Recently released PSP unbricking method

[CFZero.Exe]

Now Im skeptical about posting here, but I figured this is important gaming news (For at least the sony community), so it belongs here. Its not breaking any rules as I can see, its just news and instructions.

Dark_Alex and his team have discovered a way to unbrick PSP's. It involves using a battery and an official memory stick duo pro. The instructions are listed below (Id post a link but my luck it will be said to be advertisement. I want it known that these instructions are not my own work, but those of Scotty1982 of the maxconsole community, all credit goes to him for these instructions.

First, i'll list what you need:

1. a PSP with firmware 1.50 or custom firmware.

2. a battery for your psp, a spare one if you plan on leaving it a pandora's battery, otherwise you can do it if you only have one battery (but you'll need to predict when your psp might brick and make it a pandora's battery before that happens, however if you're only using it for downgrading other peoples or your other psp's, one battery will be fine):
(can be generic or the original)

3. A Memory Card that you can use with your PSP that has more than 32MB.
(can be a micro-sd in a adapter or a sd with a adapter) but less than 4GB.

4. The Pandora's Battery files:

5. The Official PSP Firmware version 1.50

6. either psychic intuition to understand the readme included with the pandora's barrety files or this simple guide.

OK, now that we have that covered, let's go through the steps:

1. Turn on the PSP with the battery inside it (not just plugged in).

2. insert mem card you'll be using into the PSP (you will lose the files on the card, so back them up if you want to keep them)

3. Connect the USB cable.

4. on the PSP, go to USB connection.

5. go to 'My computer' on your PC.

6. right click on the drive that is your mem card, we'll call that drive letter X later in the guide, so every X in the guide, replace with your mem card's drive letter.

7. Click 'Format'

8. when the format options window comes up, leave the 'filesystem' as "FAT32" and make sure "Quick Format" is NOT selected (don't worry, flash cards format quickly)

9. Click 'Start' to begin the formatting process.

10. Once that's finished, click 'OK' and close the memory card folder.

25-D. If you are using the new 'Leaked Edition' firmware, Create a folder called GAME inside the PSP folder.

26. Copy the folders inside the installers 'battery' and 'installer' folders (you should be copying 4 folders) to the GAME or GAME150 folders you just created.

27. Rename your PSP Firmware 1.50 Update file to UPDATE.PBP

b. remove memory card from PSP.
c. Plug in PSP Power Cord (wall charger)
d. Turn on PSP.
e. Insert Memory card and battery.
f. go to games and run the pandora's battery creator program.
