Install PSP Custom Firmware without a Pandora Battery

The usual way of installing custom firmware is to do it via Pandora Battery and that’s where the problem begins. You have to HAVE a Pandora Battery in order to make one (which means you need 2 batteries. One that’s already a pandora battery and one that you want to convert to pandora). The easy way out of this is simply buy a Pandora battery online. If however, you have a hackable PSP (one that can install custom firmware natively), you can install custom firmware without a Pandora Battery.

Important: If you have a PSP-3000 or a PSP-2000s with TA-088v3 (and versions above it) DO NOT TRY THIS ON YOUR PSP. If you do, congratulations, you now have a PSP paperweight. This method WILL BRICK your PSP.

Also, if you’re already on 5.50 ofw, then this guide won’t work. You really need Pandora to flash your PSP.
