I have 3.51 OFW right now and all the downgraders I can find are for 3.50 OFW and below. I went and bought Lumines for no apparent reason; i hate that game. Anyone who knows how to downgrade 3.51 OFW, please email me or post. Thanx

Asn there is no downgrader

Asn there is no downgrader for 3.51 yet, you have two options. Either create a "Pandora's Battery" or wait until a higher downgrader is developed. If you are unfamiliar with "Pandora's Battery" then google it. I suggest reading into it thoroughly before trying anything, and its best to use a seperate battery and memory stick. Hope that helps Deedkid

Thanks for your response, but everything I have read seems to have conflicting information. Some say once you have Pandora's battery you all ready have to have a non OFW to use it. Others are saying you have to take a battery apart and cut a wire while other instructions mention nothing about this. I did find someone selling pre-made Pandora's Batteries on ebay, any thoughts on that? Also I bought an addon battery pack for the PSP from best buy that lets you place 3 AAA batteries in the case, would that work for a Pandora's Battery?

no worries, yeah there is a lot of mixed information that goes around about pandoras batteries. But having made one myself i can tell you it doesnt involve any actual modification of the battery like cutting wires etc. Currently i believe you do need to make one using a psp that already has custom firmware, but i remember googling something and seeing a title on how to make one without, however i didnt read it so it may be the false information you are referring to. If you know anyone else who has a psp running CFW you could ask to use theirs. Regarding buying them off ebay, i think alot of people will agree with me that this is kind of risky, they usually charge high prices and without being offensive if you have limited knowledge on them they can be a waste of money,as you dont know if they have functioned properly. Finally the battery that you bought that uses AAA, i am pretty sure would not be able to be used to make a pandoras battery. The only thing i can suggest is keeping an eye on this site, there is always new downgraders and such coming out so soon enough there will be one that you can use. Best of luck Deedkid
