A lot of people have been messaging me lately asking how they can remove their Custom Firmware from PSP systems they've either bought from eBay, acquired from friends or *tsk tsk* fiddled with themselves.
This guide aims to explain simply and clearly how you can undo your actions and get back to the latest firmware (and play all the good games that won't work on older firmware).
Don't try this guide unless your system firmware is running ChickHEN, m33, or GEN firmware or a similar variation. (You can check this by viewing System Settings>System Information)
THIS GUIDE DOES NOT EXPLAIN HOW TO INSTALL CUSTOM FIRMWARE, AND THE SOFTWARE PROVIDED DOES NOT FACILITATE THIS EITHER. ATTEMPTING TO USE THIS FOR SUCH PURPOSES WILL NOT WORK AND WILL MOST LIKELY BRICK YOUR CONSOLE. THIS GUIDE IS PROVIDED FOR THOSE WITH PSP MODELS 100x AND 200x WITH CUSTOM FIRMWARE INSTALLED SO THAT THEY MAY RETURN TO OFFICIAL FIRMWARE ONLY. USE OF THIS GUIDE IS AT YOUR OWN RISK AND ANY DAMAGE CAUSED IS NOT MY FAULT.
Solved! Go to solution
Installing the Application:
Be careful and make sure you have th e right version of the application. Unlike PSP games these are console specific and the wrong one will break your PSP. 100x consoles are the original "Phat" variety, whereas the 200x models are the "Slim & Lite" models. The most obvious difference is that the speakers on a 200x are at the top of the screen, whereas on a 100x they are on the bottom. Additionally, a 100x has a mechanical switch to open the UMD drive, and a 200x is a "pull to open" tray.
MemoryStick:\PSP (Still with the GAME and RECOVERY folders inside it)
MemoryStick:\PSP1000_620-OFW.rfp (or PSP2000_620-OFW.rfp)
Returning to Official Firmware:
Now we've got the really fiddly bit out the way it's time to follow some simple instructions
The Firmware re-flash will then begin and you MUST NOT touch the console at all. Once the console performs the basic checks it will display the message "going hot now:". At that point if you remove your battery the console will be bricked. End of story. Wait for a few minutes whilst the files are written and you'll be asked to press any button to shutdown. Hit x and the console will flash the green power indicator for between 10 and 30 seconds. Once done it'll power off, simply flick the power switch again and you should boot into Official Firmware 6.2
From this point we can then update to Version 6.6, and from there we're back to the latest firmware available! Congratulations on making it this far!
