PSP WITH IDXFFFFFFFF ERROR

[rafamartgm]

Hello everybody!

I have a PSP model 3000, a while ago I installed a chronosswitch to downgrade 6.20, I don't remember if it was one of you, after that I can't install any current original CFW from Sony, I saw in a post that some change the device from 09 to 04g and so it doesn't get updates.

Well, they told me to update versions 6.3x and still nothing, I tried running your Chronoswitc 5 and 7.1 and again it gave me an error. I don't know what to do anymore, help me, please!
