PSP/PRO CFW

The below methods detail how to install Permanent Custom Firmware. Only do this if your PSP supports it and you know what you're doing; Temporary CFW is enough for most people.


 * 1) First, identify your PSP motherboard in the PSP/Models guide.
 * 2) Next, find out which exploit is right for you, and go to the related page.

Note: At this moment, we recommend PRO-C rather than PRO-C2, since C2 has some crippling bugs with PSX emulation; and no one seems to be around to fix it.

Glossary

 * OFW - Official Firmware. Not modded in any way.
 * CFW - Custom Firmware. Modded OFW with special features.
 * Signing - Homebrew built to work on any PSP firmware by adding Sony's Root Signing keys to them.

LCFW
LCFW is a temporary CFW exploit that gives you all the features of a permanent CFW, but is lost whenever the PSP runs out of power. It only takes three seconds to reinstall it, though.

LCFW is the safest method of installing CFW since it works on every PSP motherboard and will never result in a brick.

6.20 Permapatch
On the 6.20 firmware, there is a unique exploit that allows permapatching on some newer PSPs.

Don't worry about issues with using an older version; the features have mostly been backported, and 6.20 PRO-C2 uses a convenient exploit to run 6.60 ISOs.

Downgrade to 6.20
The Chronoswitch downgrade works by changing your PSP Model setting in flash0, bypassing security features that block 6.20 OFW. Due to security reasons, all browser settings (homepage, etc.) will be deleted, since flash1 has to be wiped in the process; make sure to back those up.


 * 1) First, install Temporary CFW for 6.60.
 * 2) Check your FuseCFG using [PSPIdent. http://wololo.net/downloads/index.php/download/1286]
 * 3) If your FuseCFG is: 0x00002A00, downgrade your PSP using Davee’s Chronoswitch Downgrader v5.0f.
 * 4) If your FuseCFG is: 0×00003300, 0x00003B00 or other, download PRE-Downgrader-fix, install and press X.
 * 5) * After installing PRE-Downgrader, use Davee’s Chronoswitch Downgrader v5.0f to downgrade to 6.20.

Once you've downgraded using Chronoswitch, you can now follow the instructions to install the 6.20 Permapatch.

Upgrading past 6.20 after Chronoswitch
After installing 6.20 Chronoswitch, you will need to use a special app to update to 6.35 or 6.60 if you so choose. (need to find that app)

However, this is not recommended or helpful, since 6.20 PRO-C contains all the features of 6.60, and has patches that allow 6.60 games to be played.

Chronoswitch is now working for all PSP motherboards except PSP GO
 * Note: There have been unconfirmed reports that TA-095v2 (09g) is unable to downgrade back to 6.20 after upgrading.
