Want to fix my psp (fat) on 3.03 oe-a firmware and trying to update it and it keeps on saying DADADADA error

DADADADA is an error code that dax made so that you couldn't upgrade to official firmware from custom firmware. If you want to get rid of your custom firmware, you have to recover back to 1.50 and then upgrade from there.

suggest downgrading to custom firmware

You need to update the firmware to GEN 5.5C. This will then allow you to play all games. Have fun!

you can't update your psp from custom firmware(what you have) to official firmware (what your trying to get to) What you need is to upgrade your firmware from OE-A to M33. All you need to search for is 3.51 m33 creator.

I suggest you stick with 3.90 M33 Custom Firmware because the old and good games can't be read with the latest versions

go to the playstation network site click psp and system updates and you can update it from there.

Hello Sir =)


DADADADA - Running a FW Update in DAX custom FW

make sure you've created a upgrade folder and make sure when you name it its like this: UPGRADE

Try to upgrade it 3.52 first and then jump to the latest 3.90. If you want to keep a CFW then check out http://www.dark-alex.org/ for more info.

Worst case you might have to 'unbrick' it with a Pandora's battery. See http://forums.qj.net/f-psp-pandora-discussion-207/t-guide-make-the-perfect-pandoras-battery-124530.html for a really good guide on how to make your own safely and the steps needed to 'unbrick' a corrupt PSP.

Your psp probably was hacked before and the idstorage was messed up. If you are luckly running on 1.5 firmware, you can run homebrew programs such as idstorage change and idstorage manager to fix the problem, then proceed to firmware update.
