I have a TA-082 PSP which was downgraded to firmware 1.50. I am selling the PSP and would like to install the official PSP firmware on it, but when trying to upgrade I get DRNFFFFFFD7.
I'm pretty lost at what I need to do exactly to be able to put the offical firmware on my PSP.
I think I need to use Chilly Willy's IdStorage Manager, but I'm afraid I don't know exactly how to use it. And there was a disclaimer in the readme which states I need to have a firmware installed that will work with stock keys, which I don't think the 1.50 version I have will.
Thanks for you help.
