As some 2.71 PSP’s say hello to the world, others will be saying goodbye at the same time as a downgrader has been released just a few moments ago!!
For this one occasion, I grant you permission to jump on your computer’s desk; jumping up and down until you have broken your desk. The reason for such a command is that after you have done it you probably won’t care about the desk, as you have just read that a 2.71 downdater (downgrader) has now been made available! Yes, that’s right – all you 2.71 owners (who do not have a TA-082 motherboard) will be able to downgrade your PSP to firmware 1.50.
Now GO DOWNGRADE Your 2.71 PSP Now and start playing that SNES Emu you love so much on your PSP
