I have a new PSP 2.71 TA-082 I know there are downgraders to 1.5 available I know there are custom firmwares available ie 3.40OE I know you can emulate via devhook newer firmwares I know the 1st option you take the risk of bricking your PSP, if your a moron and don't follow the instructions. My questions are as follows. Based on your answers I will choose what method to apply to my PSP I have searched but can not find the answers to these in a clear way. If I were to load 3.40OE from Dark_Alex can I downgrade back to 2.71 at a later time? or do you actually load 3.4OE thru devhook? Just what are the TRUE advantages to going to 1.5 vs saying loading 3.40OE? There are so many hacks and so many nubie guides, but they are mostly out of date. Does anyone have a compairson of the methods available and what they can do can not do? I will continue reading and searching on this. I also will be making a FAQ for these issues since I can't find one! Thanks ALL!!
