3.71 in general, doesn't matter, ofw or cfw, can have official themes. alot of themes have been converted for 3.71, but are all loaded from the ms, not flash, reason for this is sony secured the flash, so anything overwritten to flash bricks the psp. cxmb is a program that lets you have coldboots and cintros. im sticking to 3.52 M33-4 until i need 3.71 for a game or if i suddenly get slim
