/ chronoswitch v7

Read me:

Code: Select all

[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)

[Credits]

Hi toBsucht,

Since Daave's website is down.
I'm just wondering that do you have updated link for chronoswitch by chance?

Cheers,

Butcher

@haightc
Welcome to Wololo.net
If you like to downgrade run Chronoswitch on cfw/hen. It works on ofw as updater only ;)

edit:
A little sitenote on my Infinity update-downgrade 6.61

My internet connection did not work as i was back on 6.61 ofw, just connecting to network was possible!
So i downgrade to 6.20ofw (deepest possible on my 3004 / 4g). Now it works again as befor :mrgreen:
My fav radio!!! Pretty sure some people get same bug
