Ever since I upgraded my PSP to firmware 3.02OE-B, and now 3.03OE-A, I’ve had a problem with the background disappearing each time I reset my PSP. It turns out that this is to do with a couple of folders not being created on the Flash1 bios of the PSP.

There have been several suggestions as to how to remedy this, including doing a ‘reset to default’ on the PSP, which didn’t make any difference on my PSP.

In the end I decided to add the missing folders to my PSP’s flash 1 by hand, but this then raised another issue, how? Everyone I spoke to recommended using File Assistant, but the version I had would only display the flash 0 and flash 1 contents, but not actually create a new folder (both the flash 0 and flash 1 came up with read only next to them).

After much hunting around, I found an old version of File Assistant (0.04) that will allow you to write to flash1. You can download this version of File Assistant here.

Extract the rar file and copy the 1.5 firmware version of File Assistant onto your Memory Stick Pro Duo, in the GAME150 directory. Run the File Assistant program on your PSP and use the left shoulder button to select the disc option at the bottom of the screen (highlighted in red). Press the right shoulder button to execute the command. You should then see a dialog box where you can select the PSP Bios 1 (or Flash1) folder. Press O and you should see a single folder called registry and a file called config.se. It is here that you need to create the first new folder, called vsh. You then need to create a sub folder under vsh called theme. You can create folders by using the relevant comands at the bottom of the screen in File Assistant.

Once you have created the new vsh/theme folder, reboot your PSP and select a new image as your background. You should now find that the PSP does not lose the background information once you have completed the above.
