// PS: THIS ALSO WORKS ON ANY PSP-1000/2000 too.
Coldbird has announced his brand-new PSP CFW 6.20 PRO-B4, which has been released and is flashable to all previouse un-hackable motherboards up 5G.
For anybody on the PSP scene this is a Massive breakthrough that was first discovered when coder 'Virtuouse Flame' released a patch for PSP-1000 models that could permanently flash the HEN '6.20 TN-D' into the flash0/1. After a while users became curious as to the possibility of this working on a PSP-3000 & Go, and tested it, risking there models for the scene. After a day reports flew in to PSPGEN and pspslimhacks.com of successful attempts on PSP-3k & Go.
below you will find the downloads and the links to his blog.
