In a nutshell I'd like to know what the big deal is about owning a PSP with a TA-082 mother board. That's what I have & I want to downgrade it, yet still enjoy the benefits available through the most current firmware. I don't know if this is possible, but that's why I'm posting this thread ^.^ I've spent 3 days going from store to store & opened 12 PSP systems to only find that every single gosh darned one of 'em appear to have the TA-082 mother board. When I open their UMD doors I can read "IC1003" on the green pcb board. I thought I lucked into a different mobo since the box code had the letter "K" instead of "P,Q, or R", but no such luck. It was just another IC1003 motherboard. I've never owned a PSP before & am bound to ask questions that have been dragged through the dirt by millions before me. I apologize in advance to testing your patience. Here is where I'm at: > I'm brand spanking new to the PSP system > Own a TA-082 mobo PSP with 2.71 firmware (out of the box) Also own TA-082 w/ 3.11 firmware (out of the box) > Have 2 copies of Lumines (one normal, the other is Greatest Hits) > I want to downgrade to whatever firmware that offers me the best I can get from my new toy. So, since I'm the (proud?) owner of a TA-082 mobo PSP...what is it that I can't do that every other PSP mobo is capable of doing? How do I get the most out of my apparently limited console? Any & all help is so very, very much appreciated. Thank you in advance for your time & patience EDIT: OK, so I've been busy reading up on these forums & came accross a thread talking about downgrading by using Lumines. This quote has me concerned, "VERY IMPORTANT: If you have a TA082+ motherboard and you downgrade to 1.50, currently you will be unable to upgrade to 3.30+ Sony firmware. This is due to Sony blocking updates when the PSP has been modified to run 1.50. There will be an application released later which will allow users to revert the changes. If you are using a TA082 motherboard then I would suggest just using 1.50 or OE until an application is released." What is the highest level or most up to date "OE" I could use?
