If you have not downloaded the file from the "what you need step", download it and extract it using win rar.(oh yeah.....install winrar first) =P4. you will be prompted with a flash screen (recovery mode ,main menu)9. keep tapping "O" and you will be prompted with the default setup as you did when you first got your psp.12. I've been checking out a few "how-tos" before removing the custom firmware and the reason why there's complaints earlier than this posting because this article doesn't explain that this will only work with the original PSPs or the "PHATS" and that some people would rather have a waaah and blame the poster than try to find out it failed.
Press and hold down the right shoulder button while powering on the psp. When done, manually restart the psp by completely shutting down again. When powering back on, you will see a blue error screen with lots of words in different languages on it.

This is designed to remove custom firmware easily and restore a classic 1.5 firmware back to your psp. Version 1.5 firmware does not work on the 'Slim" or later models and will 'brick' them.
Up to this point, all you've done is to set the PSP's Network Update function back to downloading official firmware instead of custom firmware. At the end of step 4, your PSP Slim will have restarted.
Now using the XMB locate the System Update option under Settings.
Again using the D-pad, push up or down until the option titled M33 Network Update is highlighted. Press the X button and the menu item should read Disabled.
If the option already reads Disabled, then there's probably a good chance that the custom firmware has never been updated by download direct to the PSP and it's still cool to go to the next step. Highlight Back and click X (back to top menu) then highlight Exit and click X.

I haven't touched my PSP in months (lol Sony) so when a decent looking game finally comes out I decide to rent it. Pop the sucker in and of course I have to upgrade from 3.x to 5.x - but my battery is dead since it's been so long. Pop the sucker in and of course I have to upgrade from 3.x to 5.x - but my battery is dead since it's been so long. Reading these posts it makes sense because I can see how a PSP dieing mid-upgrade would cause a brick. Now I just need to learn how to transfer save files to and from PSP and PS3 and I'll be good to go. it's like this i have a 5.50 gen-d2 software on my psp but i accidentally pressed something then it downgraded by itself to only 5.50!!! i tried many steps but i think i that i should do it step by step to upgrade it.

Do you really want to go back to official firmware?
There are really no downsides to custom firmware..it doesn't really matter to me which firmware i'm on i just want the psp to work.
