This program may bricker your console. In addition, it is a beta version, which is more likely to contain bugs or even bricker your console, the final versions.
Or psp or the developer of this program will be responsible for any brick.

The PRO Team never stops. Since January, the team now consists of Coldbird, Virtuous Flame, NPT and Neur0n continue to update their custom firmware . Progress in these few months is impressive: three different versions have been posted (6.20, 6.35 and 6.39), a patch will install the permanent 6.20 PRO final on a PSP , etc..

Today, it is not a stable release which is online, but rather a Nightly Build , that is a version beta . This means that the bugs are more common, and that the risk of brick may be higher than usual.

If wee offer this version is simply because it is the only one, until the line of Custom Firmware 6.xx PRO-B8 (or 6.xx PRO-C ), allows the use the popsloader .

Aside from that, wee do not yet know what brings the Nightly Build , no README was available

USE AT YOUR OWN RISK! Nightly Build ARE SUPPORTED IN NO WAY!
