Disclaimer: This can potentially make your PSP into a dead paperweight if you try it. This has not been verified or tested by any of the psphacker staff, nor by anyone of notable reputation that we know of. This is reported as news that could be potentially very interesting, but if it follows the trend of previous articles of this type, it is just another fake.

1.You need a wifi card example D-LINK DWL122.

2. Set your dwl122's IP, then you must set psp's NETWORK SETTINGS as INFRASTRUCTURE MODE and SSID is your dwl's IP. Then go to psp's GAME SHARING to connect your PSP and PC, or you can use kai to try.

3. Then you must use software such as superscan to scan the ports which PSP has. Usually it's in 31XXX~62XXX

4. If you succeed in scanning the port, you can login to your PSP in Internet Explorer. For example: http://192.168.1.1:31413.

Then you can replace the folder, but you can't replace "data" files.I think it possible in using.
