NOTE:
If you have a TA082+ motherboard and you downgrade to 1.50, currently you will be unable to upgrade to 3.30+ Sony firmware. This is due to Sony blocking updates when the PSP has been modified to run 1.50. There will be an application released later which will allow users to revert the changes. If you are using a TA082 motherboard then I would suggest just using 1.50 or OE until an application is released.
WARNING, ANY DOWNGRADER HAS A CHANCE OF BRICKING A PSP. WHEN A PSP IS BRICKED YOU WILL NOT BE ABLE TO USE IT ANYMORE. PLEASE TRY THIS AT YOUR OWN RISK. Well like other downgraders it has its own risk too .
INSTRUCTIONS :
1) Download the downgrader pack from
2) Connect your PSP to your PC via USB
3) Open the file with winrar and copy the PSP folder to the ROOT of the PSP , if it asks you if it can overwrite click on "Yes" .
4) Load Lumines and press x to start the game
5) The screen will clear to black and fill with a light blue colour, then the PSP will reset itself.
6) Check that HEN is running by going to system settings, then to"System Information" and it
should show up as system version 350 HEN
7)If it is showing up as HEN then go to the memory stick and run the x.yz update (1.50)
8)If you have an unpatched TA-082 or higher motherboard, you will be to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it.
9)Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing, if you no longer want to continue press the Right Shoulder Button (R-TRIGGER).
10)Once you have agreed to start the downgrade do not unplug the PSP, or try and restart it
11)Once finished the PSP will ask you to press X, and reset itself
12) If it comes up saying that the settings are corrupt, press x to continue, this will mean you will need to re-enter the settings for network connections into your PSP, otherwise go to step14
13) Load the included NetConfigBackup application in your PSP, and select torestore, this will take the backup that was done of the network config that was done automatically during the downgrade.
14) All done now *yaaaaa* Hopefully you now have a 1.50 PSP . To update to a 3.40 OE-A (the best custom firmware that allows you to play iso's and homebrews click here .
Troubleshooting
If when trying to restore the network config using netconf backup you find that it gives you an error on the downgraded 1.50 PSP, try adding a temporary network config, then deleting it and run the netconf backup again.
