    you can do it without pandora's battery or game exploit. go HERE and look at the 2.71 section

    If you have TA-082

    then ur keys might mess up..or maybe not but

    the keys in the flash are not the originals

    so u have to use that cleaner so u can avoid possible bricks

    thats only if u have TA-082

    I used this video thing downgrader2.71full. It tells you how to downgrade your psp step by step. realy easy, cant get any easyer.I ran the program again and I realized that it tells you if you have a TA-082 and I dont. so now that I have a 1.50. how would I get the 3.71m33-3? do you know?
