I can’t find a firmware downloader. I’m running an official sony firmware 3.95. I’m a noob and need help.

I actually don’t think this guide is perfectly clear. I don’t know what directory to extract the files to because the zip file has multiple directories within it. Do I extract every file from every folder within the zip file to /psp/game150? Wouldn’t some of the files be overwritten? I want to try this, but I’m still not sure…

thanks for the guide works absolutely perfectly - some advice - be PATIENT while waiting for the creator to run, took about an hour on my psp for some reason.
thanks again

While waiting for the actual upgrade, i impatiently pressed up, left, down, right on the d-pad out of fear of the lack of response my psp gave me… Did this mess up my psp or should i keep waiting and hope?

While I was attempting to copy the files, I get the error: The device is not ready.

Any suggestions?

Just backup the contents of your memory stick to your computer before you attempt the upgrade.

Hi, does it format your memory stick in any way?

‘Cse I want to use the memory stick that I use for playing games and I am afraid that my Saved Data may be lost during the upgrade.
