Things about PSP Custom Firmwares

As we knew,at present,there are really only 6 custom firmwares for PSP, included : the famous 5.00 M33-6, 5.03 GEN-C, 5.50 GEN D-3 Final, 6.20 TN, 6.20/6.35 PRO and 6.39 ME. and in fact,this six custom firmwares we classify two types :
1. Full Custom firmware
Features :
It relies on the use of the pre-ipl exploit and flashes a custom ipl onto your PSP. This makes the CFW firmware permanent on your PSP, where it will always be on CFW even after a shut down. These types of custom firmwares are only available for PSP 1000s and certain PSP 2000 models (Non Ta-088v3). These PSPs are termed fully hackable and allows the use of a PSP1000 Pandora Battery (just for PSP1000) and Magic Memory Stick to recovery from a brick.

5.00 M33-6, 5.50 GEN-D3 and 6.39 ME.
2). Light/Partial Custom Firmware
It relies the use of a kernel exploit and rebooting the PSP into a Homebrew Enabled (HEN) Environment. This method is really only used on PSP 2000 with newer motherboards (Ta-088v3), PSP 3000s and the PSP GO. This is used because these new PSP models, patched the pre-ipl exploit, rendering the old method of full custom firmware not possible. These new PSPs cannot recover from a brick with a Pandora battery and Magic Memory Stick also
What's more,Light custom firmwares usually involves flashing new modules to flash0 on the PSP, without replacing any existing ones, offering most features, if not all features of a full custom firmware.
The striking Features lies in they only flash additional modules, the chance of bricking is minimal.
