Copy the version.txt file to your computer
Start your PSP and hold R to open the recovery menu.
Connect a USB cable then under the advanced option select toggle Flash0.
Doubleposted Message Below:
Once it opens the flash0 on your computer use the version.txt from the dump to overwrite the one on flash0.
Disconnect from the computer, make sure the use version.txt option is enabled in the recovery menu under configuration and that should do it.

Sorry for the double post. The site was being stubborn and giving me the page not found error when I went to post my response
