Yes, launch a program that loads itself fully into into memory, then unassigns the flashes, formats them, and writes new contents. Hellcat's recovery flasher is generally the tool used, you can get "packs" for it to install various CFWs, but it comes with the ability to flash M33 by default. This can also be used to downgrade.MrCooper said:Is there such a way to "flash" a PSP 2001 w/o a pandora
Of course it requires that your PSP is hacked in the first place to run, and will only flash fully-hackable PSPs.
