Up until now, all of the 2000 (with TA-88 V2 or V3 Motherboards), 3000, and Go PSP models have been lacking Homebrew if they had any Firmware past 5.03. But now, a new Homebrew Enabler titled "6.20 TN" will make it possible to... well, run Homebrew on ANY PSP model. Firmware 6.20 has been an obstacle for the PSP scene for a while now. This is a breakthrough -- the last Homebrew Enabler, ChickHEN, working alongside CFWEnabler and later 5.03 GEN-C, allowed a Custom Firmware to grace the previously unhackable PSP Models. In otherwords, PSP 3000 and PSP Go + Custom Firmware = WIN. Coming soon. Source.
