Unflash

[Distortional]

You can just use the program you flashed it with but be sure to have custom firmware installed as if you get a brick you can recover it

Hey, i'm new to this forum by the way. It's helped me out a real lot so I thought i'd start contributing ...

I installed the custom firmware just cause I wanted the WLAN switch to work in that way. How does it recover a bricked PSP? Tell me more please

X-flash can be used to return your psp to factory, uninstalling custom firmware and all, and all in one simple action!

Is that if you've bricked it too?

If you have bricked you psp with no custom firmware installed that is it there is nothing you can do

I have the custom firmware installed, I haven't bricked it. I'm just curious of how the custom firmware works and why sony didn't include a piece of software to fix bricked psp's.

You can restore a modded 1.5 firmware to origional flash settings by obtaining a clean firmware dump and flashing it to the psp using a program called "themepsp"

This will remove any custom fonts/gameboots/bootsounds/ etc. But you will still have harleygs custom firmware.

Then you can enter recovery mode of harleygs custom firmware (hold switch) and remove it.

Now you will be left with a 100% clean firmware 1.5

You can obtain the clean 1.5 dump from psp-hacks.com I believe.

Or you can dump it yourself

Ohhh ok. Sounds cool. So is this custom firmware tied to anything? Like I have 1.5 with a devhooked 2.71. If I say, went to 2.71 SE revision B ... and got rid of devhook and stuff ... what would happen?

Well if you modify your firmware and then dump it from your own psp, you will be getting a modified firmware dump.
But if you want to flash a clean unchanged firmware to your psp you will have to obtain a clean untouched dump. You therefore cant do this on your own psp if you have already modified it. It will just mean that you will be reflashing your psp with your own FLASH0/FLASH1 files, and therefore nothing will change.

Hence you need a clean 1.5 dump from an unmodified firmware.
