Does the 2.6-1.5 dwngrade have to use a GTA UMD? Can it simply be executed without the GTA? Also, when I read the guide it said something in the requirements for the dwngrade that had me worried. Can a PSP that was purchased with version 2.5/6 on it be downgraded?

The 2.5/2.6 downgrader does indeed require GTA(the unpatched, older version).

The downgrader requirement that you were worried about was the need for a non-TA-082 motherboard. You can see if you have one by looking in the UMD slot at the top right corner of the motherboard, as shown here (http://www.modchipstore.com/support/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=164)

0okm has been working on a downgrader for TA-082 motherboards with Firmware version 2.5, but I am unsure as to the safety or the progress of the program.

If your 2.5/2.6 psp does not have a TA-082 motherboard, you can safely downgrade using GTA or upgrade to 2.71 and downgrade without GTA.

How do you know if it has a TA-082 motherboard?

Open the UMD drive and look in the top right corner, where you see a little green. If there is any writing there, than it is a TA-082 motherboard.

Ok I opened it up and I see no green in the top right corner. Can someone provide a pic of where I should be looking/what I should be seeing? ^^

EDIT:Ok so if it has no text in the upper right corner, does that mean that I CAN'T do the downgrade without GTA? I see text in the upper left but not the right...

Yay! XD So if I don't have text in the upper right (with the back of the PSP facing me; the upper right), but I have text in the upper left that says IC6001, I can downgrade without using the GTA?

I have the blue, but not the red. Can I downgrade without GTA? I just want to be really careful; I just bought a brand new screen for my PSP after I broke it, and I don't want to put my PSP out of business for months again/forever. >.<
