The PSP-3000 series is a updated version of the PlayStation Portable Slim and Lite (PSP-2000), released in 2008. In comparison to the Slim and Lite, the PSP-3000 has an improved LCD screen with an increased color range, five times the contrast ratio, half the pixel response time to reduce ghosting and blurring effects, a new sub-pixel structure, a microphone, a new disc tray design, new button designs and logos, and anti-reflective technology to improve outdoor playability. The homebrew community were initially unable to hack the PSP-3000 because it had a new CPU (motherboard revealed to be TA-90v2) which does not support the PRE IPL Exploit used in hacking the previous versions. This is due to the Motherboard having its own PRE IPL where it checks the firmware thoroughly, if passed the PRE IPL is cut off entirely to prevent unwanted modifications to the system. In November 2008, Datel announced a "Lite Blue Tool" battery which allows the PSP-3000 to boot into service mode. This battery is not able to start homebrew as the new PRE-IPL has yet to be cracked.  The Lite Blue Tool was deterred from distribution due to legal action by Sony.  Some time later, Datel changed the name from Lite Blue Tool to Max Power Digital and changed the description.
