Don't listen to Natahan, Studguy17. Natahan doesn't understand that you are trying to unbrick your psp and downgrade to firmware 1.5 where you can then upload and install custom firmware made by either m33, noobz or someone else that will allow you to play games downloaded off the internet for free. As for 3.80, I'm not quite sure if the proper files have been developed yet as 3.80 is a fairly recent firmware. I'm sure you have heard of the pandora battery and magic memory stick. If you haven't this won't make much sense so research it and read this again. The pandora battery in conjunction with the magic memory stick(mms) is used to unbrick your psp slim(psp 3000). In this case there are files that are created for us to place on our mms to match the firmware we are trying to downgrade. Once the appropriate files have been released for 3.80 most google searches will come up with it. Once downgraded, you'll then want to update it with custom firmware provided by hacking teams like m33. This is so you can still enjoys the fruits of Sony's updates and still play your free games. Firmware update files with names like 3.71m33 or 3.50m33 have nothing to do with the process of downgrading your psp they come into play after the downgrade is complete.

Tip: If you are frequenting any psp hacking related forums, pay attention to the names of the hackers being mentioned and google them to see of they have any of their own websites with firmware updates on them.

It's impossible to downgrade your PSP from it's current version. I'm not quite sure why you'd want to downgrade, but maybe you should upgrade (If a version is available) again and see if you like that version better. ^-^

Use a pandora battery to flash anny firmware you like.

You have updated your custom firmware with the original firmware from Sony.

You'll have to downgrade your firmware to update to the newest custom firmware using the pandora battery or update using the pandora battery to update directly to the newest custom firmware build.

Succes.

I dont know how to degrade my psp version so i can use PSPtube


Sony has blocked access to homebrew since 1.51. The higher the version the harder to degrade.

The M33 installer is considered as homebrew.

You need to downgrade to 1.50 with a pandora's battery and a MagicMemoryStick.

Buy one at http://www.ebay.com/

The you will be able to use the M33 installer.

The "Data is Corrupted" is a hoax for sony to trick players into deleting the Very, oh so, Very UNcorrupted Application.

Downgrade psp 5.01 to 5.00 m33


If you are on psp 3000 series then you will have to live with it and buy UMDs for the time being.If not you can get a pandora battery and downgrade it to whatever you want.Since you are on 5.01 OFW I highly doubt your mobo is still trigger-able by pandora battery though.
